Introduction of Eight-principle syndrome differentiation.

 Introduction of Eight-principle syndrome differentiation Introduction: The eight-principle syndrome differentiation, also known as eight-principle pattern identification, is the the process of diagnosis a syndrome(or pattern) by analyzing the patient's condition according to the eight principles. i.e., 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.

 Yin and Yang ✵Yin and Yang: two basic principles for the categorization of syndromes or patterns, including the categorization of the remaining principles, e.g., interior, cold, and deficiency pertaining to yin, and exterior, heat, and excess pertaining to yang.

 ✦Yin syndrome:  a collective term for interior, cold and deficiency syndromes with inhibitory, hypofunctional, quiescent or dimmed manifestations, or inward and downward symptoms, as well as diseases caused by pathogenic factors of yin nature.

 ✧Yang syndrome:  a collective term for the exterior, heat and excess syndromes with excitatory, hyperfunctional, restless or bright caused by pathogenic factors of yang nature.

 ✵Exterior and Interior:  parts of the body, the exterior referring to the skin and body hair, subcutaneous tissues, muscles, and superficial meridians, and the interior referring to internal viscera and bone marrow. An exogenous affliction only involving the exterior is usually milder than that penetrating into the interior.

 ✦Exterior syndrome:  a general term for syndromes that occur chiefly at the early stage of exogenous afflictions or acute infectious diseases invading the human body through the skin surface or respiratory tract and affecting the exterior part of the body.

 ✧Interior syndrome:  a general term for syndromes that indicate the existence of the disease in the zang-fu viscera, Qi and blood, or bone marrow.

 ✵Cold and Heat:  a pair of principles for differentiating the nature of disease.

 ✦Cold syndrome:  a general term for syndromes caused either by exogenous cold factors or by insufficient yang within the body.

 ✧Heat syndrome:  a general term for syndromes resulted either from yang prevalence or from yin deficiency.

 ✵Deficiency or Excess:  is also known as insufficiency or excessiveness, a pair of principles for determining the condition of the body resistance to pathogenic factors. Deficiency denotes insufficiency of normal Qi, while excess indicates the presence of excessive pathogenic factors with intense body reaction or the accumulation of pathological products due to dysfunction of the internal viscera.

 ✦Deficiency syndrome:  a general term for syndromes caused by insufficiency of normal Qi(including yang Qi, yin fluid, essence, blood, nutrients, and defensive Qi).

 ✧Excess syndrome:  a general term for syndromes caused by exogenous pathogenic factors or by accumulated pathological products due to dysfunction of internal viscera, such as phlegm, retained fluid, stagnant blood, and undigested blood.

 ✦Exterior cold syndrome:  a type of exterior syndrome in which the external part of the body is attacked by exogenous cold or wind, manifested by chills or aversion to cold or wind, headache, general aching or joint pains, thin and white tongue coating, and floating and tense pulse.

 ✧Exterior heat syndrome:  a type of exterior syndrome in which the external part of the body is attacked by exogenous wind-heat, manifested by mild aversion to wind, moderate fever, headache, slight thirst, thin white or thin yellowish tongue coating or red tip of the tongue, and floating rapid pulse.

 ✦Exterior deficiency syndrome:  a type of exterior syndrome resulted from lowered superficial defense Qi, and manifested by spontaneous sweating, intolerance of wind, and floating feeble pulse.

 ✧Exterior excess syndrome:  an exterior syndrome with the forceful or light floating pulse and no sweating, showing the external part of the body being attacked by exogenous pathogens, yet the patient's defense Qi is not damaged.

 ✦Interior cold syndrome:  a type of interior syndrome caused either by endogenous cold, i.e., deficiency of yang or by exogenous cold transmitted to the interior of the body, mainly manifested by intolerance of cold, pallor, cold limbs, pale tongue with white moistened coating, and deep, slow or fine pulse.

 ✧Interior deficiency-cold syndrome:  an interior cold syndrome resulting from yang deficiency.

 ✦Interior heat syndrome:  a type of interior syndrome caused by pathogenic heat in the internal viscera, especially in the stomach, intestines, lung, liver and gallbladder, mainly manifested by fever, intolerance of heat, thirst, irritability, scanty and condensed urine, full, rapid and forceful or taut pulse, and reddened tongue with yellow coating.

 ✧Exterior-cold and interior-heat syndrome:  a complicated condition seen either in cases with pre-existing internal head and affected by exogenous cold and wind in addition, or in cases with the transformation of exogenous cold into heat after having penetrated into the interior of the body while the pathogenic cold in the exterior of the body is still present. Its main symptoms are the coexistence of both exterior cold(chills and headache with no sweating) and interior heat(fever with irritability, thirst, scanty condensed urine, and constipation).

 ✦Exterior-heat and interior-cold syndrome:  jumbled case with pre-existing deficiency-cold of the spleen and stomach, affected by wind-heat, with symptoms showing the coexistence of exterior heat(fever, headache, and intolerance of wind) and internal cold(cold limbs, loose bowels, etc.)
