„Agathosma crenulata and A. betulina are commercially grown for their (essential) oil.“
http://www.plantzafrica.com/plantab/agathoscren.htm

„Essential oil content: not less than 1.5% (range: 1.32-2.19-4.0%)… the essential oil, of which the major constituents are limonene (9.0-18%), menthone/isomenthone (6.49-28.0%), pulegone/isopulegone (51.4-60.0%) and both cis- and trans-8-acetylthio-p-menthane-3-one (7.03%). Neither diosphenol/ψ-diosphenol (“buchu camphor”) nor the 8-mercapto-p-menthane-3-ones,characteristic of A. betulina , have been detected in the oil of this species. “
[cit. given: http://www.plantzafrica.com/medmonographs/agathosmacrenulata.pdf ]

„Oil from oval leaf buchu is less desireable because it contains little or no diosphenol and hig levels of pulegone, a potentially toxic compound.“
[Medicinal Plants of the World. Ben-Erik Van Wyk and Michael Wink, Pretoria 2004, 35]

Used as flavoring agent and as herbal remedy for digestive disturbances and urinary tract infection.
