What the evidence says about Uva ursi

Long traditional use with limited modern trial support. The EMA found no clinical efficacy trials and granted traditional-use registration only, and the ATAFUTI randomised trial in 382 UK women found no difference from placebo. Herbal references consistently describe it as a SHORT-TERM herb, which sits oddly inside products designed for daily indefinite use.

The grade "traditional" means: traditional — A long history of use but little or no human trial evidence for this outcome. Grades are explained in full on our methodology page.
