Essential oils are useful in the practice of aromatherapy and can deliver positive benefits to the mind, body and spirit. An essential oil is not actually an “oil” in the traditional sense of the word. Essential oils are the volatile, aromatic oils obtained by steam or hydro distillation of botanicals. Different parts of the plants can be used to obtain essential oils, including the flowers, leaves, seeds, roots, stems, bark, wood, etc. These oils are the ‘soul’ of the plant and contain all beneficial properties as found in nature. Most essential oils are primarily composed of terpenes and their oxygenated derivatives. Certain cold-pressed oils, such as the oils from various citrus peels, are also considered to be essential oils but these are not to be confused with cold-pressed fixed or carrier oils such as olive, grape seed, apricot kernel, etc. which are non-volatile oils composed mainly of fatty acid triglycerides. Benefits of essential oils include soothing, calming, grounding, refreshing, centering, and warming to the system.
