Sweet orange oil is extracted from a variety of an orange tree which is smaller and less hardy than the bitter orange tree. The tree is native to China but is now commonly found in Europe and the US. The oil is extracted by cold expression from the peel of the orange fruit.
Sweet orange essential oil is used in aromatherapy to treat oily skin, bronchitis, constipation, colds, flu, insomnia and stress. The properties of sweet orange oil overlap with bitter orange essential oil and orange blossom essential oil.
