Coriander is a herb, commonly called cilantro in the USA. As a 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 caused by profilin
proteins which can cause allergic reactions in uncommon circumstances. Some profilin proteins can give oral allergy type symptoms and is more specifically called Celery Mugwort Spice Syndrome
Coriander also contain chemicals called furanocoumarins
, these can act as a contact allergen. When they come in contact with the skin it can become more sensitive to sunlight which can cause blistering. This is more common as an occupational allergy with people who pick, pack and process coriander.
Coriander is a low FODMAP food. FODMAP
stands for F
olyols. Foods high in FODMAPs can cause symptoms of food intolerance, affecting the gastro intestinal system and this can be mistaken for a true IgE food allergy.
Coriander is a food low in salicylates. Salicylates
have the potential to cause gastrointestinal food intolerance symptoms in people who are sensitive to salicylates.
