The Associated Press is reporting that the U.S. government’s largest ever alternative medicine study has stopped enrollment while “officials investigate whether participants were fully informed of the risks and are being adequately protected.” Over 1,500 heart attack survivors are involved in the $30 million research, which is testing chelation therapy, a controversial treatment typically used in lead poisoning.
