The
Helichrysum Italicum essential oil is obtained by distilling,
usually by steam in a copper free steam process.
The Mediterranean Helichrysum is much richer in Terpenes has more
Neryle acetate and Diones. Helichrysum from countries other than
Corsica have also good therapeutic qualities for the human body.
In fact there are good comparisions that can be made with the
excellent and unique Helichrysum Italicum coming from Corsica
but from good distillers in the Balkans and Neryl Acetate is not
everything contrary to what a lot of people think and other factors
are equaly important
It
is true to say that content of Neryl Acetate
in the Immortelle coming from Corsica is higher and sometimes
it may account a large % content of the helichrysum oil. This
oil is added in small quantities, as an active ingredient, to
anti-wrinkle creams and other skin care products that contain
the natural helichrysum extracts.
Ketones
present in Helichrysum italicum essential oil aid quick skin regeneration.
They appear in larger proportions in helichrysum oils which have
been produced from the early shoots prior to flowering.
The group of molecules sesquiterpene hydrocarbons give helichrysum
oil: anti-inflammatory,anti-oxidant and anti-microbial properties.
One of the most impressive effects of helichrysum oil is how quickly
bruises, wounds and inflamed tissues are relieved, a further study
concludes that: "the anti-inflammatory activity of Helichrysum
italicum can be explained by multiple effects, including inflammatory
enzyme inhibition, free-radical scavenging activity and corticoid-like
effects".
Factors
Effecting Oil Quality
The composition of helichrysum oil will vary depending upon several
factors. The part of the plant which is harvested, the stage of
the life cycle and when it is harvested, which chemotype and genotype
has been grown and where geographically this was. This naturally
affects the properties of the extract. For example an Italian
study shows how plants from different areas can display large
variations in antioxidant and antifungal properties. Neryl acetate
is the constituent which varies most in quantity. It occurs more
when the helichrysum oil is produced from the flowers harvested
during full bloom.
Recent
studies have also shown that some plants native to both Italy
and Corsica can have in excess of 40% neryl acetate as the main
ingredient, but that others from areas nearby may have far less.
Further north the proportion of neryl acetate in Helichrysum italicum
essential oil is usually far lower, this may be for various reasons.
One suggestion made by Hadjikyriakou in his book, titled Aromatic
and Spicy Plants in Cyprus, is that the climate influences the
chemical composition and quality of the essential oils... [of]
aromatic and spicy plants. In this respect, the views of Theophratus
are illuminating:' ... the most excellent and fragrant of all
come from Asia and the sunny regions'.
Likewise
the fragrance, neryl acetate, can be found as larger fractions
in helichrysum oils produced in the southern sunny Mediterranean
regions. Despite this natural variation, the effects of helichrysum
oil are consistently remarkable. This is the nature of essential
oils and indeed life, each production is highly complex and unique.
Quoting from Katya et al, research scientists, from their study
which looked at bioactivity of essential oils.
Distilling
information.
Procedure:
Distilling is completed by water vapour.
Distilled parts: Flower heads mostly.
Botanical name: Helichrysum Italicum ssp serotinum
Country of origin: South of Europe, the Balkans & Corsica,
also known as “the island of beauty”
Quality: 100% pure and natural.
Visual aspect: A limpid, fluid liquid.
Its
natural combination of chemical constituents creates one of the
most profoundly healing essential oils available.
Today,
most common essential oils, such as lavender, peppermint, and
eucalyptus, are distilled. Raw plant material, consisting of the
flowers, leaves, wood, bark, roots, seeds, or peel, is put into
an alembic also known as a distillation apparatus and placed over
water. As the water is heated the steam passes through the harvested
plants, vaporizing the volatile compounds. The vapours flow through
a coil where they condense back to liquid, which is then collected
in the receiving vessel.
Most
oils are distilled in a single process. One exception is Ylang-ylang
(Cananga odorata), which takes 22 hours to complete through a
fractional distillation.
The
recondensed water is referred to as a hydrosol, hydrolat, herbal
distillate or plant water essence, which may be sold as another
fragrant product. The most common name for it is quite simply
floral water; it has the same proprieties as the essential oil
but in a less concentrated percentage. Popular hydrosols are rose
water, lavender water, lemon balm, clary sage and orange blossom
water. The use of herbal distillates in cosmetics is increasing.
Some plant hydrosols have unpleasant smells and are therefore
not sold. Such as Yarrow for example.
Note
on the Curry Plant : Although called "curry plant"
it has nothing whatsoever to do with the mixture
of spices used in Indian cooking, nor with the curry tree (Murraya
koenigii). It
has been claimed on some gardening forums that the curry plant
is as effective a cat deterrent as the "scaredy-cat"
plant, Plectranthus caninus (also known as Coleus canina). This
may be not so much a recommendation for Helichrysum italicum as
a comment on the efficacy of Plectranthus caninus.
Precautions
: The Helichrysum Italicum essential oil is non-toxic, non-irritant
and non-sensitizing, but should not however be used on children
under 12 years.
