 How was the Hoodia cactus secret discovered?
In 1996 the Council for Scientific and Industrial Research (CSIR) in South Africa was doing a study of indigenous foods that the Bushmen ate. Part of the study was to test for toxic effects of any plants that were consumed by the Bushmen. When they came to Hoodia Gordonii, not only was it non-toxic - it helped animals lose weight!
They found when they fed hoodia to animals, the animals lost weight. By 1997, the CSIR isolated the bioactive compound in Hoodia responsible for appetite suppression and obtained a patent. The patent was licensed to Phytopharm and they named the molecule - P57 (because it was the 57th product they spent money on).
