Bilberry has a long medicinal history in Europe. It has been used to treat anything from kidney stones to Typhoid fever.
Bilberry contains anthocyanosides which are potent antioxidants which strengthen blood vessels and capillary walls, improve red blood cells, stabilize collagen tissues such as tendons, ligaments and cartilage and has cholesterol lowering effects. They also increase retinal pigments that allow the eye to tolerate light. In addition, it helps to maintain the flexibility of red blood cells, allowing them to pass through the capillaries and supply oxygen. The herb has been shown to be a vasodilator that opens blood vessels and lowers blood pressure.
