Caralluma Fimbriata- This herb is claimed to be used over centuries in India to suppress appetite and hence considered to be the best for those whose occupation is hunting. Caralluma Fimbriata resembles a cactus plant and is considered to be a member of the cactus family, yet it’s extremely succulent. It’s great for those who want to loose weight and also lower their blood sugar. For ages, it has been included in the diet of Indians and they either use it as a cooked vegetable or even mix it in their pickle. There are some who also eat it raw. By blocking the activity of various enzymes, it helps blocking the formation of fat hence, the fat reserves are burned. There are no side effects by the use of Caralluma Fimbriata as proven by Ayurvedic studies.

Grape seed is the seeds of the ordinary grapes. They are used primarily because they have polyphenols recognized as anti oxidants. Research confirms numerous health benefits of grape seed extracts; they limit lipid oxidation, thus controlling high blood pressure and high cholesterol levels. Grape seeds contain phenolics, which are useful in treatment of heart disease because they inhibit platelet aggregation and reduce inflammation, however, the results are preliminary and more research is being done to confirm these facts. A polyphenol contained in grape seeds is resveratrol which may inhibit cancer cell growth and proliferation, and it may also be active against HIV by inhibiting expression and replication of the genome of the virus.

Hoodia Gordonii, which although popular, has 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 (The Active ingredient in Raw, Fresh Cut Hoodia, not dried) 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 an animal study and INJECTIONS IN THE BRAIN are very different from oral consumption, so it cannot be used to show that oral hoodia can suppress appetite in humans. Hoodia Gordonii is a succulent (a cactus of the aloe family) found in the Kalahari desert of South Africa. Most Hoodia Gordonii products contain very little, if any of the active ingredient needed to suppress hunger. Real Hoodia is very rare and is even an endangered plant. Most importantly, Hoodia has only demonstrated any effect in fresh, raw pieces of the plant. The effectiveness of powdered Hoodia has yet to be shown and may actually increase hunger. It's main use is as a cheap alternative to the more expensive weight loss herbs, which are the only alternative left after the banning of ephedra. Most supplement manufacturers can not use the more expensive weight loss herbs because it will result in a product that would be too expensive to compete with other more popular inexpensive diet supplements.
