Comment by tonytran2015: This blogs shows why Ceylon Cinnamon is preferable to all other types of Cinnamon for people who want to use it to treat diabetes.
The biggest advantage of Ceylon Cinnamon (also known as Mexican Cinnamon) is ultra-low Coumarin levels. Coumarin in high doses causes liver failure, so for people who take Cinnamon on a daily basis, Ceylon Cinnamon is the preferred choice.
