This formula is based on Cang Er Zi San (1253). The original formula traditionally dispels pathogenic Wind (both Wind-Heat and Wind-Cold) that has lodged in the nasal passages and thus may help alleviate nasal discharge. The base formula has been enhanced with the inclusion of seven additional herbal ingredients. These herbs may release the Exterior and dispel Wind-Heat; release the Exterior and dispel Wind-Cold; clear Heat from the Lung.
