How does Ephedra Work?
Ephedra is a plant made up of several sterols and chemical compounds, but the two wthe weight watcher are concerned with are ephedrine and pseudoephedrine. These are plant alkaloids that are thought to be responsible for the ephedra's thermogenic or fat burning action. These alkaloids are believed to cross the barrier protecting the brain from unwanted chemicals in the blood and mimic activity of the sympathetic nervous system ("fight or flight") by interacting with various neurotransmitter receptors. Specifically, it is thought to enhance the release of the neurotransmitter norepinephrine and stimulates alpha- and beta-adrenergic receptors.

The problem with this non-specific stimulation of adrenergic receptors is that while the desired receptors (beta-2) in the lungs are stimulated to open the airways, other types of receptors are also stimulated, including the beta-1 receptors in the heart that increase heart rate and force of contraction, and the alpha-1 receptors that increase blood pressure and decrease circulation to the renal system and other parts of the body.
While this is a potent herbal supplement, used with caution and restraint, it can be consumed safely and effectively, as exemplified by the billions of servings consumed before the ban,
