Bilberry (Vaccinium myrtillus) is a shrub found in the mountains of Europe and North America. It 'similar to the North American cranberry and blueberry. The shrub, a blue black or purple berries, with pulp purple from July to September, depending on altitude. This berry is part of the plant of interest. In addition to its use as food, has been used as kidney stones, gall to treat scurvy problems, cough and tuberculosis documented in 1500. Healso used for a traditional tea to treat diabetes, and reported a hypoglycemic effect. Little is known about the active constituents and their pharmacology blueberry known, although it has been studied since at least 1964 for ophthalmic and vascular disease.
Most of these studies have been conducted in Europe, and many are published in obscure journals or non-English. Stories of the British Royal Air Force pilots eating bilberry jam during World War II to improve their night visionmay have led some of these studies. In the U.S., usually in the form of cranberry capsules and sold as an antioxidant to promote eye health. It is sometimes said with other vitamins or herbs to be helpful, the eye, as the lutein and eye comfort combined.
Bilberry may enhance the capacity for synthesis of connective tissue glycosaminoglycans, the basic mechanism are its beneficial effects in various diseases. Its gastroprotective, healing and vasoprotectiveAll these extracts had action.Billberry expression of vascular endothelial growth factor by human keratinocytes in vitro to inhibit. This suggests that blueberries or its components have a role in cancer prevention or treatment.
Bilberrry could limit the 'acute effect of Triton on triglycerides, suggesting that blueberries improve the clearance of lipoproteins, but does not affect the production of lipoproteins. Although cranberry has an effect similar to that of triglycerides asFibrates (eg gemfibrozil, fenofibrate) therapy for the treatment of hypertriglyceridemia, has no effect on the size of blueberries or thrombus composition, suggesting that possesses anti-thrombotic, as demonstrated with some fibrates.
Oxidized low-density lipoprotein (LDL) is known for its ability to stimulate inflammatory processes in the formation of atherosclerotic plaques known. For this reason, there has been interest in theTo protect the use of antioxidants as blueberries against LDL oxidation.
Eating blueberry jam night vision device to the suspected pilots of the Royal Air Force within 24 hours of bilberry jam to improve, and at least five European studies, the positive effect of bilberry on night vision were published before 1970. A 1997 study published in summary Israelis found negative results, carried out as a recent study conducted in 15 Navy Seals. In this study, the courage and his colleagues describe the effect ofBilberry Extract (25% anthocyanocides) 160 mg three times daily for 3 weeks at night corrected visual acuity and contrast sensitivity in subjects with night vision at least 20/20.
An independent laboratory analyzed the composition of the extract used. Eight and seven placebo subjects in the extract were given double-blind fashion. After 30 days washout, subjects were switched to the alternative treatment arm. Night visual acuity and contrast sensitivitySensitivity to light conditions were measured in simulated moonlight. These studies have shown that bilberry improves night vision, adjusting to the dark, and the restoration of visual acuity after the transition.
Currently there are no reports of adverse effects from eating blueberries or related compounds. When the fruit is contained in the usual amounts consumed in foods, blueberry is classified generally recognized as safe by the U.S. Food and DrugAdministration.
