Citrus Aurantium is the Latin name for a citrus tree which grows bitter oranges. Traditionally being used by Chinese medicine and herbologists, the extract of the orange and the peel was used as a dietary supplement in concoctions with other herbs to suppress appetite. While other active ingredients of the citrus aurantium may contribute and even promote the effect, the main ingredient used in all weight loss products is synephrine, an alkaloid similar to ephedrine. It is a phenethylamine; it influences the alpha1 adrenergic receptor, constricting blood vessels, additionally increasing the heart rate and the blood pressure. In most cases the use of synephrine is paired with a diet and body building plan, where weight loss and muscle building is essential.

Corida Salicifolia- Cha De Bugre, or Cordia salicifolia, is a plant native to South America and is found predominantly in Brazil, Paraguay and Argentina. Cordia Salicifolia Extract has been traditionally used there as a weight loss aid and generally as a stimulant drug. While the use of Cordia Salicifolia Extract is slowly gaining widespread interest, there have been limited studies done, which have indicated it as a stimulant, antioxidant, diuretic and a heart tonic. In Japan, a study has shown that Cordia Salicifolia Extract has strong inhibiting properties on the Herpes virus. Cordia ecalyculata, which is a synonym for Cordia salicifolia, is currently being marketed as a potent appetite suppressant, with missing research data equaling to a safe to use presumption. However, the heart tonic properties sound encouraging.

Green Tea Extract, a bioflavonoid rich, potent extract used primarily for fighting free radicals. It contains a high content of polyphenols, which are a class of bioflavonoids. Green tea extract contains a potent antioxidant, EGCG, which is over 200 times more powerful than vitamin E in neutralizing the pro-oxidants and free radicals that attack lipids in the brain. Green tea extract helps with thermogenesis and aids in the metabolism of fat. Green Tea has been used for years as a powerful antioxidant, it may also be helpful in shedding fat. The most obvious benefit to dieters is that it works without increasing the heart rate most often found in diet aids. The increased heart rate leaves dieters jittery and eventually, most dieters stop using the supplement and gain weight back. Now through using green tea extract, dieters get the weight loss benefits without any of the jittery effects, especially in obese individuals with hypertension and other cardiovascular complications.
