Uva Ursi is a an evergreen shrub that grows in alpine forests in many regions, including North America, Europe, the Iberian Peninsula, Siberia, and the Himalayas.  It produces bright red or pink berries that are edible (but sour) that bears like to eat, leading to its common name of Bearberry. Uva Ursi has been used medicinally since the 2nd century, and Native Americans used it for urinary tract infections.

Uva Ursi contains tannins that have astringent effects, helping to shrink and tighten mucous membranes in the body.

Uva Ursi is used in health supplements today to help manage bacteria in the urinary tract.
