Aromatherapy is the practice of using volatile plant oils, from different parts of plants like bark, roots, leaves, flowers, stems etc. for psychological and physical well-being. These oils are called Essential Oils in general.
Essential oils, the pure essence of a plant, have been found to provide both psychological and physical benefits when used correctly and safely. Absolutes, Elixirs and Synergies are also some of the forms of aromatherapy oils. Although different distillation processes are being used, the term Essential Oil is used in general to describe all these.
