Aromatherapy is an ancient form of alternative medicine that uses essential oils and other aromatic compounds from plants to help alter a person's mood or health. It is often used in combination with other alternative medical practices and spiritual beliefs to achieve the desired state of wellbeing.

The general idea behind aromatherapy is that disease can be treated or even prevented by applying essential oils. The aroma of oils extracted from various herbs and plants, referred to as essential plants, brings the mind and the body into a state of equilibrium, thus helping to treat and prevent mental or physical disorders. These essential oils are derived from various flowers, fruits, trees, herbs and resins and may be applied in a series of ways. One is through aerial diffusion, to disinfect the air or give a fragrance. Direct inhalation is another popular application, used for respiratory disinfection, decongestion, and psychological purposes. However, aromatherapy is perhaps most widely used for massages, combining their properties with the therapeutic power of touch.
