【方歌】反唇疔发唇里棱，锁口疔在嘴角生，粟米坚肿麻痒痛，
脾胃心经火毒成。
【注】此二证俱由火毒而成。反唇疔生于唇棱偏里，上唇属脾
，下唇属胃；锁口疔生于嘴角，系心、脾二经所属。二
证初起形如粟米，色紫坚硬如铁，肿甚麻痒木痛，寒热
交作，烦闷作呕。反唇甚则令唇外翻，锁口甚则口不能
开，俱属迅速之证，须当速治，迟则毒气攻里，令人昏
愦、恶心，即名走黄。治法俱按疔门，禁用灸法。
【方歌】唇疽生于上下唇，寒热交争毒气深，紫硬时觉木痛甚，
脾胃积热乃其因。
【注】此证生于唇，无论上下、左右，由脾、胃积热所致。色
紫有头，大者如李，小者如枣，肿硬如铁，时觉木痛，
甚则寒热交作。初宜服神授卫生汤，里实者服双解贵金
丸，外用离宫锭涂之即消。若过数日犹不消者，必欲溃
破，治法即按痈疽肿疡、溃疡门。
方剂：神授卫生汤、双解贵金丸、离宫锭（俱见肿疡门）
【方歌】茧唇脾胃积火成，初如豆粒渐茧形，痛硬溃若翻花逆，
久变三消定主凶。
【注】此证由脾、胃积火结聚而成。初起如豆粒，渐长若蚕茧
，坚硬疼痛，妨碍饮食。初起及已成无内证者，用蟾酥
饼贴之，陀僧膏盖之，日久渐消。或口渴者，宜服清凉
甘露饮。若面赤、口唇燥裂、便秘者，此属气实，宜服
凉膈散；若日轻夜重，五心烦热，两颧现红，脉虚数无
力者，宜服加减八味丸，以滋水养阴；若溃后如翻花，
时津血水者属逆。失于调治，久则变为上消、中消、下
消之证，属凶。

【方歌】反唇疔生于嘴唇内侧边缘，锁口疔生于嘴角部位。初起时形如粟米，坚硬肿胀，伴有麻木、瘙痒和疼痛，这是由于脾胃和心经的火毒积聚所致。
【注】这两种病症都是由火毒引起的。反唇疔生长在嘴唇棱边偏内侧的位置，上唇归属于脾经，下唇归属于胃经；锁口疔生长在嘴角，属于心和脾两经所主。这两种病初起时形状像粟米，颜色紫暗，质地坚硬如铁，肿胀严重，伴有麻木、瘙痒和木然疼痛，同时出现寒热交替发作，心烦闷乱并想呕吐。反唇疔严重时会导致嘴唇外翻，锁口疔严重时会导致嘴巴无法张开，两者都属于发展迅速的病症，必须迅速治疗，如果延误，毒气会攻入体内，导致人昏迷不醒、恶心，这就叫做“走黄”。治疗方法均按照疔疮门的规范进行，禁止使用灸法。
【方歌】唇疽生长在上下嘴唇，表现为寒热交争且毒气深重，患处色紫坚硬，时常感到剧烈的木痛，这是由于脾胃积热造成的。
【注】这种病症发生在嘴唇，无论上下左右，都是由脾胃积热引起的。患处颜色紫暗且有脓头，大的像李子，小的像枣子，肿胀坚硬如铁，时常感到木痛，严重时会出现寒热交替发作。初期适宜服用神授卫生汤，体质壮实者服用双解贵金丸，外用离宫锭涂抹即可消散。如果过了几天仍然没有消散，必然要溃破，此时的治疗方法就按照痈疽肿疡、溃疡门的规范进行。
方剂：神授卫生汤、双解贵金丸、离宫锭（均见肿疡门）
【方歌】茧唇由脾胃积火形成，初起时像豆粒，逐渐长成蚕茧的形状，疼痛坚硬，溃烂后若呈翻花状则为逆证，日久转变为三消症则定为主凶之兆。
【注】这种病症由脾胃积火结聚而成。初起时像豆粒，逐渐长大如同蚕茧，坚硬疼痛，妨碍饮食。初起及已成但未出现内证者，用蟾酥饼贴敷，再用陀僧膏覆盖，日久会逐渐消散。如果有口渴症状的，适宜服用清凉甘露饮。如果面色红赤、口唇干燥开裂、便秘的，这属于气实证，适宜服用凉膈散；如果白天轻晚上重，五心烦热，两颧发红，脉象虚数无力的，适宜服用加减八味丸，以滋补肾水、滋养阴液；如果溃烂后呈现翻花状，时常流出津血水的，属于逆证。如果失于调理治疗，日久会转变为上消、中消、下消的症状，属于凶险之证。

[Prescription Verse] Fanliping (Reverse Lip Ding) arises on the inner edge of the lips; Suokouding (Lock-Port Ding) appears at the corners of the mouth. Initially, it resembles a millet seed, with hardness, swelling, numbness, itching, and pain. These are caused by Fire-Toxin accumulation in the Spleen, Stomach, and Heart meridians.
[Annotation] Both conditions are caused by Fire-Toxin. Fanliping occurs on the inner side of the lip ridge; the upper lip belongs to the Spleen meridian, and the lower lip belongs to the Stomach meridian. Suokouding occurs at the mouth corner and is governed by the Heart and Spleen meridians. At the onset, both present like millet seeds, with purple coloration and hardness resembling iron. Severe swelling brings numbness, itching, and dull pain, accompanied by alternating chills and fever, mental restlessness, and nausea. In severe cases of Fanliping, the lip may evert; in severe cases of Suokouding, the mouth cannot open. Both are rapid-onset conditions requiring immediate treatment. Delay allows Toxin-Qi to attack the interior, causing coma and nausea, termed Zouhuang (Spreading Yellow). Treatment follows the protocols for Ding diseases in the Ding section. Moxibustion is strictly prohibited.
[Prescription Verse] Chuju (Lip Carbuncle) arises on the upper or lower lips, characterized by alternating chills and fever with deep-seated Toxin-Qi. The area is purple, hard, and experiences severe dull pain. This is due to Heat accumulation in the Spleen and Stomach.
[Annotation] This condition affects the lips, regardless of position, caused by Heat accumulation in the Spleen and Stomach. It presents with purple coloration and a head (pustule), ranging in size from a date to a plum. It is swollen and hard as iron, with intermittent dull pain. Severe cases involve alternating chills and fever. Initially, Shen Shou Wei Sheng Tang (Divine Grant Health Preservation Decoction) is appropriate. For patients with excess internal fullness, Shuang Jie Gui Jin Wan (Double Resolution Precious Gold Pill) is used. Externally, Li Gong Ding (Imperial Palace Ointment) applied topically can resolve the swelling. If it persists for several days without resolving, it will inevitably suppurate; treatment then follows the protocols for Ulcerative Sores and Ulcers in the respective sections.
Formulas: Shen Shou Wei Sheng Tang, Shuang Jie Gui Jin Wan, Li Gong Ding (all see Section on Ulcerative Sores)
[Prescription Verse] Jianchun (Silkworm Cocoon Lip) is formed by Fire accumulation in the Spleen and Stomach. It begins like a bean grain and gradually takes the shape of a silkworm cocoon. Hardness and pain interfere with eating. If it ulcerates into a "turning flower" appearance, it is an adverse sign. If it progresses over time to Sanxiao (Three Wasting-Thirst syndromes), it indicates a poor prognosis.
[Annotation] This condition results from the aggregation of Fire accumulation in the Spleen and Stomach. Initially, it resembles a bean grain, growing larger like a silkworm cocoon, becoming hard and painful, hindering diet. For early-stage cases or established cases without internal symptoms, Chansu Bing (Toad Venom Cake) is applied, covered with Tuoseng Gao (Monk's Plaster), which gradually resolves over time. For those with thirst, Qingliang Ganlu Yin (Cooling Sweet Dew Decoction) is suitable. For those with red face, dry/cracked lips, and constipation, this indicates Qi Excess; Liang Ge San (Cooling Diaphragm Powder) is appropriate. For those with symptoms lighter during the day and heavier at night, five-palm heat, malar flush, and a deficient-rapid weak pulse, Jiajian Bawei Wan (Modified Eight-Ingredient Pill) is used to nourish Kidney Water and Yin. If it ulcerates into a "turning flower" appearance with discharge of fluids and blood, it is an adverse sign. Neglect in regulation and treatment leads to Shangxiao, Zhongxiao, and Xiaxiao syndromes over time, indicating a ominous prognosis.
Formula: Qingliang Ganlu Yin
Composition: Maidong (Ophiopogonis Radix, heart removed), Zhimu (Anemarrhenae Rhizoma), Huangqin (Scutellariae Radix), Shihu (Dendrobii Caulis), Zhike (Aurantii Fructus, bran-fried), Pipaye (Loquat Leaf, hair removed, honey-fried), Yinchaihu (Cistanches Caulis - *Note: Text says Yin Chai Hu, usually Cistanches or Stellariae, here likely Cistanches or related cooling herb, WHO term often Cistanche or similar context dependent, but standard is Cistanches/Cistanche Herba or Stellariae Root depending on variant. Given context of clearing deficiency heat, likely Cistanches or similar. However, standard Pinyin/English mapping for 银柴胡 is Cistanches Caulis or Stellariae Radix. Let's use Cistanches Caulis (Yin Chai Hu)*), Xijiao (Rhinocerotis Cornu - *Note: Substitute with Buffalo Horn/Shuiniujiao in modern practice, but text says Xijiao*), Shengdi (Rehmanniae Radix Preparata), Yinchenshao (Artemisiae Scopariae Herba), Gancao (Glycyrrhizae Radix et Rhizoma, raw, each 1 qian).
