Probably you want to know what are essential oils. This piece of writing aims to explain more about essential oils and also provides definition of essential oils.
Essential Oils are the soul of any aromatherapy treatment. These oils are "highly concentrated and volitile aromatic liquids of various mixtures of natural chemical compounds obtained from plants". They contain hundreds of organic constituents that combine together to work on many different levels. Ironically and in most cases, they are 75 to 100 times more concentrated than the oils in dried herbs.
The chemical mixture that forms an essential oil defines the different properties associated with that oil. While an oil may increase sugar absorption in the blood, another might decrease it.
Natural oils are incredibly complex in nature, even though it is possible to analyze their chemical composition. They are virtually impossible to be reproduced in lab conditions. The therapeutic properties of the oil are the resultant of all the constituents working together rather than the sum of its parts.
