Botanical Overview
Heart Of Jesus (Caladium bicolor) belongs to the Araceae family. Limited but reliable traditional records indicate this plant has recognized medicinal applications in one or more healing traditions. 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.
