Neroli essential oil is produced from the blossom of the bitter orange tree. Its scent is sweet, honeyed and somewhat metallic with green and spicy facets. In fact, there are three oils derived from this same tree—orange is derived from the orange peels, Petitgrain from the leaves and twigs, and Neroli from the flower. Much research has been conducted regarding the aroma of Neroli essential oil. According to research, Neroli instills relaxation, uplifts mood, reduces feelings of anxiousness, and promotes overall well-being. Applied topically, Neroli can be used to soothe skin and reduce the appearance of blemishes.
