Hoodia Gordonii is a small cactus, originating from the Kalahari Desert. Its main purpose is its amazing ability to suppress appetite. Even though it seems to be an unusual choice for many as a weight loss aid, it has been reported that Hoodia can successfully suppress appetite for up to 24 hours!
Used by the Sans Bushman tribe for centuries, the Hoodia Gordonii plant allowed the tribe hunters to go without food or water for an extended period of time. This allowed them to concentrate and hunt for days uninterrupted and without feeling hungry. Even to this day, Hoodia Gordonii is used to encourage appetite loss as part of their tradition.
