In this paper,the publication of osthole in protecting brain ischemia were retrieved and summarized. Our analysis found that osthole can not only decrease the cerebral ischemia reperfusion injury by inhibiting the inflammation reaction and lowering cerebral edema,but also increase the activity of antioxidant enzymes in the ischemic tissue of the brain, scavenge oxygen free radicals and reduce ischemia reperfusion injury caused by free radicals. Furthermore,osthole also exhibited a good anticoagulant effect. So the possible mechanisms of the protective role of osthole were reviewed from anti-inflammatory,anti-oxidation, anti-coagulant,anti-apoptotic and other aspects,in order to provide support for the further pharmacological studies of osthole in brain cerebral ischemia.
