This thesis discourse upon blood stagnant in cerebral venation is the pivotal pathogenesis of cerebral ischemia stroke,and discuss once the cerebral ischemia occur,it can derive more phlegms,toxic heat and other pathological outcomes,resulting in inflammatory injury of cerebral ischemia,forming a vicious circle of "inflammation-thrombus",so that aggravating the injury with ischemia and anoxia of never cells,even causing inreversible putrescence of cerebral ischemia.And this condition should be the springs of the development and aggravation of the illness.Therefore,applying promoting blood circulation for removing blood stasis measures can removing blood stasis,eliminating pathogenic wind-fire and cleanning out phlegm,so the pyogenic infections can be dispelled,and the pathological state of inflammation,injury and microcirculation obstacle in the brain can be meliorated.Then,the brain vascula become smooth and the blood supply resume,the symptoms with never functional impairment alleviate or meliorate,thereby,the rate of death and cripple decrease obviously.
