一友姓郑，肝气素旺，易发恼怒，复好饮酒，嗜食煎炒，忽一日牙肉肿痛，流血不止。一医用犀角地黄汤不
止，改用三黄汤、清火解毒汤，其血愈甚。患此证旬日不止，仓皇无措，召余诊脉。余见其脉，六脉洪大，寸口
急数，有七至余。谓其病者曰∶此阳明胃积热证无疑，但火势已甚，恐不能直折，仍用前三黄汤合地黄汤，少加
炒黑肉桂从治，则其火必下降也。服二剂，其血立止。凡火证正治反增，必须从其性以治之，此乃先贤之秘方也。

手阳明大肠经的支脉进入牙齿。如果头面部受风邪侵袭，且阳明经脉虚弱，风邪挟带热邪乘虚侵入齿龈，与血液搏结，导致出血。（出自《诸病源候论》）
若阳明实热极盛，大便闭结不通，同时齿衄（牙龈出血）不止者，适宜使用调胃承气汤攻下泄热。若是肾水不足，口中无臭味，牙齿不疼痛，仅表现为牙齿松动不坚固，或轻微疼痛不甚严重，但牙缝时常大量出血者，这是肾阴不固，虚火偶尔扰动所致，只宜补肾，以六味地黄丸等方剂为主治。若是其阳气虚于下焦，导致虚火上炎者，适宜用八味丸（金匮肾气丸）等方剂主治。（出自张景岳《景岳全书》）
《短剧方》记载治疗饮酒醉后，牙齿涌出鲜血喷射而出，无法控制的方法。

一位姓郑的朋友，肝气素来旺盛，容易发怒，又好饮酒，嗜食煎炸炒制食物。忽然有一天牙肉肿痛，流血不止。一位医生用犀角地黄汤治疗无效，改用三黄汤、清火解毒汤，出血反而更严重。患病旬日不止，惊慌失措，召我诊治。我看他的脉象，六脉洪大，寸口脉急数，达到七至以上。我对他说：这无疑是阳明胃积热证，但火势已经非常猛烈，恐怕不能直接折损，仍用前三黄汤合地黄汤，少加炒黑肉桂从治（反佐），那么火势必然下降。服用两剂后，出血立即停止。凡是火证，正面治疗反而加重，必须顺从其本性来治疗，这是先贤的秘方。（出自《医约》）
进士董公，在王戌年考中进士时，牙龈流血不止，各种方法都无效。我教他用煮过的乌梅去掉复选肉（果肉），捣成大丸，含在患处，几丸后就痊愈了。（出自《程星海医案》）
The branch of the Hand-Yangming Large Intestine Meridian enters the teeth. If wind pathogen invades the head and face, and the Yangming meridian is deficient, wind carrying heat enters the gums through the deficiency, combats with blood, causing bleeding. (From *Zhu Bing Yuan Hou Lun*)
If Yangming excess-heat is severe, accompanied by constipation and unceasing dental epistaxis (gingival bleeding), it is appropriate to use Tiaowei Chengqi Tang (Regulate the Stomach Purge Decoction) to purge downward. If Kidney water is insufficient, with no foul odor in the mouth and no toothache, but only loose and unstable teeth or slight pain, yet frequent heavy bleeding from the gum spaces, this is due to insecure Kidney Yin and occasional movement of deficient fire; treatment should focus on strengthening the Kidney, primarily using Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill). If Yang Qi is deficient in the lower jiao leading to floating deficient fire, Bawei Wan (Eight-Ingredient Pill, i.e., Jin Gui Shen Qi Wan) should be used. (From Zhang Jingyue's *Jingyue Quanshu*)
*Duanju Fang* records a method for treating spurting blood from teeth after drunkenness that cannot be controlled.
Take small iron nails, burn them until red-hot, and place them directly over the bleeding hole; one application stops the flow ("xi" in the original text should be "duan", meaning cut off). The nail must be red-hot; if not red-hot, it cannot stop the bleeding. (From *Ishinpo*)
*Jingxin Fang* treats bleeding between teeth.
Take strong decoction of Mingcao (Herba Siegesbeckiae or similar local herb), do not add salt, hold in mouth at suitable temperature for rinsing, perform all day for good effect. (Ibid.)
Method for unceasing exudation of saliva and blood from the gums.
Raw Zhuru (Bamboo Shavings) two liang, boil with vinegar and hold in mouth. (From *Qianjin Fang*)
Another formula: Burn Fan Shi (Alumen) one liang, add three sheng of water, boil to obtain one sheng. Test on blood first, then hold in mouth. Do not use subsequently, as it will rot the tooth roots and cause tooth loss. (Ibid.)
Method for bleeding between teeth: Warm half a sheng of童子小便 (Child's Urine), take three he and hold in mouth; the bleeding will stop immediately. (Ibid.)
Bisheng San (Victory Powder), treats dental epistaxis.
Puhuang (Pollinis Typhae, slightly stir-fried) and Luo'er Qing (Shells of Concha Haliotidis, equal parts).
Grind into fine powder. Apply a small amount to the affected area, wait a moment, then rinse with warm salt water. (From *Jisheng Xufang*)
Bleeding from gum spaces: Rinse with salt soup. (From *Bencao Yan Yi*) (*Yi Shuo* states: *Su Wen* says salt conquers blood. *Bencao Gangmu* states: This is proof of salt benefiting teeth and moving blood.)
Treats bleeding from all teeth: Grind Gouqigen (Radix Lycii) into powder, decoct for rinsing, then swallow. Also treats hematemesis from above the diaphragm, excellent effect. (Cited from Sun Simiao in *Bencao Gangmu*). Another method: Burn Wubeizi (Galla Chinensis) to ash, rub on teeth. (From *Ruyi Fang*)
Bleeding from gum spaces like a gush or thin thread is named Chi Nu (Dental Epistaxis). Popular tradition uses silver hairpin tips heated red-hot to cauterize the bleeding hole to stop bleeding. Afterwards, administer Qingwei San (Clear the Stomach Powder) plus cooked Dahuang (Radix et Rhizoma Rhei), according to *Zhunsheng*, which has been frequently effective after passing two or three black stools. (From *Yixue Liuyao*) (Note: Qingwei San was originally Dongyuan's formula for toothache, composed of Shengdi Huang, Shengma, Danpi, Danggui, Huanglian.)
Qingwei San (Clear the Stomach Powder) treats heat in the Stomach meridian, swelling of teeth or gums, and unceasing bleeding.
Huangqin (Radix Scutellariae), Huanglian (Rhizoma Coptidis), Shengdi Huang (Radix Rehmanniae Preparata), Danpi (Cortex Moutan), Shengma (Rhizoma Cimicifugae), Shigao (Gypsum Fibrosum) (each one qian).
Add two zhong of water, decoct to eight fen, take after meals. (From *Waike Zhengzong*)
A friend surnamed Zheng had naturally vigorous Liver Qi, prone to anger, and enjoyed drinking alcohol and eating fried foods. Suddenly, his gingiva swelled and hurt, with unceasing bleeding. A doctor treated him with Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) without success, then switched to Sanhuang Tang (Three Yellows Decoction) and Qinghuo Jiedu Tang (Clear Heat and Detoxify Decoction), making the bleeding worse. After ten days of unceasing bleeding, he was panicked and summoned me. I observed his pulse: all six positions were surging and large, the Cun position was rapid and tense, exceeding seven beats per breath. I told him: This is undoubtedly accumulation of heat in the Yangming Stomach, but the fire is so intense that direct suppression may fail. Use the previous Sanhuang Tang combined with Dihuang Tang, adding a small amount of stir-fried black Rougui (Cortex Cinnamomi) for counter-treatment (reverse adjuvant), so the fire will descend. After two doses, the bleeding stopped immediately. For fire syndromes, direct treatment may exacerbate; one must treat according to its nature. This is the secret recipe of the sages. (From *Yiyue*)
Scholar Dong Gong, when he passed the imperial examination in the Wangxu year, suffered from unceasing gingival bleeding, to which all methods failed. I taught him to use boiled Wu Mei (Fructus Mume), removing the flesh, pounding it into large pills, and holding them in the affected area; after several pills, he was cured. (From *Cheng Xinghai Yian*)
