吐证门
Chong Tu (Vomiting due to Parasites): Vomiting caused by parasites may result from Stomach Heat or Stomach Cold. Symptoms include changes in the color of vomitus, intermittent abdominal pain, and frequent vomiting of clear saliva. Cold and Heat patterns should be differentiated based on Yin and Yang principles. The Huachong Wan (Parasite-Destroying Pill) with modifications is curative for heat patterns, while the Jiawei Lizhong Tang (Modified Cinnamon Twig and Ginger Decoction) is curative for cold patterns.
[Note]
There are two types of Chong Tu (Vomiting due to Parasites): one caused by the steaming of Heat in the Stomach Meridian, and the other by the forcing of Cold in the Stomach Meridian. Both conditions can cause parasites to become restless, disturb the Stomach, and induce vomiting. Symptoms include lips that are either red or white, intermittent pain at the epigastrium, and frequent vomiting of clear saliva. Whether it belongs to Cold or Heat must be distinguished through differentiation of Yin and Yang syndromes. For Heat patterns, Huachong Wan (Parasite-Destroying Pill) is the primary prescription; for Cold patterns, Jiawei Lizhong Tang (Modified Cinnamon Twig and Ginger Decoction) is the primary prescription.
(Huachong Wan [Parasite-Destroying Pill]): Yuanqi (Tsooshoi Fructus) 5 qian, Heshi (Nartheci Fructus), Kulian Genpi (Meliae Cortex Radicis), Hufen (Cerussa), Shijunzi Rou (Semen Choerospondii), Binglang (Arecae Semen) each 1 liang, Kufan (Alumen) 2 qian 5 fen. Grind the above into fine powder, form pills using wheat paste, and administer according to the child's age and size.
(Jiawei Lizhong Tang [Modified Cinnamon Twig and Ginger Decoction]): Renshen (Ginseng Radix et Rhizoma), Ganjiang (Zingiberis Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma stir-fried with earth), Chuanjiao (Sichuanensis Zanthoxyli Pericarpium), with one Wumei (Mume Fructus) as an additive. Decoct in water and take orally.
(Verse Formula)
Jiawei Lizhong treats parasitic vomiting due to Cold,
Using Renshen, Ganjiang, and Baizhu.
Chuanjiao and Wumei suppress parasite movement,
After decoction and administration, peace is restored.

Xu Tu (Deficiency Vomiting): This condition often arises from weak Stomach Qi. Symptoms include mental fatigue, tremors of the chin, sleeping with eyes open (exposed eyeballs), spontaneous diarrhea without thirst, and frequent vomiting. Ding Shen Sijun Zi Tang (Dingchen-Added Four Gentlemen Decoction) is most effective.
[Note]
Xu Tu (Deficiency Vomiting) is mostly caused by weak Stomach Qi failing to digest and accept milk and food, leading to this syndrome. Symptoms include mental exhaustion, agitation of the fontanelle/eyes, sleeping with eyes exposed, spontaneous diarrhea without thirst, and frequent vomiting. It should be treated with Ding Shen Sijun Zi Tang (Dingchen-Added Four Gentlemen Decoction).
(Ding Shen Sijun Zi Tang [Dingchen-Added Four Gentlemen Decoction]): Renshen (Ginseng Radix et Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma stir-fried with earth), Fuling (Poria), Zhigancao (Prepared Licorice Root), Dingxiang (Caryophylli Flos), Chenxiang (Aquilariae Lignum Resinatum), with Wei Jiang (Roasted Ginger) as an additive.

Xiao'er Shi Tu (Pediatric Excess Vomiting): Characterized by abdominal distension and fullness, difficulty in urination and defecation, abdominal hardness and pain, thirst with a desire for cool drinks, and vomiting of sour, foul-smelling contents. San Yi Cheng Qi Tang (San-Yi Purging Decoction) yields good results.
[Note]
Shi Tu (Excess Vomiting) occurs when a child who is usually robust experiences occasional food stagnation, leading to chest and abdominal distension, constipation or difficult urination/defecation, abdominal hardness and pain, thirst with a desire for cold drinks, and vomiting of sour, foul-smelling matter. San Yi Cheng Qi Tang (San-Yi Purging Decoction) should be used to purge the accumulation. Once bowel movements and urination normalize, vomiting will cease.
(San Yi Cheng Qi Tang [San-Yi Purging Decoction]): Mangxiao (Natrii Sulfas), Sheng Dahuang (Raw Rheum Radix et Rhizoma), Zhishi (Aurantii Fructus stir-fried with bran), Sheng Gancao (Raw Licorice Root), Houpo (Magnoliae Officinalis Cortex stir-fried with ginger), with Sheng Jiang (Fresh Ginger) as an additive.
