Photo of wild parsnip plant and reaction

Wild parsnip

Wild parsnip grows in sunny areas, often along highways and in prairies. The plant bears large, flat clusters of yellow-green flowers on a thick stem. Sap from the wild parsnip plant — along with exposure to sunlight — can cause a burn-like reaction on the skin. Within a day after exposure, the skin turns red and may blister. The affected area, which feels like a mild to severe sunburn, often turns brown. This discoloration sometimes lasts for months.

Soothe the affected area with a cool, wet cloth. Consult your doctor if the reaction is painful or the blisters are severe.
