Basic principlesSasang (four Images) theory (SE, TE, SY, TY)Yin-Yang theory, five elemental-phases theory: (wood, fire, earth, metal, water)Tridoshas (Vata, Pitta, Kapha), five elements: (ether, air, fire, water, earth)

Physiological equilibrium model(1) Spleen-kidney seesaw: (the strong state of the spleen and the weak state of the kidney predetermines the SY type, is inversed in the SE type).

(1) Balance between Yin and Yang (follows the principle of waxing and waning, mutual restraining and mutual nourishing of Yin and Yang).
239659.tab.004
Balance among the tridoshas means that all of the doshas are functioning correctly in appropriate proportions to each other and in the right positions.

(2) Lung-liver seesaw (the strong state of the lung and the weak state of the liver predetermines the TY type, is inversed in the TE type).

- Vatta governs communication, transportation and movements.
-Pitta governs digestion, transformation and metabolism.
-Kapha governs connecting structure, cohesion and lubrication.

Pathological modelDiseases and illnesses are caused by the aggravation of hypoactive visceral functions; the four constitutional types of SE, SY, TY and TE types each have different hypoactive viscera or weak organ, namely the spleen, kidney, lung, and liver, respectively.
