INTRODUCTION It has been reported that infectious diseases account for one-half of all deaths in the tropical countries (WHO, 1977). As a result, people of all continents have long applied poultice and imbibed infusions of indigenous plants dating back to prehistory for health purposes and is still in use today (Sofowora, 1993; Iwu, et al. 1983). Plant medicine (phytoamedicine) has been used in healthcare delivery in many parts of Africa and the rest of the world (Elujoba, et al., 2005).
