I recently learned that a lot of what is labeled as "cinnamon" in this country isn't actually. It's a similar tasting bark called cassia. It MAY or may not have the same properties as real cinnamon. To be sure I had REAL cinnamon, I'd trust a label that says "real cinnamon bark" on the ingredients list on back OR I'd buy actual sticks of cinnamon, which are distinguished by the way they rolled up. they'll be rolled from both sides to meet in the middle, not in a single spiral roll.
