a target = "" title = "natural essential oils herbalist" href = "http://www.verdirimedi.it/olii-essenziali-c7161/"> essential oils make up the most refined one can be obtained from a plant. The personality, the soul and the vital energy of the plants are concentrated in them. These are volatile substances that evaporate rapidly, diffusing their aroma into the air.

They are substances with a high concentration and This is precisely why they differ from other phytoderivatives: in a gram of essential oil the content of more than 100 grams of the original plant is on average!

Precisely because of this very high concentration is a product with potential very strong benefits that make it precious and sought.

Their consistency is generally fluid, more or less dense and oily; some are colorless, others of varying color.

It is assumed that the plants use their essential oils to" communicate "with the outside world: in some cases to attract pollinating insects, in others to defend themselves from enemies by removing or destroying them.

Each essential oil is distinguished not only for its chemiotype also for other different characteristics. Some of these correspond to its vibrations, called notes. There are three types of notes:

• Head Notes: refer to the spiritual plane and the intellectual sphere. These are generally volatile oils that are pleasant to smell. They stimulate concentration and have beneficial effects on mental balance.
• Heart Notes: They work on the emotional level and on temperament. Mostly they are essential oils of flowering from the wide range of aromas, from the softest to the most acre. Induce relaxation, availability, relaxation and relief.
• Basic Notes: Convolute the physical plane. They are generally oils derived from wood and/or bark, resinous, warm, sometimes severe aromas that reinforce the balance, soothe and relax.

How are Products?

There are several ways to extract essential oils from plants. The choice depends on several factors, but mainly on the characteristics of the plant and the result to be obtained.

• Distillation in steam current: through a special apparatus called the alembic, the essential oil of the original plant is separated by means of a stream of water vapor; this procedure is suitable for most plants.
• Pressure distillation: the plants are subjected to special equipment, to a 'cold pressing "mechanical operation; this procedure is mainly used for citrus fruit.
• Carbon dioxide extraction (CO ₂ ): Modern and integral extraction that sees the use of an inert gas such as carbon dioxide as a transport solvent for essential oils. The technique is still little known and little known, also because it requires particularly expensive systems.
• Cold extraction with solvent called "absolute" : thanks to the use of suitable equipment, the petals of the flowers of the plant are put in contact with organic fats to which they release their aroma. In this way a solid mass is created, called the ointment from which, with the use of alcohol, the essential oil is extracted.
