Clinical notes

As the He-Sea (Earth) point of the Triple Burner, TB11 is crucial for treating disorders of the entire meridian and is particularly effective for damp-phlegm accumulation. It is renowned for dissipating nodules, scrofula, and goiter, especially when associated with phlegm-heat. It also clears heat from the Triple Burner, making it useful for febrile diseases with chills and fever, and calms the spirit in cases of epilepsy or mental disorders due to phlegm. It is often paired with ST40 for phlegm resolution.
