A total of 91 Young Living single essential oils, and 64 Young Living blends were tested for their inhibitory activity against methicillin-resistant Staphylococcus aureus (MRSA) in 2008. Of the 91 single Young Living essential oils 78 exhibited zones of inhibition against MRSA. And of the 64 Young Living blends 52 exhibited inhibitory activity against MRSA.

Since the 1950s, the Centers for Disease Control and Prevention (CDC) have reported that the proportion of overall staphylococcal infections due to MRSA has risen steadily from 2% in 1974, to 22% in 1995, to 63% in in 2004[1] in the USA. Although initially most MRSA infections were acquired in hospital (HA-MRSA) settings, the first appearance of a community-acquired MRSA (CA-MRSA) occurred in 1982 among intravenous drug users in Detroit.[2]
Since 1982 CA-MRSA (Community Acquired -MRSA) has grown annually into an ever-increasingly source of infections among individuals previously labeled as belonging to ‘low-risk’ groups.
Since cases of HA-MRSA and CA-MRSA are increasing, as are the rates of antibiotic therapy failures, many have been searching for new methods of prevention and treatment.[3-6] Research has revealed some promising novel antimicrobial candidates including superior quality essential oils, such as Young Living’s.
In vitro data indicate that many Young Living essential oils have antimicrobial activity.[7] The activities that were investigated and their actions against various pathogens, including MRSA, were demonstrated. [8-14]
There are also several clinical studies [15, 16] and case reports [17, 18] noting the successful use of YL essential oils in treating MRSA nasal carriage or MRSA infections. Specifically, Dryden et al.[15] and Caelli et al.[16] reported that topical YL tea tree (YL Melaleuca) was effective as standard therapy for reducing MRSA nasal colonization; Sherry et al.{17, 18] reported successful treatment of patients with staphylococcal wound infections. However, several review articles[17, 18] have reported that, while use of essential oils as antimicrobial agents is promising, additional in vivo studies and more clinical studies involving larger numbers of subjects are needed.
Previous studies done in the YL lab have shown inhibition of Streptococcus pneumoniae and other pathogens by various YL essential oils, but these oils were not tested specifically against MRSA.[7, 22, 23] Thus, this study was initiated to screen YL essential oils for inhibitory activity against medically important bacterium to determine their potential as candidates for use as disinfectants, antiseptics, or topical treatments against MRSA.
The Results of the Young Living Single Essential Oils
Of the 91 YL single essential oils that were screened by the disc diffusion assay, 78 had measurable inhibitory activity, while 13 exhibited no detectable inhibitory activity against MRSA.
Of the YL single essential oils tested, lemongrass, lemon myrtle, mountain savory, cinnamon bark and melissa showed the highest levels of inhibition. 
Remarkably, the YL essential oil lemongrass (60 mm) completely inhibited all MRSA growth on the plate.
Significant zones of inhibition (45-57 mm) were found for these other YL essential oils: thyme, cumin, Eucalyptus citriodora, tsuga, oregano, Melaleuca arternifolia.
Intermediate inhibition zones (35-42 mm) were detected for the YL singles of: ledum, Eucalyptus dives, niaouli, manuka, peppermint, elemi, and rosewood.
Results of the Young Living Essential Oil Blends
Of the 64 YL blends tested, 52 showed zones of inhibition, while 12 showed no detectable inhibitory activity against MRSA. 
Of the YL blends, the blend called R.C. scored the best, with the blends Motivation second, Longevity third.
An Observation
It was noted that the single essential oils that showed little or no detectable zone of inhibition when combined with other singles can produce significant zones of inhibition, suggesting a ‘synergy’ is occurring between the essential oils. For instance, the blend ‘Motivation’ showed anti-MRSA activity greater than the individual single oils when tested alone. Thus, the diameter of the zone of inhibition is greater than would be expected if the effect was only due to the YL oils acting independently. Likewise, the data for the other two YL blends, R.C. and Longevity, imply synergism of the combined single oils in the blends.

Preventing Staph Infections: what I like to do
Whenever possible I like to practice ‘prevention.’ A perfect example occurred this past spring when I seriously injured my foot and ankle and had to go to the Emergency Room. Here’s what I did because it was convenient…
I took a bottle of my Thieves Waterless Hand Sanitizer and added to the 1 oz. bottle 7 drops of Lemongrass essential oil, and shock it up good.
Prior to getting out of the car, both Curt and myself squirted a nickel size dab of the Thieves hand sanitizer in our palms and rubbed it in well being sure to cover all parts of our hands.
After my blood-pressure was taken (on my bare arm and that little thing they put on your finger), Curt put a nickel size dab in his palm and rubbed it around my arm where the cuff had been located, and he squeezed a dab into my palm so I could rub the Thieves hand sanitizer (with lemongrass included) over my hands again. 
The doctor looked at and touched my calf, ankle and foot. I also had X-ray’s where my foot again was touched – both times by hospital staff who did NOT wash their hands prior to touching me.
A side note: I ‘intentionally’ didn’t ask anyone to wash their hands before touching me because I planned to slather myself with my Thieves sanitizer after anyone touched me and I wanted to see how many would actually wash their hands without my asking. However, I HIGHLY recommend that you do not do this and always ask doctors, nurses, and ALL hospital staff to thoroughly wash their hands in front of you before they touch you – if they have MRSA on your hands or if you touch someone of something that has MRSA on it you can become infected.
After leaving the Emergency Room, but before opening the door of our car, Curt and I again paused to do our dabs of Thieves hand sanitizer – didn’t want to risk getting any cooties on the surfaces of the car.
As a general rule, I always carry a bottle of Thieves Waterless Hand Sanitizer in my purse, and keep one in the car – both have several drops of lemongrass added. We apply a dab prior to getting out of the car, particularly so when we will be touching things that many others have touched – like gas pump handles, door handles, shopping carts (which are extremely filthy! I do NOT recommend putting your purse, food or items in the child seat of the carts as they are loaded with bacteria, urine, and feces – studies have shown).
MRSA never really goes away once you acquire it and it can affect the rest of ones life on many levels. I’ve read some extremely sad stories about how people have been treated like lepers, lost their jobs, have been ostracized by their neighbors, etc. – I personally prefer to look like I might have a phobia than to risk having changes like that for the rest of my life.
What I would do if I were in a Nursing Home or staying in a Hospital
You better believe I would bring my Young Living Nebulizer Essential Oil Diffuser, a bottle of R.C. and a bottle of Lemongrass – and – my Thieves Hand Sanitizer (with several drops of either lemongrass or R.C. added to it). I would also bring these items in to these places if a loved one were there and leave them for that individualal to use as needed.
Fabrics Harbor MRSA (studies show)
To address this, I would use my Thieves Household Cleaner in the laundry (one capful per load in place of laundry detergent) and I would add a few drops of lemongrass to the load.
If MRSA were in My Home
If I were in a situation where MRSA were in my home or on people living in my home – I would do ALL of the above regularly.
Normally, I regularly diffuse my oils, use Thieves Household Cleaner for all of our laundry, and only use my Young Living oils to clean my house and surfaces.
