Effects: Releases the exterior and clears interior heat; raises the clear yang and stops diarrhea.
Core pathomechanism: Exterior pattern not yet resolved, with pathogens sinking into the Yangming, resulting in heat-associated diarrhea. That is, the exterior pathogen from an external contraction has not been fully resolved and sinks internally into the intestines, so that interior heat forms, presenting with fever, diarrhea, and related symptoms.
1. When it is used
The composition of this formula is concise and refined, embodying the method of "rowing against the current to save the boat" (ni liu wan zhou), treating the interior pattern by dispersing and lifting the exterior pathogen.
2. Pattern and presentation (core indicators)
Main symptoms:
Fever with diarrhea: fever accompanied by diarrhea.
Vexing heat in the chest and epigastrium: a sensation of vexation and heat in the chest and stomach region.
Dryness of the mouth with thirst: dryness of the mouth with a desire to drink.
Panting with sweating: rapid breathing with sweating (caused by interior heat forcing the Lung and forcing out fluids).
Tongue and pulse:
o Tongue: red tongue body with yellow, greasy coating.
o Pulse: rapid or hurried pulse.
3. Common modifications
With concurrent vomiting: add Ban Xia (pinellia rhizome), Sheng Jiang (fresh ginger), and Zhu Ru (bamboo shavings) to harmonize the stomach, downbear counterflow, and stop vomiting.
With food stagnation, abdominal pain and distension: add Jiao Shan Zha (charred hawthorn fruit), Shen Qu (medicated leaven), and Mu Xiang (costusroot) to disperse food and resolve stagnation.
With severe abdominal pain: add Bai Shao (white peony root) to soften the Liver and relax spasm to relieve pain.
With dampness heavier than heat, abdominal distension with greasy tongue coating: add Hou Po (magnolia bark), Cang Zhu (atractylodes rhizome), and Che Qian Zi (plantago seed) to move qi, dry dampness, and disinhibit water.
Modern applications: This formula is widely used for acute enteritis, bacillary dysentery, acute flare of ulcerative colitis, rotavirus enteritis in children, and diabetic diarrhea, where these belong to the pattern of interior heat (or damp-heat) diarrhea.
4. Cautions and clinical notes
Contraindications:
o Not to be used in diarrhea due to deficiency cold. This presents with clear, thin, completely undigested stool, cold pain in the abdomen, and a pale tongue with white coating.
o This formula is bitter and cold in nature; discontinue once the condition resolves and do not use it for a prolonged period, so as not to damage the Spleen and Stomach yang qi.
5. Granule conversion and dose
Calculation of the total raw herb weight in the original formula:
o Ge Gen (kudzu root) 15g + Huang Qin (scutellaria root) 9g + Huang Lian (coptis rhizome) 9g + Zhi Gan Cao (prepared licorice root) 6g = 39 grams.
Converted to a 5:1 granule extract:
o 39 grams of raw herb ÷ 5 = 7.8 grams of granules.
Recommended dose:
o One dose per day, dissolved in warm water in 2 portions, about 4 grams per portion.
o Or as directed by a physician; for acute diarrhea, a physician may advise taking 1.5-2 doses per day. Please follow the prescription strictly.
