The Concept of 6 Evils/ Liu Yin Flashcards
What are the 6 External Evils
Wind Cold Heat Summer heat Dryness Dampness
How do the 6 evils become excess
Overall, the equilibrium between the body and the environment breaks down.
-climate gets too strong, weather occurs unseasonably, weather change is too quick and violent, human being’s defend energy is absolutely or relatively weak.
When is wind predominant
spring
when is cold predominant
winter
when is dryness predominant
autumn
when is dampness predominant
long summer
T/F: the 6 evils can have solo or multiple attack/ the invasion can be conducted by one or more than one evils
True
T/F: the property of 6 evils can be transformed if the pathogens stay inside the body for long time/ during the invasion or retention, the property of pathogens can be changed.
True
The 6 evils invade the body through….
skin and five sense organs
Where does wind invade the body
through wind points (on back), through 5 sense organs, through skin
Wind is a yang pathogen and tends to……
open pores and attack yang areas
ex. common cold, allergies
Wind moves fast and changes quickly
examples: wandering symptoms, acute onset, symptoms run deeper quickly
Wind is a guide pathogen which causes many external pathogen related diseases. examples…
wind cold, wind heat, wind dampness
wind causes itching… ex…
itchy throat, eyes, nose, throat, skin
How do you tx external wind invasions
remove wind
Cold is a (blank) pathogen and tends to injure yang
yin
Cold causes (blank and blank)
blockages and coagulation
Cold- blockage of Qi manifestations
cold pain in abdomen due to cold foods
cold- blockage of blood manifestations
blood stagnation, cyanosis, purple lips when cold
Cold- contraction of muscle and ligaments ex
tension headache
cold- contraction of joint ex
joint arthritis
cold- contraction of channels ex
headache
Heat disease prior to the summer solstice is called (blank) and disease after the summer solstice is induced by (blank)
Wen Bing; Summer heat
SH is yang and tends to cause excessive…..
heat problems
Manifestations: very hot, restless, red face, forceful pulse
SH causes Qi to (blank) thereby consuming Qi and body fluids
rise and disperse
Manifestations: profuse sweating, thirst, scanty and painful urination, dehydration
If with Qi deficiency: SOB, soft voice, fatigue, pale face (heat exhaustion)
SH often combines with which other evil
Dampness
Manifestation: general heaviness, heavy headed, chest tightness and distending, nausea and even vomiting, decrease appetite, diarrhea
Dampness is predominant in which season
long summer
Which organ does dampness attack
Spleen
What are some characteristics of dampness
Dampness is heavy and turbid
Manifestations: heavy sensations (heavy head, joint aches, confusion, foggy and muggy sensation).
Describe Damp Turbid excretions
cloudy urine, sticky and loose stool; profuse vaginal discharge, diarrhea and dysentery, skin blisters with sticky fluids
Dampness is Yin and tends to do what to Qi and Yang?
block the Qi and injure Yang
Manifestations: blocking middle jiao: gas, bloating, decreased appetite, abd distention, tenesmus
Can cause Yang Deficiency
Disease due to dampness can become…
chronic
Ex: damp bi, skin problems, damp-warm diseases
Dampness tends to DESCEND and attack which part of the body?
lower
Ex. profuse vaginal discharge, UTI, beriberi, edema
Dryness tends to attack the body through which two orifices
mouth and nose
Dryness is astringent and dry, therefore it tends to injure (blank)
body fluids
Dryness attacks which organ system
Lungs
Manifestations: dry cough without mucus or with a little sticky mucus but is hard to come out, or cough out blood
Heat and fire cab be seen in which seasons?
All - when the weather becomes hot, it creates heat and fire
Heat is more generalized and superficial symptoms but less severe than fire; fire is much stronger than heat but is more localized.
For example, if a person has pharyngitis and toothache but wihtout fever, chills, then they are due to fire. The carbuncle is another disease typically due to fire
Heat and Fire are Yang pathogens and make Qi….
Rise
Manifestations: yang sxs like high fever, aversion to heat, restless and thirst, profuse sweating, fast and forceful pulses
Heat causes upward disturbance of mind
ex. insomnia, restlessness, tossing and turning, excessive motivation with increasing energy, mania, delirium
Heat and fire causes Qi and body fluid ….
deficiency
Cause Qi def: SOB and fatigue
Body fluid deficiency: thirst desire for cold drinks, dry mouth and dry throat, scanty and hot urination, constipation
Fire and heat can cause inner wind by….
exhausting LV Yin and body fluids and injuring the ligaments and tendons resulting in spasms, convulsions, tremor, shaking of extremities, upstaring eyes, stiff spine and neck
Heat and fire injure small blood vessels causing…
bleeding
Manifestations: epistaxis, vomiting blood, bloody stool or urine, hum bleeding
Heat and fire cause the erosion of muscle and sooner or later they cause swelling of muscle, higher skin temperature, pus and cause a lot of pain
.
What is inner wind
characterized by a group of symptoms including convulsion, tremor, shaking of extremities, deviation of mouth and tongue, vibrating and tetanus, skin twitching and so on.
Since it is closely related to liver dysfunction it’s also referred to as liver wind
What causes inner wind
often caused by the spasm of body tissues including tendon, sinew and ligaments due to the insufficiency of blood, body fluids in the local area
what conditions can lead to the formation of inner wind
extreme heat, liver yang rising, yin deficiency, blood deficiency or blood dryness
What are examples of inner wind due to extreme heat
seen with warm disease with symptoms like convulsion, tetanus, moving nostrils, up staring eyes with high fever, delirium and manie. The typical example is tonsilitis with pus
What are examples of inner with due to liver yang rising
mostly seen in hypertension. It often has an emotion disorder with symptoms sudden fall down and loss of consciousness, deviation of mouth and tongue, stiff tongue, twitching of facial skin, shaking of extremities or hemiplegia. The typical example is wind stroke
What is retention of phlegm and fluid (tan and yin)
defined as a group of symptoms characterized by water metabolism disorder caused by dysfunction of internal organs. Particularly by dysfunctions of SP, LU, and KD. The thicker part is called phlegm while the thinner part is the fluid retention
Describe invisible phlegm
stays inside the body, such as diaphragm, brain, subcutaneous nodule, channels. The symptoms can be recognized as phlegm retention, Tongue and pulse help the confirmation.
What causes phlegm
invasion of external pathogens, irregular diet, seven emotions disorders; dysfunction of SP, LU, KD
The retention of fluid stays in gastrointestinal areas, hypochondriac area and skin area, while phlegm flows with the disorder of energy flow and spread through whole body to internal organs, bone, ligaments and even brain
.
What are the 4 subtypes of fluid retention
Phlegm retention
Pleural effusion: fluid retention in the hypochondrium
Anasarca: generalized edema
Excessive: fluid retention at the hypochondrium and epigastrium
Describe phlegm stagnated in the lungs
cough with mucus, asthma and wheezing
describe phlegm blocks the heart
chest tightness, chest pain
phlegm blocks the orifice of the heat
dull, wooden, incoherent speech
phlegm fire harassing heart shen
mania, restlessness
phlegm stays in stomach
nausea and vomiting, fullness in epigastriu,
phlegm blocks channel, ligament and bones
nodules along channels, numbness of extremities, furuncles
phlegm blocks head
dizziness, vertigo, confusion, foggy thinking
phlegm stocks in throat
plum pit qi
fluid retention in the intestines
noises in abdomen
fluid retention in chest and hypochondriac area
chest distending, cough with chest pain
fluid retention in chest and diaphragm
chest tightness, cough and dyspnea, could not lie dow, edema and puffy eyes and face
fluid retention in skin
edema, without sweating, body aching and heaviness
define blood stagnation
blood slows down and becomes congested
define blood stasis
result of blood stagnation and indicates the blood flowing stopped or the blood comes out of blood vessel byt still stays inside the body
What can cause blood stasis/stagnation
Qi deficiency, Qi stagnation; Cold in blood; heat in blood; traumatic event
S/S of blood stasis/stagnation: Pain:
Pain: pricking pain, fixed and aversion to touch and worse at night
S/S of blood stasis/stagnation: Masses or bruises
swelling of local area, bruise; tumor, cancer
S/S of blood stasis/stagnation: bleeding
purple in color with purple clots
Clinical findings with blood stagnation/stasis: Inspection:
cyanosis or darkness, scaly skin, thick and dry, purple lips and purple tongue body with purple spots’ the veins underneath is swollen and purple
Clinical findings with blood stagnation/stasis: Pulse
thready, hesitant/choppy, deep wiry or knotted and/or intermittent pulses
