An herbalist is a professional trained in herbalism, the use of herbs (also called botanical or crude medicine) to treat others. Professional herbal designations include the American Herbalists Guild Registered Herbalist (AHG)[4] or the NCCAOM Diplomat in Oriental Medicine from the National Certification Commission for Acupuncture and Oriental Medicine[5] or the MNIMH of the National Institute of Medical Herbalists.[6] Lay herbalists and traditional indigenous medicine people generally rely upon apprenticeship and recognition from their communities in lieu of formal schooling.
