The present study was done with the aim to investigate the anthelmintic activity of polyherbal formulation containing herbs Thespesia populnea (bark), Terminalia alata (bark), Clematis triloba (roots) and Ceratophyllum demersum (leaves) using adult earthworm Pheritima posthuma. The aqueous and ethanolic extract of the crude drug of different concentration were tested which involve determination of paralysis time and time to kill the worms. Piperazine citrate was used as standard and it was found that the PHF ethanolic extract activity is higher than PHF aqueous extract.
