Rating (out of 5): 1

Rubus ursinus, commonly known as the Pacific blackberry, has a history of traditional use among Indigenous peoples of North America for various ailments, including urinary tract issues. Ethnobotanical records indicate that the leaves and roots were occasionally used in teas or infusions to address urinary discomfort and other mild infections, likely due to the plant's astringent properties imparted by tannins. However, there is very little direct documentation or clinical evidence linking Rubus ursinus specifically to the effective treatment or prevention of urinary tract infections (UTIs). Most traditional uses of Rubus species for urinary issues are based on generalized reports of their astringency, which could theoretically help reduce inflammation or irritation of mucosal tissues.

Scientific studies examining the efficacy of Rubus ursinus for UTIs are lacking. The plant does contain polyphenols and tannins known for antimicrobial and anti-inflammatory activity, but there is no direct research connecting these constituents in Rubus ursinus to the inhibition of the pathogens responsible for UTIs (such as Escherichia coli). As such, while traditional use exists, it is not strongly substantiated by either robust ethnobotanical records or scientific studies, resulting in a low evidence rating for this application.
