1.0 Introduction
Trypanosomiasis, a disease of major importance in human and animals has continued to threaten human health and economic development. Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense as the etiological agents of trypanosomiasis affect millions of people in sub-saharan Africa and are responsible for the death of about half a million patients per year. Another name for the human form of the disease is sleeping sickness while that of cattle is nagana. The World Health Organization reported that 70-90% of the world’s population relies on the use of plant extracts or their active constituents. Many plants have therefore become sources of important drugs. There has been several claims by the traditional medical practitioners that Vitex simplicifolia Oliv. cures trypanosomiasis. This informed the reason for investigating the plant.
