Essential oil意思

"Essential oil" is a term used to describe a concentrated, volatile liquid that is extracted from various parts of plants, such as the flowers, leaves, stems, bark, roots, or peel. These oils are highly aromatic and are often used in aromatherapy, cosmetics, perfumes, and various other products. Essential oils are believed to contain the "essence" or "vital energy" of the plant from which they are derived.

Essential oils are made up of chemical compounds that vary depending on the plant source. They are typically obtained through steam distillation, cold pressing, or, in some cases, through the use of solvents. Each essential oil has its unique properties and is used for a variety of purposes, including therapeutic, cosmetic, and culinary applications.

It's important to note that essential oils are highly concentrated and should be used with caution, as they can have strong effects on the body. They should always be diluted before use, especially when applied topically to the skin.
