妊娠腹痛名胞阻，须审心腹少腹间，伤食心胃胎腰腹，少腹胞寒水尿难。
【注】孕妇腹痛，名为胞阻。须审其痛，或上在心腹之间者，多属食滞作痛；或下在腰腹
之间者，多属胎气不安作痛；若在少腹之间者，则必因胞血受寒，或停水尿难作痛也。
加味平胃散 延胡四物汤
心胃痛多伤食滞，苍朴陈甘果枳曲，便秘加军倍甘草，胎动延胡四物宜。
【注】孕妇心胃作痛者，多因伤食停滞。宜平胃散，即陈皮、浓朴、苍术、甘草也，加
草果、枳壳、神曲以消之。若更大便秘结，日久则加硝、黄以攻之，然必倍甘草以缓其峻
性，庶不伤胎。若腰腹作痛，胎动下血，则当用四物汤，君以延胡，以定痛而保胎也。

加味芎归饮 导赤散 五苓散
胞血受寒少腹疼，参吴胶艾草归芎。尿涩热甚导赤散，木通生地甘草灵。水盛阳虚五苓效，术
泽肉桂茯猪苓。
【注】少腹作痛者，乃胞中之血受寒也。宜加味芎归饮温之，其方即人参、吴茱萸、阿
胶、蕲艾、炙甘草、当归、川芎也。若因尿涩而痛，则是膀胱水病热甚，则以导赤散清

妊娠期间出现腹痛，称为“胞阻”，必须仔细辨别疼痛是在心腹部还是少腹部。若疼痛位于心胃部位，多因饮食停滞所致；若疼痛涉及腰部及腹部，多因胎气不安引起；若疼痛局限于少腹部，则必定是因为胞宫血液受寒，或是水湿停聚导致小便困难而引发的疼痛。
【注】孕妇出现腹痛，名为胞阻。必须审察其疼痛部位：如果疼痛在上部的心腹之间，大多属于食积停滞引起的疼痛；如果疼痛在下部的腰腹之间，大多属于胎气不安引起的疼痛；如果在少腹之间疼痛，则一定是因为胞血受寒，或者水湿停留、小便困难引起的疼痛。
加味平胃散、延胡四物汤
心胃部疼痛多由伤食停滞引起，可用苍术、厚朴、陈皮、甘草、枳壳、神曲等药（即加味平胃散）；若伴有便秘，加大黄并加倍使用甘草；若有胎动不安，宜用延胡四物汤。
【注】孕妇心胃部作痛，多因饮食停滞。适宜使用平胃散，即陈皮、厚朴、苍术、甘草，再加草果、枳壳、神曲以消导积滞。如果大便严重秘结，日久不愈，可加入芒硝、大黄以攻下，但必须加倍使用甘草以缓和其峻烈之性，从而不伤害胎儿。如果腰部及腹部作痛，伴有胎动下血，则应当使用四物汤，以延胡索为君药，以止痛并安胎。
四物汤（方剂见首卷）
加味胶艾四物汤、蜜硝汤
腹部及腰部剧烈疼痛需防止流产，可用胶艾四物汤加杜仲、大豆淋酒、葱白；若因外感邪气适宜加羌活、独活；若因内热便秘，用蜂蜜、芒硝攻下。
【注】胞系于腰部。凡是腹部和腰部疼痛的，必须防止流产。适宜使用胶艾四物汤，加入杜仲、大豆淋酒、葱白以定痛安胎。如果是因为外感风寒邪气，则加入羌活、独活以疏散邪气；如果是内热、大小便闭塞，则使用蜂蜜、芒硝煎汤以攻下。正如经典所说：“有故无殒”（有病则病受之，不会伤害母体）。
胶艾四物汤（方剂见首卷）
加味芎归饮、导赤散、五苓散
胞血受寒导致少腹疼痛，用人参、吴茱萸、阿胶、艾叶、甘草、当归、川芎（即加味芎归饮）；若小便涩痛且热象明显，用导赤散（木通、生地、甘草）；若水湿盛而阳气虚，五苓散有效（白术、泽泻、肉桂、茯苓、猪苓）。
【注】少腹作痛，是胞中的血液受寒所致。适宜使用加味芎归饮来温煦，该方即人参、吴茱萸、阿胶、蕲艾、炙甘草、当归、川芎。如果是因为小便涩滞而痛，这是膀胱水液代谢异常且热势较重，则用导赤散清热利湿，该方即生地、木通、甘草。如果水湿过盛且肾阳虚不能气化，则用五苓散渗湿利水，该方即茯苓、白术、泽泻、猪苓、肉桂。
Abdominal pain during pregnancy is termed "Bao Zu" (Placental Obstruction), and it is necessary to carefully distinguish whether the pain is located in the epigastrium/abdomen or the hypogastrium. Pain in the heart and stomach region is mostly due to food stagnation; pain involving the lower back and abdomen is mostly due to fetal unrest; pain confined to the hypogastrium is necessarily caused by cold invading the blood of the uterus, or by fluid retention leading to difficult urination.
[Note] Abdominal pain in pregnant women is named Bao Zu. One must examine the location of the pain: if the pain is in the upper area between the heart and abdomen, it mostly belongs to pain caused by food stagnation; if the pain is in the lower area between the waist and abdomen, it mostly belongs to pain caused by fetal unrest; if the pain is in the hypogastrium, it is definitely due to cold affecting the uterine blood, or pain caused by fluid accumulation and difficult urination.
Jiawei Pingwei San (Modified Pingwei Powder) and Yanhu Siwu Tang (Yanhusuo Four Substances Decoction)
Pain in the heart and stomach region is mostly caused by food stagnation; use Cangzhu, Houpo, Chenpi, Gancao, Zhike, Shenqu (i.e., Jiawei Pingwei San); if accompanied by constipation, add Jun (Dahuang/Rhubarb) and double the dosage of Gancao; if there is fetal movement, Yanhu Siwu Tang is suitable.
[Note] Heart and stomach pain in pregnant women is mostly due to food stagnation. It is appropriate to use Pingwei San, which consists of Chenpi, Houpo, Cangzhu, and Gancao, plus Caoguo, Zhike, and Shenqu to resolve stagnation. If stool is severely constipated for a long time, Mangxiao (Natrii Sulfas) and Huanglian (actually Huangqin/Huangbo? Context implies Dahuang/Mangxiao for purging, text says Xiao, Huang - likely Mangxiao and Dahuang) can be added to purge, but Gancao must be doubled to moderate its harsh nature, thereby not harming the fetus. If there is pain in the waist and abdomen with fetal movement and bleeding, Siwu Tang (Four Substances Decoction) should be used, with Yanhusuo as the sovereign herb, to relieve pain and secure the fetus.
Siwu Tang (Formula seen in Volume 1)
Jiawei Jiao'ai Siwu Tang (Modified Jiao'ai Four Substances Decoction) and Mixiao Tang (Honey and Mangxiao Decoction)
Severe abdominal and lumbar pain requires prevention of miscarriage; use Jiao'ai Siwu Tang plus Duzhong, Daoudou Linjiu (Soybean soaked wine), and Congbai (Scallion white); if due to external pathogenic factors, add Qianghuo and Duhuo; if due to internal heat and constipation, use Honey and Mangxiao to purge.
[Note] The placenta is attached to the waist. Whenever there is abdominal and lumbar pain, one must guard against miscarriage. It is appropriate to use Jiao'ai Siwu Tang, adding Duzhong, Daoudou Linjiu, and Congbai to stabilize pain and secure the fetus. If it is due to external invasion of Wind-Cold pathogens, then add Qianghuo and Duhuo to disperse them; if there is internal heat and closure of both large and small bowels, then use Honey and Mangxiao decocted in water to purge. As the classics say: "Yougu Wuyun" (When there is an existing pathology, the medicine will target the pathology without injuring the mother).
Jiao'ai Siwu Tang (Formula seen in Volume 1)
Jiawei Xionggui Yin (Modified Xiongui Drink), Daochi San (Guide Out Red Powder), and Wuling San (Five-Ingredient Powder with Poria)
Cold invading the uterine blood causes hypogastric pain; use Renshen, Wuzhuyu, Ejiao, Aye, Zhigancao, Danggui, Chuanxiong (i.e., Jiawei Xionggui Yin); if urine is涩 (astringent/difficult) and pain is severe with heat, use Daochi San (Mutong, Shengdi, Gancao); if water abundance and Yang deficiency prevail, Wuling San is effective (Baizhu, Zexie, Rougui, Fuling, Zhuling).
[Note] Pain in the hypogastrium indicates that the blood in the uterus has been affected by cold. It is appropriate to use Jiawei Xionggui Yin to warm it; this formula consists of Renshen, Wuzhuyu, Ejiao, Qi Ai, Zhigancao, Danggui, and Chuanxiong. If the pain is due to difficult urination, this is a disorder of bladder water metabolism with severe heat, so use Daochi San to clear heat and promote diuresis; this formula consists of Shengdi, Mutong, and Gancao. If water abundance and Kidney Yang deficiency prevent transformation, use Wuling San to leach out dampness; this formula consists of Fuling, Baizhu, Zexie, Zhuling, and Rougui.
