Abstract

Previous studies on the pharmacology of South African medicinal plants in our laboratories and elsewhere have shown that some plants possess therapeutic attributes. One such ethnomedically useful plant is Sutherlandia frutescens R. BR. (family: Fabaceae). S. frutescens is widely used in South African traditional medicine for the management and/or control of a plethora of human ailments. In order to scientifically appraise some of the ethnomedical uses of S. frutescens, the present study was undertaken to investigate the analgesic, antiinflammatory and antidiabetic properties of the plant's shoot aqueous extract in experimental animal models. The analgesic effect of the herb's shoot extract was evaluated using the hot-plate and acetic acid test models of pain in mice, while the antiinflammatory and hypoglycemic effects of the plant's shoot aqueous extract were investigated in rats, using fresh egg albumin-induced pedal (paw) edema, and streptozotocin (STZ)-induced diabetes mellitus. Diclofenac (100 mg/kg) and chlorpropamide (250 mg/kg) were used, respectively, as reference drugs for comparison. S. frutescens shoot aqueous extract (50-800 mg/kg i.p.) produced significant (p < 0.05-0.001) analgesic effects against thermally- and c...Continue Reading
