This prescription can be a representative prescription regulating the function of liver and spleen, praised as "the best prescription for liver diseases". Doctors in later ages created many famous modified prescriptions on this basis. Its clinical application is becoming more extensive gradually.Traditional Chinese Medicine has a view called treating different diseases with same method. The same method can be adopted to treat different diseases because these diseases may have the same pathogenesis in their development process. Chinese traditional treatment pays more attention to the difference in pathogenesis instead of disease. Whether different diseases can be treated with the same method depends on whether there is common pathogenesis among different diseases, independent of etiology and syndrome. Only when the pathogenesis is the same, can the disease be treated with the same method.

Therefore, people should first get the concept of Xiao Yao San syndrome clear, and then correctly use Xiao Yao San to treat diseases.
