The first scientist to perform clinical trials on Hoodia was Dr. Richard Dickens. He was the first to explain the actual work of Hoodia. Whenever a person takes a meal the blood sugar level is raised and nerve cells that are present in the brain and able to sense them actually come into the contact and tell you that you are full. The effect of Hoodia is explained by the powerful molecule which is more powerful that glucose actually (sugar). The nerve cells which get affected by Hoodia respond in feeling that tells you have got a heavy meal and not ready to continue eating anymore.

You don't eat roots and flowers of Hoodia right after they have been picked up. Natives usually cut it to open the skin and allow the flesh and the sap of the plant outside. Due to the bitter taste it is not taken right after being picked. The most comfortable way is to dry the plant and when it is dried turn it into the powder form. The powder than can be easily taken with any food and successfully lower the appetite of yours.
