Essential
oils are the fragrant chemical substances extracted
from various parts of plants: flowers, fruits,
roots, leaves and stems.
Some
oils have stimulating effect on the body, mind
and emotions, whereas others have a calming influence.
They are all antiseptic; some have powerful antiviral
or antifungal properties, some antidepressant,
digestive, analgesic
the list of properties
is long!
Where
do they come from?
In most instances essential oils are obtained
by traditional, and probably the oldest, method
- distillation of raw plant material: flowers,
leaves, seeds, twigs, fruits, tree raisin, etc.
Other methods are: enfleurage, maceration, expression
and solvent extraction.
The quality of an essential oil is influenced
by a number of factors, particularly its geographical
and botanical source, the prevailing climate,
farming methods, the time of harvesting and subsequent
treatment.
As
the demand for essential oils from food and cosmetic
industry is so great, synthetic 'equivalents'
of some essential oils or their ingredients are
produced for these industries benefit. Each industry
that uses essential oils has different criteria
in terms of the quality. In aromatherapy, the
'whole' essential oil in its purest form is used
to achieve an overall therapeutic effect. This
is because the human body appears to tolerate
natural substances a lot better than synthetics,
there will be fewer side effects and the body
will not build sensitivity as it often does with
synthetic drugs. In view of that it is wise to
obtain oils from specialist shops and reputable
suppliers who are able to proof quality and purity
of their products.
