Fluoride Action Network

Abstract

As described recently in Fluoride, horses on artificially fluoridated water (AFW) developed chronic fluoride poisoning. This report describes an allergic manifestation as an addition to the classical signs of fluorosis, viz., urticaria. The skin lesions disappeared promptly when an affected horse was removed from AFW and returned promptly when the horse was returned to AFW. These reversible changes attest to the highly allergenic potential of fluoride.
