What’s the Deal with Essential Oils?

The good, the bad, and the ugly

You can diffuse them, they help people de-stress, they are in cleaning supplies, some even have antibacterial properties. No wonder they are literally everywhere these days.

So first off, what are they? Essential oils are what make certain plants and fruits smell the way they do. Those little bottles we are used to seeing them in now is what happens after they have been carefully extracted from the plant and bottled. It's important to realize that it can take hundreds of pounds the real life plants to get enough essential oil to fill those little brown bottles we are so used to seeing. So, basically, that means essential oils are super strong.


The Good

If used properly, there are many studies showing the effectiveness of essential oils for a variety of applications, including stress relief (like chamomile) and antimicrobial treatments (like tea tree oil). Also, since they come directly from plants that grow in nature, they can be a natural, chemical-free way to achieve these outcomes.

Because they are oils, they are also extremely versatile. They can be diluted in carrier oils, like coconut or canola oil, and diffused to make a room smell pretty. Or, they can be added to cleaning supplies or DIY solutions to mask the smell of the cleaning agent without adding any "fragrance" chemicals, which have been shown to contain a mixture of up to 200 other chemicals, some of which are associated with health issues like infertility and asthma.

The Bad

While essential oils occur naturally in our world, it doesn't mean they are without risk. The risk generally comes from the fact that essential oils are so strong. If used properly, they are generally agreed to be pretty safe, but if you use too much they can become dangerous, and in some cases cause pretty nasty reactions. This depends on the type of essential oil, and how much of it you use, but there are quite a few documented cases of people getting sick, developing burns from skin contact (1), or even hospitalization if ingested.

The Ugly

As essential oils have become extremely popular over the last few years, we keep learning more about how they interact with our world and our bodies. One thing that has come up is learning that certain types of essential oils, namely lavender and tea tree oil, can mess with people's endocrine systems. This means that your body's natural hormone processes get screwed up, and in certain cases regularly using products with lavender and tea tree oil has been found to cause prepubescent boys to start growing breasts. (2) The good news there is that when they stopped using the lotions, soaps, and hair gels with lavender essential oils, the problem resolved itself - whew! But, this just goes to show how powerful these oils can be on your body, especially if you use them all the time. Remember, each drop is like walking around with pounds of that plant on you, so use them sparingly.

A Warning

Another consideration to keep in mind when using essential oils is that not everyone responds to them the same way. Often babies, children, and pets are more sensitive to them, so even small amounts can irritate them. We'd say go very easy on using essential oils or products that contain them in or around your baby, and ask your doctor or pediatrician if you are nervous or have questions. (3)

Same goes for pets. In general, both cats and dogs have way better senses of smell than people do, so what might smell pleasant in a large room to us, might be extremely overwhelming for your pets. (4) Also, be careful that they aren't accidentally licking the essential oils in any way. Just because they are safe for humans to use, does not mean they are safe for cats and dogs to eat. Bottom line, just be aware of your pets around essential oils and make sure they don't seem to be bothered in any way by them. If you are nervous, talk to your vet about it first.

The Verdict

Essential oils should be used carefully and in moderation. Don't just run with the idea that they come from nature, so it's safe to use large amounts all the time. While you want to use them in moderation, we do suggest using essential oils properly instead of other things like candles or "fragrance" including body wash if you want a way to smell fresh and beautiful all day.

    What to Know Before Your Next Big DIY Project

    Protect your health without sacrificing creativity!

    Whether you're inspired by a recent Etsy binge or are a Weekend Warrior who practically lives at Home Depot, DIY projects can be super fun and fulfilling. Before you get started on your next project, we have some tips on what chemicals to avoid, the safety hazards they pose, and ways to keep yourself safe.




    Avoid Methylene chloride

    It's always fun to spruce up furniture with a new coat of paint but methylene chloride, a seriously dangerous chemical, is found in paint stripping products. In the body methylene chloride turns into carbon monoxide (1), and too much carbon monoxide can cause dizziness, confusion, and asphyxia. Methylene chloride fumes quickly accumulate and are heavier than air, which means workers bending down over projects in poorly ventilated areas are easily susceptible to the dangers of this chemical (2). There have been many accidental deaths from Methylene chloride, so you should completely avoid paint strippers that use it. Safer Chemicals, Healthy Families has created a great reference on safer alternative for paint strippers.

    Paint

    Before you pick up your paint brush to tackle that dresser revamp, make sure the paint you're using is low VOCs. VOCs, or volatile organic compounds, are chemicals that are emitted as gasses from products like paint and can cause headaches, eye irritation, and nausea (3). VOCs are part of the reason paint can be so smelly when it's drying! Look for a paint that says low or no VOCs on the packaging and make sure to keep the windows open while the paint is drying!

    Wood Stains

    Updating your wood table or decking? Reach for a water-based wood stain or finish! Traditional wood stains can contain harsh chemicals and emit a ton of VOCs. Luckily a lot of brands have a VOC rating on their label, which makes choosing a product a lot easier. We recommend choosing a stain with low VOCs (under 250 g/l) that is also Green Seal 11 (GS-11) certified (4).

    Always Have Proper Ventilation

    This is key for any DIY project. Chances are, you'll probably use some chemicals that are not great for you during your project. The best place to work on your project is outside but if you have to work indoor, make sure to open windows and doors, and use a fan to ventilate the area.

    Wear a Protective Mask

    DIY projects can expose you to a TON of dust, which is why it's a good idea to always wear a protective mask. Dust is bad for you in general, and can also contain particles containing toxic chemicals, which is why we recommend using an N95 mask while working. Normal masks can help protect you, but they don't protect you from all dust. N95 masks filter even the tiniest particles (0.3 microns) (5), which can keep you safe during those extremely messy projects.

    Now that you've invested in some glass and stainless steel food storage containers, maybe you're wondering if you should Marie Kondo all the plastic ones you used to use? Instead adding them to the landfill, what if we told you that all those plastic containers can help you achieve a new level of organization zen? While we don't recommend storing food in them anymore (for those of you who haven't heard: these plastic food storage containers often have BPA or phthalates in them, which can leach into your food over time and cause all sorts of health problems), we also don't think you have to throw them away.

    So, what can you do? We have 6 great suggestions for you to repurpose those containers throughout your home.

    Banish Bugs With Our Recommended Insect Repellent Ingredients

    Don't be an all-you-can-eat-buffet for annoying critters again!

    Summer is here! But that means so are the biting insects…. Ugh. Mosquitoes, ticks, chiggers, fleas, and biting flies seem impossible to avoid when the weather heats up. They're really annoying and they can post a pretty big health risk. Mosquitoes and ticks alone can transmit some scary diseases like Zika, Lyme, malaria, encephalitis, and dengue fever. And to make matters worse, a new CDC report shows the number of mosquito and tick-borne diseases are on the rise (1). To help protect yourself against these pesky insects, we're discussing the most effective insect repellent ingredients that are EPA registered (AKA safe and effective) and CDC recommended: DEET, picardian, and oil of lemon eucalyptus.

    We know what you're thinking- synthetic chemicals are recommended?! In this case, the risk of disease is a bigger environmental health threat than using these two specific synthetic chemicals. Additionally, there have also been no scientific studies that show essential oils are effective in protecting against insect bites so we can't include them in our recommendations. You can try them and maybe they'll work for you, but there's no guarantee. If you really want our one DEET alternative, non-synthetic repellent recommendation, that has a transparent list of ingredients, and is scientifically proven to keep bugs away, stay tuned!

    DEET

    DEET (N,N-diethyl-meta-toluamide) is considered to be the "gold standard" of insect repellent. It's a good choice if you're outside all day in a high-insect are because it repels the most insects, including both mosquitoes and ticks, and lasts the longest amount of time (2). When applied correctly (make sure to read the label!), there are very few negative reactions from DEET. A product with a concentration of DEET between 20-30% can provide protection from insects for most of the day (3). DEET can be used while pregnant and on children older than two months and has not been found to be carcinogenic. Although some may see dermatitis or an allergic reaction from long-term exposure to high levels of DEET (2) and oral ingestion has been shown to have neurotoxic effects like seizures (4).

    Picaridin

    Picaridin (icardian) is another repellent ingredient that repels ticks and mosquitoes. It's been widely used in Europe and Australia for years with positive results. A product containing at least 20% picaridin has similar short-term results as DEET, although picaridin does not provide long-lasting protection as well as DEET and has to be reapplied more often (2). Picaridin has not been studied as thoroughly as DEET, but it does not seem to have any major negative health impacts. Although uncommon it can cause skin or eye irritation, so make sure to read the directions when using a product containing picaridin (5).

    Oil of Lemon Eucalyptus

    Oil of lemon eucalyptus (P-menthane-3,8-diol) is a natural oil extracted from the lemon-scented eucalyptus plant (6). It can be an appealing ingredient to people because it's an alternative to synthetic chemicals like DEET or picaridin. Oil of lemon eucalyptus is great at repelling mosquitoes, flies and gnats, but not so great against ticks (2). Products containing at least 30% of oil of lemon eucalyptus have shown to be almost as effective as repelling mosquitoes as DEET, but it has to be applied much more frequently (6). While it is natural, it can irritate the eyes or skin and is not recommended for children under 3 (7). Just a quick note: lemon essential oil and eucalyptus essential oil are NOT the same thing as oil of lemon eucalyptus though, so make sure to look for that exact phrasing in any ingredient lists.

    Since oil of lemon eucalyptus is EPA registered and a natural ingredient, we think it's a great synthetic-ingredient alternative! We love Murphy's Naturals Lemon Eucalyptus Oil Insect Repellent Spray. It uses 30% oil of lemon eucalyptus as a way to repel those annoying bugs and lists all of the ingredients (ethanol and water). It's super super hard to find a complete list of ingredients in insect repellent products, so we think this is a huge plus.

    So which ingredient should I choose?

    It depends! Are you in an area with a high amount of mosquitoes and ticks? Are you outdoors for the entire day or maybe just an hour? Do you want to avoid synthetic chemicals or are you okay with it? Are you traveling to a place that has a high rate of diseases like malaria or yellow fever? The EPA has a quiz you can take in order to find the best insect repellent for your needs.

    We recommend to always read and completely follow the directions listed on any repellent product you use, and wash your hands after applying a repellent. Generally you want to apply repellent when you're outside while holding the product at least 6 inches away as you spray. While spraying repellent on your clothes is okay (although DEET shouldn't be sprayed on synthetic fabric), it's not a good idea to spray it under your clothes (8). Long sleeved shirts, pants, long socks, and closed toe shoes can reduce the risk of a bite because less skin is exposed.

    Now that you're fully up-to-date on the best insect repellent ingredients you can go back to focusing on what really matters: barbecuing, swimming, beach trips, and all of fun activities that come with summer!
