What
are Essential Oils?
Essential
oils are the concentrated, pure essence of plants. These essential
oils are extracted from various parts of the plant, such as the
stems, flowers, leaves, bark, and roots. They are appealing to our
senses and extremely aromatic, thus leading to their frequent use
in fragrances and perfumes. Aromatic plants have been used for many
centuries, with evidence dating back 4,000 years ago to the ancient
Sumerians.
Priests
in many ancient cultures utilized ground herbs infused in oil to
heal their patients. This led to the field of Aromatherapy, which
literally means "healing through the senses". Today, Aromatherapy
can be defined as the controlled use of essential oils to maintain
and promote physical, psychological and spiritual well-being. One
method is to blend the essential oils in a carrier solution and
anoint the body with a personal blend for healing. The extraction
method of how to create essential oils has evolved over time. Some
of these are listed below.
Essential
oils are exclusively utilized in the blending of all of our soaps
and in the creation of our personal blends. Organic essential oils
are preferred when they are available from the distributors. The
essential oils come from many regions around the world, bringing
the rich heritage and history of their country of origin.
Extraction
Methods:
Steam
Distilled is the most commonly used method to refine essential
oils. This involves placing the plant in a pressurized, steamed
chamber. As the pressurized steam enters the plant it ruptures the
oil-bearing sacs, liberating and vaporizing the essential oil. The
steam and vaporized oil are then condensed. Subsequently, the essential
oil floats to the top of the water and is harvested. Essential oils
are actually not oil, but they are called this because their light
density allows them to float on top of the water as oil normally
would.
The
small quantity of water remaining after harvesting the essential
oil does contain aromatic particles and is called fragrant water
or hydrosols. Hydrosols also have many beneficial uses. Rose water,
which has been used for centuries for nurturing the integrity of
the skin, is one example of a floral hydrosol.
Cold-Pressing
is a gentle process used for extracting the essential oils from
the citrus rind of fruits such as lime, bergamot, orange, grapefruit,
and others. The outer layer of the peel is ruptured by mechanical
means and the essence of the fruit is expelled. Steam-distilled
and cold-pressing are the preferred extraction methods of essential
oils because the purity of harvesting maximizes the therapeutic
benefits.
Effleurage
is a process used on plants that have a very low concentration of
essential oils or on delicate flowered plants such as Jasmine, Rose,
Neroli, Tuberose, and others. Fat substances are used to extract
the plant essence and this is followed by a treatment with alcohol
which produces a substance called an absolute. This process is very
expensive and thus not widely used.
