Curcumin, is an anti-inflammatory molecule in the turmeric root, a relative of ginger. Turmeric has been used for thousands of years as a medicinal preparation and a preservative and coloring agent in foods. Curcumin was isolated as the major yellow pigment in turmeric; chemically diferulomethane, and has a polyphenolic molecular structure similar to other plant pigments (eg. extracted from grapes in wine (resveratrol), or in green tea (catechins) or in certain fruit juices (blueberries, strawberries, pomegranates etc.)
