Fluoride is a neurotoxin - think sarin gas. Among other things, it interferes with protein processes. If halothane and isoflurane are causing amyloid plaques, fluoride could be the culprit. I think we should all stay away from fluoride (see my thread on the fibromyalgia forum - "Fibromyalgia - A Likely Cause...")

I believe that neither propofol nor thiopental contains fluoride.
