安胎的方法，以养血气、调理脾胃为主。白术能补益脾气，从而培补万物之母（脾为后天之本）；黄芩（条芩）能固护中焦并清泻火气，能够滋养子宫之阴，使火气不妄动，因此被视为安胎的圣药。砂仁能安胎，是因为它具有止痛和行气的作用。过度劳累、精神紧张、发怒以及情欲之火，都能导致堕胎。推究其根本原因，都在于“热”。火能消蚀万物，这是自然规律。古代方书认为风冷伤害子宫而导致堕胎，这是没有通达病情本质的说法。
对于习惯性流产的妇女，如果中气不调、食欲减退，不必急于养血，应先调理脾胃，随后服用补中益气汤，使气血自然生成。如果是因母亲患病而扰动胎元，只需治疗母亲的疾病，胎元自然安定；如果是因胎元病变导致母亲患病，只需安胎，母亲的疾病自然痊愈。
胎儿多在怀孕三个月时流产，此时手厥阴心包络主管养育胎元。若劳心多虑，导致心包络虚弱，不能滋养胎元则会导致流产。治疗时应兼以制约火气，使用四物汤加黄柏、玄参、白术、黄芩。
若左脉微弱，伴有身体疼痛、夜间发热、腰痛、胎动不安，属于血虚证，使用四物汤加杜仲、黄芩、白术、秦艽。
若右脉寸关部大而无力，似滑但不流利，伴有倦怠、懒于言语动作，属于气虚证，使用补中益气汤加山药、杜仲、黄芩。
若两手脉象均弱，胎元常感下坠，属于气血两虚证，使用八珍汤加山栀、杜仲、续断、黄芩、白术。
孕妇突然腹痛，单用佛手散（由当归、川芎组成，方见《秘要》）煎服糯米汁送下。
孕妇阴道流出赤色汁液，属于血虚有火证，正治法使用子芩、当归、川芎煎服。若是急症或特殊情形，则使用银苎酒。
配方：苎麻根（去除黑皮，研碎，五钱），白银（一两）。以水和酒各半煎服。
The method for stabilizing the fetus primarily focuses on nourishing blood and qi, and regulating the Spleen and Stomach. Baizhu (Atractylodis Macrocephalae Rhizoma) tonifies Spleen Qi to cultivate the "Mother of All Things" (Spleen as the root of post-heaven existence); Tiaohuangqin (Scutellariae Radix) secures the Middle Jiao and drains Fire Qi, thereby nourishing the Yin of the uterus, preventing Fire from moving recklessly, thus regarded as a sacred herb for fetal stabilization. Amomi Fructus stabilizes the fetus due to its ability to relieve pain and promote Qi circulation. Overwork, mental strain, anger, and Fire arising from emotional desires can all induce abortion. Tracing to the root, all are caused by Heat. Fire consumes things; this is the natural order of creation. Ancient formulas claimed that Wind-Cold injuring the uterus causes abortion, which fails to understand the true nature of the disease.
For women with a history of habitual abortion, if there is dysfunction of Middle Qi and poor appetite, one need not prioritize nourishing blood; instead, first regulate the Spleen and Stomach, then administer Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) to allow Blood and Qi to generate naturally. If the fetus is disturbed due to the mother's illness, treat only the mother's illness, and the fetus will stabilize naturally. If the mother's illness arises due to fetal pathology, stabilize the fetus, and the mother's illness will heal itself.
Fetuses often abort around the third month. At this time, the Pericardium Meridian of Hand-Jueyin governs the nourishment of the fetal origin. Mental exertion and excessive worry cause deficiency in the Pericardium Meridian, which fails to nourish the fetus, leading to abortion. Treatment should simultaneously control Fire, using Siwu Tang (Four Substances Decoction) added with Huangbai (Phellodendri Cortex), Yuanshen (Scrophulariae Radix), Baizhu, and Tiaohuangqin.
If the left pulse is weak, accompanied by body pain, night fever, lower back pain, and fetal restlessness, it belongs to Blood Deficiency. Use Siwu Tang added with Duzhong (Eucommiae Cortex), Huangqin, Baizhu, and Qinjiao (Gentianae Radix et Rhizoma).
If the right pulse at the Cun and Guan positions is large but forceless, resembling Slippery but not smooth, accompanied by fatigue and reluctance to speak or move, it belongs to Qi Deficiency. Use Buzhong Yiqi Tang added with Shanyao (Dioscoreae Rhizoma), Duzhong, and Tiaohuangqin.
If pulses in both hands are weak, and the fetus frequently feels like falling, it belongs to Dual Deficiency of Qi and Blood. Use Bazhen Tang (Eight Treasures Decoction) added with Shanzhi (Gardeniae Fructus), Duzhong, Xuduan (Dipsaci Radix), Tiaohuangqin, and Baizhu.
If a pregnant woman suddenly experiences abdominal pain, use Foshou San (Buddha's Hand Powder, composed of Danggui and Chuanxiong, see *Mi Yao*) alone, decocted with sticky rice water.
If a pregnant woman passes red fluid, it belongs to Blood Deficiency with Fire. The standard treatment uses Zihuangqin (Scutellariae Radix), Danggui (Angelicae Sinensis Radix), and Chuanxiong (Chuanxiong Rhizoma) decocted and taken orally. In acute or special cases, use Yinzhu Jiu (Silver and Ramie Root Wine).
Formula: Zhugen (Boehmeriae Caulis et Folium, remove black skin and crush, 5 qian), Baiyin (Silver, 1 liang). Decoct with half water and half wine, then take orally.
Another method: Take Zhugen, about one chi long and as thick as a toe, decoct and take orally, and the condition will heal. Danxi stated that Zhugen can nourish Blood and resolve stagnation.
During pregnancy, one should nourish Blood, augment Qi, strengthen the Spleen, and clear Fire. One should commonly consume Gutai Yin (Stabilize Fetus Drink).
