治重舌木舌，肿满强硬，或疼不止，不能言语，宜用粗针线扎箸头上，刺患处，甚者数十刺为妙。只针舌尖及
舌两旁，舌中心及舌下切不可针，犯之令出血不止。其刺出之血，以红色者毒轻，紫色者为重，黑色者
最危。仍以蒲黄研末，擦舌上即消。舌或胀大肿硬，实时气绝，名为 舌（ ，衫，入声。）用皂矾不拘多少，
新瓦上以火 ，变红色为度，放地上候冷，研细搽舌上立愈。重舌木舌皆效。（ ，蔽根之饰，谓如 之蔽大相
上也）
舌肿满不能出声，以梅花冰片研烂敷之；或以食盐、百草霜共为末，井水调敷即效。
绊舌者，舌根下有筋一条，绊其舌尖，令舌短缩不能吮乳。细视之，明见舌根之下有筋如线，牵绊其舌。用
针轻轻挑断之，挑时但挑此筋，不可误伤舌根，为祸不小。曾见愚妇以刀割断之，误伤舌根，流血不止而死。
舌断能重生。用活蟹一只，炙干为末，敷之。此方至神至验。
经曰∶天有列星，人有齿牙。又曰∶手阳明之脉，入下齿中；足阳明之脉，入上齿中。故知上牙属胃，下牙
属大肠，齿属肾。凡齿生迟者，肾气不足也。盖肾主骨，齿者，骨之余，肾不足则髓亏，不能充乎齿，所以齿
迟。宜地黄丸。
上下牙床肿者，此手足阳明实热也。凉膈散为君，加知母、石膏、升麻为佐，频频含咽。
重龈者，肾脏积热，附龈而肿痛也。以针刺去其血，用盐汤洗净，黄柏为末敷之，效。小儿有多食肥肉，齿
牙臭烂不可近者，名为鼻息。此胃膈实热也，内服沆瀣丹，外以荆沥和姜汁含嗽。
牙疳者，初作臭气，次则齿牙黑，甚则龈肉烂而出血，名为宣露。此由肾热，其气直奔上焦，故以走马为喻，
宜速治之。若上下唇破，鼻穿齿落者，名曰崩沙，气喘痰潮，饮食减小则不可治。内服沆瀣丹，外以如圣散敷之。
梦中切牙，风热也。由手足阳明二经积热生风，故令相击而有声也。必在梦中者，风
属阳，动则风行于阳，静则风归于里也。宣风散。
切牙一证，惟痘疹见此为危候，余则皆无大害。亦有因病战栗鼓颔而斗牙者，治其本证，则自止也。
牙齿落后不复生者，由于舌舔之故，其肉顽浓。用针刺去其血，以鼠骨散搽之，自生。
治疗重舌、木舌，表现为舌头肿胀满硬、僵硬强直，或者疼痛不止，导致无法说话。适宜用粗针线扎在筷子头上，刺患处，病情严重的，刺数十下为妙。只针刺舌尖及舌头的两旁，舌头的中心及舌下切不可针刺，否则会导致出血不止。刺出的血，如果是红色的说明毒邪轻浅，紫色的说明病情较重，黑色的最为危险。再用蒲黄研成粉末，涂抹在舌上即可消退。如果舌头胀大肿硬，突然气息断绝，称为“舌（音同‘衫’的入声）”。用皂矾不拘多少量，放在新瓦上用火煅烧，直到变成红色为止，放在地上冷却后，研成细末搽在舌上，立刻痊愈。对重舌和木舌都有效。（注：此处指舌体肿大如遮蔽根部之饰物，形容其肿大程度之大）。
舌头肿胀满硬不能出声，将梅花冰片研烂敷在舌上；或者用食盐、百草霜共同研成粉末，用井水调匀敷在舌上即见效。
绊舌症，是指舌根下有一条筋，牵绊住舌尖，使舌头短缩不能吮吸乳汁。仔细查看，能明显看到舌根下有像线一样的筋，牵拉着舌头。用针轻轻挑断这条筋，挑的时候只挑这条筋，不可误伤舌根，否则祸患不小。曾见过愚笨的妇人用刀割断它，误伤了舌根，流血不止而死。
舌头断裂能够重新生长。用一只活蟹，烤干后研成粉末，敷在断处。此方非常神奇灵验。
《内经》说：天上有排列的星辰，人有牙齿和门牙。又说：手阳明经脉，进入下齿中；足阳明经脉，进入上齿中。因此知道上牙属于胃，下牙属于大肠，牙齿归属于肾。凡是牙齿生长迟缓的，是肾气不足的表现。因为肾主骨，牙齿是骨的余气，肾气不足则骨髓亏虚，不能充养牙齿，所以牙齿生长迟缓。适宜服用地黄丸。
上下牙床肿胀的，这是手阳明和足阳明经实热所致。以凉膈散为主药，加入知母、石膏、升麻作为辅佐药，频频含漱吞咽。
重龈症，是肾脏积热，附着在牙龈上导致肿痛。用针刺破放出血液，用盐汤洗净，用黄柏研成的粉末敷在患处，有效。小儿有多食肥肉的习惯，导致牙齿口臭腐烂不堪忍受的，称为“鼻息”。这是胃膈有实热，内服沆瀣丹，外用荆沥调和姜汁含漱。
牙疳症，初起时有臭气，接着牙齿变黑，严重时牙龈肉腐烂出血，称为“宣露”。这是由于肾热，热气直奔上焦，所以用走马（喻病势迅猛）来比喻，应当迅速治疗。如果上下嘴唇破裂，鼻子穿孔牙齿脱落，称为“崩沙”，伴有气喘痰涌，饮食减少，这就不可治了。内服沆瀣丹，外用如圣散敷贴。
睡梦中磨牙，是风热所致。由于手阳明和足阳明二经积热生风，所以导致牙齿相击发出声音。必定发生在睡梦中的原因，是因为风属阳，活动时风气行于阳分，静止时风气归于里。可用宣风散治疗。
磨牙这一症状，只有在痘疹病中出现时为危重证候，其他情况都没有大害。也有因病而战栗鼓颚导致咬牙的，治疗其根本病症，就会自然停止。
Treatment for *Chongshe* (Heavy Tongue) and *Mushe* (Wooden Tongue), characterized by tongue swelling, fullness, stiffness, and rigidity, or unceasing pain preventing speech, is suitable to be treated by tying a coarse needle/thread to the tip of a chopstick, piercing the affected area. For severe cases, piercing dozens of times is optimal. Only pierce the tip of the tongue and both sides; the center and underside of the tongue must never be pierced, as doing so will cause uncontrollable bleeding. Blood that is red indicates mild toxicity; purple indicates severity; black indicates critical danger. Subsequently, apply powdered *Puhuang* (Cattail Pollen) to the tongue to resolve the swelling. If the tongue swells and hardens suddenly leading to cessation of breath, it is named *She Shan* (Tongue [sound: 'shan' entering tone]). Use an unspecified amount of *Zaofan* (Alum), roast it on a new tile over fire until it turns red, place it on the ground to cool, grind into fine powder, and apply to the tongue for immediate cure. This is effective for both Heavy Tongue and Wooden Tongue. (Note: Refers to the tongue swelling so much it resembles a decorative cover obscuring the root).
For tongue swelling and fullness preventing speech, crush *Meihua Bingpian* (Borneol from Plum Blossom) and apply; or mix *Shiyan* (Rock Salt) and *Baicaoshuang* (Soot from Hundred Herbs) into powder, dilute with well water, and apply for effect.
*Banshe* (Tied Tongue) refers to a tendon under the root of the tongue that tethers the tip, causing the tongue to retract and preventing suckling. Upon close inspection, a thread-like tendon can be seen under the tongue root pulling the tongue. Gently sever this tendon with a needle; ensure only this tendon is cut and do not accidentally injure the tongue root, as the consequences would be severe. I have seen foolish women use a knife to cut it, accidentally injuring the tongue root, leading to fatal hemorrhage.
A severed tongue can regenerate. Use one live crab, dry it by roasting, grind into powder, and apply. This prescription is extremely miraculous and effective.
The Classic states: "As heaven has arranged stars, humans have teeth." It also states: "The Hand-Yangming meridian enters the lower teeth; the Foot-Yangming meridian enters the upper teeth." Thus, we know the upper teeth belong to the Stomach, the lower teeth belong to the Large Intestine, and the teeth are governed by the Kidney. Delayed tooth eruption indicates insufficient Kidney Qi. Since the Kidney governs bones, and teeth are the surplus of bones, insufficient Kidney Qi leads to marrow deficiency, failing to nourish the teeth, hence delayed eruption. *Dihuang Wan* (Rehmannia Pill) is appropriate.
Swelling of the upper and lower gums indicates excess heat in the Hand-Yangming and Foot-Yangming meridians. Use *Liangge San* (Cool the Diaphragm Powder) as the principal formula, add *Zhimu* (Anemarrhenae Rhizoma), *Shigao* (Gypsum Fibrosum), and *Shengma* (Cimicifugae Rhizoma) as assistants, and frequently gargle and swallow.
*Chongyin* (Double Gum) is caused by accumulated heat in the Kidneys attaching to the gums, causing swelling and pain. Pierce with a needle to release blood, wash with salt water, and apply powdered *Huangbai* (Phellodendri Cortex); this is effective. Children who consume excessive fatty meat may develop foul-smelling, rotting teeth, known as *Bixi*. This is due to excess heat in the Stomach and Diaphragm. Internally administer *Hangxie Dan*, and externally gargle with *Jingli* (Schisandra Juice) mixed with ginger juice.
*Yagan* (Tooth Gangrene) begins with foul odor, followed by blackening of the teeth, and severely progresses to rotting gums and bleeding, named *Xuanlu*. This is due to Kidney heat rushing to the Upper Jiao, likened to a running horse (indicating rapid progression), requiring urgent treatment. If the upper and lower lips break, the nose perforates, and teeth fall out, it is named *Bengsha*. With panting, tidal phlegm, and reduced food intake, it becomes incurable. Internally administer *Hangxie Dan*, and externally apply *Rusheng San*.
Teeth grinding during sleep is caused by Wind-Heat. Accumulated heat in the Hand-Yangming and Foot-Yangming meridians generates wind, causing teeth to strike each other. It occurs specifically during sleep because Wind belongs to Yang; when active, wind moves in the Yang aspect; when still, wind returns inward. Use *Xuanfeng San* (Disperse Wind Powder).
Among cases of teeth grinding, only those appearing during smallpox/variolous diseases are critical; others pose no major harm. Some patients clench teeth due to tremors and chattering jaws from illness; treating the underlying condition will stop it naturally.
Teeth that do not regrow after falling out are due to constant licking by the tongue, causing the tissue to become thick and callous. Pierce to remove stagnant blood, apply *Shugu San* (Rat Bone Powder), and they will naturally regrow.
