六味地黄丸：方剂见卷一胎疾门。
凉膈散：方剂见卷四舌病门。
如圣散：治疗小儿走马疳（一种发病迅速、腐蚀严重的口腔疾病），以及崩沙（牙龈萎缩暴露牙根）、宣露（牙齿松动脱落）。
用法：取妇人尿桶中的白色垢腻，刮下，在瓦片上烧至烟尽，取一钱；铜绿（碱式碳酸铜）二分；麝香半分。将以上药物共研为细末。先用蜡树叶浸泡在淘米水中洗净患处，然后涂抹此药。
宣风散：治疗睡梦中磨牙（切牙）。
配方：尖槟榔五钱，广陈皮一两五钱，炙甘草五钱。
制法与用法：共研为细末。每次服用一二钱，用蜜水调服，空腹服用。
鼠骨散：治疗小儿乳牙脱落后新牙不生。
用法：取雄鼠一只，去皮烂后，取出完整骨骼，烤焦研成细末，加入麝香一分，擦拭牙齿生长处，过一段时间后，用姜汤漱口。
对于牙龈溃烂，使用各种药物无效的情况，可用盐渍橄榄二三个，连皮带核在火中烧至存性（保留部分药性），加入冰片半分，涂抹患处，效果神奇。
治疗走马牙疳（口臭腐烂出血），取红枣三枚去核，填入明雄黄（主要成分为二硫化二砷）研成的细末，放在新瓦片上，火中烧至存性，研成细末后涂抹患处。
又一方：凤凰衣（鸡蛋内膜）在未接触水的状态下，焙至黄色，少量加入枯矾（煅白矾），共研为细末涂抹患处。
《内经》说：咽喉是水谷进入的通道；喉咙是气息上下出入的地方。又说：一阴一阳之气郁结，称为喉痹（咽喉肿痛闭塞之证）。大概咽部连接胃管，主要接纳水谷且位置靠后；喉部连接肺管，专门主管呼吸且位置靠前，是人体一身的关键要害。如果胸膈间郁积热毒，导致产生风痰，壅滞不散，发作于咽喉，虽然病名众多，但无非都是热毒所致。应当迅速清热解毒，拖延则会有难以救治的祸患。轻症用甘桔汤（甘草与桔梗组成的方剂），重症用化毒汤。
如果是痘疮引起的咽喉痛，是毒气向上攻冲所致，使用加减甘桔汤。
喉中生疮，不能吸吮乳汁，使用化毒汤。
小儿被骨头卡住，骨头大难以下咽的，用鹅毛刺激咽喉催吐排出；骨头小的，用海上方治疗。
Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill): See the formula in Volume 1, Section on Fetal Diseases.
Liangge San (Cooling the Diaphragm Powder): See the formula in Volume 4, Section on Tongue Diseases.
Rusheng San (Like-Sage Powder): Treats children's gan gangrene (a rapidly progressing and severe oral disease), as well as gingival recession exposing tooth roots and loose teeth.
Usage: Scrape down the white sediment from a woman's urine bucket, burn it on a tile until no more smoke is produced, take one qian; take two fen of Chulv (Malachite, basic copper carbonate); take half a fen of Shexiang (Musk). Grind these together into a fine powder. First, wash the affected area with rice water infused with leaves of the Chinese tallow tree (Vernicia fordii), then apply this medicine.
Xuanfeng San (Dispersing Wind Powder): Treats bruxism (teeth grinding) during sleep.
Ingredients: Jianbinglang (Areca Seed, *Semen Arecae*) five qian, Guangchenpi (Tangerine Peel, *Pericarpium Citri Reticulatae*) one liang five qian, Zhigancao (Honey-fried Licorice Root, *Radix Glycyrrhizae Preparata*) five qian.
Preparation and Usage: Grind together into a fine powder. Take one or two qian per dose, mixed with honey water, taken on an empty stomach.
Shugusu San (Mouse Bone Powder): Treats delayed eruption of permanent teeth after the loss of deciduous teeth in children.
Usage: Take one male mouse, remove skin and flesh, extract the complete skeleton, roast until dry and brittle, grind into a fine powder, add one fen of Shexiang (Musk), apply to the site where teeth are growing, wait for a while, then rinse mouth with ginger soup.
For gum ulceration unresponsive to various medicines, use two or three salted olives, including peel and pit, roasted in fire until "preserving nature" (charred but retaining medicinal properties), add half a fen of Bingpian (Borneol), and apply to the affected area; this yields miraculous effects.
For treating gan gangrene (characterized by foul odor, rotting, and bleeding), take three red dates, remove pits, fill them with finely ground Mingxionghuang (Realgar, *Realgar*), place them on a new tile, roast in fire until "preserving nature," grind into powder, and apply topically.
Another prescription: Fenghuangyi (Chicken Eggshell Membrane), ensuring it has not touched water, bake until yellow, add a small amount of Kufan (Calcined Alum, *Alumen Ustums*), grind together into a fine powder and apply.
The *Classic* states: The pharynx (Yanhou) is the pathway for food and drink; the larynx (Houtong) is the passage for qi to ascend and descend. It also states: When Yin and Yang qi become knotted, it is called Houbi (throat obstruction/swelling). Generally, the pharynx connects to the stomach tube, primarily receiving food and drink, located posteriorly; the larynx connects to the lung tube, exclusively governing respiration, located anteriorly. Together, they are the vital hub of the entire body. If heat toxins accumulate in the chest and diaphragm, generating wind-phlegm that stagnates and fails to disperse, manifesting in the throat and pharynx, although there are many disease names, they are all essentially due to heat toxins. One must clear and resolve quickly; delay leads to incurable danger. For mild cases, Ganjie Tang (Licorice and Platycodon Decoction); for severe cases, Huadu Tang (Detoxification Decoction).
If throat pain occurs due to smallpox, it is caused by toxic vapors attacking upward; use Modified Ganjie Tang.
If sores form in the throat preventing suckling, use Huadu Tang.
If a child is choked by bone fragments, and the bones are large and difficult to swallow, use a goose feather to stimulate the throat to induce vomiting; if the bones are small, treat using formulas from Hai Shang (likely referring to external or folk remedies).
