Now that Iâ€™m living on my home ground again, Iâ€™ve been feeling like writing about some real traditional Appalachian herbs. So for Julyâ€™s berry-themed blog party, I chose a classic of Appalachian herbalism: pokeberry (Phytolacca americana).
A while back on the Herbwifery Forum, a few of us were reminiscing about growing up in West Virginia and North Carolina. From our informal survey, it seems like covering oneself in pokeberry juice and running around like a little demon is an essential part of an Appalachian childhood. And itâ€™s no wonder. Pokeweed is everywhere in Southern Appalachia, and the ripe berries hang in shiny, inky purple-black clusters. Squish them in your hands, and they turn bright pink. What could be more fun?
Of course, we all knew that pokeberries were â€œpoison,â€ so we didnâ€™t eat them. (Unless someone said â€œI dare you,â€ that is. And even then weâ€™d spit them right out again. I never knew anyone to get sick on them.)
The truth is, poke is strong stuff. It can be toxic even in moderate doses. Some herbalists stick to diluted homeopathic preparations of the plant, just to be on the safe side. But I prefer the old-fashioned way: drops of the tincture, spoonfuls of the decoction, sips of the wine, or a berry at a time. (Fresh plant only. Poke doesnâ€™t take well to drying.)
So you might be asking, like my ten-year-old niece always does, â€œWhatâ€™s it for?â€ Well, poke is for all things, um, pokey. Poke gets things moving in the body, especially the lymphatic system, the joints, and the metabolism. In other words, it’s an “alterative.” Used externally, it kills things (scabies, ringworm, etc.).
The most common indications for pokeberries in old-time Appalachian herbalism were â€œrheumatismâ€ and â€œbad blood.â€ These days Iâ€™d call those â€œchronic joint painâ€ and â€œlymphatic sluggishness.â€ The usual prescription was to eat one berry a day for a week (without chewing the seeds), stop for a week, and repeat. Three berries, three times a week was another classic dose.
This tradition of on-and-off dosing is interesting. Perhaps poke inspires a reaction in the bodyâ€”maybe in the immune systemâ€”that is triggered only by withdrawal of the dosage? Poke is often called an “immune stimulant,” but I imagine it’s more complicated than that. I often wonder about pokeâ€™s effects on autoimmune conditions, since many of the conditions associated with the symptoms of â€œrheumatismâ€ turn out to have links to autoimmunity.
Modern herbalists sometimes use pokeberries to help stimulate an underactive thyroid, and old texts often mention goiter and obesity as important indications for the plant. Itâ€™s possible that poke acts directly on the thyroid, or indirectly on the metabolism through its general stimulation of â€œmovementâ€ in the body.
Pokeâ€™s movement-stimulating properties, combined with its affinities for the lymphatic system and â€œglands,â€ have led to its traditional use for many conditions involving hard, swollen masses in the body, including simple swollen lymph nodes, mumps, tonsillitis, adenitis, orchitis, mastitis, goiter, and cancer.
In my experience, poke root is one of the best things out there for inflammations of the breast, including mastitis. Fresh root poultices are traditional (though they can cause skin irritation), but tincture of the fresh root or a plaster of fresh berries will work, too, along with drop doses of the tincture internally. (Poke is contraindicated during pregnancy, but okay for nursing momsâ€”in small doses, of course.)
One of pokeâ€™s many folk names is â€œcancer root,â€ and (like many other lymphatic herbs) it has a reputation as an old-time cancer remedyâ€”especially for breast and skin cancers. Itâ€™s interesting that the old authors are split on its effectiveness. Iâ€™ve noticed that those who recommend poke for cancer support tend to emphasize using the fresh plant, rather than dried. This fits with what Iâ€™ve been taught. Always use fresh poke.
Whiskey tincture of the fresh root and fresh berry wine are the traditional Appalachian ways to preserve the plant for internal use. Traditional preparations of poke for external use often involved extraction in kerosene. This is one tradition I donâ€™t follow. Poke-infused olive oil works just fine, thanks.
My favorite saying about poke comes from Tommie Bass. Talking about the old-time use of poke whiskey as a tonic, he said “It just straightened you out.”
An herbalistâ€™s cheat-sheet for poke:

Have fun “poking” around!
PS: I’m going to post this month’s blog party on August 2ndâ€”mainly because that’s the day we get real internet access at our new house, but also because it gives busy-in-the-summer folks an extra day to make a blog party post!
