1. Origin Background
Chai Ge Jie Ji Tang (柴葛解肌汤), or Bupleurum and Kudzu Decoction to Release the Muscle Layer, is a classical formula from Tao Hua’s Shang Han Liu Shu (Six Books of Cold Damage). It belongs to the category of formulas that release the exterior and clear interior Heat from the muscle layer.
This formula addresses an unresolved Wind-Cold exterior pattern that is transforming into interior Heat, especially in the Yangming muscle layer. Typical signs include increasing fever, decreasing chills, headache, orbital or eye pain, dry nasal passages, irritability, insomnia, a thin yellow tongue coating, and a floating slightly flooding pulse.
Combining Chai Hu and Ge Gen as the chief herbs to release the muscle layer and vent Heat from Shaoyang and Yangming, Qiang Huo and Bai Zhi to dispel residual Wind-Cold from the Taiyang and Yangming channels of the face and head, Shi Gao and Huang Qin to clear interior Heat, Jie Geng to disseminate Lung Qi, Bai Shao to astringe Yin and prevent excessive sweating, and Gan Cao with Sheng Jiang and Da Zao to harmonize, Chai Ge Jie Ji Tang releases the muscle layer, clears transforming Heat, and is especially useful when a cold begins to “sink inward” with eye pain and rising fever.
2. Common Cold
For patients suffering from a common cold, Chai Ge Jie Ji Tang is an excellent choice if their symptoms match the specific pattern of "wind-cold turning into heat."
-
Key signs to look for: The patient's chills are gradually fading, but their fever is getting higher, they aren't sweating, and they have a headache and a dry nose. The formula helps relieve these mixed symptoms and gets the body back on track.
3. Influenza (The Flu)
During flu season, if a patient presents with the classic symptoms described above, this formula can be highly beneficial.
- Its dual action of releasing the exterior and clearing interior heat helps bring the illness under control. It effectively soothes the intense fever, headaches, and severe body aches associated with the flu, while supporting the body's natural immune response for a faster recovery.

4. Upper Respiratory Tract Infections
Upper respiratory infections are often triggered by outside pathogens. When an infection causes symptoms like fever, chills, sore throat, and headaches—combined with signs of internal heat (like restlessness or a dry mouth)—Chai Ge Jie Ji Tang can be used.
- It efficiently treats both the surface infection and the internal inflammation, helping to relieve discomfort and shorten the overall duration of the sickness.
