It is a well-recognized and generally accepted fact that allergy to fruits is a frequent cause of allergic disturbances, particularly of the cutaneous variety. Urticaria, angioneurotic edema, burning or itching sensations of the mouth, canker sores, and diarrhea are the usual types of disturbance caused by such sensitization, although it occasionally may be responsible for such manifestations as migraine, allergic coryza, or even asthma. Symptoms more often follow the eating of the raw fruit than when it is cooked, canned, or preserved. This explains the greater incidence of urticaria in the summer when more fresh fruits are ingested than at any other time of the year.
