Hypoglycemia, also known as low blood sugar, is when blood sugar decreases to below normal levels. This may result in a variety of symptoms including clumsiness, trouble talking, confusion, loss of consciousness, seizures, or death. A feeling of hunger, sweating, shakiness, and weakness may also be present. Symptoms typically come on quickly.
Tea brewed from dried bilberry fruits has also been used to soothe a sore throat or sore mouth tissue. In folk medicine, bilberry leaf has been used to treat a number of conditions including diabetes. Limited evidence from a few animal studies shows that it may have a decreasing effect on blood sugar.
Print. Often called European blueberry, bilberry is closely related to American blueberry, cranberry, and huckleberry. Its meat is creamy white instead of purple, but it is traditionally used, like blueberries, in the preparation of jams, pies, cobblers, and cakes. Bilberry fruit also has a long medicinal history. In the twelfth century, Abbess Hildegard of Bingen wrote of bilberry's usefulness for inducing menstruation.
