My main interest include bioprospecting of medicinal plants. In particular research involves with exploring the antituberculosis natural product leads from medicinal plants, susceptibility studies of other bacteria to medicinal plants, cytotoxicity of plant extracts/compounds, anticancer activity, antityrosinase (skin pigmentation), anti-acne activity of medicinal plants, isolation and purification of bioactive principles from plants. Scientific exploration integrates the basic and applied Sciences.  Research is being conducted in collaboration with scientistis from other fields and aim is to obtain valuable pharmaceutical and cosmeceutical products from medicinal plants.

I have been placed in the Essential Science Indicators list of the top 1% of publication outputs (citations) in the discipline PHARMACOLOGY and TOXICOLOGY. I have made a significant contribution to the field of Medicinal Plant science. Several medicinal plants with valuable biological activities have been discovered which led to several patents. I have obtained several international patents including 3 US patents, 4 PCT-patents, 8 South African patents, co-authored about 130 research articles in peer reviewed journals and ten book chapters. A book on medicinal plants has recently been published by Elsevier edited by myself.
