治疗喉部疾病，使用吹药是外治法的关键。对此不可不深入探究。因为外科医生往往不了解药物性质，配制几种通用的药物。如果遇到重症，不仅无效，甚至会导致误事。况且喉症所用的吹药，更应当根据症状进行配伍。各味药材预先研磨成极细的粉末，这样药物才能与病症相对，疗效才能迅速显现。
初期出现肿痛、牙关紧闭、痰涎上涌的情况，适宜使用玉枢丹。用茶水磨开漱口，或者使用牙皂来开启牙关，或者用桐油蘸鹅毛管伸入喉中，引出痰液，这样关节窍道通畅后就能进食了。如果牙关紧急，强行撬不开，可以将牙皂研成末，吹入鼻内，嘴巴就会张开。或者将藜芦末吹入鼻孔，也能通过呕吐痰液来开启牙关。或者用生半夏擦拭两颊的车穴（颊车穴），也都有效。
如果脓已成且肿胀，在患处点破，排出脓毒和恶血。如果畏惧刀针，可以用人指甲、壁钱（一种蜘蛛）、瓦片上焙烧枯干后研成末，加入少许冰片，吹入患处，也能起到穿破排脓的作用，名为代刀散。
如果肿痛且痰壅盛，将玉枢丹、土牛膝根、万年青根捣汁，滴入二三滴醋含漱，效果最好。硼砂、朴硝、胆矾、牛胆汁、硝矾，都能消肿、化毒、去腐。如果红肿火气旺盛，则使用黄连、黄芩；青鱼胆、青黛、西瓜霜，都能清火解毒。如果是风火上壅，适宜使用薄荷、僵蚕、冰片、青黛等具有清凉疏散作用的药物。如果毒邪炽盛，适宜使用西牛黄、雄精、人中白，这些都是解毒的良药。
如果溃烂且新肉不生，适宜使用珍珠、西黄（麝香）、朱砂、琥珀之类药物来生肌长肉。但必须等到腐肉完全去除后才能使用。如果腐肉未去，就使用生肌等药物，反而会导致毒邪内伏，无法痊愈。这一点应当知晓。治疗喉症应用的药品并不多，了解药性并根据症状配合使用，自然灵妙异常，能在顷刻间挽救危重病症。
The application of insufflation powders (Chui Yao) is the key external treatment for throat diseases. This requires deep investigation. Surgeons often lack knowledge of drug properties, preparing several general-purpose remedies. When encountering severe cases, these are not only ineffective but may also lead to medical errors. Moreover, insufflation powders for throat diseases must be compounded according to specific symptoms. Each ingredient should be pre-ground into an extremely fine powder so that the medicine corresponds precisely to the condition, thereby achieving rapid efficacy.
In the initial stage, presenting with swelling, pain, trismus (lockjaw), and upward surging of phlegm-saliva, Yushu Dan (Jade Pivot Pill) is appropriate. It can be ground in tea water for gargling, or Ya Zao (Gleditsia sinensis fruit) can be used to open the jaw. Alternatively, using tung oil (Tung Oil) dipped on a goose feather quill to insert into the throat and induce vomiting of phlegm will clear the orifices, allowing resumption of diet. If trismus is severe and cannot be forced open, Ya Zao powder can be insufflated into the nose, causing the mouth to open. Alternatively, Li Lu (Veratrum nigrum rhizome) powder insufflated into the nostrils can also induce expectoration and open the jaw. Rubbing Ban Xia (Pinelliae Rhizoma) on both sides of the cheek (Jiache acupoint) is also effective.
If pus has formed causing swelling, the affected area should be punctured to drain pus, toxins, and bad blood. If one fears needles or scalpels, human fingernails, Bi Qian (a type of spider web), and tiles baked until dry and charred can be ground into powder, mixed with a small amount of Bing Pian (Borneolum Syntheticum), and insufflated into the lesion. This can also penetrate and drain, known as Da Dao San (Knife Replacement Powder).
For swelling, pain, and severe phlegm obstruction, crushing Yushu Dan, Tu Niu Xi Gen (Achyranthes bidentata root), and Wan Nian Qing Gen (Rhododendron molle root) to extract juice, adding two or three drops of vinegar, and holding it in the mouth is optimal. Peng Sha (Borax), Pu Xiao (Mirabilite), Dan Fan (Alumen), Niu Dan (Bovis Gallus), and Xiao Fan (Alums) can all reduce swelling, resolve toxins, and remove necrotic tissue. For redness, swelling, and excessive fire-heat, Huang Lian (Coptidis Rhizoma) and Huang Qin (Scutellariae Radix) are suitable. Qing Yu Dan (Green Fish Gallbladder), Qing Dai (Indigo Naturalis), and Xi Gua Shuang (Watermelon Frost) can all clear fire and resolve toxins. For wind-fire surging upward, Bo He (Menthae Haplocalycis Herba), Jiang Can (Bombyx Batryticatus), Bing Pian (Borneolum Syntheticum), and Qing Dai (Indigo Naturalis) etc., which have cooling and dispersing properties, are appropriate. For severe toxicity, Xi Niu Huang (Indian Bovis Calculus), Xiong Jing (Realgar), and Ren Zhong Bai (Human Urine Sediment) are excellent detoxifying agents.
For ulcers where new flesh does not grow, Zhen Zhu (Pearl), Xi Huang (Moschus), Zhu Sha (Cinnabaris), and Hu Po (Amber) etc., which promote tissue regeneration, are suitable. However, they must only be used after all necrotic tissue has been removed. If necrotic tissue remains and regenerative medicines are applied, it may instead cause toxins to linger internally, preventing healing. This point must be understood. The number of drugs required for treating throat diseases is not large. Understanding their properties and compounding them according to symptoms naturally yields extraordinary efficacy, rescuing critical conditions in an instant.
