白僵蚕直者不拘多少，炒为末，以生姜自然汁调服一钱匕。吴内翰 《备急方》云，余
尝苦此，用之甚效。葛彦恢提举阁中曾患喉痹，五八主簿用此方治之即安。一方调下二钱，
未通，半时许再服，立通，吐出顽涎，别将大黄一块慢火炮熟，打扑尽灰，如一米浓，切片，
以两
仰坐，令人呷药在口，以笔管注入鼻中，男左女右，注药讫，随即扶令正坐，须臾吐涎，不
即扶起，恐吐自鼻中出也，吐了含咽大黄如前。
治缠喉风神效。
盆梢（一两，研） 白僵蚕（半两，去丝） 青黛（一钱，研） 甘草（二钱半，生）
上为细末，以少许掺喉中。如闭甚，以竹管吹入，寻常咽喉间不快亦可用。
沈司理传。
白矾（二两，捣碎） 巴豆（半两，略捶破）
上同于铫器内炒，候矾枯，去巴豆不用，碾矾为细未，遇病以水调灌，或干吹入咽喉中。
又方
朴硝研细 黄丹飞过，细研
上相拌和深粉红色，遇病用芦管或笔管以半钱许吹入喉中即破，吐涎而愈，甚者不过两
次。
又方
蛇皮一条，新瓦上炒焦黄带黑色，碾细入麝香少许，干掺口内。
开口不得者。
上以黄腊纸裹巴豆一个，如患人鼻孔大小，中心切破，急以塞鼻，气冲入喉中自破也，
已觉通利即除去。濠守王亚夫方，巴豆去壳，拍碎，以绵裹，随左右纳鼻中，即吐出恶物，
后鼻中或生少疮亦无害（原版鼻上有“用”字）。
白僵蚕（Bombyx Batryticatus）选用直挺的，数量不限，炒制后研成粉末。用生姜榨取的天然汁液调和，每次服用一钱匕（古代量器，约相当于现代的一小勺）。吴内翰在《备急方》中记载：我曾经深受此病困扰，使用此方效果显著。葛彦恢担任阁中提举时曾患喉痹（咽喉肿痛闭塞之症），五八主簿用此方治疗，患者立刻感到安宁。另一用法是调服二钱，若服药后痰涎未通，约半时辰后再服一次，立刻通畅，吐出顽固的痰涎。另外取大黄一块，用慢火炮熟，捣碎成灰烬状，质地如米汤般浓稠，切成薄片。让患者仰卧，让人将药含在口中，用笔管将药液注入鼻中，男性注左侧鼻孔，女性注右侧鼻孔。注药完毕后，随即扶患者端正坐起，片刻后会吐出痰涎。如果不立即扶起，恐怕痰涎会从鼻孔流出。吐完后，含咽之前处理好的大黄片。
此方对治疗缠喉风（一种以咽喉红肿疼痛、呼吸困难为特征的急症）有神奇疗效。
配方：盆梢（一两，研磨）、白僵蚕（半两，去除丝状物）、青黛（一钱，研磨）、甘草（二钱半，生用）。
以上药材制成细末，取少量撒入喉中。如果喉部闭塞严重，用竹管吹入；寻常咽喉间的不适也可使用。
此方由沈司理传授。
配方：白矾（二两，捣碎）、巴豆（半两，略加捶破）。
以上药材一同在铫器（一种煎药器具）内炒制，待白矾炒枯后，去掉巴豆不用，将白矾碾成细末。遇到病患时，用水调和灌服，或干药粉吹入咽喉中。
又一方：
朴硝（研磨细）、黄丹（经过飞制工艺，即反复加热升华以去毒，再细研）。
以上两者混合拌和至深粉红色，遇病时用芦管或笔管取半钱许的药粉吹入喉中，即可使病灶破裂，吐出痰涎而痊愈，严重者不过两次。
又一方：
蛇皮一条，在新瓦上炒至焦黄带黑色，碾细后加入少许麝香，干药粉掺入口内。
针对张口困难者。
以上方法：用黄腊纸包裹一个巴豆，大小与患者鼻孔相当，中心切破，紧急时塞入鼻孔，热气冲入喉中，病灶自会破裂。一旦感觉通畅，立即取出。这是濠州太守王亚夫的方子：巴豆去壳，拍碎，用棉布包裹，根据病情左右侧塞入鼻中，即可吐出恶浊之物，之后鼻孔中即使长出少量疮疡也无妨害（原版在“鼻”字上有“用”字）。
*White silkworm* (Bombyx Batryticatus) that are straight in shape, regardless of quantity, are stir-fried and ground into powder. It is taken orally with fresh ginger juice, one *qianbi* (an ancient measuring unit for medicine, roughly equivalent to a small spoonful). Wu Nei Han recorded in "Bei Ji Fang" (Emergency Formulas): "I once suffered from this condition, and using this formula was very effective." Ge Yanhui, who served as the Supervisor of the Pavilion, once suffered from *hou bi* (throat obstruction characterized by swelling and pain). The Chief Clerk Wuba treated him with this formula, and he felt immediate relief. Another method involves taking two *qian* doses; if there is no relief after administration, take another dose after half an hour (*ban shi xu*). This will immediately clear the obstruction, expelling stubborn phlegm. Additionally, take a piece of *Dahuang* (Rhei Radix et Rhizoma), slow-roast it until cooked, crush it into ash, achieving a consistency thick like rice gruel, and slice it. Have the patient lie supine. Let someone hold the medicine in their mouth and inject it into the nasal cavity using a pen tube. For males, use the left nostril; for females, the right. After injection, promptly help the patient sit upright. Phlegm will be expelled shortly. If not helped up immediately, the phlegm might flow out through the nose. After spitting, swallow the previously prepared slices of *Dahuang*.
This formula is miraculous for treating *chan hou feng* (a severe acute throat condition characterized by swelling, pain, and difficulty breathing).
Formula: *Penshao* (1 liang, ground), *Baishangcan* (0.5 liang, silk removed), *Qingdai* (1 qian, ground), *Gancao* (2.5 qian, raw).
Grind all ingredients into a fine powder. Sprinkle a small amount into the throat. If the obstruction is severe, blow it in using a bamboo tube. It can also be used for general discomfort in the throat.
Transmitted by Shen Sili.
Formula: *Baifan* (Alum, 2 liang, crushed), *Badou* (Crotonis Fructus, 0.5 liang, slightly bruised).
Stir-fry both ingredients together in a *diao* (a type of cooking vessel). When the alum becomes dry and brittle, remove and discard the *Badou*. Grind the alum into a fine powder. When needed, mix with water for oral administration, or blow the dry powder into the throat.
Another Formula:
*Miaoxiao* (Natrii Sulfas, finely ground), *Huandan* (Minium, processed by sublimation [fei], then finely ground).
Mix these two ingredients thoroughly until they form a deep pink color. When needed, use a reed tube or pen tube to blow about half a *qian* of the powder into the throat. This will cause the lesion to rupture, expelling phlegt and leading to recovery. Severe cases may require no more than two applications.
Another Formula:
One snake skin, stir-fried on a new tile until scorched yellow with black spots, ground into a fine powder. Add a small amount of *Shexiang* (Moschus). Apply the dry powder directly into the mouth.
For patients unable to open their mouths:
Wrap one *Badou* (Crotonis Fructus) in yellow wax paper. Size it to match the patient's nostril. Make a slit in the center. Insert it urgently into the nostril. The heat/qi will rush into the throat, causing the obstruction to rupture. Remove it as soon as relief is felt. This is the formula of Wang Yafu, Prefect of Haozhou: Shell the *Badou*, crush it, wrap it in cotton, and insert it into the left or right nostril depending on the condition. This will expel foul matter. Even if minor sores develop in the nostril afterward, it is harmless. (The original edition has the character "yong" [use] above the word "nose").
