Although the botanical differences between mandarin and tangerine are slight, the oils expressed from each differ in aroma and are not considered interchangeable in aromatherapy. The floral, neroli-like undertones of mandarin are evocative and sensual. Mandarin is used in combination with other citrus oils in colognes and fantasy-type perfumes. (See Tangerine.) Aromatherapy benefits: uplifting, cheering, sensual.
