[Viewpoint regarding "concise" of "classical formula" from case].

"Classical formula" are praised for their exact clinical efficacy,but many scholars of " classical formula" still remain in the simple symptoms and the superficial form of formula matching,failing to explore the connotation of " classical formula" in a subtle and in-depth way. The clinical curative effect and charm of " classical formula" mainly lie in " concise". " Concise" can be divided into many aspects,including " correspondence of formula and syndrome" infers pointing accuracy, " Classic formula" infers structure refining,and " pattern differentiation" infers process elaborating,ect. " Correspondence of formula and syndrome" requires doctors to take into account multiple factors such as physical characteristics,symptom features,diet taste and emotional preference of patients,so as to grasp its essence more accurately. " Classic formula" implies paying special attention to its composition and various methods of addition and subtraction. Not following Zhang Zhongjing's method and gilding the lily will affect the clinical efficacy. " Pattern differentiation" indicates doctors should separate Yin and Yang,examine syndrome features and distinguish the categories following the method of traditional Chinese medicine with comprehensive observation and comprehensive consideration in-depth so as to accurately select the appropriate prescription and improve the clinical efficacy.
