Bilberries (Vaccinium myrtillus) are known for their phytochemicals, most importantly polyphenols like anthocyanins. Bilberries are used in both food and pharmaceutical industries. Vaccinium myrtillus contains anthocyanosides in a concentration ranging from 0.1 to 0.25% in fresh fruit, flavonoids, pectin, vitamin C and tannins. Its extracts act as antioxidants and free radical scavenger, inhibit platelet aggregation, decrease vascular permeability and improve venous tone and blood flow.
