Ephedrine is an evergreen shrub-like plant native to Central Asia and Mongolia. The principal active ingredient, ephedrine, is a compound that can powerfully stimulate the nervous system and heart. Ephedra has been used for more than 5,000 years in China and India to treat conditions such as colds, fever, flu, headaches, asthma, wheezing, and nasal congestion. More recently, ephedra was used as an ingredient in dietary supplements for weight loss, increased energy, and enhanced athletic performance. Ephedrine is an alkaloid chemical compound traditionally obtained from the plant Ephedra Sinica, (otherwise known in the Chinese language as Ma Huang). It is a plant based substance used in traditional Chinese medicine for over 5,000 years, often used in the treatment of various respiratory, cold and hay fever related conditions. In more recent times, Ephedra has also been used extensively around the world as a performance-enhancing substance, which is now prohibited in most competitive sports events, as well as for a non-prescription weight loss supplement. Ephedrine is known for its thermogenic (fat burning) properties and subsequent positive metabolic increase. In addition, various derivatives of Ephedra have since been synthesized to treat low blood pressure. The ephedrine stacker, also known as the ECA Stack (ephedra, caffeine, aspirin), was the most popular ephedra supplement used within the sports and bodybuilding community. When Ephedrine and caffeine are stacked together it causes a ramp up of a user’s metabolism and creates a thermogenic environment (the ultimate fat burning environment). This puts your body in a state to absolutely demolish fat mass and retain muscle mass. .
