【总论】凡是肝脏有热，口中就会发酸。心脏有热，口中就会发苦。脾脏有热，口中就会发甜。肺脏有热，口中就会发辛（辣味）。肾脏有热，口中就会发咸。胃中有热，口中就会发淡。此外还有口臭的症状。
【口疮】将黄柏（炒制）、蒲黄、青黛、人中白（各取等量）研成细末，外敷患处。用陈年的白螺蛳壳（烧制成炭但保留药性），加入儿茶、冰片少许，共同研磨成极细的粉末，吹入患处一两次即可见效。如果因疼痛无法进食，可用五倍子（研成细末）撒在患处，之后便可进食。如果是口疮导致饮食难进，服用清热药物无效的情况，这是中焦脾胃虚弱，相火（寄居于肝肾的命门之火）上冲没有制约所致。必须服用理中汤（人参、白术、甘草、黑姜）来补益脾胃之虚，干姜可以散除火热之标症；病情严重的可加附子，或者口中含服官桂才能痊愈。或者使用黄连、干姜（各取等量）研细后搽涂患处，流涎后即可痊愈。捣取生姜的自然汁漱口数次，流出涎液即见效。将二十文铜钱烧红，投入酒中服用，立即见效。
【口疳疮】取红枣十枚（烧制成炭但保留药性），加入二分冰片研细，吹入患处即见效。
【三焦实热口舌生疮】黄芩（春季四两，夏季六两，秋季五两），黄连（春季四两，夏季五两，秋冬三两），大黄（春季三两，夏季一两，秋季二两，冬季五两）。各自炒制后研成细末，用蜂蜜制成丸剂，大小如梧桐子大。每次服用五七十丸，饭后用温水送服。这就是三黄丸。（药末也可用麻油调匀，涂抹各种热毒疮疡，效果极佳。）用吴茱萸研成细末，醋调后涂于足心过夜，引火下行即可痊愈。凡是口疮，无论新旧，夜间睡觉时用手将自己的睾丸拉紧，左右交替揉搓三五十次。只要在夜间醒来时进行即可。因饮酒引起的口疮一夜即可痊愈，久病者三五夜即可见效。
【口破】滑石（一钱），辰砂（三钱），冰片（二分），研成细末撒在患处即见效。（忌用水漱口，此方也治疗鹅口疮。）如果是破损溃烂者，用象牙或象皮刮成细末敷贴患处。
【口烂】生明矾（研磨至极细），敷贴患处立竿见影。或者含在口中良久，用水漱洗后再含。久烂不愈者，用人中白、真铜绿、杏仁（各取等量），加入少许冰片，共同研成细末敷于患处，同时治疗小儿走马牙疳。
【口唇肿痛】疼痛难以忍受，这是胃中风热所致。用瓷器的锋刃刺破患处放出紫黑色的血，然后用古铜钱磨猪油搽涂患处，肿胀即可消退。大黄生研细末，用猪胆汁调匀涂擦即见效。
【口唇燥裂】青皮烧成灰，用猪油调匀涂擦有效。橄榄泡汤饮用，核中的仁研烂敷于干燥处，或者用胭脂敷贴，都立竿见影。燥裂出血者，用白梅花瓣贴于患处，立即见效。以上这些方子，治疗唇疮也是通用的。
【口臭】香薷煎煮浓汤，稍微含在口中。此方也治疗口唇出血。连翘研成细末泡汤当茶饮用，多服几次即见效。儿茶（四两），桂花、硼砂、薄荷（各五钱），各自研细。用甘草三两熬成膏，加入药末制成丸剂，含在口中慢慢化开。白僵蚕（挑选直挺的，在新瓦上焙干并切断丝络），研成细末，用少许敷在患处，吐出涎液即痊愈。
【木舌】舌头肿大充满口腔，肿胀坚硬，语言不利。或者舌头胀大伸出嘴外，这是因为心火妄动，热气结聚于舌部，如果不紧急治疗就会致死。白矾、百草霜各取等量研成细末，用糟茄子的自然汁调服。如果没有茄子，就用白酒调服。不能服药者，用真蒲黄（研细调稀），频繁刷涂舌面，肿胀自然会消退。或者用针砭刺出血，稍后退肿后，急用通草、薄荷、黄连、牛蒡子（各一钱），甘草（五分），灯心草（二十根），水煎，饭后服用。忌食煎炒食物半个月，不再复发。（如果使用针刺，舌下不可乱刺。）
【舌胀退场门者】蓖麻油涂在绵纸上，将纸做成捻子（三五个），点燃后立即吹灭，用烟熏患处。很久之后肿胀就会消退。舌头伸出寸许者，用一分梅花冰片研细敷在舌上，舌头即可缩回。都是奇特的验方。
【重舌】舌尖重叠增厚称为重舌。牙皂角（无虫蛀的四五挺，去皮核炙烤至焦），荆芥穗（一钱），共同研成细末，用米醋调匀涂于患处，即可消退。

[General Discussion] Whenever the Liver has heat, the mouth tastes sour. When the Heart has heat, the mouth tastes bitter. When the Spleen has heat, the mouth tastes sweet. When the Lung has heat, the mouth tastes pungent (spicy). When the Kidney has heat, the mouth tastes salty. When the Stomach has heat, the mouth tastes bland. Additionally, there is the symptom of halitosis (bad breath).
[Mouth Ulcers] Use Huangbai (Phellodendri Cortex, stir-fried), Puhuang (Typhae Pollen), Qingdai (Indigo Naturalis), and Renzhongbai (Calcinus Humanis) in equal parts. Grind into fine powder and apply externally to the affected area. Take old white river snail shells (calcined to charcoal but retaining medicinal properties), add Ercha (Catechu) and Bingpian (Borneolum Syntheticum) in small amounts. Grind together into an extremely fine powder and insufflate into the affected area one or two times for immediate effect. If eating is impossible due to pain, use Wubeizi (Galla Chinensis, ground into fine powder) sprinkled on the lesion, after which eating can resume. In cases where mouth ulcers prevent food intake and cooling medicines fail to heal them, this indicates deficiency of Earth in the Middle Jiao with uncontrolled ascending Xianghuo (Ministerial Fire). One must administer Lizhong Tang (Replenish the Middle Decoction: Renshen, Baizhu, Gancao, Heijiang) to tonify the Spleen-Stomach deficiency; Ganjiang (Dried Ginger) disperses the superficial fire; for severe cases, Fuzi (Aconiti Lateralis Radix Praeparata) may be added, or Guigui (Cinnamomi Cortex) held in the mouth until healing occurs. Alternatively, use Huanglian (Coptidis Rhizoma) and Ganjiang (Dried Ginger) in equal parts, grind into fine powder, and apply to the lesion; salivation will cease and healing will follow. Crush fresh ginger to extract natural juice and rinse the mouth several times; salivation indicates efficacy. Burn twenty ancient copper coins until red-hot, drop them into wine, and drink; immediate effect is expected.
[Mouth Gangrene Ulcers] Take ten red dates (calcined to charcoal but retaining medicinal properties), add 2 fen of Bingpian (Borneolum Syntheticum), grind into fine powder, and insufflate into the affected area for immediate effect.
[Sanjiao Excess Heat Causing Mouth and Tongue Ulcers] Huangqin (Scutellariae Radix): 4 liang in Spring, 6 liang in Summer/Autumn, 5 liang in Winter. Huanglian (Coptidis Rhizoma): 4 liang in Spring, 5 liang in Summer, 3 liang in Autumn/Winter. Dahuang (Rhei Radix et Rhizoma): 3 liang in Spring, 1 liang in Summer, 2 liang in Autumn, 5 liang in Winter. Stir-fry each separately, grind into fine powder, and make pills with honey, sized like wu-tong seeds. Take 50-70 pills per dose, washed down with warm water after meals. This is Sanhuang Wan (Three Yellows Pill). (The powder can also be mixed with sesame oil and applied to all types of heat-toxins sores with great efficacy.) Use Wuzhuyu (Evodiae Fructus) ground into powder, mixed with vinegar, applied to the sole of the foot overnight to guide fire downward for cure. For any mouth ulcer, regardless of whether it is new or old, when going to bed at night, pull the testicles tightly by hand and rub left and right alternately 30-50 times. Perform this action whenever waking up at night. Those caused by alcohol consumption will heal in one night; chronic cases will show improvement in 3-5 nights.
[Mouth Lesions] Huashi (Talcum): 1 qian. Chensha (Cinnabar): 3 qian. Bingpian (Borneolum Syntheticum): 2 fen. Grind into powder and sprinkle on the lesion for immediate effect. (Avoid rinsing with water; this formula also treats E'kou chuang/Goose-mouth sore). If broken and ulcerated, use Ivory or Elephant Skin scraped into fine powder and applied to the site.
[Mouth Rot] Sheng Mingfan (Raw Alum), ground extremely fine, applied to the lesion for immediate effect. Or hold in the mouth for a long time, rinse with water, and hold again. For chronic non-healing rot, use Renzhongbai (Calcinus Humanis), Zhen Tonglv (Basic Copper Carbonate), Xingren (Armeniacae Semen Amarum) in equal parts, add a little Bingpian (Borneolum Syntheticum), grind into powder, and apply to the affected area. This also treats Xiao'er zouma yagan (Pediatric Gangrenous Gingivitis).
[Lip Swelling and Pain] Unbearable pain indicates Wind-Heat in the Stomach. Prick the area with a porcelain edge to release purple blood, then rub with pig fat ground using an ancient copper coin to reduce swelling. Dahuang (Rhei Radix et Rhizoma), raw and ground fine, mixed with pig bile for application, is effective.
[Lip Dryness and Cracking] Qingpi (Citri Reticulatae Pericarpium Viride) calcined to ash, mixed with pig fat for application, is effective. Drink olive infusion; crush the kernel inside the olive and apply to dry areas; or apply Zhīyān (Rouge); all provide immediate relief. For cracking with bleeding, apply Bai Meihua ban (White Plum Blossom petals) to the lesion for immediate effect. The above formulas are also used for treating lip sores.
[Halitosis] Decoct Xiangru (Elsholtziae Herba) into a strong decoction, hold slightly in the mouth. This also treats oral bleeding. Lianqiao (Forsythiae Fructus) ground into powder, infused in water as tea, taken frequently for effect. Ercha (Catechu): 4 liang. Guihua (Osmanthus Flower), Pengsha (Borax), Bohe (Menthae Haplocalycis Herba): 5 qian each. Grind all finely. Decoct Gancao (Glycyrrhizae Radix et Rhizoma) 3 liang into paste, mix with powders to make pills. Hold in mouth to dissolve slowly. Bai Jiangcan (Bombyx Batryticatus) (select straight ones, bake on new tile until dry and break silk threads), grind into fine powder, apply sparingly to the lesion; curing upon expulsion of saliva.
[Tongue Woodiness] Tongue swollen large filling the mouth, hard and swollen, speech impaired. Or tongue protrudes out of the mouth. This is due to reckless movement of Heart Fire, with heat knotting in the tongue. Urgent treatment is required, otherwise it leads to death. Baifan (Alumen) and Baicaoshuang (Soot from Chimney) in equal parts, ground fine. Mix with natural juice of fermented eggplant for oral administration. If eggplant is unavailable, use white wine. If unable to take medicine, use real Puhuang (Typhae Pollen), ground fine and thinned, frequently brush onto the tongue; swelling will recede. Alternatively, bleed using needle pricking. After slight reduction, urgently use Tongcao (Akebiae Caulis), Bohe (Menthae Haplocalycis Herba), Huanglian (Coptidis Rhizoma), Niubangzi (Arctii Fructus) [each 1 qian], Gancao (Glycyrrhizae Radix et Rhizoma) [0.5 qian], Dengxincao (Junci Medullia) [20 roots]. Decoct in water, take after meals. Avoid fried foods for half a month to prevent recurrence. (If using needles, do not prick randomly under the tongue.)
[Tongue Protrusion Receding into Mouth] Apply Sesame Oil (Ricini Oleum) to cotton paper, form into fuses (3-5 pieces), light them, blow out immediately, and smoke the affected area with the smoke. After a while, swelling subsides. For tongue protruding one cun, grind 1 qian of Meihua Bingpian (Borneolum Syntheticum) fine and apply to tongue to retract it. These are miraculous verified formulas.
[Double Tongue] Tongue tip overlapping and thickening is called Double Tongue. Ya Zaojiao (Gleditsiae Sinensis Spina) (non-borer, 4-5 spines, remove skin/seeds, roast until charred), Jingjisui (Schizonepetae Spica) [1 qian]. Grind into fine powder, mix with rice vinegar, apply to lesion for resolution.
[Tongue Numbness Loss of Taste] Huanglian (Coptidis Rhizoma) stir-fried with wine and ground fine. Make pills with rice paste. Take 5-7 fen per dose, 1 qian for severe cases, washed down with warm water after meals. Effective after several doses.
[Bleeding from Tongue Like Needle Holes] Decoct Xiangru (Elsholetziae Herba) and drink. Fa Hui (Hair Ash) 2 qian, mixed with rice vinegar, apply to bleeding site. Huaimi (Sophorae Flos) (stir-fried and ground into powder), sprinkle on site to stop bleeding. Subsequently, tonify with Renshen (Ginseng Radix), Gancao (Glycyrrhizae Radix et Rhizoma), Maidong (Ophiopogonis Tuber).
