Their are two major problems with these notes.

1. The complete confusion of teachers and authors between the therapeutic activities inherent in the herbal extract and the essential oil.

2. The highly misleading, inaccurate and sometimes dangerous, generalizations of therapeutic activity based on single chemicals occurring in essential oils.

Here are a few examples:

Cypress OIL treats:
“low blood pressure, poor circulation, varicose veins and hemorrhoids, urinary problems and cellulite.
It is reduces excessive fluids in the body associated with conditions such as diarrhea”.

ALL of these actions could only be achieved via the use of the herbal extract.
Since most essential oils are classified as ‘rubefacients, i.e. increase capillary circulation, then the external application to varicose veins is more likely to cause irritation, rather than cool the skin and astringe it.
On the other hand, the application of a herbal lotion containing tannins and other compounds not occurring in an essential oil, may well have a cooling and astringent effect on the skin.
Cypress oil for hemorrhoids may have a mild antiseptic and healing effect, but again the traditional use was the application of a water based solution, NOT the essential oil.

“Cypress to reduce excessive sweating”.
How can it do that if a rubefacient effect of the oil does the reverse.  Again a complete corruption of the use of the herbal extract.

Eucalyptus radiata and Ravensara:
“Good for HIV and AIDS”.  There is no sound evidence that these oils more than any others are good for these conditions.  Both oils have not undergone any Internationally acceptable testing for potential adverse effects.
It is therefore unwise to use such substances on human skin and extremely unethical to use them internally.

Fennel:
“Reduces obesity, water retention, urinary-tract problems, indigestion and babies' colic.
Its estrogen-like hormonal properties increase mother's milk”.

To even suggest that the external application of fennel OIL can reduce obesity is ludicrous.
The OIL has not been traditionally used for that problem.  Any references in traditional medicine are to the internal consumption of either the seed or a tea made from the herb.
Fluid retention and effects on the urinary tract can be achieved via the internal use of the seed or oil.  However if these effects can be achieved via the external use of the oil is doubtful.
The estrogenic effects of trans-anethol are still open to debate within the scientific  community.
It looks increasingly likely that it does not have this effect.
Again we must look at the traditional uses of this plant to find where all this nonsense has come from.
The whole SEED is what was used to increase mothers milk.  Seeds of course contain many nutrients in a highly concentrated form, ideal for helping mom produce good quality milk.  The seed may also contain other water soluble substances which may affect the hormone system.
Such chemicals may not occur in the essential oil at all.

Melaleuca viridiflora (quinquenervia) NIAOULI:
Useful for
“coronaritis, endocarditis, viral hepatits, gastro and duodenal ulcers, bilary lithiasis, cholera, tuberculosis, cancer of the rectum”????

It is beyond belief that a leading aromatherapy figure should teach such utter nonsense to unsuspecting students.  So for those who can’t work it out for themselves I will go through this list.
Coronaritis and endocarditis are severe inflammatory conditions and potentially life threatening.
There is no evidence that I am aware of that this oil applied externally can affect these conditions.
More importantly, if someone was suffering such a condition the chances are they would be in hospital and no aromatherapist would be allowed to treat it.

Viral hepatitis; a very nasty illness and also potentially life threatening.  What on Earth is this oil supposed to do?  I have never seen any research papers proving niaouli oil to be an effective virocide in-vivo.  Most such information comes from extremely obscure and unreferenced publications emanating from France.
 
Duodenal ulcers; what on Earth is the external application of oil of niaouli going to do for that?   Since it is now known that most gastric ulcers are caused by helicobacter pylori, the oil would need to be given internally to have any effect.  I have never seen any data showing tests on this organism using essential oils.

Bilary lithiasis;  the mear suggestion that the external application of an essential oil is going to dissolve stones defies belief.  Massage over such an organ is strongly contra- indicated, because the potential exists to move the stone and impact it into the wall of the gall bladder.

Cholera; I am not aware of niaouli oil having been proven effective in-vivo.  We must always be most cautious in assuming that tests conducted in petrie dishes will have similar effects in humans.

Tuberculosis;  I am not aware of niaouli oil having been proven effective in-vivo.

Cancer of the rectum;
this sort of dangerous nonsense is just what gets aromatherapy looked on as ‘quack medicine’ by the mainstream medical profession.  I just could not believe my eyes when I saw this one, I have seen some rubbish in aromatherapy course notes, but this really tops them all.
What makes it even worse, is that these particular claims are from the course notes of a leading figure in the Aromatherapy Organizations Council.

Rosewood:
The native South American tribes have no known use for this essential oil.  This means that ALL the therapeutic data hails from European practitioners.
They largely based their therapeutic properties on the fact that the oil contains a lot of linalool.   In fact this chemical occurs in two isomeric forms, one isomer occurs in lavender and ho leaf and the opposite isomer in rosewood.  As the differences between the actions of different isomers can be profound, one simply can not assume therefore that the actions of rosewood will be similar to those of lavender.
Various species of rosewood are on endangered species lists.  Products from these protected species are banned under International trade agreements.  Therefore the importation of genuine rosewood oil might be illegal.
Most rosewood oil is either synthetic linalool, or oil derived from the LEAVES of these trees. In which case it is a misleading trade description because a WOOD oil, can not be the same as a LEAF oil.

Yarrow:
No varieties of yarrow oil have been adequately tested to ascertain if they are safe or not.  Since fresh yarrow herb is a well documented skin sensitizer, the potential for skin sensitization for the essential oil can not be ruled out.  Most of the claimed therapeutic effects are those attributable to the use of the herbal extract
NOT THE OIL.
Anti inflammatory effects are those attributed to the azulene’s in some oils.  However certain chemotypes of yarrow contain no azulene’s (the clear oils).  Even if the blue oil is used, the fact that one component may be anti inflammatory is useless if the oil also contains low levels of sensitizing agents.  These sensitizing chemicals can be so powerful, that they may overcome the anti- inflammatory effects of the azulene’s.

CHEMICAL COMPOSITION:
Giving therapeutic properties to an oil, based on the individual molecules that it contains, is most inaccurate.  It displays a fundamental misunderstanding of the chemistry of essential oils.  Making guesses as to the likely effects of an essential oil by examining its major constituent chemicals is fundamentally flawed. That is particularly misleading where the external application of an oil is concerned.
The SMELL of an oil certainly contributes to its clinical effects.  The major chemicals occurring in an essential oil commonly play little part in the fragrance of the oil.  Key fragrance molecules frequently occur at only a few parts per million.   Therefore you can have 99%+ of the chemicals in an essential oil that do not contribute to its smell.   Even if an oil is taken internally, the major chemicals may not be the most important ones.
Most oils contain hundreds of different molecules and many of these are still unidentified.  Therefore one can not dismiss the possibility of extremely important molecules of great therapeutic relevance also occurring in minute volumes in the oil.

“Ketones are known to be abortifacient”.
There are no essential oils which can be legally purchased  in Europe that are  “known to be abortifacient”.

“Aldehydes are anti-inflammatory”.
Such generalized properties given to chemical groups are extremely misleading and potentially hazardous.
For instance cinnamic aldehyde in cinnamon bark oil is extremely irritating, so how can that be “anti- inflammatory”?
I could go on for pages on these grossly over simplified statements on the therapeutic properties of essential oils, based on their chemical make-up , but will leave it at this.

Some therapeutic claims:

Anemia:
Yes some aromatherapy teachers still say essential oils can treat this condition.
Many plant medicines and foods contain high levels of iron as well as other chemicals which may influence the production of, or oxygen carrying capacity of, red blood cells.  However these substances tend to be water soluble and do not occur in essential oils.  The suggestion that such a serious condition as anemia can be influenced by the external or internal use of essential oils is appalling.
It could lead to life threatening illness caused by ineffective treatments.  Such a suggestion is beyond belief and defies all medical science as well as most traditional medicine knowledge.

Blood pressure high/low:
Since most aromatherapy course providers and authors have never been taught how to take blood pressure, how do they know what effects these oils may have?  A group of nurses I trained in aromatherapy some years ago, took the blood pressures of their clients before and after an aromatherapy massage.
The tendency was a slight (3-4 mb)  transient drop in pressure no matter which essential oils were used.
This effect was probably as the result of the C.N.S. relaxation caused by the treatment.
No increase in pressure was detectable due to the unloading of lymphatic fluid into the circulation, resulting from the massage.

Conjunctivitis:
“Eucalyptus species, lemon, melissa, myrtle in an eye ointment”.
The suggested oils for this condition are very hazardous. Such oils would cause very severe inflammation and pain if they got into the eyes.

Diabetes:
Suggested oils-eucalyptus ssp, fennel, geranium, juniper, lemon, salvia lavandulaefolia.
Does anyone seriously believe that aromatherapy can cure or even relieve this condition?
Once again a serious medical condition that aromatherapists should not attempt to treat without  a registered doctors back-up.

Hepatitis:
Many plants used as herbal extracts have been used for this condition.
However there is not a scrap of evidence, traditional or otherwise, that the same plants essential oil applied externally can have the slightest effect.

Lymphatic congestion:
Since there is no sound evidence that externally applied essential oils can reach the lymphatic system, then how can they “decongest” it?
Surely it is the MASSAGE that does that, not the essential oils used.

Sperm insufficient:
“Aniseed, fennel, geranium, rose”. 
Wow medical discovery of the Century!!  Essential oils applied externally increase sperm production do they???

Vision poor:
“Aniseed, black pepper, German or roman chamomile, fennel, hyssop, lemon, myrtle, rosemary”.
Well how do you use them and how do they work?  I have used all these and still need glasses.
Sounds like another medical discovery of the Century, or quackery, you choose which!!

“Absolutes should not to be used for therapeutic purposes”.
IN FACT several floral absolutes have been extensively tested on humans for adverse effects and are passed as safe if used in the appropriate amounts.
Several absolutes are permitted food additives under EEC, FDA & WHO regulations.
Solvent residues are subject to International regulations, and these levels are only a few parts per million if for food use.  Therefore the use on the skin in aromatherapy is perfectly safe, provided the maximum levels recommended by RIFM are not exceeded.
As absolutes are cold processed, they represent the perfume found in the living plant much more closely than the equivalent distilled essential oil.

“Distillation was invented in the 13th Century, or by Avicenna”.
In FACT Al Kindi an Arab physician circa 870 AD writes extensively in his ‘Medical Formulary’ & ‘Book on the Chemistry and Distillation of Perfumes’ about essential oils and distillation.
His knowledge of the techniques would appear to be of even more ancient origin.

“Fennel, peppermint and rosemary should not be used in pregnancy”.
This statement is ridiculous, they are all permitted food flavors. Peppermint is of course widely used in confectionery and many others products. The volume of oil getting into the body from an aromatherapy treatment, is likely to be far lower than from perhaps drinking a small glass of creme-de-menthe.
One small after dinner glass is not going to cause any harm and indeed because of its calming effects on the digestive tract, it may stop a baby being buffeted by wind.
Liqueur bottles do not say “do not use if pregnant”.
Traditional Chinese and astrological attributes: Several Herb’s in some peoples books/notes are given therapeutic and energetic properties based on Chinese traditional medicine, or astrological factors.
However when one looks in detail at the Herb’s, surprising one finds that some were unknown to the Ancient Chinese practitioners. Therefore any actions such as “regulates Liver-Qia–clears heat” can not be of Chinese origin.
Herb’s such as eucalyptus were unknown to the Ancient civilizations in the Northern Hemisphere.  It was mainly their observations over thousands of years, which resulted in astrologicaly based attributes given to plants.
Any planetary signs given to plants unknown in the civilizations referred to, have been ‘made-up’ in recent times by western practitioners and therefore have no historical basis whatsoever.

Summary:
Some readers of A.T. will be aware that I have been saying for a long time that quality of education within aromatherapy is a lottery. And that membership of certain trade associations who claim to 'set standards' in reality is no evidence of educational quality at all.
I thought until I acquired the material mentioned above, that I had enough evidence.  However, now I have a new stack to justify my claims that some appallingly dangerous and highly misleading trash is being taught and by so called 'leading lights'.
People often say "well if you don't like what is being taught, why don't you work with these people to improve things".  My reply is "me work with criminally incompetent con-merchants, you must be joking".
My definition of a con-merchant: Someone who makes money by selling low quality, phoney or dangerous goods and services, or giving the impression that they have a good knowledge of their subject when in fact it is very weak. People in the health care business that do this should be jailed for fraud, or better still be given a high colonic of undiluted cinnamon bark oil.
That might get them to change their ways more than jail ever would!!
