How Powerful is Oil of Oregano?

For those who want to see what the scientists say, there’s a study in the Journal of Applied Microbiology in which researchers exposed a mouse norovirus (a human norovirus surrogate) to oregano oil and carvacrol. Both treatments were effective against the virus, but carvacrol was better, inactivating the virus within one hour of exposure.  If you want to help prevent the spread of cold and flu viruses on your hands and household surfaces, then you may want to use liquid soap that contains oregano essential oil or add the oil to an all-natural brand you are using now. An investigative team looked at the use of liquid detergent solution with added oil of oregano (0.5%) and found that it was as effective as a commercial antimicrobial soap, but without the harmful ingredients such as triclosan and chloroxylenol (and since the FDA recently banned many antibacterial chemicals why not make a safer homemade alternative?

The general dosing for oil of oregano for adults is 2 to 3 drops three to four times daily once you have a cold or flu. For preventive or maintenance purposes, take 2 to 3 drops twice a day. If you choose to take supplements, use 100 to 150 mg capsules in place of the 3 to 4 doses daily. To treat a sore throat, you can add 5 to 6 drops of oregano oil to a glass of water and gargle several times a day (I like to place the drops directly in my throat so I’m sure it is doing its magic!).


For athlete’s foot, submerge the affected area in a bath containing a few teaspoons of the oil.

For skin conditions and nail fungus, dilute the oregano oil with 100 percent pure olive oil at a rate of 1 teaspoon of olive oil per drop of oregano oil and apply the mixture to the skin and nails.


Dilute the oregano oil with 100 percent pure olive oil at a rate of 1 drop of olive oil per 1 drop of oregano oil. Use a sterilized dropper bottle. Drop 1 to 2 drops of the diluted oil under the tongue and hold it there for a few minutes; then flush with water. You can gargle the water with a few drops of oregano oil for a few minutes and then swallow.

You need a dosage of 500 mg, four times per day, to achieve the antimicrobial benefits. Therefore, if you are taking oregano sublingually or gargling it, be sure you do this several times per day to be sure you are receiving an adequate dosage.


To fight sinus infections, colds and allergies, add a few drops of oregano oil to a small pot with boiling water. Cover you head with a towel, close your eyes and put your face over the pot (but not close enough to get burned); inhale the steam. Repeat several times to clear the throat and nasal passages.


For acute infections, you need approximately 500 mg, four times per day, to achieve the antimicrobial benefits. However, since different manufacturers have different amounts of the active ingredients – caravacrol and thymol – in their particular brand, it is helpful to follow the manufacturer’s instructions.

For more serious chronic conditions, it is best to seek the advice of an integrative physician. In these instances, an integrative physician may recommend a very high dose of the oil.

Oil of oregano can be given to children, although the strong taste makes convincing them a challenge. Fortunately there are oregano oil supplements specially formulated for youngsters (including natural mint oil to mask the taste of the oregano), and they should be dosed as recommended by the manufacturer. You can also add a couple of drops of the liquid to the bottom of their feet and then cover with socks to trap the vapors. We call this “pizza feet” in our house.

You also can add a few drops of the oil in a diffuser or vaporizer to help clear up a stuffy nose and sinuses. Breathe in the pleasant aroma for a few minutes several times a day.


  • Oregano can cause reactions in people allergic to Lamiaceae family plants, including basil, hyssop, lavender, marjoram, mint, and sage.
  • If you are taking prescription medications, do not start oregano oil without consulting with your doctor or an integrative physician first.
  • You should limit your use of oregano oil to only 7 to 10 days. Oil of oregano is not recommended for infants, pregnant women, women who are breastfeeding or anyone who has high blood pressure or heart disease.
