What is a Uva Ursi Leaf? The herbal supplement known as uva ursi (UU) is derived from an evergreen shrub that bears red berries. It is sometimes known as bearberry, even though there are only two species of uva ursi, a word that refers to a group of unrelated but related plants of the genus Arctostaphylos. The little, evergreen plant known as uva ursi (Arctostaphylos uva-ursi) has orange berries. The leaves have long been used in traditional medicine. Urine flow may be increased and germs in the urine reduced using uva ursi. It seems to lessen edema as well. Bears are highly fond of the uva ursi fruit. "Bear's grape" is what the Latin term "uva ursi" implies.
