How to Take Oregano Oil

Now that you know why you should take oregano, you need to learn how you should take it.

Oregano oil is widely available in bottled liquid extract, capsule and tablet form; wild P73 oregano oil is the most potent. Please note that before you begin an oregano oil supplement, advice from a healthcare professional is strongly encouraged.


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.

  • 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.

    I’m not really big on taking supplements, preferring to get all my macro-nutrients, vitamins and minerals simply by eating a very healthy diet. But as a special case, every morning I take a single Oregano Oil cap (one that contains 32 mg of carvacrol per cap) because of its reputation for providing so many additional health benefits.

    My bother and I, both retired, live together, and this winter he came down with a really bad case of the flu, norovirus I suspect. He suffered with it for a couple of weeks, just couldn’t kick it, and I figured I would certainly catch it from him; but amazingly I never did. Doing some online research I stumbled across a reference to using oregano oil as a treatment for norovirus. Figuring it was at least in part the oregano oil that kept me from catching the flu from my bother, I suggested he give it a try. After taking three capsules per day for three days he finally got better, and now he too is continuing to routinely take one cap a day.

    Of course this hardly qualifies as proof that it was actually the oregano oil that made the difference in either of our cases, but it certainly reinforced my decision to continue taking it as part of my daily routine.

    I’ve had good success with oregano oil, but I can’t tolerate the taste of the liquid. Greg, what brand of caps do you like? I’d like to try that instead.

    I recently infused some oregano into olive oil. Didn’t plan on using it so soon but about the time it was ready for use, I came down with a UTI. I used 1/4 teaspoon x 4 daily for 10 days (number of days based on most antibiotic dosages. I am free of the UTI and now restarting the probiotics into my system since I am aware that antibiotic kill pretty much all bacteria good and bad. BTW…I like this better since I can put my dosage into my meals which makes it easier to take.
