Anaphylaxis to Dill
Chiu and Zacharisen note that allergic symptoms caused by spices and herbs are infrequent and usually mild but they were able to confirm a case of allergy to dill.
The person developed symptoms of oral pruritus, tongue and throat swelling, urticaria, and immediate vomiting and diarrhoea after eating foods cooked with dill or inhaling vapours from foods prepared with dill.
Skin testing with fresh dill preparation was positive and they were able to confirm that dill can cause IgE-mediated reactions
