ABSTRACT
Depression is a common mental disorder. It is estimated that by 2020, the global incidence of depression will be about 20%, which will bring huge economic burden to society. The pathogenesis of depression is complicated, the diagnostic method is not objective, and the cure rate is low. Antidepressants are often associated with adverse reactions during treatment, and patient compliance is poor. Therefore, a single component with antidepressant effects in natural medicines or a compound Chinese medicine gradually shows an advantage in the treatment of depression. Berberine (C20H18NO4) is one of the main components of traditional Chinese medicine Coptis. In recent years, a large amount of evidence indicates that berberine has a good antidepressant effect on different animal models of depression, and its mechanism may be related to the regulation of monoamines and metabolism, anti-inflammatory and anti-oxidation in the brain. This article describes the antidepressant effect and mechanism of berberine, and provides a basis for further exploration and research on the antidepressant effect of berberine.
