Herbal product contamination ‘considerable,’ DNA tests find

10

A DNA test of herbal products has found that most of them contained cheaper fillers and plant ingredients not listed on the label, some of which pose "serious health risks."

Researchers at the University of Guelph used DNA barcode testing to test 44 herbal products from 12 companies. DNA barcoding uses a short sequence of DNA from a standard segment in plants to identify the species rapidly and accurately.

"Product substitution occurred in 20/44 of the products tested and only 2/12 companies had products without any substitution, contamination or fillers," Steven Newmaster, an integrative biology professor at the University of Guelph and his co-authors concluded in Friday's issue of the journal BMC Medicine.

"Some of the contaminants we found pose serious health risks to consumers."

      Called cut ti the addict that burns through is hard earned money for the needed fix.

      Have you been taking anything recently, by any chance? It´s certainly impaired your ability to write a coherent sentence.

  1. In addition St. John’s wort suppresses the effect of most medications.

    Somehow we need to get these things tested for effectiveness, and ban bogus claims. The catch is, who would pay? These are not $10 a pill pharmaceuticals.

      We need to get these things tested for safety. Anything after that is the necessary freedom of adult idiots to be idiotic. If, however, they are to be allowed for use on children they should be tested for efficacy also and become fully medically controlled, being restricted from child use where incorrect use, eg being less effective than conventional treatments, may be harmful. If this takes a dollar a pill or ten dollars, so be it.

  2. Herbalism is a very fertile area for medicinal fraud!
    Just collect and dry some non toxic plants and perhaps chuck in a few mgs of something like Atropa belladonna (for its anticholinergic effect) and charge plenty of money!
    All these businesses rely on tidal bullshit!
