【内火喘逆的症状】五心烦热（手心、脚心及心胸烦热），口干舌燥，嘴唇干裂焦枯，气喘急促并伴有自汗，进食后症状稍减轻，但过一会儿又复发，发作有时停止有时出现，面色发红，大便秘结，这是由内火引起的喘逆病症。
【内火喘逆的原因】内在方面是欲望妄动，外在方面是起居生活受到惊吓，导致五脏情志所化的厥阳之火，时常在体内躁动，煎熬消耗真阴，致使精液枯竭、血液干燥，内火克制肺金，使肺气焦灼胀满，从而引发喘逆。
【内火喘逆的脉象】脉象多表现为洪大且数（快），这是心火上炎的表现。左关脉数，表示肝胆有热。两尺脉洪数，表示肾火上逆。右寸脉数，表示肺中有火。右关脉洪数，表示胃家有热。
【内火喘逆的治疗】若是肾虚火旺，应当滋养阴液以制约火邪，通过壮水之主（滋补肾阴）来抑制阳光（虚火），可用门冬饮子、家秘肝肾丸。若是肝火上冲，宜用柴胡清肝散。若是心火上炎，宜用导赤各半汤。若是脾胃之火上冲，宜用清胃汤。若是肺火煎熬，宜用石门冬饮子（详见伤燥嗽门）。
家秘肝肾丸：治疗肾水不足，虚火上炎。
药材：黄柏、知母、白芍药、当归。
将这四味药研成末，再用天冬、地黄两味药同煎，收膏制成丸剂。

导赤各半汤：详见前文心咳部分。

药材：桑白皮、地骨皮、桔梗、甘草、石膏。
【痰饮喘逆的症状】面色苍白无华，胸中漉漉有声（如水流动的声音），时而咳嗽时而呕吐，平卧时喘逆加重，这是痰饮引起的喘逆病症。
【痰饮喘逆的原因】饮水过多，脾脏虚弱不能正常输布水液，水湿积聚在肠间，形成痰和饮，向上干扰肺脏，从而导致喘息。
【痰饮喘逆的脉象】多见弦滑脉，或见弦紧脉，或见弦数脉。弦紧脉主寒饮，弦数脉主痰热。
【痰饮喘逆的治疗】可用苓桂术甘汤、小半夏汤、甘遂半夏汤、二陈汤。若兼有表证者，用小青龙汤；大便闭塞者，用导痰汤加大黄，病情严重者用滚痰丸、十枣汤。

[Symptoms of Panting and Reversal due to Internal Fire] Five-center heat distress (heat sensation in the palms, soles, and chest), dry mouth and parched lips, panting and reversal with spontaneous sweating. Symptoms decrease slightly after eating but recur shortly thereafter; they come and go intermittently. The face is red, and there is constipation. This is a case of panting caused by internal fire.
[Causes of Panting and Reversal due to Internal Fire] Internally, excessive desire moves recklessly; externally, daily life is disrupted by fright. The Jue-Yang fire generated from the five emotional zang organs stirs within at times, simmering and consuming the true yin. Essence becomes exhausted, and blood dries up. Internal fire attacks Metal (the Lung), causing the Lung Qi to become scorched and distended, leading to panting and reversal.
[Pulse of Panting and Reversal due to Internal Fire] The pulse is mostly surging (Hong) and rapid (Shu), indicating Heart Fire flaring upward. A rapid pulse at the left Guan position indicates Heat in the Liver and Gallbladder. Surging and rapid pulses at both Chi positions indicate Kidney Fire reversing upward. A rapid pulse at the right Cun position indicates Fire in the Lung. A surging and rapid pulse at the right Guan position indicates Heat in the Stomach.
[Treatment of Panting and Reversal due to Internal Fire] If it is Kidney Deficiency with vigorous Fire, one should nourish Yin to control Fire, strengthen the source of Water (nourish Kidney Yin) to suppress the Yang (deficient fire). Use Men Dong Yin Zi (Asparagus Decoction) or Jia Mi Gan Shen Wan (Secret Formula for Nourishing Liver and Kidney Pills). If Liver Fire rushes upward, use Chai Hu Qing Gan San (Bupleurum Powder to Clear the Liver). If Heart Fire flares upward, use Dao Chi Ge Ban Tang (Half-Portion Decoction to Guide Out Redness). If Spleen and Stomach Fire rushes upward, use Qing Wei Tang (Stomach-Clearing Decoction). If Lung Fire causes simmering, use Shi Men Dong Yin Zi (see the section on Cough due to Dryness).
Jia Mi Gan Shen Wan: Treats insufficiency of Kidney Water with deficient Fire flaring upward.
Herbs: Huang Bo (Phellodendri Cortex), Zhi Mu (Anemarrhenae Rhizoma), Bai Shao Yao (Paeoniae Radix Alba), Dang Gui (Angelicae Sinensis Radix).
Grind these four herbs into powder, then decoct Tian Dong (Asparagi Radix) and Di Huang (Rehmanniae Radix) together, reduce to an extract, and form pills.
Chai Hu Qing Gan San:
Herbs: Chai Hu (Bupleuri Radix), Huang Qin (Scutellariae Radix), Ren Shen (Ginseng Radix), Shan Zhi (Gardeniae Fructus), Lian Qiao (Forsythiae Fructus), Jie Geng (Platycodonis Radix), Gan Cao (Glycyrrhizae Radix et Rhizoma).
Dao Chi Ge Ban Tang: See the previous section on Heart Cough.
Shi Gao Xie Bai San:
Herbs: Sang Bai Pi (Mori Cortex), Di Gu Pi (Lycii Cortex), Jie Geng (Platycodonis Radix), Gan Cao (Glycyrrhizae Radix et Rhizoma), Shi Gao (Gypsum Fibrosum).
[Symptoms of Panting and Reversal due to Phlegm-Fluid Retention] The complexion is pale and empty. There is a gurgling sound in the chest. There is intermittent coughing and vomiting. Panting and reversal worsen when lying down. This is a case of panting caused by Phlegm-Fluid retention.
[Causes of Panting and Reversal due to Phlegm-Fluid Retention] Excessive drinking of water, combined with weak Spleen function unable to distribute fluids properly, leads to water accumulation in the intestines, forming Phlegm and Fluid. These rise to interfere with the Lung, resulting in panting.
[Pulse of Panting and Reversal due to Phlegm-Fluid Retention] The pulse is mostly wiry (Xuan) and slippery (Hua), or wiry and tight (Xuan Jin), or wiry and rapid (Xuan Shu). Wiry-tight indicates Cold-Fluid; wiry-rapid indicates Phlegm-Heat.
[Treatment of Panting and Reversal due to Phlegm-Fluid Retention] Use Ling Gui Zhu Gan Tang (Poria, Cinnamon Twig, Atractylodes, and Licorice Decoction), Xiao Ban Xia Tang (Minor Pinellia Decoction), Gan Sui Ban Xia Tang (Kansui and Pinellia Decoction), or Er Chen Tang (Two-Aged Decoction). If accompanied by exterior symptoms, use Xiao Qing Long Tang (Minor Green Dragon Decoction); if there is fecal impaction, use Dao Tan Tang (Phlegm-Guiding Decoction) with added Da Huang (Rhei Radix et Rhizoma); in severe cases, use Gun Tan Wan (Rolling Phlegm Pill) or Shi Zao Tang (Ten Dates Decoction).
