岭北李文卿，病两膝膑屈伸有声剥剥然。或以为骨鸣。戴人曰∶非也。骨不戛，
焉能鸣？此筋湿也。湿则筋急。有独缓者，缓者不鸣，急者鸣也。若用予之药，一涌一泄，
上下去其水，水去则自无声矣。李文卿乃从其言，既而果然矣。
息城李左衙之妻，病白带如水，窈满中绵绵不绝，秽臭之气不可近，面黄食减，
已三年矣。诸医皆云积冷，起石、硫黄、姜、附之药，重重燥补，污水转多，常以 ，
日易数次。或一药以木炭十斤，置药在坩埚中，盐泥封固，三日三
不绝，烧令通赤，名曰火龙丹。服至数升，污水弥甚。
艾烧针，三年之间，不可胜数。戴人断之曰∶此带浊水。本热乘太阳经，其寒水不可胜如此
也。夫水自高而趋下，宜先绝其上源。乃涌痰水二、三升，次日下沃水十余行，三遍，汗出
周身。至明旦，病患云∶污已不下矣。次用寒凉之剂，服及半载，产一子。《内经》曰∶少
热，溲出白液。带之为病，溶溶然若坐水中。故治带下同治湿法，泻痢，皆宜逐水利小溲。
勿以赤为热，白为寒。今代刘河间书中言之详矣。
赵君玉妻病嗽，时已十月矣。戴人处方六味；陈皮、当归、甘草、白术、枳壳、桔梗。君玉
疑其不类嗽药。戴人笑曰∶君怪无乌梅、罂粟壳乎？夫冬嗽，乃秋之湿也。湿土逆而为嗽
，此方皆散气除湿，解急和经。三服帖然效矣。
Li Wenqing from Lingbei suffered from a condition where his patellae made a "pop-pop" sound upon flexion and extension of both knees. Some believed it was bone grinding. Dairen (Zhang Congzheng) said: Incorrect. If bones do not rub against each other, how can they make noise? This is due to dampness affecting the sinews. Dampness causes sinew tension. Where there is slackness, there is no noise; only where there is tension does noise occur. If you use my medicine, employing vomiting and purging methods to remove water from above and below, once the water is eliminated, the sound will naturally cease. Li Wenqing followed his advice, and indeed, he recovered subsequently.
The wife of Li Zuo Ya from Xicheng suffered from leukorrhea resembling clear water, flowing continuously within the vagina with a foul odor that was unbearable. Her face was sallow, her appetite diminished, and this had persisted for three years. All physicians claimed it was accumulated cold, prescribing drugs such as Hemaetites (Lithogypsi Fibrosum), Sulfur, Zingiberis Rhizoma (Dried Ginger), and Aconiti Lateralis Radix Praeparata (Prepared Fuzi). They repeatedly used dry and warm tonics, yet the discharge increased, requiring her to change linens several times a day. One prescription involved placing ten catties of charcoal in a crucible, putting the herbs inside, sealing it with salt mud, and firing it continuously for three days and nights until red-hot, named "Fire Dragon Pill." After consuming several sheng, the discharge worsened significantly. Between moxibustion and cauterization needles, treatments were countless over three years. Dairen diagnosed: This is turbid water in the Dai Mai (Girdle Vessel). Originally, heat pathogen invaded the Taiyang Channel, causing cold water to overflow uncontrollably. Water flows from high to low; one must first cut off its upper source. He first induced vomiting to expel two or three sheng of phlegm-water, then purged more than ten times the next day to evacuate watery stool. After three rounds, profuse sweating occurred all over the body. By the next morning, the patient reported: The turbid discharge has stopped. Subsequently, cold-natured formulas were administered for half a year, resulting in the birth of a child. The *Neijing* states: Heat in the lower jiao causes white fluid to exit via urination. The disease of Dai Mai presents as feeling as if sitting in water. Therefore, treating Dai Mai follows the same method as treating dampness; for dysentery and diarrhea, promoting diuresis and increasing urine output are appropriate. Do not assume red indicates heat and white indicates cold. Liu Hejian’s books have discussed this in detail.
The wife of Zhao Junyu suffered from coughing in the tenth month. Dairen prescribed six ingredients: Chenpi (Aged Tangerine Peel), Danggui (Angelica Sinensis), Gancao (Licorice Root), Baizhu (Atractylodes Macrocephala), Zhike (Bitter Orange), and Jiegeng (Platycodon Root). Junyu doubted these were typical cough medicines. Dairen laughed and said: Are you surprised by the absence of Wumei (Mume Fruit) and Ying Susu Qiao (Poppy Shell)? Winter coughs stem from autumnal dampness. Damp-earth qi rebelling upward causes coughing. This formula disperses qi, removes dampness, relieves urgency, and harmonizes the channels. After three doses, the condition resolved effectively.
