The bilberry, which is related to the blueberry and cranberry, is rich in flavonoids called anthocyanosides. These flavonoids strengthen blood capillaries and improve circulation. Anthocyanosides reduce and reverse damage to blood vessels, as well as prevent blockage of coronary arteries.

The carotenoids found in bilberries help with a wide range of eye and vision problems. It is thought to improve night vision. In fact, World War II fighter pilots ate bilberries before flying to improve their night vision.

In a 2003 issue of European Journal of Clinical Nutrition, researcher Iris Erlund showed evidence that bilberries contain the flavonoid quercetin. Quercetin, also found in red wine, has anticarcinogenic, antioxidative, and enzyme-inhibiting properties. In a 2004 issue of Insight, the Journal of the American Society of Ophthalmic Registered Nurses, quercetin was found to play a role in preventing macular degeneration.

Other benefits of the antioxidants found in bilberries are its anti-inflammatory actions. The bilberry is used to treat urinary tract infections. The anti-inflammatory properties prevent bacteria from adhering to the walls of the urinary tract. The anthocyanosides in bilberries may also have anti-ulcer properties by preventing the ulcer causing bacteria from attaching to the stomach lining.

Bilberries have been used for centuries to treat diarrhea. In the 16th century the bilberry fruit was combined with honey to make a syrupy mixture used to cure diarrhea and other stomach ailments.

Bilberries are native to Europe and parts of North America. They are only found in the wild, as there is no cultivation of the fruit for commercial purposes. Bilberries are difficult to find as a berry, but are more common in jams, jellies, and syrups. A bilberry extract is another way to get the nutritional benefits of this antioxidant packed fruit. It can be purchased in many health food stores or online on websites that specialize in health food or nutritional supplements.
