According to the European Food Safety Authority (EFSA), Cassia cinnamon, the most common type found in grocery stores, contains high levels of coumarin, a compound that can be toxic to the liver in large amounts. This makes understanding the key differences crucial for anyone asking, "Is it safe to add cinnamon to tea?" in their daily routine.

One teaspoon of common Cassia cinnamon can have between 7 and 18 milligrams of coumarin, a substantial amount that might reach or surpass the safe daily intake limits for some individuals. However, this quantity is almost entirely dependent on the specific cinnamon variety, as coumarin levels vary dramatically between different types.
