Have you ever enjoyed the scent of a rose, squeezed an orange peel, or rubbed your fingers over the needles of a fir tree or an herb in your garden? If so, you have experienced the aromatic qualities of essential oils. These naturally occurring, aromatic compounds are found in all parts of the plant—the leaves, seeds, bark, stems, roots, flowers, citrus peelings and other parts of plant. They are extracted through steam distillation or cold pressing.
Essential oils provide plants with protection against environmental threats and play a role in plant pollination. In addition to their intrinsic benefits to plants and being beautifully fragrant to people, essential oils have long been used for food preparation, beauty treatment, and health-care practices.
