夫小儿大小便不通利者，《内经》曰∶三焦约也。约者，不行也。可用长流水煎
八正散，时时灌之，候大小便利即止也。
夫小儿久泻不止者，至八九月间，变为秋深冷痢，泄泻清白，时腹撮痛，乳瓣不
化。可用养脾丸，丸如黍米大，每服二、三十丸，米饮下，日三服则愈。若治刍荛之儿
，万举万全，富家且宜消息。
夫小儿通身浮肿，是水气肿也。小便不利者，通小便则愈。《内经》曰∶三焦闭
塞，水道不行。水满皮肤，身体痞肿，是风乘湿之症也。可用长流水加灯心，煎五苓散，时时
灌之；更于不透风暖处频浴，汗出则肿消，肿消则自愈，内外兼治故也。
夫小儿三、五岁时，或七、八岁至十余岁，发惊潮搐，涎如拽锯，不省人事，目
瞪喘急，将欲死者，《内经》曰∶此皆得于母胎中所授。悸惕怕怖，惊骇恐惧之气，故令小儿轻
者为惊吊，重者为痫病风搐，为腹中积热，为脐风。以上证候，可用吐涎及吐之药，如吐讫，
宜用朱、犀、脑、麝清凉坠涎之药。若食乳之子，母亦
宜服安魂定魄之剂，定志丸之类。如妇人怀孕之日，大忌惊忧悲泣，纵得子，必有诸疾。
夫小儿拗哭不止，或一、二日，或三、四日，乃邪祟之气凑于心，拗哭不止也。
有《藏经》一法∶以绵绢带缚手足讫，用三姓妇人净驴槽，卧小
儿于其中，不令旁人知而觑之，后移时则拗哭自止也。
小儿大小便不通畅的，根据《内经》所说，是三焦功能约束所致。所谓“约”，就是运行不畅的意思。可以用长流水煎煮八正散，频繁灌服，等到大小便通畅后就停止服用。
小儿长期腹泻不止的，到了八九月间，会转变为深秋寒性痢疾，排泄物清稀白色，时常腹部拘挛疼痛，乳汁凝结不化。可以使用养脾丸，药丸大小如黍米，每次服用二三十丸，用米汤送下，每日三次即可痊愈。如果用于治疗普通百姓家的孩子，往往百发百中；富贵人家也应当斟酌考虑使用。
小儿全身浮肿，这是水气肿。小便不利的，通利小便就能痊愈。《内经》说：三焦闭塞，水道不通。水液充满皮肤，身体痞满肿胀，这是风邪夹杂湿邪的病症。可以用长流水加灯心草，煎煮五苓散，频繁灌服；另外在不透风的温暖处频繁给小儿洗澡，出汗后肿胀就会消退，肿胀消退后自然痊愈，这是因为内外兼治的缘故。
小儿在三、五岁时，或者七、八岁到十几岁时，出现惊厥抽搐，喉间痰声如拉锯，神志不清，眼睛瞪大喘息急促，快要死去的，《内经》说：这些症状都是由于在母胎中受到惊吓恐惧之气所致。这种悸动、警惕、害怕、惊恐的情绪，导致小儿轻者称为惊吊，重者称为痫病风搐，或者是腹中积热，或者是脐风。以上证候，可以使用催吐涎液的药物，如吐完后，适宜使用朱砂、犀角、冰片、麝香等具有清凉坠痰作用的药物。如果是吃奶的婴儿，母亲也应当服用安魂定魄的药物，如定志丸之类。如果妇女在怀孕之日，非常忌讳受惊忧愁悲伤哭泣，即使生下孩子，也必定会有各种疾病。
小儿哭闹不止，或一两天，或三四天，这是邪祟之气侵袭心脏，导致哭闹不止。有《藏经》中的一法：用棉绢带子绑缚住小儿的手脚，找三个不同姓氏的妇人洗净的驴槽，让小儿躺在里面，不让旁人知道并窥视，过一段时间后，哭闹自然会停止。
For infants and children with unsmooth urination and defecation, the *Neijing* states: this is due to the constraint of the Sanjiao (Triple Burner). "Constraint" implies impaired function. One may use Changliushui (Long-flowing water) to decoct Bazheng San (Eight-Positive Powder), administering it frequently until urination and defecation become smooth, then stopping.
For infants and children with prolonged diarrhea that does not cease, by August or September, it may transform into late-autumn cold dysentery, characterized by clear, white stools, occasional abdominal cramping pain, and undigested milk curds. Yangpi Wan (Spleen-Nourishing Pill) can be used; pills should be sized like millet seeds, with a dosage of 20–30 pills per administration, taken with rice drink, three times daily for recovery. This method is highly effective for commoners; wealthy families should also consider its application.
Generalized edema in infants and children is referred to as Shuiqi Zhong (Water-Qi Edema). If accompanied by difficult urination, promoting urination will lead to recovery. The *Neijing* states: when the Sanjiao is blocked and water pathways fail to circulate, water fills the skin, causing bodily bloating and swelling. This is a syndrome of Wind invading Dampness. One may add Dengxincao (Juncus Effusus Herb) to Changliushui to decoct Wuling San (Five-Ingredient Powder with Poria), administering it frequently. Additionally, frequent bathing in a warm, draft-free place will induce sweating, leading to the reduction of edema and spontaneous recovery, due to combined internal and external treatment.
When infants aged three to five, or children aged seven to ten-plus years old, experience convulsions and tidal spasms, with phlegm sounds resembling sawing, loss of consciousness, staring eyes, rapid breathing, and impending death, the *Neijing* states: these conditions originate from fright and fear qi received in the womb. Such palpitations, alertness, fear, and terror cause mild cases to be termed Jingdiao (Fright-Hanging), while severe cases are termed Xianbing Fengchu (Epilepsy with Wind-Spasm), or indicate Abdominal Accumulated Heat, or Qifeng (Umbilical Wind). For these syndromes, emetic medicines for phlegm can be used. After vomiting, cooling and descending-phlegm medicines such as Zhusha (Cinnabar), Xijiao (Rhinoceros Horn - *Note: Substitute with legal alternatives in modern practice*), Bingpian (Borneol), and Shexiang (Musk) are appropriate. For nursing infants, the mother should also take Anhun Dingpo (Soul-Calming and Spirit-Stabilizing) formulas, such as Dingzhi Wan (Willpower-Stabilizing Pill). Women during pregnancy must strictly avoid fright, worry, sorrow, and weeping; otherwise, even if they give birth, the child will likely suffer from various diseases.
Persistent crying and wailing in infants, lasting one to two days or three to four days, is caused by evil spirit qi gathering in the Heart. There is a method in the *Zangjing*: bind the infant's hands and feet with cotton silk strips, place the infant in a clean donkey trough washed by women of three different surnames, ensure no bystanders know or peek, and after some time, the persistent crying will naturally cease.
