The hoodia information that is currently available comes mostly from a British pharmaceutical company called Phytopharm, but they do not like for their findings to be applied to natural hoodia gordonii products that are currently on the market. They say that the hoodia studies that they have completed at this time show that hoodia gordonii is safe and is effective as an appetite suppressant, but they say that the hoodia gordonii products that are currently on the market may not be genuine hoodia gordonii. They also say that the active molecules may not be present in sufficient amounts to cause the desired effect. Perhaps they would have been happier if they could have kept all hoodia information
