| Summary: | Diabetes is a serious condition that affects all the body’s systems including kidneys, heart, eyes and limbs. This alone makes type II diabetes a life threatening disease; an expensive disease and economic burden that many individuals struggle to cope with.The rapid growth type II diabetes in South Africa is associated with the change of life style, and environmental factors brought by westernized way of life living in rural areas. Despite the technical advances in diagnosis and therapy of diabetes many people still use alternative forms of therapy due to the cost, traditional reasons and religion. Some of the people use the conventional medication together with the alternative therapy without informing their doctor and knowing the pathological changes. The aim of the study was to investigate pathological changes in male Wistar rats after co-treatment of type II diabetes with metformin and Sutherlandia frutescens and the possible synergistic and antagonistic effects. The thirty five rats were divided into five groups, seven in each group. There were two control groups and three test groups. Only the first control group was on a low fat diet (normal rat pellets) and second control group and test groups were on a high fat diet which induces obesity, insulin resistance and leads a typical prediabetic state for 12 weeks (Buettner et al., 2006). After 11.5 weeks medication was administered by oral gavaging to the test groups for 4 weeks and control groups received water. Blood was collected for determination of glucose, insulin, lipid profile and the concentrations of the liver enzymes. Pancreas, liver and kidney tissue were removed and used for histology. Urine was collected from the bladder for creatinine analyses. The plant + metformin group co-treatment was better in managing hyperglycemia, liver damages were minimal and also weight control was better when compared to metformin alone.
