Herbal products contain too many unlisted ingredients

IF you’re a fan of natural health products, a new study suggests using caution – Canadian researchers have found that “the majority” of herbal products on the market contain ingredients not listed on the label.

Researchers from the University of Guelph in Ontario used DNA barcoding technology to test 44 herbal products sold by 12 companies, finding nearly 60% of the products contained other plants or herbs not listed on the label.
