This study investigates the anthelmintic activity of methanolic extracts from roots of Costus igneus (insulin plant) against the Indian earthworm Pheretima posthuma. Using varying concentrations (10 mg/ml to 40 mg/ml) of the extract, the evaluation focused on paralysis and death times of the worms. The results indicate a dose-dependent effect, with the 40 mg/ml concentration demonstrating significant efficacy by causing paralysis in 22 seconds and death in 29 seconds. These findings affirm the potential use of Costus igneus roots as a natural anthelmintic agent.
