Description:Ripe grapes naturally contain a high content of antioxidant catechins as well as proanthocyanidins. The taste and properties of wine, especially red wine, is due to its content of polyphenols. Recently, it has been postulated that the low death rate from coronary heart disease in southern France is directly related to regular consumption of polyphenols from red wine (Frankel, E.N. 1993). While the medicinal use of grape seeds dates back only to the 1920s, people have been consuming grapes for thousands of years in the form of wine. The active constituents in grape seeds, antioxidant polyphenols, catechins, and proanthocyanidins, are present in many plants which have a long history of medicinal use.
