Aromatherapy is a type of alternative medicine that uses the part of plants known as essential oils. Some people think that aromatherapy helps to change a person's mind, mood or health but this has not been proven scientifically.
Some essential oils like tea tree[1] do have an anti-microbial effect, so they may be useful for the treatment of infections. Evidence that aromatherapy works in treating disease and other conditions is poor.[2]
