RESUMO
Objective: To study the effects of potentill on all systems of experimental animals to provide experimental evidence for the comprehensive safety evaluation of potentill.Methods: Mice and rats were given potentill orally to determine the influence on all systems, and the general pharmacological activities of potentill were recorded.Results: The general behavior of mice was normal after the adminisration of potentill , the test samples showed no synergetic hypnotic effect with nembutal at subthreshold dose, and had no influence on the spontaneous activity and body coordination ability of mice (P＞0.05).The test samples showed no obvious influence on the cardiovascular system and respiratory system of rats (P＞0.05).Conclusion: Potentill meets the general requirements of pharmacology at the prescribed dose.
