U.S. health regulators warned Hain Celestial Group Inc about a potentially unsafe herb in some of its herbal teas, saying it might be dangerous to blood sugar, reproductive, cardiovascular and renal systems.
The U.S. Food and Drug Administration sent a letter to Hain dated August 17 calling the herb, a natural sweetener made from a South American herb called stevia, "an unsafe food additive." The agency released the letter on its Web site on Tuesday.
