Essential oils, which can be obtained from the leaves, fruit, bark or root
parts of plants, are natural products that are liquid at room temperature,
usually colorless or light yellow. Although essential oils are defined as
oils because they do not mix with water, they are different from fixed
oils and are largely composed of terpenes in their chemical structure.
