There is some compelling evidence that cinnamon (Cassia Cinnamon) can lower blood glucose and cholesterol levels in people with type II diabetes. Cinnamon is native to areas of Asia. The bark of the tree is used for seasoning and in Traditional Chinese Medicine for its healing properties. A 2012 Chinese study looked at 66 people with type II diabetes. They were divided into three groups. The placebo group received no cinnamon, the low dose group ingested 120 mg, and the high dose group took 360 mg. After 3 months, the low dose group experienced an average drop of 18.2 mg/l in blood glucose levels. The high dose group experienced an average drop of 29.2 mg/l. There was no change in blood glucose levels in the placebo group. Powdered cinnamon can be taken in small amounts, such as 1/4 to 1/2 a teaspoon in tea or sprinkled on food. You can infuse the bark into various hot dishes, or make a tea from it.
