Essential Oils are made from the volatile and highly fragrant part of the plant. They are used in aromatherapy and are often referred to as aromatic oils or ethereal oils. They are believed to each have their own health benefits such as strong healing powers, so they're often used as alternatives to medicinal cures. Essential oils quickly penetrate the body through the skin and the respiratory tract, and they enter and leave with body without leaving any toxins behind.
Commonly, they are used in perfumes, cosmetics and flavoring. They are usually distilled or put through some kind of distillation process, but essential oils can also be cold-pressed (like oils of citrus fruits) or burned (for instance, made into incense). The most common essential oils are lavender, peppermint, and eucalyptus; however, there are more than 400 in production.
