Introduction
Cinnamomum zeylanicum, commonly known as True Cinnamon or Ceylon Cinnamon, is one of the most valued aromatic plants in the world. It is widely used as a spice, flavoring agent, and medicinal herb in traditional systems of medicine such as Ayurveda and Unani medicine.
The tree is famous for its fragrant inner bark, which is dried and rolled into the well-known cinnamon sticks used in cooking and herbal remedies. Due to its pleasant aroma and therapeutic properties, cinnamon has remained an important medicinal and culinary ingredient for centuries.
