Essential Oil

Essential oils are sweet-smelling (aromatic) and volatile chemical compounds found in selected plant species called aromatic plants. They are termed volatile because they readily change from liquid to gaseous state at room temperature. It is due to the volatility property that they are able to quickly diffuse through the air and interact easily with our senses. The oils are stored in a plant’s specialized secretory structures such as glands, ducts, and cavities, where they occur in very small quantities.

Actually, Essential oils are derived from various herbs and plants parts, most commonly their leaves and bark.
