Hoodia Gordonii is a water retaining plant, also known as a succulent, which grows without leafs. Being native to the south of Africa, it has been in use for an indeterminable amount of time as an appetite suppressant. It is very easily identifiable, because the flowers of this plant have a rotten meat odor. The ingredient of the plant which is responsible for the appetite suppressing effects has been named P57. It is a steroidal glycoside which seems to act directly to the central nervous system’s mechanisms and supposedly raises the content of adenosine triphosphate in brain by at least a half. The effects of P57 in trials were registered as capable to reduce food intake by some fifty per cent on a daily basis.
