Background: Oral Allergy Syndrome (OAS) is a food allergic reaction towards fruit, vegetable and nut causing clinical symptoms in the form of itching, pain, vascular edema, and a narrow throat. In this case report, we reported management two cases of oral allergy syndrome due to banana and longan. Cases: The first case reported a 20-year-old man complaining of both upper and lower swollen lips after eating longan fruit.  The second case was a 54-year-old woman complaining of pain and discomfort in the upper lip, mouth corners, left and right inner cheeks, palate and especially on the tongue. She had had an Ambon Banana the day before. Case Management: Both patients were given antihistamine treatment and informed to avoid the suspected fruits which caused the allergic reaction. The diagnosis is established using the oral food challenge method.  Conclusion:  The principle of management of OAS cases is to identify and avoid allergens. Antihistamines are the drug of choice for this case.
