Just make sure to choose real cinnamon (also known as Ceylon cinnamon), not cassia cinnamon (also known as Chinese cinnamon). In the United States, if it doesn’t specify Ceylon on the label, it’s probably cassia, which, as I described in How Not to Die, has too much coumarin for comfort. A single daily teaspoon of cassia cinnamon could exceed the safety limit for liver toxicity risk in an adult, and even a quarter teaspoon may be too much for a small child.3581 So make sure it says Ceylon on the label, and then sprinkle to your heart’s desire.
