About

Symplocarpus foetidus, commonly known as skunk cabbage or eastern skunk cabbage, is a low-growing plant that grows in wetlands and moist hill slopes of eastern North America. Bruised leaves present an odor reminiscent of skunk.

How this plant poisons

Since its roots are antispasmodic, diaphoretic, diuretic, emetic, expectorant, and slightly narcotic, it is not recommended to consume the raw plant directly. While high quantities of the root can produce nausea and vomiting, headaches, and dizziness, handling the fresh leaves can burn skin. Other symptoms of poisoning include swelling of the lip, throat, and tongue. This is due to calcium oxalate crystals, which are moderately harmful to humans. It is possible to eliminate the toxicity with care, such as changing the water frequently when boiling the leaves, or thoroughly drying the plant.
