We source only pure essential oils.

Oregano is one of those oils that I keep on hand but rarely use.  It only comes out when I know I've picked up something ugly and really need immune system strength.  Why?  It stinks.  Of course, I never thought the herb smelled good either.  It's also a skin irritant — in a big way.  Dilution is important.  Too much of it in a diffuser can cause mucous membrane irritation.  What does that mean?  It means that, you may be using it to fight off something but your nasal passages get irritated and inflamed, causing you more discomfort than you already had.  When oregano essential oil comes out at my house, I add one drop to my diffuser and 1 drop to 5mL of a diluted blend that I apply 2-3 times during the day.  It's very important to patch test your dilution.  For most people, 1 drop in 5mL is fine but not everyone.

As to the many things I've read from people about using oregano essential oil internally or in steam bowls/cups . . . . do not do that with this oil without diluting it well!  This is a very strong irritant and both of those are playing with very tender membranes.  We do not believe that you should be taking essential oils internally without a qualified expert guiding you.  Trust me when I say that no qualified expert will guide you to take ANY essential oil internally without: 1) knowing your medical history and 2) proper dilution.  An expert knows which oils will interact with medications you're taking.  They know which oils will create problems with your own medical issues.  This oil has reasons in both of those areas that give an expert pause when recommending it.

Another way to utilize oregano essential oil during seasonal illness is to add a few drops to your green cleaning products.  It's high carvacrol tends to be effective against germs, making it a good addition to an all-purpose disinfecting spray.  Personally, due to the scent, I only do this when I'm desperate . . . and then I do it with an oil that helps hide the scent, like grapefruit, lemon, lime, or sweet orange.

Because it is warming, oregano can also be added to blends for achy muscles and joints.

Max topical use is 1.1%.  This is equivalent to approximately 2 drops of oregano essential oil in 10mL of carrier!  Dilute appropriately.

With our pre-diluted oils . . . if diluted for kids is the highest dilution you see, it’s also the max dilution possible. Pre-diluted oils are in fractionated coconut oil.

    I love the scent of oregano & it’s a favorite of mine to use in blends as an immune booster. I only use a drop or two, with other oils, on a personal inhaler or diffuser. It’s strong, so I only need a drop of two.

Oregano Essential Oil Safety Info

According to Tisserand and Young, oregano essential oil may inhibit blood clotting, may cause embryotoxicity, is a skin irritant when not properly diluted, and can irritate mucous membranes. Do not use if you’re pregnant or breastfeeding, you’re hypersensitive, have diseased or damaged skin, or with children under two years of age. This oil should be avoided orally if you take diabetic medication, take anticoagulant medication, are having major surgery, have a peptic ulcer, or have hemophilia or other bleeding disorders. Maximum topical dilution is 1.1%  Oregano essential oil should still follow the safety guidelines below. ~ Source:  Tisserand, Robert and Young, Rodney. Essential Oil Safety: A Guide for Health Care Professionals: Churchill Livingstone; 2 edition (2013). Reading the full profile for Oregano essential oil is highly suggested by your DeRu Staff.

While we’ve made this clear that we are selling this essential oil to use in your diffuser, your inhaler, or topically (diluted), it is a pure essential oil and can be used as such.  With all essential oils:

  • Never use them undiluted, in eyes or mucus membranes (this includes mouth, ear canals, noses, genital regions as well as internal areas).  The strength of essential oils can easily damage these soft tissue areas.
  • Do not take internally unless working with a qualified and expert practitioner.
    Keep away from children.
  • If applying an essential oil to your skin always perform a small patch test to an insensitive part of the body (after you have properly diluted the oil in an appropriate carrier).

  • Oral Safety is only given because many people have been told to take oils internally.  Because several people look to us for safety advice, we feel obligated to offer those safety statements, although we do not believe anyone should be ingesting essential oils without being guided by an expert.  Experts will take your medical history into account before they suggest oils for you to ingest, diffuse, or use topically.
