妊娠阻病，按照昝殷《产宝方》的说法称为子病。《巢氏病源》称之为恶阻。如果妇人先天禀赋怯弱，或者体内有风气，或者有痰饮，一旦怀孕就会患上这种病。其症状表现为面色如常，脉象和顺。但感觉肢体沉重，头目昏眩，挑食，厌恶食物的气味，喜欢酸咸口味；严重的甚至出现寒热往来，心中烦闷，呕吐痰水，胸膈脘腹烦满，精神恍惚难以支撑。不论是在怀孕初期还是其他时候，只要疾病痛苦有轻重之分罢了。轻的，不服药也无妨；重的必须用药治疗。《千金方》中有半夏茯苓汤、茯苓丸两个方子，专门治疗阻病。然而这两个方剂，近来很少有人服用，因为半夏有动胎气的性质。大概是因为胎儿刚结成，担心容易流产散失，这是不可不谨慎的。张仲景《伤寒论》说：妇人伤风，接连出现寒热，发作有定时，这是热入血室（邪热侵入子宫血分）。有用黄龙汤的，也有用小柴胡汤去掉半夏的。这大概是专门为孕妇设立的治法。王子亨则有白术散，《太平惠民和剂局方》则有人参丁香散，使用效果很好。然而这三个方子大体相同而细节略有差异。杨振则有人参橘皮汤，齐士明则有醒脾饮，我试用过也有效。这些方子都不用半夏等动胎气的药物。服药的人要知晓这一点。
治疗恶阻呕吐清水，严重时十余天连粥浆都进不去的方子。

Pregnancy-related obstruction disease, according to Zan Yin's *Chanbao Fang* (Precious Formulas for Childbirth), is referred to as "Zi Bing" (Fetal Disease). *Chao Shi Bing Yuan* (Source of Diseases by Chao Yuanfang) calls it "E Zu" (Nausea and Obstruction of Pregnancy). If a woman has a weak constitution, or has wind-pathogens in her body, or has phlegm-fluid retention, she will suffer from this disease upon becoming pregnant. Her complexion remains unchanged, and her pulse is harmonious and smooth. However, she feels heaviness in her limbs, dizziness in the head and eyes, picky eating habits, aversion to food odors, and a craving for sour and salty tastes; severe cases may present with alternating chills and fever, mental restlessness, vomiting of phlegm-water, fullness and discomfort in the chest and abdomen, and a trance-like state where she cannot support herself. This applies regardless of whether it occurs early in pregnancy or later; the key difference lies only in the severity of the suffering. For mild cases, abstaining from medication is acceptable; for severe cases, medicinal treatment is necessary. *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) contains two formulas specifically for treating obstruction disease: Banxia Fuling Tang (Pinellia and Poria Decoction) and Fuling Wan (Poria Pill). However, these two formulas are rarely used nowadays because Banxia (Pinelliae Rhizoma) has properties that can disturb the fetus. Since the fetus is just forming, there is concern about its potential to scatter or abort; thus, caution is imperative. Zhang Zhongjing's *Shanghan Lun* (Treatise on Cold Damage Disorders) states: "When a woman contracts wind-cold and subsequently develops alternating chills and fever at regular intervals, this indicates Heat entering the Blood Chamber (Xue Shi)." Some practitioners use Huanglong Tang (Yellow Dragon Decoction), while others use Xiao Chaihu Tang (Minor Bupleurum Decoction) with Banxia removed. These approaches seem designed specifically for pregnant women. Wang Ziheng proposed Baizhu San (Atractylodes Macrocephala Powder), and *Ju Fang* (Formulas of the Bureau) offers Renshen Dingxiang San (Ginseng and Clove Powder), both of which have proven effective. Although these three formulas are largely similar with minor differences, Yang Zhen proposed Renshen Jupi Tang (Ginseng and Tangerine Peel Decoction), and Qi Shiming proposed Xingpi Yin (Spleen-Awakening Decoction); I have tested them and found them effective. None of these formulas use Banxia or other herbs that might disturb the fetus. Practitioners should be aware of this.
For treating E Zu (Nausea and Obstruction) with vomiting of clear fluid, where in severe cases no porridge or liquid can be retained for over ten days:
Baizhu (Atractylodis Macrocephalae Rhizoma) (1 liang)
Renshen (Ginseng Radix et Rhizoma) (0.5 liang)
Dingxiang (Caryophylli Flos) (2.5 qian)
Gancao (Glycyrrhizae Radix et Rhizoma) (1 qian)
Grind the above ingredients into a fine powder. Take 2 qian per dose. Add one zhan (approx. 200ml) of water and five slices of Shengjiang (Zingiberis Rhizoma Recens), decoct until reduced to 0.7 zhan, and take warm.
For treating obstruction disease with vomiting of phlegm-water:
Renshen (Ginseng Radix et Rhizoma) (remove Lu/roots)
Chen Juhong (Citri Reticulatae Pericarpium Rubrum)
Baizhu (Atractylodis Macrocephalae Rhizoma)
Mendong (Ophiopogonis Radix) (remove heart, each 1 liang)
Gancao (Glycyrrhizae Radix et Rhizoma) (3 qian)
Houpo (Magnoliae Officinalis Cortex) (processed)
Fuling (Poria) (remove skin, each 0.5 liang)
Grind the above ingredients into a coarse powder. Take 4 qian per dose. Add one and a half zhan of water, a piece of Danshuzhu Ru (Bambusae Caulis in Taenia) the size of a bullet, and three slices of Shengjiang (Zingiberis Rhizoma Recens). Decoct until reduced to 0.7 zhan, strain, clarify, and take warm. Take on an empty stomach or before meals. *Ji Yan Fang* (Collected Proven Prescriptions) omits Fuling, Mendong, and Gancao.
