Eight Principles Flashcards
What are the Eight Principles?
Exterior-Interior
Cold-Heat
Vacuity-Repletion
Yin-Yang
What is a Combination disease? What are some examples?
- A two or three-fold concurrence of either unpaired principles, or of interior & exterior.
- e.g. Interior-exterior combination disease.
- e.g. Vacuity-heat-interior combination disease.
- NOTE: Most diseases fall into the category of Combination disease.
What is a Conversion disease? What are some examples?
- Displacement of sx of one principle by sx of the opposing principle of the pair.
- e.g. External pattern converts to an interior pattern (generally indicates abatement of right qi & advancing pathogenic qi).
- e.g. Interior pattern exits to exterior (generally indicates recovery of right qi & abatement of pathogenic qi).
- e.g. Cold pattern converts to heat pattern.
What are some factors that affect Conversion disease?
- Strength of pathogenic qi
- Vacuity of right qi
- Inappropriate treatment
What is a Complex disease?
Two possibilities for Complex disease (both are contradictory, but there are signs of coexistence):
1) Simultaneous cold & heat
2) Simultaneous vacuity & repletion
What are some examples of Complex disease?
- True Heat & False Cold
- True Cold & False Heat
- True Repletion & False Vacuity
- True Vacuity & False Repletion
What are the essential signs & sx of an Exterior disease?
1) Aversion to Wind or Cold
2) Fever or Chills
3) Floating pulse
4) Acute or short duration of signs & sx
What is the pathomechanism for aversion to wind or cold?
Depression of lung defense / wei qi causes aversion to wind or cold.
What is the pathomechanism for headache & limb pain?
Pathogenic qi obstructs qi & blood flow in the channels, causing H/A & limb pain.
What is the pathomechanism for nasal congestion & cough?
Obstruction of lung diffusion causes nasal congestion & cough.
What is the pathomechanism for cold leading to lack of sweat?
Cold constricts the pores, so there is no sweat.
What is the pathomechanism for cold leading to sweat?
- Patient is deficient and Wei Qi is vacuous, so pores stay open and there is sweat.
- Or, Ying Qi is vacuous, therefore not contained internally and comes out as sweat.
What are the main causes of internally generated disease (aka Interior disease)?
1) Externally-contracted pathogens penetrate to the interior (conversion of Exterior disease to Interior disease).
2) Direct strike of external pathogens to the interior.
3) Other causes including: affect-mind damage, dietary irregularities, taxation fatigue, viscera-bowel or qi-blood irregularities, medications
What is “direct strike”? What are some examples?
- When something has penetrated the interior directly.
- e.g. eating something cold, like ice cream or salad
- e.g. eating something very hot
- e.g. injection of something like chemotherapy or flu shot
- e.g. immersion into cold water
What are some general signs & sx of Interior disease?
- Pulse is deep (does not necessarily mean cold or vacuous).
- Disease course generally long.
- Disease generally more severe.
- Disease onset may be either acute or insidious.
- No aversion to wind or cold.
- No floating pulse.
