恶心、头眩、恶食、择食是也。
怀娠两月，宜绝医药。妊娠一月，足厥阴脉养之；二月足少阳脉养之，多致恶心、头眩、喜酸，俗为之病儿，非医
药所治，治之则愈甚，待其自安可耳。
怀娠一月，不须安胎。胎未成而呕吐，母病也。若注意安胎，便用砂、芩之类，则反伤脾胃，故但当治其母病，则
呕逆自止，惟方药有与病相合，而于胎不相宜者，当去之。
中气不运。孕当两三月，因中气多滞，不能运化，不思谷味，闻食即恶心，多阻，宜疏理脾胃，香砂六君子汤。（和
三。）加乌梅亦可。
禀受怯弱。气血不足，转致内郁，郁气上冲于胃则呕逆，血虚而心失所养则烦闷。宜调血散郁为主，参橘饮。（和一。）
甚有虚弱之极，或作寒热往来，倦怠不能自支，此肝肾不足也，须兼补足厥阴与足少阴经。
胃有痰饮。血壅不行，则饮随气上，停滞肝经，故喜酸物，惟金能克木，宜以辛味胜之，砂仁、藿香，自不可少。
半夏虽损胎，不妨权用，但不宜多耳。半夏茯苓汤可酌用之。（和二。）
胃气虚寒。宜温补脾胃，以下其逆气，六君子汤。（补一。）
肝火冲胃。寅卯时觉少腹有气上冲，此肝火挟冲脉之火上冲也，故心中烦愦热闷，呕逆不止。宜竹茹麦冬汤。（寒一。）
气郁伤肝。大怒后，肝气挟胎气上逆也，故胸满眩晕而吐逆，宜疏肝，不宜补气。抑青丸可治。（散一。）
外伤风寒。呕而头晕，亦有兼风寒外袭者。宜于调气之中，加紫苏以散之。虚则可投参苏二味。
上实下虚。恶阻若兼腰痛，谨防胎堕。宜六君合四物去川芎，加川断、杜仲以安之。切勿用升举药，愈升则上愈实
而下愈虚，是促其堕矣。（补一、补七。）
呕吐不受药。津液燥涸，少阴虚火上浮，厥阴郁火上达，少阳伏火上乘，是以呕吐不能受药也。速当救急以治其标，
滋阴清燥汤。（寒一。）
怀孕两个月时，应当停止使用药物。怀孕第一个月，由足厥阴肝经滋养胎元；第二个月，由足少阳胆经滋养胎元，此时多出现恶心、头晕、喜食酸味等症状，民间称之为“病儿”，这并非疾病，不需要药物治疗。如果强行治疗，症状反而会加重，只需等待其自行安定即可。
怀孕一个月时，不需要特意安胎。此时胎元尚未形成，若出现呕吐，是母体自身的病症。如果刻意注重安胎，便使用砂仁、黄芩等药物，反而损伤脾胃功能。因此，只应当治疗母体的疾病，呕吐自然就会停止。只有当方药与病情相符但与胎儿不相宜时，才需要去除那些对胎儿不利的药物。
中气运行不畅。怀孕两三个月时，由于中焦之气多有阻滞，不能正常运化水谷，导致不思饮食，闻到食物气味就恶心，阻滞感明显，适宜疏理脾胃，可用香砂六君子汤。（参考和剂篇第三条）加入乌梅也可以。
禀赋怯弱。气血不足，进而导致气机内郁，郁滞之气上冲于胃则引发呕吐，血虚而心失所养则感到烦闷。适宜以调和血液、疏散郁结为主，可用参橘饮。（参考和剂篇第一条）如果虚弱到了极点，或者出现寒热往来的症状，倦怠乏力无法支撑，这是肝肾不足的表现，必须同时补益足厥阴肝经与足少阴肾经。
胃中有痰饮。血液壅滞不行，则痰饮随气机上逆，停滞于肝经，所以喜欢酸味食物。因为金能克木（辛味属金，酸味属木），适宜用辛味来制约它，砂仁、藿香是不可缺少的药物。半夏虽然可能损伤胎元，但也不妨权且使用，只是不宜多用。半夏茯苓汤可以酌情使用。（参考和剂篇第二条）
胃气虚寒。适宜温补脾胃，以降逆气，可用六君子汤。（参考补益篇第一条）
肝火冲犯胃腑。在寅时到卯时（凌晨3点至7点）感觉小腹有气上冲，这是肝火挟带冲脉之火上冲所致，所以心中烦乱闷热，呕吐不止。适宜用竹茹麦冬汤。（参考清热篇第一条）
气郁伤肝。在大怒之后，肝气挟带胎气上逆，所以胸膈满闷、眩晕并伴有呕吐，适宜疏肝解郁，不宜补气。抑青丸可以治疗。（参考散邪篇第一条）
外伤风寒。呕吐并伴有头晕，也有兼夹风寒外袭的情况。适宜在调理气机的基础上，加入紫苏以发散风寒。体质虚弱者可以投用参苏二味药（人参、苏叶）。
上实下虚。恶阻如果兼有腰痛，要谨防流产。适宜用六君子汤合四物汤，去掉川芎，加入川断、杜仲以安胎。切勿使用升提举陷的药物，越升提则上部越实，下部越虚，这会促使流产发生。（参考补益篇一、七条）
呕吐剧烈，无法服药。津液干燥枯竭，少阴肾经虚火上浮，厥阴肝经郁火上达，少阳胆经伏火上乘，导致呕吐剧烈而不能受纳药物。应当迅速急救以治其标，可用滋阴清燥汤。（参考清热篇第一条）
Nausea, dizziness, food aversion, and selective eating constitute this condition.
During the second month of pregnancy, medicinal treatment should be discontinued. In the first month of gestation, the Foot-Jueyin Liver Meridian nourishes the fetus; in the second month, the Foot-Shaoyang Gallbladder Meridian nourishes it. This often leads to nausea, dizziness, and a preference for sour foods. Commonly referred to as "sickness of the child," it is not a disease requiring medical intervention. Treatment may exacerbate symptoms; it is best to wait for spontaneous resolution.
In the first month of pregnancy, fetal stabilization measures are unnecessary. As the fetus has not yet fully formed, vomiting at this stage is a maternal disorder. If one focuses excessively on stabilizing the fetus by using herbs such as Amomum fruit (Sharen) and Scutellaria root (Huangqin), it may反而 damage the Spleen and Stomach. Therefore, one should treat the maternal illness directly, after which vomiting will cease naturally. Only when a prescription matches the disease but is unsuitable for the fetus should those specific components be removed.
Impaired movement of Middle Qi. During the second or third month of pregnancy, stagnation of Middle Qi often prevents proper transformation and transportation, leading to loss of appetite and nausea upon smelling food. This obstruction is suitable for regulating the Spleen and Stomach with Xiangsha Liujunzi Tang (Aromatic Sand-Cardamom Six Gentlemen Decoction). Adding Mume fruit (Wumei) is also effective.
Constitutional weakness. Insufficiency of Qi and Blood leads to internal stagnation. Stagnant Qi rushing upward to the Stomach causes vomiting; Blood deficiency failing to nourish the Heart results in restlessness and oppression. The primary approach should be to harmonize Blood and dissipate stagnation using Shenju Yin (Ginseng and Tangerine Peel Drink). In cases of extreme weakness, or where alternating chills and fever occur alongside profound fatigue, this indicates insufficiency of the Liver and Kidney. It is necessary to tonify both the Foot-Jueyin Liver Meridian and the Foot-Shaoyin Kidney Meridian.
Phlegm-fluid retention in the Stomach. When Blood becomes stagnant, fluids follow Qi upward and stagnate in the Liver Meridian, causing a craving for sour substances. Since Metal controls Wood (Sour corresponds to Wood, Pungent to Metal), it is appropriate to use Pungent flavors to overcome this, making Amomum fruit (Sharen) and Agastache herb (Huoxiang) indispensable. Although Pinellia tuber (Banxia) may potentially harm the fetus, it can be used temporarily without hesitation, provided it is not overused. Banxia Fuling Tang (Pinellia and Polyporus Decoction) may be considered.
Deficiency-Cold of Stomach Qi. It is appropriate to warm and tonify the Spleen and Stomach to direct rebellious Qi downward, using Liujunzi Tang (Six Gentlemen Decoction).
Liver Fire attacking the Stomach. A sensation of Qi rushing upward from the lower abdomen during the Yin and Mao hours (03:00–07:00) indicates Liver Fire carrying Chong Mai (Penetrating Vessel) fire upward. This causes mental restlessness, heat, and oppression, along with persistent vomiting. Zhuru Maidong Tang (Bamboo Shave and Ophiopogon Decoction) is indicated.
Qi Stagnation injuring the Liver. Following severe anger, Liver Qi carries fetal Qi upward in rebellion, causing chest fullness, dizziness, and vomiting. The treatment should focus on soothing the Liver rather than tonifying Qi. Yiqing Wan (Suppress Blue Pill) is applicable.
External invasion of Wind-Cold. Vomiting accompanied by dizziness may also result from concurrent external Wind-Cold invasion. Within the framework of regulating Qi, Perilla leaf (Zisu) should be added to disperse the pathogen. For deficient constitutions, a combination of Ginseng (Renshen) and Perilla leaf (Zisu) may be used.
Excess above and Deficiency below. If nausea and vomiting are accompanied by lower back pain, there is a risk of miscarriage. It is appropriate to combine Liujunzi Tang with Siwu Tang, removing Ligusticum rhizome (Chuanxiong), and adding Dipsacus root (Chuanduan) and Eucommia bark (Duzhong) to stabilize the fetus. Elevating agents must strictly be avoided; further elevation increases upper excess and lower deficiency, thereby precipitating miscarriage.
Severe vomiting preventing medication intake. Dryness and depletion of Body Fluids, with Deficient Fire floating upward from the Shaoyin Kidney, Depressed Fire reaching up from the Jueyin Liver, and Hidden Fire surging from the Shaoyang Gallbladder, result in severe vomiting that cannot tolerate oral medication. Urgent symptomatic treatment is required using Ziyin Qingzao Tang (Nourish Yin and Clear Dryness Decoction).
