- | " | + | 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. \\ |

+ | The dried or fresh leaves of buchu are used as diuretic, diaphoretic and stimulant tonic. "Buchu is widely used and has a great reputation for treaing kidney and urinary tract diseases, for the symptomatic relief of rheumatism, ans also for ecternal application on wounds and bruises (in folk medicine as buchu vinegar). Buchu is an excellent tonic and is used to treat minor digestive disturbances. Buchu leaf and oil are important flavour components in herbal teas and food products." | ||
