If you buy certain herbalsupplements you may not be getting what you're paying for.
The first question is whether theherbal supplements actually work. The second is if there are any herbsin them at all.
The New York Times reported thatrecent DNA testing by Canadian researchers showed one out of three herbalsupplements tested had no trace of the labeled supplement at all.
Many others were found to be madeup mostly of cheap fillers like powdered rice and weeds.
The study looked at 44 bottles ofpopular supplements sold by 12 companies.
A nonprofitgroup that supports herbal supplements says quality control is an issue, butnot as bad as what was reported in this study.
