It is based on the chelation process, in which chemicals are used to remove heavy metals and other substances from the body. Although chelation was originally used to treat conditions such as lead poisoning, chelation therapy is now claimed to protect against heart disease and other major health problems. (Autism, Alzheimer’s disease, Band keratopathy, Multiple sclerosis, Peripheral arterial disease, etc.)
In the therapy, a chelating agent is introduced into the body through an intravenous (IV) drip or an oral pill. Once it enters the bloodstream, the agent binds to certain molecules (such as metals or minerals) and is eliminated from the body through urine, taking those molecules with it. One of the most common chelating agents used in therapy is ethylenediaminetetraacetic acid (EDTA). EDTA is known to remove substances such as lead, iron, copper and calcium from the blood.
