Introduction
Introduction from Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Cinnamomum_aromaticum, retrieved 02/22/2012).
Cinnamomum aromaticum, called cassia or Chinese cinnamon, is an evergreen tree native to southern China, Bangladesh, Uganda, India, and Vietnam. Like its close relative Cinnamomum verum, also known as "Ceylon cinnamon", it is used primarily for its aromatic bark, which is used as a spice. In the United States of America, cassia is often sold under the culinary name of "cinnamon". The buds are also used as a spice, especially in India, and were once used by the ancient Romans.
The tree grows to 10–15 m tall, with greyish bark and hard elongated leaves that are 10–15 cm long and have a decidedly reddish colour when young.
