The properties of Round Leaf Buchu
Agathosma Betulina is a flowering plant in the family Rutaceae, native to the lower elevation mountains of western South Africa, where it occurs near streams in fynbos habitats.
It is known by the common name round leaf buchu. The very similar plant Agathosma Crenulata is known as the oval leaf buchu, and has been used for the same purposes.
The essential oils and extracts of the leaves are used as flavoring for teas, candy, and a liquor known as buchu brandy in South Africa. The two primary chemical constituents of the oils of A. betulina are isomenthone and diosphenol. The extract is said to taste like blackcurrant.
The plant has been used by the indigenous people of South Africa to as a folk remedy for various disorders. Dutch settlers in early times used Agathosma betulina commonly called buchu to make a brandy tincture.
