Function of bilberry extract: Bilberry is a perennial shrub native to Northern Europe, Northern America, and Canada, and has been used in these areas for diabetes and eye disorders for a long history. It is also mentioned in many olde texts in Buryatia, Europe and China as an herb valuable for it's powerful ability to correct many diseases of the digestive system, circulatory system and eyes. 

Bilberry is rich in anthocyanosides. Over 15 different anthocyanosides have been found in Bilberry. Anthocyanosides help to maintain the integrity of capillaries and to stabilize collagen. Anthocyanosides are also potent antioxidants. Numerous clinical studies have shown that Bilberry is effective in the treatment of circulation disorders, varicose veins, and other venous and arterial disorders.

The anthocyanosides protect veins and arteries by stabilizing the phospholipids of the endothelial cells and increasing the synthesis of collagen and mucopolysaccharides, which give the arterial walls their structural integrity. Anthocyanosides also prevent the aggregation and adherence of platelets to endothelial surfaces. Studies have also shown that Bilberry can act as a coadjutant in heme-ralopy and diabetic retinopathy by stimulating rhodopsin production.
