What is an Onion Allergy?

An immunological response to the proteins found in onions is known as an onion allergy. When a person who has an allergy to onions eats onions, their immune system misinterprets the proteins and releases histamine, which sets off an allergic reaction. This reaction can take many different forms, ranging from minor discomfort to severe reactions.

Some people may experience mild symptoms, and others may exhibit severe reactions that require immediate medical attention.
