Essential oil

You have probably heard of "aromatherapy" candles with essential oils. But the big question is: What are essential oils anyway? Well, basically, essential oils are "oils" or "essence" that have been extracted from various species of flowers, fruits, herbs, leaves, seeds, resin, stems, roots, and bark of botanicals.

Essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. It is also known as volatile oils, ethereal oils or aetherolea, or simply as the "oil of" the plant from which they were extracted, such as oil of clove. An oil is "essential" in the sense that it carries a distinctive scent, or essence, of the plant. Essential oils do not form a distinctive category for any medical, pharmacological, or culinary purpose.
