Scent of vanilla helps to ease pain: Japanese researchers
Japan Today -- Jul 13
The aroma of vanilla extract can help to ease muscle pain and tension and may eventually factor into a treatment for stress headaches, a team of Japanese researchers has concluded.

The team from Kawasaki University of Medical Welfare in Okayama Prefecture, western Japan, recently discovered the pain-relieving effects of vanillin, a key element of vanilla, in an experiment using mice.

Although the scent of vanilla has long been used in aromatherapy to induce relaxation, it had not previously been confirmed through scientific study to affect the nervous system, the team said.

According to the group, the experiment involved administering vanillin to mice and then putting them on a board heated to around 55 C. Mice that had inhaled vanillin took two seconds longer before leaving their forepaws due to the heat than those which had not received a dose of the agent.
