Dr. Richard Dickens was the first one to perform clinical trials on Hoodia and explained how it actually works.
The hypothalamus is an important part of our brain. Inside hypothalamus, nerve cells are present sensing glucose sugar. When a meal is taken, the blood sugar rises and these cells become active and one feels that they are full.

Hoodia consists of a molecule which is much more powerful and active than glucose. With the effect of Hoodia, nerve cells become active and you feel as if you had a heavy meal and do not feel like eating any more.

Skin, roots and flowers are not eaten by people readily. To use it in a natural manner, cut open its skin to eat the sap and flesh of plant. The plant, Hoodia is famous for its bitterness that cannot be taken in its fresh form by people. In South Africa, Hoodia plant is first dried and than converted into powdered form. This powder can be taken along with the regular food and it suppresses the appetite in return.
