人之胃腑，为水谷之海，而水谷之精，化为血气，荣润脏腑。产后劳伤脏腑，寒邪易乘，入于肠胃，则
气逆呕吐而不食也。初产，宜加减生化汤。七日外，宜温胃丁香散。如咳嗽、呕逆、怔忡、目眩，用石莲散。
《秘书》云∶产后胃气不和，呕吐不止，全不纳谷，初产香砂生化汤。块痛止，加味香砂生化汤。又云∶当
分二证，立三方。如七日内块痛未除，当重块，安胃行血汤佐以温胃药。如七日内曾服生化汤三四帖，血
块不痛，呕不纳谷，当服加减六和汤，又和中汤，此二方选用。如产后呕止，或服三方而胃和呕止痛止，但
血气不足食少，宜补中和胃汤。冯氏仿立斋治法云∶饮食过多，六君子加楂、曲。兼劳役，补中汤。饮食停滞，
人参养胃汤。脾胃气虚，六君子。胃气虚寒，加炮姜、煨木香。寒水侮土，益黄散。肝木侮土，六君子加升、
柴。呕吐泄泻，手足俱冷，肚腹作痛，乃阳气虚寒，急用附子理中汤。
此内有命门火衰，不能生土而呕吐，用八味丸一论，恐非救急之务，故摘出。密斋遵郭稽中治云∶有败血散
于脾胃，脾受则不能运化津液而成腹胀，胃受则不能受水谷而生呕逆。若以寻常治胀呕之剂，则药不对证，
反增其病，用抵圣汤。若产后伤食，呕吐胀满，用六君子汤为主，加随证药治之。予谓冯氏偏于补气，
密斋用抵圣一论，泥于败血，临证者，似宜斟酌。一产妇朝吐痰，夜发热，昼夜无寐，或用清痰降火，
肌体日瘦，饮食日少，前证愈甚。盖早间吐痰，脾气虚也。夜间发热，肝血虚也。昼夜无寐，脾血耗也。遂
用六君子汤，加味逍遥散，加味归脾汤，以次调理而痊。

六君子汤 补中益气汤 人参养胃汤（俱见上卷诸痛门。） 附子理中汤（见上卷疟门，附枳
实理中汤下。）
人的胃腑，是受纳水谷的仓库，水谷的精微物质转化为血气，以此滋养润泽脏腑。产后因劳累损伤脏腑，寒邪容易趁虚而入，侵入肠胃，就会导致气机上逆、呕吐且无法进食。刚生产完时，适宜使用加减生化汤。七日后，适宜使用温胃丁香散。如果出现咳嗽、呕逆、心悸（怔忡）、头晕目眩等症状，则使用石莲散。
《秘书》记载：产后胃气不和，呕吐不止，完全不能进食，初产时使用香砂生化汤。如果瘀血块引起的疼痛停止，改用加味香砂生化汤。又记载：应当分为两种证候，设立三个方剂。如果在七日内瘀血块疼痛未消除，应当重用化瘀安胃、行血的药物，使用安胃行血汤，并佐以温胃的药物。如果在七日内已经服用过三四帖生化汤，但血块不痛，仍然呕吐且不能进食，应当服用加减六和汤或和中汤，这两个方剂可根据情况选用。如果产后呕吐停止，或者服用了上述三方后胃气调和、呕吐停止、瘀血块疼痛也停止，只是气血不足导致食欲减退，适宜使用补中和胃汤。
冯氏模仿薛立斋的治疗方法说：饮食过多，用六君子汤加山楂、神曲；兼有劳役过度，用补中益气汤；饮食停滞，用人参养胃汤；脾胃气虚，用六君子汤；胃气虚寒，加炮姜、煨木香；寒水之气反侮脾土，用益黄散；肝木之气反侮脾土，用六君子汤加升麻、柴胡；呕吐泄泻，手足冰冷，肚腹作痛，这是阳气虚寒，急需用附子理中汤。
其中关于命门火衰，不能生助脾土而导致呕吐的论述，引用了八味丸的理论，但这恐怕不是急救时的首要任务，所以将其摘除。密斋遵循郭稽中的治疗观点说：如果有败血（恶露）散乱于脾胃，脾受到侵害则不能运化津液而形成腹胀，胃受到侵害则不能受纳水谷而产生呕逆。如果用通常治疗腹胀呕吐的药物，则药不对症，反而加重病情，应使用抵圣汤。如果是产后伤食，出现呕吐胀满，以六君子汤为主，根据症状加减药物治疗。我认为冯氏偏重于补气，密斋使用抵圣汤的理论，拘泥于败血这一因素，临床医生似乎应当斟酌权衡。
有一位产妇早晨吐痰，夜间发热，昼夜无法入睡，有人使用清化痰热、降火的药物，导致身体日渐消瘦，饮食日益减少，前面的症状更加严重。这是因为早间吐痰是脾气虚弱所致；夜间发热是肝血虚弱所致；昼夜无法入睡是脾血耗损所致。于是使用六君子汤、加味逍遥散、加味归脾汤，依次调理而痊愈。

陈皮（一两） 青皮 诃子肉（煨） 炙甘草（各五钱） 丁香（二钱）
以上研为散剂，每次服用二三钱，加水煎服。或用黑糖调服一钱。益黄散不用补益中焦的方法，反而用青皮、橘皮这两味药来辟除陈积之气，其用意最为精微。此方原本是为婴儿久泻连绵不断，乳食积滞于内而设，所以需要这两皮专门调理肝脾的陈旧积滞，同时兼用诃子来兜涩下脱之气，丁香来温理中焦，甘草来调和脾气，深得在泻法中寓含补法的奥妙，如果不透彻理解这一义理，很难与之谈论最高明的治疗境界。
抵圣汤：治疗产后败血积于脾胃，腹胀呕逆。
人参 制半夏 泽兰 陈皮 赤芍（各二钱） 炙甘草（一钱）
用火焙干生姜三片，加水煎服。恶露过多者，去掉泽兰、赤芍，加倍增加陈皮、生姜用量。我认为陈皮用二钱过多，用一钱就足够了。
The human stomach is the sea of water and grain; the essence derived from water and grain transforms into blood and qi, nourishing and moistening the zang-fu organs. Postpartum, labor and fatigue damage the zang-fu organs, making them susceptible to invasion by cold pathogens. Once these pathogens enter the intestines and stomach, they cause rebellious qi, vomiting, and an inability to eat. Immediately after childbirth, Jiajian Shenghua Tang (Modified Birth-Invigorating Decoction) is appropriate. After seven days, Wenwei Dingxiang San (Stomach-Warming Clove Powder) is appropriate. If symptoms such as cough, retching, palpitations (Zhengchong), and dizziness occur, Shilian San (Stone Lotus Seed Powder) should be used.
The *Mishu* records: "When postpartum stomach qi is disharmonious, with incessant vomiting and complete inability to accept food, Xiangsha Shenghua Tang (Aucklandia and Amomum Birth-Invigorating Decoction) is used for initial postpartum cases. Once blood stasis pain ceases, Jiawei Xiangsha Shenghua Tang (Augmented Aucklandia and Amomum Birth-Invigorating Decoction) is used." It further states: "Two syndromes should be distinguished, and three formulas established. If within seven days the blood stasis pain remains, heavy emphasis should be placed on resolving stasis and calming the stomach using Anwei Xingxue Tang (Stomach-Calming and Blood-Circulating Decoction), assisted by stomach-warming herbs. If within seven days, three or four doses of Shenghua Tang have been taken, but the blood stasis does not hurt and vomiting/inability to eat persists, Jiahuan Liuhe Tang (Modified Six-Harmony Decoction) or Hezhong Tang (Middle-Harmonizing Decoction) should be administered, selecting one of these two formulas. If postpartum vomiting stops, or if after taking the aforementioned three formulas the stomach harmonizes, vomiting stops, and stasis pain ceases, but there is insufficient blood and qi leading to poor appetite, Buzhong Hewei Tang (Tonify-Middle and Harmonize-Stomach Decoction) is appropriate."
Feng Shi imitated the treatment methods of Xue Lizhai: For excessive food intake, use Liujunzi Tang (Six-Gentlemen Decoction) with Hawthorn (Shanzha) and Medicated Leaven (Qu). For cases complicated by overwork, use Buzhong Yiqi Tang (Tonify-the-Middle and Boost-Qi Decoction). For food stagnation, use Renshen Yangwei Tang (Ginseng Stomach-Nourishing Decoction). For spleen and stomach qi deficiency, use Liujunzi Tang. For stomach qi deficiency and cold, add Paojiang (Prepared Ginger) and Weimu Xiang (Baked Costus Root). When cold water insults earth (spleen), use Yihuang San (Benefit Yellow Powder). When liver wood insults earth, use Liujunzi Tang with Shengma (Cimicifugae Rhizoma) and Chaihu (Bupleuri Radix). For vomiting and diarrhea with cold extremities and abdominal pain, indicating yang qi deficiency and cold, Fuzi Lizhong Tang (Aconite Regulate-the-Middle Decoction) must be used urgently.
Regarding the theory that failure of the Mingmen fire (Gate of Life) to generate earth causes vomiting, the reference to Bawei Wan (Eight-Ingredient Pill) is excluded here, as it is likely not a matter for emergency rescue. Miyi Zhai followed Guo Jizhong’s treatment view: If lochia (bainxue) scatters into the spleen and stomach, the spleen suffers and cannot transform fluids, leading to abdominal distension; the stomach suffers and cannot receive water and grain, leading to vomiting and retching. Using ordinary remedies for distension and vomiting will mismatch the syndrome and worsen the condition; instead, Disheng Tang (Respect-Sage Decoction) should be used. If postpartum food injury causes vomiting and distension, Liujunzi Tang (Six-Gentlemen Decoction) should be the primary formula, modified according to symptoms. I consider Feng Shi’s approach biased toward tonifying qi, while Miyi Zhai’s reliance on Disheng Tang is too rigidly focused on blood stasis; clinicians should exercise discretion.
Consider a puerpera who vomited phlegm in the morning, had fever at night, and could not sleep day or night. Someone used herbs to clear phlegm and descend fire, resulting in daily emaciation, reduced food intake, and worsening of previous symptoms. The morning phlegm vomiting indicates spleen qi deficiency. The night fever indicates liver blood deficiency. The day-and-night insomnia indicates consumption of spleen blood. Subsequently, Liujunzi Tang (Six-Gentlemen Decoction), Jiawei Xiaoyao San (Augmented Free and Easy Wanderer Powder), and Jiawei Guipi Tang (Augmented Heart-Spleen Tonifying Decoction) were used sequentially for regulation, leading to recovery.

One slice of fresh ginger, decocted in water and taken orally. Remove Dingxiang when vomiting stops. If affected by cold, add Wuyu (Evodiae Fructus) 1-2 fen.
Buzhong Hewei Tang (Tonify-Middle and Harmonize-Stomach Decoction): Treats postpartum vomiting where, after taking the first three formulas, the stomach harmonizes, vomiting stops, and stasis pain ceases, but there is insufficient blood and qi leading to poor appetite.
Renshen (Ginseng Radix et Rhizoma) Baizhu (Atractylodis Macrocephalae Rhizoma, soil-fried) Danggui (Angelicae Sinensis Radix) BianDou (Lablab Album Semen, each 2 qian) Fuling (Poria, 1 qian) Shanyao (Dioscoreae Rhizoma, 1.5 qian) Paojiang (Prepared Ginger) Chenpi (Citri Reticulatae Pericarpium) Zhigancao (Honey-fried Licorice, each 4 fen).

Grind into powder, take 2-3 qian per dose, decocted in water. Alternatively, mix with black sugar and take 1 qian. Yihuang San does not use tonification of the middle jiao; instead, it uses Qingpi and Ju Pi (orange peels) to dispel stale qi, a subtle intent. This formula was originally designed for infants with chronic diarrhea due to milk and food stagnation internally. Thus, the two peels specifically regulate liver and spleen old accumulations, combined with Hezi to secure downward leakage, Dingxiang to warm and regulate the middle jiao, and Gancao to harmonize spleen qi. It deeply embodies the method of embedding tonification within purgation. Without thorough understanding of this principle, one cannot discuss supreme treatment.
Disheng Tang (Respect-Sage Decoction): Treats postpartum accumulation of lochia in the spleen and stomach, causing abdominal distension and vomiting/retching.
Renshen (Ginseng Radix et Rhizoma) Zhixia (Pinelliae Tuber prepared) Zelan (Leonuri Herba) Chenpi (Citri Reticulatae Pericarpium) Chishao (Paeoniae Radix Rubra, each 2 qian) Zhigancao (Honey-fried Licorice, 1 qian).
Three slices of ginger baked over fire, decocted in water and taken orally. If lochia discharge is excessive, remove Zelan and Chishao, and double the dosage of Chenpi and Shengjiang. I consider 2 qian of Chenpi excessive; 1 qian is sufficient.
