Essential Oils are highly concentrated and potent oils extracted from plants, leaves, flowers, roots, buds, twigs, rhizomes, heartwood, bark, resin, seeds and fruits.
Essential Oils are found in special secretory glands or cells within plant life. The aromatic substances are formed and stored in certain organs of a plant as a by-product or because of its metabolism.
Each essential oil has it’s very own blueprint that is absolutely unique. The combination of the plants blueprints, the energy of the sun, soil, air and water gives each oil its individual perfume and beneficial healing properties.
The same species of plant can produce an essential oil with different properties depending on whether it was grown in dry or damp earth, at high or low altitude, or even in hot or cold climates.
According to the International Organization for Standardization, essential oils are a “product made by distillation with either water or steam or by mechanical processing of citrus rinds or by dry distillation of natural materials. Following the distillation, the essential oil is physically separated from the water phase.”

What Is Aromatherapy Base (carrier) Oil?
A carrier oil is a cold pressed vegetable oil that ‘carry” essential oils into the body. They help to dilute and spread essential oils over the body in a controlled way. In aromatherapy we only use cold pressed vegetable oils, animal fats and mineral oils are never used.
There are numerous vegetable oils which can be used as carrier oils such as olive oil, grape seed, almond, sunflower, etc. The problem with these oils is that they tend to oxidize in a fairly short time, leaving an unpleasant rancid smell. 
When you come to choose carrier oil, you must consider it has a longer shelf life and therapeutic properties. It also be absorbed quickly by the skin and it doesn’t leave it grease or sticky.
How To Perform Aromatherapy
Aromatic is the process of breathing in the essential oil. This can be done by using an essential oil diffuser, inhaling directly from the bottle or by adding a few drops to hands and cupping over nose and mouth.
Topical application is the process of applying essential oil directly to the area of concern along with the ears, hands and feet. Some oils can be applied directly and others need to be diluted with a carrier oil. Oils can also be added to bathwater or in a warm compress.
Some essential oils make excellent dietary supplements or food flavorings. Essential oil can be added to a liquid and drinking or to a veggie capsule and swallowed.
