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，肿甚麻痒木通，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
则毒瓦斯攻里，令人昏愦、恶心，即名走黄。治法俱按疔门，禁用灸法。

唇疽生于上下唇，寒热交争毒瓦斯深，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。

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。

反唇疔生于嘴唇内侧边缘，锁口疔生于嘴角部位。初起时形状像粟米一样坚硬肿胀，伴有麻木、瘙痒和疼痛，这是由脾胃和心经的火毒积聚而成。
【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向内部的位置，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如粟米，颜色紫暗，质地坚硬如铁，肿胀严重时感到麻木、瘙痒且感觉迟钝（木通），伴有寒热交替发作，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，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”（疔疮毒邪内陷的危重证候）。治疗方法都按照疔疮门的规范进行，禁止使用灸法。
唇疽生于上唇或下唇，伴有寒热交替争作，说明毒气深入，患处颜色紫暗坚硬，时常感到麻木和剧烈疼痛，这是由于脾胃积热所致。
【注】这种病症生于嘴唇，无论在上在下、在左在右，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，时常感到麻木疼痛，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退，必然需要溃破排脓，治疗方法就按照痈疽肿疡、溃疡门的规范进行。
茧唇是由脾胃积火结聚而成的。初起时像豆粒大小，逐渐长成蚕茧的形状，坚硬疼痛，妨碍饮食。初起及已形成但无全身症状的患者，用蟾酥饼贴敷，上面覆盖陀僧膏，日久会逐渐消退。如果有口渴症状的，适宜服用清凉甘露饮。如果面色红赤、口唇干燥裂开、大便秘结的，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（手心、脚心发热及心胸烦热），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；如果溃烂后像翻花一样，时常流出津血水的，属于逆证（预后不良）。如果失于调理治疗，日久会变成上消、中消、下消（消渴病的三种类型）的病症，属于凶险之证。
Fanlip Ding (Reverse Lip Carbuncle) arises on the inner edge of the lip, while Suokou Ding (Lock-Mouth Carbuncle) occurs at the corner of the mouth. Initially, it presents as a hard, swollen nodule resembling a millet seed, accompanied by numbness, itching, and pain. This is caused by Fire-Toxin accumulation in the Spleen-Stomach and Heart meridians.
[Note] Both conditions are caused by Fire-Toxin. Fanlip Ding grows on the lip margin towards the inside; the upper lip belongs to the Spleen meridian, and the lower lip belongs to the Stomach meridian. Suokou Ding grows at the corner of the mouth and is governed by the Heart and Spleen meridians. At the onset, both present as small, hard nodules like millet seeds, with a purple color and hardness akin to iron. When swelling is severe, there is numbness, itching, and insensibility ("mutong"), accompanied by alternating chills and fever, mental restlessness, and nausea. In severe cases of Fanlip Ding, the lip may evert outward; in severe cases of Suokou Ding, the mouth may become unable to open. These are rapid-progressing conditions requiring immediate treatment. Delay allows the Toxin to invade the interior, leading to coma and nausea, a condition known as "Zouhuang" (Carbuncle Poison Spreading). Treatment follows the protocols for Ding diseases in the Ding section. Moxibustion is strictly prohibited.
Chuju (Lip Abscess) arises on the upper or lower lip, accompanied by alternating chills and fever, indicating deep-seated toxin. The lesion is purple, hard, and often feels numb and severely painful. Its cause is accumulated Heat in the Spleen and Stomach.
[Note] This condition occurs on the lips, regardless of position (upper/lower, left/right), and is caused by accumulated Heat in the Spleen and Stomach. The lesion is purple with a head, ranging in size from a date to a plum. It is swollen and hard as iron, with frequent sensations of numbness and pain. Severe cases involve alternating chills and fever. Initially, Shen Shou Wei Sheng Tang should be administered orally; for patients with excess constitution, Shuang Jie Gui Jin Wan is indicated. Topically, Li Gong Ding can be applied to resolve the swelling. If the lesion does not subside after several days, it must suppurate, and treatment should follow the protocols for Yong Ju (Abscesses and Ulcers) sections.
Jianchun (Silkworm Cocoon Lip) is formed by the aggregation of accumulated Fire in the Spleen and Stomach. It begins as a bean-sized nodule and gradually enlarges into a shape resembling a silkworm cocoon. It is hard and painful, interfering with eating. For early-stage cases or those that have formed without systemic symptoms, Chansu Bing (Toad Venom Cake) should be applied topically, covered with Tuoseng Gao (Monk's Plaster). With prolonged use, it will gradually subside. If thirst is present, Qingliang Ganlu Yin is appropriate. If the face is red, lips are dry and cracked, and constipation exists, this indicates an Excess of Qi pattern, and Liang Ge San is indicated. If symptoms are milder during the day and heavier at night, accompanied by five-palm heat (heat sensation in palms, soles, and chest), malar flush, and a deficient, rapid, and forceless pulse, Jiaban Bawei Wan is indicated to nourish Kidney Water and Yin. If the ulcer erupts with a fungating appearance ("fanhua") and discharges blood and fluid, it is considered a Ni syndrome (adverse prognosis). Neglect in regulation and treatment may lead to Shang Xiao, Zhong Xiao, and Xia Xiao (the three types of Xiao Ke/Wasting-Thirst disease), which indicates a ominous prognosis.
