Arisaema triphyllum (Scientific name)

General poisoning notes:

Jack-in-the-pulpit (Arisaema triphyllum) is a native plant found in wet soils in parts of eastern Canada. The plant contains calcium oxalate raphide crystals, as do many other members of the family Araceae. When ingested, these crystals can cause severe pain and burning in the lips, mouth, and throat (Lampe and McCann 1985).

Notes on poisoning:

  • Ingesting Jack-in-the-pulpit causes a burning sensation, with associated inflammation, edema, and salivation. Treatment includes cool liquids held in the mouth to provide relief. The oxalates are insoluble and do not cause systemic poisoning in plants (Lampe and McCann 1985).
