Aromatherapy in Australia is a holistic healing treatment that has been used by humans for thousands of years and it is becoming increasingly popular in Australia. But if you are wondering exactly what aromatherapy is, this is your definitive guide! Aromatherapy is essentially the use of aromatic plant oils, including essential oils, for psychological and physical wellbeing. The different chemical constituents and aromas can produce different reactions.
Aromatherapists typically blend therapeutic essential oils individually for each of their clients and suggest methods of use such as massage, topical application, vaporised in an oil burner, via aromatherapy candles or added to a bath to stimulate the desired responses.
Aromatherapy has not yet undergone as much scientific scrutiny as other complementary therapies, but it may be effective in helping with some complaints.
In terms of aromatherapy and the brain, it is thought to have therapeutic effects by stimulating the olfactory system. This is the structure of the body responsible for our sense of smell. It begins in the nose, and there are millions of chemical receptors here that detect odours and send signals to olfactory bulbs. These signals are sent along olfactory tracts to the brain’s olfactory cortex. This is the temporal lobe of the brain where the processing of these aromas happen and is part of the limbic system.
This is the part of the brain which controls functions such as heart rate, breathing, memory, blood pressure, hormone balance, stress levels, survival instincts and the processing of our emotions. Hence, smells are processed and can influence behaviour and mood via several chemical processes.
The history of aromatherapy begins over 3500 years BC when it was used for perfume, medicine and religious purposes. The term “aromatherapy” was invented in 1935 by French chemist, Rene-Maurice Gattefosse, after a burn incident where he claimed he treated it effectively with lavender essential oil.
Plant and plant extracts have been used empirically for thousands of years, and evidence of this can be found in Iran, India, China, Pakistan, and Ancient Egypt. But it was not until 1830 in France, a city of perfume makers, that the study of essential oils came into being. Some of the leading scientists of the time, including Louis Pasteur, took an interest in it and as early as 1887, Pasteur’s assistant, Charles Chamberland began scientifically measuring the antiseptic effects of clove, oregano and cinnamon essential oils.
In 1910, chemical engineer René-Maurice Gattefossé discovered the therapeutic properties of pure lavender after an explosion in his laboratory. It left him with significant burns, and he treated them using lavender essential oil. He then founded the French Society of Aromatic Products and published works that are still considered references today. These works would give aromatherapy its very name, and he coined the term “aromatherapy” in 1935.
In 1929, pharmacist Sévelinge demonstrated the antibacterial efficacy of certain essential oils. In the 1950s, a military physician used them to treat injured soldiers in Indochina, and in 1975, aromatologist Pierre Franchomme proposed the concept of “chemotype”, listing the key aromatic compounds characterising each plant and how they affect its properties.
Today, aromatherapy is more frequently the focus of scientific studies and is recognised as a fully-fledged branch of medicine.

Aromatherapy candles are a simple but effective way of influencing the mood of a room to create a tranquil and harmonious environment. They provide natural light rather than artificial light from devices etc. which studies have shown can restrict our melatonin, make our brain more alert, and reduce our sleep. They are also wonderfully decorative and can create nostalgia if they mirror a scent of a favourite activity or event.
For maximum aromatherapy benefits, candles should be made from naturally based ingredients that don’t release toxins as they burn. Aromatherapy soy candles made from soybean wax are a popular option, as these are considered better for the environment than petroleum-based candles.
When buying a candle it is also worth reading the label to make sure it contains pure aromatherapy oil and no synthetic fragrances or dyes.
With an aromatherapy diffuser, essential oils are extracted using steam or water distillation. The oil then condenses as it cools. They can be dispersed into the air from various devices, including essential oil diffusers, mini personal diffusers, electric vaporisers and even aromatherapy car diffusers. Not only does this enhance your environment by creating a beautiful smell, but they also ensure we safely receive the benefits of essential oils through inhalation.
They also offer a simple way to try aromatherapy for sleep — just add a few drops of your preferred sleep or custom oil blend as bedtime approaches. Be mindful of diffusers if you
In terms of aromatherapy and natural skincare, if you’re planning to use oils topically, you will need to dilute them with a carrier oil first. As a general guide, it is recommended that you use a two to four percent dilution for body application and a one to two percent dilution for facial application. Carrier oils to try include olive, jojoba, sunflower, grapeseed or sweet almond oil.
Essential oils can also be used topically by adding a few drops to a warm bath, buying products that include them or adding a dilution to a glass roller bottle and applying to your pulse points — your wrists, temples, the soles of your feet or behind your ears.
If you love the use of oil with your massage, professional massage therapists will typically use a combination of a carrier oil and an essential oil or oils. Some of the benefits of aromatherapy massage treatment combined with specific essential oils include:
If you prefer not to inhale essential oils through a diffuser, you can give yourself some DIY aromatherapy by adding a few drops of essential oil to a tissue, hanky, cotton ball or face washer. Let it dry and then keep it nearby as you relax before bed. You can even tuck it into your pillowcase or leave it by your bedside.
Here are some of the best aromatherapy books on the market, including those by Australian aromatherapist, Salvatore Battaglia.
Aromatic plant oils are very potent and should never be swallowed, applied undiluted to the skin or used in any orifices. People with asthma and those prone to nosebleeds should use caution when inhaling vaporising oils. Some aromatic plant oils are toxic and should never be used at all – for example, camphor, pennyroyal and wintergreen.
Some essential oils for sleep, like cedarwood and bergamot may increase sensitivity to sunlight. Always check whether an oil is considered phototoxic before applying it to your skin. If you plan to add oils to a diffuser, make sure those oils are safe for children, partners, and pets.
Read up on an essential oil before you make your purchase. If you have sensitive skin, allergies, or underlying health conditions, you may want to talk with your doctor before trying essential oils. There may be an allergic reaction, such as a skin rash in susceptible people in some cases. Some of the oils that may cause problems include:
In terms of aromatherapy and pregnancy safety, anything you take into your body may reach your baby, and it’s possible that traces of the oils can cross the placenta. That’s why it’s best to be cautious and talk to your doctor or midwife before using essential oils.
As long as your pregnancy is going well, it may be fine for you to use:
Don’t use the following essential oils while you’re pregnant:
In some circumstances, it’s best not to use essential oils at all. Don’t use any oils if you:
Some essential oil brands will have a safety data sheet or certificate of analysis or both for their essential oils. These documents break down the components in the oil and outline any potential safety risks or hazards. They will confirm that the essential oil you purchase contains exactly what it’s supposed to and nothing more. Transparent essential oil retailers will stand behind the quality of their products by making this documentation readily available. You should also:
Here are some guidelines to follow when choosing an aromatherapist.
Once you’ve found a potential aromatherapist, it’s worth asking them the following questions to ensure they are credible and suitable for you.
If you’ve dabbled with essential oils at home but want to use them more extensively, then you may want to consider booking a consultation with an aromatherapy practitioner, who can discuss your specific needs and requirements and devise an appropriate treatment plan.
Consultation is an important aspect of aromatherapy, enabling the therapist to complete a needs assessment and develop a treatment strategy for you. They will typically gather information relating to your general health, diet, medical history, lifestyle, the reason for treatment and even your scent preferences.
While your appointment may involve a full or partial body massage, it is only one of the ways aromatherapy can be used. These include compresses, bathing and inhalation. For example, if you are experiencing stress, they may develop a treatment plan that involves both a professional massage and a bathing product to use at home. If you are suffering from sinusitis, the therapist may make up a product for you to inhale via a burner or diffuser. If you are experiencing muscle tightness or tension, they may provide a blended essential oil product to use in a therapeutic ointment or hot or cold compress.
At your follow-up consultation, the therapist will typically undertake a short assessment with you to determine whether there have been any changes to your general health, medical history, general health, lifestyle and diet. This ensures that the oils best suited for your individual needs were selected or whether they need to change.
In terms of a treatment plan, they will probably advise you to rest and relax after treatment and stay hydrated in the short term. In the long-term, they may give you a product to use or, if qualified to do so, give you some exercises to do to help, for example, to ease tension in tight muscles. They may also refer you to your General Practitioner for more specific advice if they think it is appropriate to do so.
