The evaluation of the treatment effect of syndrome differentiation restricts the development of traditional Chinese medicine（TCM）. Through analysis

it is believed that the curative effect of syndrome differentiation reflects the comprehensive ability and level of doctors to control intervention measures

and syndrome differentiation has different stages from personal experience to the generation of new interventions. Based on this essence and characteristics

three periods（exploration period

exploration period and empirical promotion period）

six stages（exploration

initial construction

perfect exploration

verification and practice） and progressive mode of gradually mature research elements are constructed. The model can guide researchers to locate their research field

choose research methods according to goals and requirements; improve the scientificity and feasibility of research on syndrome differentiation and treatment

fully reflect the clinical efficacy of syndrome differentiation and treatment; be conductive to promote the optimization of syndrome differentiation and treatment plan

the discovery and consolidation of core prescriptions

to doctors condense

enrich and develop TCM theories from clinical practice

and provide more methodological references for the evaluation of complex interventions.
