Belonging to a flowering plant family, Apocynaceae, Hoodia is one of the 13 species in the family. Often it is mistaken for a cactus because it looks like a cactus but actually it is a stem succulent. It reaches to a meter in height and has large flowers. Its flower has a tan color and has strong smell. They are naturally found in the Namib Desert of Africa spread across the Central Namibia to the southern Angola. Hoodia gordonii, one of the 13 species of Hoodia has been investigated for its use by local inhabitants as an appetite suppressant. Since then Hoodia has been marketed extensively as a weight loss product across the world. The originators of this knowledge are the San Bushmen of the Kalahari Desert. The plant is harvested after it begins to flower which takes five years. The San Bushmen have been using the plant for centuries for various purposes such as indigestion and for the treatment of small infections besides being taken for long hunting trips as an appetite suppressant.
