Stroke characterized by acute onset，severe illness，rapid changes，and diverse symptoms is caused by a combination of diverse factors.According to the theory of traditional Chinese medicine，this disease is caused by brain collateral injury by toxin or failure of nourishment in the brain and marrow because of qi deficiency.Accordingly，the treatment methods include eliminating pathogen and reinforcing healthy qi.The key to improving clinical efficacy lies in how to properly eliminate pathogen and reinforce healthy qi in the treatment of stroke.At the beginning of a stroke，phlegm and stasis generate toxins，causing damage to the brain collaterals and exuberance of toxin and pathogen.Therefore，it is necessary to first eliminate the pathogen，detoxify，and dredge the collaterals.Considering different syndrome elements，the method of clearing heat to resolve phlegm or resolving phlegm to relax bowls can be adopted.Moreover，we suggest the early application of tonifying qi and reinforcing healthy qi to eliminate pathogen.Since the onset of stroke is a sign of healthy qi deficiency，the treatment should first replenish qi and reinforce healthy qi，and then eliminate pathogen.After thrombolysis，the consumption of blood and qi results in qi deficiency and collateral obstruction by stasis and sometimes bleeding caused by the failure of qi to control blood due to qi deficiency.Accordingly，the treatment should replenish qi and resolve stasis to dredge collaterals and tonify qi to control blood and protect collaterals.In the recovery phase，kidney deficiency caused by collateral and marrow injury should be treated by tonifying kidney，nourishing marrow，and protecting the brain，which can alleviate the neurological dysfunction after stroke.
