Ephedra is an herb. Usually branches are used to make medicine, but the root or whole plant can be used. Ephedra contains a chemical called ephedrine. Ephedrine stimulates the heart, the lungs, and the nervous system. What is it used for?
There is limited evidence that ephedra may decrease the symptoms of asthma, bronchitis, and other breathing problems but in most cases the dose needed to lessen these symptoms is extremely high, and considered by many experts to be unsafe, and not worth the risk, given the many safer alternative treatments. At this time there is no clear evidence that ephedra causes weight loss or improved athletic performance. Safety Concerns
There is some evidence that ephedra is not safe when used in high doses or when used long-term. It has been linked to many reported cases of high blood pressure, heart attack, seizures, strokes, loss of consciousness, and even death. Ephedra may cause dizziness, restlessness, anxiety, irritability, loss of appetite, nausea, and vomiting in some people. Taking ephedra with other stimulants, such as caffeine, is considered dangerous and may increase the risk of serious side effects. It is recommended you do not use ephedra if:
