Wild Parsnip: Identification, Itching & Avoiding Contact

Wild Parsnip (Pastinaca sativa)

Wild parsnip resembles Queen Anne's lace with white flower clusters, but the similarity ends there. It is an invasive plant whose sap contains furanocoumarins that cause phytophotodermatitis—a severe skin reaction when sap contacts skin and is then exposed to sunlight.

Symptoms

• Intense itching, burning
• Redness, blistering
• Long-lasting hyperpigmentation (dark spots)

Prevention & Treatment

• Learn to identify the plant (grooved stem, compound leaves, yellow-green flowers).
• Wear long sleeves, pants, gloves when in areas where it grows.
• If exposed, wash skin immediately with soap and water; avoid sun exposure for 48 hours.
• See a doctor for severe reactions.
