ABSTRACT
Objective To study the blood_flow_activating and blood_stasis_removi ng actions of Qushang Tablet (QT) and its safety. Methods Thirty rats were randomly allocated to Group A (normal control), Group B (models control) and G r oup C (treated with QT). Rat models with traumatic blood_stasis syndrome were in duc ed by the bruise of falling iron hammer. Effects of QT on blood rheology of rat model were studied. Acute and chronic toxic effect of QT was also studied. Res ults QT had obvious effect on blood rheology of rat model and could improve th e concentration, viscosity, aggregation and coagulability of blood. No acute and chronic toxic effect of QT was found. Conclusion QT exerts obvious blood_fl ow_activating and blood_stasis_removing actions and is safe to be applied in cli nic.
