Abstract

ObjectiveTo carry out an exhaustive study with a view to substantiate the therapeutic potential of the plant in terms of its anthelmintic activity against Pheretima posthuma using mebendazole as a reference standard.MethodsForty five worms were collected and were divided into nine groups and were washed in normal saline before they were released into 10 mL of respective drug solutions using distilled water as vehicle. Different concentrations (25 mg/mL, 50 mg/mL and 100 mg/mL) of the test (MEHI and AEHI) and standard solution were prepared before the commencement of the experiment. Time for paralysis and time for death were recorded for each group.ResultsCrude methanolic extract with concentrations of 25 mg/mL, 50 mg/mL, 100 mg/mL produced dose-dependent paralysis. Time of paralysis and death increased with concentration of 25 mg/mL, 50 mg/mL as compared with that of standard drug mebendazole. Methanolic extract of Heliotropium indicum Linn. (H. indicum) gave shorter paralysis and death time at 100 mg/mL as compared to aqueous extract H. indicum Linn. Results are expressed as mean±SEM (P<0.05) of 5 worms in each group.ConclusionsFrom the investigation, conclusion can be drawn that the methanolic extract of H. indicum (Boraginaceae) showed better activity than aqueous extract of the same to treat intestinal worm infections. In comparison with the standard drug mebendazole, methanolic extract of H. indicum showed significant anthelmintic efficacy.
