Specifications：25% Assay Method：UV/HPLC Herb Source：Bilberries are basically the European version of the American blueberry Brief：Deep purple fine powder Pharmacology：Modern laboratory studies on bilberry fruit extracts have confirmed a number of activities including antioxidant effects, an ability to inhibit aggregation of blood platelets (reduce stickiness, hence a tendency to clotting of blood cells), produce a slight relaxation effect on vascular smooth muscles, and a possible role in reducing factors associated with chronic inflammatory diseases. Extracts of the fruit have also been shown in laboratory experiments to inhibit enzymes such as elastase, which can cause the degradation of collagen. This can lead to a reduction in factors associated with inflammatory conditions such as atherosclerosis, pulmonary emphysema, and rheumatoid arthritis.
