When you catch a cold or are stressed out, most people look for support for their immune systems, like tonics. When it comes to health, paying attention to food, sleep and fitness is important and now essential oils are often included for stronger immune health.
However, does inhaling essential oils from plants really support your body fighting illness?
Answer lies in a mix of old traditions and new developments in science. Using essential oils has helped people clean air, soothe inflammation and aid the body in defending itself for hundreds of years. Recently, studies have started to reveal that some oils have antimicrobial, antiviral and immunomodulatory effects, so they play a strong role in self-care.
Here, we will discuss how essential oils might assist the immune system, name mentioned oils such as eucalyptus and oregano and give you tips on their safe and effective use.
How Essential Oils Support Immunity
Essential oils do not bring an immediate boost to the immune system like pills full of vitamin C or zinc. They help your body maintain its own defense system in several different ways:
- Antimicrobial Properties
A number of essential oils have terpenes, phenols and alcohols that are effective against bacteria, fungi and viruses. Chemicals in cleaning products help clean the air, surfaces and at times your skin as well. - Anti-inflammatory Effects
Chronic inflammation can impair immune function. Certain essential oils such as frankincense or ginger help reduce inflammation which brings back balance to the body and promotes better general health. - Respiratory Support
Eucalyptus and peppermint oils support airflow, helping you expel mucus which is best during seasons of cold, flu or allergies. - Stress Reduction
Chronic stress weakens immunity. Lavender and bergamot essential oils help relax the body and lower cortisol which weakens our immune response.
Essentially, essential oils help greatly with wellness by managing stress, purifying the air, reducing congestion and relieving inflammation. What are the oils most people turn to for immune support?
Top Essential Oils for Immune Support
Here are some essential oils that are supported by past and present studies for their help with immunity.
1. Eucalyptus (Eucalyptus globulus or radiata)
Why it works:
Many people know that eucalyptus oil has antiviral, antibacterial and decongestant effects. 1,8-cineole is found in it and has the job of opening airways, controlling coughing and lowering swelling.
How to use:
Allow it into the air by burning or letting it evaporate, add some to steaming water and breathe it in or mix it with a base oil and massage onto the chest or throat.
Great for:
Cold and flu symptoms, sinus congestion, respiratory infections.
2. Oregano (Origanum vulgare)
Why it works:
Oregano oil has strong antibacterial, antiviral and antifungal properties. It includes carvacrol and thymol which medical studies suggest block the spread of bacteria and viruses.
How to use:
As it is quite strong, oregano oil must be heavily diluted and can be safely used only in a diffuser or in a cleaning mixture. Consult a health professional before any internal use.
Great for:
Immune defense during flu season, surface disinfection, stubborn infections.
3. Tea Tree (Melaleuca alternifolia)
Why it works:
Many understand tea tree oil to be a strong disinfectant which means it can protect the skin from bacteria and viruses it may be exposed to. It also supports wound healing and reduces inflammation.
How to use:
If you like, drop a few on your cleaning sprays, laundry or diffusers. For skin use, dilute with a carrier oil.
Great for:
Topical skin protection, DIY hand sanitizers, air purification.
4. Lemon (Citrus limon)
Why it works:
It is the compound limonene in lemon oil that is responsible for its strong antioxidant, antimicrobial and detoxifying effects. It also supports lymphatic drainage, which helps eliminate toxins.
How to use:
If you want a clean scent around the house, add a drop to your natural cleaners or alternatively diffuse the oil.
Great for:
Cleansing the home, lifting mood during illness, gentle detox.
5. Frankincense (Boswellia carterii)
Why it works:
For many years, people have used frankincense in traditional treatments because of its anti-inflammatory and immune-boosting properties. Shallow breaths become deeper which relaxes you and helps you recover.
How to use:
Either use diffuse with calming music while meditating or at bedtime or add a few drops to a chest rub.
Great for:
Whole-body immune support, stress-related immunity dips, post-illness recovery.
6. Clove (Syzygium aromaticum)
Why it works:
Antioxidant content in essential oils is highest in clove oil. It helps against bacteria, viruses and fungi and supports both the circulatory and digestive systems.
How to use:
Mix with other oils when using them in aromatherapy vaporizers or homemade cleaning mixtures. For topical use, always dilute well.
Great for:
Seasonal immune blends, air purification, oral health support.
7. Ravintsara (Cinnamomum camphora)
Why it works:
Ravintsara, similar to ravensara, contains 1,8-cineole much like eucalyptus but it is milder and can be easily tolerated. It contains powerful antiviral properties and helps both the lungs and the immunity.
How to use:
Mix diluted oils in shared rooms or combine oils with carrier oil to massage on the chest.
Great for:
Colds, respiratory support, immunity in high-risk environments.
8. Thyme (Thymus vulgaris)
Why it works:
Thyme has begun to be famous for its antimicrobial qualities, as it contains thymol, supporting a fight against bacterial and viral infections.
How to use:
Best in diffusers or DIY cleaning products. Do not put undiluted oil directly on your skin and if using a diluted form, follow the instructions from a certified professional.
Great for:
Fighting airborne pathogens, blending with oregano and tea tree.
How to Use Essential Oils for Immune Support
Read on to find a few wise and safe ways to include essential oils in your daily schedule.
1. Diffusion
Pour 5–8 drops of your preferred oil (or blend) into the diffuser, then let it bring the aroma around you. The warm soup tastes great when it’s colder and when someone feels under the weather.
Blend idea:
- 3 drops eucalyptus
- 2 drops tea tree
- 2 drops lemon
- 1 drop frankincense
2. Steam Inhalation
Put 2–3 drops of eucalyptus or ravintsara in a bowl of hot water for respiratory relief. Lie face down over it, with a towel over your face and breathe deeply for a few minutes.
3. DIY Immune-Boosting Roll-On
Add 10ml of your favorite carrier oil (for example, jojoba or coconut oil) and 8–10 drops of oils you want to support your immune health. Massage the soles of the feet, the chest or the spine.
Blend idea:
- 4 drops frankincense
- 3 drops oregano
- 2 drops lemon
- 1 drop clove
4. Natural Cleaning Spray
Mix vital oils, vinegar and water in a bottle for an homemade disinfectant.
Recipe:
- ½ cup white vinegar
- ½ cup distilled water
- 15 drops tea tree
- 10 drops lemon
- 10 drops oregano
Shake well before each use.
5. Immune-Boosting Bath
Mix a few drops of essential oil (won’t be necessary if you already added carrier oil to the bath gel) with warm water, then soak for 15 to 20 minutes.
Having a bath with frankincense, eucalyptus and chamomile will soothe and refresh you.
Precautions and Safety Tips
Because they are strong, essential oils should be used with caution.
- Always dilute oils before applying to the skin.
- Do not take essential oils orally, unless given direction by an experienced aromatherapist or another qualified person.
- Keep away from eyes, ears, and mucous membranes.
- Use caution around pets and children. There are oils such as oregano and clove, that might overwhelm the systems of young or sensitive people.
- Check for interactions if you’re on medications or pregnant.
If you handle them carefully, essential oils can safely boost your health regime.
