                                According to the Australasian Society of Clinical Immunology and Allergy, Oral Allergy Syndrome (OAS) is a type of food allergy that can cause a tingling or burning sensation in the mouth. This is one of several possible explanations for why your mouth might burn when you eat broccoli, a common and otherwise healthy vegetable.
