小儿脱肛源于肺气虚弱，治疗应首选补中益气汤；若伴有肿胀、坚硬且疼痛，则需清除积热，使用脏连丸。
【注】此证是由于小儿气虚，导致肛门脱出体外，应用补中益气汤加入羌活、白芍、煨姜来主治。如果出现肿胀、坚硬和疼痛的症状，说明体内有湿热，应当使用清热除湿的方剂进行治疗；如果发生脏毒（一种因湿热蕴结肠道引起的肛肠疾病），导致肛门翻出，则以脏连丸为主治方药。外治法可用五倍子、老葱头、朴硝煎汤清洗患处。肿胀处涂抹坎宫锭子，均有效。

肛门瘙痒是由虫蚀引起，下唇必然出现小白疮，内服九味芦荟丸，外用铜绿与雄黄粉末撒敷。
【注】此证表现为小儿肛门瘙痒，是由寄生虫侵蚀所致。观察其下唇内部，必定生有小白疮；或者在耳朵前后，结成如串珠状的小结节。医书说：“下唇有疮，是虫蚀肛门之象。”适宜服用芦荟丸。外用雄黄、铜绿等分研为细末，撒于患处即刻见效。

先天遗毒在胎儿时期就已形成，分为禀受（遗传）和染受（感染）两种情况。无皮肤保护、全身赤红的病情不易痊愈；肌肤出现红点随后转为斑烂，若是后天感染尚可治愈，若是先天禀受毒邪则难以治疗。
【注】此证系先天遗毒于胞胎，有禀受（遗传自父母）和染受（后天感染）之分。禀受者，由父母先患杨梅疮（梅毒），而后怀孕生子，婴儿出生后，则周身色赤无皮，毒邪攻冲九窍，导致腐烂斑烂，患此病难愈，百无一人生还。染受者，乃先怀孕，父母后患杨梅疮，毒气传于胎中，婴儿出生后，则头上出现坑凹，肌肤先出红点，随后发烂斑，严重者毒邪攻冲口角、眼眶、耳鼻及前阴、肛门破烂。初期宜用人中黄细末三五分，用土茯苓煎汤调成稠状，每日服用二三次。肿胀处用太乙紫金锭水磨涂敷。破烂处用黄柏蜜炙后研末撒敷，干燥时用香油调和搽擦。服药见效后，后续服用二黄散，十人中可保三四存活。若毒邪蔓延遍身，日夜啼哭不止，不吃乳食，属于毒邪极盛而正气微弱，最终难以救治。

Infant prolapse of the rectum originates from deficiency of Lung Qi; Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) should be used first. If accompanied by swelling, induration, and pain, accumulated heat must be cleared, using Zang Lian Wan (Intestine-Coating Pill).
[Note] This condition is caused by Qi deficiency in infants, resulting in the protrusion of the anus outside the body. It should be treated with Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) added with Qiang Huo (Notopterygii Rhizoma et Radix), Bai Shao (Radix Paeoniae Alba), and Wei Jiang (Prepared Ginger Rhizome). If symptoms include swelling, induration, and pain, it indicates damp-heat within the interior; a formula that clears heat and removes dampness should be administered. If Zang Du (Visceral Toxin, a type of anal disease caused by damp-heat accumulation in the intestines) occurs, causing the anus to evert, Zang Lian Wan (Intestine-Coating Pill) is the primary treatment. For external treatment, wash the area with a decoction of Wu Bei Zi (Galla Chinensis), Lao Cong Tou (Allii Fistulosi Bulbus), and Xiao Ming Xiao (Mirabilite Natrii Sulfatis Crystal). Apply Kan Gong Ding Zi (Kan Palace Plaster) to the swollen area; both methods are effective.

Anal pruritus is caused by parasitic erosion; small white sores will inevitably appear on the lower lip. Administer Jiu Wei Lu Hui Wan (Nine-Ingredient Aloe Vera Pill) internally, and externally sprinkle powder made of Tong Lv (Malachite) and Xiong Huang (Realgar).
[Note] This condition manifests as anal pruritus in infants, caused by parasitic erosion. Observe the inside of the lower lip; small white sores will definitely appear. Alternatively, small nodules resembling a string of beads may form before and behind the ears. Medical texts state: "Sores on the lower lip indicate parasitic erosion of the anus." It is appropriate to administer Lu Hui Wan (Aloe Vera Pill). Externally, grind Xiong Huang (Realgar) and Tong Lv (Malachite) into equal parts of fine powder and apply it to the affected area for immediate effect.

Congenital residual toxins are formed during fetal development, categorized into inherited (Bing Shou) and acquired/infected (Ran Shou) types. Cases without skin protection and with reddened bodies are difficult to cure; if red spots appear on the skin followed by ulceration, acquired infection can still be cured, but congenital inheritance of toxin is difficult to treat.
[Note] This condition involves congenital residual toxins in the placenta, divided into Bing Shou (inherited from parents) and Ran Shou (acquired through transmission). In cases of Bing Shou, the parents suffered from Yang Mei Chuang (Syphilis/Kapok Sores) before conception; after birth, the infant's entire body is red and lacks skin, with toxins attacking the nine orifices, leading to ulceration and maceration. This condition is difficult to cure, with almost no survivors. In cases of Ran Shou, conception occurred first, and the parents contracted Yang Mei Chuang (Syphilis/Kapok Sores) later; the toxic qi was transmitted to the fetus. After birth, the infant presents with pitted depressions on the head, red spots appearing on the skin first, followed by ulcerative patches. Severe cases involve toxins attacking the corners of the mouth, eye sockets, ears, nose, anterior yin, and anus, causing severe ulceration. Initially, use San Ren Huang (Human Midden Yellow) finely ground, 3-5 fen, mixed with a thick decoction of Tu Fu Ling (Smilax Glabra Rhizome), taken two to three times daily. Apply Tai Yi Zi Jin Ding (Taiyi Purple Gold Plaster) moistened with water to swollen areas. For ulcerated areas, use Huang Bo (Phellodendri Cortex) honey-fried and ground into powder to sprinkle; if dry, mix with Sesame Oil (Xiang You) for application. If the medication proves effective, subsequently administer Er Huang San (Two-Yellow Powder); four out of ten patients may survive. If the toxin spreads throughout the body, causing incessant crying day and night and refusal to feed, it indicates extreme toxicity and weak Qi, making rescue ultimately impossible.
Er Huang San (Two-Yellow Powder)
Hu Huang Lian (Coptidis Rhizoma variant/Hulian), Shan Ci Gu (Fritillaria Cirrhosae Bulbus) (each 2 qian), Gan Cao (Licorice Root, raw, 1.5 qian), Niu Huang (Calculus Bovis) (0.7 fen)
Grind all ingredients into a fine powder. Take 3 fen per dose, mixed with honey water.
[Prescription Verse] Er Huang San treats residual toxins, combining Hu Lian, Gan Cao, and Niu Huang; Shan Ci Gu is ground into fine powder, take 3 fen per dose with honey water.
