Pinella, more commonly known in traditional Chinese herbal practice as Pinellia ternata or ban xia, is a tuberous perennial herb in the Araceae family native to China, Korea, and Japan. It produces arrow-shaped leaves and a characteristic spathe-like flower structure, while the tuber is the part used only after proper processing.
In traditional East Asian herbal systems, processed pinella has been used in carefully prepared formulas, especially for phlegm-related patterns and digestive imbalance. Raw plant material is not used in the same way and is considered irritating.
Pinella is a herb where correct identification, traditional processing, and practitioner guidance are especially important.
Pinellia ternata or ban xia is a highly invasive weed
