Essential Oils Frequently Asked Questions
What does "essential"
mean?
Essence (from Latin "esse" = to be) has to
do with fragrance as essential part, as the nature of
a plant that carries its characteristics and information.
What are essential oils used
for?
- to aromatise the living area (creating atmosphere through
fragrances)
- as Feng Shui measures (to create a vital environment)
- at the office (for a clear head, to strengthen your
memory and for harmonious
surroundings)
- for home perfumery (to compose your individual natural
perfume)
- for the household (for cleaning, disinfection, aromatising)
- for aroma therapy (follow the instructions of your therapist)
- for aroma massage
- for aroma bathes and aroma sauna
- for aroma cosmetics (see dosage of essential oils)
- to stimulate sensuality (vive l'amour!)
- for foot care
- for aroma kitchen (see dosage of essential oils)
- for aroma culture ( to practise fragrance rituals and
the creative use of the oils)
- at school ( as playful method to stimulate creativity
and concentration)
- for subtle protection effect
How are essential oils obtained?
The most common way to obtain essential oils is steam
distillation. The three steps of distillation are: vaporization,
cooling and separation.
The plant material is carefully layered in the so-called
alambique. One method is to put the plant material directly
into the water and to boil the water.
The second method, that is more commonly used today, is
to put the plant material on a grid inside the alambique
and steam is drawn into it. The steam takes out the drops
of oil from the plant and carries them with it.
In a chilled tube the steam with the essential oil condenses
and is collected in a container, the Florentine pot. The
oil, in most cases lighter than water and therefore floating
on the surface, can now be separated from the water.
What does kbA mean?
(German: controlled biological cultivation) Organic cultivation
is based on integral thinking, agriculture/farming is
seen as an organism and as an interaction between soil,
plant, animal and human being. Ecological associations
as for example DEMETER, Nature & Progres and many
more are orientated to the rules of the worldwide association
IFOAM (International Federation of Organic Agricultural
Movement) and have laid down a multitude of guidelines
that are valid for organic cultivation:
Choice of plants appropriate to the site
Non-irrigated, little or only organically fertilized herb
plantations
Crop rotation
Ban of herbicides
Biological pest control
Increase of the natural soil fertility, e.g. through compost
Ban of genetic manipulated seeds
Renunciation of chemical-synthetic hormones, protective
substances for storage and after-ripening substances
What does top note, heart note,
base note mean?
Top notes describe lightly volatile fragrances that are
lasting only short time; their effect is cool, light,
fresh, invigorating; most of them enhance the concentration;
citrus oils for example have a clear top note.
Heart notes are flower oils such as Rose, Jasmine, Mimosa;
also woody-spicy scents are part of them; they all last
a little longer and with their harmonizing, balancing
but also sensually stimulating, aphrodisiac effect they
are the centre, the "heart" in a fragrant composition.
Base notes have a relaxing, stabilizing, grounding effect;
example: Vetiver; base notes are long lasting, heavy fragrances,
often from roots or resinous oils.
What are chemo types?
Chemo types are varieties inside a plant family (Rosemary,
Thyme) that contain a special characteristic ingredient
and therefore a special fragrance and effect. Examples:
Rosemary Verbenon, Rosemary Cineol, Thyme Thymol, Thyme
Linalol, Hyssop Decumbens.
How does cold pressing work?
To obtain the so-called citrus oils there are different
pressing methods:
1. The surface of the peel is carved; the raising essential
oil is sprayed off with water; afterwards oil and water
are separated by centrifuge.
2. After the juice is pressed from the citrus fruit the
left over peel is pressed and mixed with water, from this
oil-water-mixture the essential oil is obtained through
centrifuge.
What is the meaning of "Absolute"
and "Concrete"?
The word "Absolute" comes from the kind of obtaining
(Latin solvere = to solve).
Some of the precious flowers as Jasmine, Tuberose, Mimosa,
Broom and Narcissus can be neither obtained by steam distillation
nor by alcohol extraction. Nowadays mostly chemical solvents
as Hexane are used to extract the fragrant substances
out of the flowers.
With the first step one gets the ointment-like Concrete
that contains wax. One step further the solvent is distilled
with alcohol under vacuum - one gets the liquid or viscous
final product, the Absolute.
Absolutes are very intensive in their scent, only 1 -
2 drops are needed to blend with 50 ml basic oil.
What does Co-Distillation mean?
It's a special kind of distillation with surprising effects.
At the co-distillation (Latin: co = together) plants,
of which you normally can't get fragrance, are distilled
together with a vegetable carrying substance like rubber
plant or cedar. The carrying substance combines together
with the delicate scent of the distillation substance.
A joy for nosey noses: Nettle-Essence with the fragrance
of green leaves and warm summer soil; Alga-Essence - a
pinch of sea wind; Hay-Essence - scenting summer meadows.
What is enfleurage?
Enfleurage is a traditional method for gaining the scent
of very sensible plants. Flowers are laid by hand on a
sheet of glass that is coated with fat, then it's stored
in a dark and cool place. Afterwards the flowers are replaced
by new flowers. This procedure is repeated again and again
until the fat is saturated with essential oil and turned
into the so-called "pomade". Then the pomade
is washed with alcohol, in this way the fat is separated
and cleaned out from the essential oil. Afterwards the
alcohol is distilled and there is the pure essential oil.
How does Gas Chromatography
work?
In the gas chromatograph the different ingredients of
an essential oil are separated and classified. A carrying
gas transports a little bit of vaporized essential oil
through a column. The molecules of the different ingredients
get in order; each ingredient generates the so-called
"peak", a jagged swing of the graphic instrument
(comparable to ECG or EEG).
By this it's possible to state the quantity and quality
of the ingredients of an oil; by comparing recorded data
with the corresponding sample one can judge if the oil
is genuine and unadulterated.
The GC-MS (Gas Chromatography-Mass Spectographie) is a
combined method, that analyses the ingredients by their
molecular mass spectrum and facilitate an even more differentiated
quality judgement.
What is (((Enantiomerentrennung)))?
Plants have the quality of forming scent molecules in
a specific proportion of dextrorotatory and laevorotatory.
These so-called (((Enantiomerenverhältnisse))) are
measurable with a new analytic method, the so-called (((Enantiomerentrennung)));
they show whether an essential oil has been adulterated
or forged. Unfortunately with this method there are standards
only for a few oils, so it's not possible to have a control
for each oil and (((charge))).
How to measure out the oils
for the different applications?
Essential oils are concentrates: about 30 Damascene Rose
flowers give 1 drop of essential Rose oil. About 8 Million
Jasmine flowers come to 1 kg of Jasmine Absolute. In this
way the contents of one little bottle contains a concentrated
load of information and fragrance.
To add fragrance to a room you just put a few drops in
a diffuser - and you are walking through a citrus grove
or along the Copa Cabana. For aromatising rooms you have
the same rule as for natural cosmetic: less is more! Above
that many fragrances develop their bouquet and their richness
of nuances not until they are diluted. Tip: 1ml is about
25 - 30 drops of essential oil.
Dosage:
Adding fragrance to your room through a diffuser:
Let 1 - 10 drops essential oil evaporate with water (according
to the size of a room and the intensity of the oil: top
notes like citrus oils evaporate quickly; flower oils
like Jasmine and Narcissus scent strongly: here you need
just one drop).
Fragrant Fountain:
Add the most 10 drops essential oil a day.
To refresh yourself while travelling:
Put 1 - 2 drops essential oil on a tissue and inhale.
Face Oil:
5 - 10 drops in 100 ml Base Oil (Apricot Kernel, Jojoba,
Almond, Macadamia, Evening Primrose, Sallow Thorn or Rose
Hip Oil)
Body and Massage Oil:
10 - 25 drops in 100 ml Base Oil (Avocado, Hemp, Almond,
Jojoba, Sesame or Wheat Germ Oil)
Face Tonic
Mix 2 - 3 drops of essential oil with 100 ml Hydrosol
and 5 - 10 ml pure alcohol.
Perfume concentrations :
Eau de Cologne: 3 - 5 % perfume
Eau de Toilette : 4 - 8 % perfume
Eau de Parfum : 8 - 15 % perfume
Hot and cold compresses:
Put 2 - 6 drops of essential oil into 2 litres of water.
Face steam bath:
1 - 2 drops in 2 litres of water.
Face Masque:
Mix 3 tablespoons of clay, healing earth or oatmeal with
some water to a mush and add 2 - 4 drops of essential
oil.
Aroma Bath
Always mix the essential oils with emulsifiers, for example
2 - 3 tablespoons of PRIMAVERA LIFE Bath Oil "Basic",
cream, honey, liquid soap or sea salt.
Proper Bath: 10 - 20 drops of essential oil.
Hip Bath: 5 - 6 drops of essential oil.
Foot Bath: 5 - 6 drops of essential oil.
Sauna:
Put 3 - 5 drops of essential oil in one ladle of water;
stir it well (essential oils are easily flammable and
must not be evaporated undiluted).
Aroma Kitchen:
Blend 50 ml edible oil (olive, hazelnut or sesame oil)
with 3 - 5 drops of essential oil. Add the essential oils
after cooking. Never put the essential oils directly from
the bottle into the dish (danger of overdose!), but mix
before with an emulsifier.
Sweet emulsifiers: Cream, honey, maple syrup, nut-butter,
and fructose
Salty, piquant emulsifiers: Vegetable oils like olive,
sunflower, safflower; sea salt, vinegar, soybean sauce,
mustard, egg yolk
Household:
Clean rooms with 5 - 10 drops essential oil in 5 litres
of water.
Where does the word "Aromatherapy"
come from?
The term "Aromatherapy" dates from the year
1928 from the French chemist René-Maurice Gattefossé
who was working with the antibiotic and antiseptic qualities
of essential oils.
How do we absorb essential oils?
1. Through the nose
Here the fine scent molecules are taken inside the olfactory
mucous membrane. From there electrical impulses are sent
to the brain, affecting both body functions and emotions.
2. Through the skin
During applications as for example aroma massages or aroma
baths it's not only the olfactory sense that is stimulated,
but also parts of the essential oils are absorbed through
the skin and get into blood circulation.
3. Internal use
For a novice it's not advisable to take essential oils
internally, as they are extremely irritating to mucous
membranes. Use internally only after consulting a physician.
Do essential oils have an aphrodisiac
effect?
Love and Eros live out of certain moods, of magic and
atmosphere. More subtle and mostly unconscious scents
have a major role. Activating imagination, fragrances
and perfumes attract, draw attention and - leed you by
the nose. The erotic effects of scents, however, are individually
different.
Spice notes as Pepper, Clove Leaves or Cardamom "fire"
the senses. Flower oils like Rose or Neroli may give a
sensuous mood as they have a relaxing effect. Oils like
Jasmine or clary sage make euphoric, exhilarate and inspire.
Especially heart and base notes that last longer and have
a scent fixing effect belong to the aphrodisiac fragrances:
Carnation, Ylang Ylang, Rose, Champaca, Jasmine, Frangipani,
Acacia, Rose Geranium, Labdanum, Patchouli, Sandalwood,
Cedar, Oud, Vetiver, Benzoin.
Apply your favourite scent (blended in a base oil) to
your skin and to the inside of your clothes, to earlobes,
hair (that is an excellent carrier for scents) and everywhere
else, where the blood pulses directly under the skin,
like to the inside of the forearm, the wrist and the (pounding)
heart.
Attention with allergies
Nowadays many people react to different substances with
allergic reactions. Essential oils are highly concentrated
substances and therefore can cause allergic reactions
to sensitive persons. It is worth testing your favourite
scent before using it for body care. Blend 1 drop essential
oil with about 10 drops base oil, e.g. almond oil, and
apply to the inside of your forearm. If skin turns red,
please abstain from this essential oil.
How do sun and essential oils
go together?
Some essential oils raise the photosensitivity of skin:
Angelica Root, Bergamot, Bitter Orange, Clementine, Grapefruit,
Lime, Mandarin, Orange, and Lemon. After an application
of one of these oils (perfume, body oil or massage oil)
you shouldn't use the solarium nor expose your skin to
the sun.
How many scents can one person
distinguish?
It is theoretical possible for one person to distinguish
some thousands of different scents. It depends on many
conditions, how fine and distinctive the olfactory sense
is: mood, well-being, state of mind, age, sex, menstruation
cycle, smoking habits - and training. The more you sniff,
smell and perceive consciously, the more you will make
distinctions between the scents and will be able to classify
them.
Where do plants store essential
oil?
Essential oils are produced and stored by different parts
of the plants. Nearly all the parts of a plant can contain
essential oils. Depending on their nature, the plants
store them in different containers: many labiates, as
Sage, Melissa or Marjoram have gland hair or gland scales
in their upper skin layer.
Laurel plants such as Cinnamon or Cassia have oil- and
resin-cells to store their fragrant fluids.
In many umbellifers like Aniseed, Fennel and Coriander
the essential oils are situated in tubular ducts that
give off oil only after being cut or broken.
When peeling a citrus fruit the fragrant essence splashes
onto us. The plant stores the oil in cavities, the oil
containers, they can be easily identified with the naked
eye on the peel.
How much oil is contained in
fragrant plants?
The content of oil in fragrant plants differs between
0,001% and up to 20% (clove).
For example: 100 kg plant material come to the following
amounts of essential oil:
2,1 kg Lavendin, 0,4 kg Rosemary, 0,1 kg Hyssop, 0,3 kg
Sage, 0,012 kg Melissa.
Why don't essential oils always
smell the same?
Plants need very specific conditions concerning climate,
locality and weather to produce their fragrant substances
to their perfection: quality of soil, local rain fall,
mild or rough climate, frost and especially sunny days
have an effect on content, quality and fragrance character
of the essential oils. In this way it's possible that
the scent of an essential oil varies from year to year
as it is known with wine. Only standardized industry oils,
that are very often subsequent treated and "adjusted"
to a fixed value of contents, always smell the same.
What are fixatives?
These are agents that fix other scents. They are used
to bind lightly volatile fragrances in perfume compositions.
To compose a harmonic course of a perfume - i.e. the single
fragrant components (top-, heart and base-notes) are perceived
at different moments - one uses fixatives that are a kind
of "anchor" for the fragrances. Vegetable fixatives
are for example Musk Mallow, Styrax, Benzoin, Sandalwood
and Vetiver.
What is Ambergris?
Ambergris is an excretion of the whale (Physeter macrocephalus).
This giant of the ocean from time to time spits out a
stomach secretion formed as black or grey clods. Those
are washed ashore and are traded as very demanded fragrance.
Through exploiting whale-hunting and pollution of the
oceans the whales are decimated and the ambergris is an
unaffordable rarity.
What does (((anosmy))) mean?
It means olfactory blindness of a person, i.e. the inability
to perceive scents and to smell.
What is a Hydrosol?
Hydrosols are aromatic floral waters obtained from steam
distillation of essential oils. During the distillation
the steam dissolves the essential oil off the plant material.
After cooling and condensing the essential oil floats
on the aromatic water and can be easily separated. The
water has gone through the whole process of distillation
and is saturated with essential oil and the information
of the plant (content of essential oil between 0,1 and
0,5 %).
