What does buchu mean?
Buchu is the common name for a group of aromatic shrubs belonging to the genus Agathosma, native to the mountains of the Western Cape in South Africa. The best-known species, Agathosma betulina, produces small, oil-rich leaves with a pungent scent often described as reminiscent of blackcurrant or mint. For centuries the indigenous Khoisan peoples used buchu leaves medicinally, and European settlers adopted the plant as a remedy, valuing it as a mild diuretic and urinary antiseptic. Today the dried leaves, sold simply as "buchu," remain an ingredient in traditional herbal preparations, while the essential oil is prized by flavour houses for lending a distinctive fruity note to liqueurs, brandies, and craft gins. Because wild stocks are limited, buchu is now cultivated commercially under strict regulation, making it both an economically significant and botanically distinctive South African export.

This unassuming South African shrub gives some gins a surprising blackcurrant aroma — thanks to a compound it shares with cassis.

Etymology of buchu
The word buchu entered English in the late eighteenth century, borrowed from the Khoekhoe (Hottentot) languages of southern Africa, in which it was the native name for the aromatic plant. It was initially applied in colonial botanical and medical writing to describe the shrub and its medicinal leaves, and the name spread into Dutch Afrikaans usage alongside English. As a loan from Khoekhoe, it has no Indo-European cognates, so it stands outside the Latin- and Greek-derived families that supply most English botanical vocabulary.
