【方歌】鼻疔生长在鼻孔内部，鼻窍肿胀阻塞并牵引脑门疼痛，严重时嘴唇和腮部都会出现浮肿，这是肺经火毒在蟾离宫（指面部特定区域或病位）作祟。
【注】此证生于鼻孔内，鼻窍肿胀堵塞，胀痛牵引至脑门，严重时嘴唇和腮部都发生浮肿，由肺经火毒凝结而成。适宜用蟾酥丸发汗治疗，再用蟾酥丸研成细末，吹入鼻窍。如果肿胀坚硬向外扩散，用离宫锭涂抹患处。此证初起时，必须迅速治疗，延误则毒气内攻，导致神志昏迷、呕吐呃逆，鼻子肿得像瓶子一样的是逆证（预后不良）。

【方歌】鼻渊表现为浊涕流出鼻孔，久病则淋沥出血水且气味秽臭腥臊，因胆热移于脑部，兼感风寒凝郁化火所致，若虫蚀脑髓则名为控脑砂。
【注】此证内因为胆经之热，移于脑髓，外因为风寒凝滞郁结化火而成。鼻窍中时常流出黄色浊涕，适宜服用奇授藿香丸。如果久治不愈，鼻中淋沥出腥臭的血水，伴有头晕虚眩而痛者，必定是虫蚀脑髓，即名为控脑砂，适宜服用天罗散。但是此证日久必然导致正气虚弱，应当兼服补中益气汤即可见效。

[Formula Song] Bi Ding (Nasal Carbuncle) arises within the nasal cavity; swelling of the nasal orifice radiates pain to the forehead. In severe cases, the lips and cheeks become edematous, caused by Fire-Toxin in the Lung Meridian affecting the area of Chan Li Gong.
[Annotation] This condition originates inside the nostrils, with swelling and obstruction of the nasal passages, distending pain radiating to the forehead, and in severe cases, edema of the lips and cheeks. It is formed by the coagulation of Fire-Toxin in the Lung Meridian. It is appropriate to administer Chansu Wan (Toad Venom Pill) to induce sweating, and then crush Chansu Wan into a fine powder and insufflate it into the nasal orifice. If the swelling becomes hard and spreads outward, apply Ligong Ding (Ligong Plaster/Paste). At the initial stage of this condition, prompt treatment is required; delay allows the Toxin Qi to attack inward, leading to coma, vomiting, and retching. Nasal swelling resembling a bottle indicates an adverse prognosis (Ni syndrome).
Formulas: Chansu Wan (see section on Ding Chuang/Carbuncles); Ligong Ding (see section on Zhongyang/Swelling Ulcers).
[Formula Song] Bi Yuan (Nasal Sinusitis) presents with turbid discharge flowing from the nose; prolonged cases involve dripping bloody fluid that is foul-smelling and fishy. This results from Gallbladder Heat transferring to the brain, combined with Wind-Cold stagnation transforming into Fire. If worms erode the brain marrow, it is named Kong Nao Sha.
[Annotation] The internal cause is Heat in the Gallbladder Meridian transferring to the brain marrow; the external cause is Wind-Cold stagnation and郁 (stagnation) transforming into Fire. Yellow turbid discharge frequently flows from the nasal orifices; Qishou Huoxiang Wan is appropriate for oral administration. If the condition persists without cure, and bloody fluid with a foul smell drips from the nose, accompanied by dizziness, deficiency vertigo, and pain, it must be due to worms eroding the brain marrow, named Kong Nao Sha. Tianluo San is appropriate for oral administration. However, prolonged illness inevitably leads to Deficiency; therefore, Buzhong Yiqi Tang should be taken concurrently for efficacy.
Formula: Qishou Huoxiang Wan
Composition: Huoxiang Lian Zhiye (Agastache with stems and leaves, 8 liang)
Grind into a fine powder, mix with bile from a male pig to form pills the size of Sophora seeds. Take 5 qian per dose, administered after meals with Xiancao Zi Decoction (Cocklebur Seed Decoction) or washed down with yellow wine.
[Formula Song] Qishou Huoxiang Wan treats nasal discharge from Bi Yuan; turbid drip persists long without cessation. Pig bile mixed with Huoxiang powder, taken with Cocklebur Tea, cures the affliction.
Another Formula: Tianluo San
Composition: Sigua Teng (Vine of Luffa, preferably near the root, calcined to retain charred nature)
Grind into powder. Use 3 qian per dose, taken after meals with yellow wine.
[Formula Song] Tianluo treats worms eroding brain marrow causing headache; nose bleeds with foul-smelling bloody fluid. Calcined Luffa root ground to fine powder, mixed with yellow wine for ingestion, habitually kills worms.
Another Formula: Buzhong Yiqi Tang (see section on Kuiyang/Ulcerated Sores)
