Herbal Supplements Missing Key Ingredients

Posted: Updated:

A new report claims some herbal supplements may not actually contain herbs.

The New York Times reports recent DNA testing by Canadian researchers shows 1 out of 3 herbal supplements tested had no trace of the supplements at all. And many others were mostly cheap fillers like powdered rice and weeds.

The study looked at 44 bottles of popular supplements sold by 12 companies.

A nonprofit group that supports herbal supplements says quality control is an issue, but not as bad as in this study.

The findings of the study are published in the Journal BMC Medicine.
