Aromatherapy oil. View of a bottle of essential orange oil used for aromatherapy. A slice of orange fruit (Citrus sinensis) is seen under the bottle. In aromatherapy, fragrant fruit, herb or flower extracts, known as essential oils, are suspended in another oil called a carrier. This mix is then massaged into the skin, inhaled or added to bathing water. They may also be used to make creams, lotions or perfumes. Aromatherapists claim that they can treat a range of disorders, particularly psychosomatic and stress-related conditions. However, aromatherapy is mainly used by people to create a sense of general well-being and a pleasant smell.
