REVIEW OF LITERATURE
The increasing cases of antimicrobial drug resistance are a serious global problem that has prompted the search for new organic molecules with antimicrobial properties and potentials to serve as sources of raw material for the synthesis of new drugs. Of interest are the over 65,000 flowering plants with medicinal properties, that have remained largely untapped in Africa; though the antimicrobial properties of some of them have been identified and documented, while the active ingredients in some others have been isolated, tested and documented. Geographically, the Nigerian climate favors a great array of these medicinal plant species, especially those with antimicrobial properties, and taken advantage of that, Nigerian traditional herbal practitioners have over the years, used them to prepare a variety of herbal therapies for various kinds of ailments including gonorrhea, sore throat and skin infections; even with their little scientific knowledge and this is typically the scenario before the introduction of orthodox medicines into Africa (Uhunmwangho et al., 2014; Amalu et al., 2014).
