With the news of potential pandemic influenza prevailing the airwaves, many folks are turning to natural medicines to support their immune system. There’s great interest in protecting one’s self and one’s family from Swine Flu, Avian Flu and the like. Although there has not been any large-scale trials on influenza-prevention using natural methods, there IS a good amount of data on the anti-viral and immunostimulant activity of essential oils. (For those of you not in-the-know, essential oils are the concentrated, carefully-extracted volatile chemical constituents of plants and plant materials). Interestingly, it’s been the position of many of the world’s foremost aroma-medicine practitioners that the most medically important use of essential oils is for the treatment and prevention of infectious illness. Here’s a review of the scientific data, some suggested antiviral recipes, and instructions to use these oils for yourself and your family.
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 perfomed 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.
Bay Laurel and the SARS-CoV Virus
Because research is not yet available on the effects of oils against Swine and Avian influenza specifically, we need to make careful, logical conclusions from the data that IS available. For instance, the oil from Laurus nobilis (or Bay Laurel, the common cooking spice) was found to have antiviral action against the SARS-CoV virus — a highly contagious illness that made headlines as it spread around the world in 2003. A look at the aromatherapy literature notes that Bay Laurel has a highly complex makeup, containing molecules from nearly every one of the major classes of compounds found in essential oils. Hyssop is another oil also considered potently antiviral, again with a similar complex structure.
Choosing The Best Essential Oils for Influenza Protection
Here’s where we’ll make the leap from the scientific evidence to relying on many many years of Aroma Medicine practice throughout the world. In the aromatherapy textbooks, the list of antiviral essential oils is long. This corroborates with the scientific findings that a great many essential oils DO in-fact have antiviral activity. Where the help of skilled professional practitioners comes in is that in these texts, oils are prescribed by how effective they are against viruses that produce particular symptoms — respiratory tract infections are treated with cineol-containing oils such as Eucalyptus Radiata and Ravensara Aromatica. Viral infections of the skin are often treated with Melissa and/or Tea Tree. The doctors who have been using essential oils as medicine for years in Europe have developed a solid system, and can be relied upon in defining the appropriate list of oils for us.
A selection of potentially helpful essential oils includes the following: Melissa (also known as Lemon Balm), Eucalyptus Radiata (one of many kinds of Eucalyptus, this one specifically noted for its antiviral effects), Ravensara (similar to Eucalyptus, also a highly regarded antiviral), Lavender (don’t let its flowery aroma trick you — it is also considered antiviral and an immunostimulant), Maleleuca ericifolia (a relative of Tea Tree), Hyssop, Bay Laurel, and Thyme.
A Balanced Formula To Make At Home
A blend can be made using the following oils (and this complete formula can then be adapted to different applications as we’ll see): 1 milliliter (ml) Melissa, 1/2ml Thyme, 2ml Lavender (use Lavendula angustifolia), 1 and 1/2 ml Ravensara aromatica, 2ml Eucalyptus Radiata, 1 and 1/2 ml Hyssop decumbens, 3 ml Maleleuca ericifolia and 3ml Laurus Nobilis (Bay Laurel). A simpler, yet still effective formula with a more gentle nature — and more appropriate for children: 4ml Lavender, 3ml Melaleuca ericifolia, 1ml Ravensara, 1ml Eucalyptus, and 3ml Bay Laurel. While having a medicinal purpose, these blends do really smell wonderful as well.
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 oppposed to an ‘ultrasonic’, which dilutes the oils with water) would ideally be run 5-10 minutes every hour for this purpose.
Aromatherapy Baths and The All Important Foot Massage
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 “childrens” 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.
Conclusion: Essential Oils, Infectious Illness and the Future
As noted earlier, the world’s leading aroma-medicine practitioners believe the most important healing potential for essential oils is in the prevention and treatment of infectious illness. Of course, one should evaluate every available means of strengthening their immune system and those of their loved ones — there are many ways health professionals will recommend to do this. Considering the scientific data, essential oils are certainly a very worthy method of providing this support. Given all the contagions, Swine flu, Avian flu, and ones yet to be named, natural medicines have the long-term advantage of not being easily “adapted to” by viruses. The oils are so complex, and have evolved as the defense mechanism of plants over millions of years that they may present a far greater challenge to a virus to become resistant to when compared to synthetic preparations. And they’re such a joy to use — you’re house will be smelling fantastic while you’re keeping healthy; a great many amateur practitioners will concur that think you’ll find essential oils very worthwile.
