Chinese cinnamon (Cinnamomum cassia) belongs to Lauraceae (the Laurel family). It is a tall evergreen tree originating in southern China, and widely cultivated in China, southern and eastern Asia. This tree grows to 10-15 m in height, with greyish bark. The leaves are ovate-oblong, glossy and with prominent three veins. They have a decidedly reddish color when young. It is one of several species of Cinnamomum used primarily for their aromatic bark, which is used as a spice. Most of the spice sold as cinnamon in the United States, United Kingdom, and India is Chinese cinnamon.
