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
Chelation therapy is performed on an outpatient
On my last day of vacation in Italy, a chatty café owner in Rome introduced me to a tall, charming Italian man. He was a local artist, I learned; his name was Marco. Just a day earlier, my friend Lynn and I had sat in a piazza in Florence talking about how hard it is to meet nice guys. It had been two years since my last relationship, and, admittedly, I'd grown a little standoffish with the opposite sex. Lynn and I agreed that I could open up a little more. So when I met Marco, I figured...
Chelation is a
very effective way to treat heavy-metal poisoning. The U.S. Food and Drug
Administration (FDA) has approved prescription chelation therapy for the treatment of lead
poisoning. Injected EDTA binds with the harmful metal and both are then
eliminated from the body through the kidneys.
professionals have also used chelation therapy to treat
coronary artery disease, although there is not enough
scientific evidence to prove that this treatment is effective. Some people
believe that EDTA binds with calcium deposits (the part of plaque that
obstructs the flow of blood to the heart) in the arteries, and then EDTA
"cleans out" the calcium deposits from the arteries, reducing the risk of heart
problems. Research results have been inconsistent. Chelation therapy should not replace lifestyle changes or standard treatments for coronary artery disease.
professionals also suspect that EDTA may act as an
antioxidant by removing metals that combine with
LDL cholesterol, which can damage arteries. The theory
is that when you remove metals that flow freely through arteries (such as
copper or calcium), you may slow down diseases such as atherosclerosis.
Research has not proved this theory. Some experts believe that EDTA could
remove calcium from healthy bones, muscles, and other tissues, as well as from
Many people report less pain from chronic
inflammatory diseases such as
scleroderma after chelation therapy. The theory is
that EDTA acts as an antioxidant, which protects the body from inflammation and
protects blood vessels. Again, this idea has not been proved by scientific
