Schizophrenia is a common disease in psychiatric clinics. TCM treatment has its own advantages and characteristics. Syndrome differentiation and treatment is the core of TCM

while syndromes are the core of syndrome differentiation and treatment. At present

there has still been a lack of unified criteria for this syndrome. Therefore

on the basis of ancient and modern literature research

clinical epidemiological investigations and Delphi method research

the Professional Committee of Mental Illness of the Chinese Society of Integrated Chinese and Western Medicine were summoned three times to discuss the TCM syndrome classification and the syndrome-symptoms of schizophrenia. Finally

the expert consensus standard of TCM syndrome differentiation and classification of schizophrenia was determined. TCM syndromes of schizophrenia were divided into 5 types according to the consensus. Each syndrome has to meet 5 symptoms of the main symptoms plus 6 symptoms of sub-symptoms before the diagnosis can be made. At the same time

relevant symptoms which were of four diagnosis information can be quantified by experts

so that the research work can be unified and quantified

especially in scoring the curative effect of TCM syndromes in clinical research.
