Methods: Thirty-six papers were collected from searches of CNKI, Wanfang, PubMed, and other databases and then they were summarized. Results: Researchers have carried out widespread and various pharmacological studies of Sowthistle-leaf Ixeris seedling, and have pursued different research directions on its etiology and pathogenesis, syndrome differentiation and treatment methods for acute cerebral infarction (ischemic stroke). With the development of Chinese medicine, its safety and non-toxic side effects have been recognized by the majority of scholars. The research results have contributed significantly to the treatment of acute cerebral infarction by Sowthistle-leaf Ixeris seedling. Conclusion: Sowthistle-leaf Ixeris seedling has extensive medicinal value and unique advantages in the treatment of acute cerebral infarction, especially in expanding brain vessels, increasing blood flow, reducing thrombosis, protecting brain cells, improving neurological impairment, and it has no toxic side effects.展开更多
