Background: Cinnamomum verum (true cinnamon or Tejpatra) is a well-known spice with immense medicinal properties. Its adulteration with leaf and bark of other species belonging to genus Cinnamomum is found to be a common practice in India. Aims: Cinnamomum sulphuratum is used as a substitute of C. verum owing to its apparent macroscopic similarities. Materials and Methods: Fresh leaves of C. verum and C. sulphuratum growing in South India were collected and studied to establish their macro–microscopic identity with pharmacognostical perspective. Results: Detailed microscopic evaluation by transverse section, maceration, and powder microscopy was conducted to delineate the two species. Detailed macroscopic identification served the purpose of identification of the entire drug on the spot, and microscopy has helped in the identification of fragmented and powdered form of the drugs. Conclusion: Further chemical and biological studies may be necessary to confirm whether these leaves can be used as a substitute or adulterant for other species Cinnamon.
