Objective: To study the acute and subacute toxicities of sappan wood extract in rats. Material and Method: For studying acute toxicity, a single oral dose of 5,000 mg/kg of sappan wood was administered to rats. Subacute toxicity was studied by the daily oral administration of the extract at the doses of 250, 500 and 1,000 mg/kg body weight for consecutive 30 days. Results: The extract of sappan wood (5,000 mg/kg) showed no toxicity in terms of general behavior change, mortality, or change in gross appearance of internal organs. Subacute toxicity study showed no abnormalities in treatment groups as compared to the controls. Body and organ weights, hematological, blood chemical, necropsy, and histopathological parameter of all groups were similar. Conclusion: Sappan wood extract did not produce any acute or subacute toxicity in both female and male rats.Mahidol UniversityMedicineArticleSCOPUS
