Rating (out of 5): 2

Bearberry (Arctostaphylos uva-ursi) has a long history of traditional use for urinary tract and bladder issues, including symptoms resembling an irritable bladder. Traditional herbal medicine, especially in Europe and North America, has used bearberry leaves as a remedy for mild urinary tract discomfort, cystitis, and irritable bladder symptoms. The key compound, arbutin, is metabolized to hydroquinone, which is believed to exert mild antimicrobial effects in the urinary tract. Historically, bearberry was included in pharmacopeias and herbal compendia for these purposes, often as a tea or extract.

However, scientific evidence supporting bearberry’s efficacy specifically for irritable bladder (overactive or painful bladder syndrome) is limited. Most modern studies focus on bearberry’s role in uncomplicated urinary tract infections (UTIs) rather than irritable bladder, and results are mixed. A few small clinical trials and laboratory studies indicate antimicrobial and anti-inflammatory properties, but significant, high-quality clinical research is lacking for irritable bladder specifically. Safety concerns also exist, especially with prolonged use due to potential toxicity from hydroquinone metabolites.

In summary, bearberry’s use for irritable bladder is rooted primarily in traditional herbal medicine, with only modest scientific evidence for related urinary tract conditions. People considering bearberry should consult healthcare professionals, especially because of potential side effects and interactions with other medications.
