5 Must-Have Essential Oils to Boost Your Immune System

5 Must-Have Essential Oils to Boost Your Immune System

You’re far more susceptible to the common cold, chest congestion, and the flu virus during the period between season changes. A low immune system can lack the support you need to bolster your body’s natural defenses and keep you healthy. If you’re like most people, you have too many tasks and too much work to stay in bed sick all day. As a result, your sickness tends to linger for days or weeks instead of healing itself promptly like it should.

Vitamins and minerals can help to boost your immune system’s natural response, but essential oils can also play a significant role in improving your overall health. These natural remedies can help keep your body at its optimal performance level year-round.

Instead of stocking your medicine cabinet with over-the-counter medications and supplements, why not try some of these natural approaches to preventing illness in the first place?  


Tea Tree Oil

Tea tree oil is an extremely versatile essential oil that has been recognized for its antimicrobial properties. This means that it tends to kill the various microbes and bacteria that interact with your body on a daily basis. You can diffuse tea tree essential oil in your work area or by your bedside to make good use of its immune-boosting properties.

It can also be used at the first sign of the common cold. Applying a couple of drops of tea tree oil mixed with carrier oil to your chest can help to clear your sinuses quickly. This is an effective decongestant and expectorant that can be applied regularly throughout the course of an illness. Instead of an over-the-counter cold medicine, you can try this home remedy to alleviate annoying symptoms.


Eucalyptus Oil

Have you ever felt extremely tired when you start to become under the weather? Exhaustion and fatigue are some of the most troubling symptoms when illness strikes. Not only is your mind unfocused due to the sinus congestion, but you feel too tired to power through it. You can use eucalyptus oil to help energize you and combat the symptoms simultaneously.

Similar to tea tree oil, diffusing eucalyptus will allow you to enjoy the decongestant and expectorant properties. However, if you can’t breathe the diffused oil in, you may struggle to enjoy all of the benefits. Mix two to three drops of eucalyptus oil with a ½ teaspoon of your favorite carrier oil and apply to your chest or the bottoms of the feet.

You may also add a couple drops of eucalyptus essential oil to a warm bath to soak in the immune-boosting properties.


Rosemary Oil

Do you need some immediate relief from a stuffy nose or a sinus headache? Rosemary essential oil may be able to help relieve some of these irritating symptoms quickly. It provides a great boost to your immune system and can loosen some of the mucus clogging your nasal passages. Of course, using it on a regular basis can help prevent illnesses in the first place. Diffusing it and applying it topically to your body daily are great ways to harness its immune-boosting potential. 

Pour two to three drops into the palm of your hands and rub them together. Then, cover your mouth and nose with your hands and attempt to breathe in. This is a great solution if diffusing the oil on its own isn’t providing a powerful enough solution.


Lemon Oil

Lemon essential oil can aid you in staying healthy during a rough season. This powerful essential oil is antibacterial and antiviral which can help make you less prone to the illnesses that travel through your school or workplace. You can allow this essential oil to work double-duty by using it as a household cleaner.

Mix ten to twenty drops of lemon essential oil with one cup of white vinegar and one cup of water in a spray bottle. This makes a great multipurpose household cleaner that can stop cold and flu germs right in their tracks. As an added bonus, you get the aromatherapy benefits associated with lemon essential oil while making your entire house fresher and cleaner.

Steaming with lemon oil can be a powerful way to clear your sinuses as well. In a pot of steaming water, add five to ten drops of lemon oil. Then sit back and inhale the steam while this essential oil works its magic on your sinuses.


Oregano Oil

Oregano oil can be a powerful ally when it comes to warding off the cold and flu. Much like the other essential oils on this list, oregano oil is antimicrobial and antibacterial which makes it great for eliminating viruses that make it through your immune system’s defenses. You can use it on a regular basis to help strengthen your immune system and prevent illness or use it to shorten the timespan that you’re sick.

You can mix this oregano essential oil with a carrier oil for a foot massage that can help to bolster your immune system. In one teaspoon of jojoba oil (or your carrier oil of choice), add three to five drops of oregano oil. Massage into the soles of the feet and cover them with cotton socks to allow the solution to absorb.

Diffusing oregano oil may also help to relieve the symptoms of the cold, including a stuffy nose and stubborn cough.


Nobody has time for a common cold to keep them tethered to their bedroom for days on end. Instead, you can use some of these robust essential oils to help energize and refresh you. They can assist you with everything from alleviating your symptoms to strengthening your immune system as a form of prevention against illness.

Next time you feel a cold coming on, why not reach for one of these natural remedies instead of an over-the-counter cold medicine? You could experience quick relief from your symptoms in a more natural way that’s just as effective with these essential oils.
