The present study was envisaged to evaluate the efficacy of ethno-medicinal plant aqueous extracts such as Allium sativum, Lawsonia inermis, and Opuntia ficus indica in vitro in comparison with the chemotherapeutic agent, Oxyclozanide on Fasciola gigantica adults. The efficacy was evaluated by gross visual motility and mortality of F. gigantica with score index, light microscopic examination of carmine stained flukes and histopathology of treated flukes. Based on the in vitro trials conducted using above plant extracts at 1 percent, 2.5 percent and 5 percent concentration, the extracts of O. ficus indica showed flukicidal effect at 2.5 and 5% concentration. However A. sativum and L. inermis were effective at 5% concentration only. The study indicated the potential for developing herbal-based anthelmintics to control F. gigantica in livestock.
