==The benefits of Ephedra are==
*Ephedra sinica is an herb with a long history of use in traditional Chinese medicine for asthma, bronchitis, allergies and cold and flu symptoms.*During the 80s, ephedra became popular outside of traditional Chinese medicine for weight loss and to enhance sports performance. Its popularity continued to grow, and it was found in many nutritional supplements marketed for weight loss and performance enhancement until supplements containing ephedra were banned by the U.S. Food and Drug Administration (FDA) in 2006.*Weight Loss :Ephedra appears to cause weight loss when combined with caffeine. It's thought to work by increasing energy expenditure, increasing basal metabolic rate and suppressing appetite. Whether ephedra alone works is less clear.Prior to the ban on ephedra supplements, many dietary supplements marketed for weight loss also contained caffeine-containing herbs, such as green tea, yerba mate and guarana. The ephedra/caffeine combination, however, is now widely believed to heighten the potential health risks and is not recommended.*Sports Performance : Ephedra is similar in structure to amphetamine, so it has been used to increase athletic performance in strength and endurance sports, increase alertness and aggressiveness on the field, and reduce fatigue in sports such as ice hockey, baseball, football and cycling. There isn't good evidence, however, that it can improve sports performance, and is not recommended for this purpose given the potential side effects. Ephedra is banned by many sports associations, including the International Olympic Committee, the National Football League (NFL) and the National Collegiate Athletic Association (NCAA).* [[Vasoconstrictor]] : Herbs Causing Constriction Of Capillaries*The primary active ingredients in ephedra are believed to be the alkaloids ephedrine and pseudoephedrine, which are thought to increase heart rate, constrict blood vessels (which increases blood pressure), dilate bronchial tubes (which makes it easier to breathe) and have thermogenic properties (increases body heat and metabolic rate).*Asthma and Other Respiratory Disorders : Ephedra has a long history of use in traditional Chinese medicine as a folk remedy for asthma, bronchitis, allergies, fever, chills and cold and flu symptoms, such as nasal congestion. The ephedrine and pseudoephedrine in ephedra widen bronchioles, which are the small airways in the lungs. Although ephedrine was used for asthma, medications with fewer potential side effects are now more commonly recommended.

A synthetic form of pseudoephedrine is found in over-the-counter decongestants and cold medicines, and synthetic ephedrine is used to treat asthma (but it has largely been replaced by newer medications). Synthetic ephedrine and pseudoephedrine have also been used to make the illicit street drug methamphetamine, as reported by The New York Times.
