University of Manchester researchers found three of the oils,
usually used in aromatherapy, destroyed MRSA and E.coli bacteria in
two minutes.
They suggest the oils could be blended into soaps and shampoos
which could be used in hospitals to stop the spread of the superbug.
Hospital-acquired infections, such as MRSA, kill an estimated
5,000 a year.
They wanted to ensure they could not harm the patients, whose
immune systems are weakened by the treatments.
Dr Peter Warn, who carried out the research, said: "When I
tested the oils in the lab, absolutely nothing grew. Rather than
stimulating bacteria and fungi, the oils killed them off."
Soaps and shampoos
The team then tested 40 essential oils against 10 of the most
infectious agents found in hospitals, including MRSA (methicillin-resistant
staphylococcus aureus).
Two of the oils were found to kill MRSA and E.coli almost
instantly, while a third was found to act over a longer period
of time.
However, the researchers say they are unable to reveal which
oils carry benefits because of commercial sensitivities.
MRSA is often carried in patients' nostrils, and is currently
treated by putting disinfectant on the area to kill the
bacterium - which many patients often find unpleasant.
Dr Warn says the essential oils could be used to create much
more pleasant inhalation therapies - which he said were likely
to have a much higher success rate than the current treatment,
which is only effective in around 50% of cases."

Dr Warn said: "We believe that our discovery could
revolutionise the fight to combat MRSA and other superbugs."
But he said the team now needed around £30,000 in order to
continue its research.
Jacqui Stringer, clinical leader of complementary therapies
at Christie Hospital in Manchester, instigated the oils
research.
She said: "Our research shows a very practical application
which could be of enormous benefit to the NHS and its patients.
"The reason essential oils are so effective is because they
are made up of a complex mixture of chemical compounds which the
MRSA and other superbug bacteria finds difficult to resist."
The Department of Health evaluates products which are claimed
to prevent or treat HAIs before it permits them to be used
across the NHS.
