Modern Aroma Medicine: Essential Oils for Influenza Protection?
With more people investigating ways to support their immune system, and perhaps go so far as to actually prevent infection from influenza viruses (Swine flu, for example), a primer on essential oils and infectious illness is in order. There are several natural medicines available which have solid backing in flu prevention: zinc lozenges and elderberry extract are two very popular items. Though little attention has been given to the use of essential oils for this purpose. It is the position of many leading aroma-medicine practitioners that the use of oils for the treatment and prevention of infectious illness is the area of medicine where these products will be of greatest help to mankind. AND, there is a growing body of scientific evidence revealing true antiviral and immunostimulating effects of essential oils. Here’s a look at the research, and some easy-to-use recipes and techniques one can use to protect the immunity of themselves and their families.
Essential Oils’ Antiviral Activity: The Research
In the last few years, more laboratory research has been performed revealing the ability of essential oils to actually destroy viruses. In addition, a limited number of papers have been presented noted that oils alter our cells in such a way as to prevent viruses moving between cells, thereby preventing the spread of infection. All the data referred to in this paper is available online through the Pub Med database, free of charge. To see these yourself, simply search for Pub Med, then enter terms such as “antiviral essential oil”, “essential oil virus”, “essential oil immune” and the like. This is an excellent way to further motivate yourself to get the most from aromatherapy oil use.
Interpreting the Data: Many Oils vs. Many Viruses
With more than one hundred published research papers on the subject, a summary is in order. What scientists are finding is that many of the essential oils commonly in use today have antiviral properties. Whether an oil is effective against a particular virus depends upon the natural chemical makeup of the oil and the structure of the virus being studied. The data, without a doubt, is very encouraging. One study performed in Germany this year concluded with the note that Tea Tree was able to “reduce viral infectivity by greater than 96 percent”. The same study went on to clarify that the whole, natural oil, rather than any single chemical synthetically extracted, was up to TEN TIMES more effective as an antiviral agent. The precise reason for this is not known — it is clear that some of the most chemically complex oils exhibit the greatest antiviral effects, and perhaps this mixture of nature’s chemicals attacks the virus AND supports immune function is several ways at once.
One Pandemic Virus and The Oil of Laurel Leaf
Many of the studies utilize the Herpes Simplex Virus as a “test subject”, because of the widespread prevalence of infection, along with the relative ease of testing. However, if one digs into the data, many papers present information relevant in in influenza pandemic. SARS ‘Severe Acute Respiratory Syndrome’ is caused by the highly infectious SARS-CoV virus that made world-wide news in 2003. A study in the March 2008 Journal of Chemical Biodiversity noted Bay Laurel essential oil to have significant antiviral action against this virus. They’d also noted the natural constituents of this oil, which are also found in a great many other essential oils. This is why you’ll see MANY essential oils noted as antivirals — because many oils share similar natural chemical constituents. So while this next oil is not readily available, the data is very interesting. In 2005, Chinese researchers evaluated the anti-influenza potential of the essential oil from a root used in Chinese medicine, concluding: “In vivo…it prevented influenza virus-induced deaths in a dose-dependent manner”. And the list of oil/virus combinations goes on and on. But this begs the question: how do we derive a formula for Swine Flu prevention?
Selecting Oils For Daily Flu Protection
It is this sharing of natural compounds that supports the literature’s assertion that there are a great many oils in use today that are antiviral — one reason you’ll typically see several oils, not just one, in an antiviral formula. But which oils to use for your needs? This is where the long-time historical practice of aroma-medicine therapists helps us choose. The antiviral and immune-supportive essential oils have been categorized by the symptoms the infection produces. The Cineol-containing oils, like Eucalyptus and Ravensara are chosen where the bronchial system is affected. Melissa and Tea Tree are most commonly used for viruses infecting the skin — though their antiviral action for other parts of the body should not be ignored, because their synergistic effects with other oils creates a formula with a complex mixture of natural chemicals — similar in respect to the balance found in the single oil Bay Laurel. Other oils are highly regarded for their positive effect on the immune system overall: Frankincense is considered by some to be the most potent immunostimulant, and Melissa has this property as well.
A short list of essential oils that one can select from to support immunity against influenza infection includes the following: Melissa (having significant anti-HSV activity, it is also thought to be a potent immunostimulant — boosting the ability of our immune defense), Tea Tree (a very broad spectrum antiviral/antimicrobial), Rosalina (also known as Lavender Tea Tree, with a natural chemical profile containing constituents of both these oils), Lavender (commonly used as an anti-stress agent — which itself supports immune system function — and also having antiviral action), Bay Laurel (Laurel Leaf, reported effective against SARS-CoV), Ravensara aromatica, Eucalyptus Radiata (one of many Eucalyptus species, this one is most often noted as “antiviral”), Frankincense (considered by some the most effective immunostimulant oil available), Thyme, and Hyssop decumbens (a highly regarded antiviral, with a highly complex natural chemistry makeup).
Influenza Prevention Recipes
An example blend including these oils: 2 parts Melissa, 1 part Thyme (Thujanol, Geraniol or Linalool), 4 parts Lavender, 3 parts Ravensara, 4 parts Eucalyptus Radiata (Narrow Leaf), 3 parts Hyssop, 6 parts Rosalina (Melaluca ericifolia) and 3 parts Bay Laurel. A “part” can be anything — a milliliter, a drop, an ounce — just as long as they’re consistently the same volume. For children between 2 and 13, use 4 parts Lavender, 3 parts Rosalina, 1 part Ravensara, 1 part Eucalyptus and 3 parts Bay Laurel. This recipe is excellent as a lower-cost version for adults as well — and has been made more gentle for the young ones (consult Valerie Worwood’s “Aromatherapy for the Healthy Child” for more on using essential oils with kids).
Diffusing Your Oils for Best Results
The best way to use these oils is through diffusion, which is essentially “rapid evaporation”. A nebulizing aromatherapy diffuser will make a fine mist of essential oil which cleanly evaporates in your surroundings. This method allows a low concentration of the oils to be inhaled regularly. The effect is to actually disinfect the air in your home, as well as getting the oils into one’s lungs and bloodstream in small amounts. A feature of oils’ activity is that they are reported to reduce the ability of viruses to penetrate cell walls, so the lungs and sinuses become protected just by breathing the oil-infused air. Be careful not to overdo it though — the aroma should never be overwhelming or irritating, and your body will tell you if you’ve had enough. The oils do their immune-supportive job in subtle ways, which require only the smallest amounts of oil. The casual inhalation of the oils also gets them into circulation throughout the bloodstream, penetrating all the organ systems, and most importantly the lymph system — home to our immune function. A cold air nebulizing diffuser (as opposed to an ‘ultrasonic’, which dilutes the oils with water) would ideally be run 5-10 minutes every hour for this purpose.
Lymphs, Baths and Foot Rubs, Oh My!
Immune-protection topical oil blends can be easily mixed, putting the essential oil formula in a carrier oil such as Coconut or Jojoba. This concoction can then be massaged daily into the feet (a highly receptive area of the body) or into regions of lymph nodes: the neck, armpits and sternum. Adding the essential oils to a carrier at a 5 to 10% concentration is suitable (10% would be 1 part essential oil mixture to 9 parts carrier oil). If you’d like to use a topical formula for children, use the “children’s” recipe above, and lower the concentration in the carrier oil to 1% for ages 2-4, 2% for 5-7, 3% for 8-12 (a 1% concentration is 8 drops total essential oils in each fluid ounce of carrier, 2% is 16 drops per ounce, etc). Soaking in a bath with oils added to the water is also an excellent way to gain their benefits — for young kids, add 2 drops essential oil to a teaspoon of ANY carrier oil (olive oil from the kitchen will do fine), then swirl this into the bath once it’s been drawn. 4 drops essential oil blend for older children, and 6 drops for adults.
The Future of Aromatherapy: Aroma Medicine
While we cannot be certain of the direct effects of essential oils for our needs, it appears to the lay practitioner that the evidence supporting their use is just and solid as for any other natural medicine choice. Recall that the world’s leading aromatherapists suggest that it is in the prevention and treatment of infectious illness that essential oils will find their place in our medical systems. Given the data that so many essential oils offer antiviral activity against a variety of viruses, it isn’t out of the realm of possibility that they will be effective as Swine flu prevention. And with their relative ease of use, and ready availability, there’s little reason not to see what they may have to offer for you and your family.
