Composition of Cinnamon Leaf Essential Oil and Its Benefits

People in Indonesia have long recognized Cinnamomum burmanii, commonly known as cinnamon, as a medicinal plant, flavor enhancer, and fragrance ingredient. One of the commercial forms of cinnamon is the essential oil. The parts (aside from the cinnamon bark) that contain essential oil are leaves in cinnamon plants.
The bark contains approximately 1-2% essential oil, with cinnamaldehyde as the main constituent (70-80%), while the leaves contain around 0.5-0.7% essential oil, primarily composed of eugenol (70-95%) and cinnamyl acetate (3-4%).
Research conducted in Indonesia has demonstrated the significant role of cinnamon leaf oil as a mosquito repellent and its efficacy against dengue fever mosquitoes. This effect is attributed to the compounds found in the cinnamon leaf essential oil, namely cinnamyl acetate and eugenol. Furthermore, eugenol in cinnamon leaf oil has been found to have Monoamine Oxidase Inhibitors (MAOI) effects, acting as an antidepressant, as suggested by a study conducted in Indonesia.
