Buchu powder comes from the dried, ground leaves of two South African shrubs, *Agathosma betulina* or *Agathosma crenulata*. The Khoisan and other native peoples introduced its traditional uses.
People take the powder as tea or in capsules to ease urinary tract discomfort and support gentle digestion. A mild, aromatic taste makes it a common addition to herbal blends.
Buchu contains compounds that can increase urine output. Anyone using diuretic medications or managing kidney issues should exercise caution. Pregnant and nursing women need to avoid it because safety information is unavailable.
