Hoodia is a bitter-tasting cactus-like plant. Hoodia is a Succulent botanical which resembles a "cactus". For this reason, hoodia is often mistaken called the "African hoodia cactus". In the last few years, hoodia has been heavily marketed for weight loss and has become immensely popular. Hoodia Gordonii grows in clumps of green upright stems. Although it is often called a cactus because it resembles one, hoodia is actually a succulent plant. It takes about five years before hoodia gordonii's pale purple flowers appear and the plant can be harvested. There are over 13 types of hoodia. The only active ingredient identified so far is a steroidal glycoside that has been called "p57". Currently, only hoodia gordonii is thought to contain p57.

Despite its popularity, there are no published randomized controlled trials in humans to show hoodia is safe or effective in pill form. One study published in the September 2004 issue of Brain Research found that injections of p57 into the appetite center of rat brains resulted in altered levels of ATP, an energy molecule that may affect hunger. The animals receiving the P57 injections also ate less than rats that received placebo injections. However, this was and animal study and injections in the brain are different from oral consumption, so it cannot be used to show that oral hoodia can suppress appetite in humans. The manufacturer Phytopharm cites a clinical trial involving 18 human volunteers that found hoodia consumption reduced food intake by about 1000 calories per day compared to a placebo group. Although intriguing, the study wasn't published or subjected to a peer-review process, so the quality of the study cannot be evaluated.

People have different views when there is a debate on Hoodia products.
Hence it is very important to take a look at some of the common guidelines to nullify the chances of buying fake products and maximize the chances of getting a real Hoodia product.
To select a good Hoodia product you must know the following facts about Hoodia:
