The sweetest and perhaps most nutritious of citrus, the orange has long been employed in aromatherapy, beloved for its support of calming, cooling, and restorative sleep effects. Native to China, the orange is prolific in Chinese medicine, which uses the dried peel in applications for cough, colds, and digestive disorders. Vitamins A, B & C are top-of-the-line in an orange, superior in supporting efforts to stave off infection. Pharmacology research indicated its beneficial properties related to skincare, respiratory and circulatory systems and digestive. Cold press of the freshly ripe or almost ripe peel extracts a rich but sweetly fresh yellow or amber-orange oil.
