aromatherapy

Aromatherapy is a form of alternative medicine that uses volatile plant materials, known as essential oils, and other aromatic compounds for the purpose of altering a person's mood, cognitive function or health. The effectiveness of aromatherapy is yet to be scientifically proven, however some evidence exists that essential oils may have therapeutic potential.[1]

Since some essential oils such as tea tree[2] have demonstrated anti-microbial effects, it has been suggested that they may be useful for the treatment of infectious diseases. The evidence base for the efficacy of aromatherapy used to treat medical conditions remains poor with a particular paucity of methodologically rigorous studies
