| Abstract | Eupatorium adenophorum Spreng belonging to the family Astercaceae is an annual herb. It grows up to one meter high,
bears small white-colored flowers. Even though this plant has gained scientific importance recently, there is a need
for the pharmacognostic standardization. Hence, in the present work the leaf and petiol part of the plant were subjected
to various microscopical and physical evaluations. In the microscopical studies, the different cell structures and
arrangements were studied and in physical evaluation the ash values and extractive values were studied. The various
pharmacognostical constants were obtained which could help in the development of a suitable monograph for the plant.
