Jack-in-the-Pulpit

Arisaema atrorubens

Jack-in-the-pulpit, or Indian turnip, held a real place in the plant knowledge of many Native American nations, from the Iroquois to the Cherokee, who recognized both its danger and its usefulness. The raw corm burns the mouth ferociously if bitten into, thanks to needle-like calcium oxalate crystals, and this fact was put to inventive use, from settling disputes to testing a person's grit. After careful drying or cooking, which breaks down the irritating crystals, the corm was sometimes prepared as a starchy food, and various parts of the plant were worked into topical preparations for headaches, sore eyes, and rheumatism. It remains, above all, a plant respected for what it can do to an unprepared mouth as much as for what it can offer a well-informed hand.

Safety.

Every part of this plant, and especially the fresh corm and leaves, contains dense concentrations of calcium oxalate raphide crystals. Chewing or biting into fresh plant material causes immediate, intense burning and swelling of the lips, tongue, mouth, and throat, and in significant amounts can make swallowing or breathing difficult. Handling the plant can also irritate sensitive skin. This is not a plant for home teas, tinctures, or food preparation, and the traditional food use required extensive, careful processing that is not something to attempt without expert guidance. Keep it away from curious children and pets, and if exposure occurs, seek medical attention promptly. As always, consult a qualified healthcare professional or toxicologist with any concerns.
