If holism describes how Chinese medicine looks at a person, this lesson describes what it is looking for. Health, in this tradition, is not the mere absence of disease. It has two positive faces: balance and flow. Grasp these two, and you hold the target that all treatment aims at.
Balance
The body is a play of opposing but complementary forces — warming and cooling, active and quiet, rising and descending, filling and emptying, moistening and drying. Health is their dynamic equilibrium. Note the word dynamic: this is not a frozen, motionless balance but a living one, constantly adjusting, like a tightrope walker who stays upright precisely by making countless small corrections.
When one side grows too strong or too weak, the balance tips, and symptoms appear. The classical language for this is elegant and practical:
- too much of something is an excess (shi) — too much heat, too much damp, an obstruction;
- too little is a deficiency (xu) — too little Yang, too little Blood, a depletion.
The physician’s first task is to read which way the balance has tipped, and then to correct it in the opposite direction: cool what is too hot, warm what is too cold, drain what is in excess, tonify what is deficient. Almost every treatment principle in Chinese medicine is a variation on restoring a tipped balance.
Flow
The second face of health is free movement. It is not enough for the substances to be present in the right amount; they must also circulate freely. Qi, Blood and Body Fluids must move smoothly through the channels and the organs, reaching every part and returning. Where they flow freely, there is comfort, warmth and normal function. Where they stagnate — slow, pool or block — there is trouble.
A famous classical couplet captures the whole idea:
"Bu tong ze tong; tong ze bu tong." "Where there is no free flow, there is pain; where there is free flow, there is no pain."
The forms of stagnation are worth knowing in advance, because you will meet them everywhere:
- Qi stagnation — a functional, moving blockage: distension, bloating, tension, a sense of oppression, mood that rises and falls, symptoms that come and go and shift with emotion;
- Blood stasis — a deeper, more fixed blockage: sharp or stabbing pain in one fixed spot, dark or purplish discolouration, masses;
- Fluid stagnation — fluids that fail to move gather as dampness, oedema, or congeal into phlegm, bringing heaviness, swelling and obstruction.
Two faces of one health
Balance and flow are not two separate goals; they are two aspects of one healthy state, and they sustain each other. Good balance keeps things moving — for example, sufficient Yang provides the warmth that keeps Qi and Blood flowing. And free flow preserves balance — movement prevents the local excesses and deficiencies that stagnation creates.
This is why, once you learn to think in these terms, the whole of pathology begins to simplify. Almost every pattern you will study is, at bottom, a disturbance of one or both: something out of balance, or something not flowing — often both together, one causing the other. And almost every treatment, whatever its method — needle, herb, moxa or movement — has the same underlying aim: to restore balance and to free the flow. Keep this simple double target in view, and the many details ahead will always have a place to belong.
