Description
Ma Huang Tang (Ephedra Decoction) is the classic diaphoretic formula for Wind-Cold excess with no sweating. It forcefully opens the pores, releases the exterior, and disperses Lung Qi to stop wheezing. Characterized by strong chills, fever (chills predominating), body aches, and absence of sweating, this formula should be used with caution and discontinued once sweating begins.
