Citrus fruits, including C. sinensis, have been investigated as a delivery system for vaccines; the fruits were injected with the vaccine and then eaten.9  Most modern research, however, is focused on new efficient ways to grow, protect and harvest oranges.

However, the juice and pulp have been used as a digestive aid, to relieve gas pains, swelling and constipation.2,5  Oranges also contain vitamins A, B-complex and C, flavonoids and antioxidants.2,6,7  The fruit also has a high folate content.8  The dried orange peel has been used to treat coughs and colds.5,7  
Orange Peel: The essential oil extracted from the peel through either cold expression or steam distillation, has a sweet citrus aroma.7  The orange scent is a combination of lemon-scented citral and limonene, lavender-scented linalool and pine-scented terpineol. Topical applications of the essential oil are used to soften dull and oily complexions and soothe mouth ulcers.
