What food comes from bark?

Cinnamon is a well-known spice that comes from the inner bark of trees belonging to the genus Cinnamomum. The bark is harvested, dried, and rolled into the familiar quills or ground into a powder for culinary use. Another example is the spice known as sassafras, which is derived from the bark of the sassafras tree and is used in flavoring.
