Used for years in the treatment of mercury and lead poisoning, alternative medicine practitioners and some doctors have recently embraced EDTA chelation therapy to treat stroke and heart disease. However, the American Heart Association does not recommended chelation therapy for the treatment of heart disease.
EDTA (ethylenediaminetetraacetic acid) chelation therapy is a type of treatment that involves a chemical substance (EDTA) being administered intravenously in order to remove toxins (such as heavy metals like mercury, cadmium and lead) from the bloodstream. As for the term chelation, "chelate," is extracted from the Greek root "chele," which is the term for "to claw." As with any type of therapy, there are some possible side effects associated with EDTA therapy.
