Extracts (Black Currant Fruit): - As a major source of the major COX-2 Inhibitor ([+]-catechin), this might be viewed by enthusiasts as another herbal miracle aspirin (COX). Anthocyanins and polyphenols in berries of several Ribes, Rubus, and Vaccinium spp. have in vitro antiradical activity on chemically generated superoxide radicals. The extracts also inhibit xanthine oxidase. All crude extracts were highly active toward chemically generated superoxide radicals. Ribes nigrum extracts exhibited most activity, being the richest in both anthocyanins and polyphenols. But Ribes rubrum extracts seem to contain more active substances (X1332092).
