Bilberry, also known as European blueberry, is an herb from a shrub that produces dark purple berries toward the end of summer. The bilberry is related to the blueberry, cranberry, and huckleberry. The entire plant is used for herbal medicines.

This herb contains anthocyanosides, compounds that benefit the circulatory system. Bilberry may strengthen blood vessels and connective tissue, build strong capillaries, and improve circulation. It may help to control the formation of blood clots, varicose veins, and hemorrhoids.

Additionally, these compounds (anthocyanosides) may help eyes adapt to light changes and enhances night vision.

Tannin, found in dried bilberry berries, may help to control diarrhea and related intestinal inflammation. Extract of bilberry may protect the stomach against digestive acids because it stimulates the production of stomach mucus.

The leaves of the bilberry are high in chromium – which may help regulate blood sugar levels. This may benefit people who are diabetic or hypoglycemic.
