UVA URSI, Bearberry Leaf, Uvae ursi folium, Arctostaphylos uva ursi (L.) Spreng, family Ericaceae. The dried leaves constitute the drug. Besides arbutin (not less than 8%) and methylarbutin, the leaves also contain tannins. 1.5-4.0g dried leaves given by infusion three times daily gives an antiseptic effect (by hydrolysis to hydroquinone) in the urinary tract, when the urine is kept alkaline. The maximal antibacterial effect is reached about 3 hours after administration.
