Lab Test Results
using Young Living Essential Oils for
MRSA, E-Coli and Acinetobacter Bacteria
One of our very skilled and credentialed team members, clinical microbiologist Mary Anne Mathewson from San Diego, did some testing in her lab a few months ago to check out several YLEOs for her neighbor's toddler who was diagnosed with MRSA, and whose parents had tried all sorts of medications to no avail. I wrote about it at the time, but was unable to transfer the pictures in her excellent report to e-mail. I have continued to work on it, and I believe you will now be able to receive the full report, pictures included.†
Many thanks to members like Mary Anne, who continue to prove to those who are not knowledgeable yet about the power of therapeutic-grade oils, just how potent and viable they are. I understand that Mary Anne's neighbor did use
Thyme successfully after seeing these test results.
Here is her report:
The Power of Young Living Therapeutic Essential Oils
I am a clinical microbiologist and have worked in hospital settings for the past 25 years. I have witnessed the steady increase in antibiotic resistant strains of various bacteria. The bacteria are able to quickly transfer resistance from one strain to the other. The resistant strains are not only hospital acquired, but are now found within the community; day care centers, military recruits, gym locker rooms, chronic care facilities. The New England Journal of Medicine April 7th, 2005 sites the growing prevalence of Methicillin resistant Staphylococcus aureus (MRSA) in cities across the US.
Some of the infections have been associated with necrotizing fasciitis.
There is an ever-increasing need for us to fortify our immune systems, as well as look to natural methods to support and protect our bodies and maintain the balance of nature. The bugs are outsmarting the drugs!
I chose to investigate the affect of therapeutic grade Young Living essential oils, all of which have been frequency tested. This means they must conform with the AFNOR (French Association of Normalization) standards for therapeutic-grade essential oils. These oils are steamed distilled at low pressure and temperature. This preserves the complex chemical constituents of the oils. The plants harvested have been grown on organic farms without pesticides, herbicides or fungicides and are free of any synthetic chemicals.
The oils I tested are
Thyme (Thymus vulgaris),
Oregano (Oreganum compactum),
Geranium (Pelargonium graveolens),
Tea tree (Melaleuca alternifolia) and
Thieves (a blend of clove, lemon, cinnamon, eucalyptus and rosemary).
I tested these oils with these three bacteria: Methicillin-resistant Stapylococcus aureus (MRSA), Escherichia coli (the most common cause of urinary tract infections), Acinetobacter calcoaceticus (cause of many nosocomial, hospital acquired infections).
A 1/2 McFarland suspension of each bacteria was made in tryptic soy broth. A blood agar plate was completely covered with the bacteria. A 50 microliter sample of oil, equivalent to one large drop, was inoculated onto each individual plate. Olive oil was used as a control. The plates were then incubated for 24 hours in a non-carbon-dioxide2 incubator. Pictures were taken after 24 hours. Four days later, measurements were taken of the area where there was no growth of the bacteria.
When viewing the pictures, note the white to gray area is bacterial growth.
Note: each oil caused inhibition of bacterial growth on the plate.
Area of Inhibition for MRSA:
Thyme = 100%; Oregano = 100%; Geranium = 1 3/4 inches;
Melaleuca = 1 1/2 inches; Thieves™ blend = 1 1/4 inches.
Area of Inhibition for E. Coli:
Thyme = 100%; Oregano = 100%; Geranium = 3/4 inch;
Melaleuca = 2 1/2 inches; Thieves™ blend = 1 1/2 inches.
Area of Inhibition for Acinetobacter:
Thyme = 100%; Oregano = 95%; Geranium = 1 1/8 inches;
Melaleuca = 7/8 inch; Thieves™ blend = 2.0 inches.
Thyme and Oregano are consistently the most effective in inhibiting the
growth of all three bacteria: MRSA, Escherichia coli, and Acinetobacter calcoaceticus.
Geranium is second in inhibition to thyme and oregano, when in contact with MRSA.
Melaleuca alternifolia is second in inhibition to thyme and oregano when in contact with Escherichia coli.
Thieves blend is second in inhibition to thyme and oregano when in contact with Acinetobacter calcoaceticus.
Bactericidal activity of the oils has not been verified, but this work shows the strong antibacterial powers
of two oils in particular; Thyme and Oregano. Each oil has unique chemical constituents.
These oils can be diffused, taken internally
in gel capsules and placed topically on the body, including the feet.
These two oils should be diluted 20-80
(one part essential oil to four parts vegetable or massage oil).
These findings confirm what is already in the literature.
Essential oils, the life-blood of the plant, are antibacterial.
These oils are Gods gift of healing to us.
- Thyme contains 59-90% alcohols and 12-21% monoterpenes.
- Oregano contains 60-80% phenols and 10-25% monoterpenes.
- These constituents contribute to their antibacterial activity.
