走马疳者，多因气虚受寒，郁热在内，或食甜酸盐腻之物，积滞日久，蕴热上冲，
齿焦黑烂，间出清血，血聚成脓，脓臭成虫，侵蚀口齿，甚有腮颊穿破，乳食难进，
气喘热作而危矣。治法宜内服清解，先去积热，外用温盐水净，吹以去涎拔热之药，切
不可纯以寒凉敛遏，以致郁热无从发泄，厥溃更深矣。以走马名之者，盖齿属肾，肾气
一虚，则虚火邪热，直奔上焦，势如走马耳。
牙痛者，阳明胃火也。宜内服清胃之剂，外用擦药，拔散火邪。然有气虚，脾胃
不足，或服寒凉过多，抑遏阳气于脾土之中，是以身反发热者，当以火郁汤，或补中
益气汤，不应则用八味地黄汤加牛膝、五味子以导下之，盖牙本骨之余，多属肾经虚火所致耳。

Zouma Gan (Running Horse Gangrene) is mostly caused by Qi deficiency with cold invasion, leading to stagnant heat accumulating internally; or due to long-term accumulation from consuming sweets, sour foods, salt, and greasy substances, causing accumulated heat to rush upward. This results in teeth becoming scorched, blackened, and rotting, occasionally bleeding clear blood. The blood gathers and turns into pus, which becomes foul-smelling and breeds "worms" (microbial erosion), eroding the mouth and teeth. In severe cases, it may perforate the cheeks, making breastfeeding and eating difficult, accompanied by asthma-like breathing and fever, leading to critical danger. The treatment method should involve internal administration of clearing and resolving agents to first remove accumulated heat. Externally, rinse with warm saline solution and insufflate medicines that eliminate saliva and draw out heat. One must absolutely avoid using purely cold-natured astringents, as this would prevent the stagnant heat from venting, causing deeper ulceration. It is named "Zouma" (Running Horse) because teeth belong to the Kidney. Once Kidney Qi is deficient, deficient fire and pathogenic heat rush directly to the Upper Jiao, moving with the speed of a running horse.
Toothache is primarily due to Stomach Fire in the Yangming channel. Internal administration of stomach-clearing formulas is suitable, along with external application of medicated powders to disperse fire pathogens. However, if there is Qi deficiency, insufficient Spleen and Stomach function, or excessive intake of cold-natured medicines suppressing Yang Qi within the Spleen Earth, resulting in contrary body fever, one should use Huoyu Tang (Fire-Stagnation Decoction) or Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction). If ineffective, then Bayi Dihuang Tang (Eight-Ingredient Rehmannia Root Decoction) added with Niuxi (Achyranthes Root) and Wuweizi (Schisandra Fruit) should be used to guide the heat downward. This is because teeth are considered the surplus of bone and are mostly caused by deficient fire in the Kidney channel.
Treatment for Kougan (Oral Gangrene):
Niuhuang (Calculus Bovis, 1 fen), Renzhongbai (Calculus Ureae, 4 fen), Qingdai (Indigo Naturalis, 4 fen), Bingpian (Borneolum Syntheticum, 1 fen), Xiangya (Homo Sapiens Elephantis Dentis Cornu, calcined to ash, 4 fen), Zhenzhu (Margarita, roasted in milk, 7 grains), Baimati (Equus Hemionus Hipparionis Unguis, calcined to ash, 4 fen), Huhuanglian (Coptidis Rhizoma var. chinensis), Xuexie (Draconis Sanguis, each 4 fen), Shexiang (Moschus, a small amount). Grind into fine powder. Clean the affected area with cold, strong tea and insufflate.
Treatment for Yagan (Gum Gangrene) and Toothache:
Shengma (Cimicifugae Rhizoma, 6 fen), Shigao (Gypsum Fibrosum, 1 qian 2 fen), Lianqiao (Forsythiae Fructum, 1 qian), Shengdi (Rehmanniae Radix Praeparata, 1 qian 2 fen), Niubangzi (Arctii Fructum, 1 qian, ground), Danpi (Moutan Cortex, 8 fen), Jiegeng (Platycodonis Radix, 4 fen), Gancao (Glycyrrhizae Radix et Rhizoma, 3 fen), Jingjie (Schizonepetae Spica, 4 fen), Bohe (Menthae Haplocalycis Herba, 4 fen). Add Dengxincao (Junci Medullae) and decoct in water.
Qingdai (Indigo Naturalis), Lvhui (Aloe), Hulian (Coptidis Rhizoma var. chinensis), Huangbai (Phellodendri Cortex), Ercha (Camelliae Sinensis Folium processed), Pengsha (Borax, each 5 fen), Bingpian (Borneolum Syntheticum, 1 fen). Use cold, strong tea to clean the mouth and insufflate. This formula is extremely effective for treating pediatric Zouma Yagan (Pediatric Running Horse Gum Gangrene); without timely treatment, rapid necrosis leads to death.
Use Baigou (White scale from women's urinal, calcined, 1 qian), Tonglv (Chlorocopperum, 2 qian), Shexiang (Moschus, 1 fen), Bingpian (Borneolum Syntheticum), Niuhuang (Calculus Bovis, each 1 fen). Grind finely and apply to the affected area for immediate cure.
