    2, anti-radiation effects: can inhibit radiation-induced lipid peroxidation.

    3, anti-inflammatory effect: the main component is proanthocyanidins, its antioxidant activity can inhibit such as histamine, 5-hydroxytryptamine, prostaglandins and leukotrienes and other inflammatory factors such as synthesis and release, inhibit the release of particles from basophilic cells and mast cells, but also inhibit the activity of histamine decarboxylase, limiting the role of hyaluronidase.
