Q: What is aromatherapy and what is it good for? - Layperson

A: Aromatherapy is derived from the ancient practice of using natural plant essences to promote health and wellbeing. It consists of the use of pure essential oils( volatile oils that occur in plants and in general give to the plants their characteristic odors, flavors, or other such properties. Essential oils are found in various parts of the plant body (in the seeds, flowers, bark, or leaves) and are also concentrated in certain special cells or groups of cells (glands). Because of their properties, they are widely used in perfumes, flavorings, and medicines. Their chemical composition differs: A great many, for example, are principally terpenes, compounds of carbon and hydrogen. Others contain aldehydes, ketones, or phenols. Oxygen, sulfur, and nitrogen are present in compounds in others. In general, they are complex mixtures. They are obtained from the plant in various ways, depending upon the nature of the part in which they occur; by compression, by distillation with steam, by dissolving the oils out (extraction) or absorbing them, and by pressure and maceration. Among the plants notable for their essential oils are members of the following plant families: carrot (e.g., anise, dill, angelica), ginger (cardamom), heath (wintergreen), laurel (cinnamon and camphor), mint (pennyroyal, peppermint, spearmint, thyme), myrtle (clove and eucalyptus), olive (jasmine and lilac), orchid (vanilla), pulse (acacia and sweet pea), rose (attar of roses and almond), and rue (lemon and other citrus plants).) obtained from a wide assortment of plants, which have been steam distilled or cold-pressed from flowers, fruit, bark and roots.

Aromatherapy can help ease a wide assortment of ailments; easing aches, pains, and injuries, while relieving the discomforts of many health problems.

Aromatherapy also acts on the central nervous system, relieving depression and anxiety, reducing stress, relaxing, uplifting, sedating or stimulating, restoring both physical and emotional wellbeing.  The following is a partial list of common essential oils:

Methods of Extracting Essential Oils

I'd like to thank Ben Alkire (Contact Ben to see his home distillation kits if you want to produce your own essential oils and hydrosols) and Christopher McMahon of White Lotus Aromatics for providing much of the information below.
 

Distillation:

The vast majority of true essential oils are produced by distillation. There are different processes used, however. In all of them, water is heated to produce steam, which carries the most volatile chemicals of the aromatic material with it. The steam is then chilled (in a condenser) and the resulting distillate is collected. The Essential Oil will normally float on top of the Hydrosol (the distilled water component) and may be separated off.
 

Steam Distillation

True Steam distillation uses an outside source of steam which pipes the steam into the distillation unit, sometimes at high pressure. The steam passes through the aromatic material, and exits into the condenser.
 

Hydrodistillation

The botanicals are fully submerged in water, producing a "soup", the steam of which contains the aromatic plant molecules. This is the most ancient method of distillation and the most versatile. It's the method most often used in primitive countries. The risk, of course, is that the still can run dry, or be overheated, burning the aromatics and resulting in an EO with a burnt smell. Hydrodistillation seems to work best for powders (ie, spice powders, ground wood, etc.) and very tough materials like roots, wood, or nuts.
 

Water & steam distillation

A water and steam distillation arrangement can be compared to a kitchen steamer basket, with the botanicals supported in a "basket" over boiling water, thus exposing the plant material only to the rising steam vapors. This is the best method for distilling leafy materials, but doesn't work well for woods, roots, seeds, etc.
 

Absolutes and Concretes: Solvent Extraction

Very delicate aromatics, Jasmine, Linden Blossom,etc. can not survive the process of distillation. To capture their magical aromas, a process of solvent extraction is used.

An extracting unit is loaded with perforated trays of blossoms. The blossoms are washed repeatedly with a solvent (usually hexane.) The solvent dissolves all extractable matter from the plant whch includes non-aromatic waxes, pigments and highly volatile aromatic molecules. The solution containing both solvent and dissolvable plant material is filtered and the filterate subjected to low pressure distillation to recover the solvent for further use. The remaining waxy mass is what is called the concrete and it contains in the case of J. grandiflorum as much as 55% of the volatile oil.

The concentrated concretes are processed further to remove the waxy materials which dilute the pure essential oil. To prepare the absolute from the concrete, the waxy concrete is warmed and stirred with alcohol (usually ethanol.). During the heating and stirring process the concrete breaks up into minute globules. Since the aromatic molecules are more soluble in alcohol than is the wax an efficient separation of the two takes place. But along with the aromatic molecules a certain amount of wax also becomes dissolved and this can only be removed by agitating and freezing the solution at very low temperatures (around -30 degrees F) In this way most of the wax precipates out. As a final precaution the purified solution is cold filtered leaving only the wax-free material (the absolute.)

This solvent extraction actually yields three usable products; first the concrete (as in rose concrete, my favorite solid perfume), the precious absolutes, and the floral waxes, for addition to candles, thickening creams and lotions as a softly floral scented alternative to beeswax.

 

Carbon Dioxide Extraction

When CO2 (carbon dioxide) is subjected to high pressure, the gas turns into liquid. This liquid CO2 can be used as a very inert, safe, "liquid solvent." which will extract the aromatic molecules in a process similar to that used to extract absolutes (above.) The advantage, of course, is that no solvent residue remains, since at normal pressure and temperature, the CO2 simply reverts to a gas and evaporates.

CO2 extraction has given us essences of some aromatics that don't yield essential oils, Rose Hip Seed, and Calendula, for examples. In my experience (or opinion!) if the same essential oil is available both as a steam distilled EO and a CO2 extracted essence, the CO2 seems to have a richer, more intense scent, since more of the aromatic chemicals are released through this process. For more details of this process and the different types of CO2 extracts please read our page devoted exclusively to the CO2 extracts.

 

Cold Pressing

We are all familiar with the spray of orange essential oil that can be released by scoring or zesting the skin of the fruit. The cold pressed citrus oils are commercial produced just this way, by machines which score the rind and capture the resulting oil. Although many citrus oils are also produced by steam distillation, they seem to lack the vibrancy of the cold pressed oils.
 

Florasols/Phytols

This extraction method uses a new type of benign gaseous solvents. In the late 1980s Dr. Peter Wilde first recognized the unique properties of these solvents for the extraction of aromatic oils and biologically active components from plant materials, for use in the food, pharmaceutical, aromatherapy and perfume industries. "Florasol" (R134a), is the solvent upon which the process is based

Extraction occurs at or below ambient temperatures, hence there is no thermal degradation of the products. The extraction process utilizes the selectivity of the solvent and produces a free flowing clear oil free of waxes.

Methods of Application

Pure essential oils have a wide range of therapeutic benefits. The method applied can effect the results you receive. First of all, please remember that almost no essential oil should be applied neat (undiluted) to the skin. "Normal dilution" is 2.5%, ie, 15 drops of the essential oil or synergistic blend to one ounce of carrier oil. Less is more when we speak of these powerful healing essences.

The most popular or common way that the oils are usually administered, in the USA at least, is through an Aromatherapy Massage. Blend your chosen blend or single oil into your choice of carrier. You don't need to be a trained massage therapist Warm hands and a gentle touch may not produce the deep muscle results that a trained Licensed Massage Therapist can produce, but long sweeping strokes can relax tensions and relieve anxiety. There are many introductory massage books on the market today, some may be ordered from our online bookstore Massage, however, is only method to receive the healing gifts of Aromatherapy. Please bear in mind that from a scientific standpoint the path the oils take to effect our bodies is through the olfactory system. It is by inhaling the aromatic chemicals that comprise these natural oils that they effect our central nervous system, and cross the "blood-brain" barrier. The issue of whether the oils are absorbed through the skin is often hotly contested. Traditionally, aromatherapists have believed and taught that the oils did enter the skin during massage, but modern testing indicates that this may well be wrong. So many other methods of delivery that allow you to inhale the volatile aromatics may be at least as effective.

The choice of delivery method often depends on the intended goal.

For Skin Care:

Facial Steam:

for skin care, part of a deep cleansing routine: 5 or 6 drops in a pint of warm water or in facial steamer.

Facial Masque:

add 3 to 5 drops to moistened clay, honey, mashed avocado, egg white, etc.

Facial Oil Blend:

use up to 15 drops of Essential Oil to your chosen carrier oil, or unscented cream or lotion.

Dry Brushing:

To stimulate the skin, and the lymphatic system all over the body use a natural bristle  bath brush with two or three drops of a stimulating essential oil (rosemary or pink grapefruit are good choices if not contraindicated) to the bristles and brush your skin, from the toes up to the heart, from the fingers to the heart, always working from the extremities toward the heart.  Brush lightly but cover your whole body.  This is effective either before or after your morning shower.  I would omit the face and neck from this process.

For sinus or bronchial problems:

I prefer to use:

Inhalation:

add 5 to 7 drops to a bowl of steaming hot water, put a 'towel tent' over the head to capture the steam. Close your eyes and inhale until water cools or until you stop smelling the oil. Repeat, if necessary, every four or five hours.

Microdiffusion:

Use a nebulizing diffuser that will break the oil into millions of micro-particles. In case of illness, inhale near the "mouth" of the nebulizer. Only four or five minutes worth should be sufficient, repeat every few hours.

Humidifier:

(cool mist). Add from 3 to 9 drops of your chosen EO to the water of the humidifier. Run overnight, or add the essential oils two or three times a day, if running continuously. Please note, the essential oils can conceivably damage a humidifier. I've never had this happen, but it is a slight risk. This is an effective method if using the essential oils with a sick child, since there is not risk of danger from hot water, etc.

General use, for colds, flu, sore muscles, relaxation:

Bath:

from 5 to 12 drops in a tub of warm water. Fill tub, add oils, swish to disperse in the water. you might try adding the oils to a spoonful of honey, a small cup of milk or cream, or to your favorite carrier oil, and then adding to the water.

Compress:

Excellent for topical application to ease pain, from strained muscles, menstrual cramps, etc. Add 4 to 7 drops of Essential Oil to a bowl of warm water. Swish the surface of the water with a cloth, wring out, apply to area, repeat when cloth cools. You may cover the warm cloth with a sheet of plastic and a towel to keep the warmth in longer. This is an excellent method for treating painful menstrual cramps.

Spritzer:

The amount of Essential Oil used depends on the purpose of the spritzer. To 4 ounces of distilled water add:
  • 8 to 10 drops for the face
  • 30 to 40 drops for an all over body spritzer
  • 80 to 100 drops for a room spray/air freshener
Shake well, spray. May be used as facial toner, to moisten a body wrap or as an all over freshener, or as a room spray. This mixture will require a lot of shaking, since the essential oils do not dissolve in water. You may first dissolve the essential oils in an ounce of perfumers alcohol or high proof vodka, or in a solublizer like the polysorbate available on our carrier oils page, then top the mixture off with approximately three ounces of distilled water.

Jacuzzi:

add three drops of essential oil per person. This may be repeated every 30 minutes. Be aware that some sources warn that the oils may do damage to plastic plumbing.

Shower:

After a shower, apply 5 to 7 drops to a damp wash clothe. Rub briskly all over the body. Preferably allow to air dry.

Bath Salts:

Use a blend of Epsom Salts (good for sore, aching muscles), Sea Salt, Baking Soda. Add 6 to 10 drops of your chose oil blend. Either add to warm bath, or use as a 'salt glow' rub before the bath. Adding a spoonful of your favorite carrier oil to the salt glow leaves your skin feeling soft and silky, but makes the tub harder to clean.

Household Use:

Laundry:

Essential Oils may be added to the washing machine, or a few drops put on a cotton cloth and added to the dryer. If using in the washer, the warnings above about possible damage to plastic or hard rubber parts would apply.
  • Adding a teaspoon of Lemon Oil to the washer will remove greasy/oily smells. (A great trick for Massage .therapists!)
  • Research indicates that adding Eucalyptus Globulous to the washing machine MAY kill dust mites in bedding.
  • Lavender EO in the dryer can scent bed linens
  • To really preserve the scent of EO's used in the dryer, add them and run on a 'no heat' cycle for a few minutes at the end of the drying cycle.

General Cleaning:

Use Lemon or Grapefruit EO, possibly with a touch of Tea Tree oil added, in the water you clean with. Wipe down kitchen counters and your bathroom with these cleansing, germicidal oils. I find that Lemon Oil in water does a wonderful job cleaning the bathroom mirror, as well as all the fixtures.

Washing Dishes:

Lemon Oil is a great grease cutter; I add a few drops to the dish pan.
And while we are in the kitchen:

Flavoring:

Either add a drop or two of a citrus, spice, or floral EO to a cup of honey, mix well and let stand, OR put a couple of drops of the same EO on a scrap of paper towel, lay on top of a jar of sugar, seal tightly and let stand for a week. Add the flavour of the fresh plant to sugar for tea, baking, etc.

Anti-bacterial Essential Oils

Please follow appropriate safety warnings. Many of the most effective oils are truly not safe for use on the skin and would do better in a nebulizing diffuser. Also, please remember that all essential oils have some antibacterial/antimicrobial effect, so oils may be chosen for other reasons and still be effective.

essential oil leaf link to tea tree essential oilTea Tree (melaleuca alternifolia)
Most frequently recommended for the treatment of athletes foot, candida, in fact any sort of fungus. Tea tree oil is an effective all round anti-bacterial, anti-viral and anti-fungal oil. Many authorities recommend using Tea Tree neat (undiluted) but much recent evidence shows that it is actually more effective in a 2% dilution. I personally consider it much too harsh to use undiluted on the skin.

Tea Tree is the usually suggested aromatherapy remedy for Ringworm. If I were trying to treat this fungal infection I'd go with a weak (ie 12 drops/ounce of carrier) dilution of tea tree in Jojoba Oil.

essential oil leaf link to Myrrh essential oilMyrrh Essential Oil Commiphora myrrha
Specifically often recommended in a blend to treat "Jock Strap Itch." I have found it effective blended with tea tree and worked into Bentonite Clay, used as a body powder. Please don't use Corn Starch in this "do it yourself" dusting powder as it tends to feed the fungus and makes things worse, not better.

 
leaf image for cedarwood essential oilsCedarwood, either Atlas or Virginia
Wonderful for clearing out musty closets or basements. Perhaps blended with Lemongrass For a basement or large area, I would suggest running in a nebulizing diffuser to really fill the atmosphere; For a closet, first wipe the closet down with a blend of the oils in water, allow to dry thoroughly (perhaps running a dehumidifier, if available)

 
leaf image for cedarwood essential oilsTagetes Tagetes glandulifera
Recommended for use with fungi that affect the feet. Tagetes is a strong photosensitizer so really shouldn't be used on other parts of the body. I've found a blend of Tea tree oil and Tagetes added to a vinegar and water foot bath very effective for athletes foot and for dealing with toenail fungus.

Lemon Eucalyptus, in a nebulizing diffuser is what I used when part of the house was flooded, wet carpets etc., last year. It is a wonderful air cleaner and strong antifungal for use in a large area.
 

Anti-viral Essential Oils

It has not been proven, scientifically, that any essential oil has specific antiviral effects. However, anecdotal evidence indicates that the following essential oils may have some antiviral effects.

CONTRAINDICATIONS
Some of the most beneficial oils can prove harmful under certain conditions. Concentrated oils are very strong, and just because a product is natural doesn't mean that it's harmless. Inappropriate use can often lead to adverse and damaging side effects. This is a partial list of medical conditions that warrant avoiding some oils. 

If you are pregnant avoid: Basil, Cedarwood,Clary, Coriander, Hyssop, Jasmine, Juniper,Marjoram. Oregano, Myrrh,Peppermint (which should also be avoided while nursing), Rockrose, Rosemary,Sage and Thyme.

Please note, the above oils are listed as contraindicated during pregnancy by most Aromatherapy authors. However, Martin Watt, the source that I respect the most regarding the safety of aromatic materials used in aromatherapy has this to say: "There are NO essential oils that used externally are proven as harmful to a developing foetus. The vast majority of oils you have listed are common food additives. This is all stuff from the aromatherapy novel writers."

If you suffer from a seizure disorder it's best to avoid Basil, Fennel, Hyssop, Rosemary and Sage.

To which Martin Watt states: "There is not a shred of evidence that the oils you mention have any adverse effect in epileptics and again most are common food additives."

If you have Hypoglycemia (low blood sugar) avoid Geranium.

To which Martin wrote "Total and utter B-S."

If you have High Blood Pressure avoid Pine, Rosemary, Sage and Thyme.

And Martin replies "There is no evidence that the stated essential oils of themselves can increase blood pressure. Of course if someone does not like their smell that might marginally increase it, but probably not.."

Those with kidney problems should approach Juniper, Sandalwood and Coriander with caution.

"No evidence and unlikely if the oils are only used externally," says Martin

The following oils can cause severe sun damage (photosensitivity.): Bergamot, expressed Lime and Rue, very strong, Cumin, Mandarine, Lemon, Tangerine, Orange, Verbena (moderate), Angelica, Caraway, Cassia,  Cinnamon Bark, Grapefruit, Honeysuckle absolute, Laurel Leaf Abs., Patchouli (mild), Virginia Cedarwood, Dill weed, and Petitgrain (very mild.)

Consider any cold pressed citrus oil a potential photosensitizer.  Steam distilled citrus oils, on the other hand, do not carry this risk. St. John's Wort CO2 and infused oil are also photosensitizers.

Clary should not be used when consuming alcohol, because it can greatly increase its effects. Marjoram and Chamomile can cause drowsiness.

If you are anti-coagulant therapy (blood thinners) avoid oils high in Eugenol (clove, cinnamon leaf and bay laural (pimenta racemosa).

Two oils with almost identical components that are too dangerous to use lightly, if at all, are Birch (Betula lenta) and Wintergreen.  They have their own page.
 
Sensitizing oils:  Essential Oils with a proven or suspected history of causing sensitization (allergies):  Aniseed, Bay, Benzoin (indeed, any Styrax oil), Balsam of Peru (VERY HAZARDOUS), Calamus, Cardamon (suspect), Cassia, Cinnamon Bark & Leaf, Citronella, Clary Sage (suspect), Costus, Dill Seed (not Weed), Fennel, Bitter,  Fig Leaf Absolute, Galbanum Resin (cross sensitizing with Peru Balsam),Hyacinth abs. (suspect), Jasmine Abs. Junipers (suspect)  Laurel (bay laurel), Lemon (suspect), Litsea Cubeba (suspect) Lovage (suspect), Mimosa Abs., Oakmoss Concrete (suspect), Orange (suspect),  Pines (suspect) Rose Abs. (if used in high concentrations.) Spearmint, Tolu (balsam, VERY STRONG?)  Tagetes, Tolu Balsam, Turpentine,Lemon Verbena (The IFRA strongly advises against the use of Verbena oil in cosmetics or perfume products.)Ylangylang (in very high concentrations.)

Some toiletries makers recommend the use of Benzoin oil or resin as a preservative. This practice is of enough concern that a special page has been devoted to the possible results of its use.

NOTE, some oils should not be used by anyone except a clinically trained aromatherapist. Among them are Birch, Sage, Thuja, and  Wintergreen,
 
Carcinogenic oils:  Calamus (European and Asian), Sassafras.   (Please note: Sassafras E O is banned for use in cosmetics and toiletries in all of Europe.)

Others have such  potentially dangerous effects as to make them too risky to experiment with. The oils on my personal 'to be avoided at all costs' list are: Bitter Almond, Calamus (grown in Europe or Asia, the Canadian/USA grown is safer) Yellow Camphor, Horseradish, Mugwort, Mustard, Rue, Sassafras, Southernwood, Tansy (other than Annual Tansy),  and Wormwood.
