  • Professor Adaobi C. Ezike, , B. Pharm, M. Pharm, PhD

The main thrust of her research has been the elucidation of the pharmacological actions of medicinal plants. Consequently, her research team has established the

pharmacological basis for the use of different medicinal plants in the ethnomedicinal

management of diseases ranging from asthma, diabetes, ulcer, wounds to inflammatory

disorders. Her research strategy is rooted in the separation of bioactive constituents of

medicinal plants, with the ultimate aim of isolating bioactive compounds.
