Orange allergy is an immune response to certain proteins found in oranges. While less common than some other food allergies, it can cause adverse reactions in sensitive individuals. Reactions can range from mild oral allergy symptoms to more severe systemic effects, and they can occur from both eating oranges and exposure to orange peel or juice....
