Buchu Leaf Oil
A versatile flavour & fragrance enhancer.
Buchu (Agathosma betulina and crenulata)
Buchu (Agathosma betulina and Agathosma crenulata. Rutaceae) is one of the best-known South African herbs both locally and internationally. The indigenous people first introduced buchu as a medicinal plant to the European settlers at the Cape. The use of the plant subsequently spread to Europe and America where it was initially used as an antiseptic and diuretic.
Buchu betulina (A. betulina) is a fragrant shrub with round leaves (round-leaf buchu) which seldom exceeds a height of 1 metre. The flowers are star like, and white or mauve in colour.
Buchu crenulata (A. crenulata) is an aromatic woody shrub with larger, elongated leaves (long-leaf buchu) which reaches a height of up to 2 metres. The flowers are white or mauve in colour.
Although the essential oil of the two species basically contains similar chemical compounds, the concentration of individual compounds varies considerably.
Buchu is endemic to the mountains of the Western Cape Province, South Africa, ranging from Clanwilliam in the north, to Worcester/Somerset West in the south.
By steam distillation of stems and leaves the oil is produced from cultivated plantations.
