✵In TCM, syndrome differentiation is the process of an overall analysis of data to determine the location, cause, and nature of a syndrome and achieve a diagnosis of a syndrome or pattern.
The following important aspects of TCM syndrome differentiation are introduced: Eight-principle syndrome differentiation, Six-meridian syndrome differentiation, Defense-Qi-Nutrient-Blood Syndrome Differentiation, Triple-Energizer syndrome differentiation, Qi-blood syndrome differentiation, Body-fluid syndrome differentiation, Disease-cause syndrome differentiation, Zang-Fu viscera syndrome differentiation.
Eight-principle syndrome differentiation, also known as eight-principle pattern identification, is the process of diagnosing a syndrome (or pattern) by analyzing the patient's condition according to the eight principles. This involves differentiating the location of a disease between exterior and interior, distinguishing the nature of a disease between cold and heat, identifying the patient's condition as deficiency or excess, and generalizing the syndrome or pattern as yin or yang.
Six-meridian syndrome differentiation
Six-meridian syndrome differentiation, also known as six-meridian pattern identification, involves the differentiation of syndromes (or identification of patterns) according to the theory of the six meridians. This method is applied to the diagnosis of acute febrile disease at different stages, but is also useful for the syndrome differentiation (or identification of patterns) of other diseases.
The Defense-Qi-Nutrient-Blood Syndrome Differentiation, also known as Four-Aspect Pattern Identification, is a method of syndrome differentiation or pattern identification of epidemic febrile diseases according to the theory of defense, Qi, nutrient, and blood. These elements indicate the stages of the disease's progression and the corresponding pathological changes.
Triple-Energizer syndrome differentiation
The Triple-Energizer Syndrome Differentiation, also known as Triple-Energizer Pattern Identification, is a method of syndrome differentiation or pattern identification that is based on the theory of the triple energizer.
Qi-blood syndrome differentiation
Qi-blood syndrome differentiation, also known as Qi-Blood pattern identification, involves identifying the differentiation of syndromes or identification of patterns based on the state of Qi and blood.
Body-fluid syndromes differentiation
Body-fluid syndromes differentiation, also known as body-fluid pattern identification, involves identifying the differentiation of syndromes or identification of patterns based on the condition of body fluids.
Disease-cause syndrome differentiation
Disease-cause syndrome differentiation, which is also known as disease-cause pattern identification, involves analyzing and differentiating pathological conditions that can be attributed to different types of causal factors in order to make a diagnosis.
Zang-Fu viscera syndrome differentiation
Zang-Fu viscera syndrome differentiation, also known as viscera pattern identification, involves identifying and differentiating syndromes or patterns based on the pathological changes of the Zang-Fu viscera.

Zang-Fu viscera syndrome differentiation, also known as viscera pattern identification, involves identifying and differentiating syndromes or patterns based on the pathological changes of the Zang-Fu viscera.
