妊娠之妇，每多恶心呕吐，胀满不食，《巢氏病源》谓之恶阻。此证惟胃气弱而兼滞者
多有之，或嗜酸择食，或肢体困倦，或烦闷胀满，皆其候也。然亦有虚实不同，所当辨而治
之。
凡恶阻多由胃虚气滞，然亦有素本不虚，而忽受胎妊，则冲任上壅，气不下行，故为呕
逆等证；及三月余而呕吐渐止者，何也？盖胎元渐大，则脏气仅供胎气，故无暇上逆矣。凡
治此者，宜以半夏茯苓汤、人参橘皮汤之类，随宜调理，使之渐安，必俟及期，方得帖然也
。若中脘多痰者，用二陈汤加枳壳，或用半夏茯苓汤。若饮食停滞作胀者，宜小和中饮加减
主之。若气逆作胀者，宜半夏茯苓汤加枳壳、苏梗、香附。若脾胃气虚者，宜五味异功散、
六君子汤、人参橘皮汤之类主之。若胃虚兼寒多呕者，宜六味异功煎、温胃饮之类主之。若
肝肾阳虚作呕者，宜理阴煎主之。
立斋曰∶半夏乃健脾气、化痰滞之主药也。脾胃虚弱而呕吐，或痰涎壅滞，饮食少思，
胎不安，必用茯苓半夏汤，倍加白术，以半夏、白术、茯苓、陈皮、砂仁善能安胎气、健脾
胃，予常用，验矣。

怀孕的妇女，常常出现恶心呕吐、腹胀满不想吃东西的症状，《巢氏病源》称之为恶阻。这种病症多见于胃气虚弱兼有气滞的人，或者嗜酸挑食，或者肢体困倦，或者烦闷胀满，这些都是它的证候表现。然而也有虚实不同，应当辨别后进行治疗。
大凡恶阻多由胃虚气滞引起，但也有原本不虚，忽然受孕，导致冲任二脉之气上壅，气不能下行，所以出现呕吐等证；等到三个月以后呕吐逐渐停止，为什么呢？大概是因为胎元逐渐长大，脏腑之气仅供给胎气，所以没有闲暇上逆了。凡是治疗此病的，适宜用半夏茯苓汤、人参橘皮汤之类的方剂，根据情况调理，使病情逐渐安定，必须等到预产期临近，才能安稳。如果中脘部痰多者，用二陈汤加枳壳，或者用半夏茯苓汤。如果饮食停滞导致胀满者，适宜用小和中饮加减主治。如果气逆导致胀满者，适宜用半夏茯苓汤加枳壳、苏梗、香附。如果脾胃气虚者，适宜用五味异功散、六君子汤、人参橘皮汤之类的方剂主治。如果胃虚兼寒且多呕吐者，适宜用六味异功煎、温胃饮之类的方剂主治。如果肝肾阳虚导致呕吐者，适宜用理阴煎主治。
薛立斋说：半夏是健脾气、化痰滞的主要药物。脾胃虚弱而呕吐，或者痰涎壅滞，饮食少思，胎不安，必须用茯苓半夏汤，加倍加入白术，因为半夏、白术、茯苓、陈皮、砂仁善于安胎气、健脾胃，我常用此法，验证有效。

Pregnant women often experience nausea, vomiting, abdominal distension, and loss of appetite. *Chao Shi Bing Yuan* (Source of Diseases by Chao Yuanfang) refers to this condition as Ezu (Morning Sickness). This syndrome is common in those with weak Stomach Qi accompanied by Qi stagnation, or those who crave sour foods and are picky eaters, or who suffer from limb fatigue, irritability, and distension; these are all its manifestations. However, there are differences between deficiency and excess patterns, which must be differentiated for treatment.
Generally, Ezu is caused by Stomach deficiency and Qi stagnation. However, some individuals who were not originally deficient may suddenly conceive, causing the Qi of the Chong and Ren vessels to surge upward without descending, leading to symptoms such as vomiting and reversal of Qi. Why does vomiting gradually cease after three months? It is because as the fetal origin grows larger, the Qi of the Zang-Fu organs is solely dedicated to nourishing the fetus, leaving no surplus to rebel upward. In treating this condition, it is appropriate to use formulas such as Banxia Fuling Tang (Pinellia and Poria Decoction) or Renshen Jupi Tang (Ginseng and Tangerine Peel Decoction), adjusting according to circumstances to bring gradual peace, until the time of delivery approaches, when stability can be achieved. If there is excessive phlegm in the epigastrium, use Erchen Tang (Two-Cured Decoction) with added Zhike (Aurantium Fructus) or Banxia Fuling Tang. If distension is caused by food stagnation, Xiaohesh Yin (Minor Harmonizing Decoction) should be modified and used as the main treatment. If distension is caused by rebellious Qi, Banxia Fuling Tang with added Zhike, Sugen (Perilla Stem), and Xiangfu (Cyperus Rhizome) is suitable. If there is Spleen and Stomach Qi deficiency, Wuwei Yigong San (Five-Ingredient Yigong Powder), Liu Junzi Tang (Six-Gentlemen Decoction), or Renshen Jupi Tang are suitable. If there is Stomach deficiency combined with Cold and frequent vomiting, Liuwei Yigong Jian (Six-Ingredient Yigong Decoction) or Wenwei Yin (Warming the Stomach Infusion) are suitable. If vomiting is caused by Kidney and Liver Yang deficiency, Liyin Jian (Nourishing Yin Decoction) is suitable.
Xue Lizhai stated: Banxia (Pinelliae Rhizoma) is the principal herb for strengthening Spleen Qi and resolving phlegmatic stagnation. In cases of Spleen and Stomach weakness with vomiting, or phlegm-saliva obstruction, poor appetite, and fetal instability, Fuling Banxia Tang (Poria and Pinellia Decoction) must be used, with doubled Baizhu (Atractylodis Macrocephalae Rhizoma). This is because Banxia, Baizhu, Fuling (Poria), Chenpi (Citri Reticulatae Pericarpium), and Sharen (Amomi Fructus) are effective in calming the fetus and strengthening the Spleen and Stomach. I have frequently used this method with verified efficacy.
