The snail Lymnea acuminata is considered to be intermediate hosts because humans harbour the sexual stages of the parasites and the snails harbour the asexual stages. Herbs are believed to be safer than the synthetic drugs for the control of snails. Alcoholic extracts of Capparis decidua flowers have been evaluated for their lethal effect against L. acuminata and their cercarial larvae. 1%, 2%, 5% concentration of alcoholic flower extract of Capparis were not effective for cercaria after 9 hrs of treatment. 100% mortality was not observed in echinostome and furcocerous even in 24 hrs. But surprisingly after 17 hrs 100% mortality was observed in 5% concentration for xiphdio.
