Essential oils. ( Part Two)



While the scent is nice to have in the air, essential oils benefit you the most when they get into your bloodstream. They re-establish harmony, revitalize systems and organs where there is a malfunction or lack of balance. They boost the immune system, making it strong enough to fight off the diseases attacking every day. Essential oils balance emotions, to some degree. They help revive a tired mind and stimulate memory.  Different fragrances of essential oils will relax, revitalize or renew your mind, body and soul.

** WARNING: Never use a fake essential oil or perfume oil, see my post: Essential oils. ( Part One) for details.

~Essential oils are absorbed into the body a couple of ways:
  1. When massaged into the skin, essential oils are absorbed into the hair follicles and mix with sebum at the base. They are then diffused into the bloodstream.

  2. When the scent is inhaled, it enters the nose, moves to the lining of the lungs and is quickly absorbed into the bloodstream.

~Here is a helpful list of all pure essential oils and their properties:

-Allspice Berry- The oil has a warm, spicy-sweet aroma. It is used in spicy or masculine scents. It combines well with orange, ginger, patchouli and all of the spice oils including cinnamon, cassia and clove. Aromatherapy benefits: warming, cheering, comforting, nurturing.


- Amyris is also known as West Indian sandalwood, although unrelated to the true Indian sandalwood. It has a woody, slightly sweet, balsamic aroma, suggestive of sandalwood. Amyris is used as a fragrance fixative-it slows the evaporation and dissipation of the fragrance it is added to. It blends well with cedarwood, jasmine and rose scents. Aromatherapy benefits: strengthening, centering.


- Anise and star anise are often used and sold interchangeably because they are similar in aroma and chemical make-up. he primary constituent of both is anethole, a sweet substance that solidifies at room temperature. If this happens simply warm the bottle in a warm water bath until the oil liquefies. Aromatherapy benefits: cheering, mildly euphoric.


-Basil, Sweet : There are many types of basil: linalool basil, exotic basil and sweet basil. The odor of the linalool type is very green, floral-sweet and is most often used in expensive perfumes. The exotic type of basil is stronger with a hint of camphor. Frontier's sweet basil type combines both qualities in a floral-spicy aroma with a lasting herbal sweetness. Clary sage, bergamot and lime oil work well with basil oil. Aromatherapy benefits: clarifying, uplifting, energizing, refreshing.


- Bay oil is distilled from the leaves and small twigs of the bay rum tree. It has a powerful, spicy, sweet aroma with a distinctive clove note. It is used to produce bay rum fragrance and as a component of fresh, spicy scents. Aromatherapy benefits: clarifying, warming.


— Bergamot oil is cold-pressed from the peel of the nearly ripe fruit. The aroma of bergamot oil is fresh, lively, fruity and sweet. It is an excellent deodorizer. It contains a constituent called bergaptene that increases the skin's sensitivity to sunlight. Bergamot BF means "bergaptene free." Most of the sensitizing bergaptene constituent has been distilled out of this product but traces may still remain. Aromatherapy benefits: uplifting, inspiring, confidence-building.


- Camphor is the grade preferred in scenting detergents, soaps, disinfectants, deodorants, room sprays and other household products. Aromatherapy benefits: clarifying, energizing, purifying.


- Cardamom oil has a spicy, camphor-like aroma with floral undertones. It imparts a warm note to masculine scents and floral perfumes. It blends well with bergamot, frankincense, ylang ylang, cedarwood and coriander. Aromatherapy benefits: warming, comforting, alluring.

- Carrot seed oil is distilled from the seed of the common carrot. Its aroma is dry-woody, somewhat sweet and earthy. In perfumery, carrot seed oil is appreciated for the interesting fatty-woody note it lends to Oriental, fantasy, and nature-type perfumes. It is an excellent addition to skin care oils. Aromatherapy benefits: replenishing, nourishing, restoring.

- Cassia, or Chinese cinnamon, is the spice sold as cinnamon in the United States. Ceylon cinnamon (Cinnamomum zeylanicum) is considered the true cinnamon in most of the rest of the world. The two are similar in taste, though Ceylon cinnamon has a sweeter, more delicate flavor. The oils of both contain cinnamic aldehyde as the major component, with cassia having the larger amount. Caution: Cassia oil is very irritating to the skin and should be handled with care. Aromatherapy benefits: comforting, energizing, warming.


- Cedar grows in the Atlas Mountains of Morocco and Algeria. The aroma of Atlas cedar is woody, oily and slightly animal-like. The tree is closely related to the famous centuries-old biblical cedars of Lebanon now protected from further destruction by law. Atlas cedar is used for its aroma and fixative powers in soaps and perfumes. It blends well with woody, floral fragrances. Aromatherapy benefits: stabilizing, centering, strengthening.


-Cedarwood, Red - Red cedarwood essential oil actually comes from a type of juniper known as Juniperus virginiana, whose common name is eastern red cedar. The balsamic-woody aroma of cedarwood oil evokes a feeling of inner strength and centeredness. It is quite useful in times of emotional stress and anxiety to overcome feelings of powerlessness.


- German chamomile is also known as blue chamomile. The color of the oil is deep blue, turning green then brown with age and exposure to light. The odor is sweet, tobacco-like and fruity, apple-like. It adds a warm, long-lasting, rich undertone in perfumes. Chamomile is a mild, soothing oil and is popular in massage blends and other herbal preparations. Aromatherapy benefits: calming, relaxing, soothing.


- Roman chamomile contains only trace amounts of the intense blue component azulene, which gives German chamomile its color. This oil is commonly used in perfumery. It blends well with bergamot, jasmine, neroli and clary sage, lending a warm, fresh note when added in small quantities. The aroma is not long-lasting like that of the German chamomile but it is a mild, soothing oil. Aromatherapy benefits: relaxing, calming.


- Wild or Moroccan chamomile is related to Roman chamomile. While the fragrance of these two are somewhat similar, wild chamomile is distinct enough to have earned its own place in perfumery. Wild chamomile has a fresh, herbal note and a rich, balsamic, sweet undertone which is very long-lasting. It blends well with woody fragrances like cypress, as well as citrus oils and musk scents like angelica. Aromatherapy benefits: soothing, nurturing.


-  Ceylon cinnamon, this is the true cinnamon of world commerce. Its aroma is similar to cassia, or Chinese cinnamon. The aroma of Ceylon cinnamon is preferred to cassia for perfume where it gives a warm, floral-enhancing effect. Cinnamon oil blends well with oriental-woody notes and is often combined with frankincense. It is a skin irritant and should be handled with care. Aromatherapy benefits: comforting, warming.


- Cinnamon leaf oil is distilled from the leaves of the same tree that produces cinnamon bark oil. The aroma is more reminiscent of cloves than cinnamon due to the large amount of eugenol in the oil. It is often used in Oriental fragrances. Use with care, cinnamon leaf can irritate the skin. Aromatherapy benefits: refreshing, vitalizing.


- Citronella: There are two types of citronella: the Java type and the Ceylon type. The Ceylon type. While the grass that produces the Java oil is grown in many parts of the tropical world, the Ceylon type is cultivated in Sri Lanka. The oils produced from the two types of grasses vary somewhat in composition, aroma and flavor. The odor of Ceylon citronella is fresh, grassy and warm-woody. It is preferred for scenting outdoor sprays, room sprays and household products. Java oil has a sweeter, more floral aroma which is preferred in perfumery. Aromatherapy benefits: purifying, vitalizing.

- Clary sage oil has a spicy, hay-like, bittersweet aroma. It combines well with coriander, cardamom, citrus oils, sandalwood, cedarwood, geranium and lavandin. The aroma of clary sage is long-lasting and the oil is valued as a fixative for other scents. Aromatherapy benefits: centering, euphoric, visualizing.


- Clove oil is distilled from the whole dried flower buds of the clove tree. Inferior oils are distilled from the leaves and stems and are sometimes sold as clove oil without any designation of the source. Clove bud oil has a powerful, spicy-fruity, warm, sweet aroma. Clove oil is highly irritating to the skin and should be handled with caution. Aromatherapy benefits: warming, comforting.

-Nutmeg - Nutmeg oil is distilled from whole, dried nutmegs that have been cut into small particles and pressed to remove the fixed oil, also known as nutmeg butter. The oil has the characteristic aromatic, volatile, oily-spicy fragrance of whole nutmegs. Nutmeg oil is a component in men's fragrances and spicy perfumes. Aromatherapy benefits: rejuvenating, uplifting, energizing.

-Orange, Mandarin - Although the botanical differences between mandarin and tangerine are slight, the oils expressed from each differ in aroma and are not considered interchangeable in aromatherapy. The floral, neroli-like undertones of mandarin are evocative and sensual. Mandarin is used in combination with other citrus oils in colognes and fantasy-type perfumes. (See Tangerine.) Aromatherapy benefits: uplifting, cheering, sensual.

-Orange, Sweet - More sweet orange oil is produced than any other citrus oil. Two kinds of sweet orange oil are available: distilled or expressed. Distilled oil is a byproduct of juice making and has an inferior aroma. It is often used as an adulterant in expressed or pressed oil. Our oil is pressed from the peels of ripe, sweet oranges. It has a lively, fruity, sweet aroma. It is used to scent fruity and eau de cologne fragrances. All citrus oils are quick to deteriorate and should be stored in a cool, dry, dark area in full containers. Aromatherapy benefits: cheering, refreshing, uplifting.

Essential oils. ( Part one)






~What is an essential oil and How to avoid buying a low quality product.~


Most commonly, the essence is extracted from the plant using an technique called distillation. One type of distillation places the plants or flowers on a screen. Steam is passed through the area and becomes "charged" with the essence. The steam then passes through an area where it cools and condenses. This mixture of water and essential oil is separated and bottled. Since plants contain such a small amount of this precious oil, several hundred pounds may needed to produce a single ounce.

Steam Distillation

Steam distillation is the most common method of extracting essential oils. Many old-time distillers favor this method for most oils, and say that none of the newer methods produces better quality oils. Steam distillation is done in a still. Fresh, or sometimes dried, botanical material is placed in the plant chamber of the still, and pressurized steam is generated in a separate chamber and circulated through the plant material. The heat of the steam forces the tiny intercellular pockets that hold the essential oils to open and release them. The temperature of the steam must be high enough to open the pouches, yet not so high that it destroys the plants or burns the essential oils. As they are released, the tiny droplets of essential oil evaporate and, together with the steam molecules, travel through a tube into the still's condensation chamber. As the steam cools, it condenses into water. The essential oil forms a film on the surface of the water. To separate the essential oil from the water, the film is then decanted or skimmed off the top. The remaining water, a byproduct of distillation, is called floral water, distillate, or hydrosol. It retains many of the therapeutic properties of the plant, making it valuable in skin care for facial mists and toners. In certain situations, floral water may be preferable to pure essential oil, such as when treating a sensitive individual or a child, or when a more diluted treatment is required.

Cold Pressing

Another method of extracting essential oils is cold-pressed expression, or scarification. It is used to obtain citrus fruit oils such as bergamot, grapefruit, lemon, lime, mandarin, orange, and tangerine oils. In this process, fruit rolls over a trough with sharp projections that penetrate the peel. This pierces the tiny pouches containing the essential oil. Then the whole fruit is pressed to squeeze the juice from the pulp and to release the essential oil from the pouches. The essential oil rises to the surface of the juice and is separated from the juice by centrifugation.

Enfleurage
Some flowers, such as jasmine or tuberose, have such low contents of essential oil or are so delicate that heating them would destroy the blossoms before releasing the essential oils. In such cases, an expensive and lengthy process called enfleurage is sometimes used to remove the essential oils. Flower petals are placed on trays of odorless vegetable or animal fat, which will absorb the flowers' essential oils. Every day or every few hours, after the vegetable or fat has absorbed as much of the essential oil as possible, the depleted petals are removed and replaced with fresh ones. This procedure continues until the fat or oil becomes saturated with the essential oil. Adding alcohol to this enfleurage mixture separates the essential oil from the fatty substance. Afterwards, the alcohol evaporates and only the essential oil remains.

Solvent Extraction
Another method of extraction used on delicate plants is solvent extraction, which yields a higher amount of essential oil at a lower cost. In this process, a chemical solvent such as hexane is used to saturate the plant material and pull out the aromatic compounds. This renders a substance called a concrete. The concrete can then be dissolved in alcohol to remove the solvent. When the alcohol evaporates, an absolute remains. Although more cost-efficient than enfleurage, solvent extraction has disadvantages. Residues of the solvent may remain in the absolute and can cause side effects. While absolutes or concretes may be fine for fragrances or perfumes, they are not especially desirable for skin care applications. Some trees, such as benzoin, frankincense, and myrrh, exude aromatic 'tears', or sap that is too thick to use easily in aromatherapy. In these cases, a resin or essential oil can be extracted from the tears with alcohol or a solvent such as hexane. This renders a resin or an essential oil that is easier to use. However, only those oils or resin extracted with alcohol should be used for aromatherapy purposes.

Turbo Distillation Extraction
Turbo distillation is suitable for hard-to-extract or coarse plant material, such as bark, roots, and seeds. In this process, the plants soak in water and steam is circulated through this plant and water mixture. Throughout the entire process, the same water is continually recycled through the plant material. This method allows faster extraction of essential oils from hard-to-extract plant materials.

Hydrodiffusion Extraction
In the hydrodiffusion process, steam at atmospheric pressure is dispersed through the plant material from the top of the plant chamber. In this way the steam can saturate the plants more evenly and in less time than with steam distillation. This method is also less harsh than steam distillation and the resulting essential oils smell much more like the original plant.

Carbon Dioxide Extraction
Supercritical carbon dioxide extraction uses carbon dioxide under extremely high pressure to extract essential oils. Plants are placed in a stainless steel tank and, as carbon dioxide is injected into the tank, pressure inside the tank builds. Under high pressure, the carbon dioxide turns into a liquid and acts as a solvent to extract the essential oils from the plants. When the pressure is decreased, the carbon dioxide returns to a gaseous state, leaving no residues behind. Many carbon dioxide extractions have fresher, cleaner, and crisper aromas than steam-distilled essential oils, and they smell more similar to the living plants. Scientific studies show that carbon dioxide extraction produces essential oils that are very potent and have great therapeutic benefits. This extraction method uses lower temperatures than steam distillation, making it more gentle on the plants. It produces higher yields and makes some materials, especially gums and resins, easier to handle. Many essential oils that cannot be extracted by steam distillation are obtainable with carbon dioxide extraction. In the future, many botanicals that are not now available may possibly be obtained through carbon dioxide extraction.

~There are many variables that make qualify the quality of a specific essential oil. The plant it's derived from, if it was organic, if the soil is not right or the extraction method all factor into quality

 
~How to spot and avoid buying fake essential oils:

Anyone selling essential oils should disclose its quality or if it synthetic. Of course synthetic oils do not have the same properties or affects as their natural and real counterparts.  Many believe that use of the synthetic essential oils does actually increase toxicity and its not really recommended.

As most know, essential oils should be stored in dark glass container. Oils can range from $5 - $30 per bottle depending on the quality of the product. One way to spot less than perfect essential oils is wide varieties as the same price.

Next don't fall for the perfume or fragrance label. Chance are that means there is no essential oil found in the fragrance of the perfume. They are our synthetic friends yet again. Basically you will find a lot of imposters on the market these days. But most of all if you are interest into the healing benefits of the essential oils you, you will find that the synthetic just doesn't hold up to the test.

There are many tests you can do to see if the oils are real. But no test will take the place of experience where as you will learn over time how to spot that fake. There are very expensive test that can be ordered or you can consider placing a drop of the oil on a piece of construction paper. Because of how a pure oil will react it will evaporate quickly and will not leave a ring. Oils that are not pure or synthetic will leave an oily ring on the paper, clearly marking it as a fake.
