Mouth allergy symptoms

Oral Allergy Syndrome i.e. mouth allergy is most commonly associated with allergy to birch pollen, but can occur with other pollens such as ragweed, mugwort sage, plantain, and grasses. Fruits and nuts are the foods most commonly implicated, but other foods can cause the symptoms as well.
Most authorities say it is not necessary to avoid all foods associated with a given pollen allergy. They recommend avoiding only the foods which cause symptoms of mouth allergy. Often it is the raw food that causes the mouth allergy symptoms, and many people find they can tolerate these foods without symptoms when the foods are well cooked.
