The present investigation was undertaken to evaluate the anthelmintic activity of Ethanolic and aqueous extract of Vateriaindica (stem bark) using Indian earthworm Phretimaposthuma.Different concentrations viz. (50, 25 and 12.5 mg/ml) of each Ethanolic and aqueous extracts were used for bioassay, involve determination of time of paralysis (TP) and time of death (TD) of the worms. 1% gum acacia in saline solution and Mebendazole (15mg/ml) were used as control and standard respectively. The result of present study indicates that the crude Ethanolic extract of Vateriaindica significantly demonstrated paralysis, and death of worms a concentration 50mg/ml compared to standard reference Mebendozole.
