There have been reports that the curcumin-like polyphenols have pharmaceutical properties, including helping control inflammatory responses, degenerative eye diseases, and even metabolic syndrome. Polyphenols are plant metabolites that help protect plants from ultraviolet rays, insects, bacteria and even viruses. They are also a source of bitterness, acidity, color, flavor, and oxidizing power.
