How are essential oils used in aromatherapy?
Essential oils are extracted one of two ways: either by steam distillation or expression, or pressing. Distillation is the most prominent method used to extract aromatherapy oils, however. This technique involves steaming the plant matter until it breaks down. The by-product of this breakdown phase is the plant’s fragrant oil, which is cooled, separated from the water and finally filtered into its pure essential oil.
