? Food supplement
Birch bark has been shown to act as a laxative and diuretic, and many consume it orally to treat their gout, rheumatism and kidney stones. In fact, one of the plant's chemical components, Betulinic Acid, is currently being tested as a promising cancer treatment. The water soluble form of the acid inhibited the growth of human prostate cancer cells by nearly 96%, according to a Weill Cornell research team. Some researchers believe that it has the ability to destroy tumor cells and slow the growth of both HIV and melanoma.
