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.
That said, be careful of bilberry leaf tea and extracts made from the bilberry leaf as they may contain toxins that you donât want in your body in high doses. To get a little bilberry into your healthy diet, consider using the fruit in healthy cucumber and berry juice.
