Syndrome Differentiation for Lung and Large Intestine

Syndrome Differentiation by Lung and Large Intestine

There are 12 patterns of the syndrome in the lung and large intestine systems.


1. Wind cold attacking the lung


Cough with thin sputum, aversion to cold with mild fever, nasal obstruction, running nose (with thin discharge), no sweating, headache and body ache, thin white tongue-coating, superficial tense pulse.



a. lung qi refrained from dispersing

lung qi adversely rising

qi not spreading fluids

lung orifice blockage


b. Defensive qi and the superficial being restricted

lack of warmth from defensive qi

defensive qi being blocked

cold pathogen contracting channels

cold pathogen constricting pores


2. Wind heat attacking the lung


Cough with yellow thick phlegm, nasal obstruction with thick discharge, fever with mild aversion to cold, slight thirst, or sore throat, red tip of the tongue, thin yellow coating, superficial rapid pulse.



lung qi adversely ascending due to failing in descending

wind-heat “drying” fluid into phlegm

wind-heat disturbing throat upward

wind-heat disturbing in the nose

wei defensive qi battling the pathogen

wei defensive qi being restricted from warming


3. Dryness attacking the lung


Dry cough with little sticky sputum (difficult being spit out), or chest pain (in serious cases), a thread of blood in phlegm; dry mouth, lips, nose and throat; fever, slight aversion to cold, dry stool, scanty urine; thin and dry tongue-coating, floating and rapid pulse or floating and tight pulse.



a. dryness attacking lung

lung lacking moisture

cough damaging lung collaterals


b. dryness damaging body fluid


c. attacking the superficial, wei qi dysfunction


4. Cold attacking the lung


Cough, shortness of breath, white thin sputum, cold limbs, pale tongue, white coating, slow or moderate pulse.



a. cold disturbing lung

lung qi rising (disharmony of dispersing and descending)


b. cold contracting

water fluid accumulation

skin losing warming

the hindering flow of qi and blood


5. Phlegm-damp blocking the lung


Cough with profuse white phlegm, oppressed chest, asthma (in severe cases), pale tongue with white greasy coating, slippery pulse.



blocking lung,

lung qi adversely rising

blocking air path


6. Excessive heat in the lung


Fever, thirst, cough, asthma, flaring of nares, chest pain, sore and swollen throat, nose flapping, yellow scanty urine, constipation, red tongue, yellow coating, rapid pulse.



a. heat permeating inside the lung

lung qi adversely rising heat “steaming” the throat, qi and blood stagnating lung opening into the nose, lung qi blocking: nose flapping


b. heat disturbing inside the body


7. Phlegm heat obstructing the lung


Cough with profuse yellow sputum, fullness in the chest, even asthmatic breathing with sputum gurgling in the throat, irritability, fever, thirst, or coughing stinky blood mixed phlegm, chest pain, constipation, scanty dark urine, red tongue with yellow greasy coating, slippery rapid pulse.



a. pent-up lung qi


b. heat disturbing inside lung

lung collaterals

qi and blood stagnation

rotting flesh and blood

c. interior heat disturbing


8. Lung qi deficiency


A low-pitched cough worsening on exertion, clear thin sputum, shortness of breath, low voice, or spontaneous sweating, aversion to wind, easily catching a cold, tiredness, pale complexion, pale tongue with a white coating, and a weak pulse.



qi adversely rising

pectoral qi weak

exertion using up qi

fluid concentrated into phlegm

wei – surface weak


9. Lung yin deficiency


dry cough with little sputum, or scanty sputum difficult spitting out, dry mouth and throat, bodyweight loss, hot sensation in the five centres, afternoon fever, night sweating, flushed cheeks, hoarseness, dry and red tongue, thready rapid.



heat “burning” lung, lung qi rising

fire “burning” lung collateral

throat damaged by fire

fire disturbing interiorly

10. Damp heat in the large intestine


Abdominal pain, diarrhea with purulent and bloody stools, tenesmus, or spouting diarrhea with stinking stools, accompanied by a hot sensation in the anus, fever, thirst, scanty yellow urine, a red tongue with a yellow greasy coating, and a slippery rapid pulse.



qi blood stagnation, “flesh” and blood rotting

heat pushing fluid down

qi stagnation

heat permeating the large intestine

heat damaging fluid

heat radiating out


11. Fu-excess heat in the intestine


High fever, or afternoon fever (2 to 4 pm), abdominal hardness and pain (worsening under palpation), constipation (or combining thin watery but stinky stool, sweating, thirst, even delirium, “craziness”, scanty yellow urine, red tongue, thick dry yellow coating



heat damages large intestine fluid, resulting in the combination of heat and dry faces

heat disturbing upward (heat)heat striving out fluid


12. Intestine dryness


Constipation with dry stools that are difficult to defecate, dry mouth or bad breath, dizziness, red tongue with yellow dry coating, thready thin pulse.
