Chelation therapy was first used during world war one by the British as a result of arsenic based poison gas used indescrimitively in that war. An organic dithio compound was used to bond with the arsenic in the bloodstream and exiting the body through the kidneys and liver. This therapy reportedly had severe side effects.

As with all chelation agents, there are many underlying purposes and the end result is a chemical bond with metal ions in the bloodstream making the ions less chemically active resulting in a water-soluble solution that is then naturally eliminated via the bloodstream.
Chelation therapy is now widely used to treat toxic metal poisoning. EDTA chelation, which is USDA approved, is the chelation agent most used by our medical industry.
I believe it is fair to say that conventional medicine and alternative medicine have been at odds for many years for various reasons and too many to mention here. Having said that both sides of medicine use chelation therapy, the difference is in the agent used.
Alternative medicine uses natural agents found in herbs, vitamins, minerals and natural sources. This includes EDTA, which is in fact the standard FDA approved chelation agent used for treating lead, mercury, aluminum, and cadmium poisoning.
