Ephedra

Ephedra was a popular weight loss pill, until it was banned in the United States due to safety concerns. This naturally occurring substance is chemically similar to amphetamines and may suppress the appetite and increase metabolism. Although ephedra may be effective for short-term weight loss, potentially dangerous side effects are possible. Some of these side effects may include heart attacks, strokes, or seizures.

What Is Ephedra?

Ephedra (also known as ma huang) is a naturally occurring substance that is used in traditional Chinese medicine. It was popular as a weight loss supplement, until it was banned in the United States due to safety concerns.

How Does It Work?

The active ingredient of ephedra is a chemical known as ephedrine (as well as several other similar chemicals). These ingredients are chemically similar to amphetamines and act as powerful stimulants. While these chemicals may suppress the appetite or increase metabolism (both of which can help with weight loss), they are also responsible for many of the pill's dangerous side effects.
 

Is It Effective?

There is some scientific evidence to suggest that ephedra may be effective for short-term weight loss. Unfortunately, while it may be effective, it is also potentially dangerous.

Is Ephedra Still Available?

Ephedra has been banned in the United States, and the ban is still in place, despite what you may read on the Internet. Even though ephedra is banned, you may be able to buy it over the Internet from foreign countries or from local companies that are illegally selling it. Unfortunately, it seems that some people are still desperate enough to lose weight that they will take a banned product and risk their health just to lose a few pounds.
