This study deals with Phytochemical screening and in vitro anti -inflammatory activity of aqueous extract of Cinnamomum verum bark. The plant material was collected and subjected to extraction by distilled water. Further phytochemical test and anti -inflammatory activity of the extract was evaluated. The results showed that The percentage yield of aqueous extract of Cinnamomum verum was found to be 16.12% with dark brown colour. The phytoconstituents like Alkaloids, Saponins, Phenols, Carbohydrates, Flavonoids, Proteins & amino acids, Diterpenes were found to be present. The percentage inhibition for standard drug diclofenac was found to be 313.70% while for aqueous extract of Cinnamomum verum the IC50 value was found to be 268.29%. The results indicate that the aqueous extract of Cinnamomum verum have more potent anti -inflammatory effect than standard drug diclofenac.
