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。
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.
