what is chelation treatment
Chelation therapy is a chemical process in which a synthetic solution-EDTA (ethylenediaminetetraacetic acid)-is injected into the bloodstream to remove heavy metals and/or minerals from the body. Chelation means to grab or to bind.. When EDTA is injected into the veins, it grabs heavy metals and minerals such as lead, mercury, copper, iron, arsenic, aluminum, and calcium and removes them from the body. Except as a treatment for lead poisoning, chelation therapy is controversial and unproved.
