Modern Research Perspective
Processed Pinellia contains alkaloids, polysaccharides, lectins, and other constituents whose profile changes with 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, interactions, and monitoring are essential.
Traditional Function
Prepared 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 Pinellia can be strongly irritating and toxic.
