Mango latex allergy

Raw green mango

Mango latex allergy especially with raw, unripe mangoes is common in some sensitized individuals. Immediate reactions may include itchiness at the angle of the mouth, lips and tip of the tongue. In some people the reactions can be severe, with manifestations like swelling of the lips, ulceration at the mouth angles, respiratory difficulty, vomiting and diarrhea.
This reaction develops because of anacardic acid present in raw, unripe mangoes. Cross-allergic reactions with other anacardiaceae family fruits like "cashew apples" are quite common. It is quite rare with fully ripen fruits; however, people with known case of mango fruit allergy may have to avoid them.
