Ephedrine

Ephedrine, when taken throughout the day, significantly boosts metabolism and reduce feeling of hunger. For this reason, ephedrine is often used in weight loss therapy in overweight patients. Ephedrine is also used in the flu therapy, since it dilates the bronchioles and stimulates central nervous system. Derived from the leaves and stem of the Ephedra Sinica (which grows in China), Ephedrine is a biologically active natural product.
