Ancient minty painkiller worked, study suggests

Ancient Chinese used mint oil, which has anti-inflammatory properties

The doctors of ancient Greece and China had it right when they applied cool and

minty salves to soothe aches and pains, a new study suggests.

 

A synthetic treatment with the same properties as mint oil is an effective

painkiller when applied directly to the skin. The new cooling compounds could be

especially beneficial to millions suffering with the chronic pain of arthritis

and diseases affecting nerve endings, scientists say.

 

" They work particularly well in ongoing pain states where the nervous system

becomes hypersensitive so even the lightest touch becomes painful, " said study

leader Susan Fleetwood-Walker, a professor of neuroscience at the University of

Edinburgh.

 

Healers in ancient Chinese societies treated injuries with mint oil, which

contains anti-inflammatory properties and produces a cooling effect on the skin.

 

Cold compresses were also recommended in the fifth century BC by Hippocrates,

who is considered the father of modern medicine. Swelling and joint pain could

be eased by the numbing effect of copious amounts of cold water, the ancient

Greek scholar said.

 

The new compounds use the same soothing chemicals found in mint oil, but

incorporate a few other important elements that work specifically with a pain

receptor nerve in the skin called TRTM8, newly discovered by Fleetwood-Walker

and her team.

 

" Chemicals in mint oil and cooling the skin can activate these painkilling

nerves but neither traditional method is very specific, " she told LiveScience.

" We have shown that the TRTM8 receptor is the critical molecular target for this

pain killing effect. "

 

Special analgesic ingredients in the compounds - telling the receptor to turn

off pain messages going to the brain - make them even more effective, the

results showed.

 

Fewer side-effects

The minty formula offers significant advantages versus some other pain

medications, which do not always work on sufferers of long-term pain, say the

researchers.

 

" Some types of chronic pain, especially following nerve injury, are resistant to

morphine, " Fleetwood-Walker said. " These compounds act powerfully as pain

killers on many types of chronic pain including nerve injury pain. "

 

Because the compounds are applied externally, they should also come with a

shorter list of potential adverse reactions, she said. " They seem to be just as

powerful as morphine, but work through an entirely separate mechanism, with what

we think will be less side effects.

 

The findings appear in an August issue of the journal Current Biology.
