《圣济总录》中称之为“呷”。症状表现为咳嗽，且胸中痰液积聚于喉间，随着呼吸时气与痰相互搏击，发出呀呷的声音。治疗使用射干丸。该方由射干、半夏、陈皮、百部、款冬花、细辛、干老姜、五味子、贝母、茯苓、郁李仁各一两组成，皂荚刮去皮和子后炙制五钱。将上述药材共研为末，用蜂蜜制成如梧桐子大小的丸剂。空腹时用米汤送服三十丸，每日服用两次。
脉象以浮滑为吉，忌讳短涩、代脉或散脉。
我按语认为：哮喘这一疾病，是寒邪潜伏在肺俞穴处，痰窠结聚在肺膜上，内外相应。一旦遇到风、寒、暑、湿、燥、火六气的伤害就会发作；饮酒过度或饮食不节也会发作；发怒或情绪激动也会发作；劳累过度或房事不节也会发作。一旦发作，肺俞处的寒气与肺膜处的浊痰便狼狈为奸，阻塞气道，导致无法呼吸，而呼吸时的正气又触动痰液，发出鼾声。这不是普通药物所能治疗的。所以《圣济总录》使用前方（射干丸）这样峻烈的药物。然而，只有体质强壮者可以使用。如果是虚弱之人，宜使用六君子汤的药材十两，加入贝母二两，共同研成粉末。用竹沥四两、生姜汁一两，混合均匀拌入药粉中。边拌边晾晒，重复九次为止。每次服用三钱，开水送下。因为竹沥和姜汁能够透达痰窠囊袋。虽然对于体内的浊痰进行荡涤是得法的方法，但还必须从潜伏援手之处切断其根株。需要使用各家秘传的诸穴灸法。如果畏惧艾灸的人，适宜在夏季三伏天中，使用张路玉的外贴药末。我家传承有哮喘断根神验药散（该方记载于修园新按中）。加入麝香五分，用姜汁调匀涂抹于肺俞、膏肓、百劳等穴位。涂抹后出现麻木昏沉和疼痛，切勿立即去除，等到三柱香的时间结束，才将其去掉。十日后再次涂抹一次，如此三次，病根即可去除。关于哮喘的辨证施治方法，都详细记载在痰饮、咳嗽、喘促三个门类中，此处不再赘述。
The *Shengji Zonglu* (Comprehensive Mirror of the Holy Relief) refers to this condition as "Xia" (gasping sound). The symptoms include coughing, with excessive phlegm accumulating in the chest and lodging in the throat. As the patient breathes, Qi strikes against the phlegm, producing a gasping or wheezing sound during inhalation and exhalation. Treatment employs Shegan Wan (Belamcanda Pill). The formula consists of Belamcandae Rhizoma (Shegan), Pinelliae Tuberum (Banxia), Citri Reticulatae Pericarpium (Chenpi), Stemona Radix (Baibu), Farfarae Flos (Kuandonghua), Asari Radix et Rhizoma (Xixin), dried old ginger (Gan Laojiang), Schisandrae Fructus (Wuweizi), Fritillariae Bulbus (Beimu), Poria (Fuling), and Prunus Li Ren (Yuziren), each one tael; and Gleditsiae Fructus (Zaojiao), scraped of skin and seeds and roasted, five qian. These are ground into powder together, mixed with honey to form pills the size of tung tree seeds. Taken on an empty stomach with rice water, thirty pills per dose, twice daily.
A floating and slippery pulse is favorable. A short, choppy, intermittent, or scattered pulse is contraindicated.
In my opinion: Asthma (Xiao Chuan) is caused by cold pathogen lurking at Feishu (BL13), while phlegm nests accumulate in the lung membrane. Internal and external factors correspond to each other. Once injured by the six qi (wind, cold, summer-heat, dampness, dryness, fire), the disease manifests. It also manifests due to alcohol injury or food stagnation, anger and qi stagnation, physical overexertion, or sexual exhaustion. Upon manifestation, the cold qi at Feishu and turbid phlegm at the lung membrane conspire to obstruct the airways, preventing respiration. The righteous Qi of respiration then stirs the phlegm, producing snoring or wheezing sounds. This cannot be treated with ordinary medicines. Therefore, the *Shengji Zonglu* uses the aforementioned potent formula. However, it is only suitable for those with strong constitutions. For individuals with weak constitutions, it is advisable to use ten taels of Liu Junzi Tang (Six Gentlemen Decoction) ingredients, plus two taels of Fritillariae Bulbus (Beimu), ground together into powder. Mix evenly with four liang of Zhuli (Bamboo Sap) and one liang of Shengjiangzhi (Fresh Ginger Juice). Stir and sun-dry repeatedly until nine cycles are completed. Take three qian per dose, washed down with boiled water. This is because Bamboo Sap and Fresh Ginger Juice can penetrate the phlegm nests. Although purging internal turbid phlegm is a correct method, one must also cut off the root cause where it lurks and finds support. One must employ various secret acupoint moxibustion methods from different schools. If one fears moxibustion, it is appropriate to use Zhang Luyu's external paste powder during the Sanfu days (the hottest period of summer) in midsummer. My family has a hereditary miraculous powder for curing asthma at its root (the formula is recorded in Xiuyuan Xin'an). Add five fen of Moschus (Shexiang), mix with ginger juice, and apply as a plaster to acupoints such as Feishu (BL13), Gaohuang (BL43), and Bailao (EX-B1). After application, numbness, dizziness, and pain may occur; do not remove it immediately. Wait until three incense sticks have burned out before removing it. Apply once again after ten days. Repeat this three times, and the root of the disease will be eliminated. The differentiation and treatment of asthma are detailed in the sections on Phlegm-Fluids, Cough, and Panting, so no further elaboration is needed here.
