咸腻之物。脾虽喜甘，积滞日久，蕴热上熏于口，致齿焦黑烂，间出清血，血聚成脓，脓臭
成虫，侵蚀口齿，甚至腮颏穿破，乳食不便，面色光浮，气喘热作，名走马牙疳。宜芦荟丸主
之，外用烧盐散、铜青散敷之。若经久不愈，敷于唇之上下，乃成硼砂证，或齿落骨露，饮食
减少，气促痰鸣，必致危矣。

走马牙疳，多因气虚感受外邪，以及体内有积滞停留不去，郁久化热，虚热之气上蒸，或者食用了甜、酸、咸、腻的食物。脾虽然喜好甘味，但积滞日久，蕴生湿热上熏于口，导致牙齿焦黑腐烂，间或流出清血，血液积聚化为脓液，脓液发臭滋生虫蚀，侵蚀口腔和牙齿，甚至腮部和下巴穿破，哺乳进食不便，面色光亮浮肿，气喘发热发作，这种病症称为走马牙疳。适宜用芦荟丸主治，外用烧盐散、铜青散敷贴患处。如果经久不愈，药粉敷在嘴唇上下，便形成硼砂证，或者牙齿脱落骨头外露，饮食减少，气短痰鸣，必定导致危重局面。

Zouma Yagan (Horse-running Gangrene of the Teeth) is mostly caused by Qi deficiency with pathogenic invasion, as well as retained food stagnation that lingers and does not dissipate. Accumulated heat transforms into warmth, and deficient heat qi steams upward, or it results from consuming sweet, sour, salty, or greasy foods. Although the Spleen favors sweet flavors, long-term stagnation breeds heat that steams upward to the mouth, causing teeth to turn black and rot, with clear blood occasionally oozing out. Blood accumulates to form pus, which becomes foul-smelling and breeds worms that erode the oral cavity and teeth. In severe cases, the cheeks and chin may perforate, making breastfeeding and eating difficult. The complexion appears shiny and puffy, with panting and fever attacks. This condition is named Zouma Yagan (Horse-running Gangrene of the Teeth). It should be primarily treated with Lushui Wan (Aloe Pill), and externally applied with Shaoyan San (Burnt Salt Powder) or Tongqing San (Chlorite Powder). If it persists without healing, applying powder above and below the lips leads to Pengsha Zheng (Borax Syndrome), or teeth fall out with bone exposure, reduced diet, shortness of breath, and phlegm rattle, inevitably leading to a critical state.

Mix with rice washing water and apply inside the mouth.)
Shaoyan San: Treats pediatric Zouma Yagan (Horse-running Gangrene of the Teeth) with flesh ulceration and black rot.
Xiangdou (Quercus Fructus Shell) Yan Shi (Sodium Chloride) Shexiang (Moschus)
Take large Xiangdou (Quercus Fructus Shell), fill with Yan Shi (Sodium Chloride), seal two shells together, or five to seven shells. Place them in charcoal fire and burn thoroughly along with the salt. Remove and place on the ground, covering with a tile to extinguish fire toxicity. After cooling, take out and grind into powder. Add a small amount of Shexiang (Moschus) and grind together into an extremely fine powder. Mix with rice washing water for application. Do not wrap in paper; store in a tile box, as the salt content maintains moisture.
Generally, children's Zang-Fu organs are fragile. Overconsumption of milk and food damages the Spleen and Stomach. It is crucial to regulate properly, avoiding excess or deficiency. Otherwise, damage to the Spleen and Stomach results in a pale complexion, cold air in the mouth, loss of appetite for milk and food, vomiting, emaciation, weakness, and abdominal pain. In such cases, one should tonify the Spleen and benefit the Stomach. For all people, Stomach Qi is the root; treating disease is no different. Stomach Qi can be deficient or excess. Deficiency presents with vomiting and inability to eat; excess presents with fullness and internal heat. Deficient conditions require tonification, while excess conditions require purgation. Achieving balance is the goal. Pingwei San (Peaceful Stomach Powder), Guanyin San (Guanyin Powder), and Yihuang San (Yellow-Enhancing Powder) are essential formulas for strengthening Stomach Qi and can be used to treat according to syndrome differentiation.
