Zhàngnüè zhǐnán 瘴瘧指南
A Guide to Miasma-Malaria by 鄭全望 (Zhèng Quánwàng, late Míng, fl. early 17th c.)
About the work
A late-Míng monograph on miasma-malaria (zhàngnüè 瘴瘧) — the cluster of febrile / intermittent-fever / convulsive disorders associated with the zhàng 瘴 “noxious miasma” of the Lǐngnán southern frontier — in 2 juǎn, by the Jiāngxī physician Zhèng Quánwàng. Preface dated Wànlì 37 (1609), tenth month, first day. The work is the principal late-Míng monograph on miasma-malaria, continuing the Sòng-period Zhàngnüè wèishēng fāng 瘴瘧衛生方 tradition of 李璆 Lǐ Qiú and 張致遠 Zhāng Zhìyuǎn and adapting it to late-Míng clinical experience.
Abstract
The immediate motivation for the book, set out in Zhèng’s preface, was the Wànlì 30 (1602) epidemic — a year in which the autumn was unusually hot and the winter mild, and an epidemic followed with hybrid clinical features: malarial in onset but with continuous (rather than intermittent) fever; Shānghán-like but with all three-yáng channels and the tàiyīn / shàoyīn channels involved simultaneously; internal-injury-like but with the qìkǒu pulse not exceeding the rényíng pulse. Treatment by Shānghán methods killed patients in seven days; treatment as internal-injury or malaria also failed; “even the old practitioners’ clinical resources were exhausted” (老醫宿匠，計與術兩窮).
Zhèng’s principal doctrinal contributions:
-
Climatic-historical framing. Zhèng records the long-term southward expansion of “miasma” territory: in Táng times Lǐngnán still had snowfall, in his own time it no longer did; correspondingly the zhàng zone has expanded northward, with Luòyáng now subject to “cuckoo weather” 杜鵑天氣. This is a striking early example of climatic-historical reasoning in Chinese medical writing.
-
Differential diagnosis of internal-injury versus zhàngnüè. Internal-injury fever subsides briefly when the patient throws off the bedclothes; rèzhàng heat does not subside even on cold ground. Internal-injury pulse: qìkǒu alone is large and fast at 6 beats/breath; rèzhàng pulse: all six pulses are surging-and-fast at 7–8 beats/breath. The two are easily confused, with grave consequences for misadministered treatment.
-
Critique of Bǔzhōng yìqì tāng 補中益氣湯 misapplication. If zhàngnüè is wrongly diagnosed as internal-injury and treated with Bǔzhōng yìqì tāng, the fever worsens and consciousness deteriorates further — because zhàngnüè is caused by failure of yángqì to descend, and the shēngmá 升麻 / cháihú 柴胡 in the prescription drive the already-rising yángqì still higher, while the huángqí 黃耆 / báizhú 白朮 close the surface and prevent sweating that would discharge the heat.
-
Paediatric zhàng presentations are addressed at length — children unable to describe their symptoms (the “silent science” 啞科) require wàngwénwènqiè examination of voice, complexion, behaviour, and hǔkǒu 虎口 (“tiger’s mouth”) finger-vein examination.
-
Post-zhàng dysentery is given detailed prescription guidance, including the dangerous jìnkǒu lì 噤口痢 (locked-mouth dysentery) presentation, with cautious analysis of whether the underlying state is true spleen-weakness (requiring tonification) or post-sùqiào 粟殼 (poppy-shell) iatrogenic damage.
The book is one of the most clinically substantial Míng monographs on southern-frontier medicine and continues to be referenced in the modern TCM literature on tropical infectious disease.

Other points of interest
The 1602 epidemic context that prompted this book is part of the late-Míng cluster of catastrophic epidemics that culminated in the great 1641 epidemic responded to by 吳有性 Wú Yǒuxìng (see KR3eg004). The two together — Zhèng’s 1609 Zhàngnüè zhǐnán and Wú’s 1642 Wēnyì lùn — bracket the late-Míng emergence of specialised Chinese-medical writing on epidemic disease.
