Pinellia rhizome (processed)

Ingredient Profile

Chinese Name法半夏
PinyinFa Ban Xia

Modern Research Perspective

Processed Pinellia contains alkaloids, polysaccharides, lectins, and other constituents altered by processing. Experimental studies have examined antiemetic, respiratory, gastrointestinal, and anti-inflammatory pathways.

Human evidence is preparation-dependent and limited. Improper processing can cause oral, gastrointestinal, or systemic toxicity; authentication, processing validation, dose, pregnancy precautions, interactions, and monitoring are essential.

Traditional Function

Processed Pinellia Rhizome is traditionally pungent, warm, and drying. It is used to transform phlegm, descend rebellious qi, relieve nausea, and disperse nodules. Proper processing is essential because raw material can be strongly irritating and toxic.
