Bearberry Leaves
Bearberry leaves contain arbutin, which converts to hydroquinone in alkaline urine to provide antimicrobial effects against urinary tract infections. The herb also acts as a natural diuretic, increasing urine flow to help flush bacteria and toxins from the urinary system.

Origin & History
Sourced from the leaves of Arctostaphylos uva-ursi, native to North America, Europe, and Asia Bearberry Leaves has been cultivated and wild-harvested across temperate and tropical regions for centuries. Herbalists and traditional practitioners have relied on this plant in preparations ranging from teas to tinctures, recognizing its unique phytochemical profile and broad-spectrum wellness applications.
Historical & Cultural Context
Bearberry Leaves carries a meaningful place in traditional wellness systems. Originating from Sourced from the leaves of Arctostaphylos uva-ursi, native to North America, Europe, and Asia. Historically prized for its capacity to support urinary tract health by acting as a natural diuretic and antimicrobial, reducing inflammation and infections such as utis.
Health Benefits
Supports urinary tract health by acting as a natural diuretic and antimicrobial, reducing inflammation and infections such as UTIs. Promotes detoxification by flushing out toxins through increased urine flow. Provides antioxidant benefits, protecting cells from oxidative stress and reducing inflammation. May assist in managing kidney and bladder health by reducing irritation and promoting tissue repair.
How It Works
Bearberry's primary bioactive compound arbutin is hydrolyzed by β-glucosidase in the kidneys to release hydroquinone, which exhibits antimicrobial activity in alkaline urine (pH >7). Hydroquinone disrupts bacterial cell walls and inhibits bacterial growth, particularly against E. coli and other gram-negative bacteria. The herb's diuretic action increases urine production through enhanced kidney filtration, helping flush pathogens from the urinary tract.
Scientific Research
Bearberry leaves have been used for centuries in Native American and traditional European medicine to support urinary health and treat bladder infections. Their medicinal value lies in their unique composition of arbutin and tannins.
Clinical Summary
Small clinical studies have demonstrated bearberry's efficacy for recurrent UTI prevention, with one study of 57 women showing 23% recurrence rate compared to 100% in placebo group over 12 months. Research typically uses standardized extracts containing 400-840mg arbutin daily for 7-14 days. Most evidence comes from traditional use and in vitro studies, with limited large-scale randomized controlled trials. Safety data is primarily based on short-term use studies lasting 2 weeks or less.

Safety & Interactions
Bearberry is generally safe for short-term use (up to 2 weeks) but prolonged use may cause liver toxicity due to hydroquinone content. High doses can cause nausea, vomiting, and green-colored urine. The herb may interact with lithium by reducing its excretion, potentially increasing lithium levels. Pregnant and breastfeeding women should avoid bearberry due to insufficient safety data and potential uterine stimulant effects.
