Vegetable oils form the core of aromatherapy treatments. These oils are extracted from plant kernels, seeds or nuts. Vegetable oils work as a dilution agent. They are added to essential oils to reduce their potency and make them skin friendly. They also possess therapeutic properties.
Two methods are primarily used for the extraction of vegetable oils – cold pressed and refined. When plant materials are pressed manually to extract oils, it is referred to as cold pressed. Cold pressed oils generally possess a stronger aroma. Meanwhile, refined oils remove any plant materials that may have remained during the initial extraction. Refined oils are generally preferred for skincare products.
