An allergy syndrome, where there is cross reactivity between mugwort (a pretty nondescript weed, pollen can cause hay fever and trigger asthma) and a wide range of foods, including:

• Fruit – esp apple, melon, peach, orange, watermelon
• Tomato
• Vegetables – esp  celery, carrot, green pepper, onion, parsnip
• Spices – eg mustard, paprika, pepper, coriander, basil, dill, oregano, parsley, thyme, anise, caraway, fennel, tarragon
• Chamomile
• Sunflower seeds

You are not automatically allergic to everything, just be aware that you are at higher risk of being allergic to something else on the list if you are allergic to one or more things.
