7 best essential oils for anxiety relief naturally

In Australia, more people are turning to natural therapies to manage everyday stress and anxiety. Whether it’s the fast pace of work, family pressures, or the lingering effects of the pandemic, there’s a growing shift towards gentle, non-invasive approaches that support mental wellbeing. Among the most popular options is aromatherapy, with essential oils taking centre stage in many households and wellness routines.

Essential oils work through the olfactory system—the part of the brain responsible for our sense of smell. When inhaled, these plant-based compounds send signals directly to the limbic system, a region linked to emotions, memory, and the body’s stress response. This connection is why certain oils can promote relaxation, ease tension, and even support better sleep.

For many Australians, essential oils offer a simple and natural way to create a sense of calm in daily life.

How essential oils help with anxiety

The connection between aroma and emotion is rooted in brain chemistry. When essential oils are inhaled, their scent molecules stimulate the olfactory bulb, which is directly linked to the limbic system—the part of the brain involved in mood, stress, and emotional regulation. This is what makes aromatherapy a fast-acting tool for calming anxious thoughts.

For those dealing with anxiety, essential oils may support the body’s ability to shift out of “fight or flight” mode and into a more restful state.

Some of the key benefits include:

• Calming overactive nervous system responses

• Lowering heart rate and blood pressure

• Easing physical tension and mental restlessness

• Supporting better sleep and overall relaxation

Scientific evidence backs this up. One study found that lavender essential oil reduced sympathetic nervous system activity, lowered blood pressure, and increased alpha wave activity in the brain—markers linked with relaxation and reduced stress levels.

7 Effective essential oils for anxiety relief

Essential oils can be a powerful part of your stress relief toolkit. Each oil listed below has unique benefits and ways to use it safely. From gentle florals to uplifting citrus oils, here are some options that may help ease anxious thoughts and support emotional balance.

1. Lavender (Lavandula angustifolia)

Lavender is one of the most popular essential oils for anxiety, known for its calming floral aroma and gentle sedative effect.

How it supports emotional wellness:
Lavender interacts with the limbic system to reduce nervous system activity. It may help lower heart rate, ease tension, and improve sleep quality. The oil contains linalool and linalyl acetate, which contribute to its relaxing properties.

Best ways to use it:

• In a diffuser: Add a few drops to help create a calming atmosphere, especially before sleep

• Topically: Dilute with a carrier oil and apply to pulse points such as the wrists or temples

• In the bath: Mix with a dispersant like Epsom salts or milk before adding to water

Safety considerations:
Lavender is considered safe for most adults and children. Always dilute for topical use and perform a patch test if you have sensitive skin.

Evidence-based support:
A study found that lavender oil reduced sympathetic nervous system activity and lowered blood pressure while increasing alpha wave activity in the brain, which reflects a relaxed state.

2. Roman chamomile (Chamaemelum nobile)

Safe ways to use essential oils for anxiety relief

While essential oils can provide effective support for anxiety, using them the right way is key to both safety and results. Here are some of the most popular methods and what to keep in mind for each one.

1. Diffusers and inhalation

Inhaling essential oils is a fast and effective way to trigger the brain's relaxation response.

• Add 3 to 5 drops to a diffuser with water for use at home or work

• Place 1 to 2 drops on a tissue or cotton pad and inhale during stressful moments

• Use in a well-ventilated area, especially if diffusing for long periods

This method is ideal for setting a calming mood in your space and can be part of your morning or evening routine.

2. Bath blends

Bathing with essential oils can help relieve both physical and mental tension.

• Mix oils with a dispersant like full-fat milk, honey, or Epsom salts before adding to bathwater

• Use no more than 4 to 6 drops in total to prevent skin sensitivity

• Soak for 15 to 20 minutes and follow with hydration or rest

Aromatherapy baths are especially helpful before bedtime or after a long, draining day.

3. Topical application

Applying diluted essential oils to the skin allows them to absorb slowly and support emotional balance throughout the day.

• Always dilute using a carrier oil such as almond, jojoba, or coconut oil

• A safe guideline is 1 to 2 drops of essential oil per teaspoon of carrier oil

• Apply to pulse points such as wrists, temples, behind the ears, or the soles of the feet

Topical blends can be part of a self-care ritual or used as needed during anxious moments.

Important safety tips

• Pets: Some oils, especially tea tree, eucalyptus, and citrus oils, can be harmful to pets. Avoid diffusing around animals unless you’re certain it’s safe.

• Pregnancy: Not all oils are suitable during pregnancy. Always consult a certified aromatherapist or midwife before using essential oils.

• Sensitive skin: Conduct a patch test when using a new oil to check for allergic reactions or irritation.

Staying informed about proper usage is essential. For more safety information, visit the Tisserand Institute’s Safety Guidelines, a reliable resource for both beginners and practitioners.
