Uva Ursi Overview
Uva ursi, also known as bearberry, is a plant species belonging to the Ericacea family, and is native to North America, Europe, and parts of Asia. It is a low-growing shrub with small, white flowers and edible red berries. The leaves of the plant are often used in traditional medicine as they are thought to have various medicinal properties, such as astringent, diuretic, and antimicrobial effects.
Medicinally, Uva ursi is most often used to treat urinary tract infections and other urinary problems, as well as skin conditions such as eczema and dermatitis. It is also sometimes used to promote weight loss and as a natural remedy for kidney stones. In dietary supplements, Uva ursi is often standardized with a specific amount of Arbutin (usually around 20%), a constituent of the plant.
