Microscopic Characteristics

Cassia (bark) (Cinnamomum aromaticum) (Cinnamomum cassia auct.)Rather short, thick walled bast cells sclerenchyma with cell walls unequally thickened parenchyma cells with compound starch granules; cells with numerous small prismatic crystals; large resin bearing cells; cells of outer bark suberized and with reddish brown contents. Cassia bark contains relatively more starch than do the other varieties of cinnamon barks and relatively less bast tissue.
