The Top 30
A couple of common misconceptions might prove obstacles to the homesteader’s decision to grow her own medicines in her backyard. Is herbal medicine just superstition, “mere folklore,” of no proven efficacy? If that’s true, it is a surprise to big pharmaceutical companies, scrambling to isolate and test the active components of many traditional medicinal plants. A number of powerful pharmaceuticals, for example, have been derived from wild yam. Willow and meadowsweet contain salicylic acid, with analgesic effects like aspirin (but with fewer side effects). Controlled experiments with valerian have supported its traditional use as a sedative to relieve spasms and induce sleep.
The other obstacle to home use of medicinal herbs is just the reverse—the assumption that herbal lore is so arcane that we inexpert homesteaders cannot hope to master its complex, obscure lore without years of detailed study. Let’s take a look, therefore, at the list of medicinal herbs that the California School of Herbal Studies chose as “…a central core of tonic and therapeutic plants…thirty favored plants that we felt could be relied upon to supply an herbalist with pretty much any and all the herbal actions and uplifting virtues required to provide good health care in a home and community.”
- Blackberry (Rubus villosus)
- Black Cohosh (Cimifuga racemosa)
- Calendula (Calendula officinalis)
- Cayenne (Capsicum annuum)
- Chamomile, German (Matricaria recutita)
- Cleavers (Galium aperine)
- Comfrey (Symphytum officinale)
- Crampbark (Viburnum opulus)
- Dandelion (Taraxacum officinale)
- Echinacea (Echinacea purpurea)
- Elder (Sambucus nigra)
- Fennel (Foeniculum vulgare)
- Ginger (Zingiber offininale)
- Goldenseal (Hydrastis canadensis)
- Gumweed (Grindelia spp.)
- Hawthorn (Crataegus oxyacanthus)
- Marshmallow (Althaea officinalis)
- Mugwort (Artemisia vulgaris)
- Mullein (Verbascum spp.)
- Nettle (Urtica spp.)
- Peppermint (Mentha piperita)
- Pipsissewa (Chimaphilla umbellata)
- Plantain (Plantago lanceolata or P. major)
- St. John’s Wort (Hypericum perforatum)
- Skullcap (Scutellaria spp.)
- Valerian (Valeriana officinalis)
- Vitex (Vitex agnus-castus)
- Willow (Salix alba)
- Yarrow (Achillea millefolium)
- Yellow Dock (Rumex crispus)
James Green, in The Herbal Medicine-Maker’s Handbook, adds an additional “five plants and a fungus” to the Top-30 list:
- Burdock (Arctium lappa)
- Ginkgo (Ginkgo biloba)
- Oat (wild: Avena fatua, cultivated: Avena sativa)
- Saw Palmetto (Serenoa serrulata)
- Siberian Ginseng (Eleuthrococcus senticosus)
- Reishi (Ganoderma lucidum)
Simply reading these lists does much to dispel the notion that growing and using home medicines need be mysterious or arcane.
“Hey, this looks easy!” Many of these plants are well known to us, and may already be growing in our landscape or garden. Blackberry, calendula, chamomile, comfrey, mullein, willow—who knew that these ubiquitous and unobtrusive members of our local plant communities would be in a “top thirty” list of medicinal herbs? With medicinal plants so familiar already surrounding us, the idea of home plant medicines starts to feel a lot more comfortable.
“Some of these are weeds, for heaven’s sake!” We’ve been conditioned to think of dandelion, plantain, stinging nettle, and yellow dock as “the enemy” to our gardening, or to landscape beautification. Perhaps it’s time for us to revise our conception of “weeds.” The insistence of a plant on being a part of our local ecology suggests that we explore its role and contribution, rather than devise strategies to eradicate it. Any plant that offers to boost our health should be welcomed and honored, not denigrated as a “weed.”
“Hey, I grow that for food.” It is too bad that in our time “medicine” has come to be understood as a powerful, out of the ordinary (and probably vile tasting) substance taken in a heroic intervention to cure illness and restore health. An alternative view has been available, however, at least as far back as 400 B.C., when Hippocrates said, “Let your food be your medicine, and your medicine be your food.”
Growing and Using Medicinal Herbs
Readers of this site know that a major emphasis of mine is the integration of components in the homestead, with one project serving several needs. Growing medicinal herbs fits right in with that strategy.
Medicinal Herbs as Foods
As already said, many of the plants we’ve come to rely on for food also offer medicinal actions. In some cases, the medicinal part is different from the food part—for example, it is the root bark of blackberry which is used medicinally. But in many cases, it is the edible part of the plant itself which is a kind of “superfood,” toning and balancing the body while adding “punctuation” to our meals—cayenne (a general, circulatory, and digestive system tonic), fennel, ginger, and peppermint. We should incorporate such herbs more frequently into the daily diet, and explore their use in a more directed way when there is a special need. We might make an infusion of fennel, for example, to treat colic, or to stimulate digestion or appetite.
Some “weeds” such as dandelion and stinging nettle are highly nutritious and convey numerous health-promoting effects. Burdock root is considered an important detoxifying herb, and is easily added in small amounts to soups and stir-fries.
Remember too that herbs can be used to make other foods with medicinal effects. In previous eras, a wide range of medicinal herbs—yarrow, ginger, wintergreen, licorice, St. John’s wort, elder flowers and berries—were used to flavor (and preserve) beers and ales. Mead, a fermented beverage made from honey, has medicinal effects in its own right, but can also be made with herbs such as heather that boost its medicinal properties. Vinegars and vegetable oils can be infused with herbs such as rosemary, garlic, and cayenne, and used on salads and other dishes to promote health.
Boosting Insect Diversity
Wise homesteaders know that the solution to damaging insects is not a program for killing insects, but encouraging even more insect diversity, especially by cultivating plants that flower throughout the growing season. Many common medicinal herbs–such as calendula, chamomile, echinacea, fennel, peppermint, and yarrow–are flowering plants, and offer the valuable “fringe benefit” of providing food and shelter for beneficials as well. Plantings of flowering herbs are more effective at encouraging our insect buddies if incorporated throughout the crops to be protected, rather than planted in their own little fiefdoms.
Herbs as Fertility Plants
Smart homesteaders also know it is possible to grow more of our own soil fertility. Isn’t it fortunate that some of the best fertility plants have medicinal properties as well? Comfrey (used for healing wounds and broken bones) and nettle are high in protein (nitrogen), and can be used as nutritive mulches or to “spark” a compost heap. Dandelion and yellow dock are deep-rooted “dynamic accumulators” which “mine” minerals from the subsoil and make them available to more shallow-rooted crops.
Herbs as Fodder Crops
Many medicinal plants do double duty to provide fresh green (or dried) fodder for our livestock. I find that dandelion and yellow dock stay green deeper into winter’s chill than any other forage plant—I dig them up and feed them to my winter poultry flock by the bucketful. Oats is an excellent nerve tonic, and can be used to feed livestock as well, either cut and fed green, or self-harvested by the animals themselves. My geese love comfrey.
Other Ecological or Landscape Uses
Hawthorn and willow might be planted for shade, as a windbreak, or as a “living fence.” As such they offer important ecological benefits (bird and wildlife shelter, moderating the effects of wind and heat and loss of soil moisture to evaporation) in addition to their medicinal uses.
And Don’t Forget Mushrooms
There is growing recognition of mushrooms as important medicinals—reishi and turkey tail, for example. Some edible species such as shiitake and maitake are also being studied for their medicinal properties. In addition, mushrooms serve as decomposers—for example, speeding the decomposition of stumps and slash from woodlot thinning operations and their conversion to soil humus.
Growing Medicinal Herbs
Where should you grow your medicinal herbs? Everywhere you possibly can. There are traditional medicinal plants to fit any micro-ecology in the homestead. For example, the drier, more exposed parts of the homestead can be planted with chaste berry, lovage, milk thistle, rosemary, rue, clary sage, hyssop, lavender, lemon balm, and thyme. Wetter areas might host mullein, peppermint, self-heal, angelica, cardinal flower, goldenrod, and skullcap.
I have planted a woodland garden of medicinal and culinary herbs in a fold of our small woodlot which is more likely to stay moist than any other location on our property. Shade-loving herbs growing there include goldenseal (an important anti-microbial for acute infections, a key medicinal plant of many Native American tribes), bloodroot, downy rattlesnake plantain, Solomon’s seal, wild ginger, spikenard, wild yam, black cohosh, and blue cohosh.
You may have been told that herbs “like to grow in poor soil.” While it is true that most herbs do not have the high nitrogen requirements of heavy feeders like corn and squash, every plant prefers to grow in soil that is loved and nurtured. Just as in the garden, do everything you can to increase the organic matter in your soil (adding composts, using mulches, growing cover crops), and your medicinal plantings will respond accordingly.
Did you notice in the list above the plants marked with an asterisk? Those are plants which United Plant Savers has designated as “at-risk” for extinction from over-harvesting. Responsible herbalists avoid “wild-crafting” of endangered herbal species—and indeed, help preserve these precious parts of our ecological heritage by growing and propagating herbs like goldenseal, pipsissewa, black cohosh, American ginseng, and bloodroot.
Making and Using Plant Medicines
Let your kitchen be your pharmacy. With a reliable beginner’s guide to home medicine, you will require no equipment other than the pans, measuring utensils, electric coffee grinder, strainers, funnels, mixing bowls, etc.\ probably already resident in your kitchen. If you get excited about the process, you can always add equipment such as presses and distilling equipment for making more sophisticated extractions.
You will be amazed that you can duplicate in your kitchen all the forms in which you have encountered “medicines” in the past: tinctures (based on alcohol, glycerin, vinegar, even wine), infusions (herbal medicines can be as simple as a cup of tea) and decoctions, lozenges, capsules, syrups, salves, and lotions—as well as some that are new to you (but would not have been to your grandmother) such as poultices, fomentations, and herbed water baths.
Be aware that traditional herbal practice almost always features using the whole plant, or extracts therefrom, as medicine. Modern pharmaceutical preference for isolating a single component of a plant as the “active ingredient,” and administering that element in isolation from its hundreds of other compounds—results in the greater incidence of unintended side effects of modern medicines, to say nothing of their vastly increased cost. Not only do the complementary compounds of the whole plant help balance its actions and alleviate possible side effects, there is also evidence that some may help “feed” our vital intestinal flora, and thus act as a beneficial (and free) probiotic in the digestive tract.
The fact that herbal medicines are “natural” does not mean they can be used carelessly, without regard to possible hazards. Some of our potential plant allies are quite powerful indeed, and can be dangerous if misused. Some can be confused with dangerous look-alikes as well, if we are not careful. Here are some essential but common-sense rules for safe medicinal use of plants.
- Know the plant
- Proper plant identification is crucial—there is no room for carelessness or guessing games. Fennel is on our “top thirty” list, and closely related species such as parsley, celery, dill, cilantro, and lovage have a long history of medicinal use as well. Two members of this family are deadly poisonous, however—water hemlock and poison hemlock (the plant used to execute Socrates)—and mistakes with these look-alikes can be fatal. This sounds scary, but we need simply to practice the same common sense we use when instructing our children about any hazardous plant in their environment—poison ivy, Jimson weed, lily-of-the-valley.
- Know the part to be used
- It may be that one part of a traditional medicinal plant is safe to use, while others are off limits. For example, elderberry flowers and berries are safe for the beginner to use (to make medicines for flu and fever), but the bark can have toxic effects.
- Know the application
- Some plants that can be seriously toxic if taken internally, can be safely used externally. An excellent example is foxglove (Digitalis), which can be fatal if ingested, but can be used to make a “fomentation” to promote wound healing.
- Know the dosage
- It should never be assumed that “if a little is good, a little more is even better.” Indeed, James Green observes that small doses of German chamomile can provide positive effects for the nervous system that larger doses cannot duplicate. In some cases, the possibility of side effects or toxicity goes up with increasing dosage. Remember that dosage is keyed to body weight as well, so special care must be taken when administering herbal medicines to children.
- Though unwelcome side effects are much less common in herbal medicine than in pharmaceuticals, it is wise to “read and heed” herbal literature to minimize possible side effects. For example, herbals high in tannins—such as yellow dock (a liver stimulant and laxative)—can be a problem for individuals with a history of kidney stones.
- Remember individual sensitivities
- An individual might have an allergic reaction to a traditional medicinal plant safely used by others. When beginning use of a medicinal herb—just as when trying a new food—start with a reduced amount and work up to a normal dose.
- Be aware of restrictions on use
- Some herbs safe to use by the general patient may not be appropriate for children or the elderly. Most importantly, pregnant women should always be considered a special case. With regard to any plant medicine, the responsible herbalist will consider the issue of safe use during pregnancy, and will err on the side of caution. Some herbs such as black cohosh, comfrey, goldenseal, mugwort, and yarrow should be avoided entirely by pregnant women. Others such as cayenne and ginger might be used, but very sparingly.
- Recognize the limits of your own expertise
- There are many herbs that are easy and safe for the beginner to use—a good place to start is with herbs commonly used as food and in teas. Others require far greater experience, knowledge, and skill. In the case of elderberry bark, mentioned above, it actually is used medicinally, even for internal applications. However, it is strong medicine indeed, and should be used only by those who know what they are doing. The rest of us should stick with the more user-friendly plants and applications, and seek out a reliable teacher if we want to advance.
The Best Plant Medicine
You may discover as you honor and get to know medicinal herbs, wild and cultivated, that your relationship with these plants grows ever more intimate, more personal. Herbal medicine is not just about using plants as little chemical retorts to synthesize compounds we match one-for-one with symptoms of illness. While the chemicals plants create can indeed be healing, our growing alliances with plants are even more so.
You may find in your walks through wood and meadow that a certain plant “steps out” of the background and presents itself to you in a personal way. Or you may experience as you plant a particular herb a sense of recognition, of kinship. Pay attention to such moments and to such plants—they are offers of alliance, opportunities to heal the rift that has opened between us and the living world. This is the best medicine of all.
