Historical or traditional use: The dried berries and leaves of bilberry have been recommended for a wide variety of conditions including scurvy, urinary tract infections, and kidney stones. Perhaps the most sound historical application is the use of the dried berries for the treatment of diarrhea. Modern research of bilberry was partly based on its use by British World War II pilots, who noticed that their night vision improved when they ate bilberry jam prior to night bombing raids.
Active constituents: Anthocyanosides, the bioflavonoid complex in bilberries, are potent antioxidants1. They support normal formation of connective tissue and strengthen capillaries in the body. Anthocyanosides may also improve capillary and venous blood flow.
How much should I take? Bilberry herbal extract in capsules or tablets standardized to provide 25% anthocyanosides can be taken in the amount of 240-480 mg per day or 1-2 ml two times per day in tincture form.
Are there any side effects or interactions? In recommended amounts, there are no known side effects with bilberry extract. Bilberry does not interact with commonly prescribed drugs, and there are no known contraindications to its use during pregnancy or lactation.
