骨槽风、牙疳奇方
古庙屋上多年干猫屎白色者，取来阴阳瓦焙存性，每一钱加冰片二分，研细收
贮。每用浓松萝茶洗净，然后吹之蚀烂处，自生肌收口。
冯鲁瞻曰∶重龈者，初生贴着齿龈有物胀起者是也。此候乃脾胃挟热，气血不
能收敛。治法速宜绵缠长针露锋，刺肿之处去其恶血则消，若再生再刺，否则有妨
乳食。总缘小儿出胎之后，血气收敛成血，则口内、舌上、喉颊皆净；若血气不敛，胎
毒上攻，则乃成矣。（《锦囊》）
冯鲁瞻曰∶男子八月而生齿，八岁而 ；女子七月而生齿，七岁而 。有齿迟
者，乃禀受肾气不足而髓不强。齿为骨余，骨之所络而为髓，髓不足故不能上充于齿
而迟也。若能调气血，固本复元，则齿自生而骨力坚凝矣。（《锦囊》）
长齿法（岐天师）
雄鼠脊骨（全副，余骨不用，尾亦不用，头亦不用，肉亦不用，新瓦上焙于，不用烧焦，留其生气也）
熟地黄（须亲身用竹片挖取生地黄，用瓦器煮熟，身怀令干为末，三钱。如市卖地黄，经铁针穿孔者，即不效
矣） 北细辛 榆树皮（各三分） 青盐（二钱） 杜仲 当归（各一钱）
忌犯铁器，共研细末。用一瓷瓶盛之，每日五更时不可出声，将此药轻擦在无牙
之处三十六擦，药任其咽下。不可用水漱口，一月如是。日间午间擦之更佳，亦如
前数，但经铁器便不效矣。
齿痛落去复生法
胆矾研细，人乳和搽孔中，日三四次，俱用新汲水漱净。久之其齿复生。
Miraculous Prescription for Bone Trough Wind and Dental Gangrene
Take the white, dried cat feces that have been stored for many years on the roof of an ancient temple. Roast them on a Yin-Yang tile until they retain their medicinal properties (Cun Xing). For every qian (approx. 3.7g) of this material, add 2 fen (approx. 0.74g) of Borneol (Bingpian), grind into a fine powder, and store in a sealed container. Before each use, rinse the mouth thoroughly with strong Songluo tea, then insufflate the powder onto the ulcerated and necrotic areas. This will promote tissue regeneration and wound closure naturally.
Feng Luzhan stated: "Chong Yin" (Double Gingiva) refers to the condition where, at birth, a swelling protrudes from the area adhering to the gums. This condition arises because the Spleen and Stomach harbor heat, preventing the Qi and Blood from consolidating. The treatment should promptly involve wrapping a long needle with cotton thread, exposing the tip, and pricking the swollen area to drain the evil blood; the swelling will subside. If it recurs, prick again; otherwise, it will hinder nursing. Ultimately, after birth, if the Qi and Blood consolidate to form blood, the oral cavity, tongue, throat, and cheeks remain clean. If the Qi and Blood fail to consolidate, fetal toxins attack upward, resulting in this condition. (From *Jinnang*)
Feng Luzhan stated: Males begin teething at eight months and change teeth at eight years old; females begin teething at seven months and change teeth at seven years old. Delayed teething is due to insufficient congenital Kidney Qi and weak Marrow. Teeth are considered the surplus of bones; bones connect to generate Marrow. Insufficient Marrow cannot ascend to nourish the teeth, causing delayed eruption. If one can regulate Qi and Blood, consolidate the root, and restore primordial vitality, teeth will grow naturally, and bone strength will become firm and consolidated. (From *Jinnang*)
Method for Promoting Teething (by Patriarch Qi)
Dorsal vertebrae of a male rat (the entire spine; do not use other bones, tail, head, or meat. Roast on a new tile until dry, but do not burn to charcoal; preserve its vital energy.)
Prepared Rehmannia Root (Shu Dihuang) (Must be personally excavated as fresh Rehmannia Root using a bamboo tool, cooked in a clay vessel, dried by keeping it close to the body, then ground into powder. Dosage: 3 qian. If purchased market Rehmannia has been pierced with iron needles, it will be ineffective.)
Northern Asarum (Beixixin)
Elm Bark (Yupishu) (Both: 3 fen)
Blue Vitriol / Copper Sulfate (Qingyan) (2 qian)
Eucommia Bark (Duzhong)
Angelica Sinensis (Danggui) (Both: 1 qian)
Avoid contact with iron vessels. Grind all ingredients together into a fine powder. Store in a porcelain bottle. At the fifth watch (early morning, approx. 1-3 AM), without making any sound, gently rub this medicine onto the edentulous area thirty-six times. Allow the patient to swallow the medicine. Do not rinse the mouth with water. Continue this for one month. Rubbing during midday is also effective, following the same count, but avoid any contact with iron, as it renders the remedy ineffective.
Method for Regrowth of Fallen Teeth
Grind Alum (Danfan) into a fine powder. Mix with human milk and apply into the tooth socket three to four times daily. Rinse thoroughly with freshly drawn water each time. After a prolonged period, the tooth will regrow.
