呃逆有因痰阻气滞者，有因血瘀者，有因火郁者，有因胃热失下者，此皆属实。有
因中气大虚者，有因大下胃虚，阴火上冲者，此皆属虚。然戴复庵曰∶热呃惟伤寒有
之，他病暴起，多属寒也。半夏生姜汤最妙。 呃在中焦，谷气不运，其声短小，
得食即发。呃在下焦，真气不足，其声长大，不食亦然。寒热虚实，治法不一，古人
治阴呃，每用桂附、干姜、吴茱萸、丁香、茴香诸辛热药，多有收效者，治阳呃，用橘
红竹茹汤。《玉机微义》曰∶呃逆本由阴气已虚，阳火暴甚，直冲而上，出于胃，入于
肺，而作声。东垣用凉药者，所以泻热降火也。若阴症呃逆，以阴气先消，阳火亦竭，
浮于胸中，亦欲散也。故不用寒药，而反用温药养胃，留其阳气胃气一和，阳生则阴长
也。大凡咳逆，脉散者不治。产后呃逆，此恶症也。急灸男左女右期门穴，极效，期门
穴在乳下黑尽一指处是也。

医书中有的写作“逆”，有的写作“哕气”（呃逆的古称）。
呃逆（打嗝）有因痰湿阻滞、气机不畅引起的，有因血瘀引起的，有因火邪郁结引起的，有因胃热未及时通下引起的，这些都属于实证。有因中气严重虚弱引起的，有因过度泻下导致胃虚、阴火上冲引起的，这些都属于虚证。然而戴复庵说：热性呃逆只有伤寒病中有，其他疾病突然发作的，多属于寒证。半夏生姜汤效果最好。呃逆发生在中焦，谷气运行不畅，声音短小，进食后立即引发。呃逆发生在于下焦，真气不足，声音洪亮，即使不进食也会发生。寒证、热证、虚证、实证的治法各不相同，古人治疗阴证呃逆，常用桂枝、附子、干姜、吴茱萸、茴香等辛热药物，大多有效；治疗阳证呃逆，使用橘红竹茹汤。《玉机微义》说：呃逆本是由于阴气已虚，阳火突然亢盛，直冲而上，出于胃，进入肺，从而发出声音。李东垣使用凉药，是为了泻热降火。如果是阴症呃逆，因为阴气先消耗，阳火也枯竭，浮于胸中，想要消散。所以不用寒药，反而用温药养胃，使阳气胃气和顺，阳气生发则阴气也能增长。大凡咳逆，脉象散乱的无法医治。产后呃逆，这是恶症。急灸男性左侧、女性右侧的期门穴，效果极佳，期门穴位于乳头下方黑色毛发尽头一指宽的地方。

Medical texts sometimes write "Ni" (reverse flow), sometimes "Yue Qi" (ancient term for hiccups).
Hiccups (E Ni, 呃逆) may be caused by phlegm obstruction and qi stagnation, blood stasis, fire constraint, or gastric heat failing to be purged; these all belong to excess patterns. They may also be caused by severe deficiency of middle qi, or excessive purging leading to stomach deficiency with yin fire rushing upward; these all belong to deficiency patterns. However, Dai Fu'an stated: Heat-type hiccups occur only in Shanghan (Cold Damage); sudden onset in other diseases mostly belongs to cold patterns. Banxia Shengjiang Tang (Pinellia and Fresh Ginger Decoction) is most effective. Hiccups originating in the Middle Jiao involve impaired transport of grain qi, producing short sounds, triggered immediately after eating. Hiccups originating in the Lower Jiao involve insufficiency of true qi, producing loud sounds, occurring even without eating. The treatment methods differ for cold, heat, deficiency, and excess patterns. In ancient times, treating Yin-pattern hiccups often involved using acrid-hot herbs such as Cinnamon Twig (Guizhi, 桂枝), Aconite Root (Fuzi, 附子), Dried Ginger (Ganjiang, 干姜), Evodiae Fructus (Wuzhuyu, 吴茱萸), and Fennel Seed (Huixiang, 茴香), which were often effective. Treating Yang-pattern hiccups used Juhong Zhuru Tang (Tangerine Peel and Bamboo Shaving Decoction). *Yuji Wei Yi* states: Hiccups originate from deficient yin qi and sudden hyperactivity of yang fire, rushing straight upward, emerging from the stomach, entering the lungs, and producing sound. Li Dongyuan used cooling herbs to purge heat and descend fire. If it is Yin-pattern hiccups, since yin qi is consumed first and yang fire is also exhausted, floating in the chest, it desires to dissipate. Therefore, cold herbs are not used; instead, warm herbs are used to nourish the stomach, harmonizing yang and stomach qi. When yang generates, yin grows. Generally, if coughing/hiccupping presents with a scattered pulse, it is untreatable. Postpartum hiccups are a malignant condition. Immediately moxa the Qimen point on the left side for males and right side for females, which is extremely effective. The Qimen point is located one finger-width below the nipple at the edge of black hair.
