Essential Oils for Rosacea — My Story & What’s Helped

Essential Oils for Rosacea: My Experience & What's Helped #aromatherapy #essentialoils #rosacea #skincare

I’m so excited to share this blog post series with you! Rosacea is something I was personally struggling with prior to beginning my aromatherapy certification course, so when it came time to do case studies as part of my graduation requirements, I knew I wanted to dive deep into the issue. Over the next few days, I’m going to share everything I’ve learned about aromatherapy and essential oils for rosacea with you. I’ll also share the exact blends I’ve been using and show you how to make your own at home.

My skin has improved a ton, which is why I’m so pumped to share this all with you. That being said, we’re all different and what works for me may not work for you. I’m a Certified Aromatherapist—not a dermatologist or a doctor—so while I 100% stand behind aromatherapy as a complementary therapy, the advice I share here shouldn’t replace that of a medical professional.

What Is Rosacea?

The following is taken from the rosacea case study and intervention guidelines from my aromatherapy course. I’ve edited it a little to be more conversational. Sources are sited at the bottom of this blog post.

Rosacea is a chronic inflammatory skin disease characterized by flushing, fibrosis, redness, broken capillaries and dryness. Skin affected by rosacea can be couperose with the additional presence of acne-like papules. “Couperose” is redness due to the presence of dilated red blood vessels, so you get the appearance of tiny red spider-like veins on the surface of the skin. This can be accompanied by an irritating, tight, tingling, burning feeling. Rosacea typically affects the cheeks and nose but can affect other areas of the face as well.

There are four major subtypes of rosacea:

  • Erythematotelangiectatic rosacea
  • Papulopustular rosacea
  • Phymatous rosacea
  • Ocular rosacea

Rosacea is primarily caused by poor elasticity in capillary walls. When body temperature increases or blood rushes to the face, capillary walls expand. If they aren’t sufficiently elastic, they won’t, however, properly contract again to their original shape or size. This results in distended capillary that hold blood cells and give the appearance of redness on the face. This skin condition is aggravated by digestive disorders, poor nutrition and nervous disorders (Battaglia).

Rosacea involves several different regulatory systems (immune, nervous, vascular) and often affects multiple family members, suggesting a genetic component as well. Rosacea is most prevalent among middle-aged women, with the onset occurring most often between ages 30-60 or after menopause. It’s common in people with delicate, thin skin where the weakening capillary walls to the blood vessels in the face become easily visible (Steinhoff).

Factors that can trigger or exacerbate rosacea symptoms:

  • Sun exposure
  • Extreme hot/cold weather or rapid change in temperature
  • Stress
  • Consumption of spicy foods
  • Intense exercise
  • Alcohol
  • Tobacco

My Experience with Rosacea

If you don’t care about my personal experience with rosacea and just want to find out more about helping your own situation, I totally understand and suggest you scroll passed this section. 😉

A couple years ago, I had what I thought was an allergic reaction to wine. My cheeks weren’t just flushed—they were bright red and felt tight, tingly and itchy. The next morning, they were better but I was left with tiny red marks that looked a bit like zits. I brushed off the incident, thinking I’d just stop drinking that brand of wine.

But then this redness issue started happening more frequently, and completely unrelated to drinking wine. If I did an intense workout, took a hot shower, or even was just experiencing anxiety, my face would flare up. And the redness wouldn’t go away. It almost looked like I had a breakout, with tiny splotches that looked like blemishes and others that looked like broken blood vessels. This got worse and more frequent over the year.

Even when I wasn’t having a flare-up, you could see the spots and small red blotches, almost like healing acne scars:

Essential Oils for Rosacea: My Experience & What's Helped #aromatherapy #essentialoils #rosacea #skincare

I’ve never had sensitive skin until now. It’s super oily, so while I struggled with breakouts in high school and college, I never had issues with redness, irritation or sensitivity. Because of this, I kinda just assumed the issue would correct itself. But I was getting increasingly self-conscious about my complexion. To make matters worse, these flare-ups (which were often triggered by anxiety), would make me feel even more anxious and insecure, so the redness would just get worse and deeper. Finally this motivated me to do some research.

All signs pointed to rosacea. (Two estethitians and an RN also agreed with my self-diagnosis, so this isn’t coming from Dr. Google.)

If I were to re-list all the rosacea symptoms and triggers I outlined in the previous section of this post, it’d be like check, check, yup, yes, got that, that’s me, shit—check.

It also makes sense to me because rosacea is caused by poor elasticity of the capillary walls, and when it comes to the circulatory system in general, I’ve always had minor issues. Nothing serious (so grateful for my general good health!), but I have Raynaud’s, which is a narrowing of the small arteries that reduces blood flow to the extremities. It’s triggered by cold temperatures and sometimes stress. Also, every time I’ve had to get blood drawn by a doctor, they always have difficulty and joke with me how tiny my veins are. I have many talents, but circulating blood efficiently throughout my body is apparently just not one of them.

This is a little aside, but pertinent: A while back, I wrote about my decision to stop drinking coffee. At the time I wrote that post, I didn’t have the full picture of what effect caffeine was having on my body. But in the years since quitting, I have now noticed that my threshold for what triggers a Raynaud’s episode seems a lot higher. I don’t seem to be as sensitive to the cold. I had already stopped drinking coffee when the onset of my rosacea began, but I have a strong feeling it would make it worse if I were to start drinking it again. Just wanted to highlight for anyone dealing with Raynaud’s and/or rosacea: Try ditching the caffeine (and/or other stimulants you might be taking). It’s been a game-changer for me.

I was knee-deep in my aromatherapy course when I realized I most likely had rosacea, so the first steps I made in treating it were to research, research, research and develop essential oil blends. I made a facial oil, a toner and a cooling misting spray, all of which I use regularly or daily. More on those below!

As with anything, the most effective treatment is one that takes into consideration not just the symptoms, but the cause. Essential oils are great and I absolutely love my skin care routine, but that’ll only get you so far. There are lifestyle changes, dietary considerations and other holistic interventions that are important, too. I’ll go into these in detail below, but the big things for me have been avoiding extreme temperature and caffeine, and managing anxiety.

I still have some redness issues with my skin and am working to improve that and my overall complexion, but in general—SO MUCH BETTER. The rosacea before-and-after pics in this post speak for themselves. That being said, before-and-after shots can be a bit misleading, and while I took these pictures in the same area of my apartment in front of the window, clearly there was better lighting the day I took the “after” shots. Still, the improvement is drastic, even without the help of good lighting!

Really the only time I feel like I have a rosacea flare-up is when I experience nervous anxiety. It’s usually in a good way—like before public speaking or in anticipation of something really exciting. The thing with these flare-ups is they don’t just go away when the anxiety subsides. They leave redness, irritation, and a rash-like appearance across my cheeks for hours, days or even weeks. My essential oil routine definitely helps with the duration and intensity, but my next step will be to look into how I can use aromatherapy to help calm this nervous anxiety to nip the situation in the bud. I’ll of course keep you all posted!

Essential Oils for Rosacea: My Experience & What's Helped #aromatherapy #essentialoils #rosacea #skincare

Main takeaways from my experience:

  • Your skin changes as you get older. What worked for you in your 20s might not work for you in your 30s/40s/etc.
  • Extremes don’t work well (for me). Extreme heat (or cold for my Raynaud’s), extremely intense workouts, extreme stress/anxiety, extremely spicy foods, extreme caffeination—no bueno. Finding balance and moderation makes for calm skin.
  • Simple skincare is best (for me). Everyone is different, but I’d encourage people with any sort of skin sensitivity or redness to simplify their skincare routine. Minimal, thoughtfully-selected ingredients have made my skin the happiest.
  • Lasting change takes time—be patient! This is important to keep in mind as you read the rest of this blog post where I share specific aromatic blends for rosacea. Real improvement in my skin took close to a *year*. For reference, the “before” pics are from April 2018 and the “afters” are from February 2019. I noticed reduction in severity of flare-ups pretty quickly, but for real change I had to be patient and stick with it.

Essential Oils for Rosacea — How Aromatherapy Can Help

Essential Oils for Rosacea: My Experience & What's Helped #aromatherapy #essentialoils #rosacea #skincare

I’m going to start general and then get specific with recommendations and the blend recipes that I personally use.

Essential Oils for Rosacea

Links in this section are mostly to Plant Therapy, a brand I personally use and love. For other brands I’d recommend, check out this post. Below links are affiliate.

If you’re looking at the below list thinking it seems long, that’s because everyone’s skin is different. It’s important to list all the options for rosacea so that you can find a combination of oils that works for you.

In general, what these oils all have in common is that they’re gentle (great for not just rosacea but any sensitive skin!) and have anti-inflammatory properties. If you’re going to make a blend for yourself, I’d highly recommend incorporating one of the first three listed below (German chamomile, Helichrysum and/or Rose otto).

  • German chamomile (via Amazon) – One of the gentlest essential oils, making it great for treating sensitive skin issues. Anti-inflammatory, anti-allergenic and supports calmness.
  • Helichrysum (via Amazon) – Great for sensitive skin and inflammation, broken veins, couperose skin and old scars.
  • Rose otto (via Amazon) – Ideal for skin care, especially sensitive, mature and/or dry skin. Indicated for broken capillaries and poor circulation. This essential oil is pricey. I love it, but if you’re trying to keep the cost of your blend down, I’d use Helichrysum and/or German chamomile instead.
  • Lavender (via Amazon) – Another gentle oil that’s safe for almost all skin types. Good for skin inflammations, and calming for both skin and emotions. You can read more about Lavender essential oil in the linked blog post.
  • Neroli (via Amazon) – Tones the skin and is good for sensitive skin; also a circulatory tonic.
  • Sandalwood (via Amazon) – Relieves itching and inflammation, can be helpful in calming a rosacea flare-up.
  • Carrot seed (via Amazon) – Good for irritated skin. A depurative, which are used in the treatment of chronic inflammatory diseases. Carrot seed is an essential oil but is most often used as part of a carrier. Don’t use undiluted on the skin.
  • Jasmine (via Amazon) – Good for dry and/or sensitive skin. Jasmine is also used to support anxiety, so if your rosacea is triggered by anxiety it can be helpful.

Anti-inflammatory essential oils are beneficial for soothing and reducing the inflamed, flushed skin. A 2018 study applied moisturizer with anti-inflammatory and antioxidant botanicals to just half of 30 subjects’ faces affected by chronic redness. The half treated with these botanicals showed a statistically significant improvement in scaling, flaking, smoothness, firmness and overall appearance of redness (Draelos).

One note: With papulopustular rosacea, sufferers have a higher density of Demodex folliculorum mites on their faces. These bacterium have the potential to stimulate the inflammatory rosacea response (Lacey). If you have this particular type of rosacea, essential oils with antibacterial and antimicrobial properties (as well as anti-inflammatory) are going to be most useful in treatment. From the above list, Lavender and Neroli would be good options (especially Lavender).

Carrier Oils for Rosacea

Carrier oils are the vegetable oils in which you dilute essential oils before applying to your skin.

  • Jojoba (via Amazon) – Good for inflammation and all skin types. Jojoba oil is actually a liquid wax and is similar to the sebum our own body produces, making it ideal for skin care.
  • Tamanu (via Amazon) – Has anti-inflammatory and anti-oxidant properties; used in healing damaged skin and rashes.
  • Apricot kernel (via Amazon) – A fine, light seed oil that helps with healing and rejuvenating skin cells. Used frequently in facial preparations and is great for delicate, inflamed and/or sensitive skin.
  • Borage seed (via Amazon) – High in GLA (gamma linoleic acid), which is an anti-inflammatory and important for healthy skin. Recommended to used in 10% dilution.
  • Hazelnut (via Amazon) – Useful in facial oil blends because it’s easily absorbed and good for all skin types. It’s rich in vitamins, minerals and protein.
  • Avocado (via Amazon) – Great for aging, dry and/or undernourished skin. It’s rich and heavy, and good for all skin types. Short shelf life so store in the refrigerator and buy it in small quantities.
  • Safflower (via Amazon) – Good for all skin types and helps soften the skin. Has a light-medium consistency and is pretty odorless if you’re sensitive to scents.
  • Sesame oil (via Amazon) – A lightweight oil rich in Vitamin E, minerals, protein and lecithin that can speed healing and prevent drying. Not to be confused with the toasted sesame oil you find in the grocery store.

Specific Aromatherapy Blends for Rosacea

This section includes specific aromatherapy blends for rosacea and links out to the exact recipes I personally use.

Daily Facial Oil

Facial Oil for Rosacea: DIY Essential Oil Blend - learn how to make a facial oil for rosacea that's best for YOUR skin. #rosacea #essentialoils #aromatherapy #skincare

For the exact blend recipe I personally use, check out My Facial Oil for Rosacea.

With any type of sensitive, inflamed skin, it’s best to avoid complex blends of essential oils. There may be several oils and carriers on the above lists that sound perfect for you, but try to keep your blends simple. 1-2 carriers, 2-3 essential oils max. Start there and then if you want to try incorporating others into the blend, you can.

Facial oils should be applied to moist skin after cleansing and toning, by putting a couple drops on fingertips and gently smoothing/patting on in an upward motion.

Here’s a general guideline to make a facial oil blend for rosacea. Use the lists above to select essential oils and carriers.

  • 1 oz (= 2 tbsp) carrier oil(s)
  • 12 drops essential oil(s)
  • 400 IU Vitamin E

I recommend adding an antioxidant like Vitamin E to facial oil blends because it’ll prolong the shelf life—plus Vitamin E is great for skin. You can buy a bottle of Vitamin E gels where ever you buy supplements and simply rip open the gel casing and squeeze it out into your blend.

The above recipe guidelines will make 1 oz of facial oil at a 2% dilution. For really sensitive skin, you may want to reduce the number of drops of essential oils further so it’s more like a 1-1.5% dilution. However, the oils recommended are gentle and specifically suited to sensitive skin, so I wouldn’t anticipate problems at 2%.

Add your carriers and antioxidant then the essential oils, and shake to combine. It’s always smart to do a skin patch test of essential oils to make sure you don’t have an allergy or sensitization to them before using in a blend. More on essential oil safety in this post.

Daily Hydrosol (Floral Water) Toner

Essential Oils for Rosacea: My Experience & What's Helped #aromatherapy #essentialoils #rosacea #skincare

The goal of a toner is to balance the skin’s pH and provide moisture. You should apply it daily after cleansing and before a facial oil. Safe, gentle, alcohol-free toners can be hard to find, so it’s best to use a simple floral water and add some apple cider vinegar if you have rosacea or general sensitive, easily-irritated skin. Chamomile, orange blossom and lavender floral water are the most gentle options.

I personally use a German Chamomile hydrosol toner with apple cider vinegar. Read more about it and learn how to make it yourself at home here: DIY Chamomile Floral Water Toner. And if you’re looking for a ready-to-use product, I’d recommend the brand Hello Cider (organic and available via Amazon Prime).

Cooling Mist for Flare-Ups

During a flare-up, when the heat is rushing to the face, a cooling toner or facial mist can be beneficial. Peppermint is a great cooling oil, but should be used in very low dilution with aloe vera and distilled water for a facial mist.

Read all about the blend I use and other options in this post about cooling mists for rosacea flare ups.

Aromatherapy for the Bigger Picture

With holistic aromatherapy, you want to treat the issue and the symptoms, but also take a step back and look at the bigger picture. What’s triggering the symptoms? What emotional distress are the symptoms causing? What other issues are there in the person’s life that may contribute to the symptoms?

If, for example, stress and anxiety are a trigger for your rosacea flare-ups, aromatherapy for these emotional issues could be beneficial. Diffusing an anti-anxiety blend during stressful times could reduce these feelings and therefore prevent a rosacea flare-up.

I can’t speak for everyone with the condition, but I know I was feeling insecure about the appearance of my skin and really down when my rosacea was at its worse. There are essential oils with uplifting, anti-depressant effects that can be beneficial for these emotions as well.

Other Holistic Interventions for Rosacea

Using essential oils for rosacea without making any lifestyle changes to go along with it is like eating a healthy breakfast while continuing to eat processed junk the rest of the day. It helps, and it’s certainly a step in the right direction—but for lasting, significant change, you gotta go deeper.

Lifestyle Changes

Avoid extreme hot or cold temperatures, saunas, sun exposure, smoking, alcohol, caffeine, and intense exercise that causes the face to turn red. Emotional stress can be a trigger as well so prioritize self-care and stress management (yoga, meditation, diffusing an essential oil blend for stress, etc.).

From the above, it’s really just intense exercise, sun exposure and alcohol that I’m guilty of enjoying. I use a cooling mist spray after intense exercise that seems to help, and it’s really only in the summer when I get so overheated from a workout that my rosacea flares up. As for sun exposure, I started wearing a hat at the beach this past summer which helps. I do still drink alcohol but not even weekly—and I find if I stick to beer, my skin is fine.

I also wash my face with cool water now. Living in Boston, there’s just no way in hell I’m taking a cold shower in the winter. So I’ll save the cold face washing for after my shower at the sink. This has seemed to help!

Dietary Changes

Avoid drinking hot liquids and eating spicy foods. Foods that cause inflammation can be a potential trigger, so eliminating dairy, gluten and foods in the nightshade family (whaddup Tom Brady) can be helpful for some.

I don’t eat dairy or enjoy hot liquids, but I love spicy food and eat gluten regularly. I’ve turned down the intensity of the hotness of the spicy food I eat, just to be safe. I don’t have any sensitivities to gluten, and have never noticed an adverse reaction to it. I personally would only try eliminating it if my rosacea came back and stayed around and it was my last resort. That being said, if you have a sensitivity to gluten, it could be exacerbating your rosacea, and it’s worthwhile to look into that possible connection.

Products to Avoid

Products to avoid if you have rosacea are similar to those anyone with sensitive, easily irritated skin should look out for:

  • Harsh scrubs and alcohol-based toners
  • Artificially fragranced soaps, makeup, moisturizers, detergents, etc.
  • Synthetic fragrance or perfume
  • Chemical preservatives
  • Petroleum or lanolin byproduct
  • Coconut, cocoa butter and corn oils can also be sensitizing (Cooksley)

—————————

I know this blog post was long, but I really want it to be as comprehensive as possible. My goal is for it to be your go-to guide to essential oils for rosacea.

Keep in mind that everyone is different, and aromatherapy is most successful when done with the individual in mind. The oils and blends that work amazingly for me may not have the same results for you, for a variety of reasons.

My goal in sharing all this information is to give you a guidelines, upon which you can build. Try different things, ask questions, and be patient as you figure out what works best for you.

And speaking of questions, leave them in the comments below! Sometimes I admittedly slack on responding to blog comments if the post is older, so you can also always send me a DM on Instagram (@nicolepearce)—I’m very responsive there!

EOs 101: Basic Essential Oil Safety

EOs 101: Essential Oil Safety - Al the basics you need to know for using essential oils safely. #aromatherapy #essentialoils https://pumpsandiron.com

Today is the final post of my EOs 101 series before we jump into the fun stuff. We’re talking all things essential oil safety. When I share blend recipes on the blog, I’ll give detailed information about dilution percentages, application frequency and safety precautions for that specific blend, so for today’s post, we’re going to stick to the basic foundational safety information you need to know.

If you’re interested in learning more, Robert Tisserand’s Essential Oil Safety is the holy grail on the topic. That being said, it’s a deep dive into essential oil science, so not exactly a necessary read if you just want to diffuse some oils to make your apartment smell pretty. 😉

Speaking of Tisserand, he has a partnership with the essential oil retailer Plant Therapy. So even if you prefer a different brand of oils, I highly recommend PT’s website as a safety resource. If you have questions regarding a specific oil, find it on Plant Therapy and read up on the safety considerations, suggested usages, and more.

Essential Oil Safety: How & How Much to Use

The two primary ways in which we apply essential oils therapeutically are topically through the skin and inhalation. They can be administered orally when done under the supervision of a medical professional also trained in clinical aromatherapy, but I do not recommend it otherwise. I’ll elaborate later in this post.

There are a couple exceptions, however, that I’ll quickly touch upon here and will elaborate on in future posts. If you’re nauseous, you can put a drop of Peppermint essential oil on a sugar cube and suck on it. Similarly, for sore throat issues, a drop or two of essential oils can be added to a lozenge. Notice I say *a* drop or two. We’re talking small amounts added to a carrier (sugar cube, lozenge) and slowly consumed via sucking. If you’re working with a qualified practitioner who is having you take higher doses via capsule under careful instruction, that’s awesome. But if you’re just experimenting with essential oils at home, stick to other modes of application.

All that being said, don’t panic or anything if you get a drop or two in your mouth—not a big deal unless you have an allergy.

Topical Application

You always want to dilute essential oils before applying to your skin, except when putting on a small area for an acute condition like a burn, infection, bug bite or pimple (a dab of Tea tree oil on zits is my jam!). If you’re applying via hydrotherapy (a bath), it’s safe to just add the essential oils to the water, but it’s more effective if you use a dispersing agent like epsom salt or even milk (otherwise the oils won’t mix as well throughout the water).

You dilute essential oils in carriers, which are typically vegetable, nut, seed, or infused oils (rosehip seed oil, jojoba, sweet almond, olive oil, etc.). The percentage to which you dilute the blend depends on the purpose of the blend and person being treated. I’ll go over those details any time I share a specific blend recipe. But to give you an idea, most essential oil lotions and massage oils are only 1-4% essential oil, with the rest being carrier. If treating an acute condition affecting a small area, that percentage could be more like 10%+. A little goes a long way and more is not more when it comes to efficacy. In fact, sometimes an essential oil can have the opposite of its intended effect when used in too high a concentration.

When applying to your skin, don’t use too close to your eyes. If you do get essential oils in your eyes, wash them out with whole milk or wick away from the eye with a vegetable oil.

Inhalation

While topical applications are typically the best method of administration for physical ailments (sore muscles, infections, skin issues, cramps, etc.), inhalation is best suited for emotional, mental and spiritual purposes. And that being said, there are of course instances like sinus infections and respiratory issues where it’s the ideal application for physical aid as well.

If you’re using a diffuser, the method most of us are familiar with, 8-10 drops of essential oil/s is usually perfect. That will depend on size and amount of water it holds, but works for most standard diffusers that hold around 100mL. You don’t want the scent diffused in the room to be overpowering (remember—more is not more!), so it’s usually best to utilize your diffuser’s intermittent feature if it has one. If your diffuser only dispenses in a steady stream, put it on for 15 minutes at a time, doing so every hour or so.

Use these timings as a general guide—size and ventilation of the room will cause this to vary. And it’s more so about efficacy of the therapy than a safety hazard to diffuse oils for extended periods of time. If you leave your diffuser on while you go to work, for example, you’re by no means coming back to a toxic apartment.

Ingestion

This is a highly debated topic: Should you take essential oils orally? As I mentioned, yes, there is a safe way to ingest them. But no, unless you’re woking with a medical professional and clinical aromatherapist specifically trained in this, you should not.

When taken orally, a significantly higher percentage of the essential oil will reach circulation (vs inhalation or topical application). This means a significantly higher percentage will reach your liver for processing.

Another safety consideration is that many essential oils have strong antibacterial properties. So you can potentially mess up the balance of your good gut bacteria if you’re not taking them properly.

Finally, on the other end of it, stomach acidity and the enzymes in the intestines can destroy the essential oil constituents that make them effective in the first place.

Sensitizations & Allergies

If you’re allergic to a plant or fruit, you’ll most likely be allergic to its essential oil. Especially if you have a history of allergies or skin sensitivities, you should perform a skin patch test before putting an essential oil in a blend. Put a drop of the oil on a cotton ball and swipe it on the inside of your arm by your elbow. In 15-20 minutes check the area (you can put a bandaid over it while you wait). If there’s redness or itching, you have a sensitization or allergy to that oil.

It’s also important to keep in mind that if someone is sensitized to a chemical component in an essential oil, they’re more likely to also have an adverse affect with other essential oils high in that component. Also make sure you’re using quality, pure—organic if possible—essential oils (read this post for more info on identifying these). Sometimes an allergic reaction isn’t to an essential oil but to a chemical or preservative used in growing and/or packaging it.

If you’re using the same oils frequently for an extended period of time, you’ll be more susceptible to developing a sensitization. This is especially true if it’s a concentrated blend being applied to the same area in chronic conditions (for example, a twice-daily arthritis rub for your hands). To avoid this, rotate the oils blends that you’re using.

Pregnancy, Kids, Older Populations

The main thing when creating blends for children, an elderly person or a pregnant woman is to use a lower dilution, especially for topical applications. Typically a 1% dilution instead of the standard 2% dilution you’d use for most body oils and lotions. Inhalation is not age dependent, but you shouldn’t expose kids under two to strong oil odors, so it wouldn’t hurt to use fewer drops.

If pregnant, it’s important to understand that the placenta is a membrane like any other in that essential oils can penetrate it (same goes with lactating mammary glands). So the essential oils you use on your body will also reach your fetus. And during pregnancy, your sense of smell is heightened. So you might find that 8-10 drops in a diffuser is too overpowering. Use fewer to keep the scents subtle.

The following essential oils should be avoided during pregnancy:

  • Aniseed
  • Basil
  • Camphor
  • Clove
  • Cinnamon
  • Hyssop
  • Lemongrass
  • Nutmeg
  • Origanum
  • Savory
  • Tarragon
  • Thyme

The following essential oils should be avoided during the first trimester:

  • Cajupet
  • Caraway
  • Clary sage
  • Fennel
  • Juniper
  • Marjoram
  • Melissa
  • Myrrh
  • Niaouli
  • Patchouli
  • Rosemary

It should be noted that if you have a history of miscarriages, it may be best to avoid all essential oils in your first trimester. Don’t stress if you walk into a room with an essential oil diffuser running by any means, but it may be advised to avoid regular application.

There are lots of oils that are safe and very useful during pregnancy. I’ll do a whole blog post on that eventually!

Pets

You can safety use aromatherapy on dogs and horses is. It not recommended for cats or small animals (birds, gerbils, etc.) because their livers can’t metabolize the chemical constituents in the essential oils.

Now, before all the cat owners freak out—I have seen studies being done regarding certain essential oils safely used with cats. This is not my area of expertise and my training advises against it, but you may want to do your research after finishing this blog post.

With dogs, you want to dilute oils well before application. Here are guidelines by size:

  • Dogs under 25 lbs: 0.25 – 0.5%
  • 25-50 lbs: 0.5 – 0.75%
  • Over 50 lbs: 0.75 – 1%

Don’t give a full-body massage with oil blends unless applied in a shampoo and washed off.

Now onto inhalation. Because their sense of smell is so much better developed than ours, we’re going to use way fewer drops in our diffuser. 1-2 drops per 100mL in a diffuser (most diffusers are around 100mL), for 1-10 mins every few hours is recommended.

Cautionary Essential Oils

The following essential oils may be potentially hazardous with regular continued use:

  • Almond (bitter)
  • Birch

There may be risks of neurotoxicity with the following oils, but it’s really only of concern if using large amounts or if you have nervous system problems. You’ll see Peppermint and Lemon on the list—I use these all the time! They’re great for most people. But, if you do have existing nervous system ailments, use the following with caution or avoid:

  • Lemon
  • Peppermint
  • Pine
  • Sage
  • Hyssop
  • Phenolic oils

The following oils can have convulsant effects (again, this typically pertains to extended use in individuals with preexisting conditions):

  • Hyssop
  • Camphor
  • Mugwort
  • Sage
  • Wormwood
  • Thuja

Don’t use Rosemary if epileptic.

There are also a few essential oils that can have psychotropic effects (= they affect mood/behavior or are even hallucinogenic). It may sound more like a fun Saturday night than a safety precaution, but it’s worth noting the following 😉 :

  • Nutmeg – Nutmeg contains myristicin which increases levels of serotonin and gives a euphoric feeling, but this applies more to ground nutmeg than the essential oil.
  • Thujone-rich oils – Thujone is an active ingredient in cannabis (weed—I feel awkward calling it “cannabis” but I’m trying to sound professional here haha) and it has a similar effect in oils containing it.
  • Anethole

Some essential oils (mostly citruses) can have a phototoxic effect. This means they induce a skin reaction in the presence of strong sunlight. The following are wonderful essential oils, just don’t apply a blend containing them to your skin prior to going outside on a sunny summer day.

  • Bergamot
  • Lemongrass
  • Lime
  • Orange
  • Angelica root
  • Cumin
  • Lemon
  • Grapefruit
  • Tangerine

Also avoid using these oils regularly on moles, melanoma or any other skin cancers.

Those are some basic safety guidelines to keep in mind when using essential oils in your every day life. I’ll go into specifics with every blend I post and essential oil I profile in the future so if you’re left with some questions, fear not. (Or just ask them in the comments section!)
