The current study was designed to explore the antiemetic effect of the methanolic extract of Tithonia diversifolia (Hemsl.) A. Gray., leaves using chick emesis model to validate their folk use in G.I. disorders. Emesis was induced by the oral administration of copper sulfate 50mg/kg body weight to male chicks of four days of age. The antiemetic activity was determined by calculating the mean decrease in the number of retching compared to the control. Tithonia diversifolia leaves extract (150 mg/kg orally) showed a significant (p <0.05) antiemetic effect and was compared with the reference drug chlorpromazine.
