怀孕期间，必须防范在妊娠第三、第五和第七个月发生流产。因为怀孕三个月时，胎火初动，常导致心烦意乱、胸闷不适。第四、五个月时，受少阴君火滋养精气。第六、七个月时，受少阳相火滋养元气。如果体质气血稍有不足，就会导致胎坠。巢元方说：受孕后在腹中，每七天变化一次，到三个月时归属心，五个月时归属脾，七个月时归属肺，都归属于五脏。脏阴亏损就容易流产。比如第一个月归属肝，发怒就会导致流产。每次清洗下身，窍孔张开也会导致流产。房事不慎，也会导致流产。就是前文所说的随受孕随即坠落的情况，大半都是这样，人们往往察觉不到。大凡胎气，腹痛是常事，而腰痛则必须特别防范。应当立即服药，补肾安胎，不能不早作说明。一旦见红出血，只能十保其三，适宜服用安胎饮，重用熟地黄，或者加入人参、桑寄生。但是小产比大产更严重。因为大产如同瓜熟蒂落，是天生自然的过程。小产必然有其原因，因惊动而下坠，犹如生生折断其蒂。胎儿的胞宫附着于带脉，带脉又环绕系结于腰部，所以腰痛带脉松弛，胞胎就会下坠。预先服用保胎丸，就没有祸患了。
小产后，治疗即与大产相似。如果失血较多，即可服用人参、熟地黄，而当归宜重用，这也是去瘀生新的意思。如果有严重的虚寒症状，适宜加入附子、阿胶。
子烦症，表现为心烦意乱、胸闷，难以言说的痛苦，这是因为君火与相火聚集以养胎，火盛内热导致烦躁，适宜用淡竹叶汤主治。如果是气滞痰凝导致的胸闷，使用二陈汤加入白术、黄芩、苏梗、枳壳。如果是脾虚胃弱，食少呕吐者，使用六君子汤，或者加入香附、砂仁来安抚调理。但是子烦之症，如果不善于调养摄护，就会导致胎动不安，须防范小产的祸患。又有呕吐日久导致气逆，胃气元气大虚，不能进食，恐怕导致产妇气脱，所以初期要降火，随后要安胃进食，这是一定的法则。

二陈汤（见前恶阻章节）
六君子汤（同见前）
During pregnancy, one must guard against miscarriage occurring in the third, fifth, and seventh months. This is because at three months of gestation, fetal fire begins to stir, often causing mental restlessness and chest oppression. At four or five months, the body receives the Ministerial Fire of Shaoyin (Lesser Yang) to nourish essence. At six or seven months, it receives the Executive Fire of Shaoyang (Greater Yang) to nourish qi. If the constitution has even slight deficiency of qi and blood, the fetus may descend and be lost. Chao Yuanfang stated: After conception in the abdomen, changes occur every seven days; by the third month, it belongs to the Heart; by the fifth month, to the Spleen; by the seventh month, to the Lung; all belonging to the Zang organs. Deficiency of Yin in the Zang organs makes miscarriage easy. For instance, if the first month belongs to the Liver, anger can cause miscarriage. Washing the lower body causes the orifices to open, which can also lead to miscarriage. Imprudent sexual intercourse can also cause miscarriage. This is what was previously referred to as "miscarrying immediately upon conception," which happens in most cases, though people are often unaware. Generally, abdominal pain due to fetal qi is common, but lower back pain requires strict vigilance. Medication should be taken immediately to tonify the Kidney and calm the fetus; this advice cannot be given too early. Once bleeding occurs, only three out of ten cases can be saved; it is appropriate to take Antai Yin (Calming Fetus Decoction), using a heavy dose of Shu Di Huang (Prepared Rehmannia Root), or adding Ren Shen (Ginseng Root) and Sang Ji Sheng (Taxillus Branch). However, spontaneous abortion (Xiao Chan) is more severe than term delivery. Term delivery is like a ripe melon falling from the vine, a natural process of heaven. Spontaneous abortion must have a cause; it descends due to disturbance, akin to forcibly breaking the stem. The fetal sac attaches to the Dai Mai (Belt Vessel), which encircles and ties to the waist; therefore, when there is lower back pain and the Dai Mai becomes lax, the fetal sac will descend. Taking Baotai Wan (Fetus-Protecting Pills) in advance prevents disaster.
After spontaneous abortion, treatment is similar to that for term delivery. If blood loss is significant, Ren Shen (Ginseng Root) and Shu Di Huang (Prepared Rehmannia Root) can be taken, while Dang Gui (Angelica Sinensis Root) should be used in heavy doses, reflecting the principle of removing stasis to generate new blood. In cases of severe deficiency-cold, Fu Zi (Aconite Lateral Root) and E Jiao (Donkey-hide Gelatin) should be added.
Zi Fan Syndrome (Pregnancy-related Restlessness) presents with mental restlessness, chest oppression, and indescribable distress. This is caused by the gathering of Ministerial Fire and Executive Fire to nourish the fetus; excessive fire leads to internal heat and restlessness. Dan Zhu Ye Tang (Lophatherum Decoction) is indicated as the primary treatment. If chest oppression is due to Qi stagnation and phlegm coagulation, Er Chen Tang (Two-Cured Decoction) with Bai Zhu (Atractylodes Macrocephala Rhizome), Huang Qin (Scutellaria Root), Su Geng (Perilla Stem), and Zhi Qiao (Aurantium Fructus) should be used. If there is Spleen deficiency and Stomach weakness with poor appetite and vomiting, Liu Jun Zi Tang (Six-Gentlemen Decoction) should be used, or Xiang Sha Liu Jun Zi Tang (Aucklandia and Amomum Six-Gentlemen Decoction) added to soothe the condition. However, if Zi Fan syndrome is not properly managed, it can lead to restless fetus and risk of spontaneous abortion. Furthermore, prolonged vomiting may cause Qi rebellion and severe depletion of Stomach Yuan Qi, preventing food intake, which risks Qi collapse in the mother. Therefore, the initial approach must be to clear fire, followed by calming the Stomach and promoting food intake; this is a fixed principle.

Liu Jun Zi Tang (Six-Gentlemen Decoction) (Same as seen previously)
If Xiang Fu (Cyperi Rhizoma, 1 qian) and Sha Ren (Amomi Fructus Rotundus, 0.5 qian) are added, it becomes Xiang Sha Liu Jun Zi Tang (Aucklandia and Amomum Six-Gentlemen Decoction).
