Arctostaphylos uva-ursi
Uva ursi is an evergreen shrub found in northern latitudes, long used by Native Americans and European herbalists for urinary tract conditions. Its primary active compound, arbutin, is converted to hydroquinone in alkaline urine, providing antiseptic action specifically in the urinary tract.
Uva ursi (Arctostaphylos uva-ursi) is an evergreen shrub traditionally used by Native Americans and Europeans as a urinary tract antiseptic. Its primary active compound, arbutin, is converted to hydroquinone in alkaline urine, providing localized antimicrobial action. It is commonly used for uncomplicated urinary tract infections, cystitis, and urethritis, but its use is limited to short-term therapy due to potential toxicity.
Arbutin, a hydroquinone glycoside, is absorbed and excreted unchanged in urine. In the presence of alkaline urine (pH > 7), β-glucuronidase and bacterial enzymes hydrolyze arbutin to hydroquinone, which exerts bacteriostatic and bactericidal effects against common uropathogens such as Escherichia coli. Additionally, ursolic acid and tannins provide mild anti-inflammatory and astringent actions, reducing mucosal irritation. The herb also exhibits weak diuretic effects via increased renal blood flow.
