Parsnip Allergy


Key Allergens

Allergic reactions to parsnip are most likely to be caused by Bet v 1-like proteins, which cause reactions in people sensitised to birch tree pollen and give oral allergy type symptoms.

Parsnips also contain furocoumarins which can cause urticaria and contact dermatitis.

Another suggestion is that plants in the Apiaceae family contain profilin proteins which can cause allergic reactions in uncommon circumstances.
