恶阻病者，心中愦闷，头眩，四肢烦疼，懈惰不欲执作，恶闻食气，欲啖咸酸果实，多
睡少起，世云恶食，又云恶字是也。乃至三四月日以上，大剧者，不能自胜举也。此由妇人
元本虚羸，血气不足，肾气又弱，兼当风饮冷太过，心下有痰水挟之，而有娠也。经血既闭
，水渍于脏，脏气不宣通，故心烦愦闷，气逆而呕吐也；血脉不通，经络痞涩，则四肢沉重
；挟风则头目眩。故欲有胎，而病恶阻。所谓欲有胎者，其人月水尚来，而颜色皮肤如常，
但苦沉重愦闷，不欲食饮，又不知其患所在，脉理顺时平和，即是欲有胎也。如此经二月日
后，便觉不通，则结胎也。
阴阳和调，二气相感，阳施阴化，是以有娠。而三阴所会，则多生女。但妊娠二月，名
曰始藏，精气成于胞里。至于三月，名曰始胎，血脉不流，象形而变，未有定仪，见物而化
，是时男女未分，故未满三月者，可服药方术转之，令生男也。
妊娠之人，有宿挟 疹，因而有娠，或有娠之时，节适乖理，致生疾病，并令腑
脏衰损，气力虚羸，令胎不长。故须服药去其疾病，益其气血，以扶养胎也。
妊娠男女未分之时，未有定仪，见物而化，故须端正庄严，清静和一，无倾视，无邪听
。儿在胎，日月未满，阴阳未备，腑脏骨节，皆未成足，故自初讫于将产，饮食居处，皆有
恶阻病，表现为心中烦乱闷塞，头晕目眩，四肢酸痛沉重，身体懈怠懒惰不想劳作，厌恶食物的气味，想吃咸酸口味的果实，嗜睡而少起，世人称为“恶食”，又有人写作“恶字”（指妊娠反应）。严重者在怀孕三四个月以上时，病情剧烈者，甚至无法支撑起身。这是由于妇人原本体质虚弱羸瘦，气血不足，肾气也虚弱，加上感受风邪、过食生冷太过，导致心下有痰饮停聚夹杂其中，此时又有身孕。月经既已停止，水湿之邪浸渍于脏腑，脏气不能宣通，所以心烦意乱闷塞，气机上逆而呕吐；血脉不通，经络阻滞涩滞，则四肢沉重；夹带风邪则头目眩晕。因此想要受孕，却出现恶阻的病证。所谓“想要受孕”，是指其人月经尚且正常来潮，面色皮肤如常，只是苦于身体沉重闷塞，不想饮食，又不知道病痛所在，脉象顺时应季而平和，这就是将要受孕的表现。像这样经过两个月后，便觉得经血不通，那就是结胎了。
阴阳调和，二气相互感应，阳施阴化，因而有了身孕。而在三阴经所会合之时（指受孕时机或体质倾向），多生女孩。但怀孕到第二个月，名叫“始藏”，精气在胞宫之内形成。到了第三个月，名叫“始胎”，血脉不再流动（指胚胎固定），依循形象而变化，还没有固定的形态，见到外物而发生变化，这时男女尚未区分，所以对于未满三个月的，可以通过服药方术来转化，使其生男孩。
妊娠期间的人，如果有宿疾夹杂疹病，因而怀孕，或者在怀孕之时，生活起居调理违背常理，导致产生疾病，都会使脏腑衰损，气力虚弱羸瘦，导致胎儿发育不良。因此需要服药去除其疾病，补益其气血，以抚养胎儿。
在妊娠男女尚未区分之时，没有固定形态，见物而化，因此必须端正庄严，清静和谐，不要歪斜视物，不要听信邪僻之言。胎儿在母体内，日月未满，阴阳未完备，脏腑骨节，都未长成，所以从最初直到临产，饮食起居，都有（禁忌/讲究）……
Ezu disease manifests as mental restlessness and oppression, dizziness, soreness and pain in the four limbs, lethargy and reluctance to work, aversion to the smell of food, craving for salty and sour fruits, excessive sleepiness with little rising, which is colloquially called "aversion to food" (Eshi), or alternatively written as "Evil Character" (Ezi) referring to pregnancy reactions. In severe cases lasting beyond three or four months, patients may be unable to support themselves. This condition arises because the woman originally had a weak and emaciated constitution, insufficient Qi and Blood, and weak Kidney Qi, compounded by excessive exposure to Wind and consumption of cold foods/drinks, leading to Phlegm-Fluid retention in the epigastrium while simultaneously becoming pregnant. Once the menstrual blood ceases, Water-Dampness infiltrates the Zang organs, causing their Qi to fail in circulating and unblocking freely; thus, there is mental irritability and oppression, rebellious Qi leading to vomiting; when Blood vessels are blocked and meridians become obstructed and stagnant, the four limbs feel heavy; if accompanied by Wind, the head and eyes become dizzy. Therefore, one desires conception but suffers from Ezu. The phrase "desiring conception" refers to a state where menstruation still occurs normally, complexion and skin appear normal, yet the person suffers from heaviness and oppression, lack of appetite, and is unaware of the source of discomfort; when the pulse is smooth and harmonious according to the season, this indicates impending conception. After two months have passed in such a manner, one perceives the cessation of menstruation, indicating that the fetus has formed.
When Yin and Yang are harmonized and the two Qi interact, Yang acts and Yin transforms, resulting in pregnancy. If conception occurs during the time associated with the convergence of the Three Yin channels, female offspring are more likely. However, at two months of pregnancy, it is named "Shi Cang" (Beginning Storage), where Jing-Essence forms within the Bao Palace (Uterus). By the third month, it is named "Shi Tai" (Beginning Fetus); the Blood vessels cease flowing (the embryo stabilizes), changing according to form, without a fixed shape yet, transforming upon seeing external objects. At this stage, male and female distinctions are not yet clear. Therefore, for those less than three months pregnant, medicinal prescriptions and methods can be used to influence the outcome, aiming for a male child.
Pregnant women who have pre-existing conditions or rashes may develop complications upon conception. Alternatively, improper lifestyle management during pregnancy can lead to illness, damaging the Zang-Fu organs and weakening Qi and vitality, thereby hindering fetal growth. Thus, it is necessary to administer medicine to eliminate diseases and tonify Qi and Blood to nourish and support the fetus.
During the period when the fetus's sex is undifferentiated and its form is not yet fixed, transforming upon external stimuli, the mother must maintain dignity, solemnity, purity, and harmony, avoiding distorted gazes and listening to improper sounds. While in the womb, before the full term of months, Yin and Yang are not fully developed, and the Zang-Fu organs and bone joints are not completely formed. Therefore, from the beginning until delivery, diet and living habits must adhere to specific principles...
