傷寒五六日，嘔而發熱者，柴胡湯證具，而以他藥下之，柴胡證仍在者，復與柴胡湯，此雖已下之，不爲逆，必蒸蒸而振，卻發熱汗出而解。若心下滿而鞕痛者，此爲結胸也，大陷胸湯主之。但滿而不痛者，此爲痞，柴胡不中與之，宜半夏瀉心湯。

After five or six days of cold damage with vomiting and fever, the signs of Bupleurum Decoction are complete; if another drug is used to purge and the Bupleurum signs remain, give Bupleurum Decoction again. Though purged, this is not a mistreatment: he will shake and steam, then break into fever and sweat and be resolved. If the epigastrium is full and hard with pain, this is chest binding, and Major Chest-Binding Decoction governs it. If it is full without pain, this is fullness, and Bupleurum is not to be given; Pinellia Heart-Draining Decoction is suitable.
痞之正訓：但滿而不痛。與結胸對舉，全篇之綱在此。
脉浮而緊，而復下之，緊反入裏，則作痞，按之自濡，但氣痞耳。

A floating, tense pulse, purged again: the tension turns inward and makes fullness. It is soft on pressure; it is only a fullness of qi.
「按之自濡，但氣痞耳」——無形之氣，故不可攻。
傷寒中風，醫反下之，其人下利日數十行，榖不化，腹中雷鳴，心下痞鞕而滿，乾嘔，心煩不得安。醫見心下痞，謂病不盡，復下之，其痞益甚。此非結熱，但以胃中虚，客氣上逆，故使鞕也。甘草瀉心湯主之。

In cold damage or wind-strike the physician wrongly purges, and the patient has dozens of stools a day, undigested grain, rumbling in the abdomen, hardness and fullness below the heart, dry retching, and restlessness that gives no peace. Seeing the fullness, the physician says the disease is not exhausted and purges again, and the fullness grows worse. This is not bound heat, but only emptiness of the stomach with alien qi rising, which makes it hard. Liquorice Heart-Draining Decoction governs it.
屢下而痞益甚，乃胃虚客氣上逆；「此非結熱」四字，最忌再下。
病發於陽而反下之，熱入因作結胸；病發於陰而反下之，因作痞。所以成結胸者，以下之太早故也。

When a disease arising from yang is wrongly purged, the heat sinks in and makes chest binding; when one arising from yin is wrongly purged, it makes fullness. Chest binding forms because the purgation was given too early.
結胸與痞同出誤下，一陽一陰，來路分明。
