Aromatherapy oils. Assortment of aromatherapy oils in a glass cabinet. From left to right they are: (at top) eucalyptus (two oils), camomile and rose, and (at bottom) jasmine, tea tree, sandalwood and lavender (two oils). 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 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.
