The American Heart Association is calling for a ban on over the counter products containing Ephedra. The Heart Association says these non-regulated products do more harm than good and should be pulled from the market. Meantime, it's urging customers to talk to a doctor before using Ephedra products. Ephedra has been linked to high blood pressure, strokes, heart attacks and even death. A recent study found that Ephedra increases the risk of problems like palpatations, psychiatric and gastrointestinal symptoms as much as three-fold. The reseasch, conducted at the Rand Institute, also found little evidence of Ephedra's power as a long-term weight loss aide or a performance enhancer. The Heart Association submitted it's appeal to the Food and Drug Administration. Earlier this year, the FDA proposed limits on the marketing of Ephedra-based dietary supplements.
