Pokeweed is a perennial herb that is native to eastern North America and cultivated throughout the world. It can grow to a height of more than ten feet during the summer and dies back to the root each winter. The berries and dried roots are used in herbal remedies.
Some research has shown that a protein contained in pokeweed, called pokeweed antiviral protein (PAP), has anti-tumor effects in mice and laboratory studies. In test tube studies, PAP has also shown action against viruses such as herpes and human immunodeficiency virus (HIV). Clinical trials have not yet determined whether these effects apply to humans. All parts of the mature pokeweed plant contain chemically active substances such as phytolaccine, formic acid, tannin, and resin acid. All parts of the plant are at least mildly poisonous when eaten, although the root is most toxic.
How is it promoted for use?
Proponents claim that pokeweed can be taken internally to treat a number of conditions, including rheumatoid arthritis, tonsillitis, mumps, swollen glands, chronic excess mucus, bronchitis, mastitis, and constipation. They also say that the herb is an effective treatment for fungal infections, joint inflammation, hemorrhoids, breast abscesses, ulcers, and bad breath. Herbalists also claim that external application of a preparation made from the plant relieves itching, inflammation, and skin diseases.
