Alocasia odora

Alocasia odora, also known as night-scented lily, Asian taro or giant upright elephant ear, is a species of flowering plant native to East and Southeast Asia (Japan, China, Indochina, Assam, Bangladesh, Borneo, Taiwan).

[4] Alocasia odora leaves and stems are used as a green vegetable in the cuisines of Southeast Asia, and often used to flavor soups or stir-fried dishes.

Nonetheless, the plant is actually inedible when raw, and may cause mild to significant gastrointestinal discomfort, due to the composition of its leaves, which are covered in microscopic, needle-shaped raphides (or calcium oxalate crystals).

[5] Consumption of undercooked aroid leaves can result in several uncomfortable symptoms; side effects range from an itchy, sharp sensation in the esophagus, similar to a feeling of “broken glass” or sand being swallowed (usually lasting no more than several hours), to abdominal pain, hot and cold flashes, nausea and vomiting.

[6][7][8] Typical of leafy green vegetables—and despite its toxicity if prepared incorrectly—the leaves of this plant are rich in vitamins and minerals, including thiamin, riboflavin, iron, phosphorus and zinc.
