Cinnamon powder comes from the bark of tropical, evergreen trees. In order to harvest cinnamon, it's peeled off of the inside of the bark of the tree. You've probably sprinkled cinnamon on foods like toast, rolls, and desserts. But cinnamon has uses other than for topping sweets, including improving your health. Cinnamon is also a common ingredient in many Indian curries because of its delicate fragrance and refined taste.
