Lemon Myrtle Essential Oil Benefits and Uses

Lemon myrtle essential oil has a light, citrusy scent and a range of uses in aromatherapy, cleaning, skincare, and first aid. It is prized for its high citral content, the compound responsible for its lemon-like aroma and many of its antimicrobial effects. Because it is potent, a little goes a long way.

What Is Lemon Myrtle Essential Oil?

Native to subtropical Australia, lemon myrtle (Backhousia citriodora) is also called sweet lemon verbena or lemon-scented myrtle. The oil is steam-distilled from the leaves.

Its chemistry is rich in citral, a natural mixture of geranial and neral. Citral acts as an antiseptic and is known for its lemon fragrance. This explains why lemon myrtle is often used where a clean, fresh scent is desired.

Because it is strong, only a few drops are needed for most uses, whether in a diffuser, a room spray, or a carrier oil blend.

Potential Benefits

Studies suggest lemon myrtle has antimicrobial and antifungal activity in laboratory tests. This means it can help reduce some bacteria and fungi on surfaces or skin when used appropriately.

Its bright scent also makes it useful in aromatherapy. Research on citrus and citrus-like essential oils indicates mood benefits such as reduced feelings of stress and improved alertness, although effects vary between people.

Traditional and modern uses include support for:

• Air purification and household cleaning (adds antimicrobial boost and fresh scent)
• Mild relief of nasal congestion and improved breathing comfort when inhaled
• Skin care for oily or blemish-prone skin when diluted properly
• Natural pest deterrence for small insects like moths and silverfish

These uses are supported mainly by in vitro (lab) studies and traditional practice. Clinical trial evidence in humans is limited, so claims should be framed carefully.

How to Use Lemon Myrtle Essential Oil

Avoid using undiluted oil directly on large areas of skin. Use the methods below for safe, effective application.

• Diffusion: Add 3-6 drops to a diffuser to freshen a room and support a calming atmosphere.
• Topical dilution: Mix 1-2 drops of lemon myrtle oil with 1 teaspoon (5 ml) of carrier oil for small patch tests. For general topical use, a 1% dilution (about 6 drops per 30 ml carrier oil) is commonly recommended.
• Room spray: Combine 10-15 drops with 100 ml water and a splash of witch hazel in a spray bottle. Shake before use.
• In cleaning: Add 10-20 drops to homemade cleaning solutions (vinegar or soap-based) to boost antimicrobial properties and add scent.
• Pest deterrent: Place a few drops on cotton balls in pantry corners or wardrobes to deter small insects.

Safety Precautions

Lemon myrtle is generally safe when used responsibly, but it is powerful and can cause irritation or allergic reactions in some people.

• Always perform a patch test before wider skin use: apply a small diluted amount to the forearm and wait 24 hours for a reaction.
• Do not apply undiluted (neat) to the skin. Dilute with a neutral carrier oil such as jojoba, sweet almond, or fractionated coconut oil.
• Avoid use on broken or inflamed skin unless advised by a healthcare professional.
• Avoid internal ingestion unless under the supervision of a qualified practitioner. Internal use carries risks and is not necessary for most benefits.
• Children, pregnant or breastfeeding people, and people with severe asthma or epilepsy should consult a healthcare provider before using essential oils. Inhalation can trigger respiratory symptoms in sensitive individuals.

Practical Tips and Storage

Store lemon myrtle oil in a cool, dark place in a tightly sealed amber or cobalt bottle to preserve its quality. Keep out of reach of children and pets.

Because citral can oxidize over time, check the scent periodically. If the aroma turns sharp or off, discard the bottle.

When blending with other oils, lemon myrtle pairs well with:

• Tea tree (for added antimicrobial support)
• Lavender (for calming blends)
• Grapefruit or sweet orange (for bright, citrusy blends)

Summary

Lemon myrtle essential oil offers a potent, citrusy option for cleaning, aromatic support, and targeted topical uses when diluted. Laboratory studies support its antimicrobial and antifungal properties, and aromatherapy research suggests mood benefits for some people.

Use it sparingly, dilute properly, and follow safety guidelines, especially for children, pregnant people, and those with respiratory conditions. Stored and used correctly, lemon myrtle can be a useful natural tool in a home wellness kit.
