Traditional Chinese Uses
Tian Nan Xing (arisaema rhizome) is a warm, pungent herb that dries Dampness and transforms stubborn Phlegm — particularly cold-type Phlegm that has become lodged in the channels and orifices. Its most significant applications are for Wind-Phlegm patterns causing convulsions, stroke sequelae with paralysis, facial deviation, numbness, and dizziness. Applied externally, it treats snake bites and carbuncles. It is highly toxic in its raw form and must be properly processed before internal use, with bile processing (Dan Nan Xing) creating a cool-natured form for heat Phlegm patterns.

Botanical Description
Tian Nan Xing is the dried corm-like rhizome of several closely related species of Arisaema (Araceae), chiefly A. erubescens, A. heterophyllum, and A. amurense, all perennial tuberous herbs native to East Asia. Each year a single false stem (actually a long fleshy petiole) emerges from the depressed-globose corm, bearing one or two compound leaves with 7-19 radiating lance-shaped leaflets resembling a partly-opened hand. The inflorescence is a typical aroid spadix enclosed in a hooded green or purple-striped spathe with a long whip-like tip, ripening into a dense head of bright orange-red berries. The fresh corm is intensely acrid and irritant due to needle-like calcium oxalate raphides and must be processed (boiled with ginger, alum, or bile) before therapeutic use; raw material is considered toxic.
