Overview

Chai Ge Jie Ji Tang — Bupleurum and Kudzu Decoction to Release the Muscle Layer — is a formula from the Ming Dynasty physician Tao Jie’s Shang Han Liu Shu (Six Writings on Cold Damage) for treating febrile illness that has progressed beyond the initial exterior stage and is now lodged in the muscle layer, where it produces simultaneous exterior symptoms and early interior Heat. It is most clinically relevant for lingering colds and flu where the initial exterior pathogen has not been fully released but has begun generating interior Heat — producing the characteristic picture of persistent fever with neck and upper back stiffness, eye pain, and early thirst. It bridges the gap between pure exterior-releasing formulas like Yin Qiao San and interior Heat-clearing formulas like Bai Hu Tang.

TCM pattern

Prescribed for pathogen lodged in the muscle layer with beginning interior Heat, characterised by: persistent fever (often with chills), stiffness and aching of the neck, upper back and muscles, eye pain and dryness, nasal dryness, mild thirst, a slight irritability, a thin yellow tongue coating, and a wiry, slightly rapid pulse.

Key herbs

1. Ge Gen (Pueraria lobata root) — the principal herb; releases the muscle layer, disperses Wind-Heat, reduces fever, relaxes the neck and upper back muscles and generates fluids
2. Chai Hu (Bupleurum chinense root) — releases the half-exterior, half-interior Shao Yang; disperses Wind and reduces fever
3. Qiang Huo (Notopterygium incisum rhizome) — expels Wind-Cold from the exterior and muscles; particularly effective for the neck and upper back stiffness
4. Bai Zhi (Angelica dahurica root) — disperses Wind-Cold from the head and face; alleviates headache
5. Huang Qin (Scutellaria baicalensis root) — clears the beginning interior Heat; anti-inflammatory
6. Shi Gao (Gypsum fibrosum) — clears interior Qi-level Heat; alleviates thirst
7. Jie Geng (Platycodon grandiflorus root) — opens the Lung Qi and guides the formula upward
8. Bai Shao (Paeonia lactiflora root) — nourishes Blood and Yin; moderates the formula
9. Gan Cao (Glycyrrhiza uralensis root) — harmonises the formula

Conditions treated

1. Lingering cold and flu where the exterior pathogen has not been fully released and interior Heat is beginning — the formula’s primary indication
2. Neck and upper back stiffness with fever from Wind-Cold invasion of the muscle layer
3. Persistent fever with muscle aches after the initial acute stage of an infection
4. Early stage COVID-19 or influenza with the mixed exterior-interior pattern
5. Sinusitis and upper respiratory infections where the pathogen has partially internalised
