单养贤说：产后出现气喘、呼吸急促，这是第一危险的证候。世人常常将其当作痰火实证来治疗，以讹传讹，应当使用人参生化汤进行加减治疗。人们大多怀疑人参会助长喘逆而不敢使用，导致很多患者因此无法救治。方中加入川芎、当归在内，万无一失。有人在使用人参时加入陈皮来制约其药性，反而导致正气耗散，这一点切不可相信。
慎斋按语：以上四条内容，叙述了产后出现气喘的证候。产后气喘，有虚证和实证的区分。如果是败血进入肺部，污血感受寒邪，这属于实证。可用参苏饮、夺命丹、血竭散等方剂攻下治疗而痊愈。如果是因失血过多，营血突然枯竭，卫气失去主宰，孤阳上浮，这属于血脱而气不归元（元气不能固摄）。非要用大剂量的人参生脉散，以及生化汤加入桂枝、附子才能治疗。如果错误地按照风痰、污血来治疗，是加速患者的死亡。观察立斋（薛己）治疗产后喘急的案例，他认为若是脾肺气弱，使用六君子汤；若是中气虚寒，使用补中益气汤加入干姜、桂枝。更有阳气虚脱，气喘急促、自汗、手足俱冷的情况，用大剂量的人参附子汤服用。这种论述确实抓住了根本。
《产宝百问》说：产后四肢浮肿，是由于败血乘虚停积，顺着经络流入四肢，停留日久，腐败坏乱如水液泛滥，所以导致面色发黄，四肢浮肿。医生不认识这个病机，就把它当作水气病（水肿）来治疗。凡是治疗水气病，多用导水利尿的药物。对于极度虚弱的产妇，本身已经虚弱，再用药物使其更虚，这叫重虚，多导致早亡。应服用小调经散，血液运行通畅则肿胀消退而痊愈。
陈无择说：产后浮肿原因多样，有的从怀孕时开始浮肿延续到产后不退。也有的是产后缺乏调养护理，外感寒暑风湿之邪，内因喜怒忧惊等情志刺激，导致血与气相互搏结，留滞于经络之中，气分和血分的病机不可不辨别，应当根据脉象和证候进行治疗，务必探求疾病的真情。小调经散治疗血分引起的浮肿固然有效，但药力浅薄难以依靠，不如吴茱汤、枳术汤、夺魂散、大调经散，这些都是重要的药物。
Dan Yangxian stated: Postpartum asthma with rapid breathing is the most critical syndrome. The world often treats it as an excess syndrome of phlegm-fire, passing on errors from generation to generation; it should be treated with modifications of Rensheng Huasheng Decoction (Ginseng and Blood-Generating Decoction). Many people suspect that Ren Shen (Ginseng) can exacerbate asthma and thus do not use it, leading to many untreatable cases. Including Xiong Gui (Ligusticum Chuanxiong Rhizome and Angelica Sinensis Radix) in the formula ensures no mistakes. Using Chen Pi (Tangerine Peel) to restrain Ren Shen (Ginseng) instead causes dispersion of vital energy; this must not be believed.
Shenzhai commented: The above four items describe the syndrome of postpartum asthma. Postpartum asthma has distinctions between deficiency and excess syndromes. If敗血 (stagnant blood) enters the lungs, or污血 (filthy blood) contracts cold, this belongs to excess syndromes. It can be cured by purging with Shensu Yin (Ginseng and Perilla Leaf Decoction), Xueming Dan (Life-Taking Pill), or Xuejie San (Dragon's Blood Powder). If excessive blood loss occurs, causing sudden exhaustion of Ying Blood (Nutritive Blood), and Wei Qi (Defensive Qi) loses its master, with lone Yang floating upward, this is a case of blood depletion where Qi fails to return to its origin. Only large doses of Rensheng Maimai San (Ginseng and Pulse-Nourishing Powder) combined with Huasheng Tang (Blood-Generating Decoction) added with Guizhi (Cinnamon Twig) and Fuzi (Prepared Aconite Root) can treat it. Mistakenly treating it as wind-phlegm or filthy blood accelerates death. Observing Lizhai (Xue Ji)'s treatment of postpartum urgent asthma, he stated that if Spleen and Lung Qi are weak, Liujunzi Tang (Six Gentlemen Decoction) should be used; if Middle Qi is deficient and cold, Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) added with Jiang (Dried Ginger) and Gui (Cinnamon) should be used. Furthermore, in cases of Yang Qi deficiency and collapse, with urgent asthma, spontaneous sweating, and cold hands and feet, large doses of Shenfu Tang (Ginseng and Aconite Decoction) should be administered. This discussion indeed grasps the root cause.
"Baobao Baiwen" (Hundred Questions on Obstetric Treasures) states: Postpartum edema of the four limbs is caused by stagnant blood taking advantage of deficiency to accumulate, flowing along the meridians into the limbs, lingering for a long time, becoming corrupt and spreading like water, thus causing yellow complexion and edema of the four limbs. Physicians who do not recognize this condition treat it as Shuiqi (Water Qi/Edema). Treatments for Shuiqi (Water Qi/Edema) mostly use drugs that guide out water (diuretics). For extremely deficient postpartum women, who are already deficient, using such drugs further depletes them, which is called "double deficiency," often leading to premature death. One should administer Xiaotiaojing San (Small Menstrual Regulating Powder); when blood circulation resumes, the swelling subsides, and recovery occurs.
Chen Wuyue stated: Postpartum edema has various causes. Some women experience edema starting during pregnancy that does not resolve after childbirth. Others fail to care for themselves properly after childbirth, contracting external Cold, Heat, Summerheat, and Damp-Wind pathogens, while internally suffering from emotional disturbances such as anger, joy, worry, and fright. This causes Blood and Qi to contend and stagnate in the collaterals. The differentiation between Qi aspect and Blood aspect cannot be neglected; treatment should follow the pulse and symptoms to ascertain the true nature of the disease. Xiaotiaojing San (Small Menstrual Regulating Powder) is effective for Blood aspect edema, but its power is shallow and unreliable. It is inferior to Wu Zhu Yu Tang (Evodia Decoction), Zhizhu Tang (Aurantium and Atractylodes Macrocephala Decoction), Duohun San (Soul-Seizing Powder), and Datiaojing San (Large Menstrual Regulating Powder), all of which are essential medicines.
