The dried body of silkworm larvae (Bombyx mori) that have died of infection by Beauveria bassiana fungus. Enters the Liver, Lung, and Stomach channels. Salty, pungent, and neutral, it both extinguishes internal Liver wind and dispels external wind-heat, while transforming phlegm and dissipating nodules. Used for convulsions, facial paralysis, sore throat, and scrofula.
