Therefore, complementary medicine is widespread in clinical practice, mainly in pediatric settings, and pleasing to parents.Nutraceuticals, such as ''a food (or part of a food) that provides medical or health benefits, including the prevention and/or treatment of a disease,'' are commonly prescribed by pediatrics as well as self-prescription by parents. There is evidence that some components exert beneficial effects in allergic diseases. In this regard, the supplementation with some food supplements may significantly reduce symptom severity and functional parameters.Some compounds, including micronutrients, vitamins, probiotics, herbal medicines, could positively and safely be used in children with allergic diseases as add-on or preventive remedies. Nutraceuticals should not substitute drugs.
