What is chelation therapy?
Chelation therapy consists of a series of intravenous infusions of disodium ethylene diamine tetraacetic acid (EDTA) in combination with other substances. It is promoted as a noninvasive means of improving blood flow in atherosclerotic vessels, and purported to result in regression of atherosclerotic plaques and relief of angina. However, the efficacy of chelation therapy in athero- sclerotic disease is not supported by clinical trials.
