妇人怀娠之后，恶心呕吐，思酸解渴，见食憎恶，困倦欲卧，人皆曰妊娠恶阻也，谁知是肝血太燥乎！夫妇人受
妊，本于肾气之旺也，肾旺是以摄精，然肾一受精而完娠，则肾水生胎，不暇化润于五脏；而肝为肾之子，日食母气
以舒，一日无津液之养，则肝气迫索，而肾水不能应，则肝益急，肝急则火动而逆也；肝气既逆，是以呕吐恶心之
症生焉。呕吐纵不至太甚，而其伤气则一也。气既受伤，则肝血愈耗，世人用四物汤治胎前诸症者，正以其能生肝
之血也。然补肝以生血，未为不佳，但生血而不知生气，则脾胃衰微，不胜频呕，犹恐气虚则血不易生也。故于平
肝补血之中，加以健脾开胃之品，以生阳气，则气能生血，尤益胎气耳。或疑气逆而用补气之药，不益助其逆乎！不
知妊娠恶阻，其逆不甚，且逆是因虚而逆，非因邪而逆也。因邪而逆者，助其气则逆增；因虚而逆者，补其气则逆转。
况补气于补血之中，则阴足以制阳，又何虑其增逆乎！
宜用顺肝益气汤。
人参（一两） 当归（一两，酒洗） 苏子（一两，炒，研） 白术（三钱，土炒） 茯苓（二钱） 熟地（五钱，
九蒸） 白芍（三钱，酒炒） 麦冬（三钱，去心） 熟陈皮（三分） 砂仁（一粒，炒，研） 神曲（一钱，炒）
水煎。服一剂轻，二剂平，三剂全愈。此方平肝则肝逆除，补肾则肝燥息，补气则血易生。凡胎病而少带恶阻
者，俱以此方投之无不安，最有益于胎妇，其功更胜于四物焉。
眉批∶方极效，但苏子一两。疑是一钱之误。然国初上元生人，禀赋最壮，或非用一两不效。今当下元，用
一钱可也，万不可用一两。
亦有肝郁气滞，胸膈膨闷，见食不恶，不能多食，虽系妊娠，而非恶阻。宜分别治之，后另有方。

妇女怀孕之后，出现恶心呕吐、想吃酸味食物以解渴、见到食物就厌恶、疲倦想躺卧的症状，人们都说是妊娠恶阻病，谁知道这是因为肝血过于干燥呢！妇女受孕，根本在于肾气的旺盛。肾气旺盛所以能摄精，然而肾脏一旦受精形成胚胎，肾水便用来滋养胎儿，没有余力去滋润五脏；而肝是肾的“子”脏（水生木），每天依赖母脏（肾）的气来舒展，如果一天得不到津液的滋养，肝气就会变得急迫收敛，而肾水又不能及时响应，导致肝气更加急躁，肝气急躁则引发内火并向上冲逆。肝气既然上逆，于是产生了呕吐、恶心等症状。呕吐即使不至于非常严重，但损伤正气是一样的。正气既然受伤，肝血就会更加耗损。世人用四物汤治疗胎前的各种病症，正是因为它能够补生肝血。但是，只懂得通过补血来养肝，虽然不错，但如果只知道生血而不懂得生气，那么脾胃就会衰微，无法承受频繁的呕吐，况且恐怕气虚则血也不容易生成。所以在平抑肝气、补养血液的同时，加入健脾开胃的药物，以生发阳气，这样气能生血，尤其对胎气有益。有人怀疑：气机上逆却使用补气药，不是会助长气逆吗？不知道妊娠恶阻的气逆并不严重，而且这种逆是因为虚弱导致的，不是因为邪气阻滞导致的。因邪气阻滞而气逆的，补气会使气逆加重；因虚弱而气逆的，补气反而能使气机逆转恢复正常。何况在补血之中配合补气，阴液足以制约阳热，又何必担心它会增加气逆呢！
适宜使用顺肝益气汤。
人参（一两）、当归（一两，酒洗）、苏子（一两，炒后研碎）、白术（三钱，土炒）、茯苓（二钱）、熟地黄（五钱，九蒸）、白芍（三钱，酒炒）、麦冬（三钱，去心）、熟陈皮（三分）、砂仁（一粒，炒后研碎）、神曲（一钱，炒）。
用水煎服。服用一剂症状减轻，两剂平稳，三剂痊愈。此方平抑肝气则肝逆消除，补肾则肝燥平息，补气则血液容易生成。凡是胎病且轻微伴有恶阻症状的，都用此方投治无不平安，最有益于孕妇，其功效更胜过四物汤。
眉批：此方效果极好，但苏子用一两，怀疑是一钱的误写。然而清初出生的人，禀赋最强壮，或许不用一两就不见效。如今已是清末，体质较弱，用一钱即可，万万不可用一两。
也有因为肝气郁结、气机阻滞，导致胸膈胀闷，见到食物并不厌恶，只是不能多吃，这虽然是妊娠反应，但不是恶阻病。应当分别治疗，后面另有方剂。

After a woman becomes pregnant, she experiences nausea and vomiting, a craving for sour foods to quench thirst, aversion to food, fatigue, and a desire to lie down. People generally call this condition "pregnancy malaise" (Qiren Ezu). Little do they know that it is actually caused by excessive dryness of Liver Blood! The conception of a woman originates from the prosperity of Kidney Qi. Because Kidney Qi is prosperous, it can grasp essence. However, once the Kidney receives essence and forms an embryo, Kidney Water is used to nourish the fetus and has no spare capacity to moisten the five Zang organs. Since the Liver is the "child" organ of the Kidney (Water generates Wood), it relies daily on the maternal organ's (Kidney) Qi to expand and relax. If it lacks fluid nourishment for even one day, Liver Qi becomes urgent and contracted, while Kidney Water fails to respond in time, causing Liver Qi to become increasingly irritable. When Liver Qi is irritable, internal fire arises and rebels upward. Once Liver Qi rebels, symptoms such as vomiting and nausea arise. Even if vomiting is not severe, the damage to Qi is the same. Once Qi is damaged, Liver Blood is further depleted. The reason why people use Siwu Tang (Four Substance Decoction) to treat various conditions during pregnancy is precisely because it can generate Liver Blood. However, merely nourishing the Liver through blood generation, although not bad, is insufficient if one does not understand how to generate Qi; otherwise, the Spleen and Stomach will weaken and fail to withstand frequent vomiting. Moreover, it is feared that if Qi is deficient, Blood will be difficult to generate. Therefore, within the framework of soothing the Liver and nourishing Blood, herbs that strengthen the Spleen and stimulate appetite are added to generate Yang Qi. In this way, Qi can generate Blood, which is particularly beneficial to fetal Qi. Some may doubt: "If Qi is rebelling, using Qi-tonifying herbs will only exacerbate the rebellion!" They do not realize that in pregnancy malaise, the rebellion is not severe, and the rebellion is due to deficiency rather than pathogenic factors. For rebellions caused by pathogens, tonifying Qi increases rebellion; for rebellions caused by deficiency, tonifying Qi reverses the trend towards normalcy. Furthermore, when Qi is tonified amidst Blood-nourishing herbs, Yin is sufficient to control Yang, so there is no need to worry about increasing rebellion!
The appropriate prescription is Shun Gan Yi Qi Tang (Liver-Soothing and Qi-Boosting Decoction).
Ren Shen (Ginseng Radix et Rhizoma, 1 liang), Dang Gui (Angelicae Sinensis Radix, 1 liang, washed with wine), Su Zi (Perilla Fructus, 1 liang, stir-fried and crushed), Bai Zhu (Atractylodis Macrocephalae Rhizoma, 3 qian, stir-fried with soil), Fu Ling (Poria, 2 qian), Shu Di Huang (Rehmanniae Radix Praeparata, 5 qian, steamed nine times), Bai Shao (Paeoniae Radix Alba, 3 qian, stir-fried with wine), Mai Dong (Ophiopogonis Radix, 3 qian, heart removed), Shu Chen Pi (Citri Reticulatae Pericarpium Praeparatum, 3 fen), Sha Ren (Amomi Fructus Rotundus, 1 grain, stir-fried and crushed), Shen Qu (Massa Medicata Fermentata, 1 qian, stir-fried).
Decoct in water and take orally. After one dose, symptoms lighten; after two doses, stability is achieved; after three doses, complete recovery occurs. This formula soothes the Liver to eliminate rebellion, tonifies the Kidney to extinguish Liver dryness, and tonifies Qi to facilitate Blood generation. For any fetal disorders accompanied by mild pregnancy malaise, administering this formula ensures safety and peace. It is most beneficial to pregnant women, surpassing the efficacy of Siwu Tang (Four Substance Decoction).
Marginal Note: The formula is extremely effective, but the use of 1 liang of Su Zi (Perilla Fructus) seems like a typo for 1 qian. However, individuals born in the early Qing Dynasty had robust constitutions, so perhaps 1 liang was necessary for efficacy. Now, in the late Qing period, constitutions are weaker, so 1 qian is sufficient. One must absolutely avoid using 1 liang.
There are also cases of Liver Qi stagnation and Qi mechanism obstruction, leading to chest and diaphragm distension and fullness, without aversion to food, but with an inability to eat large amounts. Although this occurs during pregnancy, it is not pregnancy malaise. These conditions should be treated differently; see the subsequent formula.
