Herbal Medicine, Quality Control, and Adulteration Prevention: Mark Blumenthal, founder and executive director of the
American Botanical Council (ABC), recounts his entry into herbalism via vegetarianism in 1968, off-grid living, and starting a wholesale herb business in 1974 before shifting to nonprofit education, research, advocacy, and quality control. The discussion covers the evolution from teas and tinctures to standardized extracts, the complexity and synergy of multiple constituents, and how standardization supports quality control and therapeutic consistency. Blumenthal explains ABC’s Botanical Adulterants Prevention Program and its free, peer-reviewed resources addressing global fraud, plus GMP requirements and laboratory methods for identity, contamination, and potency testing. He discusses herbs including ashwagandha, turmeric/curcumin and adulteration risks, maca, nigella, and milk thistle, and outlines ABC resources, HerbClip, and membership options at herbalgram.org.
