小儿寒淋，皆因风寒乘入膀胱，致下焦受冷，遂成寒淋，其候小便闭塞，胀痛难禁，不时淋漓，少腹隐痛，
古法主五苓散倍加肉桂小茴香治之（如土炒白术、泽泻、猪苓、肉桂、小茴香、赤茯苓等味）。
〔真按〕小儿寒邪袭入膀胱，欲治其淋，即当先祛其寒，既不能以麻黄祛膀胱之寒，亦不能以苓泽泻膀胱
之热，盖膀胱本无热而仅有寒，方用上肉桂三分，小茴香一钱，细木通八分，荔枝核钱半，赤小豆钱半，赤茯苓
一钱，引用生姜皮三分。
小儿热淋，因膀胱蓄热而成，其候小便不通，淋漓涩痛，古法主十味导赤汤（如生地、山栀子、木通、瞿
麦、滑石、淡竹叶、茵陈蒿、黄芩、生甘草、猪苓等共十味）。
〔真按〕小儿热淋，遽用十味，未免过剂，但用细生地二钱，小木通一钱，寸麦冬一钱，车前子一钱，淡
竹叶一钱，生甘草梢三分，引用灯芯三十寸，虚者加西洋参五分。
小儿石淋，逢溺则茎中作痛，常带砂石之状，因膀胱蓄热日久所致，正如汤瓶久经火炼，底结白 也，轻者
古法主葵子散（如炒桑皮、瞿麦、栀子、赤茯苓、木通、车前子、炙甘草、葵子等味），重者古法主八正散（如
蓄、瞿麦、滑石、木通、赤苓、车前子、生大黄、生栀子，引用灯芯）。
〔真按〕小儿热结膀胱，日久始至成淋，下如砂石，亦由平日失治，今治之亦不为晚，方用生地黄二钱，大
木通一钱，川黄连五分，飞滑石三钱，赤茯苓钱半，生甘草梢五分，引用鲜竹叶十五片，灯芯十茎。
重者加生锦纹六分。
小儿寒淋，都是由于风寒之邪侵入膀胱，导致下焦受冷，从而形成寒淋。其症状表现为小便闭塞不通，胀痛难以忍受，不时淋漓不尽，少腹部隐隐作痛。
古代医法主要使用五苓散并加倍加入肉桂和小茴香来治疗（药物包括土炒白术、泽泻、猪苓、肉桂、小茴香、赤茯苓等）。
〔陈守真按语〕小儿寒邪侵袭膀胱，想要治疗淋证，就应当先祛除寒邪。既不能用麻黄来祛除膀胱的寒邪，也不能用茯苓和泽泻来清除膀胱的热邪，因为膀胱本身没有热邪，仅有寒邪。方剂用上肉桂三分，小茴香一钱，细木通八分，荔枝核一钱半，赤小豆一钱半，赤茯苓一钱，煎药时引用生姜皮三分。
小儿热淋，是由于膀胱蓄积热邪而形成的。其症状表现为小便不通畅，淋漓涩痛。古代医法主要使用十味导赤汤（药物包括生地、山栀子、木通、瞿麦、滑石、淡竹叶、茵陈蒿、黄芩、生甘草、猪苓等共十味）。
〔陈守真按语〕小儿热淋，如果立即使用十味导赤汤全方，未免药量过重。只使用细生地二钱，小木通一钱，寸麦冬一钱，车前子一钱，淡竹叶一钱，生甘草梢三分，煎药时引用灯芯三十寸；体质虚弱者加西洋参五分。
小儿石淋，排尿时尿道中疼痛，常带有砂石样的物质。这是由于膀胱蓄积热邪日久所致，就像汤瓶长时间经过火烤，底部结出白色水垢一样。病情较轻者，古代医法主要使用葵子散（药物包括炒桑皮、瞿麦、栀子、赤茯苓、木通、车前子、炙甘草、葵子等）；病情较重者，古代医法主要使用八正散（药物包括萹蓄、瞿麦、滑石、木通、赤茯苓、车前子、生大黄、生栀子，煎药时引用灯芯）。
〔陈守真按语〕小儿热邪结聚在膀胱，日久才形成淋证，排出物如砂石，这也是由于平日失治造成的，现在进行治疗也不算晚。方剂使用生地黄二钱，大木通一钱，川黄连五分，飞滑石三钱，赤茯苓一钱半，生甘草梢五分，煎药时引用鲜竹叶十五片，灯芯十茎。病情重者加生锦纹（生大黄）六分。
Pediatric cold lin (cold strangury) is caused by wind-cold pathogens invading the Bladder, leading to cold in the Lower Jiao, thereby forming cold lin. The manifestations include urinary obstruction, unbearable distending pain, frequent dribbling, and dull pain in the lower abdomen.
Ancient methods primarily treated this with Wu Ling San (Five-Ingredient Powder with Poria) with increased doses of Rou Gui (Cinnamon Twig) and Xiao Hui Xiang (Fennel). The ingredients included Tu Chao Bai Zhu (Earth-fried Atractylodis Rhizoma), Ze Xie (Alismatis Rhizoma), Zhu Ling (Polyporus), Rou Gui (Cinnamon Twig), Xiao Hui Xiang (Fennel), Chi Fu Ling (Red Poria), etc.
[Chen Shouzhen's Note] When pediatric cold pathogens invade the Bladder, to treat lin, one must first dispel the cold. Neither Ma Huang (Ephedrae Herba) can be used to dispel cold from the Bladder, nor Fu Ling (Poria) and Ze Xie (Alismatis Rhizoma) to clear heat from the Bladder, because the Bladder inherently lacks heat and possesses only cold. The prescription uses Shang Rou Gui (Cortex Cinnamomi) 3 fen, Xiao Hui Xiang (Foeniculi Fructus) 1 qian, Xi Mu Tong (Akebiae Caulis) 8 fen, Li Zhi He (Litchi Seed) 1.5 qian, Chi Xiao Dou (Adzuki Bean) 1.5 qian, Chi Fu Ling (Poria) 1 qian, with Sheng Jiang Pi (Zingiberis Pericarpium) 3 fen as a guiding drug.
Pediatric hot lin (hot strangury) is formed due to heat accumulation in the Bladder. Its manifestations include urinary retention, dribbling, and painful dysuria. Ancient methods primarily treated this with Shi Wei Dao Chi Tang (Ten-Ingredient Decoction to Guide Out Heat from the Heart). The ingredients included Sheng Di Huang (Rehmanniae Radix), Shan Zhi Zi (Gardeniae Fructus), Mu Tong (Akebiae Caulis), Qu Mai (Dianthi Herba), Hua Shi (Talcum), Dan Zhu Ye (Lophatheri Herba), Yin Chen Hao (Artemisiae Scopariae Herba), Huang Qin (Scutellariae Radix), Sheng Gan Cao (Glycyrrhizae Radix et Rhizoma), and Zhu Ling (Polyporus), totaling ten ingredients.
[Chen Shouzhen's Note] For pediatric hot lin, using the full ten-ingredient formula immediately may result in an excessive dose. Instead, use Xi Sheng Di Huang (Rehmanniae Radix Preparata) 2 qian, Xiao Mu Tong (Akebiae Caulis) 1 qian, Cun Mai Dong (Ophiopogonis Tuber) 1 qian, Che Qian Zi (Plantaginis Semen) 1 qian, Dan Zhu Ye (Lophatheri Herba) 1 qian, Sheng Gan Cao Shao (Tip of Glycyrrhizae Radix et Rhizoma Raw) 3 fen, with Deng Xin (Typhae Stamen) 30 cun as a guiding drug. For deficiency cases, add Xi Yang Shen (American Ginseng Radix et Rhizoma) 5 fen.
Pediatric stone lin (stone strangury) presents with pain in the urethra during urination and the passage of sand-like stones. This is caused by long-term heat accumulation in the Bladder, similar to how a kettle develops white scale at the bottom after prolonged heating over fire. For mild cases, ancient methods primarily used Kui Zi San (Abutiloni Seed Powder). The ingredients included Chao Sang Bai Pi (Mori Cortex), Qu Mai (Dianthi Herba), Zhi Zi (Gardeniae Fructus), Chi Fu Ling (Poria), Mu Tong (Akebiae Caulis), Che Qian Zi (Plantaginis Semen), Zhi Gan Cao (Honey-fried Glycyrrhizae Radix et Rhizoma), and Kui Zi (Abutiloni Semen). For severe cases, ancient methods primarily used Ba Zheng San (Eight-Ingredient Powder for Rectification). The ingredients included Bian Xu (Polygoni Avicularis Herba), Qu Mai (Dianthi Herba), Hua Shi (Talcum), Mu Tong (Akebiae Caulis), Chi Fu Ling (Poria), Che Qian Zi (Plantaginis Semen), Sheng Da Huang (Rhei Radix et Rhizoma Raw), Sheng Zhi Zi (Gardeniae Fructus Raw), with Deng Xin (Typhae Stamen) as a guiding drug.
[Chen Shouzhen's Note] Pediatric heat binding in the Bladder leads to lin only after a long period, with discharge resembling sand and stones. This results from previous lack of proper treatment; treating it now is not too late. The prescription uses Sheng Di Huang (Rehmanniae Radix) 2 qian, Da Mu Tong (Akebiae Caulis) 1 qian, Chuan Huang Lian (Coptidis Rhizoma) 5 fen, Fei Hua Shi (Prepared Talcum) 3 qian, Chi Fu Ling (Poria) 1.5 qian, Sheng Gan Cao Shao (Tip of Glycyrrhizae Radix et Rhizoma Raw) 5 fen, with Xian Zhu Ye (Fresh Lophatheri Herba) 15 leaves and Deng Xin (Typhae Stamen) 10 stems as guiding drugs. For severe cases, add Sheng Jin Wen (Raw Rhei Radix et Rhizoma) 6 fen.
