I'm tring trying to find info on possible link of fibro pain to nightshade vegetables reactions in some people. One article said that a chemical used to conduct electrons in nerves was then broke down by an enzyme. The inhibitor effect of cholintesterase (?) on the enzyme formation prevented the breakdown of the transport (?) chemical. This had the effect of a note being played, but never ending on the nerve ending. I can not find that article agin an would like some confirmation of the science of this line of thought.
