Cinnamon

The cinnamon tree grows in moist well-drained soils and rarely reaches more than 15 metres (49 feet) in height. The thick simple leaves have smooth margins and are usually oval; the veins are roughly parallel to each other. Young leaves are red and mature to a deep green. The small bisexual flowers are greenish to yellow and are borne in clusters. The fruit is a dark drupe.
Cinnamon contains 0.5 to 1 percent essential oil, the principal component of which is cinnamic aldehyde.
