How to Use Essential Oils for Immune Health

You can use these immunity boosting essential oils in a few different ways in aromatherapy or topically.  

It’s not recommended that you use any essential oil internally unless directed by your doctor or a trained aromatherapist.


Diffusing one or more of these essential oils can kill germs in the air, which can reduce your chances of getting sick. You can use three to five drops per 100 ml in your diffuser.

Always be careful to use oils that are safe around kids, pets, and pregnant women if they are in your home.

Personal Inhaler

If you have congestion and want to use oils to relieve your symptoms, you can use a personal inhaler. 

This is an excellent option if you want to use an oil that’s not kid safe or safe around pets.

Place 10 to 15 drops of essential oils or a blend onto the cotton wick. Inhale as needed for support. You can use one several times a day.

Room Spray

To kill germs in the air and get the aromatherapy benefits of the oils, make a room spray. 


  • 6 ounces distilled water
  • 2 ounces witch hazel
  • 30 drops essential oils


Place 2 ounces of witch hazel in an 8-ounce spray bottle. Add essential oils and shake to combine. Fill with distilled water.  

The water and oils will separate, so shake well before each use. 

Roller Bottle

Use a roller bottle to apply essential oils to your chest, wrist, or bottoms of your feet. (You may want to read this article on where to apply essential oils)

For a 5% dilution for short term use for adults, use up to 10 drops of essential oils for a 10 ml roller bottle.

Final Thoughts on Using the Best Essential Oils for Immunity

These essential oils for immune support are meant to support your immune system and are not a substitute for medical attention. Always consult a doctor if you need medical advice. 

Do not use essential oils topically without diluting them in a carrier oil like fractionated coconut oil or almond oil. See my section on How to Dilute Essential Oils for Topical Use. (Link below) 

Make sure the oils that you use are safe for those around you. Some oils can not be used on or around children, dogs, cats, pregnant women, or the elderly.
