木舌者，舌忽肿胀，转掉不仁。舌者心之苗，心者舌之本，因心经热毒而发，或因脏腑
壅热，心脾积热，其气上冲而发。甚则塞满口中，硬如山甲，若不急治，则致害人。更不可
用手去按，按则恐损舌根，每长致语言不清楚。如至啼叫无声，面色频变，而惊疼者不治。
治法以小刀点紫黑处，或刺舌下金津玉液二穴，破出血痰，以冰硼散吹之；内服荆防败毒散
，煎药内务多加山栀，乃泻火之要品也。
舌衄者，舌上出血，如线不止，是心胃火邪炽甚，逼血妄行，以六味地黄汤加槐花主之
，或黄连解毒汤、犀角地黄汤亦可；外用槐花炒研细干掺。
舌疳者，由心脾毒火所致。盖舌本属心，舌边属脾，因心绪烦扰则生火，思虑伤脾则气
郁，郁甚而成斯疾，其证最恶。初如豆，后如菌，头大蒂小，又名舌菌，疼痛红烂无皮，朝
轻暮重，急用北庭丹点之，自然缩小而愈。若失于调治，以致 肿，突如泛莲，或状如鸡冠
，舌本短缩，不能伸舒言语，时漏臭涎，再因怒气上冲，忽然崩裂，血出不止，久久烂延牙
龈，即名牙岩。甚则颔肿结核，坚硬时痛，皮色如常，顶 一点，色黯不红，破后时流臭水
，腐如 绵，其证虽破，坚硬仍前不退，此为绵溃，甚至透舌穿腮，汤水漏出，是以又名翻
花岩也。因舌难转掉，饮食妨碍，故每食不能充足，致令胃中空虚，而怯证悉添，日渐衰惫
。初起肿赤，宜用导赤散加黄连；虚者，归脾汤；便溏者，归芍异功汤。然此证治法虽多，
百无一生；纵施药饵，不过苟延岁月而已。
舌疔，舌上生紫泡，其形如豆，坚硬寒热，疼痛应心而起，亦心脾之火毒也。宜用蟾酥
丸含放舌下，随化随咽，以解内毒；甚者刺之，服犀角地黄汤。
木舌，是指舌头突然肿胀，转动不灵活且感觉麻木。舌是心的外候（心之苗窍），心是舌的根本，此病多因心经热毒引发，或因脏腑积热、心脾蕴热，热气上冲所致。严重时舌头会塞满口腔，坚硬如穿山甲鳞片，若不及时治疗，会导致死亡。更不可用手去按压，按压可能损伤舌根，往往导致语言不清。如果发展到啼哭无声、面色频繁变化并伴有惊厥疼痛的，属于不治之症。治疗方法是用小刀刺破紫黑色的部位，或者针刺舌下的金津穴和玉液穴，放出瘀血和痰浊，然后吹入冰硼散；内服荆防败毒散，煎药时务必多加栀子，因为栀子是泻火的要药。
舌衄，是指舌面上出血，像线一样流个不停，这是心胃火邪炽盛，逼迫血液妄行所致。以六味地黄汤加槐花为主方治疗，或者使用黄连解毒汤、犀角地黄汤也可以；外用炒研细的干槐花粉末撒在患处。
舌疳，是由心脾毒火引起的。大概舌体属于心，舌边属于脾，因心情烦躁而生火，思虑过度伤脾导致气机郁结，郁结严重就形成这种疾病，其症状最为凶险。起初像豆粒大小，后来像菌类，头大蒂小，又名舌菌，疼痛、发红溃烂无皮，早晨轻晚上重，急需使用北庭丹点涂患处，自然能缩小而痊愈。如果延误调治，导致肿胀突出，状如泛开的莲花，或形状像鸡冠，舌体短缩，不能伸展说话，时常流出臭涎，再加上怒气上冲，突然崩裂，血流不止，长久腐烂蔓延至牙龈，这就名叫牙岩。严重时下巴肿胀出现结核，坚硬且时而疼痛，皮肤颜色正常，顶部有一点发暗不红，破溃后时常流出臭水，腐烂如棉絮，虽然溃破，但坚硬依旧不退，这称为绵溃，甚至穿透舌头穿过腮帮，汤水漏出，所以又名为翻花岩。因为舌头难以转动，饮食受阻，所以每次进食都不能吃饱，导致胃中空虚，各种虚弱证候全部出现，日渐衰弱疲惫。初起红肿时，宜用导赤散加黄连；体质虚弱的，用归脾汤；大便溏稀的，用归芍异功汤。然而此病治疗方法虽多，但百无一活；即使施用药物，也不过是勉强延续岁月罢了。
舌疔，是舌头上生出紫色水泡，形状像豆粒，坚硬，伴有寒热症状，疼痛放射至心脏区域，这也是心脾之火毒所致。适宜用蟾酥丸含在舌下，随着融化随吞咽，以解除体内毒素；病情严重的进行针刺，服用犀角地黄汤。
Mu She (Wooden Tongue) refers to the sudden swelling of the tongue, resulting in stiff movement and numbness. The tongue is the sprout of the Heart (external manifestation of the Heart), and the Heart is the root of the tongue. This condition arises from heat-toxin in the Heart meridian, or due to accumulated heat in the Zang-Fu organs, specifically heat accumulation in the Heart and Spleen, with Qi rushing upward. In severe cases, the tongue fills the mouth and becomes hard as pangolin scales. If not treated urgently, it can be fatal. One must not press it with hands, as this may damage the root of the tongue, often leading to unclear speech. If it progresses to silent crying, frequent changes in facial complexion, and convulsive pain, it is incurable. Treatment involves pricking the purple-black areas with a small knife, or needling the Jinjin (Metal Fluid) and Yuye (Jade Liquid) acupoints under the tongue to release blood and phlegm, followed by blowing Bingpeng San (Ice and Borax Powder) into the wound. Internally, Jingfang Baidu San (Atractylodes and Saposhnikovia Decoction for Expelling Toxins) is administered, with Gardeniae Fructus (Gardenia) added in large amounts during decoction, as it is a key herb for purging fire.
She Nu (Tongue Hemorrhage) refers to bleeding from the surface of the tongue that continues like a thread. This is caused by excessive fire-evil in the Heart and Stomach forcing blood to move recklessly. The primary formula is Liuwei Dihuang Tang (Six-Ingredient Rehmannia Pill) with Sophorae Flos (Sophora Flower). Alternatively, Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxins) or Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) may be used. Externally, roasted and finely powdered dry Sophorae Flos is applied.
She Gan (Tongue Ulcer) is caused by toxic fire in the Heart and Spleen. Generally, the body of the tongue belongs to the Heart, and the sides belong to the Spleen. Mental agitation generates fire, while overthinking injures the Spleen causing Qi stagnation; severe stagnation leads to this disease, which presents with the most malignant symptoms. Initially, it resembles a bean, later growing like a fungus, with a large head and small stalk, also known as She Jun (Tongue Fungus). It is painful, red, ulcerated, and lacks skin. Symptoms are lighter in the morning and heavier in the evening. Beiting Dan should be applied promptly to shrink the lesion and effect a cure. If treatment is delayed, swelling protrudes like an open lotus or resembles a rooster's comb. The tongue becomes short and retracted, unable to extend for speech, leaking foul saliva. Aggravated by anger rising upward, it may suddenly rupture with uncontrollable bleeding. Over time, rot spreads to the gums, named Ya Yan (Tooth Rock). In severe cases, submandibular swelling and nodules appear, hard and intermittently painful, with normal skin color but a dark, non-red apex. After rupture, foul fluid flows, and the tissue rots like cotton. Despite ulceration, hardness persists, termed Mian Kui (Cotton Ulcer). It may even penetrate through the tongue and cheek, causing fluids to leak, hence also called Fan Hua Yan (Turning Flower Rock). Due to the tongue's immobility and difficulty eating, food intake is insufficient, leading to an empty stomach, various deficiency syndromes, and gradual debilitation. In the initial stage of redness and swelling, Daochi San (Guide Out Red Powder) with Coptidis Rhizoma (Huanglian) is suitable. For deficiency, Guipi Tang (Restore the Spleen Decoction) is used. For loose stools, Guishao Yigong Tang (Angelica and Paeonia Yi Gong Decoction) is indicated. Although many treatments exist, survival rate is less than one in a hundred; even with medication, life is merely prolonged temporarily.
She Ding (Tongue Carbuncle) manifests as purple blisters on the tongue, bean-shaped, hard, accompanied by chills and fever, with pain radiating to the heart region. This is also due to fire-toxin in the Heart and Spleen. Chan Su Wan (Toad Venom Pill) should be held under the tongue to dissolve and swallow, resolving internal toxins. In severe cases, needling is performed, and Xijiao Dihuang Tang is administered.
