Buchu (Agathosma betulina or Agathosma crenulata) is traditionally used in South African herbal medicine for urinary tract and bladder issues, including symptoms that might be described as “irritable bladder.” The Khoisan people and later colonial settlers employed buchu leaves as a diuretic and urinary antiseptic. In the 19th and early 20th centuries, it gained popularity in European and American herbal medicine as a remedy for cystitis, urethritis, and other lower urinary tract complaints. The essential oils and flavonoids in buchu are thought to provide mild antiseptic and anti-inflammatory effects, with some laboratory studies suggesting antimicrobial and diuretic activities.

However, despite this strong historical use, modern scientific validation is limited. There are few high-quality clinical trials evaluating buchu's effects on bladder irritation or related conditions in humans. Most contemporary use and inclusion in herbal blends for urinary health are based on tradition and anecdotal reports rather than robust scientific evidence. Safety profiles are generally favorable when used in traditional dosages, but concentrated extracts or essential oils may have adverse effects. In summary, the use of buchu for irritable bladder is primarily justified by tradition, with a low but existing level of supporting evidence (rated 2/5), mostly from historical use and some basic pharmacological studies rather than clinical trials.
