Top 10 Essential Oils for Allergies (& How to Use Them)

Over the last several decades, the rise in the prevalence of allergic diseases and disorders has continued in the industrialized world. Allergic rhinitis, the medical term for hay fever and what’s behind those unpleasant seasonal allergy symptoms we all know so well, develops when the body’s immune system becomes sensitized and overreacts to something in the environment. This is where essential oils for allergies can come into play.

When left untreated, allergies can cause a blocked and runny nose, sneezing, watery eyes, headaches, and an impaired sense of smell .. and this is in less severe cases. For some people, allergies can be life-threatening, leading to inflammation and shortness of breath.

People who suffer from allergies are often told to avoid triggers, but that is nearly impossible when the seasons are changing and our immune systems are impaired by the food industry and environmental toxins. Throw in that some allergy meds are linked to dementia and other scary health effects, and dealing with allergies becomes even more difficult.

Thankfully, some powerful essential oils serve as natural and safe ways to help treat the symptoms of allergies and boost the immune system. These essential oils for allergies have the ability to chemically support the body and help it overcome hypersensitivity.

How do essential oils fight allergies?

An allergic reaction begins in the immune system. An allergen is a substance that tricks the immune system, making it think that the allergen is an invader.

The immune system then overreacts to the allergen, which is really a harmless substance, and produces immunoglobulin E antibodies. These antibodies travel to cells that release histamine and other chemicals, causing the allergic reaction.

The most common causes of an allergic reaction include:

• Pollen
• Dust
• Mold
• Insect stings
• Animal dander
• Food
• Medications
• Latex

These allergens trigger symptoms in the nose, throat, lungs, ears, sinuses, and lining of the stomach or on the skin. The question here still remains: If these common causes have been around for thousands of years, then why have the allergy rates increased in recent history?

One of the theories behind explaining the increase in allergies has to do with inflammation, the root of most diseases. The body responds in a certain way to an allergen because the immune system is in overdrive. When the body is already dealing with high inflammation, any allergen sets off an increased reaction.

That means that when the body’s immune system is overworked and stressed, introducing an allergen sends the body into overreaction.

If the immune system and inflammation within the body were balanced, the reaction to the allergen would be normal. However, today these reactions are exaggerated and lead to the next unneeded allergic reaction in many people.

One of the most amazing benefits of essential oils is their ability to fight inflammation and boost the immune system. Essential oils for allergies help detoxify the body and fight infections, bacteria, parasites, microorganisms and harmful toxins.

They reduce the body’s susceptibility to outside sources and reduce the overreaction of the immune system when it is faced with a harmless intruder. Some exceptional essential oils even work to relieve respiratory conditions and increase sweat and urination, helping with the elimination of toxins and making them great essential oils for allergies.

Best essential oils for allergies

1. Peppermint oil

Inhaling diffused peppermint oil can oftentimes immediately unclog the sinuses and offer relief to scratchy throats. Peppermint acts as an expectorant and provides relief for allergies, as well as colds, coughs, sinusitis, asthma and bronchitis. It has the power to discharge phlegm and reduce inflammation, a leading cause of allergic reactions.

An in vitro study on human monocytes published in the European Journal of Medical Research suggested that peppermint oil treatment has anti-inflammatory effects reducing the symptoms of chronic inflammatory disorders, such as allergic rhinitis and bronchial asthma.

Remedy: Diffuse five drops of peppermint essential oil at home to unclog sinuses and treat a scratchy throat. This will also help relax the nasal muscles, enabling the body to clear out mucus and allergens like pollen.

To reduce inflammation, take one to two drops of pure peppermint essential oil internally once a day. It can be added to a glass of water, cup of tea or smoothie.

Peppermint oil can also be applied topically to the chest, back of neck and temples. For people with sensitive skin, it is best to dilute peppermint with coconut or jojoba oil before topical application.

2. Basil oil

Basil essential oil can help lower the inflammatory response of allergens. It also supports the adrenal glands, which are involved in producing more than 50 hormones that drive almost every bodily function.

Essentially, basil essential oil helps your body react appropriately to a threat by rushing blood to your brain, heart and muscles.

Basil oil also helps detoxify the body of bacteria and viruses, while fighting inflammation, pain and fatigue. Studies have proved that basil oil holds antimicrobial activity and can kill bacteria, yeast and mold that can lead to asthma and respiratory damage.

Remedy: To fight inflammation and regulate the overreaction of the immune system when faced with an allergen, take one drop of basil oil internally by adding it to soup, salad dressing or any other dish. To support the respiratory system, dilute two to three drops of basil oil with equal parts coconut oil, and apply topically to the chest, back of neck and temples.

3. Eucalyptus oil

Eucalyptus oil opens up the lungs and sinuses, thereby improving circulation and reducing symptoms of allergies. Studies have shown that it produces a cold sensation in the nose that helps to improve airflow.

Eucalyptus contains citronellal, which has analgesic and anti-inflammatory effects. It also works as an expectorant, helping cleanse the body of toxins and harmful microorganisms that act as allergens.

A 2011 study published in Evidence-Based Complementary and Alternative Medicine found that eucalyptus essential oil was an effective treatment for upper respiratory tract infections. Patients who were treated with eucalyptus spray reported an improvement in the severity of their most debilitating respiratory tract infection symptoms compared to participants in the placebo group.

Improvement was defined as a reduction of sore throat, hoarseness or cough.

Remedy: To treat respiratory issues associated with allergies, diffuse five drops of eucalyptus at home, or apply it topically to the chest and temples.

To clear the nasal passages and relieve congestion, pour a cup of boiling water into a bowl, and add one to two drops of eucalyptus essential oil. Then place a towel over your head, and inhale deeply for five to 10 minutes.

4. Lemon oil

Lemon oil supports lymphatic system drainage and helps with overcoming respiratory conditions. Studies have shown that lemon essential oil inhibits the growth of bacteria and boosts the immune system.

When diffused at home, lemon oil can kill bacteria and eliminate allergy triggers in the air. Adding one to two drops of lemon essential oil to water also helps with pH balance.

Lemon water improves immune function and detoxifies the body. It stimulates the liver and flushes out toxins that can lead to inflammation and an overreactive immune system.

Lemon water also stimulates white blood cell production, which is vital for immune system function because it helps protect the body.

Lemon essential oil can also be used to disinfect your home without depending on alcohol or bleach. It will remove bacteria and pollutants from your kitchen, bedroom and bathroom, reducing the triggers inside of your home and keeping the air clean for you and your family.

This can be especially helpful as the seasons change and allergens from outside are brought into your house on shoes and clothes.

Remedy: Add lemon oil to your laundry detergent, or mix a couple of drops with water and spray it on your couches, sheets, curtains and carpets.

5. Tea tree oil

This powerful oil can destroy airborne pathogens that cause allergies. Diffusing tea tree oil in the home can kill mold, bacteria and fungi.

It is an antiseptic agent, and it has anti-inflammatory properties. Tea tree oil can be applied to the skin to kill bacteria and microorganisms, and it can also be used as a household cleaner to disinfect the home and eliminate allergens.

A 2000 study conducted in Germany found that tea tree oil exhibits antimicrobial activity against a wide range of bacteria, yeasts and fungi. These microbes lead to inflammation and force the immune system to work on overdrive.

Remedy: Use tea tree oil on skin rashes and hives or as a household cleaner.

When using tea tree topically, add two to three drops to a clean cotton ball, and gently apply to the area of concern. For people with sensitive skin, dilute tea tree with a carrier oil first, like coconut or jojoba oil.

6. Lavender oil

Lavender oil is renowned for its calming and anti-inflammatory properties. Studies have revealed it may help prevent allergic inflammation and reduce mucous cell enlargement, making it beneficial during allergy season.

A human in vitro study published in BMC Complementary and Alternative Medicine investigated how lavender oil affects immune responses. Researchers treated human peripheral blood mononuclear cells (PBMCs) with lavender oil and observed a dose-dependent suppression of tryptophan breakdown via the enzyme indoleamine 2,3-dioxygenase (IDO).

This suppression led to reduced production of kynurenine, neopterin and interferon-gamma, molecules associated with immune activation and inflammation. These findings suggest that lavender oil may modulate immune responses by inhibiting pathways involved in inflammation, which in turn can help with allergies.

You can use lavender oil in a diffuser for aromatherapy or dilute it in a carrier oil for topical application.

Remedy: Diffuse five drops of lavender essential oil at home to alleviate allergy symptoms and promote relaxation. For skin irritation, dilute two to three drops of lavender oil with a carrier oil, and apply to the affected area.​

7. Frankincense oil

Frankincense oil possesses strong anti-inflammatory effects that can help soothe the respiratory system and reduce symptoms like nasal congestion and coughing. Its immune-boosting properties may also aid in preventing allergic reactions.

​A human clinical study published in Evidence-Based Complementary and Alternative Medicine examined the effects of inhaling a blend of essential oils, including frankincense, on symptoms of perennial allergic rhinitis (PAR).​ In this randomized, controlled trial, 54 adults with PAR were assigned to inhale either a blend of sandalwood, frankincense and Ravensara essential oils diluted in almond oil or a placebo (almond oil alone) for five minutes twice daily over seven days.

The study found that the aromatherapy group experienced significant improvements in nasal obstruction, quality of life and fatigue levels compared to the placebo group. The researchers attributed these benefits, in part, to anti-inflammatory compounds in frankincense, such as alpha-pinene, which may reduce allergic symptoms by modulating immune responses.​

These findings suggest that inhalation of frankincense-containing aromatherapy oil may serve as a safe and effective complementary intervention for alleviating symptoms of perennial allergic rhinitis, confirming its place among the top essential oils for allergies.​

Diffuse frankincense oil, or apply it topically with a carrier oil to the chest and neck areas. ​

Remedy: Add five drops of frankincense essential oil to a warm bath, and soak in it to help reduce allergy symptoms. Alternatively, inhale the oil directly from the bottle to clear sinuses and reduce mucus secretion.​

8. Chamomile oil

Chamomile oil has antihistamine and anti-inflammatory properties that can help alleviate allergy symptoms, such as skin irritation and nasal congestion. However, individuals allergic to ragweed or related plants should use it cautiously, as it may cause allergic reactions in sensitive individuals.

Remedy: Add a few drops of chamomile oil to a diffuser to help reduce allergy symptoms. For skin irritation, dilute chamomile oil with a carrier oil, and apply to the affected area.​

9. Sandalwood oil

Sandalwood oil is known for its anti-inflammatory and calming effects. It may help reduce symptoms of allergic rhinitis and promote relaxation.

In the study mentioned above on a blend that included sandalwood, Ravensara and frankincense oils, researchers suggested that the benefits observed may be attributed to the anti-inflammatory and immunomodulatory properties of the essential oils used, including sandalwood. Specifically, sandalwood oil contains compounds like alpha-santalol, which have been associated with relaxing and sedative effects, potentially influencing the autonomic nervous system and reducing hypersensitivity in the nasal mucosa.​

Use sandalwood oil in a diffuser, or apply it topically with a carrier oil to alleviate allergy symptoms.

Remedy: Diffuse five drops of sandalwood essential oil at home to help reduce allergy symptoms. Alternatively, mix sandalwood oil with a carrier oil and apply to the chest and neck areas.​

10. Ravensara oil

Ravensara oil has antiviral and antimicrobial properties that may help reduce the severity of allergic reactions. It is also known for its ability to support respiratory health and boost the immune system.

The researchers for the blend study mentioned in the frankincense and sandalwood sections suggested that the benefits observed may be attributed to the anti-inflammatory and immunomodulatory properties of the essential oils used, including Ravensara. Specifically, Ravensara oil contains compounds like 1,8-cineole and alpha-terpineol, which have been associated with anti-inflammatory effects by decreasing the production of inflammatory mediators.​

Diffuse Ravensara oil, or apply it topically with a carrier oil to the chest and back areas.

Remedy: Diffuse five drops of Ravensara essential oil at home to alleviate allergy symptoms. For respiratory support, dilute Ravensara oil with a carrier oil, and apply to the chest and back areas.​
