Bilberry (Vaccinium myrtillus L.)
Ericaceae Heath family
Bilberry is a perennial, ornamental shrub that is commonly found in various climates in damp woodlands and moorlands. In the United States they are known as huckleberries, and there are over 100 species with similar names and fruit throughout the Europe, Asia and North America. The English call them whortleberries. The Scots know them as blaeberries. Bilberry has been used as a medicinal herb since the 16th century.
Bilberry is also used in connection with vascular and blood disorders and shows positive effects when treating varicose veins, thrombosis, and angina. Bilberry’s fruit contains flavonoids and anthocyanin, which serve to prevent capillary fragility, thin the blood, and stimulate the release of vasodilators. Anthocyanin, a natural antioxidant, also lowers blood pressure, reduces clotting and improves blood supply to the nervous system. Bilberry also contains glucoquinine that has the ability to lower blood sugar.
The herb contains Vitamins A and C, providing antioxidant protection which can help prevent free radical damage to the eyes. Vitamin A is required for sharp vision, while Vitamin C helps form collagen and is needed for growth and repair of tissue cells and blood vessels. Anthocyanosides support and protect collagen structures in the blood vessels of the eyes, assuring strong, healthy capillaries that carry vital nutrients to eye muscles and nerves.
Bilberry has long been a remedy for poor vision and “night blindness.” Clinical tests confirm that given orally it improves visual accuracy in healthy people, and can help those with eye diseases such as pigmentosa, retinitis, glaucoma, and myopia. During World War II, British Royal Air Force pilots ate Bilberry preserves before night missions as an aid to night vision. Bilberry works by improving the microcirculation and regeneration of retinal purple, a substance required for good eyesight.
Dried Bilberry fruit and Bilberry tea has been used as a treatment for diarrhea and as a relief for nausea and indigestion. Bilberry is also used as a treatment for mild inflammation of the mucous membranes of the mouth and throat.

Also the fruit is used for anemia, consumptive wasting, indigestion, and colitis. Roots are used for dropsy, and urinary stones. Dried berries pass through the stomach without affecting it; beginning work in the small intestine. A strong decoction of the berries is said to be used for typhoid fever. Fresh or well-preserved berry juice makes a good gargle for sore throats or as a mouthwash for inflamed gums or for leucoplasia (an inflammation of the tongue producing white patches). Eating the fresh berries help regulate bowel action, stimulate appetite, end intestinal putrefaction which causes gas. Leaf tea used for coughs, vomiting, stomach cramps, and catarrhal enteritis. Externally, use as a wash for skin problems, sores, wounds, ulcers, and burns. Strengthens capillaries that feed eye muscles and nerves reducing and even reversing the damage caused by blood vessel deterioration. Increases night vision, reduces eye fatigue, helpful for nearsightedness (myopia). Helps preserve eyesight and prevent eye damage. At one time, it was used in the treatment of scurvy in Norway and other northern countries.

Legends, Myths and Stories
Bilberry is a well-known folk remedy for poor vision, especially for people who suffer from “night blindness,” that is, they have difficulty seeing in the dark. In fact, bilberry jam was given to Royal Air Force pilots who flew nighttime missions during World War II. It works by accelerating the regeneration of retinol purple, commonly known as visual purple, a substance that is required for good eyesight. European medical journals are filled with studies confirming bilberry’s positive effect on vision. Unfortunatley, this herb has not received the attention it deserves in the American medical community so far.
Used to make wine.
Elizabethan apothecaries made a syrup of the berries with honey, called rob, as a remedy for diarrhea.
