In Sri Lanka thishas been applied for hundreds of years asunorthodox medicine. This study was focused to assess the possible toxicity of the water extracts of M. pinnata (MPW) in healthy and diabetic Wistar rats. Acute and chronic administration of MPW produced no neither mortality nor changes in general behaviors compared with Control groups. The results showed no statistically significant changes in hematological and biochemical values of Test groups compared to the control groups of both healthy and diabetic animals.
