即生姜泻心汤去人参、生姜，加甘草一两。
甘草（四两，炙） 黄芩 干姜（各三两） 半夏（半升，洗） 黄连（一两） 大枣（十二枚，擘） 上六味，
以水一斗，煮取六升，去渣，再煎取三升，温服一升，日三服。
伤寒中风，医反下之，其人下利日数十行，谷不化，腹中雷鸣，心下痞硬而满，干呕，心烦不得安，
医见心下痞，谓病不尽，复下之，其痞益甚，此非结热，但以胃中虚。两次误下，故用甘草以补胃，而
痞自除，俗医以甘草满中，为痞呕禁用之药，盖不知虚实之义者也。客气上逆，故使硬也，甘草泻心汤主之。
翻胃以此加减治之。
半夏（半升，洗） 黄芩 干姜 甘草（炙） 人参（各三两） 黄连（一两） 大枣（十二枚，擘） 上七味，
以水一斗，煮取六升，去渣，再煎，取三升，温服一升，日三服。
伤寒五、六日，呕而发热者，柴胡汤证具，而以他药下之，柴胡证仍在者，复与柴胡汤。此虽已下
之，不为逆，必蒸蒸而振，却发热汗出而解。本症仍在，则即用本方治之。若心下满，而不痛者；此为
痞。又指不痛二字，痞症尤的。柴胡不中与之，宜半夏泻心汤。以上三泻心之药，大半皆本于柴胡汤，故
其所治之症，多与柴胡症相同，而加治虚治痞之药耳。
This is Shengjiang Xiexin Decoction (Ginger Bitter-Heart Decoction) with Ren Shen (Codonopsis Root) and Sheng Jiang (Fresh Ginger Rhizome) removed, and Gan Cao (Licorice Root) added in the amount of one liang.
Gan Cao (4 liang, honey-fried), Huang Qin (Scutellaria Root), Gan Jiang (Dried Ginger Rhizome) (each 3 liang), Ban Xia (Pinellia Tuber) (half sheng, washed), Huang Lian (Coptis Rhizome) (1 liang), Da Zao (Jujube Fruit) (12 pieces, split). The above six herbs,
Boiled in ten dou of water to obtain six sheng of decoction, filter out the dregs, then boil again to obtain three sheng. Take one sheng warm, three times a day.
In cases of Shanghan (Cold Damage) or Zhongfeng (Wind Strike), if the physician erroneously applies purgation, the patient may suffer from diarrhea dozens of times a day, undigested food, borborygmus (rumbling in the abdomen), epigastric fullness and hardness, dry heaving, and irritability with inability to find peace.
If the physician sees the epigastric fullness and assumes the pathogen remains, applying purgation again will exacerbate the fullness. This is not due to accumulated heat, but rather deficiency in the Stomach. Due to two erroneous purgations, Gan Cao (Licorice Root) is used to tonify the Stomach Qi, thereby resolving the fullness naturally. Empirical physicians consider Gan Cao (Licorice Root) as obstructing the middle jiao and thus contraindicated for fullness and vomiting; this stems from a lack of understanding regarding the principles of excess and deficiency. When rebellious Qi ascends, it causes hardness; Gancao Xiexin Decoction (Licorice Bitter-Heart Decoction) should be administered.
Fanwei (Regurgitation/Reverse Vomiting) can be treated by modifying this formula.
Ban Xia (Pinellia Tuber) (half sheng, washed), Huang Qin (Scutellaria Root), Gan Jiang (Dried Ginger Rhizome), Gan Cao (Licorice Root) (honey-fried), Ren Shen (Codonopsis Root) (each 3 liang), Huang Lian (Coptis Rhizome) (1 liang), Da Zao (Jujube Fruit) (12 pieces, split). The above seven herbs,
Boiled in ten dou of water to obtain six sheng of decoction, filter out the dregs, then boil again to obtain three sheng. Take one sheng warm, three times a day.
After five or six days of Shanghan (Cold Damage), if there is vomiting accompanied by fever, the Zheng (syndrome) of Chaihu Tang (Bupleurum Decoction) is present. If other drugs were erroneously used for purgation, and the Zheng (syndrome) of Chaihu Tang (Bupleurum Decoction) persists, administer Chaihu Tang (Bupleurum Decoction) again. Although purgation has been applied, it does not constitute a complication (Ni). The patient will inevitably experience shaking and chills, followed by fever and sweating, leading to resolution. If the original symptoms persist, use the original formula immediately. If there is epigastric fullness without pain, this is termed Pi (Glomus/Fullness). The emphasis on "without pain" precisely defines the Pi syndrome. In this case, Chaihu Tang (Bupleurum Decoction) is not indicated; Banxia Xiexin Decoction (Pinellia Bitter-Heart Decoction) is appropriate. The herbs in the above three Xiexin Decoctions are largely derived from Chaihu Tang (Bupleurum Decoction); therefore, the syndromes they treat are mostly similar to those of Chaihu Tang (Bupleurum Decoction), with the addition of herbs that address deficiency and resolve Pi (Glomus/Fullness).
