Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Buchu (Agathosma betulina and related species) has a long history of traditional use in South African herbal medicine, particularly to support urinary tract health and the bladder. Indigenous Khoisan and later European settlers used buchu as a diuretic and for urinary tract disorders such as infections, inflammation, and kidney issues. The leaves were commonly brewed into teas or tinctures for these purposes. In the late 19th and early 20th centuries, buchu became popular in Western herbal medicine, often included in remedies for cystitis, urethritis, and general bladder health. However, scientific studies on buchu’s effectiveness are limited. Some in vitro and animal studies suggest mild antimicrobial and anti-inflammatory properties, but robust clinical trials in humans are lacking. The main active components, such as diosphenol and various flavonoids, may contribute to its traditional uses, but direct evidence for bladder support remains weak. Overall, while buchu’s use for the bladder is well-established in traditional herbalism, scientific validation is insufficient, justifying a moderate evidence rating based mainly on historical precedent rather than rigorous research.
