Essential oils are volatile, fragrant essences extracted from plants. They provide the aromas customarily associated with a given plant. Many commercial essential oils are extracted out of plants with alcohol or hydrocarbon solvents such as hexane. All of the essential oils used in Aurum natural products are steam-distilled from plant materials. This method protects the integrity of the various compounds contained in each essential oil. To help ensure purity, the herbs used in these essential oils are never sourced from China. Because essential oils are quite potent they are diluted in carrier oils before skin application.
