Wild parsnip

Wild parsnip grows in sunny areas, often along roads and in prairies. The plant has large bunches of yellow flowers on a thick stem. Touching sap from the wild parsnip plant and then being in sunlight can cause a skin reaction that looks like a burn. Within a day, the skin turns red and might develop painful blisters. You might not notice a mild wild parsnip skin reaction. But a severe reaction can cause skin to change color and stay that way for months or years.

Soothe the skin with a cool, wet cloth or moisturizing lotion. Talk to your health care professional if the blisters are severe or last longer than two weeks.
