《金匮要略》曰∶产后中风发热，面正赤，喘而头痛，竹叶汤主之。
徐忠可曰∶中风，发热头痛，表邪也。然面正赤，所谓面若朱妆，乃真阳上浮，加之以喘，气高不下也。

《金匮要略》说：产妇出现郁冒（因血虚导致阳气厥逆，进而引起头晕目眩、神志昏蒙的病证），脉象微弱，只有头部出汗。之所以这样，是因为血虚导致厥逆，厥逆必然导致郁冒。郁冒病想要解除，必须全身大汗出。因为血虚导致下部厥逆，孤阳向上外越，所以只有头部出汗。因此产妇喜欢出汗的，是因为亡失阴血导致血虚，阳气独盛，所以应当通过汗出，使阴阳恢复平衡。
徐忠可说：产妇郁冒，虚证多而邪气少，所以脉象微弱，这是中气虚弱。体内正气虚弱，一身阴阳不和，所以身体无汗，只有头部出汗。为什么只有头部出汗呢？血虚导致下部厥逆，则下部的阴气耗尽，阳气成为孤阳，阳气孤立则向上外越而头部出汗。既然已经头部出汗，为什么仍然喜欢它出汗而病解呢？如果阴气没有亡失，则血未大虚；唯有产妇失血过多而亡阴，阳气才成为孤阳，与阴气相比，阳气为独盛，所以喜欢它出汗。损伤过盛的阳气以就合阴气，则阴阳平和，所以说阴阳乃复。
王海藏说：产妇头部出汗，只到颈部为止，额头部位偏多。因为额头是六条阳经交汇之处，是由于虚热熏蒸所致。
慎斋按语：以上四条，叙述了产后有汗出的病证。医经说：夺血者无汗。汗与血同类，产后失血过多，则阴不能维系阳气，阴虚而阳气无所依附，周身汗出不止，此为阴阳两虚，有亡阳的危险，属于危重证候。如果身体无汗，只有头部有汗，头为诸阳之会，阴血突然亡失，孤阳上越，阴虽然虚弱，但阳气尚且有余，此时阴不胜阳，所以头部出汗，额头偏多，心火上浮，逼迫阳气外越，急需补益其阴，并加入收敛阳气的药物，则病自然痊愈。所以产妇又喜欢头部出汗。
《金匮要略》说：产后中风发热，面色正红，气喘且头痛，用竹叶汤主治。
徐忠可说：中风，发热头痛，是表邪。然而面色正红，所谓面若朱妆，是真阳上浮，加上气喘，是气逆上高不下。明明白白是产后大虚，元气阳气不能自我固摄，又夹杂表邪，自然应该攻补兼施。所以用桂枝、甘草、防风、葛根、桔梗、生姜、大枣，清除在上部的邪气，竹叶清胆腑的热，用人参、附子培补元气，挽回欲脱的阳气。
The *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet) states: In postpartum women, Yu Mao (depression and dizziness caused by blood deficiency leading to Yang rebellion) occurs with a faint pulse, and sweating is confined only to the head. The reason for this is that blood deficiency leads to Jue (rebellion/cold extremities), and Jue inevitably leads to Mao (dizziness/confusion). For a patient suffering from Mao to recover, profuse sweating throughout the body must occur. Because blood deficiency causes rebellion in the lower part, the solitary Yang floats upward, hence sweating on the head. Therefore, postpartum women favor sweating because the loss of Yin blood leads to blood deficiency and excessive Yang; thus, sweating should occur to restore the balance of Yin and Yang.
Xu Zhongke stated: Postpartum Yu Mao involves much deficiency and little pathogenic factor, hence the pulse is faint due to deficiency of Middle Qi. Internal deficiency leads to disharmony of Yin and Yang in the whole body, so there is no sweating on the body, only on the head. Why is there sweating only on the head? Blood deficiency causes rebellion in the lower part, exhausting the Yin Qi below, leaving Yang as "solitary Yang." When Yang is solitary, it floats upward, causing sweating on the head. Since there is already head sweating, why is recovery favored through sweating? If Yin had not been lost, blood would not be severely deficient. Only when a postpartum woman loses too much blood and suffers from loss of Yin does Yang become solitary. Compared to Yin, Yang is excessively strong, hence the preference for sweating. By reducing excess Yang to align with Yin, Yin and Yang achieve equilibrium, hence it is said that they are restored.
Wang Haizang stated: Postpartum head sweating stops at the neck, with more sweat on the forehead. This is because the forehead is the meeting point of the six Yang meridians, and the sweating results from steaming by deficiency-heat.
Shen Zhai commented: The above four passages describe conditions of sweating after childbirth. The Classics state: "Those who lose blood do not sweat." Sweat and blood are of the same category. After childbirth, excessive blood loss means Yin cannot anchor Yang; Yin deficiency leaves Yang without attachment, resulting in continuous sweating over the whole body. This indicates deficiency of both Yin and Yang, carrying the risk of collapse of Yang, which is a critical condition. If there is no sweating on the body but only on the head, since the head is the meeting point of all Yang meridians, sudden loss of Yin blood causes solitary Yang to float upward. Although Yin is deficient, Yang remains relatively abundant. At this time, Yin cannot overcome Yang, hence sweating on the head, particularly on the forehead. Floating Heart Fire forces Yang outward. Urgent tonification of Yin, combined with herbs that astringe Yang, will naturally restore health. Thus, postpartum women also favor head sweating.
The *Jin Gui Yao Lue* states: Postpartum Wind Stroke with fever, bright red face, wheezing, and headache is primarily treated with Zhu Ye Tang (Bamboo Leaf Decoction).
Xu Zhongke stated: Wind Stroke with fever and headache indicates exterior pathogenic factors. However, a bright red face, described as "face like vermilion makeup," indicates floating True Yang. Accompanied by wheezing, where Qi rises high and does not descend, it clearly indicates severe deficiency after childbirth. Yuan Qi (Original Qi) and Yang cannot consolidate themselves, compounded by exterior pathogens. Therefore, simultaneous attack and tonification are appropriate. Thus, Gui Zhi (Cinnamon Twig), Gan Cao (Licorice Root), Fang Feng (Siler Root), Ge Gen (Kudzu Root), Jie Geng (Platycodon Root), Sheng Jiang (Fresh Ginger), and Da Zao (Jujube) are used to clear pathogens in the upper part; Zhu Ye (Bamboo Leaf) clears heat in the Gallbladder Fu-organ; while Ren Shen (Ginseng Root) and Fu Zi (Aconite Root) tonify Yuan Qi and rescue Yang that is about to collapse.
