The American Botanical Council is a non-profit educational organization providing reliable information on the safety and efficacy of herbal medicines. Our main goal is to promote scientific research on medicinal plants and provide reviews on the safety and efficacy of botanical ingredients via our journals and publications. My work as Technical Director of the ABC-AHP-NCNPR Botanical Adulterants Prevention Program is focused on providing accurate information about herbal ingredient adulteration issues and the use of appropriate analytical methods to detect ingredient and finished product adulterations.
