Mechanism of Disease Theory:the basics.
The Basics: The basics for the Mechanism of Disease Theory are briefly as:
✵Wind moves swifly and is changeable. When wind prevails, involuntary movements occur. Wind is the chief of many diseases.
✵Cold, as a yin pathogen, is likely to damage Yang Qi. cold is congealing and tends to cause stagnation. Cold is characterized by contraction.
✵Dampness is characterized by heaviness and stickiness. Dampness is viscous and tends to stagnate. When dampness prevails, Yang is debilitated. When dampness prevails, diarrhea occurs.
✵When dryness prevails, desiccation occurs.
✵Fire is characterized by flaring up. Qi in excess will turn into fire.
✵Excessive Joy injures the heart. Joy makes heart Qi relax. anger injures the liver. Anger makes liver Qi rise. Worry injures the lung. Worry makes
✵Qi stagnate. Sadness makes lung Qi disperse. Anxiety injures the spleen. Anxiety makes spleen Qi stagnate. Fear injures the kidney. Fear makes kidney Qi descend. Fright makes Qi disturbed. Cold makes Qi compact. Heat makes Qi dispersed. Strain makes Qi consumed.
✵All wind with vertigo and shaking is ascribed to the liver.
✵All cold with contraction is ascribed to the kidney.
✵All Qi rushing and oppression is ascribed to the lung.
✵All dampness with swelling and fullness is ascribed to the spleen.
✵All fever with impaired consciousness and convulsion is ascribed to fire.
✵All painful and itching sores are ascribed to the heart.
✵All cold extremities, constipation and diarrhea are ascribed to the lower part.
✵All atrophy, dyspnea and vomiting are ascribed to the upper part.
✵All trismus with shivering chills and delirium is ascribed to fire.
✵All spasms and neck ridigity are ascribed to dampness.
✵All disorders with upward perversion are ascribed to fire.
✵All abdominal distension and fullness is ascribed to heat.
✵All states of agitation and mania are ascribed to fire.
✵All sudden muscular spasm and rigidity is ascribed to wind.
✵All abdominal distension like a drum with borborymi is ascribed to heat.
✵All illnesses with swelling and aching of the instep and mental strain are ascribed to fire.
✵All cramps, rigidity, and turbid urine are ascribed to heat.
✵All thin, clear and watery discharge is ascribed to cold.
✵All acid eructation and spouting diarrhea with urgency for evacuation are ascribed to heat.
✵Excess syndromes occur when the pathogenic factors are in abundance.
✵Deficiency syndromes occur when the patient's essential Qi is severely damaged.
✵Preponderance of Yin gives rise to cold syndrome.
✵Exuberance of Yang gives rise to heat syndrome.
✵Deficiency of Yang brings on external cold. Deficiency of Yin brings on internal heat. Deficiency of Qi brings on cold.
