Polyphenols are the most abundant group of plant phenolic compounds, known to provide much of the flavor, color, and taste to fruits, vegetables, seeds, and other parts of the plants. As dietary sources of biologically active compounds they prove to be valuable for health. They have been linked to reduce the risk of cariovascular disease, cancer, and other degenerative diseases. Commercially available grape seed and skin extracts are a rich source of these polyphenols. The various health benefits of polyphenols have been associated with their antioxidant, antibacterial, anti-inflammatory, and anti-allergenic properties.
