Essential oils are non-water-based, natural aromatic phytochemical compouds found in the seeds, bark, stems, roots, flowers, and other parts of plants. They are fat soluble — though they do not include fatty lipids or acids found in vegetable and animal oils — and are very clean, almost crisp, to the touch and are immediately absorbed by the skin. Pure, unadulterated essential oils are translucent and range in color from crystal clear to deep blue. They can be both beautifully and powerfully fragrant and have been used throughout history in many cultures for their medicinal and therapeutic benefits. Modern scientific study and trends toward more holistic approaches to wellness are driving a revival and new discovery of essential oil health applications. Essential oil diffusers are devices that send essential oil elements into the air so that you can experience the health and medicinal benefits of essential oils firsthand. Diffusers are a favorite method for air purification and are used in wellness to help promote relaxation among additional benefits of aromatherapy.
