If you’ve ever walked through a garden full of fresh lemongrass, you know that bright, zesty, almost citrusy scent that hits you right in the face—yeah, that’s exactly what lemongrass essential oil smells like. It’s one of the most popular essential oils out there, and for good reason! I’ve been using it in my diffuser for years to keep my apartment smelling fresh, but lately I’ve been digging into all the other ways it can help with health, skin, and even bug repellent. Let’s break down everything you need to know about lemongrass essential oil, from its actual proven benefits to how to use it safely, plus the little side effects you should watch out for.
What Exactly Is Lemongrass Essential Oil?
First things first: let’s clear up the basics. Lemongrass essential oil is made by steam-distilling the tall, thin leaves of the lemongrass plant, which is actually a type of tropical grass native to South Asia and parts of Africa. You’ve probably tasted it before in Thai or Vietnamese curries, but the oil itself is a concentrated version of that bright lemon flavor and scent.
It’s super common in aromatherapy, skincare products, and even natural cleaning sprays, and honestly? It’s way more versatile than most people realize. Let’s dive into all the science-backed (and some just super popular) benefits it has to offer.
Lemongrass Essential Oil Benefits and Uses
1. Natural Bug Repellent (The OG Use!)
Okay, let’s start with the big one—everyone knows lemongrass oil keeps bugs away. Seriously, this is the most well-documented use of the oil, and for good reason. The CDC even mentions lemongrass oil as an effective insect repellent, especially against mosquitoes. If you’ve ever slathered on a chemical bug spray and hated the sticky residue, this is your perfect alternative.
You can mix a few drops with a carrier oil like coconut oil and rub it onto your skin before heading outside, or add a few drops to a candle or diffuser to keep mosquitoes away from your patio. I keep a small travel bottle of diluted lemongrass oil in my beach bag every summer, and it’s saved me from so many itchy mosquito bites!
2. Fights Harmful Gut Parasites and Aids Digestion
One of the lesser-known but super impressive benefits of lemongrass oil is that it can help get rid of unwanted parasites in your digestive tract, like worms. Studies have shown that the active compounds in lemongrass oil can inhibit the growth of these harmful bugs, which in turn can help boost your appetite and ease digestive discomfort.
It’s also great for overall gut health: it has anti-inflammatory properties that can soothe irritation in your stomach, intestines, and digestive tract. If you’ve been dealing with bloating or an upset stomach, a quick aromatherapy session with lemongrass oil, or a tiny diluted drop mixed into a glass of water (only under professional supervision, more on that later!) might help you feel way better.
3. Natural Detox and Diuretic Properties
Lemongrass oil acts as a diuretic, which means it helps your body produce more urine. That might sound weird, but it’s actually a good thing! More urination helps flush out excess water weight, salt, and toxins from your body, which can help keep your kidneys healthy and reduce bloating.
It also has sweat-inducing properties, which help your body get rid of excess fat, oil, and even uric acid through your skin. All of this together makes it a great addition to your post-workout routine or if you’re looking to give your body a gentle natural detox.
4. Eases Joint and Muscle Pain
If you’ve got sore muscles after a gym session or achy joints from sitting at your desk all day, lemongrass oil is a game-changer. It’s a powerful pain reliever and anti-inflammatory, which means it can calm down swelling and dull that sharp ache fast.
Here’s how to use it: mix 3-4 drops of lemongrass oil with a carrier oil like sweet almond or jojoba oil, then massage the mixture directly onto your sore muscles or joints. I like to do this right before bed after a long run, and it helps me wake up feeling way less stiff. Just make sure you don’t use undiluted oil on your skin—more on that safety stuff later!
5. Boosts Mood and Fights Depression and Fatigue
That bright, citrusy scent isn’t just nice to smell—it actually has mental health benefits too. Lemongrass oil is a natural antidepressant and mood lifter. Inhaling it can help calm feelings of stress, anxiety, and even mild depression, and it can cut through that brain fog you get after a long day at work.
I keep a mini diffuser on my desk at home, and when I’m feeling burnt out from scrolling through emails or studying, I add a few drops of lemongrass oil and just take 5 minutes to breathe it in. It’s like a quick pick-me-up that doesn’t require any coffee (though don’t get me wrong, I still love my morning latte!).
6. Improves Skin Health
You’ll find lemongrass oil in tons of skincare products, and for good reason. Its antibacterial and antifungal properties make it perfect for treating and preventing skin infections like acne, warts, and boils. It also helps reduce excess oil on your skin, which is great if you have oily or combination skin that gets greasy throughout the day.
Plus, it can help even out your skin tone and tighten your pores, which makes your skin look smoother and more youthful. You can add a drop or two to your regular face wash or moisturizer, or mix it with a carrier oil for a quick face mask. Just make sure you do a patch test first—some people can be sensitive to it!
Since it helps detox your body from the inside out, it can also give your skin a healthy, glowing finish. No more dull, tired-looking skin—hello, radiant complexion!
7. Fights Infections and Helps Wounds Heal Faster
Thanks to its strong antimicrobial properties, lemongrass oil can help prevent infections in cuts, scrapes, and other small wounds. If you get a small cut while cooking or gardening, dilute a drop of lemongrass oil with a carrier oil and dab it onto the wound—it’ll help keep bacteria away and speed up the healing process.
It also helps reduce redness and swelling around the wound, so you won’t have to deal with as much irritation as you would if you left it untreated.
8. Neutralizes Odors and Freshens Up Your Space
Let’s be real: most commercial air fresheners are full of weird chemicals that smell fake as heck. Lemongrass oil is a natural, fresh-smelling alternative that can get rid of stubborn odors instead of just covering them up. You can add a few drops to a diffuser, mix it with water and vinegar for a natural cleaning spray, or even add a drop to your laundry to keep your clothes smelling fresh.
I use a lemongrass cleaning spray on my kitchen counters every week, and it gets rid of all the food odors and leaves my place smelling like a sunny tropical garden. Way better than that overpowering lemon-scented spray from the grocery store!
How to Safely Use Lemongrass Essential Oil
Now, before you go dumping undiluted lemongrass oil all over your skin or chugging a drop straight from the bottle, let’s talk about safe usage. Essential oils are super concentrated, so they need to be handled carefully. Here’s everything you need to know:
1. Never Use Undiluted Oil on Your Skin
This is the number one rule for all essential oils, and lemongrass is no exception. Undiluted lemongrass oil can cause skin irritation, redness, and even chemical burns. Always mix it with a carrier oil like sweet almond oil, jojoba oil, or coconut oil before applying it to your skin. A good ratio is about 2-3 drops of essential oil per teaspoon of carrier oil.
2. Do a Patch Test First
If you have sensitive skin or have never used lemongrass oil before, do a patch test to make sure you don’t have an allergic reaction. Mix a tiny drop of diluted oil onto the inside of your elbow, cover it with a bandage, and wait 24 hours. If you see any redness, itching, or swelling, don’t use the oil on your skin.
3. Avoid Sun Exposure After Using It Topically
One lesser-known side effect of lemongrass oil is that it can make your skin more sensitive to the sun. This is because of a compound called citral, which is found in the oil. If you apply diluted lemongrass oil to your skin, try to stay out of direct sunlight for a few hours, or wear sunscreen to avoid getting sunburned.
4. Use It Safely in Aromatherapy
Aromatherapy is one of the safest ways to use lemongrass oil. You can add 3-5 drops to a diffuser, put a few drops on a cotton ball and leave it in your room, or even add it to a warm bath. Just don’t inhale it directly from the bottle—this can irritate your nasal passages!
For a relaxing bath, add 3-4 drops of diluted lemongrass oil to your running warm water. It’s the perfect way to unwind after a long day.
5. Never Ingest Lemongrass Oil Without Professional Supervision
This is a big one. Even though some people swear by ingesting small amounts of essential oils, the American Holistic Aromatherapy Association says that internal use of essential oils is generally not recommended, and you should never do it without consulting a licensed healthcare provider first.
If you accidentally ingest a small amount, don’t panic, but call your doctor right away. Ingesting undiluted lemongrass oil can cause stomach pain, throat irritation, and even coughing.
6. Keep It Away From Your Eyes
If you get lemongrass oil in your eyes, rinse them out immediately with cool water. It can cause redness, irritation, and temporary clouding of the cornea, but this usually goes away on its own within a week. If the irritation doesn’t go away after a few days, see a doctor.
Lemongrass Essential Oil Side Effects and Precautions
For most people, using lemongrass oil properly is safe, but there are a few side effects and precautions you should be aware of:
- Skin irritation: As we mentioned earlier, undiluted oil can cause redness, itching, and swelling. Always dilute it before using it on your skin.
- Allergic reactions: While rare, some people can have an allergic reaction to lemongrass oil. Symptoms include hives, difficulty breathing, and swelling of the face, lips, or tongue. If you have any of these symptoms, seek medical help immediately.
- Increased sun sensitivity: As we talked about earlier, lemongrass oil can make your skin more prone to sunburn. Avoid direct sunlight after using it topically.
- Heart rate changes: In some cases, undiluted lemongrass oil applied to the skin can cause tachycardia, or a faster than normal heart rate. This is another reason to always dilute your oil!
- Toxicity if ingested: As we mentioned, ingesting lemongrass oil can cause stomach pain, throat irritation, and other digestive issues. Never ingest it without professional guidance.
Also, if you’re pregnant, breastfeeding, or taking any medications, talk to your doctor before using lemongrass oil. There’s not a lot of research on how it affects pregnant or breastfeeding people, so it’s better to be safe than sorry.
Final Thoughts on Lemongrass Essential Oil
At the end of the day, lemongrass essential oil is a versatile, affordable, and natural product that can help with so many different things—from keeping bugs away to easing your sore muscles to making your home smell amazing. Just remember to use it safely, dilute it properly, and do a patch test if you’re new to it.
I’ve been using lemongrass oil for years, and it’s become a staple in my self-care routine. Whether I’m diffusing it in my bedroom at night to help me sleep better, or mixing it with coconut oil to massage my sore shoulders after a workout, it never fails to make me feel better. If you haven’t tried it yet, I highly recommend picking up a bottle—you won’t regret it!
