Oregano Essential Oil, Antibacterial Research

Oregano essential oil is one of the most powerful, potent essential oils

It is also one of the most researched, and has been found to be effective against bacteria including Staphylococcus, Giardia, Campylobacter jejuni, Escherichia coli, Listeria monocytogenes and Salmonella enterica to name a few.   Therapeutic Grade Oregano oil is steam distilled from the leaves of Origanum compactum.   Therapeutic, Food Grade Oregano oil also contains 60-75% Carvacrol, the active anti-microbial, anti-bacterial and anti-viral component that makes it so effective against microbes.   It has been researched for sinus infections, warts, respiratory diseases and fungal infections. Not all oregano oils contain this amount of Carvacrol, so it pays to read labels and do a little research on the potency of any oregano oil you use.

Oregano essential oil is packed with constituents that make it a powerful anti-inflammatory, anti-fungal, anti-parasitic and immune stimulating oil

An effective use of oregano essential oil for intestinal bacteria is to ingest it (Therapeutic, Food Grade  Oregano only) in gel capsules or to apply it to the skin.  Some supplements may contains 4 different species of oregano plus powerful thyme, cinnamon, clove, melaleuca & rosemary essential oil for powerful support for a healthy digestive tract. A healthy digestive system is a good defense against infections and viruses.  Oregano essential oil has even been tested against anti-biotic resistant bacteria.

Replace the Good Bacteria  Because oregano may be powerful against microbes, it also may disrupt your intestinal flora.  Only ingest oregano oil under the care of a doctor, and talk with your doctor about following up with a probiotic like to keep intestinal flora in balance.  It is also important not to overuse oregano oil (large amounts in a gel capsule), saving it’s strength for when your system really needs support, and only when under the counsel of an experienced practitioner.  It’s always best to support your body’s natural defenses with gentler oils like lemon first and save the potent ones for when you really need them.  Consult a doctor for specific usage of oregano essential oil.

Oregano oil is considered a “hot” oil and can be irritating if applied directly on the skin.  It should always be diluted with a carrier oil like a vegetable oil.  Oregano oil is one of 9 single and oil blends used in a Raindrop method for applying essential oils along the spinal column to boost your immune system.  It is also a strong smelling oil, so applying it to the soles of the feet or combining it with the other oils can make the scent less conspicuous.  I would not recommend diffusing oregano oil as it can irritate the respiratory tract and will penetrate fabrics and upholstery leaving an oregano scent.   If you want to purify the air in your home, a cinnamon/clove/rosemary/melaleuca/lemon blend is a better option with a more neutral aroma of cinnamon and cloves.

Oregano is an essential oil that has been around for thousands of years, it is powerful weapon against some serious strains of bacteria and definitely one worth having on hand during cold and flu season.  Oregano essential oil is potent and even 1 drop can support a healthy immune system.  When you use a food grade essential oil, you can add it to your recipes to stay healthy this winter.  Small amounts added into foods will keep you healthy this season without the effects of an antibiotic that disrupts intestinal flora.   Oregano oil is delicious when you use it in your favorite recipes. One of mine is Savory Butternut Squash soup in the Fall

    When trying to use as antibiotic to fight a sinus infection, how many times a day should I take? I have been putting two drops in a capsule and swallowing once a day. Can I do this more?

  2. Susan P January 26, 2013 at 8:44 pm #

    Oregano essential can be effective against a sinus infection. Since it’s a powerful antibiotic, I would not take it more than once a day if you have a sensitive digestive tract. I know some who have used it up to 3 times a day in capsules, less if you get an upset stomach. For sinus infections, our family has had good results from topical application of eucalyptus oils like the Young Living blends RC & Breathe Again Roll-on. Individual rosemary essential oil can be helpful too. Massage any of these oils around the sinuses and lymph glands in the neck making sure not to get any in your eyes. Oregano and thyme are hot oils and should not be applied to the delicate skin on the face or neck.

    Hi I read that OoO can help clear my Intersitual Cystitus. What dosage should I us? Should it be mixed with other oil for internal use?
    Thanks, Melody

    Hi Susan, I had a rot canal the other day and I think that area might be infected I took oregano oil by itself – filled a capsule – no carrier oil… Eek. It burned a little and I felt nauseous for just a minute but I drank a bunch of water and it went away…. So since I probably took10-20 drops, what do you suggest I do now, dosage and frequency-wise?

  5. Susan P January 23, 2014 at 8:13 pm #

    Hi Monica, any suspicious tooth infection should definitely warrant a visit to the dentist or your doctor. Oregano oil is a powerful antibiotic against many microbes, but not all. Good luck!

    Hi Melody, intersitual cystitis can be serious, you should seek the advice of a medical doctor right away. It can be helpful to connect with a holistic practitioner in your area to guide you for specific wellness questions. Best to you!

    I am so sorry to hear you are still in pain. I just read this and it may help (sooner than later). I hope this helps! http://articles.mercola.com/sites/articles/archive/2010/11/16/why-you-should-avoid-root-canals-like-the-plague.aspx
