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。）
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).
