【鼻渊】即脑漏的初期表现。由于风寒之邪凝滞侵入脑户，与太阳经的湿热相互交蒸，从而形成此病。症状为鼻流清涕，或流出黄色液体，点点滴滴，长期湿润不干。治疗方药：白芷（一两）、苍耳子（炒制）、辛夷仁、薄荷（各五钱五分），共研为细末。江鱼牙（煅烧存性并研细）：取少量吹入鼻中，患者仰卧，每次一二分；再用茯苓（一两）研细，与上述药物混合均匀，每次服用三钱，用温开水送下。若鼻中时时流出臭秽的黄水，说明有虫进入脑中。治疗方法：取丝瓜藤靠近根部三五尺长的一段，晒干后烧至存性并研细，每次服用一钱，用温酒调服，以痊愈为度。
【鼻塞不通】无论是外感病症，还是内火炽盛所致，均可使用通草、细辛、炮附子（各一钱），研成细末，用蜂蜜制成丸剂，用棉布包裹后塞入鼻孔，片刻即可通畅。或者使用石菖蒲、牙皂荚（各一钱），研成细末，用棉布包裹后塞入鼻孔，即刻通畅。
【鼻生息肉】凡是患息肉，多因饮食积滞于胃中，热痰流注所致。适宜内服消痰的药物，再加以外治，可以迅速见效。方法：用瓜蒂、细辛（各一钱，研细），用棉布包裹后塞入鼻中，以痊愈为度。或者取藕节（带根处一段），烧成灰并保存其药性，研细后吹敷患处，立见疗效。
【鼻痔】苦瓜蒂（四钱，炒制）、甘遂（炒制二钱）、枯矾、螺蛳壳、草乌尖（各五分），共同研为细末，用麻油调和做成一团。每次取一丸，放入鼻内点涂痔疮，使其化为臭水，每日一次，自然腐烂脱落。
【鼻疮】百草霜（研细三钱），用冷水调匀后服用。或者杏仁（去皮尖，研细），用人乳汁调和后搽涂患处。或者将桃叶嫩心捣烂，塞入鼻孔，即刻见效。
【酒渣鼻】硫黄（用豆腐水煮三次洗净，研细二钱）、轻粉（一钱）、密陀僧（一钱）、白芷（一钱）、杏仁（五分），共同研为细末，用唾液调和后搽涂患处。若病程长久不愈，可用大黄、朴硝，共同研为细末，用唾液涂抹。内服方：苦参、当归（各净末四两，混合均匀），用酒糊制成丸剂，大小如梧桐子，饭后用热茶吞服八十丸，药尽即愈。或者连翘心四两，每次取二三钱，泡汤当茶喝，即可痊愈。或者凌霄花、山栀子，等分为末，每次服用二钱，用清茶调服，每日两次。
[Nasal Sinusitis (Bi Yuan)] This is the initial stage of "brain leakage" (chronic purulent rhinitis). It arises because wind-cold pathogens condense and invade the brain gate, interacting with damp-heat in the Taiyang meridian to cause this affliction. Symptoms include a runny nose with clear mucus, or the discharge of yellow fluid, dripping drop by drop, remaining moist for a long time without drying. Prescription: Baizhi (Angelicae Dahuricae Radix, 1 liang), Cang'erzi (Xanthii Fructus, stir-fried), Xinyiren (Magnoliae Flos, stamen only), Bohe (Menthae Haplocalycis Herba) [each 5 qian 5 fen], ground into fine powder. Jiangyuya (Gobiocypris rarus, calcined to preserve carbonized nature and ground fine): Blow a small amount (1-2 fen) into the nostril while the patient lies supine. Then, take Fuling (Poria, 1 liang), grind it fine, mix evenly with the previous powder, and take 3 qian per dose with warm water. If foul-smelling yellow water flows from the nose from time to time, it indicates that insects have entered the brain. Treatment method: Take 3-5 chi of Si Gua Teng (Luffae Caulis) near the root, dry it in the sun, burn until carbonized but preserving efficacy, and grind fine. Take 1 qian per dose, mixed with warm wine, until cured.
[Nasal Congestion] Whether caused by external pathogenic factors or excessive internal fire, use Tongcao (Tetrapanacis Medulla), Xixin (Asari Radix et Rhizoma), and Paofuzi (Aconiti Lateralis Radix Praeparata) [each 1 qian]. Grind into fine powder, make pills with honey, wrap in cotton, and insert into the nostril; congestion will resolve immediately. Alternatively, use Shichangpu (Acori Tatarinowii Rhizoma) and Yazaojia (Gleditsiae Sinensis Fructus Spina) [each 1 qian], grind fine, wrap in cotton, and insert into the nostril for immediate relief.
[Nasal Polyps] Nasal polyps are generally caused by food stagnation in the stomach and the flow of phlegm-heat. Internal administration of phlegm-resolving agents combined with external treatment can yield rapid results. Method: Use Goudi (Cucumerit Semen, 1 qian) and Xixin (Asari Radix et Rhizoma, 1 qian), grind fine, wrap in cotton, and insert into the nostril until cured. Alternatively, take Oujie (Nelumbinis Node, a section with roots), burn to ash while preserving efficacy, grind fine, and blow onto the affected area for immediate effect.
[Nasal Hemorrhoids] Kugua Di (Momordicae Fructus Pedunculus, 4 qian, stir-fried), Gansui (Kansui Radix, stir-fried 2 qian), Kufan (Alumen), Luosike (Concha Viverrae), and Caowu Jian (Aconiti Kusnezoffii Radix Apex) [each 5 fen]. Grind all into powder, mix with sesame oil to form a paste. Use one pill-sized portion per application, insert into the nostril to treat the hemorrhoid, causing it to liquefy into foul-smelling fluid. Apply once daily until it naturally sloughs off.
[Nasal Ulcers] Baicaoshuang (Fuligo Silicea, 3 qian, ground fine), taken orally mixed with cold water. Alternatively, Xingren (Armeniacae Semen Amarum, peeled and cored, ground fine) mixed with human breast milk, applied topically. Alternatively, crush fresh peach leaf buds and insert into the nostril for immediate effect.
[Rhynophyma / Rosacea] Liuhuang (Sulfur, boiled three times in tofu, washed clean, 2 qian), Qingfen (Calomelas, 1 qian), Miduoseng (Litharge, 1 qian), Baizhi (Angelicae Dahuricae Radix, 1 qian), and Xingren (Armeniacae Semen Amarum, 5 fen). Grind all into powder, mix with saliva for topical application. For chronic cases that do not heal, use Dahuang (Rhei Radix et Rhizoma) and Puxiao (Natrii Sulfas), grind into fine powder, and apply with saliva. Internal prescription: Kushen (Sophorae Flavescentis Radix) and Danggui (Angelicae Sinensis Radix) [each 4 liang of purified powder, mixed evenly], made into pills with wine paste, size of paulownia seeds. Swallow 80 pills after meals with hot tea; cure upon finishing the medicine. Alternatively, use Lianqiao Xin (Forsythiae Fructus Cor) 4 liang, take 2-3 qian per dose, brew as tea and drink until cured. Alternatively, Lingxiaohua (Campsis Grandiflorae Flos) and Shanzhizi (Gardeniae Fructus), equal parts, ground into powder. Take 2 qian per dose, mixed with clear tea, twice daily.
