Application of "Si Ni He Wei Tang" Based on "Internal Regulation of Qi" by Yang Zhen

Si Ni San is a widely known formula created by Zhang Zhongjing in the Eastern Han Dynasty and described in the Treatise on Typhoid Fever, which consists of four herbs: Bupleurum (Bupleurum chinense), Bitter Orange ( Aurantii Fructus Immaturus), Peony Root (Paeoniae Radix Alba), and Licorice. Yang emphasizes the changes of qi in the human body and often uses Si Ni San to treat miscellaneous internal diseases. As modern diseases are becoming more and more complicated, the efficacy of Si-Reversing-San alone is weak. Professor Yang Zhen used Si-Reversing-San as the base formula and combined it with He Wei Tang composed of Citron Fruit (Citri Sarcodactylis Fructus), Cyperus Rhizome (Cyperi Rhizoma), Finger Citron (Citri Sarcodactylis Fructus), Forsythia (Forsythiae Fructus), Indian Trumpet Flower (Oroxylum Indicum), and Bitter Orange Peel (Aurantii Fructus), and his own Si Ni He Wei Tang has a remarkable efficacy in the treatment of modern miscellaneous diseases.翻译搜索复制
