An essential oil is a concentrated hydrophobic liquid containing
volatile (easily evaporated at normal temperatures) chemical compounds
from plants.
Essential oils are also known as volatile oils, ethereal oils,
aetheroleum, or simply as the oil of the plant from which they were
extracted, such as oil of clove.
An essential oil is essential in the sense that it contains the essence
of the plant's fragrance—the characteristic fragrance of the plant from
which it is derived.
