The Complete List of Essential Oils for Allergies

(Last Updated On: August 3, 2018)

Essential oils are natural compounds which are extracted from the essence of a plant; from the seeds, barks, stems, roots, leaves, or flowers by a process of distillation. Essential oils give the plants their fragrance and assist in pollination.

Aside from this, essential oils have a rich history of being used in cooking, in beauty products, and as medicines.

They are useful in aromatherapy, as the oils travel through the air and are easily absorbed by the smell receptors in the nose. These receptors carry the scent to the brain, where mood, emotions, and behaviour can be affected.

Essential oils can be used alone or as a blend depending on what the user wants to achieve.

How to use an essential oil

Here are the most common ways of using an essential oil


We know that the smell receptors in the knows have a link to a part of the brain that processes memories, behaviour, mood, and emotions. This is why certain essential oils can have a beneficial effect on mood. Some oils are used to lift our mood and some are used to gain a calming effect. The oils can be put in a diffuser so they can fragrance a room, or you can simply put a few drops on a handkerchief or in the palm of your hand and inhale. You can also make a mist by mixing the oil with water, or using it to clean surfaces in your home.

Topical application

Essential oils are easily absorbed into the skin, and this is what makes them ideal for massages. Always dilute oils with a carrier oil before you use them on the skin, and it’s a good idea to test them on your upper arm to see if your skin reacts. Even if your skin doesn’t react, start off using a small amount of oil. You can add some oil to your bath, to a hot or cold compress, or add some oil to your favourite body lotion. Always avoid broken or damaged skin, the delicate eye area, and the ears.


Some essential oils are used in cooking or as dietary supplements. In cooking, they can add flavour and aroma, and when taken as a supplement, they can deliver targeted health benefits. The body can only handle a certain amount of the oils though, and as some can be toxic at certain levels, always make sure that you follow guidelines on dosage. You can add essential oils to water, smoothies, milk or tea.


Allergies are the body’s reaction to a substance. It might be something in the environment, something we eat, or something we apply to our skin. Allergies are quite common and they can affect one in four people. They are common in children, as their immune systems aren’t yet developed enough to react appropriately and proportionately to perceived threats. Adults can develop allergies in later life however, even if they weren’t previously allergic to the substance in question. Allergy symptoms can be troublesome, if they are mild, but severe allergic reactions can be life threatening.

Common allergies

The most common allergies that people suffer from are:
grass and tree pollen which causes misery every summer for sufferers.
dust mites
animal hair
foods such as nuts, shellfish, and milk
insect bites and stings
latex which is present in gloves and contraceptives
mould spores in the home
chemicals in detergents and hair dyes

Symptoms of an allergic reaction

Allergic reactions usually happen fairly soon after exposure to an allergen. If you have an allergic reaction, you may notice that you experience some or all of the following symptoms:

a runny or blocked nose
red, itchy, watery eyes
wheezing and coughing
a red, itchy rash
Though most allergic reactions are mild, occasionally a severe reaction called anaphylaxis can occur. This can be life-threatening and requires urgent medical treatment.
Anaphylaxis affects the whole body within minutes of exposure to an allergen.
Symptoms of anaphylaxis include:
swelling of the throat and mouth
difficulty breathing
blue skin or lips
collapsing and losing consciousness

Treating severe allergic reactions

Allergy Relief

People who are at risk of anaphylaxis are often given medication in the form of adrenaline in an EpiPen. In the event of a reaction, the adrenaline must be injected into the thigh as soon as possible and then medical help needs to be sought.

Treatments for allergies

Medications can help to control the symptoms of allergies. You will probably be prescribed the following medications if you suffer from an allergy.


These prevent the immune system from reacting so extremely, which is what causes the unpleasant symptoms.


These come in tablet form, capsules, nasal sprays or liquids and they can reduce the symptoms of a blocked nose which can occur with allergies.

Lotions and creams

These can reduce skin itching and sensitivity.

Steroid medication

These come in sprays, drops, creams, inhalers and tablets and they can help to reduce redness and swelling caused by an allergic reaction


For more severe allergies, a treatment called immunotherapy may be used. This involves exposing the patient to small amounts of the allergen over a period of years, so the immune system gets used to it and does not react so extremely.

What causes allergies?

Allergies occur when the immune system reacts to a substance as if it is harmful to the body. Many people with allergies also suffer from asthma or eczema. More people suffer from allergies now than ever before, and there is a theory that this is down to the fact that we live in a much cleaner environment now, so our immune systems aren’t as sharp as they might have been. They simply haven’t had enough germs to deal with to develop immunity.

Final Thoughts

They can be inhaled, from a diffuser or from a handkerchief, they can be added to your bath, or used in a massage

Essential oils are the essence of a plant. They are extracted from the bark, stems, roots, leaves, seeds, or flowers of a plant by a process of distillation. As well as affording the plant with protection, the natural oils give us a whole host of benefits too. They have a long history of use in medicine, beauty treatments, and cooking.

They can be inhaled, from a diffuser or from a handkerchief, they can be added to your bath, or used in a massage, or they can be added to food or taken as a supplement. There are many ways of getting the benefits from these natural wonders. Just remember though, that the natural compounds in the oils act like traditional drugs in that it is possible that they could interact with medication you are on, and many of them are toxic at certain levels in the human body. So seek advice, and start off with small amounts. This is also true if you intend to apply them to your skin. Do a patch test on the skin on your upper arm first then start off using a small amount of oil if your skin shows no signs of sensitivity.

Oils can be used for many things, and treating the miserable symptoms of allergies appears to be one of them. Allergy sufferers have to put up with a barrage of symptoms from runny noses, to itchy eyes and skin reactions. But there are some essential oils that can be inhaled, used topically, or used around the home to reduce symptoms and to keep your immune system in check. All natural solution, no chemicals required to overload an already delicate system.
