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.
