Uva ursi is an herbal extract derived from the leaves of the Arctostaphylos, a small evergreen shrub, which has been used in Native American traditional medicine for treatment of urinary tract symptoms and as a diuretic.
Uva Ursi extract is standardized to 20% arbutins.
Based on the antiseptic action of the leaves, Uva Ursi was listed in the U.S. Pharmacopeia and National Formulary from 1820-1950.
