About Essential Therapeutics…

I became enamoured of the possibilities of Aromatherapy while I lived in San Francisco in the early 1980’s. Emigrating to Australia in 1986, I had the good fortune to study and work with Dr. Daniel Pénoël while he lived in Melbourne. Dr.Pénoël is a medical physician renowned for his passion and expertise in the practice of Aromatic Medicine - or the more clinical uses of aromatic extracts and essential oils in the vein of phytomedicine (or herbal medicine).

At that time, Aromatherapy was just becoming popular. However, what was locally available as “essential oils” left much to be desired. Based on how French physicians, naturopaths and pharmacists utilised essential oils effectively for treating a wide range of conditions, it became very clear that only real, authentic, guaranteed essential oils were suitable for therapeutic use and this was further confirmed in my own clinical work with clients.

Essential Therapeutics began in 1988 as the first and still the only professional range of essential oils and related products, specifically for use by trained complementary therapists and health care professionals. In 1994, we were amongst the first group of Aromatherapy companies to apply for registration with the Australian Therapeutic Goods Administration (TGA).

This registration as a licensed therapeutic goods manufacturer allows us to make substantiated therapeutic claims where possible and demands that we follow Good Manufacturing Practice standards (GMP), an international standard controlled by the Pharmaceutical Inspection Convention Scheme. These GMP standards include an annual independent audit by the TGA to ascertain our on-going compliance with all the standards, including quality assurance. Such a program of independent verification by a governmental authority for Aromatherapy products is completely unique to Australia and further assures you of our commitment to real quality.

In 1997 Essential Therapeutics joined with Australian Botanical Products in to offer a comprehensive range of guaranteed products, supported by a large number of expert, dedicated staff. Our overall wealth of international relationships with growers and suppliers and our in-house technical expertise cannot be surpassed.

If you are truly interested in the possibilities of Aromatherapy and Aromatic Medicine, I heartily invite you to experience the essential difference that real, guaranteed quality provides.

Aromatically Yours,

Ron Guba

TGEO Guaranteed Essential Oils & Aromatic Extracts

The Therapeutic Grade Essential Oil Quality Guarantee

Aromatherapy, or the therapeutic use of plant essential oils, is a potent natural therapy that serves to heal and harmonise many imbalances of body and mind.

The effectiveness of aromatherapy is directly dependent on the quality of essential oils employed.

We at Essential Therapeutics are pleased to offer you our extensive range of TGEO Guaranteed Essential Oils.  Through extensive travel, research and analysis over the past seventeen years, we have compiled this range of simply the world’s finest therapeutic quality essential oils and aromatherapy products.

Instead of depending on the usual Fragrance and Flavour companies here and overseas (with the real problems of dubious product quality), we deal directly with growers, producers and trusted distillers whose sole interest is in producing and supplying only the highest quality essential oils.

Why does quality matter?

If one looks at herbal medicine products out in the marketplace in Australia, we see almost exclusively products that are listed with the Australian Therapeutic Goods Administration and are guaranteed in their quality. That is, the products actually contain what they claim to contain!

If one is to expect real therapeutic outcomes from herbal medicine – or any therapeutic product, we must be assured that we are using a real product – one that is backed up by expert testing and audited independently. Hence, this is exactly what we should expect when we wish to enjoy the therapeutic benefits of pure essential oils.

However, the whole plethora of Aromatherapy products available throughout the world does present a different picture. Many of the products available to the public are life style products that use the concept of Aromatherapy. There is no particular therapeutic claim being made, even though it often is implied. The ingredients contained may simply “commercial” or adulterated essential oils or synthetic fragrance compounds. This is simply the reality of consumer products that exploit the popular ‘feel good’ idea of Aromatherapy.

More to the point, however, are the availability of so-called essential oils from companies that are happy to promote their products as 100% pure and natural Aromatherapy oils to unsuspecting complementary therapists and health care professionals, along with the general public. Even though these essential oils are guaranteed to be pure, we have seen that many of these oils are in fact adulterated.

The loophole here is that no therapeutic claims are made for the products. Hence, the essential oils can be promoted as 100% pure and natural, without ever having to pass ANY quality control standards, such as is demanded by the Good Manufacturing Practice standards of the Australian Therapeutic Goods Act. The actual quality of such products has been demonstrated to be from satisfactory to highly adulterated. You might even be provided with a Certificate of Analysis - that quite truly is not worth the paper it is printed on. Let the buyer beware!

When it comes to the true therapeutic uses of essential oils, quality DOES matter.

Our Quality Assurance Program

To fully guarantee the authenticity of each and every essential oil that we provide, we undertake an extensive range of Quality Assurance procedures.

In 1991, John Fergeus, our Managing Director, acquired our first Gas Chromatography/Mass Spectrometry (GC/MS) unit (our latest in 2005). GC/MS analysis, combined with other standard physical tests, is simply the state-of-the-art method for analysing essential oils for authenticity.

However, having this equipment is not enough by itself. John Fergeus and our other QA staff (including two with Ph.D.s in organic chemistry) have spent countless hours of study, publishing articles in scientific journals, attending scientific conferences, etc., etc., to specifically become expert in the analysis of essential oils.

In other words, simply to send a sample of an essential oil out for analysis to a company or University who will do simple gas chromatography or GC/MS analysis may not be fruitful. Or, simply for marketing purposes, a company will purchase expensive analytical equipment. However, unless an operator is a real expert in essential oil analysis and up-to-date with all the possible aspects of adulteration, you will likely only receive some identification of major components at best.

Hence, a Lavender oil sample may be shown to meet the British Pharmacopoeia (B.P.) standard, with appropriate levels of linalool, linalyl acetate and camphor as prime components, as well as basic physical tests. The oil can then be passed off as real Lavender oil, even perhaps being supplied with a Certificate of Analysis.

However, upon closer inspection (which we have done many times on Lavender samples), one may very well find on GC/MS analysis, trace amounts of compounds such as dihydro linalool. Detection of such a compound is a sure sign that the oil is a blend including synthetically produced linalool. The dihydro linalool is a by-product of synthetic manufacture, never found in True Lavender oil.

We have developed an extensive adulteration library, giving us the capability to detect even the most sophisticated adulteration for each and every essential oil that we provide.

Therefore, without expert analysis, so-called essential oils can be demonstrated to meet various standards (B.P., ISO, AFNOR) relating to chemical composition, yet be quite adulterated.

As well, the demand for guaranteeing species purity is routinely disregarded by flavour & fragrance suppliers. That is, True Lavender should be exclusively from Lavandula angustifolia, not hybrid Lavandin, L. intermedia. Hence, it becomes an issue of what level of adulteration remains undetected.

Therefore, an essential oil can meet all the Australian TGA/GMP standards and be “passed” to be promoted as a “therapeutic” product, yet be an inferior, adulterated essential oil. It is our in-depth analysis and our long-term relationships with distillers that allow us to fully guarantee our oils as 100% genuine & authentic.

Most importantly for our customers, we do not depend on out sourcing our product analysis to other companies. We have a dedicated, expert Quality Assurance team that fully analyses and guarantees every essential oil that we offer.

Examples of adulterated essential oils

Following are just two examples of adulterated essential oils that are offered as “100% pure & natural” Aromatherapy oils. These oils were analysed in-house, using our own Gas Chromatography/Mass Spectrometry (GC/MS) equipment. Over many years of essential oil analysis, we are expert at detecting adulteration and understand the procedures used by flavour and fragrance companies in creating blended products.

We have chosen Lavender essential oil as a useful example.

Sample One

This is an example of a grossly adulterated essential oil. It appears this product has passed through at least two levels of construction, first as a Lavandin blend with synthetics and inexpensive fractions of essential oils added, then further blended by another company to create an inexpensive “True Lavender” blend. This product is being promoted in bulk as a fine “Aromatherapy grade” True Lavender essential oil and is a good example of conscious fraud by an unscrupulous company. Such a blended product has its uses in say, fragrancing a laundry detergent. But it does not belong in small bottles as an authentic True Lavender oil for therapeutic use. Unfortunately, more than one Aromatherapy company uses this and similar blends.

Peak 1  Alpha-pinene 6%. This is only found in tiny amounts in True Lavender. Inexpensive terpene fractions have been added.

Peak 2  1,8 cineole 8%. Cineole is less than 1% in True Lavender oil. The high cineole content is a sign of the cheap Lavandin oil used in the product.

Peak 3  Linalool 25%. This is an appropriate amount of linalool for True Lavender. However, we detected plinol as well in small amounts, which demonstrates that synthetic linalool has been added, synthesised from turpentine.

Peak 4  Camphor 5%. As with 1,8 cineole, this high camphor content is from the Lavandin/synthetic blend used.

Peak 5  Linalyl acetate 30%. This is a reasonable amount  of linalyl acetate which is found in both True Lavender and Lavandin. The source here is from Lavandin oil with added synthetic linalyl acetate. Because the Lavandin oil in the blend has been diluted with other added compounds, synthetic linalool and linalyl acetate were added to boost their content to levels seen in natural Lavender oil.

Peak 6  Isobornyl acetate 7%. This compound, with a pine needle odour, is synthesised from turpentine from Pinus species. It has been added to improve the overall aroma.

Peak 7  Mineral oil 10%.  You will see the peaks under # 7. These represent various sesquiterpene compounds naturally occurring in both True Lavender and Lavandin oil. However, notice the “hump” above the arrow. These are a variety of hydrocarbon compounds found in petrochemical-derived mineral oil. It has been added to reduce the price further and the producer hoped the mineral oil would not be noticed “hiding” under the sesquiterpenes.

Sample Two

This is an example of a more sophisticated level of adulteration. This oil is sold in small bottles to therapists and the public by an Aromatherapy company. This product meets the B.P. standard (British Pharmacopeia 2003) for True Lavender oil in terms of the proper content of major constituents. The BP standard is used as a standard for essential oils by the Australian Therapeutic Goods Administration.

However, the B.P. standard states: “Essential oil obtained by steam distillation from the fresh flowering tops of Lavandula angustifolia Miller (Lavandula officinalis Chaix)”. In other words, the true essential oil obtained from the correct species. This blended product is not from Lavandula angustifolia, but a blend of inexpensive Lavandin (Lavandula x intermedia) and synthetically produced compounds naturally found in True Lavender essential oil.

This is a magnification of the GC/MS analysis, with the corresponding mass spectra for dihydolinalool and dihydrolinalyl acetate. These compounds are only present in trace amounts and are missed by standard gas chromatography analysis. These two compounds do not occur in any essential oil. Dihydrolinalool and dihydrolinalyl acetate are only produced as by-products when synthetic linalool and linalyl acetate is made from acetylene gas as a starting point. In the BP 2003 standard, linalool must be present from 25.0% to 46.0% and linalyl acetate, 25.0% to 46.0% in True Lavender essential oil. Synthetic linalool and linalyl acetate were added to this product both to meet the BP standard and to enhance to aroma. Linalool and linalyl acetate are also major constituents in other essential oils, such as Bergamot and Clary Sage. Adulteration with synthetic linalool and linalyl acetate is also common in these essential oils.

An example of true, True Lavender oil

Following is a typical GC/MS analysis of the Essential Therapeutics certified organic True Lavender essential oil. This essential oil has the proper, balanced profile of True Lavender with no adulterants. It is vetted by Australian Certified Organic to be from certified organic growing practice. It is a population Lavender oil, meaning that the plants are grown from wild harvested seed, not from genetically identical cuttings, as in clonal Lavenders. Hence, population Lavender closely corresponds with wild-harvested Lavender.

Quality Assurance Procedures:

Following is a diagram of the procedures and analysis that every essential oil that we provide must go through.

It must be said that we have long-standing relationships with our major distillers and growers. They do not provide us with adulterated essential oils! Certainly, our quality assurance program will always “keep them honest”, should it ever become an issue.

More to the point are potential distillers, who provide us with samples of essential oils they wish to offer us. In this situation, our QA testing has demonstrated adulteration on various occasions. Such results settle the matter very quickly, with an immediate ban placed on the distiller.

The Therapeutic Grade Essential Oil (TGEO) Guarantee

Decidedly, our extensive Quality Assurance program is unique amongst Aromatherapy suppliers. Our procedures fully meet and surpass all the requirements of the Australian Therapeutic Goods Administration (TGA) and the necessary Good Manufacturing Practice standards.

Above and beyond the TGA standard, we offer you complete assurance on each essential oil that we provide:

1. Purity

All essential oils are guaranteed to be 100% pure and 100% natural. There is no addition or blending of cheaper essential oils (such as reconstituted Melissa, or cheap Lavandin blends) and no addition of synthetically derived aroma chemicals (such as in enhancement with synthetic linalool). All essential oils are fully analysed for purity, using state-of-the-art GC/MS technology.

2. Name and Extraction Method

The accepted common name is given and the plant part used is specified (further details are in our product guide).

3. Defined Botanical Species

Therapeutic Goods requirements do demand that the exact botanical species is to be used. However, we have seen that this requirement can be bypassed, as a simple analysis to meet a “standard” leaves room for the blending of oils from less expensive species, as in the case of Lavandin and True Lavender. We make certain that we provide you the exact botanical species as stated and the chemotype where applicable.

4. Country of Origin

The proper country of origin is stated. We source essential oils from around the world and we provide a wide range of high-quality Australian oils.

5. Growing Method

An important and unique aspect of our TGEO Quality Guarantee is to provide the growing method for each essential oil:  Select, Traditional, Wild Harvested, Organic or Wild Harvested / Organic.

Further Quality Assurance

All our essential oils are packaged under the Australian TGA Good Manufacturing Practice Standards, which includes:

  • The batch number is on every bottle, so we know exactly where the oil came from and to account for any natural variations from harvest to harvest. We store all our essential oils in a temperature controlled environment, and oils prone to oxidation, such as our citrus oils, we refrigerate and store under nitrogen gas.
  • The listing number (the AUST L or AUST R number) means that we have listed the essential oil as an approvedtherapeutic product that we can offer TGA approved therapeutic claims for.
  • Our storage methods and the inclusion of an expiry date on every bottle guarantee you freshness.

In summary, our TGEO Guarantee assures you of our commitment to provide you the highest quality essential oils available for the true practice of Aromatherapy.

We certainly hope you enjoy them.
