Fermented leaven preparation of Ban Xia (Pinellia ternata rhizome) combined with flour and other aromatic herbs. Derived from the same Spleen and Stomach channel entry as parent Ban Xia but with added food-dispersing and stomach-harmonizing functions, used for phlegm-damp cough accompanied by food stagnation and indigestion.
Reference range for non-pregnant adults. Not a personalized prescription. Pregnancy, lactation, and pediatric use require specialist supervision.
Protective guidance only — when to avoid or use with caution. This block deliberately omits pregnancy, lactation, and pediatric dosing: any such use must be managed by a qualified TCM practitioner or appropriate specialist.
