杨氏云∶由乳哺不调，脏腑伏热所致也。凡甘味入于脾而动虫，虫动则侵蚀脏
腑，遂使孩提心下扰闷，若上蚀齿龈则口疮出血，齿色紫黑，下蚀肠胃则下痢肛烂，
湿痒生疮，疗治不早，精髓消耗，难以有瘳，虫者 也，目为湿 ，多因疳伤久痢，
肠胃受湿得之。状如狐惑伤寒齿蚀之证，或以走马命名，盖齿属肾，肾主虚，才受
热邪，疳气直奔上焦，故以走马为喻，初作口气，名曰臭息。次第齿黑，名曰崩砂。
盛则龈烂，名曰溃槽。热血迸出，名曰宣露。甚者齿皆脱落，名曰腐根，其根既腐，
纵得全活，齿不复生。外证，脑热肌削，手足如冰，寒热时来，滑泄肚痛，口臭干
渴，齿龈生疮，爪黑面黧，身多疮疥是也。钱氏，地黄丸主之。仍当于生脉散中
多加黄 以补肺。曾氏，用调元散。

Yang Shi stated: This condition arises from improper breastfeeding and feeding, leading to latent heat within the zang-fu organs. Sweet flavors entering the Spleen generate parasites; when these parasites move, they erode the zang-fu organs, causing distress and oppression in the epigastrium of young children. If they erode upwards into the gums, it results in mouth sores with bleeding and purple-black teeth. If they erode downwards into the intestines and stomach, it leads to dysentery, anal erosion, dampness-induced itching, and sores. If treatment is not initiated early, essence and marrow are consumed, making recovery difficult. The term "Gan" (Pediatric Malnutrition Syndrome) refers to eyes clouded like a film (Mu Wei Shi Yi), often caused by prolonged diarrhea due to long-standing Gan syndrome, where the intestines and stomach are affected by dampness. The presentation resembles the tooth-erosion symptoms seen in Huhu Disease (Fox-Hydrargyrus-like disease) or Shanghan (Cold Damage). It is sometimes named "Zouma" (Running Horse) because teeth belong to the Kidney, which governs deficiency; upon exposure to heat pathogens, Gan Qi rushes directly to the Upper Jiao, hence the metaphor of speed. Initially, foul breath occurs, named "Chou Xi". Subsequently, teeth turn black, named "Beng Sha". When severe, gums rot, named "Kui Cao". Blood spurts out, named "Xuan Lu". In extreme cases, all teeth fall out, named "Fu Gen"; once roots rot, even if life is saved, teeth will not regrow. External signs include: hot head, emaciated muscles, cold hands and feet, alternating chills and fever, slippery diarrhea with abdominal pain, bad breath, dry mouth and thirst, gum sores, black nails, sallow complexion, and numerous skin sores and scabies. Qian Yi advocated using Dihuang Wan (Rehmannia Pill) as the primary treatment. Additionally, Huangqi (Astragalus Root) should be added in large amounts to Shengmai San (Generate the Pulse Powder) to tonify Lung Qi. Zeng Shirong advocated using Tiaoyuan San (Regulate Origin Powder).
