The herbal remedy scam: Chris MacDonald

Time for the honest players to step up

A recent study by researchers at the University of Guelph used genetic analysis to study a range of commercial herbal remedies and found a shocking disparity between what was on the label and what’s actually in the bottle. It’s a quality control problem at best, and outright fraud at worst.

According to the Vancouver Sun, the researchers looked at 44 herbal products sold by 12 companies, using DNA ‘barcode testing’ to determine what plant species were in the bottle.

The result: some products contained other generally inert species of plants (for example, wheat or rice, to which some people are allergic), without those ingredients being listed on the label. Other products were adulterated with potentially toxic plants like St. John’s wort or senna. Others simply contained none of the active ingredient they were supposed to contain. And yet these products are commercially available at a major pharmacy chain near you.

The study, which was effectively about quality control within the industry rather than about naming-and-shaming particular companies, identified no one. But it’s a damning indictment for the industry quite generally. (Just two companies among the 12 in the study sold products that were just what they said they were.)

Of course, many readers will know that this is not the first reason we’ve had to doubt the integrity of the herbal remedy industry, or the ‘natural’ health product industry more generally. As others have written elsewhere (including pharmacists with the scientific and critical-thinking chops to know the difference), Canada’s regulations regarding natural health products leave much to be desired.

But it’s nothing to laugh about. Unlike homeopathic remedies, which (unless adulterated) generally contain no active ingredients at all, herbal remedies can have actual biological effects. This has been a source of pride for makers of herbals, situated as they are within an alternative-medicine industry that is rife with outright fraud and delusion.

But it also means that the honest bottlers of herbal remedies should be at the front of the line, lobbying government hard for stricter regulations. Perhaps even more crucially they should be doing their best to convince the major chains that there’s a difference between them and the companies whose products failed the Guelph study so miserably. In the end, it’s as much an ethical matter as one of self-interest. The public deserves to be better served, and who better than those within the industry itself to make sure that it happens?

  1. Would be interested to know who paid for this Study

    What we should be alarmed, and worried and mad at are the G.M.O’s that we have to deal with. They are much more harmful to us!

    • No, there is no credible avidence that GMOs in general are harmful. The Royal Society of Canada (an impartial expert body) published an exhaustive review several years ago and found no evidence of systematic danger. If you’re going to make claims like that, you should really back them up with credible evidence.

    • The link to the study is here: http://www.biomedcentral.com/1741-7015/11/222 That page notes that the authors declared no competing interests, which they could not have done if funded by a source with a financial interest in the outcome of the study.

      • According to the manuscript: “This research was supported by the grants to [the lead author] from the International Science and Technology Partnership Canada and Humanities Research Council of Canada, Genome Canada through the Ontario Genomics Institute, and the Canadian Foundation for Innovation.”

    • That’s entirely off-topic.
