Aromatherapy oils. Bottles containing aromatherapy oil seen with an aromatherapy burner (at left). Aromatherapy oils are made from fragrant herb and flower extracts (essential oils) suspended in a neutral carrier oil. The oil releases the volatile plant extracts into the air as it is warmed in a heater or massaged into the skin. 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.
