A rosemary plant on your desk could improve your work performance and how
you feel about it. The old saying "rosemary is for remembrance" seems true.
Smelling the herb produces beta brain waves which demonstrate alertness.
The link between smelling rosemary and scoring higher on mental tests was
established by Dr Moss in 2003. However, more surprising news was to come.
The more of the compound in the bloodstream the more cognitive performance
Several studies demonstrate that the smell of lemons can reduce stress at
least in rodents.
In one investigation the technical research centre at the Japanese flavour
and fragrance company T Hasegawa gave stressed lab rats linalool, a
component of lemons.
The researchers say their findings could form the basis of new blood tests
for identifying stress-busting fragrances. At the Institute of Pharmacology
in Tübingen, Germany, mice that became active after exposure to oils of
rosemary and dwarf pine calmed down with oils of lemon balm and valerian.
The sweet white flowers could be nature's Valium. Researchers at Ruhr
University led by Prof Hatt found that brains can respond as well to jasmine
as to sedatives and barbiturates.
Tests showed jasmine dramatically calmed mice when their cage was filled
with it. Brain scans confirmed this. By changing the chemical structure of
the scent molecules researchers hope to achieve even stronger effects.
Jasmine soothes, promotes high quality sleep and relieves anxiety.
Dr Hirsh says jasmine also helps to improve hand-eye coordination in cases
as diverse as classical violinists and doctors performing
