The invention discloses a puerarin pharmaceutical composition with a brain injury protection effect. The research result displays that puerarin has a brain protection effect on rats with cerebral ischemia-reperfusion injury, a cerebral infarction area can be reduced; if the medicine is administrated together with radix salviae miltiorrhizae terpene ether; the brain protection effect of puerarin isfurther enhanced; a blood-brain barrier model proves that the enhancement effect of the radix salviae miltiorrhizae terpene ether on the brain protection efficacy of the puerarin is related to the enhancement of the brain absorption of the puerarin, so that the radix salviae miltiorrhizae terpene ether and the puerarin can be prepared into the pharmaceutical composition to overcome the defect that the blood-brain barrier hinders the absorption of the puerarin in the prior art.
