Called essential oil (or sometimes plant essence) the concentrated liquid and hydrophobic volatile aromatic compounds of a plant. It is obtained by distillation or chemical extraction solvent (water, alcohol, etc.).. Contrary to what the name implies, these extracts may not be oily.
"Product fragrant, generally of complex composition, obtained from a raw vegetable botanically defined either by steam distillation of water or by dry distillation, or by a mechanical process without adequate heating. The essential oil is most often separated from the aqueous phase by a physical process involving no significant change in its composition. "
It is a mixture of various molecules, including in particular terpenes (non-aromatic hydrocarbons) and oxygenates (alcohols, aldehydes, ketones).
Obtaining essential oils is done either by entrainment of water vapor in a distillation process or by dry distillation or by cold expression (zest). In the latter case, some ambiguity exists in the name of essential oil. According to the AFNOR, use the term gas while the French Pharmacopoeia and European Pharmacopoeia use the term essential oil. The term essential oil has been selected by experts in pharmacognosy. The amount of essential oil in plants is still low, sometimes very low or negligible. This explains the high cost of essential oils, it is related to the rarity and not the extraction process remains the same for most plants. Sometimes it takes several tons of plants for a liter of essential oil. There are different methods of extraction (often chemical), but for aromatherapy, only a few provide a good quality final.
Administration method of essential oils
Atmospheric scattering: This is the easiest to use. But only use a special diffuser that allows a micro spread, no incense burner that alters the essential oils by heating. Do not let the air diffuser permanently active. Ten minutes per hour is quite enough.

I use the following oils:
20% of Eucalyptus Radiata
20% of Lemongrass
