伤寒病出现干呕症状，是指有想呕吐的感觉但吐不出东西。这通常是因为邪热停留在胃中，或者在发汗解表之后，胃气不和，体内仍有蓄积的热气，热气熏蒸上焦，导致心下（胃脘部）痞塞结聚，从而引起干呕。况且各种邪气侵犯胃部，导致胃气上逆，都会引发呕吐。如果是寒邪引起的，则是寒痰凝滞，呕吐出涎沫，这样会消耗津液；只有那种单纯因气机上逆而没有实物可吐的情况，才称为干呕。治疗时必须仔细辨别，不可不察。
歌诀说：呕吐但没有吐出物叫做干呕；伴有腹泻的三种情况属于少阴病。伴有胁痛、头痛以及水气病的，其中自有懂得的人来辨析。
少阴病下利的三种证候：如果腹泻不止，呕吐逆乱且摸不到脉搏，或者干呕伴心烦的，用白通加猪胆汁汤治疗；如果脉象微弱的，用白通汤治疗；如果里寒外热，脉象微弱甚至摸不到，或者有干呕症状的，用通脉四逆汤治疗。如果干呕并吐出涎沫，伴有头痛的，用吴茱萸汤治疗。服用上述药物后病情加剧或复杂的，用小柴胡汤治疗。如果出汗、头痛、干呕的，用桂枝汤治疗。如果心下有停饮，干呕且发热的，属于表证，用小青龙汤治疗。如果身体凉爽且出汗，两胁疼痛，干呕且呼吸短促，心内痞塞且咳嗽，轻微腹泻，且不恶寒的，这是表证已解，里有水饮，应用十枣汤攻下。如果膈上有寒饮导致干呕的，可以用温法治疗，如四逆汤。如果干呕且伴有腹泻的，用黄芩半夏生姜汤治疗。大抵而言，热邪在胃脘，与谷气相搏，热气上熏，导致心下痞塞结聚，就会发生呕吐但无物可吐的情况，这属于少阴下利范畴，姜附类药物主治下利。厥阴病吐涎沫，由吴茱萸汤主治。出汗且干呕，由桂枝汤主治自汗。邪气去除后，呕吐自然停止。
至于水气导致的两种证候，应当根据病位在表或在里来区分。如果发热、咳嗽气喘且干呕的，这是水气在表，给予小青龙汤。如果不发热、不恶寒，伴有胁痛、咳嗽腹泻且干呕的，这是水气在里，给予十枣汤。这也是必须加以区分的。然而，表证的水气都伴有咳嗽，为什么呢？回答说：这是因为水气侵犯肺脏所致。

Dry retching in cold damage (Shanghan) refers to the sensation of wanting to vomit but nothing is expelled. This is usually caused by pathogenic heat lingering in the stomach, or after sweating therapy has resolved the exterior, leading to disharmony in the stomach and retained heat within. The heat steams upward to the Upper Jiao (Upper Burner), causing stagnation and binding in the epigastrium (Xin Xia), thus inducing dry retching. Furthermore, various pathogens invading the stomach cause rebellious Stomach Qi, resulting in vomiting. If due to cold pathogens, it involves congealed cold phlegm, with expulsion of saliva and foam, which consumes body fluids; only when there is purely rebellious Qi without any substance to expel is it termed "dry retching" (Gan Ou). Treatment requires careful differentiation and cannot be overlooked.
The verse states: Vomiting without substance is called dry retching; diarrhea associated with three types of patterns belongs to Shaoyin disease. Those accompanied by hypochondriac pain, headache, and fluid retention have their own discerning experts.
Regarding the three syndromes of Shaoyin diarrhea: If diarrhea persists, vomiting and rebellious Qi occur with a faint or imperceptible pulse, or if there is dry retching accompanied by vexation, use Baitong Tang plus Pig Gallbladder Bile Decoction (Baitong Jia Zhudanzhi Tang). If the pulse is faint, use Baitong Tang. If there is interior cold with exterior heat, a faint or absent pulse, or dry retching, use Tongmai Sini Tang (Pulse-Reviving Four Reversals Decoction). If there is dry retching with expulsion of saliva/foam and headache, use Wuzhuyu Tang (Evodia Decoction). If symptoms worsen or become complex after taking these, use Xiaochaihu Tang (Minor Bupleurum Decoction). If there is sweating, headache, and dry retching, use Guizhi Tang (Cinnamon Twig Decoction). If there is fluid retention in the epigastrium, dry retching, and fever, this belongs to an Exterior Syndrome; use Xiao Qinglong Tang (Minor Blue Dragon Decoction). If the body is cool with sweating, bilateral hypochondriac pain, dry retching, shortness of breath, epigastric fullness/stuffiness, cough, slight diarrhea, and no aversion to cold, the exterior is resolved, and there is fluid retention inside; use Shizao Tang (Ten Jujube Decoction) to purge. If there is cold-fluid retention above the diaphragm causing dry retching, warm methods can be used, such as Sini Tang (Four Reversals Decoction). If there is dry retching with diarrhea, use Huangqin Banxia Shengjiang Tang (Scutellaria, Pinellia, and Fresh Ginger Decoction). Generally speaking, heat in the stomach cavity combining with food Qi causes heat to steam upward, leading to epigastric stagnation and vomiting without expulsion; this falls under Shaoyin diarrhea, treated with ginger and aconite herbs. For Jueyin disease with expulsion of saliva/foam, Wuzhuyu Tang is indicated. For sweating with dry retching, Guizhi Tang treats spontaneous sweating. Once pathogens are eliminated, vomiting ceases naturally.
As for the two patterns caused by fluid retention, they should be distinguished by whether the pathology is in the Exterior or Interior. If there is fever, cough, wheezing, and dry retching, this indicates fluid retention in the Exterior; administer Xiao Qinglong Tang. If there is no fever, no aversion to cold, hypochondriac pain, cough, diarrhea, and dry retching, this indicates fluid retention in the Interior; administer Shizao Tang. This distinction is essential. However, why do all Exterior water-patterns involve cough? The answer is that fluid retention invades the Lung.
