[General Principle] Zhang Zhongjing stated: In Taiyang disease, after more than ten days have passed since the onset (or transmission), there is a sensation of nausea in the epigastrium, accompanied by chest pain. The stool is conversely loose, with slight abdominal fullness, and a feeling of depression and mild irritability. If emetic or purgative treatments were forcibly applied prior to this stage, Tiaowei Chengqi Tang (Stomach-Regulating Decoction) should be administered.
[Commentary] Zhu Gong stated: Vomiting presents as either cold or heat syndromes. If the Cun position pulse is rapid, the palms are hot, and there is irritability, thirst, and vomiting, this indicates heat in the stomach region; Wuling San (Five-Ingredient Poria Powder) is the primary formula.
In Shanghan disease, if exterior symptoms exist, and the patient desires water but vomits immediately upon ingestion, this is termed "Water Reversal" (Shui Ni). It results from heat in the Heart meridian causing dysfunction of the Small Intestine. Wuling San is appropriate. After sweating therapy, if even liquids cannot be retained, it is termed "Reversal." If sweating is applied again, incessant vomiting and diarrhea will ensue. Xiaobanxia Jia Fuling Tang (Minor Pinellia Decoction plus Poria) or Dabanxia Jia Chupi Tang (Major Pinellia Decoction plus Tangerine Peel) may be used.
Ke Qin stated: After more than ten days, the pathogen is no longer in the Taiyang meridian. Referring to it still as "Taiyang disease" indicates a "Huabing" (complicated disease due to mismanagement) of Taiyang. "Xin Xia" refers to the gastric opening. The sensation of nausea in the epigastrium indicates residual heat at the gastric opening and disharmony of Stomach Qi. Therefore, this decoction (Tiaowei Chengqi Tang) is used to gently harmonize the Stomach.
[General Principle] Zhang Zhongjing stated: In Shanghan disease, if coughing and rebellious Qi occur alongside a scattered pulse, the prognosis is fatal.
[Commentary] Zhang Yuansu stated: Ke Ni (hiccup/rebellious Qi) occurs when fire-heat rushes upward urgently, preventing Lung Yin from being contained internally. If constipation is present, Dachengqi Tang (Major Order the Qi Decoction) is indicated; if the stool is soft, Xiexin Tang (Drain the Epigastrium Decoction) is indicated.
Wang Haogu stated: In Shanghan disease, hiccup accompanied by a scattered pulse leads to death; Zhang Zhongjing's words are not false. Generally, this arises from failure to purge earlier. During hiccup, Yin fails to remain internal. Soft stools suit Xiexin Tang; hard stools particularly suit Dachengqi Tang. Who authored these effective remedies? Li Dongyuan (Jiegu) considered them excellent prescriptions.
Hiccup in Shaoyin disease also stems from failure to purge. Yin fluids are nearly exhausted, Yang rebels upward, preventing Yin from remaining internal. However, once Yin is exhausted, Yang will also soon exhaust. Thus, for conditions where Yang is extreme and the pulse is faint and near exhaustion, Xiexin Tang is suitable. If Xiexin Tang is not used, Liangge San (Cool the Chest Powder) without Mangxiao (Natrii Sulfas) and Huanglian (Coptidis Rhizoma) or Qingfei San (Lung-Clearing Powder) may be used. If the pulse is floating on the left and sunken on the right, it is not actually an exterior syndrome. Extreme interior excess can manifest superficially. Why? Hiccup with tongue stiffness and a solid Right pulse indicates Shaoyin interior syndrome. Excessive drinking leading to epigastric stuffiness and hiccup is treated with Wuling San, provided no other ominous signs exist. If ominous signs arise, such as tongue contraction, abnormal speech, dizziness, or sore throat, it belongs to critical Shaoyin syndrome; rapid purging is required, and Dachengqi Tang is suitable. Why is a floating pulse considered exterior? If the pulse is large and solid on superficial palpation but diminished on deep palpation, it is exterior. If it is large and solid on both superficial and deep palpation, it is not exterior. The pathogen has entered deeply. Internal heat should sink; if it floats instead, it indicates Yang extremity returning to the exterior.
Wang Kentang stated: Yin syndrome involves latent Yin cold within. Excessive Yin allows Kidney Water to dominate, Liver Qi fails to generate, Stomach Fire is diseased, and Ding Fire (Heart Fire) diminishes. Thus, Ministerial Fire wanders, and cold pathogen forces accumulation in the chest. This also signifies the exhaustion of Yang. Hence, fever, intense thirst, and a subjective feeling of heat occur, yet others feel coldness in the patient's muscles, bones, marrow, and vessels upon touch. This is "Rootless Fire." Therefore, warming herbs like Dingxiang (Caryophylli Flos) and Ganjiang (Zingiberis Rhizoma) are used to warm the Stomach, causing the fire to descend.
Wu Shou stated: Ke Ni refers to Qi rebelling upward, causing hiccups (Chi Te). Some medical texts mistakenly identify this as coughing. The mention of "death" in this context refers to severe physical depletion. Hiccups can result from Stomach excess due to failure to purge; the Qi rises from the Stomach through the chest and throat. Zhang Yuansu's treatment principle: For failure to purge resulting in internal Stomach heat and excess, with hard stools, use Chengqi Tang; with soft stools, use Xiexin Tang. For Stomach deficiency with heat, use Chupi Zhuru Tang (Tangerine Peel and Bamboo Shave Decoction); for phlegm-fluids, use Banxia Shengjiang Tang (Pinellia and Fresh Ginger Decoction) or Fuling Banxia Tang (Poria and Pinellia Decoction). For Stomach cold, use Chupi Ganjiang Tang (Tangerine Peel and Dried Ginger Decoction) or Jiawei Lizhong Tang (Modified Center-Regulating Decoction). *Jingui Yaolue* states: Qi rushing straight from below the navel to the chest and throat causing hiccups indicates Yin syndrome. The pathology is not in the Stomach but in lower deficiency with latent Yin, or caused by erroneous use of cold medicines leading to extreme cold below, forcing Ministerial Fire upward to accumulate in the chest, signifying Yang exhaustion. Failure to recognize this, and mistaking "water extreme resembling fire" (true cold/false heat) for heat, using cooling medicines will cause immediate collapse. Treatment requires Qianghuo Fuzi San (Notopterygium and Aconite Powder) or Jiawei Fuzi Tang (Modified Aconite Decoction) to urgently warm the lower Jiao. Once True Yang returns, the fire descends, and hiccups stop. For persistent hiccups due to extreme cold, methods involving Liuhuang Xurong San (Sulfur and Frankincense Powder) or moxibustion at Qimen, Zhongwan, Guanyuan, and Qihai acupoints may be used. The goal is to restore warmth to the limbs and regenerate the pulse; when Yang returns and Yin retreats, survival is possible.
Tao Hua stated: Ke Ni is commonly known as hiccups. It stops abruptly after sound emerges from the throat, producing continuous short sounds ("chi chi"), but they are short and not prolonged. Ancients incorrectly equated this with Yue (dry heaving/severe hiccup). Yue resembles gan ou (dry retching), but its sound is turbid, foul, and long, with sound but no matter expelled. Disease reaching Yue is critical. Generally, Ke Ni is close to Yue, but Ke Ni is merely Qi blockage in the chest failing to descend, whereas Yue emits foul sounds externally. The Classics state: Floating Yang pulse indicates Qi Yi (belching/rebellious Qi). Also: Slippery pulse indicates Yue. These errors stem from physicians wrongly treating deficiency as excess. If Ke Ni presents with a chaotic, scattered pulse, it is difficult to treat and differs from Shanghan cough with rebellious Qi. Confusing hiccups with Yue or cough with rebellious Qi leads to many errors. Clinicians must distinguish them clearly.
