Essential oils, called volatile oils or ethereal oils, are natural metabolic secretions of plants, the role of which is not yet fully understood by science. Some specialists consider them to be true plant hormones, fluid manifestations of the immune system of plants, in the sense that they contribute to the removal of pests, attracting, instead, pollinating agents, which are some insects and birds. Small, light–colored spherical structures, is, in fact, modified filaments, which behave like some secretory glands of essential volatile oils. They are the ones who give the fragrance of the aromatic plant and have, in the case of salvation, medicinal curative properties, such as fever reduction, blood cleansing, and relieving pain. Essential oils are products isolated from plants or organs through a physical process that have a certain volatility (higher or lower) and possesses an agreeable odour characteristic of the source from which they originate. They are also known as volatile or essential oils and their name are usually given by the popular name of the plant from which they are extracted. The most important characteristic of these mixtures, which also gives the special economic value, is the specific smell. This is the basis for their use in perfumery, cosmetics and the food industry.

The rose, for example, predominantly secretes etheric oil at the level of flowers, while ginger produces more aromatic oil in the rhizome. Each the volatile oil is unique, being different even within the same plant, and has wonderful applications and as varied as Nature itself.

Numerous compounds that make up essential oils have been identified. Only the mint oil has no more than 200 different components. Many the compounds are structural isomers 1.
