( - White Plains, New York, December 16, 2013 - Supplements containing the herb turmeric or its key constituent, curcumin, are popular treatments for inflammatory diseases. However, ConsumerLab.comreported today that three of nine turmeric/curcumin supplements recently selected for testing failed to pass its quality review.
