小儿腹内有虫，口馋好甜，喜食泥土茶叶木炭之类。古法主槟榔丸以攻之（如小槟榔一两，南木香五钱，
鹤虱子五钱，光贯众五钱，广锡灰五钱，陈漆渣二钱，烧灰，正轻粉二钱，白雷丸二钱，巴豆霜二钱，以漆楂灰
同众药研为细末，醋煮面糊为丸）。麻子大，每服二十丸，五更苦楝皮煎汤下。
〔真按〕小儿肠有湿热，宜用苦寒引导小肠。方以苦楝皮、北秦皮、槐角子、胡粉、黄柏、牡蛎各等分，
猪肚肠一只，漂净煮丸，量儿大小与之。
虫下后，以黄连、神曲、木香、槟榔、肉豆蔻、使君子、麦芽各等分为丸，调补其脾。
小儿虫自溺窍而出，因湿伤脾胃，下注小肠，粪溏完谷，不宜温补，方用黄柏八分，茯苓钱半，猪苓钱半，
槐米一钱，泽泻钱半，川萆 八分。
小儿前阴主气，后阴主血。盖膀胱之津液，血所化也，由气而后能出，太阴之传送，气之运也，由血而后能
润，此便溺之流通，即气血之根据附。血不化，气不运，则二便秘结。古法主八正散（如淮木通、白滑石、黑栀子、
车前子、巨麦穗、锦庄黄、生条芩。七味煎极熟，以芒硝冲服）。
〔真按〕小儿二便秘结，先用外导之法，以香油半盏，调芒硝一钱、皂角末少许。装贮玻璃器管内，插谷道
中，将调匀之油徐徐送入，少顷大便即通。内以玄明粉钱半，滑石粉二钱，生白蜜半两，白滚水冲服，则二便皆
通畅矣。
小儿腹内有虫，表现为嘴馋喜食甜食，喜欢吃泥土、茶叶、木炭等异物。古法主张用槟榔丸来攻杀虫积（配方如：小槟榔一两，南木香五钱，鹤虱子五钱，光贯众五钱，广锡灰五钱，陈漆渣二钱烧成灰，正轻粉二钱，白雷丸二钱，巴豆霜二钱，将漆渣灰与其他药物研为细末，用醋煮面糊作为粘合剂制成丸药）。丸药大小如麻子，每次服用二十丸，在凌晨五更天时，用苦楝皮煎汤送服。
〔陈守真按语〕小儿肠道有湿热，适宜使用苦寒性质的药物引导病邪从小肠排出。方剂由苦楝皮、北秦皮、槐角子、胡粉、黄柏、牡蛎各等分组成，取一只猪肚肠，漂洗干净后与药同煮，制成丸药，根据患儿年龄大小给予服用。
虫子排出后，用黄连、神曲、木香、槟榔、肉豆蔻、使君子、麦芽各等分制成丸药，以调理补益脾胃。
小儿体内的虫从尿道口排出，这是因为湿气损伤了脾胃，向下流注到小肠，导致大便稀溏且含有未消化的食物残渣，此时不宜使用温补法，方剂用黄柏八分，茯苓一钱半，猪苓一钱半，槐米一钱，泽泻一钱半，川萆薢八分。
小儿前阴（尿道）主要关联气机，后阴（肛门）主要关联血液。膀胱的津液是由血化生的，依靠气的推动才能排出；太阴脾经的传导功能，依靠气的运化，依靠血的滋润才能通畅。这就是二便流通的基础在于气血的依附关系。如果血不能化生，气不能运化，就会导致大小便便秘不通。古法主张用八正散（配方如：淮木通、白滑石、黑栀子、车前子、巨麦穗、锦庄黄、生条芩。七味药煎煮至极熟，加入芒硝冲服）。
〔陈守真按语〕小儿出现大小便便秘不通，先用外导法治疗，取香油半盏，调入芒硝一钱、少许皂角末。装入玻璃管中，插入肛门内，将调匀的油徐徐送入，过一会儿大便即可通畅。内部用药用玄明粉一钱半，滑石粉二钱，生白蜜半两，用开水冲服，这样大小便都能通畅了。
When parasites reside in a child's abdomen, the child may exhibit cravings for sweets and a preference for eating non-food items such as soil, tea leaves, or charcoal. Ancient methods primarily advocate using *Binglang Wan* (Areca Seed Pill) to attack and expel them (e.g., Xiao Binglang [Small Areca Seed] 1 liang, Nan Muxiang [Southern Costus Root] 5 qian, Heshizi [Chrysanthemum Carrot Seed] 5 qian, Guang Guanzhong [Polygonatum Rhizome] 5 qian, Guang Xihui [Tin Ash] 5 qian, Chen Qizha [Old Lac Residue] 2 qian, burnt to ash, Zheng Qingfen [Calomel] 2 qian, Bai Leiwang [Albizia Seed] 2 qian, Badoushuang [Croton Seed Frost] 2 qian; grind the lac residue ash with other medicines into fine powder, use vinegar-boiled wheat paste as a binder to form pills). The pills should be the size of hemp seeds. Administer 20 pills per dose, taken at the third watch (around 1-3 AM) with a decoction of Kuanlianpi [Cortex Dictamni].
[Chen Shouzhen’s Note:] When damp-heat exists in a child's intestines, it is appropriate to use bitter-cold herbs to guide the pathogen out through the Small Intestine. The formula consists of equal parts of Kuanlianpi [Cortex Dictamni], Bei Qinpi [Cortex Fraxini], Huaijiaozi [Gleditsia Fruit], Fufen [Lead Carbonate], Huangbai [Phellodendron Bark], and Muli [Oyster Shell]. Take one pig intestine, clean it thoroughly, boil it with the herbs, and form pills. Administer according to the child's age and size.
After the parasites are expelled, use equal parts of Huanglian [Coptis Rhizome], Shenqu [Medicated Leaven], Muxiang [Aucklandiae Radix], Binglang [Areca Seed], Roudoukou [Nutmeg], Shijunzi [Quisqualis Fruit], and Maiya [Malt] to form pills, thereby regulating and tonifying the Spleen.
If parasites exit through the urethra, it is due to dampness injuring the Spleen and Stomach, flowing downward into the Small Intestine, resulting in loose stools with undigested food particles. In this case, warming and tonifying methods are contraindicated. Use a formula of Huangbai [Phellodendron Bark] 8 fen, Fuling [Poria] 1.5 qian, Zhuling [Polyporus] 1.5 qian, Huaimi [Sophora Flower Bud] 1 qian, Zexie [Alisma Rhizome] 1.5 qian, and Chuan Bixie [Dioscorea Hypoglauca Rhizome] 8 fen.
The anterior yin (urethra) is primarily governed by Qi, while the posterior yin (anus) is primarily governed by Blood. The fluids of the Bladder are transformed from Blood and require the movement of Qi to be excreted. The transportation function of the Taiyin (Spleen) relies on the movement of Qi and requires the moistening of Blood to function smoothly. This smooth flow of urination and defecation is based on the attachment and interaction of Qi and Blood. If Blood fails to transform and Qi fails to move, both urine and stool will become constipated. Ancient methods primarily advocate using *Bazheng San* (Eight-Herb Corrective Powder) (e.g., Huai Mutong [Akebia Stem], Bai Huashi [Talcum], Hei Zhizi [Gardenia Fruit], Cheqianzi [Plantago Seed], Jumaifeng [Barley Ear], Jin Zhuanghuang [Rhubarb], Sheng Tiaoqin [Scutellaria Root]. Decoct the seven ingredients until very soft, add Mangxiao [Mirabilite] and take with the liquid).
[Chen Shouzhen’s Note:] For children suffering from constipation of both urine and stool, first employ an external guiding method: mix half a zhan of sesame oil with 1 qian of Mangxiao [Mirabilite] and a small amount of Zaorao [Gleditsia Sinensis Fruit] powder. Load this mixture into a glass tube, insert it into the anus, and slowly inject the mixed oil. After a short while, bowel movements will become unobstructed. Internally, administer Xuanmingfen [Refined Mirabilite] 1.5 qian, Huashifen [Talcum Powder] 2 qian, and raw white honey 0.5 liang, dissolved in boiling water. This will ensure the free passage of both urine and stool.
