Cinnamon Leaf Oil Ceylon is derived from the dried leaves of the Cinnamomum zeylanicum tree, also known as “true cinnamon” or “Ceylon cinnamon.” The tree is mainly cultivated in Sri Lanka, where local growers employ unique farming techniques that maximize the number of accessible leaves produced by each tree. The aroma and flavor of cinnamon leaf oil is mainly characterized by its high eugenol content. This imparts a sharp, fresh, spicy aroma that radiates warmth. In fragrance, cinnamon leaf oil can instantly add a warm-spicy texture to woody and sweet perfumes. In flavor, this warmth is often used to contrast the intensity of fruit, chocolate, or liquor profiles.
