Parts Used & Where Grown
Buchu is a low shrub native to the Cape region of South Africa. The dried leaves are harvested during the flowering season. The oil can be obtained by steam distillation of the leaves. The two primary species of buchu used commercially are Agathosma betulina (syn. Barosma betulina) and Agathosma crenulata (syn. Barosma crenultata).
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

Urinary Tract Infection
Refer to label instructions
Buchu leaf preparations have been historically used as a urinary tract disinfectant and diuretic.
Buchu leaf preparations have a history of use in traditional herbal medicine as a urinary tract disinfectant and diuretic.4 However, the German Commission E monograph on buchu concludes that insufficient evidence supports the modern use of buchu for the treatment of UTIs or inflammation.5
Traditional Use (May Not Be Supported by Scientific Studies)
Buchu leaf preparations have a long history of use in traditional herbal medicine as a urinary tract disinfectant and diuretic.1 Buchu was used by herbalists to treat urinary tract infections and inflammation, as well as inflammation of the prostate. In Europe, it was also used to treat gout.2 The original use of buchu by the native peoples of southern Africa is unclear because buchu is a general term for aromatic plants.3 It appears to have been applied topically, possibly as an insect repellant, and also used internally for stomach problems, rheumatism and bladder problems.
How It Works
How It Works
The leaves of buchu contain 1.0–3.5% volatile oils as well as flavonoids.6 The urinary tract antiseptic actions of buchu are thought to be due to the volatile oils. The primary volatile oil component thought to have antibacterial action is the monoterpene disophenol. However, one test tube study using buchu oil found no significant antibacterial effect.7
How to Use It
The German Commission E Monograph concludes there is insufficient evidence to support the modern use of buchu for the treatment of urinary tract infections or inflammation.8 However, some traditional herbal practitioners continue to recommend the herb for these conditions. Traditional recommendations for the herb include the use of 1–2 grams of the dried leaf taken three times daily in capsules or in a tea.9 Tinctures can be used at 2–4 ml three times per day.
