Cinnamomum cassia Identity & Plant Part
The botanical entity is Cinnamomum cassia, also catalogued as Cinnamomum aromaticum Nees, an evergreen tree of the laurel family, Lauraceae. The part used is the dried bark. Leaves, buds and twigs are not added to this cinnamon bark extract.
Ceylon cinnamon, Cinnamomum verum, comes from the thin inner bark of another species, and a specification that says only “cinnamon” does not tell a buyer which tree is meant. Cassia bark is thicker and rolls as a single layer, while Ceylon quills are fine and wound in many layers. Cassia bark carries tannin-type polyphenols, a volatile aldehyde fraction and coumarin. After harvest the bark is dried and cut before it goes to the extraction vessel, so the powder reflects the bark layer only.
