Cinnamon
Powdered cinnamon has the ability to lower blood sugar levels by stimulating insulin activity. It contains bioactive components that can help prevent and fight diabetes.
Certain trials have shown that it can work as an effective option to lower blood sugar levels in cases of uncontrolled type-2 diabetes.
Cinnamon, however, should not be taken in excess because we commonly use Cassia cinnamon (found in most grocery stores) which contains a compound called coumarin. It is a toxic compound that increases the risk of liver damage.
There is another variety of this herb known as Ceylon cinnamon or “true cinnamon.” It is considered safer for health but its effects on blood glucose levels have not been studied adequately.
