Cicada Slough Classic Formulas — Natural Herb Library

Primary Actions

Releases wind-heat from the exterior - Chan Tui is used for early wind-heat presentations with sore throat, mild fever, and superficial irritation.
Benefits the throat and voice - it is a classic light herb for hoarseness, swollen throat, and constrained heat at the surface.
Vents rashes and relieves itching - traditional use includes measles that do not vent well, urticaria, and pruritic wind-type eruptions.
Extinguishes wind and stops spasms - Chan Tui is also used in combination formulas for fright-wind, childhood convulsion patterns, and tremulous movement associated with wind.

Chan Tui with Niu Bang Zi and Bo He - classic wind-heat throat and rash-venting pairing logic.
Xiao Feng San - itching formula tradition in which Chan Tui helps vent wind from the skin and reduce pruritus.
Chan Tui with Jiang Can and Gou Teng - spasm- and convulsion-oriented strategy when wind and agitation rise to the surface.

TCM herb summaries describe Chan Tui as sweet, salty, and slightly cold, entering the Lung and Liver channels, with actions of dispersing wind-heat, venting rashes, benefiting the throat, brightening the eyes, and stopping spasms.
Traditional use often emphasizes pediatric or dermatologic patterns because the herb's light outward action helps guide constrained pathogens or rash expression to the surface.
Its classic identity remains distinct from heavier anticonvulsant or sedative substances even though later research has explored neuroprotective effects.
