Uva Ursi

Herbal Supplements

Uva ursi, derived from the leaves of Arctostaphylos uva-ursi, has a long history of traditional use in supporting urinary tract health. Research suggests that its key compound, arbutin, is converted in the body to hydroquinone, which appears to exhibit antimicrobial properties within the urinary tract. Studies indicate that uva ursi leaf extract may help maintain a healthy urinary environment, particularly when urine is alkaline, as this seems to enhance the activity of its beneficial compounds. While the traditional use is well-documented and some clinical research is encouraging, the body of evidence is still evolving, and most researchers agree that further well-designed trials are needed to fully understand its effectiveness and long-term safety profile.
