## Medicine

Epilobium montanum herb has been used in the traditional Austrian medicine internally as tea for treatment of disorders of the prostate, kidneys, and urinary tract. A review of studies of the use of extracts from Epolobium species indicated that there was some evidence for traditional uses with digestive disorders. The extracts contained mixtures of flavonoids, phenolic acids and tannins, with the tannin oenothein B possibly a major contributor to biological activity. There was not sufficient evidence of efficacy in prostate disorders.
