Native to Eurasia and North America, the dark blue berries and leaves of the bilberry bush have been used medicinally for eye conditions, diabetes, diarrhea, mouth inflammation, urinary issues, and scurvy prevention (thanks to their high vitamin C content) since the Middle Ages.
Research has shown bilberries are high in antioxidants and are useful for reducing inflammation, particularly in the eyes, including the retina and small capillaries. It’s often used to improve night vision and reduce light sensitivity and eye fatigue. Some have even used it to help cataracts, varicose veins and other conditions, like atherosclerosis (plaque build-up in the arteries).
