Agathosma
（重定向自Buchu）
Agathosma is a genus of about 140 species of flowering plants in the family Rutaceae, native to the southern part of Africa. Common names include Buchu, Boegoe, Bucco, Bookoo and Diosma. Buchu formally denotes two herbal species, prized for their fragrance and medicinal use. In colloquial use however, the term (see Boegoe) is applied to a wider set of fragrant shrubs or substitutes.
