The *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet) states: There are three diseases in women immediately after childbirth, one of which is Jing syndrome (spasm). What does this mean? It is said: After childbirth, blood deficiency occurs, accompanied by profuse sweating and a predisposition to wind pathogen invasion, thus leading to Jing syndrome.

Guo Jizhong stated: Postpartum blood deficiency leads to loose cou li (skin pores and interstices), resulting in profuse sweating. If wind pathogen invades and binds with it, Jing syndrome develops. Jing syndrome manifests as trismus or difficulty opening the mouth, rigidity and straightening of the back, resembling an epileptic seizure, head shaking, sounds like neighing horses, opisthotonos (body bending backward), breathlessness as if severed, sweating like rain, and picking at empty air; these are untreatable critical conditions.

Xue Lizhai stated: Postpartum Jing syndrome arises from excessive blood loss and depletion of Yuan Qi (primordial qi), or binding with external pathogens, causing trismus, spasticity and rigidity of the four limbs, or opisthotonos and limb convulsions. If there is sweating and no aversion to cold, it is called Rou Jing (Soft Spasm). If there is no sweating and aversion to cold, it is called Gang Jing (Hard Spasm). However, when occurring postpartum, it is caused by excessive blood loss leaving the sinews without nourishment. One should greatly tonify Qi and Blood, and safety can usually be ensured. If one attacks the wind pathogen, death is inevitable.

Miao Zhongchun stated: Postpartum blood deficiency leads to opisthotonos, named Jing syndrome. "Jing" means stiffness. Excessive blood loss causes sudden deficiency of Yin Qi. Yin deficiency generates internal heat; extreme heat generates wind, thus manifesting external wind symptoms. The essence is insufficient Yin and Blood failing to nourish the sinews. This is a sign of severe deficiency of the Foot Jueyin Liver Meridian. One should nourish Yin and tonify Blood, and clear heat for recovery.

Xue Lizhai stated: Zhang Zhongjing said that in Shang Han (Cold Damage) disease, sweating indicates Rou Jing, treated with Guizhi Tang (Cinnamon Twig Decoction). No sweating indicates Gang Jing, treated with Mahuang Tang (Ephedra Decoction). When contracted postpartum, both Qi and Blood are deficient. Critical postpartum syndromes should not be viewed according to standard Shang Han protocols. Zhu Danxi stated that postpartum treatment should primarily focus on greatly tonifying Qi and Blood, frequently administering Renshen (Ginseng Root), [missing character, likely Baizhu], and Fuzi (Aconite Root). Wind stroke here is a manifestation of extreme deficiency; consolidating the root Yuan Qi will cause various diseases to recede naturally.

Lou Quanshan stated: Xiao Xuming Tang (Minor Xu Ming Decoction), Dadouzi Tang (Soybean Purple Decoction), and Juqing Gubai San (Ju Qing Gu Bai Powder) are all formulas targeting the Taiyang and Jueyin meridians. They are suitable if the pathogen is excess and the pulse is floating, wiry, and forceful. However, for postpartum patients with severe Qi and Blood deficiency, one should not lightly induce sweating to release the exterior. Using Fangfeng Danggui San (Saposhnikovia and Angelica Powder) is the superior approach.

Wu Shuqing stated: Cold naturedly contracts and draws inward. Wind-Cold in the Taiyang meridian causing neck and back rigidity is a disease of the Taiyang sinews. Most formulas advocate Xuming Tang, following Zhang Zhongjing’s discussion. Guo’s approach, ignoring postpartum deficiency/excess and presence/absence of pathogen, blindly follows this method, which seems biased. Xue’s view, insisting on Shiquan Dabu Decoction (Ten Complete Tonic Decoction) due to massive blood loss, is another perspective. Meanwhile, *Yijian Zhi* records cures using Dadouzi Tang and Duhuo Tang, emphasizing wind treatment. Thus, Xuming Tang is not entirely baseless. However, the formula contains Mahuang (Ephedra Herb) and Fuzi (Aconite Root); it must not be used lightly in patients with dual Qi and Blood deficiency. Furthermore, Guo’s discussion advocates rapid administration, warning that delay leads to profuse sweating, yet he does not strictly forbid Mahuang. Is his reasoning sound? Both viewpoints should not be discarded but carefully considered during clinical practice.

Shen Zhai commented: The above eight passages describe the occurrence of Jing syndrome postpartum. Postpartum Jing syndrome is largely caused by blood deficiency. Therefore, the four passages below *Jin Gui* focus on excessive blood loss and should follow the treatment principles of Xue Lizhai and Miao Zhongchun. The last two passages analyze why Xuming Tang should not be used, to prevent misdiagnosis and serve as a warning.
