Aniseed is a spice, also known as anis. As a very rare allergy it is not well studied and there has been no confirmation of which allergens are causing the reactions.
Allergic reactions 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.
Another suggestion is that plants in the Apiaceae
family contain profilin proteins
which can cause allergic reactions in uncommon circumstances.
Allergy to aniseed is loosely linked to Pollen Food Allergy Syndrome
. You may have Pollen-Food Allergy Syndrome if you suffer from aniseed allergy with oral allergy symptoms to 3 or more of the foods mentioned in the cross reactivity section.
Aniseed is in the family Apiaceae, other spices in this family are coriander, caraway seed, celery, chervil, cumin, dill, fennel and parsley.
If sensitised to birch tree pollen you may have Pollen Food Allergy Syndrome and may also react to apple, carrot, kiwi, pear, peach, plum, nectarine, apricots, cherries, tomato, celery, potato, parsnip, pepper, dill, peas, fennel, hazelnut, walnut, almonds, peanuts, lentils and bean.
