Pharmacognostic parameters for evaluation of the rhizomes of Curcuma caesia

In ethno medicinal practices, the traditional healers use the genus Curcuma for the treatment of various ailments but Curcuma caesia Roxb. is a very less known and almost untouched drug. The present work attempts to establish the necessary pharmocognostic standards for evaluating the plant material of C. caesia Roxb. Various parameters, such as morphology, microscopy, physicochemical constants, and phytochemical profiles of the entire parts of the plant were studied and the salient diagnostic features are documented. Major chemical constituents, extractive values, physicochemical constants, and other features are also been recorded.
