Berberine is a plant-derived alkaloid found in herbs such as Berberis vulgaris (barberry) and Coptis chinensis (goldthread), and has a long history of use in traditional medicine for treating infections, including those affecting the urinary tract. Modern scientific evidence suggests that berberine exhibits significant antimicrobial activity against a range of pathogens, including Escherichia coli (E. coli), the most common causative agent of bladder infections (urinary tract infections, or UTIs). In vitro (laboratory) studies have demonstrated that berberine can inhibit the growth and adhesion of uropathogenic bacteria to the bladder wall, potentially reducing infection risk and severity. Some animal studies also indicate that berberine administration can reduce bacterial load and inflammation in the urinary tract.

However, while these findings are promising, clinical evidence in humans is limited. There are a few small clinical trials and case reports suggesting beneficial effects, but large-scale, high-quality randomized controlled trials are lacking. Therefore, while scientific rationale exists, and laboratory/animal data are supportive, current human clinical evidence is not robust enough to strongly recommend berberine as a primary therapy for bladder infections. It may be considered as an adjunct to conventional treatments, but patients should consult healthcare providers before use, especially as berberine can interact with various medications and is not recommended during pregnancy or for certain populations.
