Currently there are five grades of Ylang Ylang Oil: Extra Superior, Extra, First, Second and Third. Ylang is such a popular oil in aromatherapy the possibilities of adulteration are quite high, as is blending/manipulation of the various grades to make an affordable oil. We also offer Ylang Ylang Extra as an Organic Oil.
Use in moderation since its heady scent can cause headaches or nausea.
