6 thoughts on “11 Powerful Eucalyptus Essential Oil Benefits

  1. Never knew there are so many uses for eucalyptus essential oil. It’s actually one of my wife’s favorite scents. My wife swears by eucalyptus and she said it really helps her hair grow faster. Do you think it really helps with hair growth, though?

    1. Hey Ahmed,

      Yes, eucalyptus can really help hair growth. Typically, you put it into your scalp with olive oil or coconut oil and massage it into the scalp. Leave it on for 30 min to 1 hour before you shower and it will stimulate blood flow. Then wash it off in the shower.

      It’s actually used in a lot of shampoos, too.

  2. I didn’t know that eucalyptus oil has so many different uses. I have it in a chest rub and drops to sniff for congestion relief. Need to try it for headaches as well.

    Is it also safe to use with kids? I have 3 to 7 years old. What’s the best way to use it when kids catch a cold?

    1. Hey Mary,

      You might not want to use eucalyptus on your 3-year-old. It’s not recommended to use it on kids younger than 6. The best way to use it is to boil it and add 7-10 drops in. Then you inhale the steam. However, since the kids are young you might want to just use it in the electronic diffuser. Also, you can make a rub out of it. Could use a carrier oil and or possibly lotion if you want to. Just make sure the dilution is 1% for kids. Rub it on their chest.

  3. Great article, I’ve used Eucalyptus since I was a child to help with my breathing when I get a ill and I swear by it, didn’t realize how many other uses it had!

    1. Hey Billy,

      It’s one of my “go to” essential oils for when I get all stuffed up and need relief from mucus, sneezing, coughing, etc. It really does work great!
