Cinnamon Oil: Composition, Properties, and Uses
Introduction
Cinnamon Oil, traditionally known as Oleum Cinnamomi, is a fragrant essential oil obtained mainly from the bark of Cinnamomum zeylanicum through the process of steam distillation. In some cases, the oil may also be extracted from the leaves and roots of the plant.
For centuries, cinnamon oil has been widely used in traditional medicine, perfumery, and aromatic preparations because of its warming, stimulating, and soothing properties.
