[Research progress on mechanisms of ligustilide in treatment of nervous system diseases].

Ligustilide is the main active component of the volatile oil from Angelica sinensis and Ligusticum chuanxiong in the Umbelliferae family. It is a phthalein compound with anti-inflammatory, analgesic, antioxidant, anti-tumor, anti-atherosclerosis, neuroprotective, and other pharmacological effects. It can improve the permeability of the blood-brain barrier and has important potential in the treatment of neurodegenerative diseases and other nervous system diseases, such as Alzheimer's disease, ischemic stroke, Parkinson's disease, vascular dementia, and depression. Therefore, the mechanism of ligustilide in the treatment of nervous system diseases was summarized to provide a reference for drug development and clinical application.
