Current Research Progress on the Preprotection of Astragaloside on Ischemic Stroke and Its Mechanism

As a neurological disease with high morbidity, mortality and disability, ischemic stroke poses a serious threat to human health, and effective preventive measures can largely delay its occurrence and development. Astragaloside, as the main active ingredient of Astragalus, has a variety of immunomodulatory effects including anti-oxidative stress and anti-inflammation. However, there is no summary report on the pharmacodynamic mechanism of astragaloside on the pre-pathogenesis of stroke. Several studies have shown that AS-IV can improve coagulation function, smooth muscle cells, and vascular dysfunction. Therefore, this review focuses on the mechanism of action and constitutive relationship of astragaloside on ischemic stroke mainly based on the perspective of pre-protection prior to the occurrence of cerebral ischemia, aiming to summarize the progress of the research on astragaloside in the pre-pathogenesis of stroke and to explore the direction of its potential application.
