An essential oil is a liquid that is generally distilled (most frequently by steam or water) from the leaves, stems, flowers, bark, roots, or other elements of a plant. Essential oils, contrary to the use of the word "oil" are not really oily-feeling at all. Most essential oils are clear, but some oils such as patchouli, orange and lemongrass are amber or yellow in color.
Essential oils contain the true essence of the plant it was derived from. Essential oils are highly concentrated and a little goes a long way.
What is Carrier Oil?
A carrier oil is a vegetable oil derived from the fatty portion of a plant, usually from the seeds, kernels or the nuts.
If applied to the skin undiluted, essential oils, absolutes, CO2s and other concentrated aromatics can cause severe irritation, sensitization, redness or burning or other reactions in some individuals. Carrier oils are used to dilute essential and other oils prior to topical application. The term carrier oil is derived from their purpose in carrying the essential oil onto the skin.
