A rich source of anthocyanins, bilberry contains powerful antioxidants and exerts a small hypoglycemic effect that may play a role in preventing cardiovascular and metabolic disease. Its root system, which reflects some similarities with human microcirculation, protects against soil degradation. Rich in tannins, bilberry young shoots have angio-protective qualities that improve microcirculation in cerebral, retinal and inner ear tissues. Birds are known to seek bilberries to aid with night vision.
