Botanical Overview

Devil’s Tongue (Amorphophallus konjac) belongs to the Araceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. The arum family (Araceae) includes herbs, climbers, and aquatics with a distinctive inflorescence consisting of a fleshy spike (spadix) surrounded by a modified leaf (spathe). Many species produce calcium oxalate crystals and acrid compounds that cause intense irritation. Despite this, several are used medicinally after proper preparation.
