How do they work?
Aromatherapy uses the sense of smell, and simply by smelling
an oil an olfactory response is elicited. Smell is the least understood of the five senses, and yet it is perhaps the most
powerful.
The
olfactory membrane is the only place in the human body where the central nervous system is exposed to the outside environment.
Upon smelling an aroma, an impulse travels along the olfactory nerve directly to the limbic part of the brain. The limbic
brain is responsible for evoking memory, emotions, hunger response and sexual arousal. Before we consciously know that we
are in contact with an aroma, our subconscious mind has already received it and reacted to it.
On the level of the emotions, essential
oils can be uplifting, soothing, stimulating, refreshing, and calming. An article in the British medical journal Lancet reported
that patients suffering from insomnia fell asleep more quickly when exposed to lavender aroma.
The Memorial Sloan Kettering
Cancer Center has also experimented with aromatherapy on patients undergoing Magnetic Resonance Imaging (MRI). Those patients
who complained of claustrophobia, while spending an hour in the magnetic capsule, felt less anxiety and discomfort when the
aroma of vanilla was introduced.
Aromatherapy is just as effective in healing the body. The molecular structure of an
essential oil is tiny, which allows it to pass through the skin and directly into the bloodstream where it can affect the
organs and other body systems.
For instance, massage oil with Geranium Rose balances hormones
and relieves fluid retention, in addition to relieving anxiety, depression and stress. Rosemary stimulates circulation particularly
in those who have chronically cold hands and feet, and peppermint aids in digestion.
