Botanical Description

Pinellia ternata (ban xia) is a small perennial herb in the Araceae native to China, Japan, and Korea, where it grows in fields, grassy slopes, and disturbed ground. It arises from a globose underground tuber (corm/rhizome) and bears long-petioled leaves that are simple in young plants but become three-parted (ternate) at maturity, with a small bulbil often borne at the junction of leaflets. The inflorescence is a slender green-to-purplish spathe enclosing a spadix with a long whip-like appendage.

Native Region: China North-Central, China South-Central, China Southeast, Hainan, Inner Mongolia, Japan, Korea, Manchuria, Nansei-shoto, Taiwan

⚠ Rule-Based Cautions

These entries come from the deterministic rule tables that gate Verscienta's formula tools — classical pair prohibitions, pregnancy and lactation contraindications, dose ceilings, and drugs outside the Chinese Pharmacopoeia. The botanical-genus entries are different: advisory notes are not part of the safety screen; the Aristolochia genus check is.
