Rating (out of 5): 2

Buchu (Agathosma betulina and related species) is a plant native to South Africa, traditionally used by indigenous peoples and later by European settlers as a remedy for urinary tract ailments, including urinary tract infections (UTIs). Its leaves have been made into infusions or tinctures believed to act as diuretics and urinary antiseptics. This traditional use has persisted into modern herbal medicine, with buchu often marketed as a urinary tract "support" ingredient in supplements and herbal blends.

However, scientific validation for buchu's effectiveness in treating or preventing UTIs is limited. Laboratory studies have shown that certain compounds in buchu, such as diosphenol, possess mild antimicrobial and diuretic properties. Yet, there is a lack of well-designed human clinical trials demonstrating its efficacy or safety for UTIs. Most evidence supporting its use is anecdotal or derived from historical records rather than rigorous modern research. Major medical organizations and review articles generally do not recommend buchu as a primary or evidence-based treatment for UTIs.

In summary, while buchu's use for urinary tract health has a strong basis in traditional medicine, it lacks robust scientific support. The evidence rating reflects the presence of some in vitro studies and a long history of use, but the absence of high-quality clinical data.
