Hoodia is a stimulant-free weight-loss aid / or pill. Everything I've read says it's an all-natural, plant-based supplement. The full name "Hoodia Gordonii" is a plant found in the Kalahari Desert of South Africa. The story goes, it has been used by native tribes for centuries to help limit hunger while going out on those long hunting expeditions.

Other literature says it's a supplement that works by tricking your brain into thinking you've already eaten; thus feeling full.

A molecule called P57 is found in Hoodia and is tagged as the reason it can help with appetite suppression.
