Bilberries: The Berry that Enhances Vision

Bilberries are tasty, dark blue or purple berries that are related to the blueberry. Native to North America and Europe, the bilberry belongs to the Vaccinium family of herbs. This powerful berry is one of the richest sources of antioxidants, and has been shown to improve vision and symptoms associated with diabetes.

Both the berries and leaves of the plant are edible, although for regular consumption, it is better to avoid the leaves as there are chemicals in them that can cause liver inflammation. In times past, people ate the leaves or drank a tisane made from them. This concoction did lower blood sugar, but at the cost of liver inflammation. It is now recommended that only the berries be ingested.

The high concentration of anti-oxidants is in the berries. Bilberries are well known as a natural treatment for diabetes mellitus.

Bilberries contain concentrated quantities of a flavonoid known as anthocyanin. This potent antioxidant is known to shield blood vessels from damage caused by fats and calcium that circulate in the blood. They are known to have a beneficial effect on the miniscule capillaries that are often damaged by too much sugar in the blood. The anthocyanin enhances binding of harmful chemicals to themselves instead of to cells in the body. This process protects the innermost lining of the blood vessels from being damaged by oxidation chemicals.

This action of the bilberry may help prevent eye conditions common to diabetes, such as retinopathy and macular degeneration. It is also seen as helpful in other eye conditions including cataracts and night blindness. There is some evidence that this remarkable berry is also helpful in reducing the burning and tingling associated with diabetic neuropathy, which can cause extreme discomfort of the feet and hands.

The visual benefits of the bilberry were first noticed During World War II when British Royal Air Force pilots ate bilberry jam. They noticed that their night vision was sharper than usual whenever they ate the jam before starting their nighttime missions.

If you find a good source of bilberries growing near you, they can be picked when ripe and frozen. They freeze well so they can be eaten all year. This berry also makes a great jam, but the medicinal benefits are greatly reduced.

If picking wild bilberries is not possible, the best way to be certain of getting a consistent supply of the helpful anti-oxidants is by purchasing a regulated, commercial preparation of only berries. The bilberry fruit has no known harmful effects. (by: Sheryl Walters)

Bilberry (Vaccinium myrtillus) Benefits


Bilberry has a long medicinal history in Europe. It has been used to treat anything from kidney stones to Typhoid fever. During World War 2 British pilots noted that Bilberry jam before a flight dramatically improved night vision. Modern research now supports these claims.

Bilberry contains anthocyanosides which are potent antioxidants which strengthen blood vessels and capillary walls, improve red blood cells, stabalize 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 vasodialator that opens blood vessels and lowers blood pressure. Since the eyes have a high concentration of capillaries, bilberry may be particularly helpful in improving eyesight. The herb has been shown to improve night vision, slow macular degeneration, prevent cataracts and diabetic retinopathy. Scientific studies have shown improvement in the eyesight, circulation, angina, stroke and atherosclerosis. It is also used to improve varicose veins and has anti-aging effects on collagen structures.
Individuals with hardening of the arteries, diabetes, high blood pressure or other conditions that increase the likelihood of damage to the small blood vessels in the eyes are more likely to have serious vision problems as a result of blood vessel damage. Note that bilberry is taken by mouth to treat eye problems. It is not used as an eye drop.

Oral bilberry preparations are also used to prevent and treat a condition known as chronic venous insufficiency, which occurs when valves in the veins that carry blood back to the heart are weak or damaged.

Blood may collect in the veins of the legs and lead to varicose veins, spider veins, or sores on the legs. More serious results can include blood clots in the legs. Because bilberry may strengthen the walls of all blood vessels in the body. It may also relieve haemorrhoids.

In the past, dried bilberries have been used to treat diarrhea because the tannins it contains (1.5% and as much as 10%) act as an astringent to the gastrointestinal tract. An astringent shrinks and tightens the top layers of skin or mucous membranes thereby reducing secretions, relieving irritation, and improving tissue firmness. Tea brewed from dried bilberry fruits has also been used to soothe a sore throat or sore mouth tissue.

In folk medicine, bilberry leaf has been used to treat a number of conditions including diabetes. Limited evidence from a few animal studies shows that it may have a decreasing effect on blood sugar. Additionally, in at least one study, an extract of bilberry leaves may also have lowered cholesterol levels in laboratory animals. Other laboratory and animal studies have tested potential anticancer effects of bilberry. In a laboratory study, bilberry stopped the growth of both leukemia and colon cancer cells. While preliminary results suggest that anthocyanosides obtained from bilberries may also block the effects of an enzyme and other chemicals that promote tumor growth, much more study is needed. To date, no human clinical studies have confirmed any of these results from bilberry.

Recent research showed that Bilberry extract has promising anti-ulcer activity, both preventive and curative. It also has shown anti-cancer properties in animal experiments. When administered to diabetes patients, Bilberry normalised capillary collagen thickness and blood sugar levels in humans and animals. (herbwisdom)
