Consumer Reports analyzed 12 echinacea products in the March 1999 issue, using a standard set by industry. Although the standard some manufacturers use is 4% phenolic compounds (caffeoyl-tartaric acid, chlorogenic acid, cichoric acid, and echinacoside), only three products, Vita-Smart by American Fare , One-A-Day Cold Season by Bayer, and Echinex by Sunsource approached this standard at 4.5%, 4%, and 3.9%, respectively. There was also variation among different bottles of the same brand (Anonymous, 1999). [Pg.142]
