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.

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.
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.
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.
Chronic fatigue syndrome
Some experts propose that bilberry may relieve the symptoms of chronic fatigue syndrome because of its antioxidant properties.
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.
Visual disturbances
Anthocyanidins found in bilberry fruits may also be useful for people with vision problems. During World War II, British fighter pilots reported that bilberries improved their nighttime vision and helped them quickly adjust to darkness. A recent study, however, comparing a bilberry extract of anthocyanidins to placebo in young men with normal vision did not confirm any improvement in night vision from this supplement. The study only included 12 men. Therefore, more research is needed to know whether the long standing stories of improvement in night vision from bilberry for some individuals is scientifically true or not.
Today, it is believed that anthocyanidins may help protect the retina, the nerve layer that lines the back of the eye and sends nerve impulses to the visual areas of the brain. Studies conducted in the 1960s, 70s, and 80s suggest that the anthocyanidins contained in bilberry fruit preparations improve symptoms of a variety of visual disturbances including nearsightedness, cataracts, and macular degeneration.

Bilberries may be eaten fresh or in dried forms. Fresh or dried berries as well as the leaves of the bilberry plant may be used to make bilberry tea. Bilberry extract should be standardized to contain 25% anthocyanidins. The extract contains the highest percentage of anthocyanidins, making it the most potent form of bilberry.

Bilberry has been used safely in children 2 years of age and older for the treatment of diarrhea:
4 to 8 grams of crushed, dried bilberry should be added to 150 mL (2/3 of a cup) of cold water and brought to a boil for 10 minutes; the preparation should be strained while hot. Children then drink this preparation several times daily until diarrhea resolves.
Adult
Diarrhea: 5 to 10 grams of crushed dried bilberries in 150 mL (2/3 of a cup) cold water, brought to a boil for 10 minutes, then strained.
Eye conditions and circulation: standardized bilberry extract (with 25% anthocyanidin) in encapsulated form, dosage of 480 milligrams a day in two to three divided doses. Reduce to 240 milligrams per day once symptoms improve (maintain this dosage to help prevent these conditions).
Diabetes: Pour boiling water over 1 g (approximately 1½ tsp) bilberry leaf and strain after 10 to 15 minutes. People with in particular diabetes should only drink bilberry tea under the supervision of a healthcare provider.
Ulcer prevention: 20 to 40 milligrams bilberry extract three times a day, 2 to 4 mL tincture (1:5) three times a day, or one half cup of fresh bilberries.

Because of the potential for side effects and interactions with medications, bilberry extracts and anthocyanidin preparations should be taken only under the supervision of a knowledgeable healthcare provider.
Bilberry fruit and extract are considered generally safe, with no known side effects. Bilberry leaf is safe with appropriate usage, but should not be taken in large quantities over an extended period of time because it may become toxic.
