凡产后口燥咽干而渴兼小便不利，由血枯而多汗，且劳倦伤脾，不能为胃行其津液，则生化之气不运，渗泄之
令不行。是以上无津液流通，而有咽干燥渴之症。下则膀胱闭滞，而有水道不通之候。治当助脾益肺，升降气血，
则气血流行，阳升阴降，自然津生而便利矣。若认口渴为火盛，而用芩、连、知、柏以降之。便涩为水滞，而用五
苓等味以通之，非徒无益而反害之。
按∶小便由于气化。书曰∶气化则能出矣。故补气生津，实至言也。膀胱藏津液之所，真阳不足，元气不升，
则不出矣。是补气填精为上。

凡是产后出现口燥咽干、口渴，同时伴有小便不通畅的情况，是因为失血导致阴血枯竭而多汗，加上劳累疲倦损伤了脾脏，脾不能为胃输送津液，导致生化气血的功能停滞，渗泄水液的指令无法执行。因此，上部没有津液流通，出现咽喉干燥、口渴的症状；下部则膀胱闭塞滞涩，出现水道不通的表现。治疗应当帮助脾脏、补益肺脏，调节气血的升降，使气血运行通畅，阳气上升、阴气下降，自然津液生成且二便通利。如果误认为口渴是火邪旺盛，而使用黄芩、黄连、知母、黄柏等药物来降火；误认为小便涩滞是水湿停滞，而使用五苓散等药物来通利，这不仅没有益处，反而会造成伤害。
按语：小便的通利依赖于气化功能。医书说：“气化则能出矣。”所以补气生津，确实是至理名言。膀胱是储藏津液的场所，如果真阳不足，元气不能上升，小便就无法排出。因此，补气填精是上策。

凡是产后小便频数的人，是因为腹内素有冷气，因身体虚弱而发作。适宜用桑螵蛸散，或者将益智仁炒熟研成粉末，用米汤送服二钱。如果小便淋漓作痛，也是由于产妇虚弱，冷气客居于腹中，用白茅根汤治疗。

Whenever postpartum dryness of the mouth and throat with thirst is accompanied by difficult urination, it is due to blood depletion causing excessive sweating, and fatigue injuring the Spleen, which fails to transport fluids for the Stomach. Consequently, the Qi of transformation and generation stagnates, and the directive for seepage and excretion does not function. Thus, there is no fluid circulation in the upper part, resulting in symptoms of dry throat and thirst; in the lower part, the Bladder is closed and stagnant, leading to obstruction of the water passages. Treatment should assist the Spleen and benefit the Lung, regulating the ascending and descending of Qi and Blood. When Qi and Blood circulate smoothly, Yang ascends and Yin descends, naturally generating fluids and facilitating smooth passage. If one mistakes thirst for excess Fire and uses Huangqin (Scutellariae Radix), Huanglian (Coptidis Rhizoma), Zhimu (Anemarrhenae Rhizoma), and Huangbai (Phellodendri Cortex) to descend it; or mistakes urinary retention for Water stagnation and uses Wu Ling San (Five-Ingredient Powder with Poria) to unblock it, this is not only ineffective but harmful.
Note: Urination depends on Qi transformation. The classic states: "When Qi transforms, it can be excreted." Therefore, tonifying Qi to generate fluids is indeed a profound truth. The Bladder is the residence where fluids are stored; if True Yang is insufficient and Yuan Qi does not ascend, excretion will not occur. Hence, tonifying Qi and filling Essence is the superior approach.
Zhu Pi Yi Fei Tang (Spleen-Assisting and Lung-Benefiting Decoction)
Huangqi (Astragali Radix, 1.5 qian) Renshen (Ginseng Radix et Rhizoma) Maidong (Ophiopogonis Tuber) [each 2 qian] Wuweizi (Schisandrae Fructus) [10 berries] Danggui (Angelicae Sinensis Radix, 2 qian) Fuling (Poria, 1.5 qian) Genge (Puerariae Radix, 1 qian)
Shengma (Cimicifugae Rhizoma, 0.4 qian) Zhigancao (Prepared Glycyrrhizae Radix et Rhizoma, 0.4 qian)
If sweating is excessive, add Zaoren (Ziziphi Spinosae Semen, 2 qian) and Mahuanggen (Ephedrae Caulis, 1 qian). If thirst is severe, use Shengmai San (Generating the Pulse Powder) as tea. If constipation occurs, add Rongrong (Cynomorii Herba, 2 qian). If the puerpera is robust with intense heat and difficult urination, temporarily add Zhimu (Anemarrhenae Rhizoma) and Huashi (Talcum, each 1 qian).
Whenever frequent urination occurs postpartum, it is due to pre-existing cold qi in the abdomen, triggered by deficiency. Sangpiaoxiao San (Mantis Egg Case Powder) is suitable, or Yizhiren (Alpiniae Oxyphyllae Fructus) can be stir-fried, powdered, and taken with rice water at a dose of 2 qian. If dribbling pain occurs, it is also due to puerperal weakness with cold qi lodging in the abdomen; treat with Baimaogen Tang (Imperatae Rhizoma Decoction).
