Chelation: This is a treatment for heavy metal poisoning. Ethylenediamine Tetraacetic Acid (EDTA) is injected into the blood, which binds the metals, allowing them to be removed from the body in the urine. Although Chelation therapy has not been approved by the FDA to treat coronary artery disease, some physicians and alternative medicine practitioners have used it in this way. The first large-scale, multicellular study to determine if EDTA chelation therapy is beneficial for people with coronary heart disease was begun in August, 2002. The study will take about 5 or 6 years to complete.
For more than 30 years chelation has been hailed as a "miracle cure" although the FDA and American Heart Association have spoken out against such therapies. The man made amino acid EDTA (which binds the poisons to be removed) also binds calcium removing it from blocks in arteries. The reason for the FDA and American Heart Association's hesitance for recommending the therapy is that there has been no actual scientific proof that it works correctly and without harmful side effects after treatment.
