秦子曰∶喘者,促促气急,喝喝喘息,甚者张口抬肩,摇身撷肚,与短气不相接续,逆
气上奔而不下者不同。若喘促,喉中如水鸡声,谓之哮。《正传》云∶喘以气息言,哮以声
响名。河间云∶病寒则气衰而息微,病热则气盛而息粗。诸经皆令人喘,而多在肺胃二家,
喘而咳逆嗽痰者,肺也;喘而呕吐者,胃也。今立外感三条,内伤六条。
【风寒喘逆之症】头痛身痛,身发寒热,无汗恶寒,喘咳痰鸣,气盛息粗,此外感风寒
【风寒喘逆之因】外冒风寒,皮毛受邪,郁于肌表,则身热而喘;逆于阳明,则呕吐而
喘;壅于肺家,则咳嗽而喘;肺风痰喘之症也。
【风寒喘逆之脉】浮缓为风,浮紧为寒。六脉俱浮,表有风寒;六脉沉数,寒郁为热。
【风寒喘逆之治】风气胜者,宜散风解表,防风泻白散、防风桔梗汤。寒气胜者,小青
龙汤、三拗汤、麻黄定喘汤。寒郁成热,逆于阳明,呕吐者,干葛竹茹汤、平胃散。

Qin Zi said: The syndrome of panting (Chuan) is characterized by rapid and shortness of breath, audible wheezing, and in severe cases, opening the mouth and raising the shoulders, swaying the body, and retracting the abdomen. This is different from shortness of breath (Duan Qi), which is characterized by shallow breathing that cannot be sustained, with rebellious Qi rushing upward without descending. If panting is accompanied by a sound in the throat resembling that of a water chicken (frog), it is called asthma (Xiao). *Zheng Chuan* states: "Panting refers to the state of breath, while asthma refers to the sound." He Jian (Liu Wansu) stated: "In cold diseases, Qi declines and respiration becomes faint; in heat diseases, Qi is excessive and respiration becomes coarse." Pathologies of all meridians can cause panting, but they mostly occur in the Lung and Stomach organs. Panting accompanied by coughing and expectoration indicates pathology in the Lung; panting accompanied by vomiting indicates pathology in the Stomach. Herein, three categories for exogenous causes and six categories for endogenous injuries are established.
[Symptoms of Wind-Cold Rebellious Panting] Headache, body pain, alternating chills and fever, absence of sweating, aversion to cold, panting with coughing and loud phlegm sounds, excessive Qi and coarse respiration. These are manifestations of exogenous Wind-Cold.
[Etiology of Wind-Cold Rebellious Panting] External invasion by Wind-Cold, where pathogens affect the skin and hair, stagnate in the muscle layer, leading to fever and panting; rebellion against the Yangming Meridian leads to vomiting and panting; congestion in the Lung organ leads to coughing and panting. This is the syndrome of Wind-Phlegm Panting of the Lung.
[Pulse of Wind-Cold Rebellious Panting] A floating and moderate pulse indicates Wind dominance; a floating and tight pulse indicates Cold dominance. All six pulses being floating indicates exogenous Wind-Cold on the exterior; all six pulses being deep and rapid indicate Cold stagnation transforming into Heat.
[Treatment of Wind-Cold Rebellious Panting] For Wind dominance, it is appropriate to disperse Wind and release the exterior, using Fangfeng Xiebai San (Saposhnikovia Decoction to Drain the Lungs) or Fangfeng Jiegeng Tang (Saposhnikovia and Platycodon Decoction). For Cold dominance, use Xiao Qinglong Tang (Minor Green Dragon Decoction), San'ao Tang (Three Unblocking Decoction), or Mahuang Dingchuan Tang (Ephedra Asthma-Calming Decoction). For Cold stagnation transforming into Heat, rebelling against the Yangming Meridian with vomiting, use Gange Zhuru Tang (Kudzu and Bamboo Shavings Decoction) or Pingwei San (Stomach-Pacifying Powder).
Fangfeng Xiebai San See the previous section on Asthma Syndrome.
