[Bencao] Yiwei Cangzhu Wan (Single-Ingredient Atractylodis Rhizoma Pill): Treats vomiting of clear fluid with miraculous effect. (Formula see "Vomiting Acid and Dampness" section.)
[Zhang Zhongjing] Fuling Yin (Poria Decoction): Treats retention of phlegm-fluid and old water in the chest and heart region. After the patient vomits out this fluid, the chest feels empty, Qi is full/stagnant, and food cannot be consumed. This formula eliminates phlegm-Qi and restores appetite.
Ingredients: Fuling (Poria), Renshen (Ginseng), Baizhu (Atractylodis Macrocephalae Rhizoma) (each 3 liang), Zhishi (Immature Bitter Orange), Chenpi (Citri Reticulatae Pericarpium) (2 liang), Chenpi (Citri Reticulatae Pericarpium) (5 qian), Shengjiang (Fresh Ginger) (4 liang).
Preparation and Administration: The above six ingredients are boiled in 6 sheng of water until reduced to 1.8 sheng. Divide into three warm doses. Administer at intervals equivalent to a person walking for eight or nine li.
[Zhu Danxi] Brother Sheng's pulses on both hands were numb and wiry; he vomited clear fluid after drinking.
Ingredients: Shenqu (Massa Medicata Fermentata), Cangzhu (Atractylodis Rhizoma), Xiangfu (Cyperi Rhizoma) (each 5 qian), Yiyuan San (Yunnan Powder), Banxia (Pinelliae Rhizoma) (7.5 qian).
Preparation and Administration: Grind into powder, soak in ginger juice, and form pills using steamed wheat cake as binder.
[Zhang Zhongjing] When thirst drives one to drink water, but the water is immediately vomited upon entry, this is named Shuini (Water Reversal). Wuling San (Five-Ingredient Poria Powder) is the primary treatment. (Formula see "Shanghan" section.)
[Zhu Danxi] Shi Bu, aged forty, suffered from intestinal bleeding and abdominal pain due to excessive moxibustion. The pain has now ceased, but he frequently vomits clear fluid and cannot eat. It is appropriate to clear heat from the stomach.
Ingredients: Huangqin (Scutellariae Radix) (5 fen), Chenpi (Citri Reticulatae Pericarpium), Dihuang (Rehmanniae Radix Praeparata) (each 1 qian), Baizhu (Atractylodis Macrocephalae Rhizoma) (1.5 qian), Lianqiao (Forsythiae Fructus) (1.5 qian), Gancao (Glycyrrhizae Radix et Rhizoma), Fuling (Poria) (each 5 fen), Shengjiang (Fresh Ginger) (3 slices).
[Qianjin Fang] Treats intermittent vomiting caused by phlegm-fluid. The root cause is excessive consumption of cold drinks, which weakens Spleen and Stomach Qi, impairing digestion. Food entering the stomach transforms into cold water, leading to continuous vomiting. Chishizhi San (Red Halloysite Powder) is the primary treatment.
Ingredients: Chishizhi (Halloysitum Rubrum) 1 jin, pounded and sifted. Take one cun-bi (square-inch spoonful) per dose. If taken with wine, increase slightly to three cun-bi per dose. Upon completing one jin, vomiting of phlegm-fluid will cease for life, dysentery will not occur, the Five Zang organs will be tonified, and the body will become robust and healthy. There was a case of phlegm-fluid disease unresponsive to other medicines, which was cured by this formula.
Regarding Yunqi (Six Qi and Five Movements theory), vomiting of clear fluid arises from two patterns:
First, Dampness. The Classic states: "When Taiyin undergoes reversal [of pathogenic influence], there is vomiting, muteness, and spitting of clear fluid; treat with sweet-hot substances." This refers to the aforementioned condition.
Second, Cold. The Classic states: "All pathological fluids that are clear, transparent, and cold belong to Cold." This refers to the aforementioned condition.
