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.

In most cases the use of synephrine is paired with a diet and body building plan, where weight loss and muscle building is essential.

Garcinia Cambogia is a small fruit that looks just like a small size pumpkin. An extract from its fruit and rind has been used to prepare various products mainly for weight loss. This herb, which is mainly found in India and some parts of Asia, is believed to suppress appetite and enhance fat-burning due to the presence of hydroxycitric acid (HCA) in the extract. This is how it works - HCA inhibits an enzyme called citrate lyase that plays an important part in converting excess carbohydrates into fat, but when it is inhibited, the body burns the extra carbs. While animal studies have suggested reduced food intake and decrease in body fat, human trials have not been so conclusive.
