“Kien nao dan” (KND) tablet is composed of 13 traditional medicines that may has preventive and effective treatment of cerebral ischemia. However, there are no scientific reports of its toxicological properties which guarantee of the safety its usage treatment. Therefore, the aim of this study was to investigate the sub-chronic toxicity of KND tablet on rats through oral administration. The sub-chronic toxicity was evaluated by the recommendation of WHO in Wistar rats at doses of 0.72 g/kg/day (equal to recommended human dose) and 2.16 g/kg/day (3 times as high as recommended human dose) for 8 consecutive weeks. In the evaluation of sub-chronic toxicity, there were no behavioral and physiological changes or signs of toxicity. The result of the hematological and biological parameters after administration of KND tablets showed no change. The histopathologic analysis of livers and kidneys indicated that no significant differences were observed between the exposed and unexposed rat groups. In conclusion, “Kien nao dan” tablets did not produce sub-chronic toxicity in Wistar rats.
