下结喉上。治舌下肿难言，舌纵涎出，口禁，舌根急缩，下食难。刺疟论云∶舌下两脉者，廉泉也。
刺禁论云∶刺舌下中脉太过，血不止为喑。刺节真邪论云∶取廉泉穴，血变而止。以明宜出血禁用针。
或问取廉泉穴二说不同，一说取颔下结喉上，一说取舌下两脉，何者为当？答曰∶舌本者，乃舌根蒂
也。若取舌下两脉，是取舌稍也，舌标也，此法误也。当取颔下者为当，此舌根也。况足阳明
之脉，根于厉兑，结于廉泉，颔下乃足阳明之所行也。若取舌下两脉，非足阳明经也。戊与癸合，廉

颔下结喉上者为准矣。胀论曰∶廉泉、玉英者，津液之道路也。张戴人治南 朱老翁，年六十余岁，
身热数日不已，舌根肿起，和舌尖亦肿，肿至满口，比原舌大三倍。一外科以燔针刺其舌两旁下廉泉
穴，病势转凶，将至颠 。戴人曰∶血实者宜决之，以 针磨令锋极尖，轻砭之，日砭八九次，出血
约一二盏，如此者三次，渐觉血少痛减肿消。夫舌者，心之外候也。心主血，故血出则愈。又诸痛痒

血泄毒，以救其急。惟舌下廉泉穴，此属肾经，虽宜出血，亦当禁针，慎之。
舌根肿胀称为重舌，舌头肿胀且僵硬不柔和的称为木舌。若风寒之邪损伤心脾，会导致患者憎恶寒冷、高热，牙齿浮痛、舌头肿痛，适宜用金沸草散含漱，吐出一半，吞下一半。治疗舌头肿胀，可用黄药汤。或者将乱发烧成灰，用水调服。外用方面，可将锅底煤研细，用醋调和敷在舌头的上下方，脱落后再敷，如果能先刺破放血，然后再敷药，效果更佳。另一方法是用盐和井花水等量调和敷贴。硼砂研成细末，切生姜蘸取药物擦拭肿胀处，肿胀即可消退。蓖麻取油，蘸纸捻燃烧冒烟熏烤患处也可治愈。好胆矾研细后敷贴亦可。舌上肿胀坚硬并出血，可用海螵蛸、蒲黄各等分研细，用井花水调匀敷贴。
对于肿胀，可用马牙硝丸、牛黄散、玄参散、飞矾散、[虫]散、百草霜散。（注：原文此处可能有脱字或通假，依原文列出）
仅用一味真蒲黄末撒布患处。又法用皂角刺少许、朴硝少许，研匀，先用手蘸水擦拭口腔内及舌头上下，然后将药粉撒布，涎液自然消除。又法用五灵脂一两，去除砂石研末，用一大碗米醋煎煮，慢慢含漱。又法选用不蛀的皂角四五挺，去掉皮和弦，炙干，加少许荆芥穗研成细末，用米醋调涂肿胀处。又以蛇蜕烧成灰，研至极细，取少量敷贴。乌犀膏、牛黄散、黄药汤也可使用。也可以用铍刀刺破出血，病即痊愈。《三因方》说：凡是舌头肿胀，下面一定有噤虫，形状像蝼蛄或卧蚕，有头尾，头部白色，可以用烧红的铁器烙烫其头部，虫子即消。如果不急治，能致人死亡。李东垣说：廉泉穴，又名舌本，位于下巴下、结喉之上。《刺疟论》说：舌下的两条脉络，就是廉泉。《刺禁论》说：针刺舌下如果伤中血脉导致出血不止，会导致失音。《刺节真邪论》说：取廉泉穴，直到血液颜色改变（由黑变红）就停止。这说明适宜放血但禁用深针。有人问取廉泉穴有两种说法不同，一说取下巴下结喉上，一说取舌下两脉，哪种正确？回答说：舌本，是舌根的蒂部。如果取舌下两脉，那是取舌尖，属于舌标，这种方法是错误的。应当取下巴下的位置才正确，这才是舌根。况且足阳明胃经的脉气，根源在厉兑穴，汇聚于廉泉穴，下巴下正是足阳明经所经过的地方。如果取舌下两脉，就不是足阳明经了。戊与癸相合，廉泉属足少阴肾经，主治涎水下溢。注解说：胃中热气上溢，廉泉开泄，所以涎水下溢，应当放血以泻胃中热。由此可知不是舌下两脉，以下巴下结喉上的位置为准。《胀论》说：廉泉、玉英，是津液运行的道路。张戴人治疗南部的朱老翁，六十多岁，身体发热数日不退，舌根肿起，连舌尖也肿，肿胀充满口腔，比原来的舌头大三倍。一位外科医生用燔针（烧红的针）刺其舌头两旁下方的廉泉穴，病情反而加重，几乎危及头顶生命。戴人说：血实者应当决破它，于是将针磨得极尖，轻轻砭刺，每天砭刺八九次，放出约一二盏血，这样进行了三次，逐渐觉得血量减少、疼痛减轻、肿胀消退。舌头是心的外候。心主血，所以出血就能痊愈。另外，各种痛痒疮疡，都归属于心火。燔针和艾火，都违背了这一道理。薛新甫说：凡是舌头肿胀严重，应当先刺破舌尖，或舌上，或旁边，放出血液以泄毒，来急救其危急。只有舌下的廉泉穴，此穴属肾经，虽然适宜放血，但也应当禁止用针深刺，务必谨慎。
The swelling of the root of the tongue is called *Chong She* (Double Tongue); swelling of the tongue that is stiff and not flexible is called *Mu She* (Wooden Tongue). If Wind-Cold pathogenic factors injure the Heart and Spleen, it causes aversion to cold with high fever, floating teeth with tongue swelling and pain. It is suitable to gargle with *Jin Fei Cao San* (Boiling Water Herb Powder), spitting out half and swallowing half. To treat tongue swelling, *Huang Yao Tang* (Yellow Herb Decoction) can be used. Alternatively, burnt hair powder mixed with water can be taken orally. Externally, soot from the bottom of a cauldron can be ground into fine powder, mixed with vinegar, and applied to the upper and lower surfaces of the tongue; reapply as needed. If bloodletting is performed first before application, the effect is even better. Another method uses equal parts of salt and well-water (*Jing Hua Shui*) mixed for topical application. Borax (*Peng Sha*) ground into fine powder, dipped on slices of fresh ginger, can be rubbed on the swollen area to reduce swelling. Castor oil (*Bi Ma Ren You*), applied to paper twists and smoked over the affected area, can also cure it. Fine powder of good-quality Chalcanthite (*Dan Fan*) can be applied topically. For tongue swelling that is hard and bleeding, cuttlebone (*Hai Piao Xiao*) and Polygonum multiflorum pollen (*Pu Huang*) in equal parts, ground fine and mixed with well-water, can be applied.
For swelling, *Ma Ya Xiao Wan* (Halloysite Pill), *Niu Huang San* (Calculus Bovis Powder), *Xuan Shen San* (Scrophulariae Radix Powder), *Fei Fan San* (Calcined Alum Powder), [Insect] Powder, and *Bai Cao Shuang San* (Burnt Grass Ash Powder) are used.
Using only pure *Pu Huang* (Polygoni Typhonii Pollen) powder sprinkled on the lesion is effective. Another method involves grinding a small amount of Gleditsia sinensis spine (*Zao Jiao Ci*) and Mirabilite (*Pu Xiao*) evenly; first wipe the inside of the mouth and tongue with wet hands, then sprinkle the powder, which will cause saliva to dissipate naturally. Another method uses five liang of Trogopterus dung (*Wu Ling Zhi*), free of sand and ground into powder, decocted in a large bowl of rice vinegar, and held in the mouth for gargling. Another method selects four or five unrotten stalks of Gleditsia sinensis fruit (*Zao Jiao*), removing the peel and strings, drying them by roasting, mixing with a small amount of Schizonepeta spike (*Jing Jie Sui*) ground into fine powder, and applying with rice vinegar to the swollen area. Burnt snake skin (*She Tui*), ground extremely fine, can be applied sparingly. *Wu Xi Gao* (Black Rhinoceros Horn Ointment), *Niu Huang San*, and *Huang Yao Tang* are also applicable. One may also use a lancet (*Pi Dao*) to prick and bleed the area for healing. The *San Yin Fang* states: Whenever there is tongue swelling, there must be "Jin Chong" (Lockjaw Worms) underneath, resembling mole crickets or silkworms, with heads and tails; the head is white. Burning iron can be used to cauterize the head of the worm, causing it to disappear. If not treated urgently, it can be fatal. Li Dongyuan stated: The *Lian Quan* acupoint, also known as *She Ben* (Root of the Tongue), is located below the chin and above the laryngeal prominence. The *Ci Mie Lun* states: The two vessels under the tongue are *Lian Quan*. The *Ci Jin Lun* warns: If needling the sublingual vessels is too deep and causes continuous bleeding, aphonia results. The *Ci Jie Zhen Xie Lun* states: When selecting the *Lian Quan* acupoint, stop when the blood changes color. This indicates that bloodletting is appropriate but deep needle insertion is contraindicated. Some ask about the discrepancy regarding the location of *Lian Quan*: one view places it below the chin above the larynx, while another places it at the two vessels under the tongue. Which is correct? The answer is: *She Ben* refers to the root of the tongue. Taking the two vessels under the tongue is taking the tip of the tongue (*She Biao*), which is incorrect. One should take the location below the chin, which is the true root of the tongue. Furthermore, the Foot-Yangming Stomach Meridian originates at *Li Dui* and converges at *Lian Quan*; the area below the chin is where the Foot-Yangming meridian travels. The vessels under the tongue do not belong to the Foot-Yangming meridian. Wu combines with Gui; *Lian Quan* belongs to the Foot-Shaoyin Kidney Meridian and treats salivary overflow. The commentary explains: Heat in the stomach overflows upward, opening *Lian Quan*, causing salivary overflow; thus, bloodletting should be used to drain stomach heat. Therefore, it is not the vessels under the tongue, but the location below the chin above the larynx that is accurate. The *Zhang Lun* states: *Lian Quan* and *Yu Ying* are the pathways for body fluids. Zhang Dairen treated an old man named Zhu in the south, aged over sixty, who had persistent fever for several days. His tongue root swelled up, extending to the tip, filling his mouth, three times larger than normal. A surgeon used a red-hot needle (*Fan Zhen*) to prick the *Lian Quan* points below the sides of the tongue, worsening the condition to near-death. Dairen said: "When blood is excessive, it should be drained." He sharpened a needle, lightly pricked the area, performing this eight or nine times daily, draining about one to two cups of blood. After three such sessions, the bleeding decreased, pain subsided, and swelling reduced. The tongue is the external manifestation of the Heart. The Heart governs blood; therefore, bleeding leads to recovery. Moreover, all pain, itching, sores, and ulcers belong to Heart Fire. Red-hot needles and moxibustion violate this principle. Xue Xinpu stated: For severe tongue swelling, one should first prick the tongue tip, top, or sides to release blood and detoxify for emergency relief. However, for the *Lian Quan* point under the tongue, which belongs to the Kidney Meridian, although bloodletting is suitable, deep needle insertion is strictly contraindicated; caution is advised.
