Positive findings of a safety study involving children and a highly touted botanical extract (COLD-fX) show promise for its future development for kids as a Canadian cold and flu remedy. COLD-fX, Canada's top selling cold and flu remedy for adults, is a patented extract of North American ginseng discovered by a team of 25 University of Alberta scientists. It has been approved by Health Canada for use by adults. And the FDA has cleared its sale as a new dietary ingredient (NDI) for adults in the U. S. This is the first time COLD-fX has been studied for pediatric use. The researchers report that they could find only seven other studies of natural health products (NHPs) for children as of 2007. The results of the trial come at a time when the FDA and Health Canada are reviewing the safety and efficacy of hundreds of children's cough and cold remedies sold in both countries.
