Mugwort pollen allergy and food allergies

It is known that people suffering from mugwort pollen allergy often also experience symptoms when eating certain foods. This phenomenon is caused by a so-called "allergen family" within botanically related plant foods and pollen. More specifically, the same proteins found in pollen are found in various plant foods.

It is most common for itching or burning in the mouth and throat area or sometimes swelling in the mouth and throat, which can lead to difficulty swallowing. Less common symptoms are nausea, hives, or even asthma, indigestion and circulatory problems.
