Phytoparm which is a pharmaceutical company owns the patent to P57 which is the steroidal glycoside within Hoodia that causes its appetite suppressing effect. In 1997 Pharmaceutical giant Pfizer entered a deal with Phytoparm and tried to isolate P%7 into a form that could be marketed to the public. Within several years of research, they determined that this was not possible, and they pulled out of the agreement.

For years Hoodia was sold online by various companies and individuals. They were selling dried, powered Hooodia. However, the appetite suppressing ability of hoodia gordonii is only found in large fresh pieces of the plant The amount of P57 in the powder was such a small amount that it could not produce the desired effect. The products present were not regulated or inspected and were defnityl not a pure Hoodia diet pill.

It wasn’t until December 15 2004 that Phytopharm found a way to extract P57 and successfully put the right amount into pill form to be sold the public.
