腹四苓攒，桑砂苏陈胀加枳，腿脚防己喘葶添。
【注】妊娠水肿胀满、子气、皱脚、脆脚等证，皆由水气湿邪，伤于脾肺为病也。若
水气盛而浸胎，则必喘而难卧；若湿气盛而伤胎，则胀满难堪。皆宜用茯苓导水汤治之，
方用木香、木瓜、槟榔、大腹皮、白术、茯苓、猪苓、泽泻、桑皮、砂仁、苏叶、陈皮，
以和脾肺而利水湿。胀甚者，加枳壳以破结；腿脚肿者，加防己以利下；湿喘者，加苦葶

知母饮
孕妇时烦名子烦，胎热乘心知母痊，子芩知麦苓 草，犀热参虚膏渴煎。
【注】孕妇别无他证，惟时时心烦者，名曰子烦，由胎中郁热上乘于心也。宜用知母

头面及四肢浮肿称为子肿，自膝盖至足部肿胀称为子气，全身肿胀且伴有气喘、腹部胀满称为子满，仅双脚肿胀而皮肤增厚称为皱脚，皮肤变薄称为脆脚。
【注】头面和全身浮肿，小便短少的，属于水气致病，所以叫作子肿。从膝盖到足部肿胀，小便正常的，属于湿气致病，所以叫作子气。全身都肿，腹部胀满且气喘，发生在怀孕六到七个月时的，叫作子满。仅两脚肿胀且皮肤厚实的，属于湿邪，叫作皱脚。皮肤薄的，属于水邪，叫作脆脚。大凡水邪致病多伴有气喘急促，气邪致病多伴有腹部胀满。气喘急促归属于肺，腹部胀满归属于脾。因为孕妇素来体内有水气和湿邪，所以受孕后出现肿胀和胀满的病症。胎儿尚未成形时，被水气浸渍，往往会导致胎损。如果胎儿已经成形尚可调治，所以在怀孕五六月后出现这些症状的，大多能够顺利生育。
茯苓导水汤
治疗妊娠期的水肿胀满与子气，病机在于水气与湿邪滞留于脾肺之间。若水气浸淫胎儿导致气喘难以平卧，若湿气损伤胎儿导致腹胀难以忍受，均适宜使用茯苓导水汤治疗。方中汇集香薷、瓜蒌根、槟榔、大腹皮以及四苓散（茯苓、猪苓、泽泻、白术）。若以腹胀为主，加入枳壳；若腿脚肿胀，加入防己；若气喘严重，加入葶苈子。
【注】妊娠期的水肿胀满、子气、皱脚、脆脚等病症，都是由水气和湿邪伤害脾肺所致。如果水气旺盛并浸淫胎儿，必然会出现气喘且难以平卧的症状；如果湿气旺盛并损伤胎儿，则会出现难以忍受的腹部胀满。这些都适宜用茯苓导水汤治疗。该方由木香、木瓜、槟榔、大腹皮、白术、茯苓、猪苓、泽泻、桑白皮、砂仁、苏叶、陈皮组成，用以调和脾肺并利水除湿。腹胀严重的，加枳壳以破气结；腿脚肿胀的，加防己以利水下行；因湿致喘的，加苦葶苈以宣泄上焦之水。
知母饮
孕妇时常感到心烦称为子烦，此症由胎热乘袭心经，可用知母饮治愈。方中包含黄芩、知母、麦冬、茯苓、甘草。若热势盛者加犀角，气虚者加人参，口渴者加石膏煎服。
【注】孕妇没有其他病症，只是时时感到心烦的，叫作子烦，这是由于胎中郁热上乘于心所致。适宜使用知母饮，即由黄芩、知母、麦冬、茯苓、甘草组成。热势重的加犀角，气虚的加人参，口渴的加石膏煎服。
Head and facial edema along with swelling of the four limbs is termed Zi Zhong (Fetal Edema). Swelling from the knees to the feet is named Zi Qi (Fetal Qi). Generalized swelling accompanied by panting and abdominal fullness is called Zi Man (Fetal Fullness). Swelling confined to the feet with thickened skin is referred to as Zhou Jiao (Wrinkled Feet), while swelling with thin skin is called Cui Jiao (Brittle Feet).
[Note] When the head, face, and entire body are edematous with scanty urine, it is attributed to Water Qi pathogenesis, hence named Zi Zhong. Swelling from the knees to the feet with normal urination is attributed to Dampness pathogenesis, hence named Zi Qi. Generalized swelling, abdominal distension, and panting occurring during the sixth or seventh month of pregnancy are termed Zi Man. Swelling limited to both feet with thickened skin is due to Dampness, named Zhou Jiao. Swelling with thin skin is due to Water, named Cui Jiao. Generally, diseases caused by Water often present with panting and shortness of breath, whereas diseases caused by Qi often present with abdominal distension and fullness. Panting is associated with the Lung, and abdominal distension is associated with the Spleen. This occurs because the woman previously harbored Water Qi and Dampness pathogens; upon conception, these manifest as swelling and fullness. If the fetus has not yet formed, immersion in water may damage the fetus. However, if the fetus has already formed, treatment can still be effective; thus, those presenting with these symptoms after the fifth or sixth month often have successful deliveries.
Fuling Daoshui Decoction (Poria Decoction for Guiding Out Water)
For pregnancy-related edema, fullness, and Zi Qi, the pathology involves Water Qi and Dampness pathogens residing between the Spleen and Lung. If Water Qi overwhelms and immerses the fetus, it causes panting and difficulty lying down; if Dampness overwhelms and damages the fetus, it causes unbearable abdominal distension. Both conditions are suitable for treatment with Fuling Daoshui Decoction. The formula comprises Xiangru (Elsholtziae Herba), Gualougen (Trichosanthis Radix), Binglang (Arecae Semen), Dafupi (Tangerine Fruit Pericarp - specifically Citri Reticulatae Pericarpium Viride or similar contextually used bark), and the Four Poria Powder (Siling San: Fuling, Zhuling, Zexie, Baizhu). For prominent abdominal distension, add Zhike (Aurantii Fructus); for leg and foot swelling, add Fangji (Stephaniae Tetrandrae Radix); for severe panting, add Tinglizi (Lepidii Semen).
[Note] Conditions such as pregnancy edema, fullness, Zi Qi, Zhou Jiao, and Cui Jiao are all caused by Water Qi and Dampness pathogens injuring the Spleen and Lung. If Water Qi is excessive and immerses the fetus, it inevitably leads to panting and inability to lie flat; if Dampness is excessive and damages the fetus, it results in unbearable abdominal distension. All these should be treated with Fuling Daoshui Decoction. The prescription consists of Muxiang (Aucklandiae Radix), Mugua (Chaenomelis Fructus), Binglang (Arecae Semen), Dafupi (Mature Tangerine Peel), Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), Zhuling (Polyporus), Zexie (Alismatis Rhizoma), Sangbai (Mori Cortex), Sharen (Amomi Fructus), Ziye (Perillae Folium), and Chenpi (Citri Reticulatae Pericarpium). It harmonizes the Spleen and Lung while promoting diuresis to resolve dampness. For severe distension, add Zhike to break stagnation; for leg and foot swelling, add Fangji to promote downward drainage of water; for panting caused by dampness, add Ku Tingli to drain upper-jiao water.
Zhimu Yin (Anemarrhenae Decoction)
When a pregnant woman experiences frequent irritability, it is termed Zi Fan (Fetal Irritability). This condition is caused by fetal heat assaulting the Heart and can be cured with Zhimu Yin. The base formula contains Huangqin (Scutellariae Radix), Zhimu (Anemarrhenae Rhizoma), Maidong (Ophiopogonis Tuber), Fuling (Poria), and Gancao (Glycyrrhizae Radix et Rhizoma). If heat is severe, add Xijiao (Rhinocerotis Cornu); if Qi is deficient, add Renshen (Ginseng Radix); if thirst is present, add Shigao (Gypsum Fibrosum) for decoction and administration.
[Note] If a pregnant woman has no other symptoms but experiences frequent mental restlessness, it is called Zi Fan. This arises from stagnant heat within the fetus ascending to the Heart. It is appropriate to use Zhimu Yin, composed of Huangqin, Zhimu, Maidong, Fuling, and Gancao. Add Xijiao for severe heat, Renshen for Qi deficiency, and Shigao for thirst when decocting and taking orally.
