Background

Skunk cabbage (Symplocarpus foetidus) is a plant native to swamps and wetlands in North America. It gets its name from the unpleasant odor it releases.

Skunk cabbage root is used as medicine. But it contains calcium oxalate, which can irritate the kidneys and increase the risk for kidney stones.

People use skunk cabbage for asthma, headache, seizures, toothache, wound healing, and many other purposes, but there is no good scientific evidence to support these uses.
When taken by mouth: Skunk cabbage is possibly safe when consumed in the amounts found in foods. There isn't enough reliable information to know if taking skunk cabbage in larger amounts as medicine is safe. Large amounts can cause nausea, vomiting, diarrhea, headache, dizziness, and other side effects.
