Ceylon cinnamon sticks are a type of cinnamon that comes from the bark of Cinnamomum verum, a small evergreen tree native to Sri Lanka and Southeast Asia.
 
Ceylon cinnamon is also known as "true" or "real" cinnamon, because it has a more delicate and sweet flavor than the more common cassia cinnamon. Ceylon cinnamon sticks are often used to add aroma and warmth to drinks, desserts, curries, and other dishes.
 
Ceylon cinnamon sticks also have some health benefits, such as reducing inflammation, lowering cholesterol levels, and improving insulin response. Ceylon cinnamon sticks are rich in antioxidants, beta-carotene, and manganese, which help protect the body from free radicals and support various functions. Ceylon cinnamon sticks can be ground into powder or used whole in recipes that require long simmering or steeping.
