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，
则生化之元气不运，渗泄之令不行，是以上无津液流通，而有咽干燥渴之症，下则胃肾闭滞
，而有水道不通之候，治当助脾益肺，升其血气，则血气流行，阳升阴降，自然津生而便利
矣。若认口渴为火，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。
助脾益肺汤∶黄 一钱五分，人参、麦冬各二钱，五味十粒，当归二钱，茯苓一钱五分
，干葛一钱，升麻四分，炙甘草五分。汗多，加枣仁二钱，麻黄根一钱。渴甚，生脉散代茶
。大便不通，加苁蓉二钱。如产母壮盛而热剧、小便不利者，暂加知母、滑石各一钱。
凡产后小便数者，由腹内宿有冷气，因虚而发。宜桑螵蛸散，或以益智仁炒研为末，米
饮下二钱。若淋沥作痛，亦由产母虚弱，冷气客于腹中，以茅根汤治之。
桑螵蛸散∶螵蛸十二枚，人参三两，黄 三两，鹿茸、牡蛎、赤石脂各二两，共为末，
米饮汤空心下。
白茅根汤∶白茅根、瞿麦、茯苓、车前、人参、滑石、通草、麦冬、炙甘草。加灯芯数

又，内府秘方∶用陈米淘浓泔，澄清，热服之，小便即通。
按∶治血淋，可加怀牛膝。
凡是产后出现口燥咽干且口渴，同时伴有小便不利的症状，这是由于血液枯竭导致多汗，加上劳累疲倦损伤了脾脏，脾不能为胃传输津液。因此，生化元气的运行受阻，渗泄的功能无法行使，所以上部没有津液流通，出现咽喉干燥、口渴的症状；下部则因胃和肾闭滞，出现水道不通的情况。治疗应当帮助脾脏、补益肺脏，提升气血，使得气血流行，阳气上升、阴气下降，自然津液生成而二便通利。如果误认为口渴是火邪所致，而使用黄芩、黄连、知母、黄柏等药物来降火，或者认为小便涩滞是水湿停滞，而使用五苓散等药物来通利，这不仅无益，反而有害。
助脾益肺汤：黄芪一钱五分，人参、麦冬各二钱，五味子十粒，当归二钱，茯苓一钱五分，干葛（葛根）一钱，升麻四分，炙甘草五分。如果出汗多，加酸枣仁二钱，麻黄根一钱。如果口渴严重，用生脉散代替茶饮用。如果大便不通，加肉苁蓉二钱。如果产妇体质强壮但热势剧烈、小便不利，暂时加知母、滑石各一钱。
凡是产后小便频数的，是由于腹内素有冷气，因为身体虚弱而发作。适宜用桑螵蛸散，或者将益智仁炒熟研成粉末，用米饮送服二钱。如果淋沥作痛，也是由于产妇虚弱，冷气客居于腹中，用白茅根汤治疗。
桑螵蛸散：螵蛸十二枚，人参三两，黄芪三两，鹿茸、牡蛎、赤石脂各二两，共研为细末，空腹时用米饮汤送服。
白茅根汤：白茅根、瞿麦、茯苓、车前子、人参、滑石、通草、麦冬、炙甘草。加入灯芯草数根煎煮服用。
另外，内府秘方：用陈年大米淘洗出的浓米泔水，澄清后，趁热服用，小便即可通畅。
按语：治疗血淋，可以加怀牛膝。
In cases where postpartum dryness of the mouth and throat with thirst is accompanied by difficult urination, it is due to blood depletion causing excessive sweating, combined with fatigue and overwork damaging the Spleen. The Spleen fails to transport fluids for the Stomach, resulting in impaired circulation of Yuan Qi (Original Qi) generated from digestion and failure of the diffusing and descending functions. Consequently, there is a lack of fluid circulation in the upper body, leading to symptoms of dry throat and thirst; while in the lower body, stagnation of the Stomach and Kidney leads to obstruction of the water passages. Treatment should focus on assisting the Spleen and benefiting the Lung, raising Blood and Qi. Once Blood and Qi circulate freely, Yang rises and Yin descends, naturally generating fluids and facilitating smooth excretion. If one mistakenly attributes thirst to Fire and uses Huang Qin (Scutellaria Root), Huang Lian (Coptis Rhizome), Zhi Mu (Anemarrhena Rhizome), and Huang Bo (Phellodendron Bark) to clear heat downward, or treats urinary retention as Water stagnation using Wu Ling San (Five-Ingredient Powder with Poria) to promote diuresis, such approaches are not only ineffective but harmful.
Zhu Pi Yi Fei Tang (Assist Spleen Benefit Lung Decoction): Huang Qi (Astragalus Root) 1.5 qian, Ren Shen (Ginseng Radix et Rhizoma) and Mai Dong (Ophiopogon Tuber) each 2 qian, Wu Wei Zi (Schisandra Fruit) 10 berries, Dang Gui (Angelica Sinensis Radix) 2 qian, Fu Ling (Poria) 1.5 qian, Gan Ge (Puerariae Radix) 1 qian, Sheng Ma (Cimicifugae Rhizoma) 4 fen, Zhi Gan Cao (Honey-fried Licorice Root) 5 fen. For excessive sweating, add Zao Ren (Ziziphus Seed) 2 qian and Ma Huang Gen (Ephedrae Herba Cum Caulice) 1 qian. For severe thirst, use Sheng Mai San (Generate the Pulse Powder) as tea substitute. For constipation, add Rong Ren (Cistanche Stem) 2 qian. If the parturient is robust but suffers from intense heat and difficult urination, temporarily add Zhi Mu (Anemarrhena Rhizome) and Hua Shi (Talcum) each 1 qian.
In cases of frequent urination after childbirth, it is caused by pre-existing cold qi in the abdomen manifesting due to deficiency. Sang Piao Xiao San (Mantis Egg-case Powder) is appropriate, or one may grind Yi Zhi Ren (Alpinia Oxyphylla Fruit) into powder and take 2 qian with rice water. If dysuria with pain occurs, it is also due to maternal weakness allowing cold qi to lodge in the abdomen; Bai Mao Gen Tang (Imperata Rhizome Decoction) should be used.
Sang Piao Xiao San: Sang Piao Xiao (Mantis Egg-case) 12 pieces, Ren Shen (Ginseng Radix et Rhizoma) 3 liang, Huang Qi (Astragalus Root) 3 liang, Lu Rong (Deer Antler without Horn) and Mu Li (Oyster Shell) and Chi Shi Zhi (Red Halloysite) each 2 liang. Grind all into fine powder. Take orally with rice water on an empty stomach.
Bai Mao Gen Tang (Imperata Rhizome Decoction): Bai Mao Gen (Imperata Rhizome), Qu Mai (Dianthus Herba), Fu Ling (Poria), Che Qian Zi (Plantago Seed), Ren Shen (Ginseng Radix et Rhizoma), Hua Shi (Talcum), Tong Cao (Tetrapanacis Medulla), Mai Dong (Ophiopogon Tuber), Zhi Gan Cao (Honey-fried Licorice Root). Add a few stems of Deng Xin Cao (Junci Medulla) and decoct for administration.
Additionally, an Imperial Secret Recipe: Use thick wash water from aged rice, clarify it, and drink it hot; urination will immediately flow smoothly.
Note: For treatment of Xue Lin (Blood Strangury), add Huai Niu Xi (Achyranthes Bidentata Root).
