Everyone has likely seen eucalyptus used in floral arrangements. It is fragrant, eye pleasing and a versatile filler. Eucalyptus has so many other applications in essential oil form. An effective home remedy to many common maladies you could be suffering with.

Essential oils are widely used as home remedies in today's society. But first you need to know how to use them, and what afflictions they can remedy. In this article I will cover some common uses of eucalyptus oil and how to apply it for each.
Common uses of eucalyptus essential oil include:

  • pest deterrent
  • lice treatment
  • fever reducer
  • muscle pain relief
  • respiratory infections

Pest Deterrent

Eucalyptus is a very effective pest deterrent. Mixing a solution of eucalyptus can even kill certain pests on contact. In my younger years my mother even used eucalyptus to keep our cat out of certain areas of the house.

How to Make Eucalyptus Pest Spray

  • 100 drops eucalyptus oil (equal to a teaspoon)
  • 2 cups of water
  • mix together
  • store in a spray bottle
  • Shake well before use

This spray is easy to make and will help you deter and even kill pests. The follow pests are often killed instantly with eucalyptus oil:

  • earwigs
  • mites
  • whitefly
  • aphids

There are many other pest control uses for this oil too. You can expect to protect your garden plants against:

  • Mushroom flies
  • Rice weevils
  • caterpillars

Of course if you need to keep your cat out of specific areas, this oil works well for that too. Cats just seem to hate the smell, so keeping kitty out of your rose bush is easy.

Eucalyptus is generally deemed non-toxic to humans, as such it makes a great pest repellent and beneficial in helping garden plants remain pest free. Unless you have any diagnosed allergies to eucalyptus this repellent spray can be directly applied to any infested garden plants.

Dealing with a lice outbreak is stressful. Once it was common to cut an infested persons hair short as part of a treatment. We now know there are other alternative treatments.

Lice Treatment

Lice treatment, I'm sorry this one likely has you scratching already. As I write this the subliminal urge to begin scratching my scalp is hard to resist. No one wants lice, no one wants to deal with treating for it, but it happens. Frequently passed between elementary aged children, almost all of use have to deal with lice at some point.

Eucalyptus oil can be used as a lice treatment and preventative as well. Be cautious with all oils especially when treating your younger family members or children. A small skin test with diluted oil is always recommended prior to using any treatments. A small spot that has an allergic reaction is easier to deal with. Jumping in with a full blown treatment and dealing with a widespread allergic reaction is not fun for anyone.

Lice Treatment Recipe

  • 2 ounces carrier oil (olive oil will work)
  • 15-20 drops eucalyptus oil
  • mix thoroughly
  • apply to scalp
  • leave on hair at least 12 hours
  • comb out hair then wash and rinse

You can repeat the process as necessary to control a lice outbreak. Wrapping the hair while the mixture remains on is beneficial. Especially if doing an overnight treatment, this will keep bedding from being oil stained.

For a preventative measure when the dreaded 'we have lice in our classroom' letter comes home from school add 5-10 drops to shampoo. Shampooing daily will help possibly deter the louse from choosing your child for their next host.

Fever Reducer

If you are experiencing a low grad fever try adding a few drops of oil to a compress. Lay the compress across your forehead, a cool compress is best. Be sure if your fever is high and you cannot seem to get it under control that you seek medical attention if warranted.

At home I generally try home remedies for fever reduction. We as parents can often overload clinics and doctors offices for low grade fevers. Fevers are actually natural and serve a purpose.

A good rule of thumb for visiting the doctor for fevers is:

  • If a fever is 103°F or higher.
  • The fever has lasted more than 3 days.

In most cases we can reduce fever symptoms at home, either with home remedies or over the counter medicines. Fevers are actually a good thing, it is our bodies response to rid us of illness. Allowing fevers to do the natural thing, and create an environment that is hard for bacterial and viral infections to thrive in. I often don't treat low grade fevers and let them run their course. Allowing the body to do what it was meant to do.

Muscle Pain Relief

For muscle pain relief use 5 drops of eucalyptus to 2 tablespoons of carrier oil. Coconut oil is a good choice, it remains solid at room temperature. Using coconut oil is my personal preference as I find it to be less messy during application.

To use coconut oil you can warm in the microwave or stove top and then add your oils. Once it cools down it will re-solidify. Massage into any sore muscle, sprains or even just annoying regular aches and pains.

Many drugstore solutions for cough and repository issues contain eucalyptus oil.

Respiratory Infections

Eucalyptus oil is very effective home remedy for treating respiratory issues and bad coughs. Those suffering asthma, bronchitis or just a cold or flu associated cough can use it as a home remedy. There are a few ways to use it for this application.

  • Mix a few drops of eucalyptus with a tablespoon of carrier oil and use as you would a vapor run. Applying to the chest and back.
  • Dilute 5-10 drops in boiling water and inhale the steam.

Using eucalyptus in an inhaled steam will react with the mucus membranes. Effectively loosening mucus so it can be expelled when you cough. It will also lessen mucus production.

It can often reduce asthma symptoms but it should not replace any rescue inhalers you have. Eucalyptus is actually an active ingredient in many over the counter cough suppressants and rubs. Using a home remedy you made yourself is a more cost effective solution to pricey name brand products.

Please always use caution when attempting home remedies for the first time. While most people do not have reactions to oils, always do a small skin test with a dilute oil prior to using a remedy.

Final Thoughts and Precautions

We have arrive at the disclaimer portion of this article. Please be sure that you really look into the oils you are using. Not all oils are meant for use in remedies. Some essential oils available on the market today are not organic or therapeutic grade. Many oils you can purchase are meant for fragrance use only.

Due diligence in choose an oil by doing research is required. When using oils, make sure you also do a test. And always dilute essential oils in a carrier oil. Using essentials 'neat' or not diluted can cause contact dermatitis.

I use SVA Organics eucalyptus oil, it is a 100% natural organic oil, and therapeutic grade. Most of my oils I use currently are from this brand. No matter what brand you settle on, please be sure it is a quality oil suitable for home remedy applications.

      Cynthia, I love the smell of eucalyptus. I like the idea of using it as a pest deterrent in the garden, since I don't use pesticides or other toxic chemicals in my yard.

      Thanks for the tips!
