Look for the "USP"
Nutritional supplements are classified as food products, so the FDA does not regulate them. Manufacturers can sell them in any quantity or combination they want, with little quality control. The pills might not even contain the substance claimed. Always look for a small "USP" on the label. This means that the United States Pharmacopeia, a reliable nonprofit science organization, has tested and verified the supplement. Check out the U.S. Pharmacopeia's website at USP.org to get more details.

Unfortunately, the very few studies on echinacea in Germany and the United States have produced mixed results. And a few even hinted at negative affects. You might be better off putting your money toward a piping hot bowl of chicken soup, which has been proved beneficial by scientific research and grandmas everywhere.
