Efficacy and Safety of Compound Glycyrrhizin in Patients With Alopecia Areata: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis evaluated the efficacy and safety of compound glycyrrhizin (CG) in treating alopecia areata (AA) by analyzing 23 studies with 2,219 patients. The results showed that CG combined with conventional treatments significantly improved the cure rate and total efficacy rate compared to conventional treatments alone, as well as improved the Severity of Alopecia Tool (SALT) score. Although some patients experienced adverse events such as oedema, elevated blood pressure, and gastrointestinal discomfort, the combination of CG and conventional treatments was deemed effective and safe, promoting hair regrowth with mild adverse effects.
