心下筑筑惕惕，怔怔忡忡，悸病之状也。饮水多而小便少，水停心下，宜茯苓甘草汤，或五苓散。厥冷
为寒，宜真武汤。汗后为虚，宜小建中汤。或不因汗后，是虚之甚也，宜炙甘草汤。
战谓身抖耸动也，栗谓心内发HT 也，振亦耸动，比之于战则无力也。所以论中曰振振者，皆
责其虚也。栗邪气为之也，战正气为之也，邪正相交故争也。此证若生于汗吐下之后，是虚其中外而致逆
也，若不致逆邪，因以衰正，因以和而作解，则为正胜邪却，战栗汗出而平也。
今之名曰呃逆，即古之名曰KT 也。KT 者气噎结有声也，世有以哕为呃逆者，盖不知哕之声，声从胃
里退场门，不似KT 之格格连声，气从脐下来自冲脉，退场门作声也，呃逆颇类嗳气、噫气、嗳气者因饱食太急，
此时作嗳转食气也；噫气者，因过食、伤食越食作噫食臭气也，均属气逆为病。呃逆之病，胃气虚竭也。兼热
者，以橘皮竹茹汤加柿蒂主之。兼大便不利者，以三承气汤主之。兼小便不利者，以五苓散汤主之。兼肾虚
不能摄冲脉之气归原者，以都气汤加牛膝主之。兼寒虚者，在太阴手足温，以吴茱萸、理中汤主之。在少阴手
足厥，更加附子。兼
痞硬下利者，以生姜泻心汤主之。兼痞硬噫气者，以旋复代赭石汤主之。
The sensation of palpitation and fearfulness in the epigastrium (region below the heart) characterizes the disease of Heart Palpitations (Xin Ji). If there is excessive water intake but scanty urination, it indicates Water Retention in the Epigastrium; Fuling Gancao Tang (Poria and Licorice Decoction) or Wuling San (Five-Ingredient Powder with Poria) are appropriate. Limb coldness indicates Cold syndrome; Zhenwu Tang (True Warrior Decoction) is appropriate. Occurrence after sweating indicates Deficiency; Xiaojianzhong Tang (Minor Construct the Middle Decoction) is appropriate. If it occurs not after sweating, it signifies severe Deficiency; Zhigancao Tang (Honey-Baked Licorice Decoction) is appropriate.
"Zhan" refers to bodily trembling and shivering; "Li" refers to inner mental fear and trembling; "Zhen" also denotes shivering, but is weaker than "Zhan". Therefore, the Treatise states that instances of "Zhenzhen" are all attributed to Deficiency. "Li" is caused by pathogenic factors; "Zhan" is caused by healthy Qi. The contention arises from the interaction between pathogenic factors and healthy Qi. If this syndrome occurs after sweating, vomiting, or purging, it results from Deficiency in the interior and exterior leading to rebellious Qi. If the rebellion does not expel the pathogen, but rather the healthy Qi declines, and harmony is restored allowing resolution, then healthy Qi overcomes the pathogen, and the patient recovers through shivering and sweating.
What is now named E'ni (Hiccups) was formerly named Yue (belching with sound). Yue refers to Qi obstruction with audible sounds. Some people equate Yue with E'ni today, likely due to ignorance: the sound of Yue emanates from the stomach and exits through the anus, unlike E'ni which produces a continuous "ge-ge" sound. The Qi of E'ni originates from the Chong Mai (Penetrating Vessel) below the navel and makes sound upon exiting through the anus. E'ni resembles Aqi (belching) and Yi qi (eructation): Aqi occurs due to eating too quickly, releasing food Qi; Yi qi occurs due to overeating, damaged food, or binge eating, releasing foul-smelling food Qi. All belong to diseases of Rebellious Qi. The pathology of E'ni lies in the exhaustion of Stomach Qi. For cases accompanied by Heat, Jupi Zhuru Tang (Tangerine Peel and Bamboo Shavings Decoction) added with Persimmon Calyx (Shidi) is the primary formula. For cases accompanied by constipation, the Three Chengqi Tangs (Three Draining Qi Decoctions) are used. For cases accompanied by dysuria, Wuling San Tang (Five-Ingredient Powder with Poria Decoction) is used. For cases accompanied by Kidney Deficiency failing to control the Qi of the Chong Mai returning to its origin, Duqi Tang added with Achyranthes Root (Niuxi) is used. For cases accompanied by Cold and Deficiency, if presenting in the Taiyin stage with warm hands and feet, Wu Zhu Yu Tang or Lizhong Tang (Regulate the Middle Decoction) is used; if presenting in the Shaoyin stage with cold limbs, Aconite (Fuzi) is added. For cases accompanied by fullness, hardness, and diarrhea, Shengjiang Xiexin Tang (Fresh Ginger Bitter Decoction) is used. For cases accompanied by fullness, hardness, and eructation, Xuanfu Daizhe Shi Tang (Inula and Hematite Decoction) is used.
