产后咳嗽，或因阴血耗损，或因肺气亏伤，或阴火上炎，或风寒所感。主治之法∶若阴血虚
者，用芎、归、熟地、参、术。肺气伤者，用四君、芎、归、桔梗。阴火上炎者，六味地黄
加参术。风寒所感者，补中益气加桔梗、紫苏。若瘀血入肺发喘，急用二味参苏饮，多有得
生者。若兼口鼻起黑，或鼻出血，急用前散，亦有得生者。然而，所患悉因胃气不足，盖胃
为五脏之根本，人身之根蒂，胃气一虚，五脏失所，百病生焉。但患者多谓腠理不密所致，
殊不知肺属辛金，生于己土，亦因土虚不能生金，而腠理不密，外邪所感。只阴火上炎亦壮
土，金生肾水以制火为善。若迳治其病，则误矣。

产后咳嗽，可能因为阴血耗损，也可能因为肺气亏伤，或者阴火上炎，或者是感受了风寒。治疗的主要方法：如果是阴血虚的，用川芎、当归、熟地黄、人参、白术。如果是肺气受伤的，用四君子汤加川芎、当归、桔梗。如果是阴火上炎的，用六味地黄丸加人参、白术。如果是感受风寒的，用补中益气汤加桔梗、紫苏。如果有瘀血进入肺部引发气喘，紧急使用二味参苏饮，大多能够存活。如果兼有口鼻出现黑色，或者鼻出血，紧急使用前散（指前文提到的方剂或特定急救方），也有能够存活的。然而，这些病症全是因为胃气不足引起的，因为胃是五脏的根本，人身的根基，胃气一旦虚弱，五脏失去滋养，各种疾病就会产生。但是患者多认为是腠理不密（毛孔疏松，卫外不固）导致的，却不知道肺属辛金，生于己土（脾土），也是因为土虚不能生金，导致腠理不密，从而感受外邪。只有阴火上炎也能壮实土气，金能生肾水以制约火气，这才是良策。如果径直治疗其病症（而不顾根本），那就错了。
治验案例：
一位产妇咳嗽声音沉重，鼻塞流涕，这是感受风寒所致，服用参苏饮一钟（量词，指一杯或一碗），症状立刻好转六七成，接着给予补中益气汤加桔梗、茯苓、半夏，一剂后痊愈，又给予六君子汤加黄芪，以巩固腠理而安养身体。
一位产妇早晨呕吐痰涎，傍晚发热，并且伴有失眠，泥古不化地采用清痰降火的方法，导致身体日渐消瘦，饮食日渐减少，前面的症状更加严重。我说：早晨吐痰，是脾气虚；夜间发热，是肝血虚；昼夜无法入睡，是脾血耗损。于是依次使用六君子汤、加味逍遥散、加味归脾汤进行调补，不到一个月就痊愈了。
一位产妇咳嗽痰多，面色发红，口干，内有热感且午后潮热，发作没有定时，这是阴火上炎，应当补益脾肾，于是使用补中益气汤、六味地黄丸而痊愈。
Cough after childbirth may be caused by the depletion of Yin and blood, damage to Lung Qi, flaming up of ministerial fire (Yin fire), or contraction of wind-cold. The primary treatment methods are as follows: For deficiency of Yin and blood, use Chuanxiong Rhizoma (Chuanxiong), Angelicae Sinensis Radix (Danggui), Prepared Rehmanniae Radix (Shudi), Ginseng Radix et Rhizoma (Renshen), and Atractylodis Macrocephalae Rhizoma (Baizhu). For damage to Lung Qi, use Sijunzi Tang (Four Gentlemen Decoction) with added Chuanxiong Rhizoma (Chuanxiong), Angelicae Sinensis Radix (Danggui), and Platycodonis Radix (Jiegeng). For flaming up of ministerial fire (Yin fire), use Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) with added Ginseng Radix et Rhizoma (Renshen) and Atractylodis Macrocephalae Rhizoma (Baizhu). For contraction of wind-cold, use Buzhong Yiqi Tang (Decoction for Boosting the Middle and Augmenting Qi) with added Platycodonis Radix (Jiegeng) and Perillae Folium (Zisu). If blood stasis enters the Lung causing wheezing, urgently administer Erwei Renshen Yin (Two-Ingredient Ginseng Infusion); many patients survive. If accompanied by black discoloration around the mouth and nose, or epistaxis, urgently administer Qiansan (Prior Powder); some patients survive. However, all these conditions stem from insufficiency of Stomach Qi, because the Stomach is the root of the five Zang organs and the foundation of the human body. Once Stomach Qi is deficient, the five Zang organs lose their nourishment, and myriad diseases arise. Patients often attribute this to loose interstices (Wei Qi failing to secure the exterior), not realizing that the Lung belongs to Xin Metal and is born from Ji Earth (Spleen Earth). It is precisely because Earth deficiency fails to generate Metal that the interstices become loose and susceptible to external pathogens. Only when ministerial fire (Yin fire) flares up can it strengthen Earth; subsequently, Metal generates Kidney Water to control Fire, which is the optimal approach. If one merely treats the symptoms directly without addressing the root, it is an error.
Case Records:
A postpartum woman suffered from cough with a heavy voice, nasal congestion, and runny nose, indicating contraction of wind-cold. After taking one dose of Renshen Yin (Ginseng Infusion), her symptoms improved significantly. She was then prescribed Buzhong Yiqi Tang (Decoction for Boosting the Middle and Augmenting Qi) with added Platycodonis Radix (Jiegeng), Poria (Fuling), and Pinelliae Rhizoma Preparatum (Banxia), recovering after one dose. Subsequently, she took Liujunzi Tang (Six Gentlemen Decoction) with added Astragali Radix (Huangqi) to consolidate the interstices and restore health.
A postpartum woman vomited phlegm in the morning, had fever in the evening, and suffered from insomnia. Adhering rigidly to methods of clearing phlegm and descending fire, her body grew thinner daily, her appetite decreased, and her previous symptoms worsened. I stated: Vomiting phlegm in the morning indicates Spleen Qi deficiency; fever at night indicates Liver Blood deficiency; inability to sleep day and night indicates consumption of Spleen Blood. Therefore, she was sequentially treated with Liujunzi Tang (Six Gentlemen Decoction), Jia Wei Xiaoyao San (Modified Free and Easy Wanderer Powder), and Jia Wei Guipi Tang (Modified Restore the Spleen Decoction), resulting in recovery within a month.
A postpartum woman presented with cough, copious sputum, flushed face, dry mouth, internal heat, afternoon tidal fever, and irregular episodes of heat. This indicated flaming up of ministerial fire (Yin fire). Treatment focused on tonifying the Spleen and Kidneys using Buzhong Yiqi Tang (Decoction for Boosting the Middle and Augmenting Qi) and Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia), leading to recovery.
A postpartum woman experienced cough, abdominal fullness, refusal to eat, excessive nasal discharge and saliva, facial edema, and rebellious Qi. This pathology originated in the Stomach and affected the Lung. She recovered after taking Yigong San (Extraordinary Assistance Powder).
