An East African Materia Medica

Serengeti



Introductory notes: the plants referenced here are ones I have been using in the highlands of north-central Tanzania, at an elevation between 7,500 and 8,500 feet from sea level. The climate is generally moderate, with mornings in the 50s and daytime highs in the 80s. It is the rainy season right now - the flora will be different in the drier months (May to October). Generally, one could find these species in a broad area from lake Victoria in the west, north past Nairobi in Kenya, out to the Ethiopian highlands in the east and down past the Ngorongoro crater in the south.
I reference plants that I have been able to positively identify, gather, prepare and apply myself. Preparation notes are included. Botanical names, as well as Swahili (Swa.) and Maasai (Maa.) names are included if known. Clinical outcomes and observations are from my herbal practice in the context of Wasso District Hospital over the course of about four weeks of work. Patient volume varies; on a typical day there will be five or six patients returning for acute wound care, two or three new acute wounds of varying severity, two or three chronic wounds or infections, and between two and six cases from the internal medicine wards (chronic asthma, diabetes, hypertension, peptic ulcer, HIV and its complications).
Patient diets are generally similar, and quite simple: rice and cornmeal are the chief carbohydrates, and beans the chief source of protein. There are some tomatoes, cabbage greens and carrots used, and occasional meat (goat, beef). Sources of fat (used in abundance) are questionable, consisting mostly of refined vegetable oils. In the context of the hospital, dairy products are virtually absent. One conspicuous factor is the ubiquitous use of soda (often up to six or more bottles a day) which is in large part at the root of the cases of diabetes and gastrointestinal ulcer - the latter also connetected to the near-universal Heliobacter pylori infection and the frequent, indiscriminate use of antibiotics.
This inappropriate use of over-the-counter (black market) antibiotics, as well as prescribed antibiotics in the hospital setting, have led to both gastrointestinal disturbance and antibiotic resistance, particularly in cases of cutaneous staphylococcus infection (but also typhoid and pneumococcus). This makes the use of herbal medicine all the more valuable and important. Wound management in acute cases usually involves simply a liquid iodine solution, though in chronic wounds I used herbal treatment exclusively. Aside from that, unless otherwise noted in discussing specific cases, treatment used was entirely herbal.




Achillea millefolium (Yarrow): truly a wound plant like no other. Luckily, there is a fair supply planted as an ornamental in the hospital garden. Daily preparation involves gathering a large handful of leaves and a flowerhead or two, coarsely chopping, placing them in a bowl and using just enough hot water to cover the herb. Then the mixture is blended and the juice strained and pressed. Yarrow juice is used as a wound wash for chronic ulcerations in cases of leprosy, diabetic foot ulcer, or unaddressed infected wounds. Apply liberally to gauze and use to scrub and irrigate the wound, cutting away necrotic tissue as necessary, twice daily. Saturate and pack gauze into deeper wounds if prurulent discharge is present (wet-to-dry dressing, iodine alternative, very effective).


Zanthoxylum chalybeum (Maa: loisugi): a bitter, pungent preparation is made by collecting the bark (outer and inner, after removing knobs and thorns), cutting into coarse strips, and decocting about one cupful of shredded bark to 1/2 gallon of water for 15-20 minutes. The decoction is yellowish-brown and can be used to irrigate wounds (mixed with yarrow juice) and internally for peptic ulcer and as a bitter digestive tonic, dosed at about 2 ounces of decoction twice a day before meals. One patient (who began his treatment with two days of goldenseal [Hydrastis] powder, 1/4 tsp. twice daily before food but then switched to this decoction) remarked that his after-meal symptoms of burning pain were completely resolved. He had previously tried a range of antibiotic treatments with no success.


Bidens pilosa: I tried this weedy plant as an alternative to yarrow for washing wounds, with limited success. It seems to lack some of the topical astringent hemostatic effect of yarrow. However, it is quite useful taken as a juice for internal use, particularly in cases where vitality is weak, there is anemia and/or fatigue, or the tissue (internal or external) seems in need of drying or toning. When these constitutional signs accompany infection, Bidens provides valuable systemic anti-infective support. This was particularly evident in a case of leprosy, where yarrow and usnea powder helped the lesions considerably, but failed to completely resolve the issue until Bidens was added. The aerial parts are harvested daily from specimens that have just started flowering (no seedheads), the leaves garbled from the stems, placed in a bowl and barely covered with cold boiled water. Then the mixture is blended and the juice strained and pressed. Patients take around two ounces of juice three times a day. The juice will keep at room temperature for 48 hours, but any leftovers should be discarded after that.


Usnea spp. (barbata / longissima): this hardy and cosmopolitan lichen can be identified by the white inner fungal cord (medulla) and the green outer algal cortex which can be "stripped" from the medulla as one might do with electrical wire. It grows at higher elevations, hanging off old tree branches closer to the hilltops, blowing in the near-constant wind. Here you can find it by the bagful. I have been using it primarily as a wound powder, particularly in long-standing damp lesions where I leave it embedded in the tissue for two days at a time before cleaning it out with yarrow/loisugi mixtures. It helps to form a nice matrix for granualtion tissue, while preventing infection and drying suppuration very effectively. In the leprosy case, it actually embedded itself into new skin, forming a sort of hybrid usnea-callous that closed the wound while also providing excellent protection from the pressure and friction that caused the lesions to re-open (Mycobacterium leprae can infect peripheral nerves leading to loss of sensation, certainly the case in my patient). My preparation method involved sun-drying the lichen until it was brittle (thereby increasing usnic acid content, too), then just cutting it for 15-20 minutes with a serrated blade until it became a mass of green powder and tangly white strands. The mass gets passed through a mesh strainer to leave only a fine, green powder which is liberally applied to wounds.
A note regarding leprosy: dressing the wounds is often counterproductive. They are moist and ooze quite a bit, and enclosing the discharge actually retards healing. Twice daily application of usnea powder to replace any that fell off during walking does the trick after a week to ten days, along with Bidens internally and good foot hygiene. Patient was discharged with a big wad of lichen to use and apply as a spit poultice (small amount at a time) should any further wounds develop. He had been in the hospital for six weeks before we began herbal treatment. Antibiotics had been used (internally and topically), along with bleach soaks, to little effect.


Argemone mexicana (Maa: langanum): a britsly Papaveracea with a bright orange latex and beautiful flower, it usually grows as a weed in planted fields. It is used by the Maasai as an immediate antiseptic and hemostatic treatment for minor cuts and wounds - really useful on trail walks. The latex, which flows profusely when any part of the plant is broken, tastes remarkably like celandine's. I regret not having had the opportunity to try it in cases of cholecystitis, though there was one patient who did come through minor theater with that condition. It was a very instructive abdominal exam, with all the classic signs in the right upper quadrant and referred scapula pain too. Ultrasound was inconclusive in her case. She was sent home and told to avoid fats before we got a chance to start herbal treatment.


Zingiber officinale (Swa: ntangawezi): this famous rhizome needs no picture nor description. It is readily available, still covered in red soil, at the weekly market in town. I purchased a big pile of it for the equivalent of about $2. While I made the occasional anti-nausea tea (for Westerners), the main use of this plant was as an anti-inflammatory circulatory stimulant to support the healing of chronic diabetic foot ulcers. I had two patients whom I followed with this treatment, along with caring for their primary wound and conducting daily foot and leg massages to promote lymphatic drainage. The procedure for preparation was simple: grate the fresh rhizome (about 1 TBS), add about 1 cup boiling water, let steep five minutes or so, then saturate a clean cloth with the infusion and apply hot to the foot. Before applying, I would take the leftover grated rhizome and apply it to the dorsum of the foot, then wrap it up. This happened twice daily.
A note regarding diabetic foot ulcers: one patient developed the ulcer after stepping on an acacia thorn which pierced her flip-flop and went straight through her foot, emerging from the top a bit lateral and proximal to her big toe. The resultant abscess had to be surgically opened, and a chronic wound developed. It was about the size of a nickel when I first saw it, and the whole foot was noticeably edematous. She could not walk on it. Daily bleach soaks and antibiotics had not really helped for the five weeks she'd been doing them. Within three days of using ginger and eliminating the bleach, the swelling began to subside and peripheral pulses returned. After about a week, the foot was almost normal in size, and the ulceration had reduced dramatically in diameter and depth (yarrow juice + usnea powder). Her course of antibiotics had ended a few days before. After two weeks she was walking pain-free, the ulceration was gone and fresh pink skin remained, and she was discharged with a big bag of prickly pear cactus pads.


Opuntia ficus-indica (prickly pear, Swa: freisha): an exotic cactus, the prickly pear has naturalized extensively across the Tanzanian highlands. Some specimens I've seen are over ten feet tall, bristling all over with long spines and tiny, fiberglass-like hairs that are perhaps even more of a hazard than the visible thorns. The fruits are starting to ripen here right about now, and can be used medicinally, but I harvested the wide pads by scraping them clean of spines with my knife's edge, then cutting the pads. Some clinical research looks at the fire-roasted pads (used as a food source in the American southwest), but I just went ahead and juiced them fresh. A little water is added to the chopped, cleaned pads (scraped, washed, and towel-dried), then they are blended and the juice is taken, at doses of about 1/2 cup full, twice daily before meals. I used this juice, sometimes spiced with a teaspoon of cinnamon powder if available, for managing elevated blood sugar associated with diabetes.
A note on diabetes: this is a relatively new disease here. None of the Maasai I worked with knew of any diabetics in their community. The cases were in overweight, non-Maasai community members, and staff members at the hospital. Once again, it seems to be a disease of relative affluence connected perhaps to that wonderful American export, the sugary soda, which is shared at almost every social gathering and can be a bit of a branded status symbol. Blood glucose levels are measured here as they are in Europe: in millimoles per liter, unlike in the US where the units are milligrams per deciliter. The conversion is based on the molecular weight of glucose (one mole of C6H12O6 is 180 grams), so 10mmol/L = 180mg/dL. That's a pretty high fasting level! The guideline is 6mmol/L, or about 104mg/dL, for a fasting blood glucose. One staff member at Wasso Hospital went from 10.4mmol/L to 7.8mmol/L in less then a week using Opuntia and cinnamon (and strictly avoiding soda). This result was a bit amazing to me, but isn't out of the realm of possibility (she was certainly pleased). Some confounding factors: I'm uncertain whether she had drunk any soda before her first test (would definitely have skewed the result, but even after a soda your BG shouldn't be 180); two different lab techs conducted the two tests (you might say lab work is objective, but I'm not so sure). Regardless, her BG levels have been a lot better in the mornings with the Opuntia juice than suggested by past test(s).


Aloe spp. (vera, alata, ferox. Swa: msubili): This succulent, rich in soothing gel, is a classic burn remedy. To be honest, I used it mostly for our family and other Westerners transiting through the guest house - but was also able to apply it on the more superficial burns I saw in minor theater. It is excellent to relieve pain and speed healing for superficial burns, but I'm not confident enough in its antiseptic power to recommend it on full-thickness burns after the top charred layer of skin sloghs off. However, with extensive burns, one of the major risks after infection is dehydration - and aloe can help a lot for that. One child who had been sweeping the floor of her home was extensively, though not deeply, burned when her wrap caught fire. Both arms and the back and front of her torso suffered partial thickness burns, and the evaporative fluid loss was high. The healthy skin on her legs showed pretty substantial dehydration, despite a lot of drinking. We used aloe five or more times a day (training her parents on how to apply it), and silver cream just twice over a week, and there was no infection and much less dehydration.
Preparing aloe is fairly easy. You cut whole leaves, then remove the spines on the sides of the leaves (taking care not to cut too deeply and expose the demulcent pulp). Then, simply cut cross-sections of leaf, peel off the green parts, and mush up the gel in a container. Apply liberally to the affected areas. One note: the stuff is remarkably bitter. Wash your hands after preparing.


Phytolacca dodecandra (Maa: ol'diangorras): I was excited to find the orange-red berries of this local species of pokeroot. It grows vigorously, more vine-like than its American cousin, and has a thick and juicy root. With some coaxing, I was able to harvest a fairly sizeable chunk. From this I cut wide slices, which were then pounded and the juice strained out. I used about 1/2ml of this juice on myself at first, then closer to 1ml twice daily for an HIV patient who had lymphatic swelling in cervical, axillary and inguinal nodes. She saw some improvement from this approach - not a dramatic reduction in swelling, but a marked reduction in tenderness. I searched extensively for cleavers (Galium), but was unable to find this species outside of the Ngorongoro crater rim. Needing a lymphatic, I opted to try this Phytolacca and was not displeased with the results. The flowers smell amazing, kind of like lilacs. The Maasai (at least those I spoke with) only know it as a poison plant and warned me against eating the berries.


Eucalyptus globulus (Swa: Makaratusi): These trees were planted by colonists, and now there are some huge specimens, usually along main roads but often in the more secluded (and less fumigated) corners of the villages, by streams. Many trees have been cut down, especially those next to cultivated fields, as they tend to suck up all available water and can contribute to crop loss during drought. Nevertheless, the leaves are abundant and quite fragrant, and I would place whole branches, slightly broken up, in pots of steaming water for patients in the pediatric ward who had chest congestion. The steam smelled nice, nobody complained, and some of the patients remarked that they were breathing more easily after taking big inhalations of the steam. This was especially evident in a case of chronic asthma, aggravated by the dusty conditions here, where eucalyptus steam inhalation provided almost immediate relief. Use a towel over your head for maximum steam concentration.


Olea africana (Maa: ol'orien): These strange looking olive trees live quite a long time, and have thick, gnarly trunks that end in a burst of spindly branches, loaded with leaves and olive-like fruits with little seeds that mature to an unpalatable orangeish color. I harvested the leaves to use as a treatment for hypertension. This condition is relatively rare (most blood pressures were in the 100/60 range) but more and more folks are experiencing higher blood pressures and atherosclerosis these days - even in the Maasai community. I'm not sure exactly why this is. Nevertheless, I'd give out bagfuls of fresh olive leaves, with the instructions to chop or pound a good handful and steep in a pint of hot water, drinking daily in two divided doses. Results took time - at least a couple of weeks - but I was able to see a small but consistent drop (5-10pts systolic) in blood pressures for those taking these leaf teas consistently.
The Maasai used the leaves for malaria and fever. Given their anti-inflammatory and potentially antiviral effects (extrapolating from research on the European cousin of this tree), these traditional uses make sense.


Commiphora africana (Swa: mturituri): I was introduced to this species as a remedy for colds: the resin that exudes from the bark of older trees is traditionally steamed and inhaled. Also, the root of younger trees is wonderfully fragrant and actually sweet - a remarkable surprise. But seeing as how I couldn't find enough resin, and eucalyptus was working well for chest congestion, I recommended the bark of this plant be chewed as a remedy for high cholesterol and atherosclerosis. I am extrapolating here from research on its cousins C. mol-mol (guggul) and C. myrrha (myrrh), and it is too soon to tell what kind of effect it may have had, but between that and the daily 3-4 cloves of garlic I am optimistic. One gentleman accosted me for a consultation on cholesterol and atherosclerosis while I was buying bar soap to do my laundry at the little shop across the street. He needed some exercise too - I suggested some brisk walking and less hanging out at the shop drinking soda.


Urtica massaica: Oddly, the Maasai didn't have a name for this ferocious species of nettle, preferring instead to give it a wide berth on the trail. The stinging hairs on this plant are stiff and potent even after drying, and can be two to three inches long on the stem. The plants grow to over six feet in height, out in the full sun. The sting persists for 24-48 hours, depending on how deep you're stung, and caused an immediate urticaria rash on my skin (U. dioica just doesn't do that for me). So I started using scissors to harvest the green tops, pre-flowering, and would juice them to a dark-green-black frothy fluid. Delicious. I'd combine it with the juiced berries of Cyphostemma (see below) to make a nutritive tonic for anemic patients. One cupful a day seemed like a good dose. Good nutrition, especially for moms and kids, is really important here: many are anemic, blood is difficult to obtain, and malnutrition is rampant.
Another use of this juice was for symptoms of allergy and upper respiratory congestion in Westerners unaccustomed to the dust and allergens of this environment. Half a cup of fresh nettle juice, once or twice a day, reduced eye itching and nasal congestion. Overall, it is a very nutritious, very drying herb.

Cyphostemma serpens (Swa: mwengele, Maa: ol'kilenyei): this viney, trailing plant drapes itself over low acacias and on termite hills. It produces clusters of berries, which the Maasai harvest while still green to use as a food and especially as a tonic for children. The tuberous root can also be boiled and eaten, though I didn't try this. The fruits have an agreeable sour green flavor, and I expect they contain a fair amount of organic acids and perhaps even ascorbates - a great supplement indeed! So I'd harvest clusters of the berries and juice them up, often with nettles, to add into the diets of those needing a special boost. 1/4 cup of the blend for kids, 1/2 cup or more for adults, once or twice a day.
Traditionally, the Maasai add the fruit pulp to milk and feed it to kids to help them grow stronger.


The bitters: I used the bark of Acacia species for this purpose, primarily for myself, my family, and the Westerners with digestive complaints. I preferred loisugi for local folk, as it seems to be more of a tissue tonic for long-standing gastrointestinal inflammation. The acacias are bitter and, depending how they are processed, possess a varying amount of tannins which can be useful if there are digestive complaints accompanied by loose stools or diarrhea.

Acacia nilotica (Maa: ol'kiloriti): this is an excellent and useful tree though, like most Acacia species, it is viciously thorny. It has a characteristic shaggy, dark brown bark and rounded, yellow pom-poms for flowers. The Maasai go at the trunk with a machete, gathering the middle, soft, tannin-free bark layer. The outer bark is very astringent, and serves as an anti-diarrheal. The innermost layer is very bitter, and acts as a purgative. But the soft middle stuff - just right. At special dates two or three times a year, they boil handfuls of it in a goat stew which is eaten to "cleanse and renew the belly". It is moderately bitter, somewhat reminiscent of yellowdock root in flavor, and small sips (1-2 oz) of the decoction before meals improve appetite and regulate bowel function well.
I myself became quite fond of using the younger branches of this tree, adopting another common Maasai habit. Stripped of thorns, they make excellent toothbrushes and lack the inner purgative bark layer. So, after the morning run and before breakfast, I'd walk around chewing on a six-inch chunk of twig, swallowing the bitter and slightly astringent juice, and rubbing my teeth and gums with the juicy fibrous end.


Acacia drepanolobium (Maa: ol'munishui): nicknamed "whistling thorn" because of the big, dark, hollow galls that catch wind with a characteristic whistle, the Maasai use its roots as parturients to help expel the afterbirth. This is actually a big issue in the local community, with many women suffering prolonged post-partum hemorrhages that can be life-threatening. But I didn't use this tree for that. The inner bark makes another excellent digestive bitter, but it is a bit more pungent and almost numbing to chew, reminding me slightly of kava. Another traditional use is for sore throats, which makes sense (though no throats were sore at Wasso). I used an infusion of the inner bark, about 1 TBS per cup of hot water, with a little honey as a pleasant evening after-dinner digestif. Supposedly these trees, which can grow to 15 feet, are the giraffe's favorite food. I witnessed them browsing on some one afternoon. They have some tricky lips, getting around those thorns.
Walking through the bush, you move from green grass, yellow-barked acacias, red soil and a winding stream into denser forest with loisugi, vines, and epiphytes. Then you pass under a nilotica branch and find yourself on rich, black soil in a sparse forest of whistling thorns. There is a hiss in the air. The trees have a conical growth pattern and a grayish, mottled bark. This, along with the dark galls that look like black spruce cones, makes you feel like you just stepped into a grove of old spruce, towards the top of a mountain on the East Coast of the US. For a moment, the thorns look like needles. Then you see two Maasai kids, long sticks in hand, pushing goats through the thicket - and you're back under the hot sun.


Leonotis mollissima (Maa: ol'bibi): I first grew this plant back in Vermont, where I knew it as "wild dagga". I've smoked the leaves, and it is a mild euphoriant (very short acting). Here, it is an ever-present weed. If the bark of the whistiling acacia is a bitter with mild carminative action, leonotis is first and foremost a digestive antispasmodic, and a decent digestive bitter after that. It is a Lamiacea after all. I recommended the fresh leaves, two or three at a time, for intestinal cramps and spasms where it provides fairly rapid and welcome relief. It is similar to horehoud (Marrubium) in flavor and texture, and shares with it the presence of the bitter lactone marrubiin.


The aromatics: there are numerous scented plants everywhere. Most don't have specific uses, though the locals will rub them on their bodies as perfume, both to increase attractiveness and to repel biting insects. One aromatic plant, Hosnum suave, is eaten by hunters to improve focus during early morning hunts and also to disguise their body odor as the aromatic oils exude through their pores ("that's all the animal will smell", I was told). But there are a few that are, like most aromatics, used as diaphoretics, carminatives, and nervines - as pleasant beverage teas.

Ocimum kilimandsharicum (Swa: kirumbasi): spicy and rich in eugenol and camphor, this plant reminds me a lot of O. sanctum (tulsi, holy basil). It doesn't have quite as intense of a bite. Traditionally, it is used for fevers and upper respiratory infections where I have no doubt it functions as a mucolytic, diaphoretic, and antiviral (it is also rich in rosmarinic acid). I mostly recommended it as a tea, refreshing and carminative after meals, and also as a morning beverage for those who didn't want chai or coffee. It's stimulating and enlivening.


Lippia kituiensis (Maa: ol'sinoni): an indigenous species used by the Maasai for its carminative and diaphoretic effects, it is also called simply "wild tea", because its leaves make a delightful, airy, somewhat citrusy infusion that is excellent in the early evening after a day's work. I consider it a gentle local nervine, similar to lemon balm in its effects though less dry. There is ongoing research looking at its potential antimalarial activity.


There are many other interesting plants. Solanaceae: I harvested and dried Datura stramonium leaves, but was unable to convince an asthma patient that steeping them in Konyagi (some kind of distilled Tanzanian spirit that may start with fermented ginger root) was actually going to yield anything medicinal. Withania somnifera grows wild (I did point its root out to a gentleman who was interested in greater sexual vigor, translating the Ayurvedic name "ashwagandha" as best I could). Solanum incanum, the "Sodom's apple", is everywhere and used for everything from scrubbing pots (its gritty leaves) to dressing wounds (the fresh fruit juice), though I never felt drawn to using it. Lamiaceae: wild patchouli was an awesome discovery. Rosaceae: so many different kinds of wild hybiscus, red flowering, yellow flowering, delicate white flowering. Asteraceae: the important Artemisia annua and some of its cousins grow wild, a treasure against malaria. Very few if any plants are truly dangerous, if you're careful about where you step and avoid the thorns. Euphorbia candelabra, which drips a caustic white latex, may be an exception: it blisters the skin and causes temporary blindness.

In the end, I can only repeat what I've said before: plants are communion. If you get to know them, if you allow them to become a part of you by eating them, drinking their infusions, merging their tissue with yours like usnea in a wound, you become part of the land you're in. If you want to know a place, walk outside. Hold people's hands. Eat what grows. You'll never be the same.

So I leave you with one last plant.
Commelina benghalensis (Maa: engaiteteyai): this is a simple and common spiderwort, and grows in shady places. I'd find it covered in dew on my way back home, in the early morning. The Maasai ol'oiboni, or shaman-healer, uses it as a way to bless and protect those who have come seeking health. Dipping the fresh plant fronds in raw milk, he sprinkles the petitioner with the magical infusion, releasing negative influences and promoting wellness and growth. May your life be blessed. May no thorns find your feet. And may you have joy in simple things, wealth in those you love.

Herb Power: find your wild ally this summer



Recently, scientists uncovered the remains of a Neanderthal tribe that lived in the area now known as Spain, some 50,000 years ago. Analyzing residue on their teeth, the researchers discovered traces of powerful chemicals: triterpenes and lactones from chamomile and yarrow were still detectable, and indicated that these early hominids consumed these plants, which have little or no caloric value. It’s an intriguing finding: have we been harnessing the power of herbs for that long?

In fact, we may have been herbalists well before we were human – from an evolutionary perspective, at least. Primates are the most enthusiastic, but many other species (from bees to elephants) employ plants just as the Neanderthals seem to have done: small quantities of wild botanicals that have little caloric value are used, deliberately and effectively, to maintain health. While lacking an understanding of physiology and biochemistry, animals (and early humans) still realize that renewing a connection to the wilder side of the dinner plate is a daily necessity.

Christina Warriner studies archaeological evidence to piece together a picture of what how our oldest ancestors nourished themselves. She has come to three basic conclusions: first, ancient diets were incredibly diverse. They were different from region to region, from season to season, and featured a vast amount of different plants as well as some meat and animal fat. Second, all those plants came in small, frequent doses, and included herbs that were relatively “calorie-poor” (as we saw in the Neanderthals). Finally, the plants our ancestors consumed still had large amounts of phytochemicals – plant constituents with biochemical action and that have been largely bred out of modern vegetables. The plants we used to eat had strong, often bitter flavors, were hard to find in quantity, and were – to put it simply – powerful.

What happened? Over all these years, we’ve drifted away from these plants. The diversity of our diet is at an all-time low, starring only corn, wheat and soy (along with traces of other, highly hybridized, veggies). We eat lots and lots of these plants, and almost none of the “calorie-poor” herbs that have been animals’ companions for millions of years. The chemical potency of our dietary plants is all but gone, bred out because of its unpalatable flavor. Many have been telling us that the “Western” diet is killing us slowly, and lies at the root of the modern epidemics of mental and spiritual distress, digestive disease, cardiovascular illness and cancer. They warn us to turn our backs on the modern foods we’ve grown accustomed to – and that our lives may depend on it.

If you’re into herbs, you may have a different take.  It may be possible, and in fact preferable, to restore diverse, wild, powerful botanical chemistry into our daily lives and, by so doing, circumvent the risks of the “Western” diet. It may not be that wheat, soy and corn are killers: it may just be that, without our old allies, our bodies have forgotten how to work properly. They are out of context. And wouldn’t it be great if, by bringing that context back, we could enjoy a modern, urban life without the risks and diseases associated with it? That is precisely what herbs can offer us: they are easy to grow, simple to prepare, and deeply nourishing, enlivening, and restorative when consumed habitually. They provide the context our physiology needs, while linking us back to the wilder side of nature. This wilder side is calling us: it’s green, open, sexy and powerful. With it, we are at our most vibrant.

So herbs are radically different from drugs: they are more akin to physiologic building blocks, the vectors for cross-kingdom signaling, a way for plants to guide us to our best potential. While some can definitely treat disease and infection in the short term, herbs really shine at slowly rebalancing us in our entirety, so that mental distress, spiritual malaise, toxicity and inflammation melt away like snow in warm sunlight. The safe medicinal herbs are often weedy, or at least ridiculously easy to grow, and their preparation and administration are simple and worry-free. And think about what happens when you start to see a dandelion as more than just a pest: could it be an old friend? Could it have something in it that we lack, that used to be as familiar as electricity is today? Strange things start to happen to our ecological and cultural outlook when we begin to ponder these questions.

This is what I encourage you to do: find a wild plant, maybe one with a historical record of medicinal activity, to be your ally this summer. Identify it with certainty, make sure it’s safe. Watch it grow, slowly at first, then faster as it bursts into flower, sets seed, matures its root. Taste it. Harvest it. Sit with it on sunny mornings and through rainy afternoons. This medicine is very real, but it is also very different. If you want to find the true power of an herb, you will have to approach it as a friend, not as an alternative to a pill. In so doing, you won’t just discover medicine. You will come home, too.

Plant allies for winter health


Enhancing immune activity

Why: Herbal allies to combat respiratory infection as it begins.

Echinacea, Andrographis, Elderberry, Hyssop, Garlic, Osha

These agents provide an immediate “boost” to immune function, particularly the body’s ability to produce antibodies against viral infections. Will shorten the duration of common winter infections, and can also be used longer-term as preventative agents particularly for those more at risk.

How to take: most acute-use antiviral herbs can be taken whole, or with minimal processing. I often will simply nibble on a small (1”) piece of Echinacea root, or an even smaller piece of Osha root, when the first warning signs of illness begin. Stored in a glass mason jar in a cool cabinet, they will keep at least a year.

Elderberry seems best taken as a syrup. These preparations are pretty widely available, or you can make your own by mixing an equal volume of fresh berry juice with raw honey, and storing in the fridge. The honey is really medicinal too! 2 TBS three to five times daily is typical.

Andrographis is extremely bitter and hard to take straight. Often, we recommend a tablet or capsule of this plant, at a dose of 400mg three times a day, again at the first signs of trouble.

Hyssop makes an excellent though somewhat biting tea, and Garlic can be included with food (though the more raw, the better).


“Deep” immunity

Why: Enhancement of our own immune function, to clear infection more quickly if it does begin, and help get rid of lingering problems or break the pattern of repeated illnesses.

Astragalus, Medicinal mushrooms, Spikenard, Tulsi

Good policy for anyone, these tonics are most indicated in conditions of convalescence, to rebuild strength, or in cases of repeated infection every season. Taken consistently, they will also improve immune activity, helping to shorten lingering colds and flus, and prevent them to begin with.

How to take: these herbs are an easy addition to your regular stock-making routine. If you’re not making stock regularly (once a week or so), consider doing it! Save your vegetable scraps and peels and any animal bones, and simmer them with Astragalus root ( ½ cup per gallon), dried mushrooms (Reishi, Turkey Tail, about ½ cup total per gallon) and some spikenard root (Aralia racemosa, about 2 TBS per gallon). This last one is especially indicated to help bring up vitality and kick out lingering congestion. Also, see a specific recipe variant in the “recipes” below.

Tulsi (aka Holy Basil) is a wonderful tea herb. Start it up in September if there are concerns about the coming season.



Adjusting mucous membrane function


Why: Our respiratory mucosa is our first line of defense. Ensuring it is not swollen, stuck, and/or inflamed not only improves symptoms immediately, but also improves defense.

Reducing swelling: Goldenseal, Barberry, Osha
Reducing thick secretions: Echinacea, Horseradish
Reducing dryness and irritation: Propolis, Licorice

How to take: These strong herbs usually don’t require a high dosage to accomplish their goals. Part of this may be due to the fact that reflex action mediates their effects – horseradish makes your eyes water, for instance, even though none is ever put in your eyes. So I usually suggest tinctures, good to have on hand and already picked out depending on what your respiratory passages tend to feel like when you get sick. Of these liquid extracts, try taking 15 drops or so every couple of hours and seeing how it makes you feel.


Protecting and toning the respiratory tract

Why: If lungs are consistently affected. This isn’t an issue for everyone, but if it tends to be, best to include these herbs right away before the illness gets there.

Thyme, Garlic, Usnea

These herbs are especially useful for those whose lungs are prone to weakness (history of pneumonia, repeated bouts of bronchitis or bacterial infection, or smokers).

How to take: Thyme can be inhaled as a steam by brewing strong tea and breathing deeply. After that, go ahead and drink the tea too! With a little raw honey. Usnea lichen is eaten whole, or taken as a capsule – though I really like the effect of the raw herb as it goes down the throat. It kills viruses and bacteria that contribute to sore throat, and enhances lung immunity once you absorb it internally. 1-2 grams of Usnea twice daily is usually plenty.


Encouraging lymphatic activity

Calendula, Cleavers

Useful in the latter phases of an illness, after the fever or acute symptoms have abated, to clear lingering inflammation and hasten recovery. Can also be used right at first if there is a history of lymph node (gland) tenderness.

How to take: Most often as teas. The extra fluid is really helpful too. 4-6 TBS per quart of water.


Encouraging circulatory activity


Ginger, Garlic, Cayenne

This often is all you’ll need for a common cold in those of strong constitution. Helpful for all to stimulate warmth, encourage perspiration and speed recovery, but particularly indicated in a colder person.

How to take: Special hot sauce? Or a home-made version thereof where the above three herbs are blended, to taste, with apple cider vinegar. Try ½ teaspoon twice a day to start.



Herbal Recipes for Winter Health

Remember that, when using herbs for healing and wellness, it is important to bring their powers into your life from many different angles – use a tea, tincture, and/or an aromatherapy steam to reinvigorate a weak constitution, and think preventatively to strengthen immunity during times of good health.

Immune ‘soup’:

This simple blend can serve as a base for any soup, or can be taken ‘as is’. It strengtens the immune system and can help prevent weakness during the winter months. It is quite powerful, but as with any herbal tonics (blends designed to strengthen over the long term) it is best used on a regular, daily basis.

Astragalus (Astragalus membranaceus) root 1 cup of dry root

Ashwagandha (Withania somnifera) root ½ cup dry root

Red Reishi (Ganoderma lucidum) mushroom ½ cup dry mushrooms

Burdock (Actium lappa) root ½ cup dry or fresh root

Garlic (Allium sativum) bulb 4 minced cloves

Take the above ingredients, and simmer them, covered, in a pot with 2 quarts of spring or well water (this process is called a decoction). Simmer on very, very low heat for at least one hour (in China, these types of tonics are often simmered for a whole day – a crock pot can be helpful. Be sure to keep an eye on the soup, and add water as needed. Don’t scorch the pot!). Strain and serve, perhaps with a little honey, or freeze for storage. The daily dose is 8 fluid ounces (1 cup).

Get creative with this soup! Add onions, carrots, seaweed (dulse, arame for example) and salt to taste. You can also add cabbage, potatoes, and cooked beans to make it more of a hearty meal. Or herbs and spices like Cayenne, Thyme, and Parsley. These soups remind us that our daily food is our best medicine!



Tea #1 – For lung congestion

Sometimes a cold can ‘go down’ into the lungs, making it difficult to breathe and producing a deep and sometimes painful cough. In these cases, this blend can help.



Mullein (Verbascum thapsus) leaves 3 Tablespoons dry leaves

Thyme (Thymus vulgaris) leaves 1 Tablespoon dry leaves

Licorice (Glycyrrhiza glabra) root 1 Tablespoon dry root

Ginger (Zingiber officinalis) root powder 2 Teaspoons dry powder



Place all the ingredients in a teapot or mason jar, add 1 Quart of boiling-hot water, cover, and steep for 15 to 20 minutes (this process is called an infusion), then strain. Drink the whole quart over the course of a day. You can prepare this tea the night before, and let it steep all night if you’d like, but I have found that teas for colds and flus work better if you drink them hot.

Add honey to taste.




Tea #2 – For nose and sinus congestion

Often times the worst part of a cold is a stuffy nose. This blend can help relieve that congestion, drying up the nasal passages a bit. It is also useful, I’ve found, after the worst of a cold or flu is done, to help relieve lingering symptoms of congestion.


Elder (Sambucus nigra) flowers 2 Tablespoons dry flowers

Red Clover (Trifolium praetense) flowers 2 Tablespoons dry flowers

Catnip (Nepeta cataria) leaves 1 Tablespoon dry leaves

Ginger (Zingiber officinalis) dry root powder 1 Teaspoon dry powder

Place all the ingredients in a teapot or mason jar, add 1 Quart of boiling-hot water, cover, and steep for 15 to 20 minutes (this process is called an infusion), then strain. Drink this quart of tea over the course of 4 hours, then repeat if necessary. You can add a little honey to taste if desired, although I’ve found too much sweetness can make nasal congestion worse.




Tincture – Echinacea purpurea

Tinctures are alcohol-based extracts of herbs. Usually quite potent and concentrated, they require a solvent such as Vodka to create. The dose is usually much, much smaller than that of a tea.

Echinacea (Echinacea purpurea) root 2 or 3 Tablespoons fresh or dry

Vodka (100 proof) 8 fluid ounces (1 cup)

Chop the root as finely as is possible, and place it in a jar you can close securely (mason jars work well, I’ve found). Pour the vodka over the chopped root, close the jar, and shake it really well for at least 30 seconds. Label your tincture (name of herb and date are the mimimum requirements) and put it in a cool, dark place. Shake it well at least every other day.

After two weeks (better yet, wait four weeks if you can), strain your tincture, discard the spent roots, wash out the jar, and put the tincture back in. It should have turned a nice reddish-brown color, and is ready to use!

Echinacea tincture is taken 1 teaspoon at a time, in a little water, once every hour when you feel the first signs of a cold or a sore throat.




Aromatherapy steam

This process is very useful to help relieve congestion in the nose and lungs. Usually best to do at night, before bed, to clear the breathing passages and encourage restful sleep.
Boil a pot of water. When the water is hot, remove from heat and place it on a safe surface (a stone or trivet works well).
Add 2 drops each of these essential oils (highly concentrated plant essences – use only a few drops, never internally, and be careful because, undiluted, they can irritate the skin):
Rosemary
Thyme
Eucalyptus
Cover your head with a towel and breathe in the steam for 5-10 minutes.

Love, Fertility and Reproductive Health

The traditional strategies for enhancing libido and improving lovemaking usually involve two components: stimulate circulation and good blood flow to the erogenous zones of the body, and relax the mind so it can shed the cares of the day. Many of the traditional aphrodisiac plants hit either one or both of these bases!

For a really healthy love life, consider a shared exercise program as well. Men who exercise regularly have much lower incidence of erectile dysfunction – and the same goes for women whose libido may be suffering.

Finally, if fertility for men or women is an issue, consider adding some simple and safe herbal adaptogens with affinity to the reproductive organs into your daily habits. Shatavari for women, rich in plant estrogens, can support healthy ovulation and encourage conception. And Maca for men can increase sperm counts and motility. Taken daily, these plants can make a difference if part of a comprehensive fertility protocol.

Aphrodisiac “Bliss Balls” Recipe:

Mix together:

1 ½ cup almond butter

1 cup honey

Blend together and slowly add to the honey/butter mix:

2 cups cacao powder

2TBS Ashwagandha root powder

4TBS Maca root powder

2TBS Muira Puama bark powder

2TBS Shatavari root powder

Roll into balls about 2 inches in diameter. You can then dust them in cocoa powder or roll them in dried shredded coconut or dehydrated crushed raspberries



Valentine's Hot Cocoa


Prepare an infusion (tea) with:

About 1 teaspoon of Damiana leaves

About 1 teaspoon of crushed Rose petals

A trace of Cayenne if desired

Steep for about 5 minutes, then strain. Add:

1 TBS Cocoa powder

1 teaspoon (or more to taste) of Honey

Stir well and enjoy warm!

The above amounts are for 1 cup. Scale up for multiple cups.


Maca, Lepidium meyenii

The root of this perennial plant comes to us from the Andes of South America, where its extremely nutritious tuberous taproot serves as a food and general tonic. Recently, it has gained a reputation as an aphrodisiac for men and women, enhancing circulation, improving the quality of spermatic fluid, and positively affecting the central nervous system with its relaxing yet invigorating qualities.

Muira puama, Ptychopetalum spp.

Also known as “potency wood”, the bark of this Amazonian shrub has a stimulant and aphrodisiac quality, which increases circulation and enhances libido in both sexes.

Shatavari, Asparagus racemosus

The root of this cousin of garden Asparagus comes to us from the Indian subcontinent. It is juicy and demulcent in quality, increasing lubrication and quality of sexual fluids for men and women, though it’s traditionally thought of as a woman’s herb. It is also known as “she of a hundred lovers”, but its powers are not limited to improved sexual function: it also functions as an adaptogen, lessening the effects of stress and tension on the human system.

Ashwagandha, Withania somniferum

Another plant from the Indian Ayurvedic tradition, this root of the nightshade family is also known as “horse root”, a reference to stamina and perhaps to sexual function as well. It is another excellent adaptogen that leaves the system more resistant to stressors of many types, though it has a specific affinity to help those who are having trouble relaxing into sleep or lovemaking.

Cacao, Theobroma cacao

Theobroma means “food of the gods”, and chocolate fits the bill more than anything else on earth. Its uplifting and gently stimulating quaility is due to a precise cocktail of alkaloids that bring about a gentle euphoria and relaxation. Additionally, it enhances circulation and protects the cardiovascular system, increasing blood flow to the sexual organs while it enlivens and thrills the mind. Plus, with a little sweetness, it’s delicious!

Damiana, Turnera diffusa

Another herb from that magical cradle of power in Central America, Damiana has a totally unique flavor that is minty, spicy, and slightly bitter. It invigorates the circulation and improves sexual function while lessening the effects of the anxieties and tensions of the day.

Spring Tonics!

Traditionally, the days around the Vernal Equinox (mid to late March) and the month(s) after it were seen as a time of intense, rushing energy: days get longer and the sunlight more intense, the first signs of green growth emerge, and wildlife stirs again. Herbalists still consider this a time when the more inward, ‘congealing’ energies of Winter begin to transition into the more outward, ‘expansive’ energies of Summer – and when a little attention paid to the process can improve vitality, strengthen digestion and immunity, and keep us in tune with the changing seasons.
There are specific herbal allies that have gained a deserved reputation for aiding in this transition, and each has its own peculiar “virtues” and affinities. All, however, rely somewhat on two basic strategies: either enhancing digestive and eliminative function, or bolstering the power of the body’s immune and hormonal systems. Some do both! And generally, it was (and still is) considered a good idea to start with enhancing absorption and elimination, and then proceed with strengthening the underlying physiology.
The old recipes for “root beers” can be somewhat instructive in this regard: they often feature a combination of bitter roots (which enhance elimination) coupled with aromatic, sometimes pungent ingredients (which improve digestion) and hormonal tonics (to enhance energy and vitality). Many of the herbs and botanicals listed below can be combined along these lines to make a customized spring tonic for yourself or your friends and family, helping to ride along the tides of Spring and get ready for Summer.
The last detail in the herbalists’ crafting of vernal concoctions is an attention to the constitution and physiological peculiarities of the individual using the tonic. Generally, these are pretty obvious considerations – but one point to remember is to try to add “cooling” herbs for those expressing signs of overactivity, heat, and inflammation; and “warming” herbs for those showing signs of sluggishness, depression, chill, and frequent infections. Often eliminative herbs are more cooling, and tonic herbs more warm. Botanicals listed below have their traditional energetic value added as a start in this process.

Tree sap

Often from maples (Acer saccharum, and other species), the sap of Birches (Betula spp.) can also be used. I like to use the unheated, unfiltered sap as a tonic all by itself: this “tree juice” provides unaltered enzymes as well as sugars and minerals ready for optimal absorption. It can also be used as a base for decocting (simmering) some of the roots and barks described below. Usually, a pint to a quart daily is consumed – though more is not necessarily a bad thing! Alternatively, you can reconstitute a similar liquid by using about a tablespoon of maple syrup per pint of spring water.


Burdock (Arctium lappa)
This root, generally cooling in energy though somewhat tonic too, can be eaten as one would a carrot, or simmered into a tonic brew. It is best suited for those with dryer skin, and perhaps an underactive appetite. Its chief traditional use is for acne and other skin complaints. Use about 2 TBS per pint of water, along with other herbs.

Dandelion (Taraxacum officinale)
A true remedy that synergizes well with herbs for almost any ailment, Dandelion is a catalyst for change that gently and safely enhances digestive and eliminative function. When in doubt, this is the root to pick! Its yellow flowers remind us early on that it’s time to pay a little attention to our bodies this time of year. The root’s energy is somewhat cooling, and it enhances detoxification through the liver, helping to resolve gassiness and sluggishness that may have accumulated after a winter of congestive, thick foods. Use about 2 TBS of chopped root per pint of water.

Yellowdock (Rumex crispus)
These roots are more bitter, and are best for those who might have a tendency toward constipation. They combine well with any of the other cooling, bitter roots and improve liver function and elimination. Generally, I suggest using Yellowdock for shorter (1-2 weeks) periods than Dandelion or Burdock, but it is still quite a safe plant. 1 TBS of chopped root per pint is usually adequate to relieve somewhat sluggish digestion.

Echinacea (E. purpurea, E. angustifolia, and others)
This is a cooling, dispersive root that posesses a good degree of pungency as well. Its chief use as a springtime tonic is to help boost immunity, especially if there are or have been any swollen glands or recurrent respiratory infections associated with winter illness. It can also help dry, scratchy throats that sometimes linger into spring. While I often recommend an extract, the roots are excellent too provided they are simmered for a little while (10-15 minutes). This time of year the plants are just starting to poke up from the soil, making it easy to find and dig out of the garden. Use 2 TBS of chopped root per pint of water.

Wild Sarsaparilla (Aralia nudicaulis)
An abundant relative of Ginseng, this plant posesses starches and bitter saponins that counteract fatigue and gently warm the system to enhance vitality and elimination at the same time. It also has hormone-balancing effects, especially in relation to stress hormones, making it a good adjunct for those who have intense work or personal lives, or who rely heavily on stimulants. It is a little difficult to recognize and find early in the season, before the greens emerge, so marking it out in the fall can help with digging the long rhizomes in the spring. Use a piece or pieces of rhizome about the length of your index finger in a pint of water.

Spikenard (Aralia racemosa)
Another Ginseng relative, this is a sweet, spicy and warming root that is most indicated as a tonic for hormonal and respiratory function, particularly for those with chronic lung congestion. Use only 1 TBS per pint – it is a potent ally.

Dwarf Ginseng (Panax trifolius)
Also called groundnut, this is a nourishing and rebuilding tonic that is somewhat rare in the wild, so it should be used judiciously. It flowers early in the spring, and though only a few inches tall, packs a flavor and power that is quite excellent for warming deficient constitutions that have become sluggish and undernourished over winter. If you find a good stand of it (make sure you have the correct plant ID!), you can have one corymb (a round, underground “bulb” attached to a delicate white root) two or three times a week eaten raw, straight from the forest floor, or simmered into your tonic brew.

Goldthread (Coptis canadensis)
This is a very bitter, cooling, detoxifying and anti-inflammatory plant that you really don’t need a lot of. It chief indication is chronic inflammation, perhaps also involving the skin, and a more “oily” skin pattern that could benefit from drying. It enhances digestive function when taken before meals, improves sluggish bowels, and clears heat that settled into joints and muscles over the winter months. Some have reported an improvement in allergies and sensitivities. It is also evergreen, which makes it easy to find even under a little snow cover! Its thin rhizome is bright yellow, and the above-ground greens are useful too. Use one to two plants (4-5 inches of root total) per pint of tonic brew.

Sarsaparilla (various Smilax species)
Not a local Vermont plant, the root bark from this vine is still such a classic spring tonic that it bears mention. It has a distinctive, warming and spicy flavor that, while enhancing digestion, is most powerful at adjusting hormonal balance (thyroid, adrenal, and reproductive hormones) and I have always found it useful for stubborn skin conditions such as eczema and psoriasis (often worse after the dry indoor heat of winter). Sarsaparilla has a strong flavor, so experiment with taste until you find what you like. It is usually available at the herbs store; start with ½ to 1 TBS per pint.

Sassafrass (S. albidum)
The FDA doesn’t appreciate the use of this bark anymore, due to its safrole content, which is considered carcinogenic. Its distinctive spicy/sweet and warming flavor and energy make it perhaps the most classic “root beer” ingredient, evoking memories of times when there brews were actually made from plants… And, for a few weeks each spring, consuming sassafrass provides such a negligible amount of safrole that, truly, doesn’t compare to pumping gasoline in terms of cancer risk. I would use about 2 TBS of dry bark per pint of brew, but I really like the flavor. Experiment and add to taste.

Cleavers (Galium aparine)
This green, as well as its cousin sweet woodruff, comes out a bit later in the spring but makes an invaluable cooling tonic for folks who are prone to swelling from chronic inflammation, edema, or water retention. They can be juiced and an ounce of juice taken as a daily tonic, or steeped into a more complex tonic after roots have been taken off the fire. Use about 2 TBS of chopped herb.


Nettles (Urtica dioica)
Though green, this herb is actually a bit warming and drying. It is great for those who show signs of water retention (sometimes evidenced by a swollen, “scalloped” tongue), or those in need of iron and other nutritive minerals. Finally, its mildly detoxifying qualities can help in seasonal allergies. Herbalists use the young, fresh leaves in soups or steeped into an herbal brew after the roots are done simmering – about 2 TBS or more of chopped leaves per day.

Dandelion greens (Taraxacum officinale)
We would walk through the meadows, before they fully became green with grass, looking for the young rosettes of dandelions and collecting them whole, along with the crown of the root. Back home, my aunt would dress them with olive oil and wine vinegar, for an abundant (though bitter) spring salad. These greens improve digestion, enhance elimination through the kidneys, and are loaded with important minerals. Their reputation for cooling overheated constitutions extends to the cardiovascular system. They are excellent eaten fresh as part of salads or wilted in soups or stir-fry; alternatively, steep 2 TBS of chopped leaves into an herbal brew after the roots are done simmering.

Mustard greens (Brassica species)
There are a wide range of mustards that come up quick in springtime, since they are so tolerant of late frosts. They are warm and spicy, wake up the digestion and liver, and additionally contain compounds that show much promise in preventing and treating cancer. Of course, they are best as part of a wild food salad, or cooked in soups (though they lose a lot of pungency if cooked). I don’t normally brew these into tea.

Wintergreen (Gaultheria procumbens)
This is a very aromatic and cooling plant, rich in anti-inflammatory salicylates and endowed with wonderful flavor, another aroma often found in classic root beer preparations. It is a good digestive normalizer, especially if there is a lot of gas, bloating, and irritation; it can also help with chronic inflammatory conditions of the joints and back especially if these get worse over the more sedentary winter months. Steep 5 or 6 fresh leaves in 8oz of herbal brew, covered so as to not lose the volatile aroma, and do not boil!

Birch bark (Betula species)
The black birch is perhaps the most flavorful, but the bark of any species yields a wintergreen-like essence that is similarly cooling, and much more readily available. Use a good handful of crushed bark (perhaps a cupful) per pint of water, and add it to your brew for the last two or three minutes of simmering.

A note on preparation
Many of the plants mentioned above release their medicinal constituents during a process of light simmering, known as “decocting”. The resulting brew is often called a “decoction”. It is best accomplished by simmering the herbs in a stainless steel container, covered, for 15 minutes or so on low heat. Afterwards, the brew can be removed from the heat and more delicate greens added and left in the pot, covered, for another 10-15 minutes or so. Finally, strain the brew and drink immediately, or bottle for 1-2 days.
