bacteriaMany essential oils are tremendously antibacterial, anti-infectious, and antiseptic, yet completely harmless to healthy tissue. In fact, in most cases, they are highly beneficial to healthy tissue – a rare combination.

Jean Valnet, M.D., who studied essential oils and used them in his clinical practice emphasized their antimicrobial and beneficial properties:

“Essential oils are especially valuable as antiseptics because their aggression toward microbial germs is matched by their total harmlessness toward tissue.”

The problem with antibiotics

The problem with synthetic antibiotic drugs is that they indiscriminately kill both beneficial and harmful bacteria. This often results in diarrhea, yeast infections, poor nutrient assimilation, fatigue, degenerative diseases, and many other disorders.

The other problem with synthetic antibiotic drugs is that they composed of a single type of chemical. Bacteria and microbes quickly adapt and learn how to develop immunity to that chemical. Each drug is only effective on a limited number of germs or microbes – and those microbes tend to “figure out” and develop immunity to that drug very quickly.

Stronger and stronger drugs have to be used, but that doesn’t stop the bacteria. They continue to develop resistance to the stronger drugs, until there are no drugs left. This has given birth to a widening range of antibiotic-resistant superbugs that has become a serious health threat worldwide.

Why bacteria cannot outsmart essential oils

Essential oils, however, are composites of hundreds, if not thousands of naturally-occurring chemicals and constituents. Because of their complexity, bacteria and microbes might develop immunity to one or two constituents, but they cannot become immune to all of them. There are simply too many constituents and too much variety.

This is easy to understand when you know that no two batches of oil are exactly the same. The levels of each constituent varies according to the season, the weather, the soil, the amount of sunshine received, where they are grown, the time of year and even time of day they are harvested. Because there are millions of combinations and variations in the oils, there is no way bacteria can outsmart them. Germs, bacteria and microbes are left defenseless.

Please understand, we are not talking about the inexpensive essential oils you find at the drug store or health food store. This effect only occurs in the highest quality, naturally grown essential oils.

Which oils are the most effective?

Two essential oils with the most antibacterial, anti-infectious, and antimicrobial properties are cinnamon and oregano. In l985, Dr. Jean C. Lapraz stated that, according to his research, no microbe could survive in the presence of the essential oils of cinnamon or oregano. Thyme, mountain savory, melaleuca, ravensara, rosewood, and eucalyptus radiata are others.

Essential oils can also be combined into blends, to create an even more powerful antimicrobial oil. Some of these blends are Thieves, Exodus II, ImmuPower, Melrose, Inspiration and Sacred Mountain.

The Thieves blend of clove, lemon, cinnamon and rosemary was tested at Weber State University and found to dramatically inhibit the growth of many difficult to control bacteria including Micrococcus luteus and Staphylococcus aureus (both gram negative and gram positive).

The same blend exhibited an astounding 99.96 percent kill rate against one of the toughest gram negative bacteria, Pseudomona aeruginosa, as well as Streptococcus oralis, Streptoccus pneumoniae, and Candida albicans. Pseudomona aeruginosa has thicker cell walls than most bacteria and tends to be much more resistant to antiseptics.
