妊娠烦闷有四证，有心中烦，胸中烦，有子烦，诸属于热。若脏虚而气乘心，令人烦者，名虚烦。若
积痰饮，呕吐痰沫者，名胸中烦。或血积停饮，寒热相搏，致胎气不安，谓子烦。大抵多
由阴既养胎，孤阳独旺，心肺虚热，是以撩乱不宁。更有时当盛夏，君火大行，俱能乘肺，以致
烦躁、胎动不安者，皆因时而致之者也，亦当因时治之，生脉散最佳。
妊娠烦躁口干者，足太阴脾经其气通于口，手少阴心经其气

烦大同小异，宜知母丸。若肝经火动，加味逍遥散；若肾经火动，加味地黄丸。
古有妇人暴渴，惟饮五味汁，名医耿隅诊其脉曰∶此血欲凝，非疾也。已而果孕，故古方有血欲凝而渴饮五味之证，
本属肺肾二经有火，盖火入于肺则烦，入于肾则躁，胎系于肾，肾水养其胎元，则不足以滋肾中之火，火上烁肺，变为

《本事方》云∶紫苏饮治妊娠胎气不和，坏胎逆上，胀满疼痛，名子悬。子悬者，浊气举胎上凑也。

心腹胀满者，由腹内素有寒气，致令停饮；与气相争，故令心腹胀满也，须以脉之迟数辨之。
There are four types of restlessness during pregnancy: restlessness in the heart, restlessness in the chest, and *Zi Fan* (pregnancy-related restlessness); these generally belong to heat syndromes. If the internal organs are deficient and Qi ascends to invade the Heart, causing restlessness, it is named *Xu Fan* (deficiency restlessness). If there is accumulation of phlegm-fluids accompanied by vomiting of phlegm foam, it is named *Xiong Zhong Fan* (chest restlessness). If blood stasis and retained fluids contend with cold and heat, leading to instability of fetal Qi, it is called *Zi Fan*. Generally, this arises because Yin blood is consumed to nourish the fetus, leaving Yang unopposed and flourishing alone, resulting in deficiency-heat in the Heart and Lungs, which causes agitation and unrest. Furthermore, if this occurs in midsummer when Ministerial Fire (Heart Fire) is prevalent, it can invade the Lungs, leading to restlessness and unstable fetal movement; these are caused by seasonal factors and should be treated according to the season, with Sheng Mai San (Pulse-Generating Powder) being the most effective.
Regarding restlessness and dry mouth during pregnancy, the Qi of the Foot-Taiyin Spleen Meridian connects to the mouth, and the Qi of the Hand-Shaoyin Heart Meridian connects to the tongue. If the Qi of the internal organs is deficient and heat invades the Heart and Spleen, depleting body fluids and causing fetal dryness, it results in heart restlessness and oral dryness. This is largely similar to *Zi Fan*, and Zhi Mu Wan (Anemarrhena Pill) is appropriate. If Liver Meridian fire is active, Jia Wei Xiao Yao San (Modified Free and Easy Wanderer Powder) should be used; if Kidney Meridian fire is active, Jia Wei Di Huang Wan (Modified Rehmannia Pill) is indicated. Ancient texts record a case where a woman suffered sudden extreme thirst and only drank Wu Wei Zhi (Five-Flavor Juice). The renowned physician Geng Yu diagnosed her pulse and said, "This indicates blood is about to congeal; it is not a disease." She subsequently became pregnant. Thus, ancient formulas mention the syndrome of "thirst due to blood congealing, relieved by drinking five-flavor juice," which originally belongs to fire in the Lung and Kidney meridians. Fire entering the Lung causes *Fan* (restlessness/agitation), while fire entering the Kidney causes *Zao* (irritability). The fetus is rooted in the Kidney; as Kidney Water nourishes the fetal origin, it may be insufficient to control the fire within the Kidney. This fire scorches Lung Metal, transforming into restlessness and irritability, which is a sign of deficiency of Metal and depletion of Water. The treatment method should be to nourish the source of transformation, clear Metal and protect the Lung, and use heavy, rich substances to strengthen Water, focusing primarily on nourishing the Kidney.
The *Ben Shi Fang* states: Zi Su Yin (Perilla Decoction) treats disharmony of fetal Qi during pregnancy, where fetal Qi rebels and ascends, causing distension, fullness, and pain, known as *Zi Xuan* (fetal suspension). *Zi Xuan* refers to turbid Qi rising and pressing against the fetus upwards. Fetal heat and rebellious Qi cause distension and fullness in the Heart and Stomach; this condition mostly involves Qi stagnation. To diffuse Qi and relieve depression, one cannot circulate Qi without Zi Su (Perilla Leaf), Fu Pi (Areca Peel), Chuan Xiong (Sichuan Lovage Rhizome), and Chen Pi (Aged Tangerine Peel); one cannot nourish Blood without Gui (Angelica Sinensis) and Shao (White Peony Root). Once Qi and Blood flow freely, the fetal Qi descends and stabilizes. However, where pathogenic factors gather, healthy Qi must be deficient; therefore, Ren Shen (Ginseng) and Gan Cao (Licorice) are used to tonify. It also states: In cases of heart and abdominal distension and fullness during pregnancy, this is due to pre-existing cold in the abdomen causing retention of fluids; these fluids contend with Qi, causing distension and fullness. This must be differentiated by examining whether the pulse is slow or rapid.
