Statistics from the American Association of Poison Control Centers show that no deaths were caused by dietary supplements in the USA in 2008.
This includes all herbal supplements.
2009 figures show similar figures.
An article on therapeutic nutrition site Orthomolecular.org asks,
“If nutritional supplements are allegedly so dangerous, as the FDA [US Food and Drug Administration] and news media so often claim, then where are the bodies?”
Meanwhile, the FDA’s own Adverse Event Reporting System shows nearly 64,000 deaths attributed to orthodox medicines in 2009 alone.
