Herbal Essential Oils: What Are They, Anyway?
Let’s start with the basics, shall we? Herbal essential oils are concentrated plant extracts made from all-natural herbs, right? Unlike a lot of store-bought skincare or wellness products loaded with weird synthetic stuff, these oils are basically nature’s little power packets. And get this—for the most part, they have almost zero bad side effects when you use them properly. Seriously, who doesn’t love a natural fix that actually works? From boosting your mood to clearing up your skin, these oils do so much more than just smell nice. Stick around, and I’ll walk you through all the key benefits, which oils are best for what, and exactly how to use them without messing up.
Top Herbal Essential Oils and Their Unique Benefits
There are dozens of herbal essential oils out there, but these 10 are the most popular, most well-researched, and easiest to find. I’ll break down exactly what each one is good for, plus easy ways to use them so you can start incorporating them into your routine today.
Tea Tree Oil
Tea tree oil comes from the Australian melaleuca alternifolia plant, and it’s a total workhorse for skin issues. It’s one of the few oils that you can use topically straight up (though some people still prefer to dilute it, just to be safe). The big win here? It fights fungi and blemishes like nobody’s business.
- Dab a tiny bit with a cotton swab on acne spots to clear up breakouts fast
- Rub a diluted drop on athlete’s foot or other fungal skin infections for quick relief
- It’s also a staple in tons of over-the-counter skincare products, so you’ve probably used it before without even realizing it!
Lavender Oil
If you ask any essential oil enthusiast, they’ll tell you lavender is the most versatile oil out there. Period. Celebrity dermatologist Dr. Oz even says its scent can lower the levels of stress hormones in your blood—how cool is that? My go-to trick is dropping a few drops in my bath before bed, or rubbing a tiny bit on my wrists and inhaling when I’m feeling overwhelmed before a big meeting.
- It’s perfect for calming irritated skin, minor cuts, and bug bites
- Add a drop to your pillow spray before bed to help you fall asleep faster
- Skincare lovers swear by it for reducing redness and balancing oily skin
Calendula Oil
You know those bright orange marigold flowers you see in garden beds? That’s calendula, and its essential oil is amazing for sensitive skin. It’s so gentle, even people with easily irritated skin can use it without worrying about breakouts.
- It helps fade the appearance of old acne scars over time
- Add a drop to your bath water to soothe psoriasis flare-ups
- It’s also great as a natural moisturizer for dry, chapped hands or lips
Chamomile Oil
Chances are you’ve had chamomile tea before to wind down at night, right? Well, the essential oil has all the same calming, relaxing properties—plus a little extra oomph. I keep a small bottle by my nightstand for those nights I just can’t shut my brain off.
- Rub a diluted drop on your temples to ease tension headaches
- Spray a little on your pillowcase to help you sleep deeper
- It’s also super gentle on sensitive eyes, so you can add a drop to a warm compress for puffy eyes
Peppermint Oil
Okay, peppermint oil is my secret weapon for when I’m dragging at work or feeling bloated after a big lunch. According to certified aromatherapist Scarponi, it “cleanses and stimulates the brain, and boosts mental sharpness.” A 2019 study from the University of Cincinnati even found that inhaling peppermint oil improved thinking accuracy by 28%—whoa.
- Add a drop to a glass of water to ease indigestion and gas (pro tip: don’t drink it straight undiluted, it’s strong!)
- Rub a diluted drop on your temples to clear up sinus pressure or morning headaches
- It’s one of the only essential oils that’s safe to ingest in small doses, so it’s perfect for flavoring homemade smoothies or salad dressings too
Frankincense Oil
Frankincense has been used for thousands of years, and it’s still a fan favorite in holistic wellness circles. Nina Nelson from the blog Shalom Mama calls it a “household staple” for her family. She uses it in her nightly bath to relax, and on minor cuts and bug bites to help them heal faster.
- Scarponi says it can help fight depression, reduce inflammation, boost your immune system, and even improve mental awareness
- Add a few drops to your diffuser during a work session to stay focused and calm
- Dilute it with a carrier oil and rub it on sore muscles to ease tension
Oregano Oil
If you’ve ever heard people raving about oregano oil during flu season, this is why. It has super strong natural antibacterial properties, so lots of people swear by it to fight off colds and other illnesses. Just a heads up: it tastes terrible, so be prepared for that.
- Place 1-2 drops under your tongue daily during cold and flu season to boost your immune system
- It can also be diluted and applied topically to fight skin infections
- Just make sure you don’t take it internally if you’re pregnant or have a chronic condition—always check with a doctor first!
Lemon Oil
Lemon oil is such a bright, cheerful scent—perfect for those days you need a quick pick-me-up. Scarponi says it not only helps detox your body, but it also clears up acne too. Plus, it’s great for boosting focus and concentration, which is why I keep a travel-sized bottle at my desk.
- Mix a drop with water and a little honey for a refreshing, vitamin C-packed drink
- Add a few drops to your homemade cleaning spray to cut through grease and make your home smell amazing
- Pro hack: spray a diluted solution on your pet’s bedding to keep fleas away naturally!
Grapefruit Oil
Another citrusy superstar, grapefruit oil has a lot of the same benefits as lemon oil, but with a slightly sweeter scent. It’s perfect for when you’re feeling tired or jet-lagged after a long trip.
- Add a few drops to your diffuser in the morning to wake yourself up without feeling jittery
- It’s a natural preservative, so you can add it to homemade household cleaners to keep your space safe and clean
- Some people say it helps reduce bloating and support healthy digestion too
Eucalyptus Oil
If you’re stuffed up from a cold or allergies, eucalyptus oil is a game-changer. It’s great for clearing up sinus congestion and easing muscle pain, plus it has antibacterial properties that help boost your immune system.
- Add a few drops to a diffuser while you sleep to breathe easier at night
- Dilute it with a carrier oil and rub it on your chest or sore muscles for relief
- Important note: never ingest eucalyptus oil, and never apply it undiluted to your skin—it can cause serious irritation! Always mix it with a carrier oil like jojoba or coconut oil first.
How to Safely Use Herbal Essential Oils: A Complete Guide
Now that you know all the amazing benefits of these oils, let’s talk about how to use them the right way. There are three main ways to use essential oils, and each one has its own rules and best practices. Let’s break them down one by one.
Aromatherapy: The Most Popular Way to Use Oils
This is the method most people are familiar with—you just inhale the scent directly, or use a diffuser to spread it through your home. It’s great for boosting mood, reducing stress, and clearing up congestion.
- Use a diffuser: add 3-5 drops of oil to a bowl of hot water, or use an electronic diffuser that runs quietly while you sleep, work, or relax. Most diffusers double as humidifiers too, so it’s a win-win for dry winter air!
- Direct inhalation: just take the cap off your oil bottle and inhale deeply a few times, or rub a drop on your wrists and cup your hands over your nose to breathe in the scent.
- Steam inhalation: add a few drops to a bowl of boiling water, lean over the bowl with a towel over your head, and breathe in the steam for 5-10 minutes to clear up sinus congestion.
Pro tip: don’t use the same diffuser for multiple oils without cleaning it first, or you’ll end up with a weird mixed scent that’s not great for anyone!
Topical Application: For Skin and Muscle Issues
Most essential oils are super concentrated, so you can’t just slap them straight onto your skin—they’ll cause irritation, especially if you have sensitive skin. That’s where carrier oils come in! Carrier oils like jojoba, coconut, or sweet almond oil dilute the essential oil so it’s safe to use on your skin.
- The general rule is 2-3 drops of essential oil per teaspoon of carrier oil for most adults. For kids or people with extra sensitive skin, use even less.
- Apply the diluted oil directly to the affected area, like acne spots, sore muscles, or bug bites.
- Never use undiluted essential oil on your face, especially around your eyes or genitals—tea tree oil is one of the only oils that’s safe to use straight up, and even then, some people still get irritated!
Internal Use: Only For Certain Oils
Wait, you can drink essential oils? Well, not all of them. Only a handful of oils are safe to ingest in small doses, like peppermint, lemon, and grapefruit oil. Even then, you have to be super careful not to use too much.
- Add 1-2 drops of peppermint oil to a glass of water to ease indigestion and gas.
- Add a drop of lemon oil to your water or salad dressing for a flavorful, vitamin C boost.
- Always check with a doctor before ingesting any essential oil, especially if you’re pregnant, breastfeeding, or taking medication. Some oils can interact with prescription drugs!
