In chelation therapy, a dose of a medication called ethylenediaminetetraacetic acid (EDTA) is delivered through an intravenous (IV) line. This medication seeks out and binds to minerals in your bloodstream. Once the medication binds to the minerals, it creates a compound that leaves your body in your urine.

Chelation therapy is a proven treatment for lead or mercury poisoning. Some doctors think that chelation therapy could begin to reverse heart disease by binding to the calcium in the plaques clogging your arteries and sweeping it away. No study has proved that this process actually works.
