若用常方难拟愈活
治疗小儿走马疳，牙齿溃烂甚至崩砂出血、牙齿脱落的情况，参考兰香散方：
轻粉（一两重） 兰香子（一两，研末） 蜜陀僧（半两，用醋渣研磨成末）
以上药物研成粉末，涂抹于牙齿及牙龈上，立即见效。
按语说：婴儿患病症状繁多，疳病大多由于气机郁滞于三焦所致。疳病分为五脏，其中肾脏经常虚弱，患此疳病称为“急疳”，以“走马”为比喻，形容病情进展迅速，治疗困难。这类病症初期口臭，称为“臭息”；随后牙齿变黑，称为“崩砂”；严重时牙龈腐烂，称为“溃槽”；再严重则出血，称为“宣露”；最严重则牙齿自行脱落，称为“腐根”。既然牙根已经腐烂，如何能治愈呢？唉！富贵人家养育子女，以甘甜肥腻的食物喂养，导致孩子体内产生虚热；或者因为母亲在怀孕期间恣意食用珍馐美味，致使胎儿受到不良影响，这并非偶然发生。现将秘方陈述如下：
又一方：传齿立效散
鸭嘴胆矾（一两重，放在匙上烧至发红后研磨） 麝香（少许）
以上药物研匀，每次取少量涂抹于牙齿和牙龈上。（另一方法使用蟾酥一字的量，加入麝香混合均匀敷用）
按语说：血液的流行属于营气，气的循环属于卫气。小儿在变蒸期之后，饮食之间深恐损伤营卫而引发各种疾病。如果气被毒邪所伤，血被热毒所伤，热毒攻伐虚弱的脏腑，哪个脏腑虚弱，热邪就依附于哪个脏腑。大概小儿的肾脏这一脏常主虚弱，不可让热毒攻袭肾脏，从而损伤筋骨。只有牙齿承受骨骼之余气，所以首先发病，称为“走马疳”，因为它不是缓慢发作的，适宜服药治疗。外用可用露饮地黄膏、化毒丹、消毒饮等；外症以前文提到的立效散及麝酥膏涂抹。切忌给予食用热毒性质的食物。这种疳病不同于一般病症，它属于“无辜疳”，医生应当深入探究，保全患儿生命为上策。如果使用常规方剂，难以治愈。
治疗肾疳伴有口臭症状的良好方剂：
天麻 木香 独活 防风 麝香（少许，细研为末，混合进去）
以上各药一两重，研成粉末。每次服用一汤匙的量，年幼者减半，用麦门冬煎煮的熟水调服。
To treat infantile *Zouma Gan* (Running Horse Cancri, a rapidly progressing form of cancrum oris), where teeth are ulcerated, leading to "Bengsha" (bleeding like crumbling sand) and tooth loss, refer to the Lanxiang San formula:
Qingfen (Calomelas, 1 liang weight) Lanxiangzi (Basil Seeds, 1 liang, ground into powder) Miduoseng (Litharge, 0.5 liang, ground into powder using vinegar residue)
Grind the above ingredients into a fine powder and apply to the teeth and gums for immediate effect.
Commentary: Infants suffer from various symptoms; *Gan* disease is largely caused by Qi stagnation in the Triple Burner. *Gan* is categorized by the five Zang organs, with the Kidney often being deficient. When this deficiency leads to *Gan*, it is called "Ji Gan" (Urgent Gan), metaphorically described as "running horse" to indicate its rapid progression and difficult treatment. In this condition, initial halitosis is called "Chou Xi"; subsequently, teeth turn black, called "Bengsha"; severe gum erosion is called "Kui Cao"; further severity with bleeding is called "Xuan Lu"; and the most severe stage with spontaneous tooth loss is called "Fu Gen". Once the root is rotted, how can it be healed? Alas! Wealthy families nourish children with sweet, rich, and fatty foods, causing internal empty heat; or due to the mother consuming delicacies during pregnancy, affecting the fetus. This is not accidental. The secret formula is presented below:
Another Formula: Chuan Chi Li Xiao San (Teeth-Smearing Immediate Effect Powder)
Yazui Danfan (Alum Stone, 1 liang weight, heated on a spoon until red, then ground) Shexiang (Musk, a small amount)
Grind uniformly. Apply a small amount to the teeth and gums each time. (Another method uses Chan Su [Toad Venom] equivalent to one character, mixed with Musk and applied).
Commentary: The circulation of blood belongs to Ying (Nutritive Qi), and the circulation of Qi belongs to Wei (Defensive Qi). After the period of Bian Zheng (transformation and steaming), deep concern exists that diet may injure Ying and Wei, causing various diseases. If Qi is injured by toxins and Blood by hot toxins, these attack deficient Zang organs. Whichever Zang is deficient, heat attaches to it. Generally, the Kidney in infants is always prone to deficiency; it must not be attacked by hot toxins, which would damage sinews and bones. Teeth receive the residual Qi of bones, so they are the first to manifest disease, named "Zouma" (Running Horse) because it does not develop slowly. Medication is appropriate. Externally, use Luyin Dihuang Gao, Huadu Dan, Xiaodu Yin, etc. For external symptoms, apply the previously mentioned Li Xiao San and She Su Gao. Strictly avoid giving food with hot-toxic properties. This type of Gan differs from common conditions; it is related to "Wugu Gan" (Innocent Gan). Physicians should investigate deeply, prioritizing the preservation of life. Using standard formulas makes cure difficult.
Good Formula for Treating Kidney Gan with Halitosis:
Tianma (Gastrodiae Rhizoma) Muxiang (Aucklandiae Radix) Duhuo (Angelicae Pubescentis Radix) Fangfeng (Saposhnikoviae Radix) Shexiang (Musk, a small amount, finely ground and mixed in)
Each herb weighs 1 liang. Grind into powder. Take 1 tablespoon per dose; reduce to half for younger children. Mix with cooked water prepared from Maimendong (Ophiopogonis Radix) and swallow.
