Abstract: Intestinal worms affect a host of individuals resulting in malnutrition, stunted growth, intellectual retardation and cognitive deficits. The aim of this study is to investigate the antihelminthic activity of Alstonia boonei De Wild (Apocynaceae) and Vernonia amygdalina (Asteraceae) using earth-worms (Lumbricus terretris). The worms were directly exposed to 50, 100, and 200 mg/ml of aque-ous and ethanolic bark extracts of Alstonia boonei and leaf extract of Vernonia amygdalina and piperazine citrate in a petri dish and in an organ bath. The control group was exposed to distilled water. The time of paralysis and death were determined within a period of 6 h in the petri dish method whiles spontaneous movements of the worms before and after drug administration were recorded on a slow moving kymograph drum in the organ bath method. All doses of the aqueous and ethanolic extracts significantly (P ≤ 0.001) reduced the time of paralysis and time of death compared to the vehicle treated group. The time of paralysis and time of death in the tissue bath method corresponded to that obtained by direct exposure. The extracts exhibited anthelmintic ac-tivity and thus could be an inexpensive and readily available source of anthelmintic treatment
