The blood hemostatic activity of the Tibetan medicinal herb Lamiophlomis rotata was evaluated in BALB/c mice and Wistar rats. L. rotata aqueous extract (LRAE) was given to mice at concentrations of 0.5, 1.0, 2.0 g/kg body weight and 0.75, 1.5, 3.0 g/kg to rats. The hemostatic activity of LRAE was estimated by changes in bleeding time (BT), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB). ⋯ On the other hand, LRAE showed some effects in improving the liver function and reducing blood lipids by decreasing the levels of AST, ALT, Chol and LDL-C. All these changes had a significant dose-effect and time-effect relationship. These results confirm the hemostatic and thromboplastic effects of L. rotata and these effects might be implemented by improving the synthetic function of the liver.
