Bilberry contains properties that help strengthen the blood vessel walls. The extract is sometimes taken orally to reduce the size and soreness of varicose veins and hemorrhoids. It can treat chronic venous insufficiency, wherein the valves in the veins of the leg become damaged and unable to sufficiently carry blood back to the heart. This can cause itching, pain, and swelling in the leg, as well as skin ulcers. Anthocyanosides help boost the integrity of your vein's walls, reducing blockages and improving circulation.
