陈实功曰∶重舌，乃心火妄动发之，舌下又有一舌也。当以线针点刺患上，令出
恶血，内服黄连泻心汤，外用冰硼散搽之。（《正宗》）
冯鲁瞻曰∶重舌者，心脾有热也。盖心候舌而主血，然脾脉络于舌下，火土又
子母也，有热即与血气俱盛。其状附舌下，而近舌根，生形如舌而微短小，色异，亦
宜针刺。（《锦囊》）
窦汉卿曰∶重舌，乃舌下生一小舌，其舌鲜红，其外证颏下浮肿，有硬核。此心
经受热，毒瓦斯出于舌下。先用紫雪掺之，流出热涎，急服甘桔汤加姜、灯心煎服。（《全书》）
又曰∶莲花重舌，乃蕴热乘风而发，心火炎上之义。
又曰∶莲花舌，乃舌下生三小舌，其状如莲花之形。但舌乃心之苗，心火上炎，
或思虑太过，或火气所伤，或酒后当风取凉，以致风痰相搏而成。此候急用清凉解
毒汤加减服之，再吹。如肿不散，须用小刀针出紫血为妙。
又曰∶舌下生小舌，名曰重舌。盖舌乃心苗，心火上炎故生之。用小刀点紫黑
处，吹冰片散，服甘桔汤加山栀、连翘之属。
又曰∶咽喉有肿，复生重舌，此两经受病，俱有邪也，心邪发于舌下，胃邪出
于喉咙。盖因喉间之邪，触起于心经之邪，则其病俱发。外证头疼项强，身发潮热者，
是也。探痰法同前，再用紫雪、冰片散治之。
汪省之曰∶重舌，大小男女俱生。乃心火妄动，当以线针点刺患上。（《理例》）
骆潜庵曰∶脾之脉络系舌傍，肝之脉络系舌本，心之脉络系舌根，三经受胎毒
而上攻，舌下又像有一舌也，名曰重舌。宜延寿丹。（《推拿秘书》）
澄曰∶重舌、莲花重舌，有男妇心绪遏郁，忧思过度之人，每生此证。因循日
久，以致溃烂腐秽。舌头一烂，外壳虽存，其中如烂鱼肠相似，断不可用升炼药吹搽，
一用即血出如泉，穿腮腐龈，百不一生。澄见数证，俱因庸工妄治而亡，不可不慎。
Chen Shigong stated: Chong She (Double Tongue) is caused by the reckless movement of Heart Fire, manifesting as an additional tongue-like structure beneath the tongue. The affected area should be pricked with a thread needle to release foul blood. Internally, Huanglian Xiexin Tang (Coptis Decoction to Drain the Heart) should be administered; externally, Bingpeng San (Borneol and Borax Powder) should be applied. (*Waike Zhengzong*)
Feng Luzhan stated: Chong She results from Heat in the Heart and Spleen. Since the Heart corresponds to the tongue and governs Blood, and the Spleen's meridians connect to the underside of the tongue, with Heart (Fire) and Spleen (Earth) sharing a mother-son relationship, the presence of Heat causes both Qi and Blood to become excessive. The condition attaches to the underside of the tongue, near the root, resembling a tongue but slightly shorter, with a different color. Pricking with needles is also suitable. (*Yizong Jinjian - Jinnang Milu*)
Dou Hanqing stated: Chong She involves the growth of a small tongue beneath the main tongue, which appears bright red. External signs include swelling under the chin and hard nodules. This indicates Heat in the Heart Meridian, with toxic vapors emerging from under the tongue. First, apply Zixue San (Purple Snow Powder); after hot saliva flows out, urgently administer Ganjie Tang (Licorice and Platycodon Decoction) decocted with Shengjiang (Fresh Ginger) and Dengxincao (Juncus Effusus). (*Chuangyang Jingyan Quanshu*)
He further stated: Lianhua Chong She (Lotus Double Tongue) arises when accumulated Heat combines with Wind pathogen, reflecting the principle of Heart Fire flaring upward.
He further stated: Lianhua She (Lotus Tongue) involves the growth of three small tongues beneath the main tongue, shaped like a lotus flower. Since the tongue is the sprout of the Heart, Heart Fire flaming upward, excessive rumination, injury by Fire pathogen, or cooling off while exposed to wind after drinking alcohol can cause Wind and Phlegm to struggle against each other, forming this condition. It is urgent to take Qingliang Jiedu Tang (Cooling and Detoxifying Decoction) with modifications, followed by insufflation of powder medicines. If the swelling does not subside, it is essential to prick out purple-black blood with a small knife.
He further stated: The growth of a small tongue beneath the main tongue is named Chong She. Because the tongue is the sprout of the Heart, Heart Fire flaming upward causes its formation. Use a small knife to prick the purple-black areas, insufflate Bingpian San (Borneol Powder), and take Ganjie Tang (Licorice and Platycodon Decoction) added with Zhizi (Gardenia) and Lianqiao (Forsythia).
He further stated: Swelling in the throat accompanied by Chong She indicates disease in both the Heart and Stomach meridians, with pathogens present in both. Heart pathogen manifests under the tongue, while Stomach pathogen emerges in the throat. When the pathogen in the throat triggers the pathogen in the Heart meridian, both diseases erupt simultaneously. External symptoms include headache, stiff neck, and tidal fever. The method for inducing expectoration is the same as before; subsequently treat with Zixue San (Purple Snow Powder) and Bingpian San (Borneol Powder).
Wang Shengzhi stated: Chong She occurs in men, women, adults, and children alike. It is due to the reckless movement of Heart Fire; the affected area should be pricked with a thread needle. (*Yangyi Lili*)
Luo Qian'an stated: The Spleen's meridians tie to the sides of the tongue, the Liver's meridians tie to the root of the tongue, and the Heart's meridians tie to the base of the tongue. When the three meridians are attacked by fetal toxin moving upward, a second tongue-like appearance forms under the tongue, named Chong She. Yanshou Dan (Longevity Pill) is appropriate. (*Tuina Mishu*)
Gu Shicheng stated: Chong She and Lianhua Chong She often occur in men and women who are emotionally depressed and have suffered excessive worry and rumination. If neglected over time, it leads to ulceration and putrefaction. Once the tongue tip ulcerates, although the outer shell remains, the interior resembles rotting fish intestines. One must absolutely avoid using refined/mineral drugs for insufflation or application; doing so will cause blood to gush like a spring, leading to perforation of the cheeks and rotting of the gums, with almost no survivors. I have seen several cases where patients died due to the reckless treatment by incompetent practitioners. Caution is imperative.
