Pinyin
shì dòng
Simplified
是动
Literal
是 shì — this; 動 dòng — to stir, to move. The formula introduces the symptoms that arise when the channel itself is stirred, as distinct from the diseases of the organ it belongs to.
Shuowen
《說文》:動,作也。「是動」本篇12見,十二經各一;「所生病」12見,亦十二經各一。二語對舉,為《經脉》全篇之骨幹。

In brief

The first half of the chapter’s double formula. 是動則病… — when this moves, the disease is… — introduces the symptoms produced by the channel as a conduit: swelling, pain, heat, stiffness along its course. The second half, 是主…所生病者, introduces the diseases of the organ the channel belongs to. The distinction between them, debated for a thousand years, is the chapter’s chief contribution to clinical method.

The Lung channel of Hand Taiyin arises in the middle burner, descends to connect with the large intestine, returns along the stomach mouth, passes the diaphragm and belongs to the lung; from the lung system it comes out sideways below the armpit, descends along the inner side of the upper arm, in front of the shaoyin and the pericardium, to the middle of the elbow; along the inner side of the forearm above the bone, to the inch opening, up the thenar eminence, along the fish border, and out at the tip of the thumb. Its branch separates behind the wrist and goes straight out to the inner side of the index finger, to its tip. When this moves, the disease is swelling and fullness of the lung, with panting and coughing, pain in the supraclavicular hollow, and in severe cases crossing the two hands over the heart with dim sight: this is arm reversal. What it generates is coughing, rising qi, panting and gasping, vexation of the heart, fullness of the chest, pain and reversal along the inner front of the upper arm, and heat in the palm. When the qi is abundant and in excess there is pain of the upper back and shoulders, wind-cold, sweating with wind-stroke, and frequent urination with yawning; when the qi is deficient there is pain and cold of the upper back and shoulders, scant qi insufficient for breathing, and a change in the colour of the urine. For all these diseases, reduce where abundant, supplement where deficient, speed the needle where hot, retain it where cold, apply moxa where sunken, and where neither abundant nor deficient take from the channel itself. Where abundant, the inch opening is three times the neck pulse; where deficient, the inch opening is smaller than the neck pulse.
十二經皆以「是動則病」起,以「是主某所生病者」承,以「爲此諸病」結。「是動」12見,「所生病」12見,二者一經一藏,為後世經病、藏病之分所自出。
