 "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 [[http://www.thegoodscentscompany.com/data/rw1003111.html|isomenthone]] and diosphenol. The extract is said to taste like blackcurrant." \\

+P-menthane-8-thiol-3-one was identified as a specific odor-determining ingredient of buchu leaf oil. \\

 GC and GC-O analysis of 16 black currant juice samples showed that several commercially available products contained Buchu oil to improve aroma, without any such indication on the label. Buchu oil is used because its constituent 8‐mercapto‐p‐menthan‐3‐one has a catty odour that is similar to the catty odour of black currants. As retention times of the two odours are different, sniffing the effluents of the gas chromatographic column is a way to detect the addition of Buchu oil. \\
