What do you think about this product:
When my daughter was 2, many people thought she was autistic.
She had a preliminary evaluation and was referred for further evaluation.
I tried the "wheat-free, dairy-free" diet for a few months, with no noticable change.
Then I started dosing her up on cilantro extract (which I bought at Whole Foods Market) every day in her juice and adding fresh cilantro to any food I could. Her behavior significantly improved. She used to throw tantrums that literally lasted all day (not every day). She used to torture the dog, her older brother, and anyone else in her reach by biting, hair-pulling, throwing things, etc.
By the time the "experts" got around to her full evaluation (state agencies are really slow - it took a few months), they were not really sure what to make of her. She was diagnosed with "Sensory Processing Disorder"; one of the occupational therepists didn't think there was anything wrong with her at all.
She is currently 3 years old and in a special needs school. Her teacher says she is doing really well. Next school year, she will spend part of her day in the class with the kids who only have speech delays and not other "special needs".
I don't give her the cilantro extract anymore but I still put fresh cilantro in everything possible. I am planning to order the product I linked to above. I am having some problems ordering it via internet because I live out of the US now, but I am working with their customer support. Of course, I plan to test it out on myself first (I would never give my children any medication that I wouldn't take myself - I also ascribe to the philosophy that you should never give a sick person something that you wouldn't give a healthy person).
Another option I am looking into is Ginko Biloba, which is supposed to increase circulation to the brain, thereby allowing you/your blodd to detoxify yourself.
