BERBERINE
Why you want it: With actions similar to penicillin and amoxicillin, it is used for treating cholera, acute dysentery, diarrhea, E. coli, infected wounds, giardia, and yeast infections.
While there are not as many uses for extracts from berberine plants as for juniper and Usnea, a berberine tincture is still very nice to have on hand in case of cholera or giardia. The most common plants high in berberine content are Japanese barberry, Oregon grape, Nandina domestica, Hydrastis canadensis, and Phellodendron amurense (not to be confused with the common philodendron houseplant). And you’ve probably got some growing near your home or in a local shopping center parking lot. Japanese barberry (Berberis thunbergii) is extremely common in the West as a landscaping shrub. In the East, it propagates like blackberries and raspberries, which is to say it is very invasive. Oregon grape (Mahonia aquifolium) and Nandina domestica, also both very popular landscaping ornamentals. Medicine from all of these plants is equally effective. It’s extracted from the roots of the first four species listed; however, from the latter, Phellodendron amurense, the medicine is extracted from the inner bark.
To make the medicine, first target which plants you will be using. (Don’t do this on private property unless our society has truly collapsed.) Check for berberine content by scratching off the outer bark of one of the lower branches. The inner bark has to be yellow. If there is no yellow, the plant does not have adequate levels of berberine, and you should move on to another plant. In the fall dig up the roots of any of the above-listed plants or use the inner bark from Phellodendron amurense. Japanese barberry roots are going to be quite tough, and it would be best to cut them into 0.5 to 1 inch pieces before they dry. Oregon grape roots aren’t so difficult, so if you’ve got the option, go with Oregon grape.
Tincture: Tincture the dried root in a 1:5 ratio (1 part herb by weight to 5 parts alcohol by volume) in 50 percent alcohol (100-proof vodka is a good choice). The dosage is 10-60 drops, 3 times per day, or more in acute gastrointestinal conditions. Because we have a very well developed pharmaceutical industry in this country, berberine just isn’t used all that much in the US. Very little information is available on dosages to treat various conditions.Continue reading“The Pharmacy Around Us – Part 2, by Jen R.”
