Buchu (Agathosma betulina) leaves and oil of buchu were used by the indigenous people of the Cape area of South Africa for hundreds of years. Although its original use is unclear, it appears to have been applied topically on the skin, possibly as an insect repellant, and also used internally for stomach problems, rheumatism, and bladder problems. Buchu's original genus was Barosma, which was changed to Agathosma.

Buchu contains both diosmin and hesperidin, which indicates it may have anti-inflammatory, hypolipidemic (blood cholesterol lowering), and vasoprotective actions.

Most of the plants are still grown in South Africa where the government exercises strict control over the gathering of the leaves to prevent destruction of wild plants.
