Cassia comes from the bark of a tropical evergreen that is related to the bay laurel tree. It is native to Indonesia and, according to some sources, also to northeastern India. The Cinnamomum family includes dozens of members; C. zeylanicum is considered “true cinnamon” (see Cinnamon). Like cinnamon, cassia is an ancient spice, and its history dates back centuries.

The major producers of cassia today are Indonesia, China, and Vietnam; it is cultivated in India, too, where the leaves of the tree are also used as a spice
