Due to the tradition of food use of Hoodia plants, certain species were included in a scientific research project established by the South African statutory council known as CSIR (Council for Scientific and Industrial Research) to screen a large number of bush foods. As part of the screening process, extracts of plants were made and tested for toxic effects. Surprisingly, it was observed that the Hoodia extracts caused a decrease in appetite and body weight in animals that did not appear to be due to a direct toxic effect of the extract.
