Amazon has pulled two “autism cure” books from its online marketplace, including one that suggests ingesting and bathing in a potentially toxic form of bleach. Amazon confirmed the books, Healing the Symptoms Known as Autism and Fight Autism and Win, are no longer being sold. The company didn’t say why they had been removed, but it comes after a Wired report criticized Amazon for offering pseudoscientific books that recommend dangerous methods for “reversing” autism. NBC News reports Healing the Symptoms Known as Autism praised the healing power of chlorine dioxide, a form of bleach that the Food and Drug Administration warns can cause “severe nausea, vomiting, and life-threatening low blood pressure from dehydration.” Fight Autism and Win tells parents that chelation—an unproven treatment that involves medicating a child with an antidote for mercury poisoning—can also cure autism.
