小儿舌下近舌根处，其肿形似舌，故名重舌，亦因心脾之热，而成此症。古法主内服清热饮（如黄连、生地、
木通、生甘草、连翘、莲子、淡竹叶为引），水煎时时灌入口中。外吹凉心散（如青黛、硼砂、黄柏、黄连、人中
白、风化硝、冰片）研极细末，掺入舌下有效。
〔真按〕重舌因心脾有热，然脾之大络出于舌下，有热则气血俱盛，重生一舌，此属上焦实热。内以黄连、
生甘草、淡竹叶、牛蒡子、灯芯煎服。外用黑枣一个，去核留肉，贯入青矾一钱，纸包煨热，去枣不用，但以青
矾二分调水，以笔涂数次即消。
小儿舌肿，但以梅花冰片点之，或用蓖麻油蘸纸作燃，烧烟熏之，随即消缩。
小儿舌中出血不止，但用乌贼骨、蒲黄各等分。为细末，敷舌上愈。
小儿舌头溃烂，饮食难进，先用吴茱萸研末，好醋调敷两脚心，对时一换。再用人中白、儿茶、青黛、硼
砂、薄荷、玄明
粉、马庇勃、冰片，共研极细，掺之立效。
小儿舌硬生衣，但用真犀牛黄、朱砂、元精石，共研细末，频涂舌尖即愈。
小儿舌生红泡，此证与咽喉不同，但用蛇床子一两，罐内烧烟，吸入喉中自消。
小儿牙龈初作臭气，次则齿牙黑，甚则龈肉烂而出血，名曰牙疳。此由肾热，其气直奔上焦，故以走马为
喻。古法主内服沆瀣丹（方见上），外敷如圣散（如人中白、铜绿、麝香，共为细末），先以蜡树叶浸米泔水洗
净后搽此药。
〔真按〕小儿多因热病之后，或痘疹之后，火毒流于胃经，致有此患，势甚危急，甚则落牙、穿腮、透鼻，
一二日即能致命，故名走马，言其骤也，此症有五不治∶（一）舌根烂不能食者不治；（二）黑腐如筋者不治；
（三）白色肉浮者为胃烂不治，（四）牙落穿腮、鼻臭不堪闻者不治，（五）山根上发红点者不治。
须趁其初起时，急用生大黄三钱，丁香十粒，绿豆三钱，共研末，热醋调敷两足心。再用 赤透绿矾、 人中
白、雄黄精、真麝香、顶上梅花冰片，共研极细末。先用银针挑刮去腐肉紫血，然后以药末敷之，吐出毒血，方
能愈也。
再此症如兼两腿形如云片，或红或青，大小不一，痛而肿硬，步履艰难者，其腿上肿处，须用磁锋刺破出血，
随之以牛肉片贴之，日换数次，甚有效验。
The area under the tongue of a child, near the root of the tongue, swells in a shape resembling the tongue itself; hence it is named *Chong She* (Double Tongue, a swelling under the tongue resembling a second tongue). This condition also arises from heat in the Heart and Spleen. Ancient methods primarily advocated internal administration of *Qing Re Yin* (Heat-Clearing Decoction, composed of Huanglian, Shengdi, Mutong, Sheng Gancao, Lianqiao, Lianzi, and Dan Zhuye as guides), decocted in water and administered frequently into the mouth. Externally, *Liang Xin San* (Cool-the-Heart Powder, composed of Qingdai, Pengsha, Huangbai, Huanglian, Renzhongbai, Fenghua Xiao, and Bingpian) was ground into an extremely fine powder and applied to the sublingual area, which proved effective.
[True's Commentary] *Chong She* results from heat in the Heart and Spleen. However, the great collateral of the Spleen emerges from under the tongue; when heat is present, both Qi and Blood become abundant, causing a "second tongue" to regenerate. This belongs to excess heat in the Upper Jiao. Internally, one may decoct Huanglian, Sheng Gancao, Dan Zhuye, Niubangzi, and Dengxincao for ingestion. Externally, take one black date, remove the pit leaving only the flesh, insert one qian of Qingfan into the flesh, wrap it in paper, and roast until hot. Discard the date flesh; use only two fen of Qingfan mixed with water, applying it several times with a brush until it subsides.
For a child with a swollen tongue, simply apply Meihua Bingpian (Plum-blossom Borneol) or dip paper in Castor Oil (Ricini Oleum), ignite it, and fumigate with the smoke, after which the swelling will immediately subside.
If a child suffers from continuous bleeding from the middle of the tongue, mix equal parts of Octopus Bone (Haima Gu / Sepiae Endoconcha) and Pollen Typhae (Puhuang), grind them into a fine powder, and apply it to the tongue to cure.
For a child with ulcerated tongue making eating difficult, first grind Evodiae Fructus (Wuzhuyu) into powder, mix with good vinegar, and apply to the soles of both feet, changing it after one shichen (two hours). Then, mix Renzhongbai, Ercha, Qingdai, Pengsha, Bohe, Xuanmingfen, Maibo (Ma Bo), and Bingpian into an extremely fine powder, and sprinkle it on the lesion for immediate effect.
For a child with a stiff tongue covered by a white membrane (*She Sheng Yi*), use real Rhinoceros Horn (Xiniu Huang), Cinnabar (Zhusha), and Yuanjingshi, grind them into a fine powder, and frequently apply to the tip of the tongue to heal.
For red blisters appearing on a child's tongue, this condition differs from throat diseases. Use one liang of Cnidii Fructus (Shechuangzi), burn it in a jar, and have the child inhale the smoke into the throat, which will naturally dissipate.
When a child's gums initially emit a foul odor, followed by blackening of the teeth, and eventually rotting of the gum tissue with bleeding, it is named *Ya Gan* (Gum Gangrene). This is caused by Kidney heat rushing directly to the Upper Jiao, hence metaphorically referred to as "Running Horse" due to its rapid progression. Ancient methods primarily advocated internal administration of *Hangxie Dan* (see formula above) and external application of *Rusheng San* (Like-Saint Powder, composed of Renzhongbai, Tonglv, and Shexiang ground into fine powder). First, wash the area clean with rice water infused with Wax Leaf (Laye), then apply this medicine.
[True's Commentary] Children often suffer from this after febrile diseases or smallpox/rubella, where fire-toxins flow into the Stomach meridian, causing this affliction. The condition is critical; severely, it leads to tooth loss, cheek perforation, and nasal penetration, potentially fatal within one or two days. Hence it is called "Running Horse," indicating its swiftness. There are five untreatable signs: (1) Ulceration at the tongue root preventing eating; (2) Blackish decay resembling sinews; (3) Floating white flesh indicating stomach rot; (4) Tooth loss, cheek perforation, and unbearable nasal odor; (5) Red spots appearing on the Shan Gen (root of the nose). One must act quickly at the onset: use three qian of raw Dahuang, ten Dingxiang, and three qian of Lüdou, grind into powder, and apply with hot vinegar to the soles of both feet. Then, prepare a mixture of greenish-green Lvfan, Renzhongbai, Xionghuangjing, real Shexiang, and top-grade Meihua Bingpian, grinding them into an extremely fine powder. First, use a silver needle to puncture and scrape away necrotic tissue and purple blood, then apply the powder. Only after toxic blood is expelled can the patient be cured.
Furthermore, if this condition is accompanied by leg swellings resembling cloud patterns, varying in color (red or blue), size, pain, hardness, and difficulty walking, the swollen areas on the legs must be pricked with a magnetic edge to bleed, followed by applying slices of beef, changed several times daily, which yields significant efficacy.
