Buchu is a plant native to South Africa, known scientifically as Agathosma betulina or Barosma betulina, belonging to the Rutaceae family. The plant features small, rounded leaves and bears five-petaled flowers, typically white or pale pink. Buchu leaves are the primary source of its distinct scent and are traditionally used for their medicinal properties.
The scent profile of buchu is uniquely pungent and minty with pronounced peppery and eucalyptus-like undertones. Some also detect hints of blackcurrant, due to the presence of a chemical compound similar to that found in the fruit. This complex aroma makes buchu particularly valued in the fragrance industry, where it's used to add depth and freshness to perfumes and scented products. Additionally, buchu oil, extracted from the leaves, is employed in various culinary and medicinal applications, capitalizing on both its aromatic and therapeutic qualities.
