In brief

What heat becomes when it settles, in chapter 17’s list of how an illness changes once formed: 癉成爲消中 — heat (癉, dān) becomes wasting in the centre. The word 消 is the same one the book uses for melt and for consume, and the classical picture is of a man who eats and is not nourished: the centre burns it away faster than it can be used. The chapter places it in a chain — wind becomes cold and heat, heat becomes wasting in the centre, counterflow becomes disease of the crown, standing wind becomes food-diarrhoea, wind in the vessels becomes pestilent sores — and then says the transformations cannot be counted.

帝曰:病成而變,何謂?歧伯曰:風成爲寒熱,癉成爲消中,厥成爲巔疾,久風爲飱泄,脉風成爲癘。病之變化,不可勝數。 帝曰:病成而变,何谓?岐伯曰:风成为寒热,瘅成为消中,厥成为巅疾,久风为飧泄,脉风成为疠。病之变化,不可胜数。

The Emperor says: What does it mean that an illness, once formed, changes? Qibo says: Wind, once formed, becomes cold and heat; heat, once formed, becomes wasting in the centre; counterflow, once formed, becomes disease of the crown; long-standing wind becomes food-diarrhoea; wind in the vessels becomes pestilent sores. The transformations of illness cannot be counted.
本篇論「病成而變」:風成為寒熱,癉成為消中,厥成為巔疾,久風為飱泄,脉風成為癘,而結以「病之變化,不可勝數」。癉讀 dān,熱也;消中之消,說文作「盡也」,喻中焦消爍、善食而瘦。與第十二篇「熱中」同屬中焦,而彼言熱、此言消。

溺黄赤安卧者,黄疽。已食如飢者,胃疸。 溺黄赤安卧者,黄疽。已食如饥者,胃疸。
niào huáng chì ān wò zhě, huáng jū. yǐ shí rú jī zhě, wèi dǎn.
Urine that is yellow and red, with the person lying at rest, indicates jaundice. Having eaten and yet being hungry indicates stomach jaundice.
「已食如飢者,胃疸」:胃疸即中消——食已而飢,胃熱之甚者。與第十七篇「癉成爲消中」同條而義進:第十七篇以癉(音 dān)之成為消中,本篇則舉其候——已食如飢,即消中之發於胃者,故名胃疸。疸音 dǎn,《說文》:黃病也;本篇「溺黄赤安卧者,黄疽」「目黄者曰黄疸」則疸之正候,其「黄疽」之疽《說文》訓癰,二字同篇互見,各從底本。

帝曰:消癉虚實何如?歧伯曰:脉實大,病久可治;脉懸小堅,病久不可治。 帝曰:消瘅虚实何如?歧伯曰:脉实大,病久可治;脉悬小坚,病久不可治。
Dì yuē: xiāo dān xū shí hé rú?Qí bó yuē: mài shí dà, bìng jiǔ kě zhì; mài xuán xiǎo jiān, bìng jiǔ bù kě zhì.
The Emperor says: what of the vacuity and repletion in wasting-and-thirsting? Qibo says: if the pulse is replete and large, a long illness can still be treated; if it is hanging, small and hard, a long illness cannot be treated.
「消癉虚實何如?…脉實大,病久可治;脉懸小堅,病久不可治」——消癉與消中同屬消爍之病,本篇之答以脉之大小兼病程之久暫為斷,是本篇惟一一處以久暫與脉象並斷者。**「消」讀 xiāo**;**「癉」讀 dān,本篇二見**,與「疸」形近而音義皆異;「懸」讀 xuán;「堅」讀 jiān,本篇三見;「久」讀 jiǔ。脉實大而病久猶可治者,以脉有胃氣;脉懸小堅而病久者,胃氣已敗。上文「凡治消癉…肥貴人,則高梁之疾也」則推其病因。

Now those who have heat-within and wasting-within are all men of wealth and station. To forbid rich grain is not to suit their hearts; to forbid aromatic herbs and mineral drugs is to leave the illness unmended. I wish to hear your account of it.
**「夫熱中、消中者。皆富貴人也」——底本「者」下作句號,今照錄不改**,**其義仍是一句**;**通行本作讀號,異文見本篇校勘**。**本篇「消」2見**,**「消中」2見**,皆與「熱中」連稱;「皆」讀 jiē、**本篇3見**;「富」讀 fù、「貴」讀 guì、**各1見、1見**;「禁」讀 jìn、**本篇2見**;「愈」讀 yù、**本篇1見**;「願」讀 yuàn;「説」讀 shuō,**不作「說」**。**消中與熱中並禁高梁、芳草、石藥**:**禁者非薄其物,乃以其氣與病之熱同類**——**下文「熱氣慓悍,藥氣亦然,二者相遇」即此二病之通解**。

How it has been translated

Every rendering below is a decision about which reader is being addressed. There is no neutral option.

Common Englishcentral wasting, or middle wastingThe clinical literature renders 中消 as central dispersion or middle wasting.
This sitewasting in the centre消 is 盡, to be used up, and 說文's own example is ice dissolving — something solid going away by degrees. Centre is kept rather than middle burner because the chapter gives no burner vocabulary here; it only says 中. The phrase also lets the reader hear the kinship with the later 消渴 without importing that diagnosis into a chapter that is listing transformations, not diseases.
