EDUCATE:
I found this information to be very intriguing.  Young Living's Thieves essential oil blend was diffused in scientific tests against air- borne bacteria at Weber State University with up to a 96% reduction in 1997.
 
Airborne BACTERIA COUNT(CFU) STARTING AT 0 TO 4500
1.  With the bacteria of M. Luteus it was around 4100 and after using Thieves the count dropped to around 700

Micrococcus luteus is a Gram-positive, spherical, saprotrophic bacterium that belongs to the family Micrococcaceae.[1] An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal flora of the mammalian skin. The bacterium also colonizes the human mouth, mucosae, oropharynx and upper respiratory tract.  Considered a contaminant in sick patients.M. luteus is resistant to reduced water potential and can tolerate drying and high salt concentrations.

2.  With P. aeruginosa it was around 2000 and after using Thieves it dropped to 1

Pseudomonas aeruginosa is a common bacterium that can cause disease in animals, including humans. It is found in soil, water, skin flora, and most man-made environments throughout the world. It thrives not only in normal atmospheres but also in hypoxic atmospheres, and has, thus, colonized many natural and artificial environments. It uses a wide range of organic material for food; in animals, the versatility enables the organism to infect damaged tissues or people with reduced immunity. The symptoms of such infections are generalized inflammation and sepsis. If such colonizations occur in critical body organs, such as the lungs, the urinary tract, and kidneys, the results can be fatal.[1] Because it thrives on most surfaces, this bacterium is also found on and in medical equipment, including catheters, causing cross-infections in hospitals and clinics. It is implicated in hot-tub rash. It is also able to decompose hydrocarbons and has been used to break down tarballs and oil from oil spills.[2


3.  With S. aureus it was around 2300 and after using Thieves it dropped to 1000.

Staphylococcus aureus/ˌstæfɨlɵˈkɒkəs ˈɔri.əs/; meaning the "golden grape-cluster berry," and also known as "golden staph" and Oro staphira, is a facultative anaerobic Gram-positive coccal bacterium. It is frequently part of the skin flora found in the nose and on skin, and in this manner about 20% of the human population are long-term carriers of S. aureus.[1] S. aureus is the most common species of staphylococci to cause Staph infections. One of the reasons for this is a carotenoid pigment staphyloxanthin that is responsible for the characteristic golden colour of S. aureus colonies. This pigment acts as a virulence factor, with an antioxidant action that helps the microbe evade death by reactive oxygen species used by the host immune system.[2][3]

S. aureus can cause a range of illnesses from minor skin infections, such as pimples, impetigo, boils (furuncles), cellulitis folliculitis, carbuncles, scalded skin syndrome, and abscesses, to life-threatening diseases such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS), chest pain, bacteremia, and sepsis. Its incidence is from skin, soft tissue, respiratory, bone, joint, endovascular to wound infections. It is still one of the five most common causes of nosocomial infections, often causing postsurgical wound infections. Each year, some 500,000 patients in American hospitals contract a staphylococcal infection.[4]

Methicillin-resistant S. aureus, abbreviated MRSA and often pronounced "mer-sa", is one of a number of greatly-feared strains of S. aureus which have become resistant to most antibiotics. MRSA strains are most often found associated with institutions such as hospitals, but are becoming increasingly prevalent in community-acquired infections. A recent study by the Translational Genomics Research Institute showed that nearly half (47%) of the meat and poultry in U.S. grocery stores were contaminated with S. aureus, with more than half (52%) of those bacteria resistant to antibiotics.[5]



THE EFFECT OF TIME ON BACTERIA COUNTS when diffusing Thieves:

THE BACTERIAL COUNT (CFU) 0 TO 10000

1.  Bacteria starting out at 10000 at zero minutes

2.  After 3 minutes of diffusing it dropped to 5000

3.  After 6 minutes of diffusing it dropped to 800

4.  After 9 minutes  of diffusing it dropped to 2

5.  After 12 minutes  of diffusing you can hardly see it.

EMPOWER:  From the above studies it's easy to see the importance of using a Young Living  diffuser specially designed to force a micro-fine mist into the air.

The smallness of the mist allows your essential oils to stay in the air longer, which gives the essential oil a greater chance of coming into contact with odors, germs, bacteria and mold. When that contact occurs, the essential oils can do their thing at neutralizing and killing them!

 
ENJOY:  The smell of Thieves is very inviting in the home.
