Chai Hu Jia Long Gu Mu Li Tang
Overview
Chai Hu Jia Long Gu Mu Li Tang originated from Zhang Zhongjing’s Treatise on Cold Damage and is a classic formula for harmonizing the Shao Yang and calming the Spirit with heavy settling substances.
Formula Composition
Modern commonly used versions are centered on Chai Hu, Huang Qin, Ban Xia, Ren Shen, Sheng Jiang, Gui Zhi, Fu Ling, Long Gu, Mu Li, Da Huang, and Da Zao; the ancient formula records also include Qian Dan.
Note: Qian Dan contains lead. Modern regulated preparations generally modify or omit the Qian Dan used in the ancient formula; the actual product labeling must be followed.
Traditional Actions and Indications
Traditionally used for manifestations of Shao Yang disharmony accompanied by phlegm-heat disturbing the Heart, such as chest fullness, agitation with fright, palpitations, insomnia, irritability, and dizziness. In modern Kampo medicine, it is also commonly used for pattern-differentiated treatment of some anxiety, insomnia, or autonomic nervous system-related symptoms.
Precautions
- Do not prepare versions containing Qian Dan according to ancient texts without professional guidance; lead has clearly established toxicity.
- Severe insomnia, agitation, depression, or palpitations with chest pain should first receive professional evaluation.
- The formula contains Da Huang; people with diarrhea, pregnant women, and those with weak constitutions should exercise caution.
- Only select regulated modern preparations and verify the complete ingredient list.
