Anthelminthic Activity of Withania somnifera. L. Dunal Water Extract in Sheep

Abstract

The anthelminthic activity of Withania somnifera, L. Dunal a Maasai traditional anthelminthic was studied in sheep. The McMaster egg count technique and coproculture was used to evaluate worm infestation and the effect of the water extract of the medicinal plant. The water extract was prepared in accordance with the Maasai traditional method. The results showed that the reduction in the egg per gram count in sheep treated with Withania somnifera water extract is comparable to that of Lepoxy (a levamisole-based anthelminthic) and was significant (p<0.05) when compared to the control non-treated animals. It is concluded that Withania somnifera has anthelminthic activity and that the effect against tapeworms (Monieza benedeni and M. expansa) is more predominant.
