3. Brief description
Bilberry is a shrub that grows to about 16 inches in height. It has oval, pointed leaves and small pink and white flowers, which bloom from April through June. In the late summer, its dark purple berries are ripe to pick. Bilberry is a relative of blueberry, cranberry, and huckleberry, and its fruit looks and tastes much like the American blueberry.
The key compounds in bilberry fruit are called anthocyanidins. These compounds help build strong capillaries and improve circulation to all areas of the body. They also prevent blood platelets from clumping together (helping to reduce the risk of blood clots which may lead, for example, to heart attack or stroke). On the other hand, bilberry fruit is also rich in tannins, a substance that acts as an astringent, thereby helping bleeding to stop. The tannins and anthocyanidins, therefore, may balance each other out when the whole bilberry fruit is used for medicinal purposes.
Anthocyanidins also boost the production of rhodopsin, a pigment that improves night vision and helps the eye adapt to light changes. The tannins have anti-inflammatory properties and may help control diarrhea.
4. Effects of bilberry
l Diarrhea and wounds
Bilberry (Vaccinium myrtillus) has been used in traditional European medicine for nearly a thousand years, primarily to treat diarrhea. Bilberry fruit contains high concentrations of tannins, substances that act as both an anti-inflammatory and an astringent. The latter quality in particular may help wounds heal more quickly. Bilberry is believed to help people with diarrhea by reducing the intestinal inflammation associated with the condition.
l Diabetes
Bilberry leaves have traditionally been used to control blood sugar levels in people with diabetes. A couple of modern day reports of a few individuals with type 2 (adult onset) diabetes as well as animal studies suggest that this traditional use may have merit. Rigorous scientific studies are needed.
l Antioxidants
A close relative of the cranberry, bilberry fruits contain flavonoid compounds called anthocyanidins. Flavonoids are plant pigments that have excellent antioxidant properties. This means that they scavenge damaging particles in the body known as free radicals and have been shown to help prevent a number of long-term illnesses such as heart disease, cancer, and an eye disorder called macular degeneration (a disease of the retina that can lead to blindness; see Visual Disturbances listed below). Animal studies have found that anthocyanidins may strengthen blood vessels, improve circulation, and prevent the oxidation of LDL ("bad") cholesterol, a major risk factor for atherosclerosis (plaque in blood vessels that leads to blockage and, therefore, heart attack and stroke). Research in people is needed.
l Chronic fatigue syndrome
Some experts propose that bilberry may relieve the symptoms of chronic fatigue syndrome because of its antioxidant properties.
l Ulcers
Studies in rats have found that anthocyanidins from bilberry fruits help prevent stomach ulcers caused by a variety of factors including stress, medications, and alcohol. Whether this will translate into help for people requires research.
