Chelation is a process of removing toxic substances from the human body. It has been accepted and approved by the US FDA. The origin of the word chelation comes from the Greek word chele, which literally means claw.
The principle of removing harmful metals from the body by chelation is based on the concept that there is a particular type of amino acid complex called EDTA (ethylene-diamine-tetra-acetic acid), which when in contact with metals that are positively charged and other metal elements like iron, cadmium, magnesium, zinc, plutonium, calcium, copper and manganese, has the ability to catch or grab very similar to a claw and helps in removing the harmful metal through the intestinal tract. This process can be done through application of various injections intravenously or it can be done by consuming certain types of herbs that have the chelating properties.
EDTA has been in the use by medical practitioners since the 1940s. It was then primarily used for the treatment of heavy metal poisoning. Its utility has become widespread. EDTA is also used for treatment of hyper calcemia and the control of ventricular arrhythmias, which is connected with digitalis toxicity. Later in the 1960s, scientists realized the potential of chelation therapy and used it for curing occlusive vascular disorder which happens because of arteriosclerosis.
EDTA has the ability to attract or grab metallic cations like lead and calcium from the body and forms a stable compound which can be easily excreted by the human excretion system. The process of chelation therapy can be well compared with that of clearing blockages in a drain with the help of a chemical.
