What is Chelation?
The word Chelation is derived from the Greek word chele, which means ‘to claw’. The concept of chelation is based on the binding of positively charged heavy metals by an amino acid complex, EDTA, in a manner similar to the clawing action of a scorpion or a crab. Most commonly used chelators at our centre are EDTA and DMSA.
Chelation Therapy is a process of removal of toxic heavy metals from the body by the intravenous (IV) infusion or oral ingestion of an organic compound with appropriate chelating properties.
The most widely accepted use of chelation therapy in medicine is for the removal of toxic metals,such as lead, arsenic, cadmium, mercury, iron, copper or aluminum from the body. A more controversial, but clinically useful indication for chelation therapy, and more specifically disodium EDTA chelation therapy, is the treatment of all forms of atherosclerotic diseases, including,coronary, cerebral, and peripheral arterial disease as well as other degenerative conditions.
History behind Chelation Therapy
The chemical solution most often used in chelation therapy, EDTA, was first made in Germany in the 1930s. It is now widely accepted as an effective treatment for heavy metal poisoning.In the 1950s, some scientists theorized that EDTA could remove calcium from the body. Calcium can build up on artery walls, eventually causing heart disease, and it was theorized that use of EDTA could unclog blocked arteries. In some early studies, researchers reported positive results among patients with heart disease who received EDTA. Some said that chelation therapy relieved chest pain caused by blocked arteries. These first observations have not been confirmed by larger, more rigorous studies, but they led some practitioners to begin using chelation therapy for heart and circulatory problems and, later, for several other illnesses. It is estimated that tens of thousands of Americans currently undergo chelation therapy for heart disease
