Hemosiderin has no role in preventing cerebral thrombosis, so for patients with cerebral thrombosis, it is recommended to go to regular hospitals for standardized and scientific treatment. From the international and domestic scientific verification, there are only a very limited number of medicines with the function of preventing cerebral thrombosis. Aspirin or clopidogrel combined with atorvastatin is an effective medicine for preventing cerebral thrombosis, which has been used all over the world with a large amount of scientific evidence. Therefore, patients with cerebral thrombosis, no matter which hospital they go to and which doctor they see for treatment, will almost invariably be recommended to use these drugs. As a traditional Chinese medicine that activates blood circulation and removes blood stasis, Xuesetong has been used as an adjunctive medicine in the treatment of cerebral thrombosis, but it does not have the effect of preventing the recurrence of cerebral thrombosis.
