Buchu
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).
How It Works
The leaves of buchu contain 1.0–3.5% volatile oils as well as flavonoids.1 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.2
