It grows in low-altitude mountain areas from 400 meters to 1,500 meters above the sea level. Because essential oil from its leaves contains similar ingredients to C. cassia essential oil but of different chemotype, showing valuable potential for further development and application, the oil is of great potential value.Research commissioned by the Forestry and Nature Conservation Agency to academia throughout the years confirmed that the leaves, branches, essential oil and extracts from cinnamaldehyde-type cinnamomum osmophloeum possess many benefits which have prompted the interest of domestic industries. Now, quite a few manufactures have applied these research results and turned the leaves, essential oil and extracts from cinnamomum osmophloeum into products like cinnamon tea bags, cinnamon sugar, cinnamon powder, cinnamon wine, cinnamon vinegar, cinnamon hydrolate, cinnamon shampoo, mosquito repellent, and cinnamon toothpaste. High-value applications such as healthcare products can also be developed in the future.
