Cinnamomum cassia, commonly known as Cassia cinnamon or Chinese cinnamon, is a spice obtained from the bark of an evergreen tree belonging to the Lauraceae family. Native to China and widely cultivated across Southeast Asia, Cassia cinnamon has been extensively used in traditional medicine for its potent antioxidant, anti-inflammatory, antimicrobial, and blood sugar-regulating effects (Gruenwald et al., 2010).
The spice is typically harvested by peeling the bark during the rainy season, which is then dried and rolled into characteristic cinnamon sticks or ground into powder.
