Ozone is a three-fold application in that it is germicidal, removes toxins and stimulates metabolism. In the case of autism there is growing evidence of gastrointestinal infections in which I would recommend Metametrix GI Effects stool test - it is quite possible that the application of ozone could be beneficial in these circumstances via rectal insuflation etc. Toxins (heavy metals etc) could be a contributing factor in ADD/ADHD in which ozone could help remove with other modalities.
