It is excellent that you didn't get any amalgams when you were younger, that would have been a big obsticle to correct ,you are one step closer to being toxic free and if there is any damage from the toxins most if not all can be reversed once the toxins are lowered or removed completly ,about your autistic child, has your child ever been exposed to large amounts of pestisides or thimerosol in vaccines, there is a good chance that that could be the source ,but there is a product that is supposed to help with natural detox it is called pca-rx from maxam labs and is showing some promise in autistic children,
