Origin, Botanical Description, and Traditional Uses

Lemon myrtle (Backhousia citriodora) grows wild in the subtropical rainforests of Queensland, Australia. It’s a tall tree—can get up to 20 meters—with shiny, aromatic leaves. Those leaves are the star of the show, packed with citral.

These days, lemon myrtle is still prized for its scent and supposed wellness uses. It’s not just an Aussie thing anymore—plenty of folks around the world are tossing it in recipes or reaching for it during cold season.

Active Compounds and Therapeutic Properties

Lemon myrtle tea is made by steeping the leaves—dried or fresh—in hot water. It’s got a bright, lemony flavor and a decent dose of vitamin C and antioxidants, which might help out your immune system or offer some relief in winter.

As a culinary herb, lemon myrtle brings a punchy lemon taste to food, but without that sour citrus bite. It’s nice in spice blends, desserts, sauces, marinades—you name it. The dried leaves keep well and are easy to toss into recipes.

Lemon Myrtle for Cold and Flu Relief: Examining the Evidence

Lemon myrtle’s got some interesting compounds that could help fight germs and support your body’s defenses. Researchers are poking around to see how this might play out for annoying symptoms like cough, sore throat, and fever.

Antibacterial, Antiviral, and Antimicrobial Effects

That high citral content? It’s a heavy hitter for antimicrobial action. In lab tests, lemon myrtle oil has been shown to wipe out or slow down bacteria and some viruses. This might be handy for trying to prevent or maybe even shorten a cold or flu.

Because it’s got broad-spectrum action, it can go after a bunch of different germs—helpful during sniffle season. For example, you’ll see lemon myrtle oil’s antimicrobial effects mentioned for cleaning and personal use. But let’s be real: most of these results are from lab dishes, not people. There’s not much solid proof it zaps flu viruses in actual humans.

Impact on Cough, Sore Throat, and Respiratory Problems

Lemon myrtle might help with coughs and sore throats, thanks to its anti-inflammatory and soothing qualities. A few small studies and plenty of anecdotal stories suggest that breathing in the oil or sipping the tea can make your throat and chest feel a bit better.

This is probably a mix of its germ-fighting and calming effects, which can take the edge off irritated tissues. There are clinical trials in kids with skin issues that saw less inflammation after using lemon myrtle, but honestly, there’s not a ton of research on direct relief for coughs and sore throats from colds or flu.

Role in Supporting the Immune System

Lemon myrtle brings antioxidants and vitamin C to the table, both of which are good for your immune system. These are handy when you’re sick, since your body’s working overtime to fight off germs.

Some folks say the high citral content is especially useful during winter, when bugs are everywhere. Lemon myrtle tea gets hyped for immune support, but—truthfully—there’s not much clinical evidence showing it makes a big difference for healthy people.

Potential Benefits for Fever and Headaches

Thanks to its anti-inflammatory side, some people try lemon myrtle for mild fever and headaches that come with colds or flu. The antioxidants might help dial down inflammation, which can cause aches and headaches.

Still, there aren’t any big studies proving lemon myrtle actually lowers fevers in people. The scent and calming vibe might make you feel a little better, though. Like any natural remedy, it’s best as a supportive option—not a replacement for real medical treatment.

Comparing Lemon Myrtle With Other Natural Remedies

Lemon myrtle gets a lot of love for its antibacterial and antiviral punch. But it’s not the only player—other natural remedies offer their own ways to tackle cold and flu symptoms, and everyone’s got their favorites.

Eucalyptus, Sage, and Ginger

Eucalyptus oil is a classic for steam inhalation—it can help clear your nose when you’re stuffed up. The compounds in it might open up your airways and make breathing less of a struggle. Some people also swear by eucalyptus for coughs because of its cooling feel.

Sage has a long history as a go-to for soothing sore throats. Gargling with sage tea can calm inflammation and knock out some germs. You can also drink it to help with congestion.

Ginger is the one people reach for when they want to warm up or settle their stomachs. It’s great in tea, especially if you’re feeling nauseous or achy from a cold or flu.

Blends With Essential Oils and Aromatherapy

Lemon myrtle oil often ends up in essential oil blends. The citrus scent is super fresh, and people like it for its antimicrobial kick. It’s common to add it to a diffuser to freshen up the air and maybe help with breathing.

Aromatherapy blends sometimes combine lemon myrtle with eucalyptus or tea tree oils, hoping to cut down on congestion and give you a little boost when you breathe it in.

Just a heads up: essential oils need to be used with care. Most should be diluted before touching your skin, and you don’t want to breathe them in for too long. Pregnant women and kids, in particular, should be extra careful with these oils.

Vitamin C, Garlic, and Herbal Supplements

Vitamin C is the old standby for immune support. There’s some evidence it can slightly cut down how long a cold lasts if you start early. Eating citrus or herbal teas is a simple way to get more vitamin C.

Garlic’s another popular home remedy with both antibacterial and antiviral chops. People eat it raw, cooked, or as a supplement to help their immune system, especially for respiratory stuff. It’s been around forever for good reason.

You’ll also hear about herbal supplements like astragalus, which is a staple in traditional Chinese medicine. Research is still ongoing, but some folks believe these kinds of herbs can help keep you from getting sick in the first place.

Safety, Usage, and Practical Considerations

Lemon myrtle gets a lot of attention for cold and flu relief, but it’s worth knowing how to use it safely. Preparation, possible side effects, and how to actually bring it into your daily routine—those are the things that really matter.

Recommended Dosages and Methods of Use

Most folks in the know say lemon myrtle essential oil is generally safe if you keep the concentration low, which is especially true for aromatherapy or anything you put on your skin. For topical use, you’re looking at about a 1% dilution—so, one drop of oil to a teaspoon of carrier oil (almond or jojoba are both good picks). That helps keep irritation at bay.

People often use lemon myrtle in diffusers or vaporizers, and it’s popular for steam inhalation when you’re stuffed up. It’s not a miracle, but a few drops in hot water for steam, or in a diffuser, can feel comforting when your nose is blocked.

You’ll also spot lemon myrtle in things like candles, teas, and cough drops. Stick with the amounts the manufacturer suggests—those products usually use dried leaves or super-diluted oils, which are a lot gentler than the straight essential oil.

Potential Side Effects and Contraindications

The biggest issue with lemon myrtle oil is skin irritation, especially if you skip the dilution. Undiluted oil can definitely cause redness or itchiness, and for anyone with sensitive or already irritated skin, it’s even riskier.

Children under 2 years old really shouldn’t use lemon myrtle oil at all, since their skin can react pretty strongly. There’s no real evidence it causes problems with sunlight, but it’s smart to do a patch test first. And, obviously, keep it away from your eyes, open cuts, or anywhere super sensitive.

If you’re pregnant, breastfeeding, or dealing with ongoing health issues, it’s best to check with your doctor before trying lemon myrtle. If you notice any discomfort or a rash, just stop using it and reach out to a healthcare professional.

Application in Home Remedies and Everyday Wellness

Lemon myrtle pops up a lot in DIY remedies for coughs and sinus congestion. Steam inhalation—adding a drop or two to hot water and breathing in the vapors—is a go-to for many. It’s not a cure, but sometimes you just want something that brings quick relief when you’re under the weather.

Diffusers and vaporizers are an easy way to fill a space with lemon myrtle’s fresh scent, which some find soothing when they’re sick. Candles with lemon myrtle can freshen up the air and maybe make you feel a bit better, at least for a while. Some folks mix diluted oil into homemade balms, but steer clear of using it on broken or irritated skin.

Hair and scalp treatments? Be careful—undiluted oil can be harsh. Always check if the product is safe for skin, and if you’re unsure, do a patch test. Moderation is key, really. If you want to dig deeper into safety, sites like Drugs.com and Down Under Enterprises have more info.
