妊娠期间胎气上逆逼迫，严重时出现腹部胀满疼痛，这种病症称为“子悬”，紫苏饮是治疗此症的必用方药。这是因为紫苏饮专门用于治疗妊娠期胎气不和，导致浊气上举、胎气受热上逆，从而引起心胃部位胀满的症状。而且这类病症多伴有气机郁滞，适宜采用疏理气机、舒展郁结的方法；如果不使用紫苏、大腹皮、川芎、陈皮就无法流通气机，不使用当归、白芍就无法滋养血液，气血通畅后胎气自然下降。然而邪气聚集之处，正气必然虚弱，所以用人参、甘草来补益正气。大致来说，胎气上逆多属于火旺所致，应紧急使用黄芩、白术、香附之类的药物，不可服用过于寒凉的药物，否则反而会导致其他变证。我每次治疗孕妇心胃胀满，使用尊生和气饮效果显著。
子悬症表现为两尺脉象消失（绝），其余脉象平和，不可误认为是死胎。且死胎可以通过面色发青、舌质发青来辨别，适宜用紫苏饮治疗，这样胎气回归原位，胀满消除，脉象也会恢复。如果胎儿上逼心脏，呕吐剧烈欲死，紧急灌服童便即可缓解，或者取十枚乌梅肉研烂，加入生姜三片，煎汤灌服也能缓解，这是利用酸味来降敛气逆，兼用辛味来散除火气之逆。又有因坐草（临产准备）太早，心中恐惧，导致气机郁结不行，服用一剂紫苏饮即可分娩。
尊生和气饮：治疗孕妇心胃胀满。

妊娠期间吐血，凡是七情内伤或六淫外感，都足以导致失血的祸患。主要病机在于火热，因为气血壅盛以供养胎元，若有所感触，则气机上逆而火邪上乘，导致心烦闷乱，血液随之溢出，严重时甚至导致堕胎。但火邪有虚实之分，实火需清热养血；虚火需滋阴补水，这样血液才能安宁，胎元得以稳固。如果泛用行血、清血的药剂，胎元必定坠落，灾祸随即而至。
鼻衄不止，可用东垣的凉膈散，加入当归、生地各一钱，茅花一大团，生姜作为引经药。
咳嗽咳血，适宜使用凉血地黄汤。《医通》记载：咳嗽咯血，在妊娠期间都不宜出现，如果出现面赤声哑，属于不治之症。又说：凡是咯吐鲜血，多会导致堕胎，因为胎赖血养，不宜漏溢，适宜用紫苏饮加条芩（黄芩）。
尿血是由于热邪侵入血分，流渗于膀胱，所以尿液从尿道排出带血，若为胎漏（先兆流产出血），则血液从阴道排出，二者可以辨别。适宜用四物汤加山栀、发灰，或者阿胶、熟地、麦冬、五味子之类的药物。如果是怒动肝火，用小柴胡汤加山栀；脾气下陷及劳动导致的脾火，用补中益气汤加茯苓、车前子；若是浓味积热，用加味清胃散；若是肝脾血流不畅，用加味逍遥散。
肠风脏毒下血者，用平胃散去苍术，加槐角、防风、当归、乌梅治疗。

During pregnancy, if the fetal qi rebels and presses upward, causing severe abdominal distension and pain, this condition is termed "Zixuan" (Fetal Suspension). Zisu Yin (Perilla Decoction) is an essential prescription for treating it. This is because Zisu Yin specifically treats disharmony of fetal qi during pregnancy, where turbid qi rises and pushes the fetus upward, causing fetal heat and rebellious qi, leading to fullness and distension in the heart and stomach. Moreover, such conditions are mostly accompanied by Qi stagnation; it is appropriate to regulate Qi and relieve depression. Without Perillae Folium (Zisu), Tugong Fructus (Fupi), Chuanxiong Rhizome (Chuanxiong), and Tangerine Peel (Chenpi), Qi cannot flow freely; without Angelicae Sinensis Radix (Danggui) and Paeoniae Radix Alba (Baishao), Blood cannot be nourished. Once Qi and Blood are unobstructed, the fetal qi naturally descends. However, where pathogenic factors gather, Zheng Qi (Upright Qi) must be deficient; therefore, Ginseng Radix et Rhizoma (Renshen) and Glycyrrhizae Radix et Rhizoma Preparata (Zhigancao) are used to tonify deficiency. Generally, rebellious fetal qi belongs to excessive Fire; one should urgently use Scutellariae Radix (Huangqin), Atractylodis Macrocephalae Rhizoma (Baizhu), and Cyperi Rhizoma (Xiangfu), and must not administer overly cold medicines, lest they cause other complications. Whenever I treat pregnant women with heart and stomach distension, Zunsheng Heqi Yin (Harmonizing Qi Decoction for Respectful Life) yields excellent results.
The symptom of Zixuan presents with the absence of pulse at both Chi positions (Kidney pulses), while other pulses remain peaceful; it must not be mistaken for a dead fetus. A dead fetus can be distinguished by a bluish complexion and bluish tongue color. It is appropriate to treat it with Zisu Yin, after which the fetal qi returns to its original position, distension subsides, and the pulse reappears. If the fetus presses against the heart causing severe vomiting and retching, urgently administering child's urine (Tongbian) will provide relief. Alternatively, ten pieces of Mume Fructus flesh (Wumei Rou) can be mashed, mixed with three slices of Zingiberis Rhizoma Recens (Shengjiang), decocted in water, and administered orally. This utilizes the sour flavor to descend and astringe rebellious Qi, combined with the pungent flavor to disperse rebellious Fire Qi. In cases where labor preparation begins too early, causing fear and anxiety that leads to Qi knotting and stagnation, a single dose of Zisu Yin may induce delivery.
Zunsheng Heqi Yin: Treats heart and stomach distension in pregnant women.
Ren Shen (Ginseng Radix et Rhizoma), Su Geng (Perillae Caulis), Bai Shao (Paeoniae Radix Alba, stir-fried with wine), Chuan Xiong (Chuanxiong Rhizoma) — each 6 fen; Dang Gui (Angelicae Sinensis Radix) — 1 qian or 6 fen (washed with wine); Fu Pi (Tugong Fructus, processed and cleaned) — 5 fen; Mu Xiang (Aucklandiae Radix, ground and taken as juice) — 2 fen; Zhi Gan Cao (Glycyrrhizae Radix et Rhizoma Preparata) — 3 fen.
Hematemesis during pregnancy, whether caused by internal injury from the Seven Emotions or external invasion by the Six Excesses, is sufficient to cause hemorrhage. The primary pathogenesis involves Heat-Fire. Since Qi and Blood are abundant to nourish the fetal origin, any disturbance causes Qi to rebel and Fire to ascend, resulting in mental restlessness and chest oppression, with blood overflowing accordingly. In severe cases, this may lead to abortion. However, Fire has deficiency and excess types: Excess Fire requires clearing Heat and nourishing Blood; Deficient Fire requires nourishing Yin and supplementing Water, thereby stabilizing the blood and securing the fetus. If hemostatic or blood-cooling agents are indiscriminately used, the fetus will inevitably abort, and disaster will follow immediately.
Epistaxis that does not stop: Use Dongyuan's Liangge San (Cooling the Diaphragm Powder), adding Dang Gui (Angelicae Sinensis Radix) and Shu Di Huang (Rehmanniae Radix Preparata) each 1 qian, a large bunch of Mao Hua (Euphrasiae Herba or similar herb associated with stopping bleeding), and Sheng Jiang (Zingiberis Rhizoma Recens) as a guiding drug.
Cough with hemoptysis: Liangxue Dihuang Tang (Blood-Cooling Rehmannia Decoction) is appropriate. *Yitong* states: Cough with hemoptysis should not appear during pregnancy; if accompanied by red face and hoarse voice, it is incurable. It also states: Hemoptysis often leads to abortion, as the fetus relies on Blood for nourishment and leakage is unfavorable. It is appropriate to use Zisu Yin plus Tiao Qin (Scutellariae Radix/Huangqin).
Hematuria occurs when Heat invades the Blood level and seeps into the Bladder, causing blood to exit via the urethra. This can be distinguished from Taileu (threatened miscarriage bleeding), where blood exits via the vagina. Treatment is appropriate with Siwu Tang (Four Substances Decoction) added with Zhizi (Gardeniae Fructus) and Fa Hui (Hair Ash), or Ejiao (Colla Corii Asini), Shu Di Huang (Rehmanniae Radix Preparata), Maidong (Ophiopogonis Radix), and Wuweizi (Schisandrae Fructus). If anger stirs Liver Fire, use Xiaochaihu Tang (Minor Bupleurum Decoction) added with Zhizi; if Spleen Qi sinks or Labor-induced Spleen Fire arises, use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) added with Fuling (Poria) and Cheqianzi (Plantaginis Semen); if accumulated heat from rich flavors occurs, use Jiawei Qingwei San (Modified Clear Stomach Powder); if Liver and Spleen Blood flow is obstructed, use Jiawei Xiaoyao San (Modified Free and Easy Wanderer Powder).
For lower gastrointestinal bleeding due to Changfeng (Intestinal Wind) or Zhangdu (Visceral Toxin), use Pingwei San (Calm the Stomach Powder) minus Cangzhu (Atractylodis Rhizoma), added with Huaijiao (Gleditsiae Sinensis Fructus), Fangfeng (Saposhnikoviae Radix), Dang Gui (Angelicae Sinensis Radix), and Wumei (Mume Fructus).

Decoct in water. If wheezing is present, add Gualou Ren (Trichosanthis Semen) 1 qian.
