The aqueous extract of Cinnamomum camphorLeaves was investigated for anthelmintic activity using earthworms(Pheretima posthuma), tapeworms (Raillietina spiralis) and roundworms (Ascaridia galli). Various concentrations (10-70 mg/ml) of plant extract were tested in the bioassay. Piperazine citrate (10 mg/ml) was used as reference standard drug whereas distilled water as control.Determination of paralysis time and death time of the worms were recorded. Extract exhibited significant anthelmintic activity at the concentration of 50 mg/ml. The result shows that aqueous extract possesses vermicidal activity and found to be effective as an anthelmintic. Therefore, the anthelmintic activity of the aqueous extract of Cinnamomum camphorLeaves has been reported. Introduction Infections with helminth are among the most widespread infections in humans and other domestic animals affecting a large number of world population. The majority of these infections due to worms are generally restricted mainly to the tropical regions and the occurance is accelerated due to unhygienic lifestyle and poverty also resulting in the development of symtomps like anaemia, eosinophilia and pneumonia1. Parasitic diseases cause ruthless morbidity affecting principally in population.
