Bilberry Uses and Health BenefitsThe bilberry was used in the past to help treat scurvy (a condition once common among sailors because of the lack of fresh fruit and, specifically, vitamin C). These days, the bilberry is used for many issues, including diarrhea, menstrual cramps, and circulation problems. The leaf of the bilberry plant also is sometimes used to treat diabetes. Basically, the fruit is eaten whole or made into extracts, whereas the leaves are used in teas (and extracts).
Bilberry – Does It Work?Well, that’s a tough question. No one has really bothered to research it. Chances are it does some good, much like the blueberry, but that the claims have been exaggerated. The bilberry is a fruit and is good for you. As long as you stick to eating the fruit, there haven’t been any side effects reported. Be careful of bilberry leaf tea and extracts made from the bilberry leaf. Those contain toxins that you don’t want in your body in high doses.
