How to Make a Soothing Calendula Poultice

-

Herbal poultices are simple, traditional remedies used topically on the skin to relieve pain, infection, and swelling. They are water-based, which makes them especially choice when oil-based remedies (that hold in moisture and heat) are contraindicated. Herbal oils and salves shouldn’t be applied to weepy skin conditions or bacterial and fungal skin infections because they can hold in moisture and reduce airflow. Additionally, I find that herbal poultices are often more effective topical remedies than oil-based herbal preparations, simply because poultices are more concentrated, as they contain plenty of fresh herbal material.

In general, herbal poultices are beneficial for poison ivy rashes, weepy eczema, hives, insect bites, psoriasis, pimples, boils, fresh sunburns, and fungal and bacterial skin infections. The specific herbs used affect the exact medicinal properties of each poultice.

Poultices are prepared by blending therapeutic plants (fresh or dried) into a green slurry or paste, after which they are applied directly to an afflicted area. The slurry is then covered with a clean, dry cloth or bandaging material, depending on the size of the area being treated. Adding a binder such as clay makes the poultice easier to apply and helps it stay put. Clay has its own skin-healing benefits as well and is especially helpful for drying weepy skin conditions such as poison ivy.

As you might surmise, poultices can be a messy business. A tamer version involves wrapping the moistened herbal material into a loose-weave, permeable cloth and placing it on the area to be treated. The most primitive version of a poultice is the aptly named chew and spit poultice, which is applied, as you might imagine, solely on one’s own body.

Below, you’ll find one of my favorite poultice recipes. Take note that this recipe uses fresh herbs. If you’re working with dried herbs, bring a small amount of water to a boil, turn off the heat, and add a sufficient amount of the dried herbs until the herbs rehydrate and forms into a thick paste. Stir and let cool for comfort of application.

Soothing Herbal Poultice Recipe

This cooling and moistening poultice is helpful for dry, irritated skin conditions such as psoriasis, rashes, chicken pox, and chafed skin. It can also be used to soothe insect bites, mild abrasions, cuts, and scrapes. The combination of herbs provides a soothing blend of healing properties that are demulcent, anti-inflammatory, and vulnerary (wound-healing).

  • 1 handful fresh calendula flowers (Calendula officinalis)
  • 1 heaping handful fresh violet leaves (Viola sororia and V. odorata)
  • 1 heaping handful fresh plantain leaves (Plantago spp.)
  • 4 to 6 ounces very hot water (not boiling hot)
  • 2 Tablespoons powdered clay
  • 10 drops lavender essential oil (Lavandula angustifolia), optional

Yield: About 2 cups

Using a food processor or a blender, combine four ounces of hot water with all other ingredients until the poultice is smooth, with the consistency of pesto. You may need to add more herbs, clay, or water to achieve the desired consistency. Refrigerate for up to three days, and apply as needed. If using dried herbs, substitute ¼ cup (60 ml) of the dried herb for one handful of fresh herb.

If you’re looking for an herb to soothe and repair digestive issues, the cheery flowers of calendula (Calendula officinalis) will be one of your primary allies. Calendula tea is commonly used to help remedy peptic ulcers, gastroesophageal reflux disease (GERD), and inflammatory bowel disease (IBD). It supports the healing of gastric and intestinal inflammation from infection or irritation through its vulnerary (wound healing), anti-inflammatory, and antimicrobial actions.

Calendula can be combined with licorice (Glycyrrhiza glabra), slippery elm (Ulmus rubra), marshmallow root (Althaea officinalis), and meadowsweet (Filipendula ulmaria) as a natural remedy for GERD, which commonly affects people with the symptoms of heartburn. In the case of peptic ulcers, calendula can be taken concurrently with antibiotic therapy (to address the presence of the bacterial infection of H. pylori or Helicobacter pylori), and then continued for two weeks after finishing treatment. See the notes below for important contraindications.

For a more detailed guide to calendula’s expansive medicinal benefits, visit my article on Growing and Using Calendula.

Safety and Contraindications: Do not use calendula internally during pregnancy since it has traditionally been used to bring on menses. As calendula is in the aster family, it may cause a reaction for people who are highly sensitive to plants like ragweed (Ambrosia spp.) and chamomile (Matricaria recutita); this possibility is rare, but sensitive individuals should proceed with caution when using calendula for the first time. Rare incidences of allergic contact dermatitis have occurred with the topical use of calendula.

Digestive Calendula Tea

This tasty tea blend is helpful for acid reflux and helps to reduce heartburn through the anti-inflammatory, astringent, and demulcent actions of the herbs. This tea is also helpful for soothing sore throats, peptic ulcers, and inflammatory bowel disease (IBD). It can be sipped on as needed or taken daily to help reduce the symptoms of gastroesophageal reflux disease (GERD). See below for contraindications for the herbs in this formula.

  • 2 parts meadowsweet leaves and flowers (Filipendula ulmaria)
  • 1 part marshmallow root (Althaea officinalis)
  • 1 part calendula flowers (Calendula officinalis)
  • 2 parts licorice root (Glycyrrhiza glabra or G. uralensis)

For every 8 ounces (240 ml) of water, use 2 teaspoons (10 ml) of the herb blend. Place the desired amount of herbal blend and water in a pot and bring to a boil. Simmer for twenty minutes and take off the heat.

Strain and sweeten with honey or maple syrup if desired. Drink one to three cups a day.

Because this tea is best taken tonically (daily), I find it’s helpful to pre-mix a jarful of the dried herbs (in the proportions given above) to store in your cabinet and dip into whenever you’re brewing a batch. Along these lines, I prefer to infuse one to two days’ worth of tea at a time (stored in the fridge). Dosage is up to three cups per day.

Safety and Contraindications: This formula should not be taken internally during pregnancy because of the calendula and licorice (instead use slippery elm alone). The use of meadowsweet is cautioned in people who have aspirin sensitivity (or sensitivity to other salicylate-containing drugs). Meadowsweet may thin the blood; therefore, monitor coagulation values with people who are taking pharmaceutical blood thinners (the evidence for meadowsweet’s effect on coagulation is inconclusive). Marshmallow has no known adverse effects.

Licorice is contraindicated in pregnancy, water retention (edema), heart conditions, and high blood pressure. If licorice is not advisable, omit the licorice from the tea blend, and use a DGL licorice (deglycyrrhizinated licorice) preparation instead. Use the same proportions for the remaining herbs in the formula if you’re omitting the licorice.

See the notes above for contraindications pertaining to calendula.

Calendula’s sunny blooms are an external remedy for practically every manner of skin complaint. The flowers are used topically as a wound healing, antimicrobial, and anti-inflammatory herb. For optimal strength, be sure you’re using the whole flower—including the green flower base—instead of the “petals” only (the herb is sometimes sold this way). Calendula-infused oils and salves are some of my favorite topical applications for soothing and repairing the skin—see my recipes below.

Calendula is also an edible flower, a cheerful garden medicinal, and an internal remedy for the digestive and lymphatic systems. Take a peek at our article on Growing and Using Calendula for more on this plant’s floral intrigue. It’s incredibly easy to grow your own calendula, and it’s one of the most beautiful medicinals for the garden.

How to Make Herbal-Infused Oils

Herbal oils are made by infusing plants into high-quality oils that have a long shelf life and readily dissolve into the skin. I typically use extra-virgin olive oil. If your oil is for massage or broad application, consider using sesame, sunflower, coconut, jojoba, or sweet almond oil. Look for oils that are unrefined and cold-pressed or expeller-pressed. Preparing herbal oils is quite easy, especially if you follow a few basic guidelines (see our recipe below).

After preparing an herbal-infused oil, you may then use it as a stand-alone oil or transform it into an herbal salve by adding beeswax or carnauba wax (a vegan alternative), and other optional amendments like essential oils and vitamin E.

In general, herbal salves are beneficial for soothing skin irritations, dryness, and inflammation. We share our recipe for Calendula Salve below.

As mentioned previously, take care that you use the whole dried flowers when making oils and salves, as calendula’s medicinal resinous oils are found mostly in the involucres (green bases of the flower heads). Sometimes calendula is sold as “petals” only; this is a weaker medicine for topical use.

When to Use Water-Based Applications Versus Infused Oils and Salves:

In certain situations, the application of herbal oils and salves is not recommended. Oils and salves hold in moisture and heat and are thus contraindicated in weepy skin conditions, infections, and fresh burns.

Avoid the use of oils and salves on poison ivy rashes, weepy eczema, pimples, boils, fresh sunburn, and fungal and bacterial skin infections. Another contraindication includes deep wounds and cuts. Instead of oil-based preparations, use water-based applications such as herbal compresses, soaks, baths, and poultices. Also note that if oils are used as a sexual lubricant, they can degrade and break most condoms.

-

Infused Calendula Oil

This is a wonderful all-purpose herbal oil. It can be used as a base for salves or prepared into a cream or lotion. Combine it with other skin-healing herbs for a soothing anti-inflammatory and wound-healing remedy. I keep calendula oil stocked in my refrigerator, as it’s a handy stand-alone remedy. I like to combine the flowers with plantain (Plantago spp.), chickweed (Stellaria media), Saint John’s wort (Hypericum perforatum), and violet (Viola sororia and others), but calendula oil can just as easily stand on its own as a versatile skin-healing preparation.

  • 1 cup whole dried calendula flowers (Calendula officinalis), or combination of herbs mentioned above (equaling to 1 cup)
  • 1 cup extra-virgin olive oil (or substitute jojoba or almond oil)

Yield: ¾ cup (360 ml)

Note: You can double or triple this recipe by following the same proportions outlined above: 1 part herb (or combination of herbs) by volume to 1 part oil by volume.

Preparation:

Step 1: Dry your herbs. If you're using homegrown or gathered herbs, gather your plant material and dry thoroughly. If purchasing dried herbs, make sure they are fresh and high quality. It’s important to remember that oil can ferment or mold in the presence of water. If you are new to preparing medicinal oils, I recommend using dried herbs rather than fresh herbs. You’ll also want to make sure all your tools are completely clean and dry.

Step 1: Gather and dry your herbs

-

Step 2: Combine the whole dried flowers with your oil of choice in a blender, food processor, or Vitamix and aim for a thick, pesto-like consistency (see the photo in Step 3 for an idea of the desired texture). This increases the surface area of the herb(s), leading to a stronger oil (concentrated). 

Step 2: Measure out your herb(s) and add to blender or food processor

Step 2: Add your oil to the herb(s)

Step 2: Add your oil to the herb(s)

-

Step 3: Heat the herb/oil mixture in a double boiler for four to eight hours. You can improvise a double boiler by nesting two pots together or placing mason jar bands upside down in a saucepan filled with water. The trick is to nest one pan (for your herbs and oil) inside the other (filled with water) without the bottoms touching. Heat slowly and keep on low heat for four to eight hours. Try not to let the oil get hotter than 110°F, or 43.3°C (a little warmer than bath water). Watch closely to make sure the water does not completely evaporate and the oil does not get too hot. You do not want deep-fried herbs!

Step 3: Add your herbal slurry to a double boiler

-

Step 4: Strain your oil. After your oil has infused for four to eight hours, strain it into a glass jar or measuring cup using a muslin cloth, fine-weave cloth or cheesecloth. If the oil is slightly warm, it will be easier to strain. Place the cloth in a stainless-steel or ceramic strainer and pour in the oil/herb slurry. After the oil ceases to run through the cloth, wring out the herbal material with clean, dry hands or press with a potato ricer.

Step 4: After the herbal material has infused, strain and wring with a cloth

Step 4: After the herbal material has infused, strain and wring with a cloth

-

Step 5: Label and store. Make a label and cap your oil when it cools to room temperature (this prevents condensation from developing inside the jar). Herbal-infused oils will typically last two to three years when refrigerated and one year unrefrigerated, depending on the stability of the oil used.

Notes on preparing herbal oils with the stovetop method

I’ve found that in the case of infused oils, it’s beneficial to use a little bit of heat to extract medicine from herbs. This is because oil isn’t the strongest solvent and makes for weaker medicine than other solvents like water, vinegar, or alcohol. Heat is especially helpful for melting and extracting resin into oils.

As mentioned earlier, much of calendula’s healing properties come from the resin, which is concentrated in the undersides of the flowerheads. To prepare the strongest possible oil, you’ll want to optimally extract the resin with heat. Thus, I recommend using a stovetop method for preparing your infused oil.

How to Make an Herbal Salve with Calendula

I always keep a healing salve on hand in my apothecary. Thicker than an infused oil, this remedy has extra staying power that’s amplified by the moisturizing and anti-inflammatory properties of beeswax.

  • 4 oz infused calendula oil (Calendula officinalis) by volume
  • 1 oz grated or beaded beeswax (substitute carnauba wax for a vegan salve) by volume
  • Vitamin E oil, optional (For every 5 ounces of salve, add 1 capsule of vitamin E oil, or a ¼ teaspoon of liquid vitamin E oil.)
  • Salve jars (enough for 5 ounces total)

Yield: 5 oz

Preparation: 

Step 1: Measure out your oil, and then bring it slowly up to 110°F (43.3°C) in a double boiler (see notes in the Infused Oil Recipe above on fashioning an improvised double boiler).

Step 1: Measure out the herbal infused oil and add it to a double boiler

Step 1: Measure out the herbal infused oil and add it to a double boiler

-

Step 2: For every 4 fluid ounces of oil, add 1 ounce of grated or beaded beeswax, by volume. (Beeswax beads are also sold as beeswax pellets or pastilles.) Depending on the size of your beeswax shavings or beads, these proportions will yield a salve with a soft consistency. It’s easy enough to adjust the texture by adding more beeswax or more oil. Keep in mind that harder salves will be less likely to melt in a hot car or bag but will be more difficult to apply.

Step 2: Add the grated beeswax to the warm oil

Step 2: Add the grated beeswax to the warm oil

-

Step 3: Completely dissolve the beeswax into the oil. To test the consistency of your salve, place a spoonful of the mixture in the freezer for two minutes, pull it out, let it come to room temperature, and test its hardness. If it’s too soft, add more beeswax. If it’s too hard, add a little more of the infused oil.

Step 4: Label and store. Vitamin E is often added to salve (right before it’s poured into jars) as an antioxidant to prevent rancidity as well as for its own skin-healing attributes. This is also when you would add any essential oils at the proper dilution rate. While your salve is still warm, pour it into jars, label the contents, and allow it to cool before capping. Salves typically last one to three years unrefrigerated. Refrigeration is not necessary but prolongs the shelf life.

Step 4: Pour the salve into jars

The Healing Benefits of Gotu Kola: An Edible and Medicinal Herb

Gotu kola (Centella asiatica, Apiaceae) has been a legendary herb in India and China for over two thousand years, where it’s considered to be one of the best herbs for promoting clarity, focus, and a peaceful, calm nature.

Gotu kola is both a medicinal herb and a food plant. I’m especially fond of the botanicals that are food-herbs for several reasons: one, they’re generally the safest remedies, and two, there are countless ways you can ingest them. You can take gotu kola as a tea, a tincture, or in capsules, and if you’re a culinary creative, try sneaking the herb into broths, vinegars, smoothies, and vegetable juices.

Also called brahmi, gotu kola is one of the easiest tonic herbs to grow, in the garden or in containers. Take note that there is another plant called brahmi: Bacopa monnieri is a low-growing wetland herb in the plantain family (Plantaginaceae), which also goes by the name water hyssop; it has some overlapping uses with gotu kola. This has resulted in copious confusion in the scientific and herbal literature and in commerce. Herbalists debate how their uses differ and overlap. Both are used to increase focus and mental clarity.

If you purchase gotu kola, be sure to double check the scientific name—you’re looking for Centella asiatica.

Medicinal Benefits of Gotu Kola

Parts Used:  Leaves; may include small amounts of stem, flower, and fruit

Medicinal Preparations: Tea, tincture, infused oil, garnish, infused ghee, broth, green smoothie, fresh juice, compress, poultice

Tincture ratios and dosage: Fresh leaves 1:2 95%; dried leaves 1:5 50%. Both preparations 2–5 ml (½ to 1 teaspoon) three times a day

Infusion ratios and dosage: 1-2 teaspoons (5-10 ml) of the cut and sifted dried leaves infused in 1 cup (240 ml) of boiling water three times a day

Herbal Actions:

  • Nervine
  • Antianxiety
  • Secondary adaptogen
  • Antioxidant
  • Alterative
  • Vulnerary (promotes wound healing)
  • Antibacterial
  • Anti-inflammatory
  • Diuretic

Medicinal Uses: This low-growing member of the carrot family, also known as brahmi or mandukaparni (Sanskrit), is a tonic remedy for assuaging memory loss, stress, worry, and foggy thinking.1In Ayurvedic medicine—the ancient healing system of India—gotu kola is used to increase memory, concentration, and comprehension. In the Himalayas, yogis use gotu kola as an aid for meditation.

Folklore tells us that daily ingestion of gotu kola keeps the mind fresh and promotes longevity and vitality. In Southeast Asia, gotu kola has long been credited as the source of elephants’ long life spans and exceptional memories.

In addition to its effects on the brain, contemporary herbalists use gotu kola as a wound healer, diuretic, antioxidant, nerve tonic, and antibacterial remedy.

An Herb to Promote Relaxation and Alertness

Natural healers and researchers debate whether gotu kola is a true adaptogen (a tonic herb that helps balance the body by supporting its ability to deal with physical and emotional stress). Tonic herbs are traditionally taken on a daily basis over a long period of time, as opposed to herbs that are only used on an as-needed basis. In any case, gotu kola has a long tradition of use as a tonic herb for promoting longevity, vitality, and equanimity. I find it to be one of the most useful herbs to help people feel energized, alert, and relaxed. Gotu kola is one of the safest remedies for easing stress and anxiety. See the accompanying tea recipe for inspiration on combining gotu kola with similar tonic herbs.

-

A Traditional Remedy for Wounds and Injuries

Gotu kola has long been used to heal wounds, both internally and topically. Once famous for its use in treating leprosy in India, gotu kola is used today by herbalists to treat burns, minimize scarring, heal wounds, and promote tissue repair after injury or surgery. It appears to promote wound healing through its anti-inflammatory, antioxidant, and antibacterial qualities, in addition to stimulating keratinization (an integral process of nail and hair growth) and epidermal repair (the epidermis is the outermost layer of the skin).2

One in vitro study which used an isolated constituent, asiaticoside, demonstrated the proliferation of fibroblasts, which are specialized cells responsible for producing and maintaining the structure of connective tissue. Fibroblasts are integral to wound healing.3

In my herbal practice, I use gotu kola to promote tissue repair after surgery or injury, such as sprains, bone breaks, bruising, burns, and wounds. In fact, it’s the primary herb I recommend for this purpose! Gotu kola has another benefit in this healing arena: its adaptogen-like qualities help with the emotional and physiological stress of physical trauma. Calendula (Calendula officinalis) is an herb that I frequently pair with gotu kola. Calendula flowers also promote tissue repair and support the lymphatic system in fighting infection.

In addition to its internal use in healing injuries, gotu kola is used topically, in the form of poultices, compresses, soaks, and infused oils (don’t use infused oils on fresh burns). A compress is the simplest preparation: prepare a concentrated tea, strain it, and soak a clean washcloth in the tea when it’s still warm. Apply the cloth to the affected area several times per day. The proportions of tea to water aren’t essential for this herb—simply make the tea about three times as strong as you would make a tea to drink.

Along with gotu kola’s wound-healing properties, it’s also applied topically to mollify a variety of skin conditions, including insect bites, seborrheic dermatitis, cold sores, eczema, psoriasis, and dry, irritated skin. I like to infuse the dry herb into sesame or coconut oil, which can be rubbed into the scalp to calm the mind, deepen sleep, and promote hair growth.4

Safety and Contraindications: Avoid gotu kola in pregnancy or when trying to conceive.5 A small number of people react to the topical use of the herb with dermatitis.6 Be sure to check with your health care provider before ingesting any new herb, paying special attention to any possible contraindications with medications.

Eating and Preparing Gotu Kola

Gotu kola is grown in southern Asia as a medicinal potherb and salad green. The fresh leaves are added to green drinks, which are sold as a health and energy tonic on the streets in many tropical Asian countries. The parsley-like flavor of juiced gotu kola pairs nicely with vegetable juices containing apples, ginger, lemon, and kale. Substitute concentrated gotu kola tea for the juice if you don’t have it growing fresh. An innovative way to incorporate gotu kola into the diet is to infuse the dried herb into herbal broths (see the accompanying herbal broth recipe).

Relaxation & Clarity Gotu Kola Tea Recipe

This blend is helpful for promoting relaxation throughout the day, as the herbs aren’t sedating and, instead, typically increase alertness. Tulsi, gotu kola, and milky oats are classic nerve tonics for assuaging anxiety, stress, and forgetfulness. Lemon verbena adds a splash of citrusy flavor and is a traditional remedy for imparting calm.

  •   3 Tablespoons dried milky oat tops (Avena sativa)*
  •   1½ Tablespoons tulsi, flowering herb (Ocimum tenuiflorum)
  •   1½ Tablespoons gotu kola, herb (Centella asiatica)
  •   2 teaspoons lemon verbena, herb (Aloysia citriodora)

Yield: 32 ounces (1 L)

Bring 32 ounces (1 L) of water to boil. Turn off the heat, add all the herbs, and cover for thirty minutes. Strain and enjoy warm or at room temperature. Sweeten with honey or maple syrup if desired. Drink 1 to 3 cups a day. The measurements in this blend are for dried, cut and sifted herbs (store-bought). If you’re using homegrown herbs, or fresh herbs, use larger quantities.

*If you can’t find milky oat tops, substitute oatstraw, which is simply a different part of the same plant.

Healing Herbal Broth Recipe

I help keep my family’s immune systems in tip-top shape by adding dried gotu kola to my herbal broths. This broth is high in minerals due to the seaweed and stinging nettles—fold it into chili and stews to add some of the nutritional benefits of leafy greens into the diets of picky eaters. The flavor of this broth is mild enough that you won’t notice the flavor of the herbs, especially if you add other classic stew ingredients, such as carrots, celery, or onion peels. The broth can also be used as a medicinal base for healing soups and stews when recuperating from injury, childbirth, or surgery. Since this broth is an all-day affair, start early in the morning on a day you’ll be at home, or use a slow cooker set to simmer.

  •   ½ cup gotu kola, herb (Centella asiatica)
  •   ½ cup calendula flowers (Calendula officinalis)
  •   ¼ cup astragalus root, cut and sifted (Astragalus propinquus)
  •   1 cup shiitake mushrooms, whole dried (Lentinula edodes)
  •   1 cup stinging nettles, herb (Urtica dioica)
  •   1 cup seaweed pieces, such as kombu, wakame, kelp, or alaria  

Yield: 1 gallon (4 L)

Add 1½ gallons (6 L) of water to a large stew pot. Add the astragalus, seaweed, nettles, and shiitake. If you’d like, add your classic stock ingredients at this time (see above). For those of you who prepare bone broth, go ahead and add the bones into the pot, alongside the herbs. Bring to a boil and simmer for four to six hours. Turn off the heat and add the calendula and gotu kola. Let steep for a half hour with the lid on and then strain, pressing out the plant material with a spoon and fine-meshed colander.

Use the stock as a base for soups, stews, chili, and marinades. Freeze any unused portions into large ice cubes, which are handy for adding a quick herbal boost to most any dish. The measurements in this blend are for dried, cut and sifted herbs (store-bought). If you’re using homegrown herbs, or fresh herbs, use larger quantities.

How to Grow Your Own Gotu Kola

I find that gotu kola is one of the most luscious herbal houseplants, and I enjoy its presence in my library, where it keeps me company throughout the winter as I write. When the afternoon doldrums seize my creativity, I nibble on a leaf or two for renewed inspiration.  It’s surprisingly easy to grow, both as a garden herb and as a potted plant. In zones 7b and warmer, gotu kola can be grown outdoors as a perennial ground cover, and in colder climates it can be grown as a frost-tender annual.

Gotu kola prefers moist soils with good drainage. If your soil is compacted or clayey, add finished compost, coarse sand, or pine bark fines. In milder climates, you can grow gotu kola in full sun, as long as the soil stays relatively moist, either through irrigation or by choosing a moist garden site.

In hotter climates, plant gotu kola in part shade; preferably with morning sun and afternoon shade. In my garden, I play the herbal matchmaker by pairing gotu kola with passionflower vine (Passiflora incarnata). Passionflower is trained up a tipi-type trellis, providing shade and holding in moisture for its creeping companion, who, in turn, suppresses weeds.

As a container plant, gotu kola prefers a shallow, broad pot with a saucer underneath to help keep it moist. You may need to water your plants every few days—they’ll readily wilt when they’re thirsty. In the summer, I grow potted gotu kola on my front porch, which receives full morning sun and afternoon shade. Before the first frost, I bring the plants inside, placing them in front of an east-facing window.

Whether your plants are in the garden or a container, harvest gotu kola with the “haircut method,” using kitchen scissors to trim most of its leaves. It quickly grows a new batch, offering a few cuttings per growing season.

10 healing plants for your porch or patio

Lush, aromatic plants gracing the gateways to your home—porch steps, patios, pathways, and windowsills—are the ultimate welcome mat.

In particular, potted culinary and medicinal herbs bring a little something extra. Their fragrance and beauty are a daily reminder that herbal self-care is within reach. And keeping healing herbs close at hand increases the likelihood they’ll star in your next meal or cup of tea.

Most culinary herbs double as medicinal allies, and the ones on this list are no exception. Plants that serve as both food and medicine are among my most reached-for herbs.

Here, we’re rolling out the green carpet for ten of our most essential culinary/medicinal herbs—all of which can be grown in pots and other containers with ease.

Wondering where to acquire herb starts and seedlings? Find a roll call of growers in our catalog of Herbal Seed Suppliers and Nurseries.

And for our tips on choosing containers and stirring up an all-purpose potting mix, visit our blog on Growing Medicinal Herbs in Containers.

*Please note that this article’s discussion of medicinal uses is introductory in scope. We’ve provided safety guidelines for each plant, but we recommend that you research any new herb and consult your health-care providers for possible drug/herb contraindications and precautions before ingesting.

Anise hyssop (Agastache foeniculum) is a prime nectary plant, attracting a veritable promenade of pollinators

Anise hyssop (Agastache foeniculum) is a prime nectary plant, attracting a veritable promenade of pollinators

1. Anise Hyssop (Agastache foeniculum, Lamiaceae)

Parts Used:  Flowering tops—leaves, stems, and flower spikes

Medicinal Preparations: Tea, tincture, infused honey, syrup, mead, herbal steam, infused vinegar

Herbal Actions:

  • Nervine
  • Carminative
  • Expectorant
  • Diaphoretic (stimulates perspiration)
  • Anti-emetic (anti-nausea, anti-vomiting)

Medicinal and Culinary Uses: With a spicy-sweet aroma reminiscent of licorice, anise hyssop is a gentle remedy for coughs, colds, indigestion, insomnia, mild depression, and anxiety. I like to combine it with catnip (Nepeta cataria) and lemon balm (Melissa officinalis) in teas, as their flavors meld nicely and their medicinal uses are complementary.

Children have a special affinity for anise hyssop’s sweet flavor—it can be used to mask the more unpleasant flavors of other medicinals.

In the kitchen, try adding a few finely chopped leaves to salad, herbed goat cheese, and fruit salad for an anise-like flair. Anise hyssop can be artfully woven into all manner of confections, including ice cream, sorbet, icing, cookies, cordials, and smoothies. To infuse the flavor, you can prepare a concentrated tea if the recipe calls for water, or heat milk or butter, gently infusing the herb and then straining.

I highly recommend combining anise hyssop with black birch (Betula lenta) for a delicious root beer–flavored mead or home-fermented soda. Iced tea prepared from anise hyssop, mint (Mentha spp.), and lemon balm is divinely refreshing.

Cultivation: Anise hyssop is one of the easiest herbs to grow and thrives in both hot and cool climates. In the warmer reaches of its range, it can be grown in part shade and moist soil. In more temperate regions, it will do just fine in average to dry-ish soil and full sun.

Pinch back the growing tips every week in the spring to stimulate lush new growth. The plant can grow spindly if you don’t encourage it to branch and become bushier. In addition, pinching back the growing shoots encourages more flowering stalks. Anise hyssop is a short-lived perennial, with a life span of two to three years. Divide plants after the second summer to increase their longevity.

Few plants attract as many bees, butterflies, and hummingbirds to the garden as this showy medicinal—its lavender flower spikes are abuzz with pollinators during its long flowering season.

Safety and Contraindications: No known precautions.

Three cultivars of garden sage

2. Garden Sage (Salvia officinalis, Lamiaceae)

Parts Used: Leaves

Medicinal Preparations: Tea, tincture, infused oil, compress, wash, gargle, tooth powder, infused vinegar, herbal finishing salts

Herbal Actions:

  • Antibacterial
  • Antifungal
  • Carminative
  • Antioxidant
  • Anti-inflammatory
  • Diuretic
  • Bitter
  • Cholagogue (stimulates bile)

Medicinal and Culinary Uses: Classic garden sage has a special affinity for the mouth and throat, and is treasured as a gargle or rinse for sore throat, canker sores, periodontal disease, bad breath, and cold sores. It has a rich tradition of use as a mental stimulant and is often added to formulas to aid concentration, memory, and focus.

This Mediterranean herb is unique in that it can slow breast milk production and sweating. For these purposes, it should be drunk at room temperature in small doses throughout the day. Sage is commonly employed with motherwort (Leonurus cardiaca) in reducing hot flashes during menopause.

Sage is renowned for its pungent resinous flavor, and its ability to complement fatty foods. Indeed, our taste buds may be speaking for our stomachs in this department, as sage is one of the best culinary herbs for enhancing the digestion of fats (by stimulating bile).

Many of us identify with sage as the quintessential stuffing herb; I like to combine it with generous portions of black pepper and anise seeds. Sausages are frequently spiced with sage, as is meat loaf. Sage is often thought of as the poultry seasoning, but it is equally at home with winter squash and roasted roots.

Cultivation: Sage will grow like a dream in containers, as long as the soil is well-drained. If you live in a colder, four-season climate, be sure to overwinter sage indoors in a south-facing window to avoid cold season casualties.

As with most mint family members, pinching back the growing tips during the first year will encourage bushiness. In the spring of the second year before the plants begin to regrow, cut them back by a third to discourage woodiness. Continue with this pruning regime every year to keep the plants perky and promote fresh succulent shoots. Sage is often a short-lived perennial, petering out or becoming woody after several years.

Safety and Contraindications: Sage should be avoided in medicinal doses during pregnancy. Smaller culinary doses are considered safe. Avoid during lactation, unless you are weaning, as sage will slow milk production.

Basil, nasturtium, Swiss chard, and European vervain growing with purple sorrel on the front porch

3. Basil (Ocimum basilicum, Lamiaceae)

Parts Used: Leaves

Medicinal Preparations: Tea, tincture, pesto, infused oil, infused vinegar, herbal butter, herbal finishing salts

Herbal Actions:

  • Nervine
  • Carminative
  • Antimicrobial
  • Anti-nausea
  • Diaphoretic
  • Circulatory stimulant
  • Antioxidant
  • Emmenagogue (stimulates menses)

Medicinal and Culinary Uses: Basil is best known for its culinary uses, but it is also a versatile medicinal. This spicy garden herb possesses some of the same qualities as its cousin, holy basil (Ocimum tenuiflorum). Both herbs are used to lift the spirits, impart vitality, brighten the mind, and alleviate anxiety.

Its pungent flavor and warming quality make basil an excellent aid to digestion, and it is helpful in reducing gas and nausea. Warm tea, prepared from ginger (Zingiber officinale), catnip, and basil, with a touch of added lemon juice, makes an excellent remedy for steadying queasiness due to motion sickness, illness, or the side effects of chemotherapy. The sweet taste of the tea also makes it a good remedy for children’s upset tummies.

Basil is a broad-spectrum antimicrobial for bacterial, parasitic, and fungal infections. Research indicates its efficacy against Staphylococcus aureus, Shigella flexneri, Escherichia coli, adenovirus, and herpes simplex 1 and 2.1 It can be used topically as a compress, poultice, fresh juice, or full-body bath for fungal skin infections, ringworm, and thrush.

Culinary uses are wide-ranging; my favorites include pesto, pasta sauce, and summertime salad dressings.

Cultivation: Basil is the crown jewel of the vegetable and herb garden. Equally at home in a pot as in the soil, basil does well as a container plant on patios or porches with ample sunshine.

Indigenous to the tropics, basil thrives in warm soils. Plants really take off when the days are hot and the nights are balmy (above 60°F/16°C). Soil should be fertile, but not too rich. Basil likes to be well watered, but note that watering from above when the sun is hot will result in spots and damage to the leaves.

Pinch the tips of basil every week or two to encourage bushiness and to deter flowering. Once basil flowers and sets seed, the show is all over—this is why we aim to keep basil out of reproductive mode. Pinching back the flowering tops allows the plants to live longer and remain luscious.

Potted basil can be protected from frost at the bookends of the growing season by moving the plants to shelter. An added bonus is that container-grown plants can be shielded from slugs—the nemesis of the basil gardener. The purple varieties are especially attractive in mixed herbal containers.

Safety and Contraindications: Although most women do not avoid basil as a culinary herb while pregnant, higher doses (medicinal strength) are contraindicated during pregnancy in both Asian and Western systems of traditional medicine.2

Curly and Italian (flat-leafed) parsley chumming it up in a pot

4. Parsley (Petroselinum crispum, Apiaceae)

Parts Used: Leaves

Medicinal Preparations: Tea, pesto, vinegar, infused oils, compound butters, marinades, dressings, fresh juice, bouquet garni

Herbal Actions: 

  • Carminative
  • Antioxidant
  • Diuretic
  • Emmenagogue

Medicinal and Culinary Uses: Have you ever wondered how parsley landed the starring role as garnish de rigeuer on dinner plates across the country? Perhaps it has to do with parsley’s ability to stay perky throughout a five-course meal, or it may be a nod to herbal culinary tradition: parsley has a beneficial effect on lackluster digestion; it eases gas and bloating, and freshens the breath. Parsley is also a nutritional powerhouse—it’s high in vitamins A, C, and K (which are linked to heart and bone health).

I prefer to eat parsley as a condiment or seasoning herb. I blend it into green sauces, pestos, dressings, and marinades. Throughout the summer, I also add generous handfuls to big bowls of tabbouleh.

Parsley is a folk remedy to slow breast milk production. Garden sage is likewise used for this purpose; the two are used as herbal allies in weaning. Parsley is also an emmenagogue and blood tonic; it can help to bring on delayed menses as well as encourage a healthy menstrual cycle.

Cultivation: I grow a large quantity of parsley every year so I can have it on hand throughout the warm season. Parsley is typically grown as an annual herb, as the leaves become bitter upon flowering during its second year. Harvest the outer leaves, taking only of the plant, to allow new leaves to regrow from the center crown.

In hot climates, parsley will appreciate a bit of afternoon shade, and can be planted as a fall and winter crop. Parsley flourishes in containers as long as the soil is rich and doesn’t dry out. It can be grown indoors in a sunny windowsill, and outdoors in window boxes, hanging baskets, and mixed herbal pots.

Safety and Contraindications: Do not use medicinally or consume large amounts during pregnancy or breastfeeding.

5. Mint (Mentha spp., Lamiaceae)

Parts Used: Leaves

Medicinal Preparations:Tea, tincture, garnish, potherb, powder, poultice, compress, green smoothie ingredient (for flavor), essential oil

Herbal Actions:

  • Carminative
  • Antispasmodic
  • Diaphoretic
  • Nervine
  • Anti-emetic (reduces nausea)

Medicinal and Culinary Uses: The herbs of the Mentha genus, including peppermint (Mentha × piperita) and spearmint (Mentha spicata), are some of our most essential and delicious remedies to stock in the home medicine cabinet.

The mints excel at relieving a number of common household complaints including indigestion, nausea, cramps, headaches, colds, and fevers. Peppermint, in particular, shines as a remedy for digestive issues by strengthening and soothing the stomach. It can be taken as tea for gas, hiccups, irritable bowel syndrome, dyspepsia, and for increasing appetite.

Mint is also a staple in the kitchen. During the warm months, I mince fresh leaves into salads and dressings, and churn up a batch or two of peppermint ice cream. It also makes a cooling and refreshing beverage tea (spearmint is my hands-down favorite in this case). Try our Hibiscus Mint Herbal Iced Tea with Key Lime Ice Cubes when the days dawn hot and steamy.

Cultivation: Mint is fragrant and fast-growing, which makes it a very satisfying herb to grow. There are literally hundreds of varieties to play with, including flavorful options like chocolate mint, apple mint, and orange mint.

The mints like plenty of moisture in a well-drained soil, and will thrive in both full sun and partial shade. Harvesting regularly is ideal to prevent legginess. Snip stems about down their length.

If, like me, you use a lot of mint in your kitchen, you may wish to grow it in a large container like an old whiskey barrel.

Safety and Contraindications: Mint may aggravate heartburn.3

6. Thyme (Thymus vulgaris, Lamiaceae)

Parts Used: Leaves and flowering tops

Medicinal Preparations: Culinary, tea, tincture, herbal steam, infused honey, vinegar, infused oil

Herbal Actions:

  • Antimicrobial
  • Carminative
  • Diaphoretic
  • Expectorant
  • Antispasmodic
  • Emmenagogue

Medicinal and Culinary Uses: Thyme is one of my favorite culinary herbs and is highly revered in French, Italian, and other Mediterranean cuisines. It can be added to homemade herbes de provence blends or used on its own to flavor poultry, root vegetables, stews, sauces, and marinades. Experiment with thyme varieties—lemon thyme and orange thyme both impart a savory citrus flavor to dishes.

Like many mint-family herbs, thyme is stimulating to the digestive system—easing uncomfortable symptoms like gas and bloating. Its antimicrobial activity lends it to topical wound care and for fungal and yeast infections, and internally for digestive and respiratory infections.

Thyme is one of the first herbs I add to steam pots—it helps to relieve inflammation and break up congestion. Combined with its antispasmodic and expectorant properties, thyme is a traditional remedy for painful, hacking coughs, including conditions like whooping cough and bronchitis.

Cultivation: Thyme hails from the same Mediterranean soils as rosemary (Rosmarinus officinalis) and sage, and likewise prefers similar growing conditions. Namely: full sun, warm days, and well-drained soil. Be sure to add a generous helping of sand to your potting mix and let the soil dry out completely between waterings.

Harvest thyme in a “cut-and-come-again” style; simply give the plant a haircut early in the season and it will grow back lickety-split. If you enjoy the look of mixed plantings, consider pairing thyme in a pot with rosemary and strawberries (Fragaria spp.).

Safety and Contraindications: In high doses, thyme is an emmenagogue (stimulates uterine contractions and/or menstrual flow) and should be avoided in pregnancy. Culinary doses, lower in nature, are generally considered to be safe.

7. Lemongrass (Cymbopogon citratus , Poaceae)

Parts Used: Stems and leaves

Medicinal Preparations: Tea, broth, soup

Herbal Actions:

  • Nervine
  • Carminative
  • Diaphoretic
  • Antibacterial
  • Antifungal
  • Expectorant

Medicinal and Culinary Uses: Lemongrass is one of our most delicious herbs for both beverage teas and home remedies. It’s employed around the world for a handful of common health complaints: headaches, insomnia, stress, anxiety, indigestion, coughs, colds, and flu.

I use lemongrass as a tasty medicinal tea, and add the flavorful “bulbs” at the base of the stems to Thai coconut soups, curries, and healing broths. For a refreshing herbal iced tea, I suggest pairing lemongrass with other citrusy herbs, like lemon balm and lemon verbena (Aloysia citriodora), along with hibiscus (Hibiscus sabdariffa).

Cultivation: I am a lemongrass devotee, and this aromatic herb is a mainstay on my patio. Tropical in origin, lemongrass is often grown in containers and brought indoors to be protected during the colder months. A true showpiece, lemongrass really pops when planted with other ornamental herbs, such as artichoke (Cynara scolymus) and purple sage (Salvia dorii). For a tropical aesthetic, pair with nasturtium (Tropaeolum spp.) and other cascading flowers.

To keep this warm weather native happy, situate lemongrass in full sun and provide soils that drain rapidly—consider adding extra perlite or pine bark fines to your soil mix. The stems can be harvested repeatedly throughout the growing season, with lush regrowth following close behind.

If lemongrass starts aren’t readily available in your area, you may be able to acquire pieces of lemongrass stem with attached roots from Asian grocers. These can be directly planted in pots or encouraged to root in a glass of water before planting.

Safety and Contraindications: Individuals who have reacted to lemongrass essential oil may develop an allergic contact dermatitis handling the fresh plant.

Freshly harvested turmeric

Freshly harvested turmeric

8. Turmeric (Curcuma longa, Zingiberaceae)

Parts Used: Rhizomes

Medicinal Preparations: Tea, tincture, powder, fire cider

Herbal Actions: 

  • Anti-inflammatory
  • Antioxidant
  • Circulatory stimulant
  • Cholagogue
  • Hepatic
  • Analgesic
  • Carminative
  • Astringent

Medicinal and Culinary Uses: Fiery turmeric is pleasantly warming and bitter, making it a natural ally for stoking the digestive processes. Its anti-inflammatory abilities make it a natural aid for a wide range of complaints, including irritable bowel syndrome, ulcers, leaky gut, gas, and colitis.

Turmeric also soothes pain and inflammation in the muscles and joints; it’s a classic remedy for arthritis and injuries.

To enhance your body’s ability to assimilate turmeric’s medicine, add 3% black pepper (Piper nigrum) to any preparation featuring turmeric.

Turmeric's golden-orange hue makes it a delight to use in the kitchen. During the winter months, I imbibe turmeric freely in fire cider (a spicy immune-boosting tonic) and golden milk (a warm and creamy turmeric beverage sweetened with honey or maple syrup). It’s also a traditional ingredient in curry, rice, and stir-fry dishes.

Cultivation: Growing turmeric is a sublime pleasure as its tropical greenery evokes an experience of equatorial paradise. You can grow turmeric from rhizomes you purchase at the farmers market, grocery store, or from seed companies. Try to find organic turmeric, if possible. Choose plump pieces that have well-developed nodules or growth buds.

Turmeric is a tropical plant, and prefers warmth, humidity, moist soil, and dappled sunlight to grow. Morning sun and afternoon shade is also ideal. Do not place it in direct sunlight or where it will be exposed to frost or heavy winds.

Choose a wide container and provide fertile soil that drains easily; a mixture of compost and sand works well. Fill your pot with about four inches of soil. Place pieces of rhizome horizontally on top of the soil, with the buds facing upwards. Then cover with a light layer of soil; just ½–1 inch (1.3–2.5 cm) is plenty.

Wait to take your potted turmeric outside until the days are consistently warm. If you live in a cool climate, you may want to give your turmeric a little extra love. You can place your pot on a heating pad until temperatures rise naturally, and you can create humidity by tenting an old plastic bag over your pots (alternately situate turmeric in a bathroom window or greenhouse).

You’ll want to feed potted turmeric regularly (every few weeks). You can add liquid fertilizers like seaweed extract, fish emulsion, or homemade compost tea. Once a month, you may also want to sprinkle a light layer of compost over the rhizomes.

Now, patience! It will likely take several weeks to several months (for real) for your turmeric to sprout. Then, prepare to wait 7–10 months for fully mature rhizomes. You’ll know harvest season is upon you when the leaves begin to die back. You can also harvest younger turmeric, but it may have less flavor. Dig up what you need and allow the rest of the plant to keep on growing.

Note: because turmeric requires many months of warm weather to mature, time your planting appropriately (mid- to late winter is ideal).

Safety and Contraindications: Avoid in medicinal doses while pregnant (smaller, more culinary doses are fine). Monitor use with a physician with individuals who have a blood-clotting disorder or who take blood-thinning medication. Turmeric is notorious for staining hands, clothing, and surfaces a vivid yellow. A dab of alcohol can be used to rub it off. 

Fresh ginger grown in a greenhouse in North Carolina

9. Ginger (Zingiber officinale, syn. , Zingiberaceae)

Parts Used: Rhizomes

Medicinal Preparations: Culinary, tea, tincture, powder, fire cider, vinegar, fresh-pressed juice

Herbal Actions: 

  • Anti-inflammatory
  • Circulatory stimulant
  • Expectorant
  • Carminative
  • Diaphoretic
  • Anodyne (pain-relieving)
  • Antimicrobial
  • Anti-emetic (relieves nausea)

Medicinal and Culinary Uses: This familiar warming spice is also a household medicinal. The rhizome is used in tea or tincture form to increase circulation, alleviate arthritis, and allay nausea (it’s a classic for reducing motion sickness and nausea from pregnancy or chemotherapy).

It is also a premier circulatory stimulant, making it an ally for people who run cold or have poor blood flow to their extremities. It is widely used to relieve inflammation from arthritic conditions.

Ginger is a traditional remedy for colds and flu. Taken as tea or infused in honey, it helps to disperse congestion and has an antimicrobial effect. I begin taking a gingery concoction called fire cider at the first sign of colds or flu. See our spicy-sweet Roselle Hibiscus Pomegranate Fire Cider recipe for inspiration.

Along these lines, ginger straddles the food-medicine divide with panache. It’s a traditional ingredient in tasty immune-stimulating soups and teas. I frequently add finely chopped ginger to ruby red sauerkraut recipes. Ginger takes salad dressings, marinades, lemonade, and fresh juices to the next level.

Cultivation: Ginger is closely related to turmeric, and is grown in a similar fashion. See our cultivation notes above on turmeric for all the details!

Safety and Contraindications: Ginger is heating and can aggravate heartburn. It may be too stimulating in high doses for folks who run hot.

Potted rosemary

Potted rosemary 'BBQ'

10. Rosemary (Rosmarinus officinalis, Lamiaceae)

Parts Used: Leaves

Medicinal Preparations: Culinary, tea, tincture, infused oil, vinegar, herbal steam

Herbal Actions: 

  • Aromatic
  • Antioxidant
  • Nervine
  • Antidepressant
  • Carminative
  • Circulatory stimulant
  • Antimicrobial

Medicinal and Culinary Uses: Resinous and aromatic, rosemary sprigs can be bound together with other herbal companions in fragrant smoke bundles for cleansing and purification.

Rosemary is classically known as an aid for memory and concentration in tea or tincture formulas with gotu kola (Centella asiatica) and ginkgo (Ginkgo biloba). Topically, it is astringent and makes an excellent hair wash for those with oily to medium hair.

Taken tonically, rosemary can improve circulation and quench free radicals through its antioxidant qualities. It can also calm nervous complaints, especially when digestive flair-ups are paired with tension or headache.

Rosemary is a classic kitchen herb used to spice any number of savory dishes—including poultry, fish, root vegetables, stews, and red meat. It has also become a popular ingredient in craft cocktails and mocktails.

Cultivation: Rosemary plants that attain old age are elegant and enticing beyond compare. With soft blue to purple edible blooms and a singular aroma, they are often the herbal pièce de résistance on the patio. Lucky for us, rosemary grows easily and thrives in containers.

Rosemary has a penchant for sunlight and soils that drain easily—imagine the climate and terrain of its native Mediterranean habitat. You can mimic these conditions by stirring plenty of sand into your soil mix and letting the soil dry between each watering.

If you live in zone 7 or colder, you’ll want to bring potted rosemary plants indoors over the winter and place in a south-facing window. Otherwise, you may need to provide artificial light.

Harvesting rosemary frequently will encourage plants to become lush and bushy. Using a sharp pair of kitchen scissors, snip off the top few inches of growth from each sprig.

Safety and Contraindications: Avoid using rosemary in large or medicinal doses during pregnancy and breastfeeding. Culinary doses are fine.

  • Anxiolytic (anti-anxiety)
  • Nervine
  • Antibacterial
  • Alterative
  • Secondary adaptogen*

Medicinal Uses: Gotu kola, also known as brahmi, has been used medicinally in Asia for over two millennia as a rejuvenative tonic in the treatment of memory loss, stress, worry, and foggy thinking.

It is often combined with ginkgo (Ginkgo biloba) to improve memory and concentration, while simultaneously promoting a calm nature. I add gotu kola to herbal formulas for people who have trouble concentrating or who feel scattered or indecisive, including those who experience ADHD (attention-deficit/hyperactivity disorder).

Gotu kola can be used, both internally and topically, in healing wounds. Famous for its use in treating leprosy in India, it is now used by contemporary herbalists to treat burns, minimize scarring, and promote tissue repair after injury or surgery.

Gotu kola is also used topically as an infused oil, compress, and poultice to heal a variety of skin conditions, including insect bites, rashes, seborrheic dermatitis, herpes sores, eczema, psoriasis, and dry, irritated skin.1

*Most herbalists recognize gotu kola as a secondary adaptogen, or “almost-adaptogen.” In my experience, it clearly has adaptogenic properties: it’s helpful for increasing vitality, reducing stress, balancing the immune response, and acting as a tonic for overall well-being.

Cultivation: Personally, I find that gotu kola makes one of the most luscious herbal houseplants, and I enjoy its presence in my office where it keeps me company as I write about medicinal herbs.

The key to growing this verdant herb is to provide moist soils with good drainage. Some people grow brahmi in an old whisky barrel or retired bathtub. If your space is more limited, try planting it in a shallow, broad pot with a saucer underneath to help keep it moist.

To increase the drainage of your soil mix, add coarse sand or pine bark fines. Water the plants so the soil is continuously damp but not waterlogged. You may have to water your containers every two to three days, and gotu kola will readily communicate with you through the ancient plant code of wilt.

Gotu kola can be placed in full sun if it’s well-watered or if summertime temperatures are mild. But if your summer is sweltering, gotu kola relishes some cover. In hot climates, morning sun and afternoon shade are ideal. I bring my potted gotu kola plants inside every winter to an east-facing window and then return them to the outdoors when the temperatures warm in the spring.

I harvest gotu kola with the “haircut method”: using scissors to cut off all the leaves. (See the photo above of gotu kola receiving a harvesting haircut.) It quickly grows a new batch of tender leaves, typically offering at least three cuttings per growing season.

Safety and Contraindications:  Avoid in pregnancy or if attempting to conceive.2 Although rare, some people react with dermatitis to topical use. In Ayurveda, there are precautions that high doses may lead to headaches and loss of consciousness, but it is important to remember that gotu kola is widely consumed as a food plant without incidence in much of tropical Asia.3

Spilanthes (Acmella oleracea); note the profusion of seedlings in the front—spilanthes rapidly spreads, or self-sows

2. Spilanthes (Acmella oleracea, Asteraceae)

Parts Used: Leaves, stems, and flowers

Medicinal Preparations: Tincture, tea, nibble

Herbal Actions:

  • Immunostimulant
  • Antimicrobial
  • Anti-inflammatory
  • Sialagogue (stimulates salivation)
  • Oral anodyne
  • Diuretic

Medicinal Uses: Spilanthes is a joyful herb to behold and has been one of my top ten herbal allies ever since I began growing it and using it for medicine. Its succulent leaves and gumdrop-shaped flowers are useful for a wide spectrum of infectious illnesses including colds, flu, sinus infections, and ear infections.

Clinical studies demonstrate that spilanthes is effective against pathogenic bacteria. One of the primary ways I use spilanthes is as an immune stimulant, much like echinacea species.

Spilanthes is employed as a toothache remedy in many locations, including India and Southeast Asia.4 Sometimes called “toothache plant,” it can temporarily numb the mouth during tooth infections and abscesses. (Dental infections typically require conventional dental care, with herbal care offering temporary symptomatic relief.)

Additionally, it is helpful for maintaining healthy gum tissue by increasing salivation and blood flow. The dried flowers can be added to tooth powders to address periodontal disease and prevent dental caries, or cavities.

Cultivation: Spilanthes is one of the easiest medicinal herbs to grow, and kids absolutely love its zippy-zappiness. It does well in containers and can be interplanted with other ornamental medicinals, such as lemongrass (Cymbopogon citratus) and artichoke (Cynara scolymus).

Plan to grow spilanthes as a frost-tender annual unless you live in the tropics. Transplant seedlings into outdoor pots containing average to rich soil after all danger of frost has passed.

Despite its succulent appearance, spilanthes relishes water more than most other medicinals. You may want to amend your potting soil with extra organic matter or add a bit of clay to aid with water retention. Protect the plants from slugs, as they will devour it—slug candy, indeed!

The plants are also prone to spider mites—telltale signs include mottled yellow leaves and fine cobwebs on the underside of the leaves. Also, the plants readily self-sow, so it may become a weed in your garden, although it’s typically not troublesome.

Safety and Contraindications: Immune-stimulating herbs, like spilanthes, have the potential to increase autoimmunity and have caused flare-ups in people with autoimmune conditions, although this is more the exception than the rule.

Because spilanthes is in the aster family, it may cause a reaction with people who are highly sensitive to plants like ragweed (Ambrosia spp.) and chamomile (Matricaria recutita); this possibility is rare, but sensitive individuals should proceed with caution when taking spilanthes for the first time.

Take care not to squirt the tincture on the back of your throat or chew too large a wad of spilanthes, as the throat may take offense and clamp down—not a fun exercise!

Aloe (Aloe vera)

Aloe (Aloe vera)

3. Aloe (Aloe vera; A. barbadensis, Asphodelaceae)

Parts Used: Fresh leaves and gel extracted from the fresh leaf

Medicinal Preparations: Gel, poultice, prepared juice

Herbal Actions:

  • Emollient (soothing to skin)
  • Vulnerary (wound healing)
  • Anti-inflammatory
  • Antibacterial
  • Laxative

Medicinal Uses: Every home will benefit from an aloe plant. Soothing and cooling, aloe is a useful first-aid herb for burns, abrasions, blisters, and stings.

It’s a summertime staple; helping to heal mild sunburns, after the area has been bathed in cool or tepid water. A few drops of lavender (Lavandula officinalis) essential oil can be mixed with the gel for additional anti-inflammatory action.

Aloe can also be used topically as a skin tonic for conditions like acne and rosacea, and be applied to the hair for smoothing.

Internally, aloe is a traditional cleansing herb—it is laxative in appropriate doses. It can take quite a bit of aloe to prepare the needed juice, so alternately you can use organic preserved aloe juice from your local natural foods store. Follow the dosage instructions on the bottle.

Cultivation: Aloe is truly a winsome houseplant—it’s both hardy (hard to kill) and beautiful, with its glowing succulent leaves. It is well-adapted to many climates, and can be grown nearly anywhere. I grow aloe as a potted patio plant in warm weather, and bring it inside during the colder months (aloe is frost-sensitive). Despite aloe’s succulent status, it won’t tolerate full sun; instead, give it dappled shade or morning sun. If your aloe’s leaves are turning yellow, it’s a sign that the plant is receiving too much light.

When indoors, a north- or east-facing window will keep it perky. You’ll almost certainly be blessed with aloe “babies,” which will grow from the parent plant’s roots. These can easily be separated and placed in their own pots. In this way, aloe will multiply itself for years and years.

Safety and Contraindications: Internally, aloe is a laxative and should be avoided in pregnancy and breastfeeding. For this same reason, take care and follow dosage instructions on purchased aloe juice; too much can cause painful stomach cramps.

Do not apply aloe to staph or staph-like infections; the gel creates a perfect breeding ground for staph bacteria.5

Jiaogulan (Gynostemma pentaphyllum)

Jiaogulan (Gynostemma pentaphyllum)

4. Jiaogulan (Gynostemma pentaphyllum, Cucurbitaceae)

Parts Used: Leaves and stems

Medicinal Preparations: Tea, powder, tincture, nibble

Herbal Actions: 

  • Adaptogen
  • Immune tonic
  • Antioxidant
  • Cardiotonic
  • Hypocholesterolemic (lowers cholesterol levels)
  • Hypotensive (lowers blood pressure)
  • Liver tonic

Medicinal Uses: Also called Southern ginseng, jiaogulan is a popular folk herb in Southeast Asia where it is grown as an affordable substitute for ginseng (Panax spp. Araliaceae).

It’s gaining popularity in Western herbalism, where it is used as a tonic for longevity and vitality. The leaves are brewed into a medicinal tea that can be taken for anxiety, stress, depression, high blood pressure, and high cholesterol.

Sometimes known as sweet tea vine, jiaogulan is ironically quite bitter; it has a flavor reminiscent of ginseng with mild soapy undertones. However, I enjoy the taste! If bitter tea isn’t your thing, you can combine jiaogulan with pleasant-tasting herbs like peppermint (Mentha piperita), anise hyssop (Agastache foeniculum), and tulsi (Ocimum tenuiflorum).

Cultivation: With its lush growth and star-shaped leaves, jiaogulan is easily one of my favorite herbal houseplants of all time. Given the right conditions, it becomes a rambunctious trailing vine that grows beautifully as a potted plant or in a hanging basket.

Joe Hollis of Mountain Gardens describes it as the easiest to grow of the adaptogen herbs (which are health-promoting, immune-boosting, and stress-balancing botanical tonic remedies). Joe is credited with bringing jiaogulan into popular cultivation in the West. You can hear him speak personally about growing and using jiaogulan here.

In the ground, jiaogulan can spread assertively, which makes it an ideal potted medicinal (the container reins it in). It favors moist, rich soil and is partial to light shade. If you have this kind of habitat, I DON’T recommend planting jiaogulan in the ground, as it can completely overtake an area and be almost impossible to control!

You’ll notice a distinct thinning and yellowing of the leaves if the plant is receiving too much sun. A porch or patio with dappled shade is a perfect niche for jiaogulan. Bring indoors once the weather starts to cool.

Safety and Contraindications: Do not use in pregnancy. Can cause nausea in larger doses or with sensitive individuals. Use caution when combining with blood pressure or blood thinning medications.

Lavender (Lavandula spp.)

Lavender (Lavandula spp.)

5. Lavender (Lavandula spp., Lamiaceae)

Parts Used: Above ground parts in flower, or flowers

Medicinal Preparations: Tea, tincture, infused oil, essential oil, sachet

Herbal Actions:

  • Relaxing nervine
  • Gentle sedative
  • Anxiolytic (relieves anxiety)
  • Antidepressant
  • Carminative (relieves gas and bloating)
  • Antimicrobial
  • Analgesic
  • Bitter

Medicinal Uses: Lavender has a wonderful proclivity for soothing the nerves, and has been used medicinally for centuries as a remedy for digestive issues, headaches, stress, and grief. It is a gentle sedative, which also makes it beneficial for anxiety and insomnia.

Lavender is often used in formula for the herbal treatment of depression as it has more immediate effects as compared to many of the slower-acting tonic antidepressants and adaptogens. I combine lavender with lemon balm (Melissa officinalis) and lemon verbena (Aloysia citrodora) in tea to help lift the spirits.

The flavor of lavender tea is stronger than one might expect: it’s slightly bitter, mildly astringent, and very aromatic. A little goes a long way. Try combining it with rose petals (Rosa spp.), mint (Mentha spp.), chamomile (Matricaria recutita), or passionflower (Passiflora incarnata) for relaxation and decompression. It is generally safe for children and the elderly.

Topically, lavender (as a wash or essential oil) can be healing for burns, wounds, and minor infections. It is soothing, antimicrobial, and pain-relieving.

Don’t forget that lavender is also a culinary herb! Find our recipe for decadent Lavender Truffles on the blog.

Cultivation: Lavender’s beautiful purple spikes and uplifting aroma make it a classic garden darling. English lavender (Lavandula angustifolia) is the most common species grown and used medicinally. However, there are thirty-nine species of lavender, many of which are grown ornamentally! Ask your local herb nursery which varieties or cultivars grow best in your area.

A short-lived perennial, lavender prefers full sun, well-drained soil, and ample airflow. You may want to add perlite, gravel, or sand to lavender’s potting soil to provide ideal growing conditions. And if you live in a region with high rainfall, consider giving the plants cover in a sunny locale so they don’t receive too much water. Bring your lavender plants inside to overwinter—preferably in a place that receives bright, direct light—if your climate experiences hard freezes!

Safety and Contraindications: There are no known safety precautions for lavender, although its tonic use may be constitutionally inappropriate. For example, if you have very dry skin and mucous membranes, the long-term internal use of lavender may be too drying.

Tulsi (Ocimum tenuiflorum) in the rear, spilanthes (Acmella oleracea) in the foreground, lavender (Lavandula spp.) plants on the right

6. Tulsi (Ocimum tenuiflorum, Lamiaceae)

Parts Used: Leaves and flowers

Medicinal Preparations: Infusion, tincture, pesto, medicated ghee, infused oil, infused vinegar, compress, and poultice

Herbal Actions:

  • Adaptogen
  • Antioxidant
  • Antidepressant
  • Anxiolytic (anti-anxiety)
  • Immunomodulator
  • Anticatarrhal (dispels phlegm and mucus)
  • Hypotensive (lowers blood pressure)
  • Hypocholesterolemic (lowers cholesterol)

Medicinal Uses: Tulsi, also known as holy basil, is Sanskrit for “the incomparable one.” It is a sacred folk herb in much of the Eastern world, and has quickly been adopted into the repertoire of Western herbalists, whose understanding of the plant originated with its traditional uses in southern Asia and northern Africa.

Tulsi is highly aromatic, antimicrobial, and adaptogenic; the leaves and flowers are used as a medicinal tea for colds, coughs, asthma, bronchitis, sinusitis, headaches, arthritis, stress, and anxiety.

Tulsi helps increase focus and clarity, making it especially useful for elders with declining cognitive abilities, children and adults with ADHD, and enterprising college students.

It can be combined with gotu kola (Centella asiatica), calamus (Acorus calamus), and rosemary (Rosmarinus officinalis) in formulas to increase concentration and cognition. Holy basil is a fine ally for people who are naturally scattered or distracted, as it is both calming and centering.

Cultivation: Holy basil may appear puny when you first plant it, leaving you to wonder if it has some botanical failure-to-thrive syndrome— perhaps you spoke too harshly with it when you were transplanting it.

Take heart in knowing when the days grow longer and the nighttime temperatures warm, it will take off!

Tulsi enjoys full sun in temperate areas, but doesn’t mind a little afternoon shade in warmer climates. It will grow in most any soil, but will thrive more lushly with good fertility and consistent moisture.

As with culinary basil, pinching back the shoots and early flowers encourages the plant to bush out and promotes more vegetative growth. Tulsi truly is an early bloomer, sometimes flowering when it is only a few inches high! Pinching off those early flowers helps it to develop into a well-rounded plant with lush foliage.

Several harvests can be obtained in one year: simply cut back the mature plant to eight inches or so, and it will re-grow quickly.

There are at least five varieties of tulsi. Tropical gardeners can grow all of them with success, and most varieties will reach waist-high proportions as woody perennials. Four-season herb growers can experiment with the tropical varieties as annuals or potted herbs that are brought indoors to overwinter, but the easiest to grow variety is the temperate holy basil. It germinates readily and self-sows, giving you a hearty supply of tulsi for years to come. For the largest variety of holy basil seeds, please see Strictly Medicinal Seeds.

Safety and Contraindications: Avoid in pregnancy or if trying to conceive. There is some controversy around the use of holy basil in pregnancy, but it has been used traditionally as an abortifacient and antifertility herb in some cultures.6

Holy basil may modify blood sugar regulation—people with diabetes should monitor blood sugar closely and talk to their physician prior to use.7

Several studies on male animals have shown a decrease in sperm count and motility and decreased mounting time (lower sexual behavior score) with extremely high doses (relative to body weight).8 It’s not clear whether this has any bearing on human physiology with moderate consumption.

Lemongrass (Cymbopogon citratus) growing with artichoke and sage

Lemongrass (Cymbopogon citratus) growing with artichoke and sage

7. Lemongrass (Cymbopogon citratus , Poaceae)

Parts Used: Stems and leaves

Medicinal Preparations: Tea, broth, honey, soup

Herbal Actions:

  • Nervine
  • Carminative
  • Diaphoretic
  • Antibacterial
  • Antifungal
  • Expectorant

Medicinal Uses: Throughout the world, lemongrass is a popular tea and everyday home remedy for some of the most common health complaints: headaches, stress, anxiety, indigestion, insomnia, coughs, colds, and flu.

It is a staple herb in Brazilian, Caribbean, Chinese, and Indian folk medicines. Much of the contemporary research conducted on lemongrass has centered on the essential oil, which has demonstrated marked antibacterial and antifungal properties.

I use lemongrass as a uniquely delicious medicinal tea. In the summertime, try pairing lemongrass with other citrusy herbs, like lemon balm and lemon verbena, along with hibiscus (Hibiscus sabdariffa), for a refreshing herbal iced tea.

You can add the flavorful “bulbs”—the tender inner base of the stems—to broths, Thai coconut soups, and curries. Teas and broths featuring lemongrass are wonderful for easing the symptoms of colds and flu. 

Cultivation: This aromatic tropical grass is often grown as a container plant and brought indoors to be protected during the colder months. Growing it in a pot helps to keep its size manageable, and it’s quite commanding when planted with other ornamental herbs, such as artichoke (Cynara scolymus) and purple sage (Salvia officinalis ‘Purpurascens’).

For a tropical flair, pair with nasturtium (Tropaeolum spp.) and other cascading flowers. Plan to acquire a large pot for lemongrass and its companions!

Lemongrass prefers full sun and soils that drain rapidly—consider adding extra perlite or pine bark fines to your soil mix. Harvest the stems repeatedly throughout the growing season to increase yields and to keep growth in check.

If you have difficulty finding lemongrass starts in your area, you can often obtain pieces of lemongrass stem, with attached roots, from Asian grocers. These can be directly planted in pots or encouraged to root in a glass of water before planting. You can also grow it from seed if you get a head start on the season.

Safety and Contraindications: Individuals who have reacted to lemongrass essential oil may develop an allergic contact dermatitis handling the fresh plant. The essential oil must be properly diluted before coming in contact with the skin.

White Sage (Salvia apiana)

White Sage (Salvia apiana)

8. White Sage (Salvia apiana, Lamiaceae)

Parts Used: Leaves and stems

Medicinal Preparations: Tea, tincture, aromatic smoke, honey, gargle, and steam inhalation

Herbal Actions: 

  • Antibacterial
  • Antifungal
  • Astringent
  • Carminative (lessens intestinal gas)
  • Anti-inflammatory

Medicinal Uses: White sage’s medicinal uses are nearly interchangeable with its Mediterranean cousin, garden sage (Salvia officinalis), although the former is more antimicrobial and stimulating than its domestic brethren.

I use a steam inhalation of the leaves to help break up respiratory congestion in both the lungs and sinuses. Try combining it with thyme (Thymus vulgaris) and wild bergamot (Monarda fistulosa) in the steam pot with a few drops of eucalyptus (Eucalyptus globulus) essential oil.

The practice of burning white sage as an aromatic cleansing and purifying agent has been widely adopted by Westerners, to the demise of wild populations which have been overharvested, primarily for sale as “smudge sticks.”

Cultivation: Endemic to southern California and Baja California, white sage has become increasingly rare in its native habitat due to over-gathering. If you enjoy this herb, please consider growing your own supply. Do not gather or purchase wild-harvested white sage. We have a more detailed growing guide (plus recipes!) on the blog.

White sage favors warm, dry conditions. In humid climates, white sage will sometimes develop fungal diseases or rot. I cut off the afflicted area, and it will often make a comeback, but sometimes the whole plant up and dies. Subsequently, I plant more white sage than I ultimately need.

White sage is especially alluring in a terra-cotta or glazed blue ceramic pot. Add extra drainage material to the soil mix, such as coarse sand, perlite, or pine bark fines, and take care not to overwater. White sage is also prone to aphids; if it seems over wilty, look for the little green, red, or black insects on the undersides of the fresh growth. Use insecticidal soap as an organic pest control.

Try placing potted white sage in a covered spot that receives ample sunshine, but excludes rainfall (like the overhang of a roof). Overwinter in a greenhouse, or in a south-facing window.

Safety and Contraindications: Sage is a uterine stimulant and should not be used internally in large doses by pregnant women. In medicinal quantities, it can dry up the breast milk. White sage is also highly drying and can aggravate dry skin and sinuses. 

Calamus (Acorus americanus, syn. A. calamus var. americanus)

Calamus (Acorus americanus, syn. A. calamus var. americanus)

9. Calamus (Acorus americanus, syn. A. calamus var. americanus, Acoraceae)

Parts Used: Rhizomes (root-like subterranean stems)

Medicinal Preparations: Tincture, tea

Herbal Actions: 

  • Aromatic bitter
  • Carminative (lessens intestinal gas)
  • Circulatory stimulant
  • Anti-inflammatory
  • Decongestant
  • Rejuvenative

Medicinal Uses: Calamus is a warming, stimulating, and drying remedy and is thus used for cold, damp conditions, and stagnation. For instance, it’s a valuable remedy for digestive issues, menstrual cramps, and chronic sinus congestion.

Calamus is especially helpful for supporting a crisp, clear mind—it nurtures alertness and clarity, and is a treasured ally for those with foggy thinking or a tendency to mind-wander. Many students appreciate the root for augmenting focus while studying!

Calamus also acts as a circulatory stimulant for people who run cold in the winter. Combined with ginger (Zingiber officinale) and cinnamon (Cinnamomum verum), it makes a tasty tea, although those with a tender palate may find it too spicy.

The root is a classic remedy for allergies, acting as a decongestant and anti-inflammatory. I combine it with turmeric root (Curcuma longa) and goldenrod (Solidago spp.) to treat allergies acutely (right when symptoms are present).

A little goes a long way with calamus—its pronounced flavor and spiciness make it an ideal candidate for formulas. In other words, combine milder tasting medicinals with calamus in your teas and tincture combinations to offset its potency.

Cultivation: Calamus is a wetland herb, and therefore thrives in containers that can be kept consistently moist, such as a retired bathtub or a plastic pond liner. For this reason, take extra care to water the plants during dry spells.

In cooler climates, calamus is quite happy and tolerant of the sun; gardeners in warmer or arid climates will want to give the plants afternoon shade, in addition to extra watering, to help it tolerate the heat and dryness.

Calamus reproduces by rhizomes; after two years you can divide the plants and colonize new containers or keep the harvested roots for medicine.

When sourcing calamus plants, look for A. americanus specifically rather than A. calamus. They are closely related—in fact, it’s still debated whether they are distinct species. However, a difference in chromosome numbers means that A. americanus plants don’t produce a potentially toxic compound (beta-asarone), whereas A. calamus does.

Safety and Contraindications: Do not use in pregnancy. May cause vomiting in high doses and may aggravate heartburn.

Lemon verbena (Aloysia citriodora) and one of her admirers

Lemon verbena (Aloysia citriodora) and one of her admirers

10. Lemon verbena (Aloysia citriodora, Verbenaceae)

Parts Used: Leaves and flowers

Medicinal Preparations: Tea, honey, syrup, and vinegar

Herbal Actions: 

  • Hypnotic
  • Nervine
  • Antibacterial
  • Antiviral
  • Analgesic
  • Antidepressant

Medicinal Uses: Lemon verbena is a tropical, South American plant—and it is often a favorite among the lemony herbs for its crisp aroma and fine flavor. Lemon verbena is an uplifting remedy, and is useful for conjuring sunshine during the dreariness of gray winter days, as well as during dark nights of the soul.

It is simultaneously brightening and calming, and doesn’t induce lethargy in most people if they drink it throughout the day. It is safe for children and elders, and in the same league as chamomile (Matricaria recutita) and mint (Mentha spp.) in that it rarely has side effects and is an everyday beverage tea. I combine lemon verbena with catnip (Nepeta cataria) and chamomile as a gentle sedative for insomnia.

Lemon verbena is also useful in quieting nausea and can be mixed with ginger and catnip for this purpose. It is useful for motion sickness, as well as the queasiness brought on by various infectious illnesses.

Cultivation: This brightly-scented perennial bush thrives in fertile, well-drained soil in full sun. It is highly drought tolerant and does best if it dries out between waterings. Pinch back the growing tips to encourage bushiness; this is most important when the plants are seedlings. The plants are also prone to spider mites—telltale signs include mottled yellow leaves and fine cobwebs on the underside of the leaves. Treat organically with a spray of insecticidal soap.

Potted plants in all but the warmest climates should be pruned, then brought indoors for the duration of the winter. Planted into moist soil amended with sand, lemon verbena will happily hibernate in your basement or an unheated greenhouse (tucked in with a cozy mulching of straw) until warm weather arrives again. Be warned that the plant will lose all its leaves over winter. Be sure to water it infrequently throughout the winter, though, to keep the roots alive.

Safety and Contraindications: No known precautions.

Wild Foods Recipe Round-Up

Foraging seasonal wild foods is an exciting and nourishing way to celebrate the turnings of the year—one that connects us to our ancestral stories of sustenance. Each season offers something unique, perfectly timed to nourish the cycles of life.

This recipe round-up is a duet: we’ve included every wild foods recipe from our blog, plus we’ve added recipes from some of our favorite foraging foodies. There are bushels of fantastic wild foods recipes out there (both in cookbooks and online)—this is really just a nibble to get you inspired!

Please remember: foraging wild foods calls for a healthy dose of caution and a solid grasp on foraging ethics and etiquette. You can find a detailed guide to all of the above in our article on Sustainable and Safe Gathering Practices.

This article is a featurette on recipes; not on plant ID! Some of the links may include ID information, but many will not. You’ll want to find a couple field guides relevant to your region by searching our book list. Find a local foraging and/or plant identification teacher, if possible! Remember, there are deadly poisonous plants and mushrooms out there: one wrong move could be your last.

Have fun and be safe—which means being 110% sure of any plant’s identification before you sample or harvest.

Spring: Wild Greens Galore

The spring foraging season is all about the greens! Spring presents us with a cornucopia of delectable wild greens that are both abundant and off-the-charts nutritious. This is a traditional time to integrate wild green foods and juices into meals as a way to cleanse the body after a winter of heavier foods. Depending on your region, look for fresh greens like chickweed (Stellaria media), wintercress (Cardamine spp.), dandelion (Taraxacum officinale), daylily (Hemerocallis fulva), and stinging nettle (Urtica dioica) from January through May.

Daylily Greens Saute

Daylily Greens Garlic Butter Sauté

I anticipate the arrival of daylily greens every year in early spring! They’re fantastic cooked up with little more than butter, garlic, and salt. Note that some people have daylily allergies, so try a small portion the first time, prepared from cooked greens. (Raw daylily is more likely to cause a reaction.) Please read this article for ID tips as it’s easy to confuse many poisonous plants for daylily.

Pecan Feta Wild Greens Pesto

Whirl this pesto together with whatever array of greens is handy to you, and combine them with salty, savory additions like toasted pecans, feta cheese, and tahini. Perfect for keeping in the fridge as a snack; fancy enough to serve as an appetizer course at dinner.

Wild Greens Pâté

Herbal pâté is a thicker, creamier variation on pesto. Made with wild greens, this is one of my all-time favorite condiments (especially when stinging nettles are added to the mix!). I spoon it onto eggs, crackers, veggies, and grain dishes. You can also try this vegan version featuring black walnuts and nutritional yeast from our friend, Asia Suler, of One Willow Apothecaries.-

One of my favorite breakfast dishes—a heart-friendly, wild foods/herbal version of the classic toasted bagel. This recipe features violet (Viola spp.) leaves and flowers, plus chickweed greens—which are high in antioxidants, bioflavonoids, and soluble fiber.

Wild Grape Leaf Dolmas by Dina Falconi

I love spicing up traditional dishes with wild foods flair. These dolmas, wrapped up in tender wild grape leaves, are a popular finger food at my house. I especially like to mince dried wild fruits in with more savory ingredients.

Summer: Foraged Berries and Blossoms

Summer’s wild foods dishes are loaded with the antioxidant gifts of flowers, mushrooms, and berries. This is hands-down the most colorful season to bring foraged foods to the table. This is also a prime-time window for food and herb preservation. Dry, freeze, jam, ferment, and infuse your extra harvests—your pantry will be a wonder come winter.

Stuffed Daylily Blossoms

Stuffed Daylily Blossoms

These appetizer-sized blooms will likely be the most beautiful dish on any table you set. Colorful, tantalizing, and savory, few will be able to resist their novelty and floral allure. Daylily petals are lightly crunchy and succulent, which pairs well with the creamy filling in this recipe.

Cherry Chipotle Nopales Salsa

Cherry Chipotle Nopales Salsa

This sweet and savory salsa is high in bioflavonoids, with its array of vibrant rainbow colors. Nopales (Opuntia spp., Cactaceae) are an important medicine and traditional food in Mexico, Central America, and the Southwest.

Wild Fruit Ice Cream by Dina Falconi

Homemade ice cream has it all: high-quality creamy sweetness that you can tweak to suit any dietary preference. I personally like using raw cow’s milk (or coconut milk) and local honey when I churn up a batch. Dina’s recipe is perfect for any of summer’s wild berries.

Dark Magic Reishi Truffles by Asia Suler

These chocolate reishi (Ganoderma spp.) truffles are decadent AND loaded with antioxidant, adaptogenic medicine. Reishi mushrooms are gathered in the summer months, but can be dried and saved for making treats any time of the year.

Nettle Seed Salt by Rebecca Altman

I try to always have this condiment on hand. The simple combination of salt, seeds, and lemon is tasty and medicinal; nettle seeds nourish the adrenals and kidneys, and can impart a boost of energy (sans caffeine!).

Nasturtium & Sumac Hot Sauce by Gather Victoria

Any pantry benefits immensely from a good jar of hot sauce. Even if you yourself do not partake, you’ll be glad you prepared a batch the next time you host Taco Tuesday or set out fixings for the burrito bar.

Dandelion Flower Fritters by Mountain Rose Herbs

This is an old-time classic that every child will be excited to try! I like to serve piping hot dandelion (Taraxacum officinale) fritters alongside a homemade dipping sauce à la plain yogurt blended with lemon juice, garlic, and fresh herbs.

Spiced Hawthorn Persimmon Pear Brandy

Fall: Wildcrafted Comfort Foods & Drinks

Whereas summer’s harvest is bright and bold, I find the wild foods of fall to be softer, sweeter, and more earthy. This is the season for gathering ripening tree fruits, savory nut meats, edible roots, and sun-browned seeds. Again, this is an abundant time for putting up any foraged surplus to nourish you through the frosty months of winter.

Spiced Hawthorn Pear Persimmon Brandy

A warming, lightly boozy concoction that can be made alcohol-free by substituting apple cider for brandy. This beverage blends some of fall’s tastiest fruits and herbs into a cold season tonic that will have you feeling ready for crisp nights and wood stove fires.

Foraged Chai Masala by Ellen Zachos

This wild chai features spicebush (Lindera benzoin) and juniper (Juniperus spp.) berries, wild ginger roots (Asarum canadense), and spruce needles (Picea spp.). Local, regional, and domestic substitutions are 100% acceptable! According to its creator, this chai is “freakin’ amazing.”

Burdock Root Roast by Colleen Codekas

Burdock root (Arctium lappa, A. minus) is a classic food herb whose flavor is earthy and sweet—somewhat like a carrot or parsnip. This simple recipe really lets burdock shine. Consider switching out the olive oil for other fats that have a higher smoke point (like ghee or coconut oil), and adding more root veggies to the mix—I like carrots and sweet potatoes.

Raw Persimmon Pudding by Wild Abundance

This creamy, raw pudding is one of my favorite fall treats—and it’s so easy to whip up. Make sure the persimmons (Diospyros virginiana) you gather have sweetened up properly; they are extremely high in mouth-puckering tannins until well and fully ripe!

Chanterelle Stuffing with Pine Nuts by Hank Shaw

Stuffing is one of the most comforting foods to put on the table at special fall feasts. Add delicacies like chanterelles (Cantharellus cibarius) and pine nuts (Pinus spp.), and you’ve got a masterpiece!

Black Walnut Butter by Woodland Foods

If you’re willing to crack all the nuts needed for this recipe, you’re in for a treat (that’s rich in magnesium). The author doesn’t specify which plant oil to use—I prefer coconut.

winter

Winter: The Wild Feast Continues

Yes, there are wild foods to forage throughout the winter months! Admittedly, I tend to do more foraging in my pantry than in the hedgerows this time of year, but if you know what to look for, you’ll be impressed by the nourishment available during the cold moons. Rosehips (Rosa spp.), edible roots, seaweeds, certain mushrooms, hardy greens, and many conifer needles can be gathered through the hard frosts of winter.

Conifer & Wild Berry Winter Syrup by Gather Victoria

Nothing calls to mind the sweetness of winter like the comforting aroma of evergreens. Conifer needles can be stirred into a decadent spread of recipes, including this vitamin C-rich syrup. Take by the spoonful, or drizzle over yogurt or cream.

Sauerkraut with Juniper Berries by The Wondersmith

I consider sauerkraut to be a year-round staple, but I especially appreciate its probiotic benefits in winter when my diet tends to be heavier. Juniper “berries” (Juniperus spp.) are a traditional addition to krauts, and I love the piney flavor they impart. Gather in late fall to early winter—use fresh or dried.

Herbal Bone Broth by Ritual Kitchen

Another winter essential. Bone broth (or veggie broth) can be amped up with the addition of herbs. This recipe offers up plenty of possibilities, from nettles to rosehips to burdock roots.

Rose Hip & Cranberry Compote by Rosalee de la Forêt

Vitamin C is strengthening to the immune system, and this recipe is loaded with it! Take care with foraged rose hips: they need to be split and de-seeded before they can be eaten as food (tiny hairs that irritate the throat surround the seeds). They can be used whole when taken as tea.

Oyster Mushroom Udon Soup by Fat of the Land

Winter is soup season! Various species of oyster mushrooms (Pleurotus ostreatus) fruit throughout the year, and I’ve collected many nice harvests in the heart of winter. You can also rehydrate dried mushrooms for this recipe.

Homemade Maple Syrup by Wild Abundance

Maple syrup is made from the sap of sugar maple trees (Acer saccharum). Don’t have any near you? Other trees can be tapped, including hickory (Carya spp.), birch (Betula spp.), walnut (Juglans spp.), and other species of maple (Acer spp.).

The Best Herbal Immune Stimulants for Cold and Flu Season

Winter is rife with viral booby-traps—there’s a head cold and cough waiting at every gas station pump and pin pad across the land. A strong immune system is adept at navigating pathogenic obstacles, but some scenarios call for a boost, herbal-style. When I know I’ve been exposed to a cold or the flu, I don’t waste a moment in reaching for my tried-and-true immune stimulating herbs.

When to Use Immune Stimulants

Immune stimulants—also called immunostimulants—help the body to resist illness after being exposed to a pathogen and during the initial stages of an infection. Immunostimulants work through augmenting our bodies’ innate antimicrobial efforts, primarily through affecting white blood cell activity.

This class of herbs can also be called on to stimulate immune activity throughout the duration of an infectious illness, which ultimately can help a person get over the sickness more quickly. Consider calling on immunostimulants if you are:

  • Flying on an airplane
  • Caring for a sick family member
  • Attending a four-year old’s birthday party in January
  • Feeling the first signs of a cold
  • Fighting an infectious illness, like a cold or the flu

Immunostimulating herbs have an immediate but short-lived effect, and thus need to be re-administered frequently to maintain their effectiveness. In my experience, higher doses of these herbs are often needed to treat infection.

Foundational Self Care is Essential

Remember, herbs are handy allies, but it’s all too easy to “prop ourselves up” with immune stimulants while we continue to neglect the care of our body, emotions, or spirit. If we consistently ignore the basics of good sleep, nutrition, hydration, and lifestyle, we have missed the point.

See our in-depth article on Herbs for the Immune System for basic tips on staying healthy this winter. You’ll also find loads of essential information on the full spectrum of immune-boosting herbs, including immune tonics and herbal antimicrobials!

Also, check out our articles on Immune Tonics and Herbal Antimicrobials.

Play Smart, People

Please note that this article is introductory in scope and doesn’t fully cover each medicinal. If you plan to forage any of these herbs, you’ll need to seek out identification tips. You’ll also need to learn foraging ethics and guidance before you harvest any plant from the wild! There are deadly poisonous plants out there, so proper identification is paramount.

See our blog articles on Foraging and Wildcrafting for more guidance.

Safety First: Learn When to Seek Medical Care

Also, it’s important to realize that herbs aren’t always the only support you might need to combat infections. Antibiotics and conventional medical care have their place, especially with babies, young children, and elders, as well as in the case of serious infections. For a list of warning signs that indicate the need for medical care, please visit our comprehensive article on Herbs for the Immune System.

If you have an autoimmune condition, please be aware that immune-stimulating herbs have a potential to increase autoimmunity, although this is more the exception than the rule.

Spilanthes (Acmella oleracea)

Spilanthes (Acmella oleracea)

1. Spilanthes, Toothache Plant, or Paracress (Acmella oleracea, Asteraceae)

Parts Used: Leaves, stems, and flowers

Preparations: Tincture, tea, nibble

Herbal Actions:

  • Immunostimulant
  • Antimicrobial
  • Anti-inflammatory
  • Sialagogue (stimulates salivation)

Spilanthes has been one of my top ten herbal allies for the past two decades—I became a devotee the first year I began growing it and using it for medicine. Its leaves and gumdrop-shaped flowers can be called upon for a wide spectrum of infectious illnesses; including colds, flu, sinus infections, and ear infections. Clinical studies demonstrate that spilanthes has strong effects against pathogenic bacteria.

One of the most common ways I use spilanthes is to augment the body’s internal immune defenses. I typically combine it with other immune-stimulating herbs like echinacea (Echinacea purpurea) and honeysuckle (Lonicera japonica). At the first sign of an achy throat or the sniffles, I add spilanthes to homemade saline gargles and neti pot solutions, along with goldenseal (Hydrastis canadensis).

Remember that higher doses—to the tune of 3 to 4 droppersful of the tincture every few hours for the first day or two—are often necessary to fight infection and avoid antibiotic use. If an infection does take hold, I add other antimicrobial herbs like usnea (Usnea spp.), goldenseal (Hydrastis canadensis), and honeysuckle (Lonicera japonica) to the formula.

Be forewarned that the tincture and fresh plant will set your mouth to drool! Spilanthes is a traditional toothache remedy because of its antimicrobial, numbing, and stimulating qualities. Along with the stimulation of blood to the gums, the herb will also prompt copious salivation.

Precautions and Contraindications: Because spilanthes is in the aster family, it may cause a reaction in people who are highly sensitive to plants like ragweed and chamomile; this possibility is rare, but sensitive individuals should proceed with caution when taking spilanthes for the first time. Take care not to squirt the tincture on the back of your throat or chew too large a wad of spilanthes, as the throat may take offense and clamp down—not a fun exercise!

Echinacea (Echinacea purpurea)

Echinacea (Echinacea purpurea)

2. Echinacea (Echinacea purpurea; E. angustifolia, Asteraceae)

Parts Used: Roots, flowering tops, aboveground parts gathered in full bloom

Preparations: Tincture, decoction (roots), infusion (leaves and flowers)

Herbal Actions:

  • Immunostimulant
  • Antimicrobial
  • Anti-inflammatory
  • Anticatarrhal (decongestant)
  • Lymphagogue
  • Sialagogue (stimulates salivation)
  • Alterative

The roots, seeds and fresh flowers of echinacea are all medicinal and make a tingly tasting, immune-stimulating tea or tincture. Echinacea can be used to fight any infection in the body, but is particularly effective against infections of the upper respiratory tract. I use it as a short-term remedy for warding off colds and flu. Studies show that echinacea is safe and effective against the common cold and that it is protective against lowered immunity due to stress.

Herbalist Rosemary Gladstar reminds us that echinacea is both “preventative and curative.”1Unfortunately, many people stop taking it once they are sick, thinking it can’t help them anymore. However, echinacea stimulates many aspects of our immune system to fight infection more quickly and continues to be an important ally even once we become ill. I often combine it with spilanthes (Acmella oleracea) to round out its immunostimulating qualities.

Echinacea is readily available anywhere herbal teas and tinctures are sold. Please only buy the cultivated root, as several echinacea species have been over-harvested from the wild. If you make your own medicines, I recommend using freshly harvested echinacea from the garden rather than dried, as I find the fresh preparations to be more potent. I like to combine the root tincture with the seed tincture in equal parts.

Contraindications: Echinacea is not recommended for continuous use as a tonic during the cold and flu season. Instead, use immune tonics, like the ones outlined in this article. Use caution when ingesting the fresh juice or tincture, as it can irritate the throat to the point of decreased airflow. This appears to be idiosyncratic, but I have seen it a few times, so it warrants mentioning. Dilute the medicine and avoid letting it contact the back of the throat. Those with Asteraceae allergies may experience side effects; however, such reports are extremely rare.

Japanese honeysuckle (Lonicera japonica)

Japanese honeysuckle (Lonicera japonica)

3. Japanese honeysuckle (Lonicera japonica, Caprifoliaceae)

Parts Used: Floral buds, opened flowers, stems, and leaves

Preparations: Tincture, decoction, infusion, honey, syrup, poultice, douche, and compress

Herbal Actions:

  • Immunostimulant
  • Antiviral
  • Antibacterial
  • Anticatarrhal (decongestant)
  • Expectorant
  • Anti-inflammatory
  • Astringent
  • Diuretic
  • Antioxidant

I use Japanese honeysuckle flowers to address hot, inflamed conditions like head colds and the flu, as well as a range of related infections—laryngitis, sinusitis, tonsillitis, pneumonia, bronchitis, croup, and whooping cough. The fresh blooms are powerfully antimicrobial, cooling, and anti-inflammatory—making them specific for malaise and feverish conditions.

They are one of the most widely used medicinal herbs in the world, especially in China where the herb is extremely popular, both with trained herbalists and as an over-the-counter herbal medicine. Japanese honeysuckle’s popularity amongst western herbalists primarily comes from being inspired by traditional Chinese herbalists.

For a scientific review of Japanese honeysuckle’s antimicrobial benefits, visit this link.

Japanese honeysuckle is a common invasive plant here in North America, but you won’t find its medicine readily available in commerce except in establishments that sell Chinese medicine. Thus, you’ll likely need to harvest your own. The flowers can be gathered as buds and as opened blooms, and tinctured fresh in alcohol. In Chinese medicine, the buds are considered to be the most potent, but I find the buds and the freshly-opened flowers to be similar medicinally. Honeysuckle is also effective as a tea; I combine it with mint (Mentha spp.) and lemon balm (Melissa officinalis) to mask its slight bitterness.

I would venture that most of you are intimately acquainted with the blooms of this memorable vine and have partaken of her nectar. All you sucklers will be happy to know that the familiar honeysuckle of your childhood is the very same potent medicinal we’re discussing here.

Many species of honeysuckle have been used medicinally throughout North America, Europe, and Asia. However, their traditional use and the part employed (bark, leaves, flowers, etc.) varies among species; the biochemistry of the genus is also variable. For example, some honeysuckles have poisonous berries, and some have leaves and bark that can cause vomiting and diarrhea.

Subsequently, we can’t make broad speculations about the medicinal qualities of the entire genus. We’re only talking about Japanese honeysuckle in this article—don’t extrapolate the information here to all honeysuckle species!

You can’t free it up with the honeysuckles, no matter how fun that sounds!

Japanese Honeysuckle (Lonicera japonica) blooms

Japanese Honeysuckle blooms (Lonicera japonica)

Japanese honeysuckle is native to eastern Asia. It has spread throughout much of the world and can now be found in South America, North America, Oceania, and Europe. In the United States, it is especially prolific in the Southeast, but can be found in almost every state, including Hawaii. Do not plant Japanese honeysuckle as it’s seriously invasive. Harvesting it for medicine is one way to slow its spread!

Japanese honeysuckle is a perennial woody vine that twines around its host, reaching 30 feet (9 m) in length. It can be found in thickets, pastures, and young, open forests and along fencerows, roadsides, and the forest’s edge. It is not a shrub, unlike many other honeysuckle species.

The leaves are elliptical to oblong and leathery when mature (they feel thickish); they are opposite. The leaves grow to 1.2–3 inches (3-7.5 cm) long and have ciliate margins (tiny hairs, like cilia, growing from the edge of the leaf). The vine has peeling, brown bark.

Here are some resources to help you properly identify Japanese honeysuckle:

Contraindications:  Some species have been used to stimulate the menses and childbirth, so I would avoid the internal use of honeysuckle in pregnancy to be on the safe side. Make sure to only gather this species; other honeysuckles are not necessarily safe or used medicinally in the same fashion. The berries are poisonous.

Prickly Ash, Toothache Tree, or Hercules’ Club (Zanthoxylum clava-herculis, Z. americanum, Rutaceae)

Prickly Ash, Toothache Tree, or Hercules’ Club (Zanthoxylum clava-herculis, Z. americanum)

4. Prickly Ash, Toothache Tree, or Hercules’ Club (Zanthoxylum clava-herculis, Z. americanum, Rutaceae)

Parts Used: Bark and berries

Preparations: Tincture, decoction

Herbal Actions: 

  • Immunostimulant
  • Lymphagogue
  • Antimicrobial
  • Diaphoretic
  • Circulatory stimulant
  • Sialagogue (stimulates salivation)
  • Antirheumatic
  • Astringent
  • Antibacterial
  • Antiprotozoal

Prickly ash may be less familiar to you than the other herbs featured in this article, yet it’s one of our finest lymphatic herbs, immune stimulants, and circulatory stimulants.

Prickly ash’s name is derived from its leaf arrangement bearing a loose resemblance to the unrelated ash tree (Fraxinus spp.) and its formidable thorns, found along its branches and trunk. The tree’s fearsome armament inspired its alternate name, Hercules’ club. (Note: the common name Hercules’ club is also used for the unrelated Aralia spinosa.)

When I was in college one of my botany professors pulled a prank on me in front of my classmates. He invited us to try some of the tree’s fruits, and being an adventurous fledgling herbalist, I gamely chewed on a handful.

Immediately, my mouth became tingly and numb. I began drooling, bent over in an attractive spit-hunch to release the flood of saliva upon the ground. That experience was an unforgettable introduction into the profound physiological effect of alkamides, immune-stimulating and saliva-inducing compounds that are also shared by echinacea and spilanthes. This distinct mouth-numbing quality prompted yet another common name  toothache tree.

Prickly ash’s yellow bark played prominently into the materia medica of Native Americans and subsequently the European settlers, due to its wide medicinal applications, including powerful antimicrobial qualities. The bark is colored yellow by a potent antimicrobial alkaloid, berberine, which is also found in goldenseal (Hydrastis canadensis), barberry (Berberis, multiple species) and Oregon grape root (Mahonia, multiple species).

The tea and tincture of the bark are used in a similar fashion. Be warned that the tea is tingly and strong tasting. Many herbalists put a small amount of prickly ash in their herbal combinations as an adjuvant—an herb that directs, or orchestrates, the actions of the other herbs in a formula. Think: botanical rabble-rouser.

Prickly Ash (Zanthoxylum clava-herculis, Z. americanum)

Prickly Ash (Zanthoxylum clava-herculis, Z. americanum)

Prickly ash bark is taken in small amounts tonically to move the lymphatic system, innervate the immune system and stimulate circulation. In larger amounts, it is used to treat varied acute digestive issues, and is especially helpful in treating transient, foodborne gastric infections.

Toothache tree can be used to numb the gums in dental infections, and also offers antibacterial assistance. The bark can be used topically—chew on twigs or brush with the powder daily to improve gum health in periodontal disease. Toothache tree’s oral benefits stem from increased circulation and tightening loose gums, as well as its antimicrobial qualities.

Various species in the Zanthoxylum genus produce spicy fruits called Szechuan pepper, a pungent spice used in Asian cuisine, notably Chinese five-spice powder.  Many other species are used medicinally in India, China, Korea and Japan. Both Z. americanum and Z. clava-herculis are considered interchangeable medicinally.

Contraindications: Prickly ash may affect anticoagulant therapythis precaution is based on studies with animals using isolated constituents; the herb hasn’t been studied on humans in this capacity. Accordingly, proceed with caution if taking blood thinners. Prickly ash shouldn’t be used in pregnancy.

Garlic (Allium sativum)

Garlic (Allium sativum)

5. Garlic (Allium sativum, Amaryllidaceae)

Parts Used: Bulb

Preparations: Raw, tincture, fire cider and other infused vinegars, honey, oil

Herbal Actions:

  • Immunostimulant
  • Immune tonic
  • Antimicrobial
  • Diaphoretic
  • Hypotensive (lowers blood pressure)

Herbalist David Hoffman writes that: “Used daily, garlic aids and supports the body in ways that no other herb can match.”2Among its many gifts, garlic is one of our finest remedies for supporting immune health—it’s an essential staple in my kitchen as a potent immune stimulant and antimicrobial herb (it both kills pathogens and boosts immunity).

It can be highly effective in preventing infections such as the common cold and flu, as well as combating pathogens if an illness takes hold. Clinical studies support the ancient folk wisdom that garlic does indeed activate the immune system.

Pungent and warming, garlic helps to break up mucus in the body; it’s specifically beneficial for respiratory congestion. Raw garlic is the most effective preparation for avoiding and treating acute infections. Crush or chop a clove and allow it to “wilt” by leaving it alone on the cutting board for 10-15 minutes. Then add to honey, oil*, soup, vinegar, or tea.

Garlic scapes (Allium sativum)

Garlic scapes (Allium sativum)

Garlic is metabolized via the bloodstream, so applying garlic oil to the bottoms of the feet is an effective way to get its medicine flowing through the body (an especially great application for kiddos!).

Garlic doubles as an immune tonic, which means that it can be taken regularly to bolster the immune system over time. One clove per day, minced and added to food raw, is optimal.

My favorite garlicky preparation is fire cider—a sweet and spicy tonic made with apple cider vinegar. I recommend trying our rich red recipe for Hibiscus Pomegranate Fire Cider. I like spooning it over salads, and always take a tablespoon or two when I feel a sore throat or runny nose coming on.

Contraindications: Garlic can aggravate heartburn and gas, especially if ingested raw or in large quantities. It can also aggravate peptic ulcers. Coating garlic with olive oil or preparing it in an oil-based sauce helps minimize these effects. Avoid high doses of raw garlic one week before surgery due to its blood-thinning qualities. If taking blood thinners, consult a cardiologist before taking high doses of raw garlic. *Note that garlic preserved in oil can create a perfect breeding ground for botulism. Garlic-infused oil should be used fresh, or kept in the refrigerator and used within a few days.

The cold months of the year bring a flurry of beastly germs to our doorstep. These wee-but-wicked pathogens must sense that our immune systems are vulnerable—especially during the holidays when rich food and drink prevail. I like to start bolstering my family’s immune systems early in the cold & flu season; well before everyone around us is sniffling and sneezing. Practices like eating a nourishing diet; getting plenty of sleep, sunshine, and water; and proper hand washing are essential, but I also rely on a handful of tonic herbs to keep us healthy and resilient.

Herbal immune tonics are traditionally taken on a daily basis during the fall and winter months to strengthen immunity and lessen our chances of succumbing to common viral infections. These herbs are slow-acting with a prolonged effect, so they must be taken regularly to be beneficial. They differ from immunostimulating herbs (also known as immune stimulants) like echinacea (Echinacea purpurea) and spilanthes (Acmella oleracea), which are taken right at the onset of an illness for on-the-spot protection.

Therapeutically, immune tonics are also used to address poor immune resilience—for example, individuals who experience frequent infections—and to boost the immune system in preparation for cold and flu season. You’ll notice that two of the remedies we feature in this article are mushrooms: reishi and turkey tail. This is no coincidencemany of our premiere immune tonics are fungi. We use the term “herb” loosely here at the Chestnut School to include therapeutic medicinal trees, shrubs, herbaceous plants, and mushrooms.

Most immune tonics fall into the category of immunomodulators, which are herbs that have balancing, or amphoteric, effects on the immune system (making them more appropriate, in general,  for folks with autoimmune conditions, as compared to immunostimulating herbs). You can read more about both immunomodulators and immunostimulants in our in-depth article on Herbs for the Immune System.

Please note that this article is introductory in scope and doesn’t fully cover each medicinal. If you plan to forage any of these herbs, you’ll need to seek out trustworthy identification tips. You’ll also need to learn foraging ethics before you harvest any plant from the wild! There are deadly poisonous plants and mushrooms out there, so proper identification is paramount. See our Foraging and Wildcrafting resources on the blog for more guidance.

Before we dive into the herbs and mushrooms, we’d like to share a reminder that a healthy lifestyle is the best immune booster! Herbs are excellent supporting players, but we can’t rely upon them to be the only stars in the show. To read up on our suggestions for holistic immune health, visit our comprehensive article on Herbs for the Immune System.

Hemlock reishi (Ganoderma tsugae)

Five Luminary Medicinals to Boost Immunity

1. Reishi (Ganoderma tsugae, G. lucidum, G. curtisii, G. martinicense, Ganodermataceae)

Parts Used: Mushroom fruiting body

Preparations: Long decoction, syrup, preserved concoction

Herbal Actions:

  • Immune tonic
  • Immunomodulator
  • Antiviral
  • Antibacterial
  • Adaptogen
  • Anti-inflammatory
  • Antioxidant
  • Anti-anxiety
  • Cardiotonic
  • Hepatic

Known as the ‘mushroom of immortality’, reishi is an herbal immune tonic and immunomodulator. Taken regularly, it can enhance and fine-tune the body’s immune response. It’s especially helpful as a daily remedy for those who have weak lungs or who frequently succumb to respiratory infections. It strengthens the circulatory system and is a legendary adaptogen, making it a supreme ally for increasing overall resilience. Reishi is also a traditional tonic for anxiety and can help impart calmness in a slow and sustained manner.

Reishi is better prepared as a tea than a tincture, as some of its medicinal properties are destroyed by high percentages of alcohol. Simmer the mushrooms for a few hours to fully extract its polysaccharide compounds, which are the active immunomodulating compounds.  Its flavor is slightly bitter, so I like combining it with pleasant-tasting herbs like astragalus (Astragalus propinquus), licorice (Glycyrrhiza glabra)*, and cinnamon (Cinnamomum verum) —it’s particularly delicious in herbal chai blends. I also add a handful or two of dried reishi slices to bone or vegetable broth when I have a pot simmering.

Hemlock reishi mushroom (Ganoderma tsugae)

Reishi can be purchased online or at local health food stores, cultivated at home, or gathered from the wild. There are a number of medicinal species in the genus. We use our local hemlock reishi (Ganoderma tsugae) and artist’s conk (Ganoderma applanatum). If you’d like to try foraging this mushroom, please research which Ganoderma species grows near you—and if they’ve been used medicinally—along with  referencing a good mushroom field guide or reliable online source (I always cross-reference sources when using the internet). Here are a couple online resources to get you started:

Contraindications: Use cautiously with blood-thinning medication. Avoid if you have mushroom allergies.

*Avoid licorice if you have high blood pressure, edema, or a cardiac condition.

Elderberry honey

2. Elderberry (Sambucus nigra var. canadensis and S. nigra, Adoxaceae)

Parts Used: Berries and flowers

Preparations: Syrup, tincture, infusion (flowers), decoction (berries), infused honey

Herbal Actions:

    • Berries:
      • Immune stimulant
      • Immune tonic
      • Antibacterial
      • Antiviral
      • Antioxidant
      • Diaphoretic
      • Anticatarrhal (decongestant)
      • Anti-inflammatory
    • Flowers:
      • Immune tonic
      • Antiviral
      • Anti-inflammatory
      • Diaphoretic
      • Anticatarrhal (decongestant)
      • Astringent

The berries of elder are one of our most treasured immune tonics—they are effective, nourishing, and delicious when prepared as a dark purple syrup. Taken daily throughout the fall and winter, elderberry offers us protection against colds, flu, and other viral infections. One study demonstrated elderberry’s antimicrobial effects against two strains of the influenza virus and several bacteria that are commonly responsible for secondary, or concomitant,  sinus infections with the flu.

And in the case of an illness, elderberry is immune stimulating, diaphoretic (helps to break a fever), and anticatarrhal (decreases mucus in the respiratory passages). Studies show a lessening in the duration and severity of cold symptoms as well as the flu.

I prepare elderberry syrup by combining equal parts elderberry tincture, elderberry tea, and elderberry-infused honey. Children love this remedy, which can be made alcohol-free if you prefer (you can substitute a vinegar extraction for the alcohol-based tincture). Doses can be liberal (by the tablespoon), several times per day. Do not give elderberry honey or syrup containing the honey to babies younger than one-year-old.

Elderflower (Sambucus nigra var. canadensis)

Elder flowers also demonstrate strong antiviral activity against influenza, and can be integrated into your elderberry syrup along with other immune-boosting herbs like cinnamon (Cinnamomum verum) and ginger (Zingiber officinale). Curious to see a step-by-step demonstration on making herbal syrups? Visit our video tutorial and download our syrup guide!

Dried elderberries can be purchased online from sources like Mountain Rose Herbs, and fresh, frozen elderberries can be purchased from organic farms (you’ll need to do an online search for these). However, elder is also a classic garden-grown medicinal and forageable herb. If you plan to forage elder from the wild, you will need to do some serious botanical detective work. There are several deadly poisonous look-alikes, including water hemlock (Cicuta spp.).

I highly recommend reading Sam Thayer’s write-up on elderberry and its look-alikes in his book, Nature's Garden: A Guide to Identifying, Harvesting, and Preparing Edible Wild Plants. You can also reference this online resource for identification tips:

Contraindications: Eating raw (uncooked or untinctured) elderberries can cause nausea, vomiting, and/or diarrhea in many people. Once the plant has been purged from the system, there is no lasting illness. In general, we suggest starting with small doses and working your way up to assess tolerance. The flowers, tea, tincture, syrup, and cooked berries are unlikely to cause any side effects.

3. Garlic (Allium sativum, Amaryllidaceae)

Parts Used: Bulb

Preparations: Raw, tincture, fire cider and other infused vinegars, honey

Herbal Actions:

      • Immune tonic
      • Immune stimulant
      • Antimicrobial
      • Diaphoretic
      • Hypotensive (lowers blood pressure)
      • Anticatarrhal (decongestant)

This beloved spice has been used medicinally for over 5,000 years; one of the first accounts of its use was to sustain the health of the Egyptian laborers who built the pyramids.1 Later, it was a powerful field remedy in World War I, saving thousands of lives and limbs through its infection-fighting capabilities.2

Garlic is an essential staple in my kitchen as a potent immune system tonic and antimicrobial herb. It can be highly effective in preventing infections such as the common cold and flu, as well as infections of the digestive tract. The volatile oils in garlic are excreted through the lungs, making it especially beneficial for infections of the respiratory system. One randomized controlled study showed that garlic reduced the incidence of common cold. Here’s a review of garlic’s demonstrated activity against various pathogenic bacteria, fungi, and protozoans.

A bouquet of garlic scapes

Our family prepares a special garlic sauce every week made of raw garlic, extra-virgin olive oil, sea salt, and nutritional yeast. The sauce goes on avocado toast, eggs, pasta, chili, soup, baked potatoes, you name it. We keep it in the refrigerator (important, as garlic oil can harbor botulism and has made people sick) and literally pull it out at every meal. Our family of three goes through a quart a week and we rarely catch colds.

Garlic is easy to add to the diet as a culinary herb, and I always save my garlic skins to toss into broths. The suggested daily dosage is one clove per day, added to food. My favorite garlicky preparation is fire cider—a sweet and spicy tonic made with apple cider vinegar. I recommend trying our ruby-red recipe for Hibiscus Pomegranate Fire Cider. To fully capitalize on garlic’s antimicrobial and blood thinning qualities, it should be eaten raw.

Contraindications: Garlic can aggravate heartburn and gas, especially if ingested raw or in large quantities. It can also aggravate peptic ulcers. Coating garlic with olive oil or preparing it in an oil-based sauce helps minimize these effects. Avoid high doses of raw garlic one week before surgery due to its blood-thinning qualities. If taking blood thinners, consult a cardiologist before taking high doses of raw garlic.

Astragalus pressed roots

4. Astragalus (Astragalus propinquus, Fabaceae [formerly Astragalus membranaceus])

Parts Used: Root

Preparations: Decoction, powder, soup and stew stock, goo balls

Herbal Actions: 

      • Immune tonic
      • Immunomodulator
      • Antiviral
      • Antibacterial
      • Adaptogen
      • Antioxidant
      • Cardiotonic
      • Hepatic

Astragalus has become a renowned tonic in Western herbalism over the past two decades, primarily for its adaptogenic and tonic immune qualities. Scientific studies demonstrate that astragalus regulates white blood cell (immune cell) activity and stimulates our natural killer cells (NK cells)  to present a strong front against pathogens. Astragalus has also demonstrated increased interferon production (an antiviral and immune-signaling agent produced by the body).3

Astragalus is best used as a daily remedy to build immune strength—its medicine is slow and sustained, with full benefits reached after weeks of daily ingestion. In Traditional Chinese Medicine, astragalus augments the Wei Qi, which can be likened to a protective sphere, shielding the body from harmful external pathogens.

Astragalus, or Huang qi (Astragalus propinquus)

Because astragalus is a food herb, it’s safe to take relatively large amounts regularly. I love adding a handful to broth, integrating the fine-flavored root into herbal chai, and mixing the powder into goo balls, cookies, and other treats. Tincture is not recommended because alcohol doesn’t optimally extract astragalus’ immune-enhancing polysaccharides. These polysaccharides are water soluble and more readily extracted with prolonged decoctions or simmering.

Astragalus root has a sweet, beany flavor (it is in the legume, or bean, family, after all), making it easy to sneak into the diets of picky eaters, including kids. Toss a few of the pressed roots (these look like tongue depressors, and are pictured above) into any simmering stew, soup, or sauce, and it will impart only the tiniest of flavor imprints! The roots can be pulled out of the dish, much as you would pull out a bay leaf, right before serving.

Contraindications: Because astragalus stimulates immune activity, it could potentially weaken the effects of immunosuppressive pharmaceuticals, such as cyclosporine and corticosteroids. This adverse reaction is theoretical in humans but has been verified in animal studies.4 In high doses (30 grams or more) and via injection, astragalus has caused itching and allergic skin reactions. Symptoms of overdose may include headaches, insomnia, dizziness, hot flashes, and hypertension.

Fresh turkey tail

5. Turkey Tail (Trametes versicolor, Polyporaceae)

Parts Used: Mushroom fruiting body

Preparations: Long decoction, soup stock

Herbal Actions:

    • Immune tonic
    • Immune stimulant
    • Antiviral
    • Antitumor
    • Antioxidant

Turkey tail is a medicinal mushroom and immune tonic par excellence, with significant antiviral and immune-balancing qualities.5It’s beneficial for anyone who wants to prime their immune system, but especially for those who experience general immune weakness or frequent upper respiratory infections. In addition to boosting immunity, some herbalists believe turkey tail enhances the effects of antimicrobial herbs.6Turkey tail is a foundational herb for supporting the immune system in alternative cancer therapy and prevention.7

Like other medicinal mushrooms, turkey tail is best taken as a decoction or added to broth blends. Again, this is a perfect time to incorporate the warming flavors of chai. Turkey tail is mildly bitter—combine it with other medicinal mushrooms that are pleasant in flavor, such as shiitake (Lentinula edodes), maitake (Grifola frondosa), or lion’s mane (Hericium erinaceus).

I make an herbal broth over the winter that contains astragalus, reishi (just a little, so it’s not too bitter), shiitake, turkey tail, calendula (Calendula officinalis), and seaweed. We add the broth to soups, stews, and marinades, and my picky daughter doesn’t notice the herbal flavor.  However, her immune system certainly takes note!

Turkey tail mushrooms

Turkey tail is one of the most common woodland mushrooms in the world—it’s likely growing near you! It can be found exclusively on dead hardwood trees, stumps, and branches (and sometimes on dead conifers).

Turkey tail does have some look-alikes, and proper identification is essential. That being said, many people successfully learn to know and recognize turkey tail. Its fruiting body is fan-shaped—bearing a likeness to a turkey’s opened tail feathers—with colored bands of blue, brown, red, gray, and white. Its undersides are white or tan in color and spotted with tiny pores (NOT gills). False turkey tail mushrooms (Stereum spp.) have a matte, tawny underside with no visible pores.

Here are some online resources to help you with identification:

-

After you’ve successfully identified it, look for healthy, young flushes of mushrooms to harvest. Leave plenty behind, so the mushroom can make spores and reproduce. Our family likes to chew on a piece or two while hiking for a fun fungal gum alternative.

You can also find turkey tail in medicinal mushroom preparations online and in your local health food store.  

Contraindications: Avoid if you have mushroom allergies.

When it comes to fighting infections and warding off looming illnesses, antimicrobial herbs will be among your very best helpers. These remedies contain compounds that directly deter pathogenic bacteria, fungi, viruses, and protozoans.

You’ll find that antimicrobial herbs are valuable remedies for the common cold, the flu, and manageable mild to moderate infections. Depending on the type of infection, antimicrobial herbs are applied topically or taken internally, and in some cases, both applications are beneficial.  I keep a reserve of these herbs in my apothecary throughout the year, but I take special care to stock up in preparation for the arrival of cold and flu season.

It’s typically helpful to combine herbal antimicrobials with herbal immunostimulants, which are used on a short-term basis to boost immunity during the initial stages of an infection, as well as throughout the duration of an infectious illness. Classic immunostimulating herbs include echinacea, garlic, and spilanthes. You can read more about how to use them in our article, Herbs for the Immune System.

It’s important to realize that herbs aren’t always the only support you might need to combat infections. Antibiotics and conventional medical care have their place, especially with young children and serious infections. For a list of warning signs that indicate the need for medical care, please visit the article above.

Note that this article is introductory in scope and doesn’t fully cover each medicinal. If you plan to forage any of these herbs (with the exception of goldenseal and white sage, which are threatened and should not be gathered from the wild) you’ll need to seek out identification tips. You’ll also need to learn foraging ethics and guidance before you harvest any plant from the wild! There are deadly poisonous plants out there, so proper identification is paramount.

See our articles on Foraging and Wildcrafting on the blog for more guidance. This is just the tip of the antimicrobial iceberg—for a longer list of antimicrobials, please visit our Herbs for the Immune System.

Japanese honeysuckle (Lonicera japonica)

1. Japanese Honeysuckle (Lonicera japonica, Caprifoliaceae)

Parts Used: Floral buds, opened flowers, stems, and leaves

Preparations: Tincture, decoction, infusion, honey, syrup, poultice, douche, and compress

Herbal Actions:

  • Antiviral
  • Antibacterial
  • Antifungal
  • Immunostimulant
  • Anticatarrhal (decongestant)
  • Expectorant
  • Antioxidant
  • Diuretic
  • Astringent
  • Alterative
  • Anti-inflammatory

I would venture that many of you are intimately acquainted with the blooms of this familiar vine and have partaken of her nectar, sipped straight from the flower’s slender golden tube. All you sucklers will be happy to know that the familiar honeysuckle vine is also a potent medicinal, with far-reaching applications.

Japanese honeysuckle flowers are powerfully antimicrobial and are one of the most widely used medicinal herbs in the world. Honeysuckle can be used internally as a tea or tincture and externally as a poultice or wash. The floral buds and opened blooms are immune stimulating, and strongly antibacterial and antiviral. I use the flowers internally to address hot, inflamed conditions—head colds, flu, urinary tract infections, laryngitis, mastitis, sinus and ear infections, and lower respiratory infections.

The flowers can be gathered as buds and as opened blooms, and tinctured fresh in alcohol. Honeysuckle is also effective as a tea; I combine it with mint and lemon balm to mask its slight bitterness.

Many species of honeysuckle have been used medicinally throughout North America, Europe, and Asia. However, their traditional use and the part employed (bark, leaves, flowers, etc.) varies among species; the biochemistry of the genus is also variable. For example, some honeysuckles have poisonous berries, and some have leaves and bark that can cause vomiting and diarrhea.

Subsequently, we can’t make broad speculations about the medicinal qualities of the entire genus. We’re only talking about Japanese honeysuckle in this article—don’t extrapolate the information here to all honeysuckle species.

Japanese honeysuckle (Lonicera japonica)

Japanese honeysuckle is native to eastern Asia. It has spread throughout much of the world and can now be found in South America, North America, Oceania, and Europe. In the United States, it is especially prolific in the Southeast, but it can be found in almost every state, including Hawaii. Do not plant Japanese honeysuckle as it’s seriously invasive. Harvesting it for medicine is one way to slow its spread!

Japanese honeysuckle is a perennial woody vine that twines around its host, reaching 30 feet (9 m) in length. It can be found in thickets, pastures, and young, open forests and along fencerows, roadsides, and the forest’s edge. It is not a shrub, unlike many other honeysuckle species.

The leaves are elliptical to oblong and leathery when mature (they feel thickish); they are opposite. The leaves grow to 1.2–3 inches (3-7.5 cm) long and have ciliate margins (tiny hairs, like cilia, growing from the edge of the leaf). The vine has peeling, brown bark.

Here are some resources to help you properly identify Japanese honeysuckle:

-

Contraindications: Some species have been used to stimulate the menses and childbirth, so I would avoid the internal use of honeysuckle in pregnancy to be on the safe side. Make sure to only gather this species; other honeysuckles are not necessarily safe or used medicinally in the same fashion. The berries are poisonous.

Usnea (Usnea spp.)

2. Usnea (Usnea spp., Parmeliaceae)

Parts Used: Whole lichen

Preparations: Tincture

Herbal Actions:

  • Antiviral
  • Antifungal
  • Antibacterial
  • Antiprotozoan
  • Anti-inflammatory
  • Anticatarrhal (decongestant)

Usnea is an important medicinal to have on hand in the medicine cabinet. Winter is a fine time to gather Usnea, as heavy winds during storms often knock down branches covered with this versatile medicinal. Lichens are symbiotic organisms, consisting of a fungi and algae. Usnea is fairly easy to recognize, with its thin string-like branching pattern. It can be differentiated from similar lichens by pulling one of the "strings" slowly apart and looking for a thin white strand at the core.

Usnea is especially helpful in treating respiratory congestion, as it is drying and anti-inflammatory, in addition to being antimicrobial. I primarily use Usnea in tincture form, and combine it with immune stimulants, for upper and lower respiratory infections. It is also one of my treasured remedies for urinary tract infections, along with corn silk (Zea mays), uva-ursi (Arctostaphylos uva-ursi) and marshmallow root (Althaea officinalis). Most urinary tract infections can be successfully addressed with this protocol, along with unsweetened cranberry juice. Be sure to look out for warning signs of a kidney infection, such as fever, back pain, and persistent urinary symptoms. Kidney infections are best addressed with antibiotics.

Usnea (Usnea spp.)

Usnea is more effective as a tincture rather than tea when treating infections, as its antimicrobial properties are more alcohol soluble. I tincture dried usnea with organic grain alcohol at 1:4 95%, and fresh usnea at 1:2 95%. I use a glass blender to create an usnea/alcohol slurry.

Contraindications: Usnea should only be used on a short-term basis, and can be very drying to the sinuses.

Garden sage is a fine anticatarrhal (Salvia officinalis)

3. Garden Sage (Salvia officinalis, Lamiaceae) and White Sage (Salvia apiana, Lamiaceae)

Parts Used: Leaves and stems

Preparations: Tea, tincture, honey, gargle, smoke bundle, and steam inhalation

Herbal Actions:

  • Antibacterial
  • Antifungal
  • Astringent
  • Carminative
  • Anti-inflammatory

Illustrious for its culinary uses, garden sage is also a versatile medicinal herb. In fact, its name heralds from the Latin salvere, “to save”, referring to its famous reputation as a lifesaving remedy. This mint family herb has been used therapeutically for centuries with far-reaching applications, ranging from soothing sore throats to washing wounds.

White sage (Salvia apiana)

White sage’s medicinal uses are very similar to those of its cousin, although the former is more antimicrobial and stimulating than its domestic brethren. I find that a steam inhalation of the leaves helps to break up respiratory congestion in both the lungs and the sinuses. Try combining it with thyme (Thymus vulgaris) and bee balm (Monarda spp.) in the steam pot, along with a few drops of eucalyptus essential oil.

Sage leaves have traditionally been burned after sickness to purify the home. White sage is a sacred herb to many Native American peoples, and its overharvesting by Westerners has resulted in the demise of wild populations.

Because white sage is becoming increasingly rare in its native habitat due to over-gathering, we suggest learning how to cultivate this precious herb. We have a growing guide (plus recipes!) on the blog. Do not gather or purchase wild-harvested white sage.

Contraindications: Sage is a uterine stimulant and should not be used in large doses by pregnant women. In medicinal quantities, it can dry up the breast milk.

Red bee balm (Monarda didyma)

4. Bee Balm (Monarda spp., Lamiaceae)

Parts Used: Leaves and flowers

Preparations: Tea, tincture, honey, and steam inhalation

Herbal Actions: 

  • Antibacterial
  • Antifungal
  • Diaphoretic
  • Anticatarrhal (decongestant)
  • Expectorant
  • Carminative
  • Nervine
  • Antirheumatic
  • Emmenagogue
  • Diuretic

I try not to play favorites—even with plants—but I must confess that this group of herbs is among my most cherished of botanical sweethearts. Bee balm is a powerful antimicrobial cold and flu remedy (helps to clear the sinuses, break a fever, and overcome infection). It can be taken internally as a tea or tincture and used as a steam inhalation to treat sinus congestion. It’s also a gentle sleep aid, helping to bring rest during the discomfort of illness.

There are over twenty species in the Monarda genus, all of which are native to North America. It is important to use scientific names with this group, as common names are many and often used interchangeably. The species might be called wild bergamot, bee balm, Oswego tea, or horsemint, depending on where you live and whom you are talking with. The name wild bergamot is especially confusing, as bergamot is also applied to the essential oil from the similarly scented Citrus bergamia. It is the citrus oil, and not Monarda, that is used to flavor Earl Grey tea.

Wild bergamot (Monarda fistulosa) growing alongside purple cone flower (Echinacea purpurea)

The bergamots are some of the showiest medicinals for the garden, with their tousled tops of crimson and lavender. The flowers are edible, adding a vivid zest to any meal. You can use any of the bee balm species in the Monarda genus medicinally.

Contraindications: Do not use in pregnancy, as bee balm is a traditional menstrual stimulant. As with other spicy herbs, bee balm may aggravate heartburn.

Goldenseal (Hydrastis canadensis)

5. Goldenseal (Hydrastis canadensis, Ranunculaceae)

Parts Used: Rhizomes, roots, leaves, and stems (the rhizomes and roots are most potent)

Preparations: Infusion (leaves), decoction (rhizome and roots), tincture, gargle, and powder

Herbal Actions:

  • Antimicrobial
  • Anti-inflammatory
  • Anticatarrhal (decongestant)
  • Astringent
  • Emmenagogue
  • Alterative
  • Bitter

Goldenseal’s vivid yellow roots are famous in the Native American pharmacopeia and are among the most purchased herbs in commerce today. Unfortunately, goldenseal is often used incorrectly—at the first sign of a cold or flu. At this stage, goldenseal's drying qualities can actually counteract the beneficial “flushing” efforts of the immune system—think thin mucus and a runny nose.

Goldenseal becomes helpful when the symptoms of a cold or flu move deeper into the body or become more serious; for instance, when a sinus infection develops or when pneumonia becomes a concern.

You’ll want to reach for the goldenseal specifically when thick yellow-green mucus or discharge is present. You can use it as a gargle or take it internally as a tea or tincture.

Goldenseal can be used topically in powder form, or as a compress or wash to treat skin infections.

Goldenseal (Hydrastis canadensis)

Please do not gather goldenseal from the wild or purchase wild roots, as they have been heavily overharvested. Grow your own if you can or purchase organically cultivated roots. Take a peek at our Guide to Growing Woodland Medicinals for more information on cultivating goldenseal.

Contraindications: High doses of goldenseal should only be taken for short periods of time (no more than three weeks), as it can cause inflammation and irritation to the mucous membranes and digestive tract. Even in small doses, tonic use can be overly cooling and drying to most constitutions. Other contraindications include high blood pressure, pregnancy (large doses can cause premature contractions), and breastfeeding.

Last winter, I had the pleasure of visiting the Kauai Farmacy Gardens with my family on a visit to Kauai, affectionately known as the Hawaiian “Garden Island.” I was intrigued by their thriving tropical farm-to-apothecary business model and was eager to meet the plants and people involved. Doug Wolkon, one of the co-founders of the gardens, generously spent an afternoon with us, showing us around the plantings and apothecary.

I was delighted to find shoulder-high ashwagandha and tulsi growing right alongside cacao trees laden with pendulous purple pods. Picture clambering passionflower chumming it up with creeping gotu kola. Perky ginger and turmeric leaves growing underneath cinnamon trees. Edible, medicinal, and culinary plants weave together in an exuberant pandemonium that can only be orchestrated by abundant rainfall, warm temperature, and sunshine - a true tropical permaculture paradise!

Dried cacao seeds (Theobroma cacao) are consumed raw as cacao seeds or nibs. Chocolate is typically made from the roasted seeds with a sweetener.

The winding mulched pathways and shady resting spots create an inviting environment for the visitors who come to learn about Hawaii’s medicinal and edible garden flora. During the tour, folks get to interact with the living plants used in the business’ products and then retire to the Tea Lanai to sample tea grown on the land, accompanied by seasonal fruits and nuts.

“Imagine a vibrant garden of paradise lovingly tended to by a small group of nurturing farmers. This is Kauai Farmacy, an organically-farmed oasis located in beautiful Kīlauea on the Garden Island of Kaua’i.”

Founders of Kauai Farmacy, Doug and Genna Wolkon, moved to Kaua’i in 2007, and according to them, “their consciousness began to shift when they started making tea from the leaf of the Noni tree, which is a traditional Polynesian medicinal plant that grows on the Hawaiian islands.”

Three years later, they came into ownership of four acres of fertile pastureland on a river bend in Kilauea and began growing their own medicinal plants. “These herbal gardens slowly and organically grew and transformed into the Kauai Farmacy biodiverse herbal farm; now home to over 60 medicinal herbal plants.”

Permaculture Herb Gardening

This is bioregional herbalism at its finest. Doug and Genna’s operation is entirely organic, based on sustainable methods of cultivation and harvest, and with a direct connection to the medicinal plants used in their products. They focus on plants that are easily grown in their climate and employ permaculture techniques in their plantings.

Medicinal gardens at Kauai Farmacy

Instead of planting vast monocultures of single medicinals, they interplant botanicals in guilds comprised of plants of varying growth habits. Low-growing and spreading medicinals such as gotu kola and spilanthes happily cohabitate with taller herbs such as ashwagandha and tulsi. Grouping unrelated plants reduces insect and disease pressure and more closely mimics what happens in nature.

Herbal Agritourism

Kauai Farmacy is a prime example of a successful farm to apothecary, or farm to ‘farm-acy’, operation. Doug and Genna have taken things one step further by adding a third link to their business chain: ecotourism.

They operate on an innovative Taste/Explore/Learn model. Visitors may taste fresh herbs, spices, and tea blends at their Tea Lanai/Farm Store, explore their diverse medicinal herb gardens guided by their herbal and gardening staff, as well as providing many opportunities to learn more about medicinal plants, and Kauai Farmacy’s harvest and cultivation methods.

Kauai Farmacy creates a plethora of herbal products such as tea blends, tinctures, salves, superfoods, spice blends, hydrosols, and more. They proudly state on their website that “Every plant in every tea is grown on our farm.” One product of interest is their Buzz Chew Edible Herbal Blend, consisting of fresh ground spilanthes, mint, bele spinach, and moringa. This herbal chew is referred to as “nature’s pick-me-up” and is a “mouthful experience you will not soon forget!”

Kauia Farmacy products are made exclusively from herbs grown on the land

For those of you interested in eco-traveling through the Hawaiian islands, or for those who may have interest in starting a Farm to Apothecary Ecotourism business model themselves, we’d highly suggest visiting Kauai Farmacy and their lovely garden oasis. Visit their website to buy products or book a tour!
