Hoodia are substances derived from Hoodia Gordonii, also commonly referred to as P57, is a cactus-like plant that grows in the deserts of Africa. An anthropology report of the San Bushmen of the Kalahari desert detailed their uses of Hoodia Gordonii to ward off hunger and thirst during long hunting trips in the desert. This report was shown on the BBC network and then later on the TV news program 60 Minutes.

At the time a pharmecutical company called Phytopharm held the patent license to hoodia gordonii. Phytopharm and the South African Council for Scientific and Industrial Research, have spent over $20 million researching Hoodia Gordonii. They found that one steroidal glycoside was responsible for its weight-reducing properties. They named this glycoside P57.

Later the pharmecutical company Pfizer applied for a sub-license to sell hoodia as well. The sub license was granted and now many companies are selling various forms of Hoodia Gordonii and P57. Due to the great increse in demand, Hoodia Gordonii is now on the protected plant species list and a license must be obtained to export it from Africa.

Hoodia works by fooling the brain into believing the blood sugar levels are higher than they real are thus suppressing the desire to eat. Hoodia limits your appetite so you are not as hungry all the time. And people are seeing wonderful results from this product.
