Wen Bing 1

Wen Bing

(warm diseases)

Chapter 1    Concept of Wen Bing

Concept:  A class of  acute febrile diseases

Etiology: external warm pathogen

Chief symptom: fever

Pathogenic feature: heat predominant,  heat tending to transform into dryness and damage b fluid (yin)


A. Features of wen bing

  1. Causes/pathogens

Warm pathogens:   (wind, heat, + summer heat, dryness) + heat or damp heat

li qi/pestilence

  1. Four features

Infectious:  refers to most diseases, some are not infectious

Spreading:  most




  1. Progress

mild → severe (b f damage)

shallow → deep

excess → deficiency

wei qi ying xue and san jiao


  1. Clinic features

rapid onset, change quickly,

fever (chief symptom)

dryness + yin def

adversely sunk to the interior:   internal bleeding, internal wind (tremor), coma


B. Coverage and classification of wen bing

Classification (by pathogens): two groups

Warm pathogens — not combine with damp  → wen re bing (warm heat diseases)

— combine with damp → shi re bing (damp heat diseases)

Comparison of two kinds of wen bing

Wen re bing

(warm heat diseases)

Shi re bing

(damp heat diseases)

PathogenHeat without damp

(feng wen, shu re, zao re)

Combine with damp

(shi re, shu shi)

locationLU, exterior  (mostly)

Yang ming or HT ying (some)

SP/ST, or shao yang, or mo yuan
Occurrence, transmission,




Not lasting

Slow onset,


Long lasting

SyndromeHeat signs, tending to damage yin and produce drynessIn the beginning, signs of fever and yin damage are not apparent, obstruction of yang qi is the main pathogenic change
diseasesFeng wen (wind warmth),

chun wen (spring warmth),

shu wen (summer warmth),

qiu zao (autumn dryness),

massive head scourge – 大头瘟

Shi wen (damp warmth),

fu shu (hidden summer heat ),

shu shi

(summer heat mixed with damp)


Chapter 2   Etiology and occurrence of wen bing

  1. Etiology

Pathogens of wen bing:

Warm heat (in six climatic factors)Feng re (wind heat)

Shu re   (summer heat)

Shi re    (damp heat)

Zao re   (dryness heat)



Seasonal wen bing



Pestilence (Li qi)              pestilenceWen yi (Plague Diseases)
Warm heat (incubation)Hidden cold transforming into heatChun wen (spring warm)
Warm toxin Wen du (Warm toxin)


  1. wind heat /feng re                      wind warm / feng wen — disease

–  mouth, nose,  — LU

–  change into dryness – damage body f

– *change rapid:     —;  PC


  1. summer heat /shu re

yang ming – qi level

PC, LV wind

Damp —  qi


  1. damp heat / shi re


Change slowly,  long course

Qi movement stg


  1. dryness heat / zao re

–  LU

–   damage b fluid

–  transformation of fire

dry à fire:  red eyes, sore throat/gum, tinnitus


***5. warm heat  /wen re

– from internal

– complicated,    blocking HT, producing wind, moving bleeding

– damaging yin  ( LV/KI)


***6. warm toxin (wen du)

–  travel along a path

– stagnated


  1. li qi (pestilence)

– infectial highly, epidemic

– through mouth/nose

– critical


B. occurrence

  1. causes:

natural factors:


social factors:

  1. route:

mouth/nose; skin /pores

  1. patterns:
 Newly contractedIncubation*
OccurrenceFrom externalStart from the internal
Symptoms High fever, thirst, darkish urine, red tongue, yellow c; or delirium, deep red t, no c,
progress Internal à external; or further deep

Chapter 3      syndrome differentiation

  1. Four levels

Wei level syndromes    3 types:

-Wind heat invading wei level

Manifestations:  tongue tip red

-Dryness heat invading wei level

Manifestations:  dry cough

-Damp heat invading wei level

Manifestations:  aversion cold, fever, headache (heavy, wrapped),

heavy body (tired limbs), stuffy chest/abd

Qi level s  

Locations: LU, St, SP, Int, GB, diaphragm, mo yuan (half int half ext)

Main symptoms: fever, no aversion to cold, thirst, yellow coat


PF →  Wei  → qi

PF   →qi

(Latened  PF)  → qi

Ying  → qi


Ying level s  

Main symptoms:  fever (worse at night), dry mouth (drinking a little water), irritability, insomnia, “skin rashes”, crimson T (deep red color)


PF (qi level) → ying level

PF (wei level) → ying level

PF (incubated in ying) → ying level


Xue level s    

Main symptoms: fever (hot), irritability, delirium, bleeding (various), “skin rashes” (lots, vast), crimson (deep red ) T


PF (ying level) → blood level

PF (wei or qi level) →

PF (incubated in blood level) →


PF reducing → APF increasing

APF decreasing  →  zang organs deteriorating

Severe bleeding  →  qi collapsing

PF gradually reducing  →  LV/KI yin damaging

  1. Tripple jiaos

Upper jiao:


– epi →  LU/wei

– LU heat

– damp heat in LU


–  PF  → PC  (ying level)

– damp misting PC

Middle j


– yang ming heat

– yang ming heat + abd qi obstruction

– damp heat in int


– Damp heat  (–middle j)

Lower j


-KI essence def

-LV def → wind/tremor
