凉膈散（见口部） 黄连解毒汤 蟾酥丸（见疔疮门）
经络 当门为齿。上属督脉。下属任脉。两傍为牙。上属足阳明胃经。下属手阳明大肠经。夫牙者骨之
标而属肾。牙之生如木之栽于土也。如肠胃素有湿热。上出于牙龈之间。适被风寒。或为饮冷所逼。则
湿热不得外发而作痛。乃阳明病。非少阴病也。是症以寒为标。故外用擦漱之药宜辛温。取其散寒开
郁。以热为本。故内服之药宜辛凉。取其散热清中。如连翘汤之类。再火胜则痛必牵扯腮颧。加石膏。风
胜则肿。加防风。气胜则长。加栀子。气郁则胀。亦加栀子。痰胜则木。加贝母。外以醋漱之。去其痰涎。泻其
风热。疳慝则黑。加使君子肉。虫蚀则蛀。加槟榔。外以五灵脂汤化漱之以杀其虫。再血虚则齿痒。肠胃
虚则齿露。过于劳则齿浮。肾虚则齿豁。惟精固则齿坚。又当随其症而用滋补也。
舌上长出硬结，质地强硬且疼痛的，属于痰气阻滞。可用衣针点破患处，涂抹冰硼散，并服用清热降火、消除痰浊的药物。
舌上生疮，形状像杨梅，体表没有恶寒发热症状，但内心烦躁的，称为重疳（注：原文“重 ”疑为“重疳”或类似重症口疮，此处依语境译为重症口疮/重疳）。忌用针刺，适宜用黄连解毒汤加桔梗、甘草治疗，外用兼吹药粉。
舌上生疮，形状像豆子，坚硬伴有寒热，疼痛放射至心脏部位的，是疔疮。适宜含服蟾酥丸于舌下，随化随咽，或者再服用三粒以解除体内毒素。病情严重的可以针刺，或者艾灸少冲穴。
弄舌是指舌头微微伸出立即收回。这属于心脾经气血亏损。适宜用温脾散进行补益。大病初愈后出现此症者难以医治。
舒舌是指舌头伸长，很久才能收回。这是由于心脾积热所致。适宜用泻黄散主治。
经络方面：正中间的牙齿称为齿，上部归属督脉，下部归属任脉；两侧的牙齿称为牙，上部归属足阳明胃经，下部归属手阳明大肠经。牙齿是骨骼的外在表现，归属于肾。牙齿的生长就像树木栽种在土壤中一样。如果肠胃素来有湿热，向上出于牙龈之间，恰好遇到风寒侵袭，或被冷饮逼迫，那么湿热就不能向外发散而引发疼痛，这是阳明病，而不是少阴病。这个病症以寒邪为标象，所以外用的擦拭漱口药物宜用辛温之品，取其散发寒邪、开通郁结的作用；以热邪为本源，所以内服的药物宜用辛凉之品，取其散热、清解中焦热邪的作用，如连翘汤之类的方剂。如果火邪旺盛，疼痛必定牵扯到腮帮和颧骨，需加石膏；风邪旺盛则肿胀，加防风；气机亢盛则牙齿生长异常，加栀子；气机郁滞则胀满，也加栀子；痰湿旺盛则牙齿变黑（注：原文“木”疑为“黑”或特定指征，结合下文“疳慝则黑”，此处暂按原文逻辑或常见医理理解为色泽改变），加贝母，外用醋漱口以去除痰涎，泻除风热；疳积虫蚀则牙齿发黑，加使君子肉；虫蛀则出现蛀洞，加槟榔，外用五灵脂汤化开漱口以杀灭寄生虫。如果血虚则牙齿瘙痒，肠胃虚弱则牙龈萎缩牙齿显露，过度劳累则牙齿松动浮起，肾虚则牙齿稀疏豁落。只有精气固摄得当，牙齿才会坚固。又应当根据具体症状使用滋补的方法治疗。
The emergence of a small tongue beneath the main tongue is called *Chong She* (Double Tongue). It is appropriate to apply *Bingpeng San* (Ice and Borax Powder) topically.
If a nodule forms on the tongue, characterized by stiffness and pain, it is attributed to Phlegm-Qi stagnation. The nodule should be pricked with a clothing needle, followed by topical application of *Bingpeng San* and oral administration of herbs that clear heat, reduce fire, and resolve phlegm.
If sores form on the tongue, resembling bayberries, without external symptoms of chills or fever but accompanied by internal irritability, it is referred to as severe mouth sore (likely *Zhong Gan*). Pricking with needles is contraindicated. It is appropriate to treat with *Huanglian Jiedu Tang* (Coptis Decoction for Resolving Toxicity) supplemented with *Jiegeng* (Platycodon Root) and *Gancao* (Licorice Root), combined with the topical insufflation of medicated powder.
If a sore forms on the tongue, shaped like a bean, hard, accompanied by chills and fever, and the pain radiates to the heart region, it is a *Ding Chuang* (Carbuncle/Furuncle). It is appropriate to hold *Chansu Wan* (Toad Venom Pill) under the tongue, swallowing it as it dissolves, or take three additional pills to resolve internal toxicity. In severe cases, acupuncture may be used, or moxibustion applied to the Shaocong acupoint (*Shaochong*, HT9).
*Nong She* (Playing Tongue) refers to the tongue protruding slightly and immediately retracting. This belongs to deficiency in the Heart and Spleen meridians. It is appropriate to tonify with *Wenpi San* (Warm the Spleen Powder). Cases occurring after major illnesses are difficult to treat.
*Shu She* (Extended Tongue) refers to the tongue extending outward and taking a long time to retract. This is caused by accumulated heat in the Heart and Spleen. It is primarily treated with *Xiehuang San* (Drain the Yellow Powder).
*Liangge San* (Cool the Diaphragm Powder) (see Mouth section); *Huanglian Jiedu Tang* (Coptis Decoction for Resolving Toxicity); *Chansu Wan* (Toad Venom Pill) (see Carbuncle section).
Regarding meridians: The front teeth are called *Chi*, belonging superiorly to the Du Meridian and inferiorly to the Ren Meridian. The side teeth are called *Ya*, belonging superiorly to the Foot-Yangming Stomach Meridian and inferiorly to the Hand-Yangming Large Intestine Meridian. Teeth are the exterior manifestation of bones and belong to the Kidney. The growth of teeth is like planting trees in soil. If damp-heat exists internally in the stomach and intestines and rises to the gums, and is simultaneously constrained by wind-cold or forced by cold drinks, the damp-heat cannot diffuse outward, resulting in pain. This is a Yangming disease, not a Shaoyin disease. Since cold is the manifest aspect (biao), external rinsing and wiping medications should be pungent and warm to disperse cold and open stagnation. Since heat is the root aspect (ben), internal medications should be pungent and cool to dissipate heat and clear the middle jiao, such as *Lianqiao Tang* (Forsythia Decoction). If fire pathogen is excessive, pain will radiate to the cheeks and zygomatic arches; add *Shigao* (Gypsum Fibrosum). If wind pathogen is excessive, swelling occurs; add *Fangfeng* (Saposhnikovia Root). If qi is excessive, abnormal growth occurs; add *Zhizi* (Gardenia Fruit). If qi stagnation causes distension, also add *Zhizi*. If phlegm is excessive, discoloration occurs; add *Beimu* (Fritillaria Bulb), rinse externally with vinegar to remove phlegm-saliva and drain wind-heat. If caries cause blackening, add *Shijunzi Rou* (Seed of Quisqualis); if worms cause cavities, add *Binglang* (Areca Seed), rinse externally with *Wulingzhi Tang* (Trogopterus Dung Decoction) to kill parasites. If blood deficiency causes tooth itching, stomach-intestine deficiency causes gum recession and exposed teeth, overwork causes loose teeth, and kidney deficiency causes sparse teeth. Only when essence is secure will teeth be firm. Treatment should further involve tonification according to specific symptoms.
