妊娠恶阻病，在《产宝》中被称为子病，在巢元方的《诸病源候论》中称为恶阻。是指妇女怀孕后出现恶心症状，阻碍了正常饮食。这是由于胃气虚弱，中脘部位停聚痰饮所致。脉象平和顺适，仅表现为肢体沉重、头晕目眩、挑食，特别嗜好酸味和咸味食物；病情严重的会出现寒热交替、呕吐、胸膈部烦闷胀满。一般来说，肥胖的人多痰湿，消瘦的人多内火，治疗应以二陈汤为主方。
保生汤
主治妇人月经停止，身体没有明显疾病但感觉不适。脉象滑大而六脉均匀，这是妊娠的脉象。精神状态如常，厌恶食物的气味，或者只想吃某一种食物，或者大量呕吐清水，这叫做恶阻。千万不要当作寒证来治疗。
药材：人参、甘草（各二钱半）、白术、陈皮、香附、乌药（各五钱）。
如果感到恶心呕吐，加入丁香。
以上药材制成两剂，加生姜三片煎服。
复元汤
主治孕妇呕吐不止，或者头痛完全不想进食，左脉虚弱，服用其他药物无效，此方用于调理血液使其回归本源。
药材：人参、白芍、当归、川芎（各五钱）、白术、茯苓、陈皮（各一两半）、桔梗、枳壳（各二钱半）、丁香（三钱）、甘草（五钱）、半夏（用姜汁浸泡，一两）。
以上药材制成十剂，加生姜、大枣煎服。
妊娠前三个月内，出现呕吐恶心，不吃米食，可用四物汤加上陈皮、半夏、藿香、砂仁、白术、神曲、麦芽、陈仓米、生姜煎服。
妊娠子烦，是指烦躁不安且闷乱心神。大概是因为怀孕四个月时受少阴君火滋养精气，六个月时受少阳相火滋养元气。如果母亲心惊胆战、恐惧寒冷，大多会出现这种症状。《产宝》说：这是心肺虚热，或者痰积在胸部。如果在怀孕三个月时出现烦躁，只是因为有热邪而已。如果是因痰饮导致的烦躁，会吐涎沫、厌恶饮食。大凡痰饮停滞，寒热相互搏结，呕吐严重时会导致胎动不安。使用竹叶汤治疗。
竹叶汤
药材：防风（去芦头）、麦冬（泡过，去心）、白茯苓、黄芩（各等分）。
以上药材为一剂，用竹叶十片，加水煎煮，饭后温服。
The disease of nausea and vomiting during pregnancy (Ezu, 恶阻), referred to as "Zibing" (Sub-disease) in *Chanbao* and "Ezu" in Chao Yuanfang's *Zhubing Yuanhou Lun*, refers to the nausea experienced by women during pregnancy, which obstructs normal dietary intake. This condition arises from weak Stomach Qi and the retention of phlegm-fluids in the Middle Jiao (Middle Burner). The pulse is harmonious and smooth, presenting mainly with heavy limbs, dizziness, picky eating habits, and a strong craving for sour and salty flavors. In severe cases, it manifests as alternating chills and fever, vomiting, and irritability or fullness in the chest and diaphragm. Generally, obese individuals tend to have excessive phlegm, while thin individuals tend to have internal fire; treatment should primarily utilize Erchen Tang (Two-Cured Decoction).
Baosheng Tang (Preserve Life Decoction)
Indicated for women whose menstruation has ceased, who appear healthy but feel unwell. The pulse is slippery and large, with all six positions uniform, indicating a pregnancy pulse. Mental spirit remains unchanged, yet there is aversion to food odors, or a desire to eat only specific foods, or profuse vomiting of clear fluid. This is named Ezu. Do not mistakenly treat this as a Cold syndrome.
Ingredients: Renshen (Ginseng Radix et Rhizoma), Gancao (Licorice Root and Rhizome) (each 2.5 qian); Baizhu (Atractylodis Macrocephalae Rhizoma), Chenpi (Citri Reticulatae Pericarpium), Xiangfu (Cyperi Rhizoma), Wuyao (Linderae Radix) (each 5 qian).
If nausea and vomiting are felt, add Dingxiang (Caryophylli Flos).
Prepare as two doses, decoct with three slices of Shengjiang (Zingiberis Rhizoma Recens) and take orally.
Fuyuan Tang (Restore Primordial Decoction)
Indicated for pregnant women with incessant vomiting, or headache with complete loss of appetite, a weak left pulse, and ineffectiveness of other medications. This formula is used to regulate blood and return it to its origin.
Ingredients: Renshen (Ginseng Radix et Rhizoma), Baishao (Paeoniae Radix Alba), Danggui (Angelicae Sinensis Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma) (each 5 qian); Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), Chenpi (Citri Reticulatae Pericarpium) (each 1.5 liang); Jiegeng (Platycodonis Radix), Zhike (Aurantii Fructus Immaturus) (each 2.5 qian); Dingxiang (Caryophylli Flos) (3 qian); Gancao (Licorice Root and Rhizome) (5 qian); Banxia (Pinelliae Rhizoma) (soaked in Jiangtang [Ginger Juice], 1 liang).
Prepare as ten doses, decoct with Shengjiang (Zingiberis Rhizoma Recens) and Dazao (Jujubae Fructus) and take orally.
For nausea and vomiting occurring within the first three months of pregnancy, where rice food is not tolerated, use Siwu Tang (Four-Substance Decoction) added with Chenpi (Citri Reticulatae Pericarpium), Banxia (Pinelliae Rhizoma), Huoxiang (Agastaches Herba), Sharen (Amomi Fructus), Baizhu (Atractylodis Macrocephalae Rhizoma), Shenqu (Massa Medicata Fermentata), Maiya (Hordei Fructus Germinatus), Chen Cangmi (Rizum Oryzae Sativae Condita), and Shengjiang (Zingiberis Rhizoma Recens), decocted and taken orally.
Zhenzi Fan (Pregnancy-related Subtle Irritability) refers to a state of irritability and mental confusion. It is generally believed that at four months of gestation, the Shaoyin Junfire (Ministerial Fire of Shaoyin) nourishes the essence, and at six months, the Shaoyang Xiangfire (Assistantial Fire of Shaoyang) nourishes the qi. If the mother experiences fright, fear, or coldness, this symptom often occurs. *Chanbao* states: this is due to deficiency-heat in the Heart and Lungs, or phlegm accumulation in the chest. If irritability occurs at three months, it is merely due to heat. If irritability is caused by phlegm-fluids, there will be spitting of saliva and aversion to food. Generally, when phlegm and fluids stagnate, and cold and heat struggle against each other, severe vomiting may lead to unstable fetus. Treat with Zhuye Tang (Bamboo Leaf Decoction).
Zhuye Tang (Bamboo Leaf Decoction)
Ingredients: Fangfeng (Saposhnikoviae Radix) (remove rhizome head), Maidong (Ophiopogonis Radix) (soak, remove heart), Fuling (Poria), Huangqin (Scutellariae Radix) (equal parts).
Prepare one dose, use ten leaves of Zhuye (Phyllostachys Nigra Folium), decoct with water, and take warm after meals.
