半夏（一升。） 生姜（半斤。） 茯苓（四两。）
上三味。以水七升。煮取一升五合。分温再服。
歌曰 呕吐悸眩痞又呈。四苓升夏八姜烹。膈间有水金针度。澹渗而辛得病情。
男元犀按。水滞于心下则为痞。水凌于心则眩悸。水阻胸膈则阴阳升降之机不利为呕吐。
方用半夏降逆。生姜利气。茯苓导水。合之为涤痰定呕之良方。
（此证见之于肺痈。）支饮导致呼吸急促困难。此证用葶苈大枣泻肺汤主治。
徐大椿按：肺主气，是气机出入的通道。张仲景说，支饮导致呼吸急促困难的，是因为水饮邪气壅塞于肺，填塞了气道。方中用葶苈子泄……
治疗呕吐患者本应口渴，如果口渴说明病将要解除。现在反而不渴，是因为心下有支饮停留的缘故。此汤剂主治此证。
半夏（一升） 生姜（半斤）
以上两味药，用水七升，煮取一升半，分两次温服。
歌诀云：呕吐患者若见口渴，饮水当能祛除水饮。（因为水饮随呕吐而去，故感到口渴。）若不渴，应当知道是支饮停聚。（因为水饮能制约燥热，如今因不渴，可知心下……）
徐大椿按：《神农本草经》记载半夏的功效很大，张仲景的各个方剂中，无不遵循其法使用。凡是呕吐者，必定加入此味药。

半夏（一升） 生姜（半斤） 茯苓（四两）
以上三味药，用水七升，煮取一升五合，分两次温服。
歌诀云：呕吐、心悸、眩晕、痞塞症状又呈现。用四苓、半夏、八两生姜烹制。膈间有水气需金针度穴（指治法精妙），淡渗利湿兼辛散得病情之真意。
徐大椿按：水气停滞于心下则为痞塞，水气凌犯于心则致眩晕心悸，水气阻于胸膈则使阴阳升降之机不利而导致呕吐。方中用半夏降逆气，生姜利气机，茯苓导水湿，合起来成为涤痰定呕的良好方剂。
(See Lung Abscess.) Wheezing and dyspnea due to fluid retention in the chest (Zhi Yin). This is treated with Tingli Dazao Xiefei Decoction.
Xu Dachun comments: The Lung governs Qi and serves as the pathway for its entry and exit. Master Zhang Zhongjing stated that wheezing and dyspnea caused by Zhi Yin result from pathogenic fluid obstructing the Lung, blocking the Qi pathways. The formula uses Tinglizi to drain...
In patients who vomit, thirst is expected; if they are thirsty, it indicates the condition is resolving. If they are not thirsty now, it is because fluid retention (Zhi Yin) exists below the heart. This decoction treats this condition.
Banxia (1 sheng) Shengjiang (0.5 jin)
Take the above two ingredients, add seven sheng of water, boil to obtain one and a half sheng, and divide into two warm doses.
Song says: When a vomiting patient becomes thirsty, drinking should remove the fluid. (Fluid is expelled with vomit, hence thirst.) If not thirsty, know that Zhi Yin resides. (Fluid can restrain dryness; now, due to lack of thirst...)
Xu Dachun comments: The *Shennong Bencao Jing* records great efficacy for Banxia. In all formulas of Zhang Zhongjing, its use follows these principles. For any vomiting case, this herb must be added.
Vinegar-soaked
Sliced
Ginger juice

Draining fluid
Treat abdominal fullness and dry mouth and tongue, indicating water qi between the intestines. This formula treats it.
Fangji Jiumu Tingli Dahuang (each 1 liang)
Grind the above four herbs into powder, mix with honey to make pills the size of wutong seeds. Take before meals, one pill per dose, three times daily. Gradually increase the dose. If saliva appears in the mouth and thirst occurs, add Mangxiao half...
Song says: Water in the intestines leads to dry lips. (Since fluid gathers below, it no longer moistens the upper part; later, even if fluid enters, it tends downward and cannot nourish...)
Cheng said: Fangji and Jiumu guide fluid out anteriorly, while Dahuang and Tingli push fluid out posteriorly. Anterior and posterior dispersion reduces abdominal fullness and moves fluid. Spleen Qi...
Treat sudden vomiting, epigastric stuffiness (Pi), intercostal fluid retention, dizziness, and palpitations. This formula treats it.
Banxia (1 sheng) Shengjiang (0.5 jin) Fuling (4 liang)
Take the above three ingredients, add seven sheng of water, boil to obtain one and five tenths sheng, and divide into two warm doses.
Song says: Vomiting, palpitations, dizziness, and stuffiness present again. Cook Siling, Banxia, and eight liang of Shengjiang. Intercostal fluid requires the golden needle technique; mild diuresis combined with acrid dispersal captures the disease's nature.
Xu Dachun comments: Fluid stagnating below the heart causes Pi; fluid overwhelming the heart causes dizziness and palpitations; fluid obstructing the thoracic diaphragm impedes the ascending and descending mechanism of Yin and Yang, leading to vomiting. The formula uses Banxia to direct rebellious Qi downward, Shengjiang to promote Qi movement, and Fuling to guide out water. Together, they form an excellent formula for draining phlegm and stopping vomiting.
