Infectious diseases are one of the leading causes of morbidity and mortality in the developing world. In Africa and other developing countries including Ghana it is estimated that 70 to 80% of patients rely on traditional medicine for their health needs, including treatment of infectious diseases. This is because of the high cost of orthodox medicines as well as inadequate healthcare facilities and professionals, while herbal medicines are much more easily available and affordable (sometimes free of charge) from traditional healers. Thus, African folk medicine offers a vast repository of plants and herbal preparations with documented usefulness against infections, many of which still await chemical investigation and possible formulation into suitable dosage forms. Medicinal plants are therefore being investigated for their potential to treat infectious diseases including neglected diseases such as Leishmania major, Onchocerca volvulus, Schistosoma spp. and Onchocerca ochengi. My major interests include:
Search for bioactive compounds from medicinal plants against Leishmania major, O. volvulus, Schistosoma spp. and O. ochengi.

Wound healing activities of some isolated compounds and extracts from medicinal plants

Antibiotic resistance in humans, poultry and other animals

Antimicrobial activities of some Ghanaian medicinal plants
