"It is not approved by the federal government for treating autism, though the Food and Drug Administration has approved it for treating lead poisoning."

Hmmm, let me see now. My son who has autism has lead poisoning. Turns out the vaccines he was administered by his pediatricians screwed up his methylation so thoroughly, that it left him incapable of detoxifying (the environmental exposure he sustained over the years) on his own.

Oopsy daisy, now I get it - the FDA does not want folks to see mercury from the vaccines pouring out, so therefore its better to keep saying its "experimental and unproven." Silly me.
