Human mind is irritated by noise, bad smell, annoying things,
pollution etc. On the contrary, naturally occurring aromas do
the opposite.
Perfume enters lung and then goes to blood stream. When
applied directly on skin, it enters body through absorption.
Blood carries it to various parts of the body. Many aromatic
substances cross ‘Blood-brain-barrier’ and enter the central
nervous system (brain). It is where natural perfumes do
wonder.
It elevates a person’s mind to heavenly ecstasy. It is
anti-depressant and anti-anxiety. And so many positive things
start to appear.
Recent scientific studies suggest that the fragrances produce
immediate changes in physiological parameters such as blood
pressure, muscle tension, pupil dilation, skin temperature,
pulse rate and brain activity.
Measurement of brain activity by Electroencephalographic
response (EEG) reveals that natural perfume improves mental
condition.
Jasmine oil arouses change in brain waves that is associated
with the increase of positive emotions such as the feeling of
well-being, or feeling active, fresh and romantic. Sandalwood
oil causes changes in brain electrical wave which bring
soothing, calming and comforting effect.
