I read an article in a Health magazine  this summer on the art of NAET.  My
impression is that it is only practiced by a small handful of chiropractors and
acupuncture.  The chiropractor I was seeing this summer for a sore back said
she didn't know anyone that used it.  It was interesting reading but in our
case with children with anaphylactic food allergies I would never try it
because it seems awfully risky for us.
