Chai Hu Da Yuan Yin柴胡达原饮
Bupleurum Drink to Reach the Membrane Source
Ingredients10 herbs
Indications
Phlegm-damp obstructing the membrane source. The pathogen is the same lodged, half-in half-out kind that Da Yuan Yin addresses, but the dominant quality is turbid phlegm-damp blocking the qi dynamic rather than pestilential heat consuming fluids.
Clinical Manifestations
- Stuffiness and fullness of the chest and diaphragm in a damp febrile illness
- Malarial fever recurring every other day
- Dizziness with a greasy, unpleasant taste in the mouth
- Cough with phlegm that will not come up
- Thick powdery tongue coat that feels rough to the touch
Health Categories
Modern Applications
Common adjustments
- Heat clearly generated by the constraint — increase Huang Qin 黄芩 and add Zhi Zi 栀子
- Phlegm thick and hard to expectorate — add Zhu Ru 竹茹 and Chuan Bei Mu 川贝母
- Damp obstruction with nausea and poor appetite — add Huo Xiang 藿香 and Bai Dou Kou 白豆蔻
Contraindications
Not for febrile illness with a dry, peeled or coatless tongue, and not once heat has entered the nutritive or blood level. The aromatic, drying and qi-moving herbs consume fluids, so avoid where yin is already damaged.
For licensed practitioners’ reference only — not a self-treatment guide.
Pregnancy
Use with caution in pregnancy — Bing Lang, Qing Pi and Zhi Ke break qi strongly downward. Prescribe only under the supervision of a licensed practitioner.
