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.
In 2009, another trial studied hibiscusâs ability to support cholesterol maintenance, this time in people concerned with healthy blood sugar levels. Sixty subjects, mostly women, were given either one cup of hibiscus tea or black tea twice per day. After one month, hibiscus was able to help maintain total, LDL, and HDL cholesterol levels â as well as triglycerides â already within a healthy range.* Black tea, on the other hand, only impacted HDL levels.
