Chelation is an approach that aims to way to remove toxins from the body such as lead or mercury that are thought to be antecedents to autism. Chemicals are ‘flushed’ from the body with a range of other chemicals and it can be a long and drawn out process.
In the US the FDA has issued a caution against do-it-yourself chelation kits as there is some evidence that it can cause harm if not done properly. It can be distressing for the autistic child as well as dangerous, and is not recommended.
