The Ultimate Essential Oils Guide (Updated April 2020)

No two essential oils are the same, but this essential oils guide will help you make heads and tails of all this. Two or more oils may be quite similar to each other, but each has a unique chemical composition that gives it its particular aroma and set of properties.

Some essential oils have a floral scent, while some have a herbaceous, camphorous, woody, or citrusy scent. Some can relax you, while some can invigorate you. What all essential oils do have in common, however, is that they can improve various aspects of your health as well as your state of mind.

Essential oils are the natural aromatic essences of various plants. These essences originate in special plant cells found deep in the bark, rind, leaves, or flower petals. The essential oils are then extracted through natural methods—either steam distillation or mechanical pressure. These two processes produce the highest quality of essential oils.

Chemical processes can also extract the essences of various plants, but these extractions are not actually considered to be true essential oils. Aroma Foundry’s essential oils are extracted from high-quality sources through either steam distillation or mechanical pressure, so you can be sure that you are indeed purchasing genuine 100% natural essential oils.

On this page, you’ll find a comprehensive guide to essential oils. You’ll learn more about the history of essential oils, what scientific studies say about them, how to safely use them, what types of fragrances they produce, and what kind of diffusers there are.

      Essential Oils in History

      essential oil factsNumerous historical accounts detail the use of essential oils in many ancient practices, including medicinal methodologies, embalming, bathing, and perfumery.

       

      Essential oils have been used in home remedies for hundreds of years. Different cultures around the world have specific uses for them, from religious ceremonies to the treatment of illnesses.

      Egyptians used aromatic oils and pastes from plants to make pills, powders, ointments, medicinal cakes, and suppositories. They also used herbs, oils, and fragrances in religious practices. Pharaohs were also known to have had their own special blends for meditation, war, and love, among other things.

      The use of aromatic oils in China was first recorded centuries ago during the reign of Huang Ti. The emperor’s book of internal medicine documented the uses of several aromatics, and this is still being referred to by Eastern Medicine practitioners to this day.

      Ayurvedic Medicine from India has been incorporating essential oils into various healing potions. The uses of aromatic plants and oils played an integral part in medicinal, spiritual, and philosophical purposes.

      The uses and benefits of essential oils were also known in Greece, Rome, Persia, and other parts of Europe. Essential oils were used in medicine, personal care, household applications, and perfumes. Ayurvedic applications and the burning of frankincense and pine were also recorded to have significantly reduced the spread of the bubonic plague.

      Essential oils have indeed come a long way in history. Mother Nature has blessed us with the essences of trees and plants to holistically support our health and improve our day-to-day living. There’s still so much more to learn about essential oils, especially when ancient wisdom can help us in our modern day issues.

      Cedarwood essential oil is believed to be one of the first essential oils extracted by mankind. It has seen thousands of years of use already, by the Egyptians who employed it to embalm their dead and the Native Americans who used it for purification ceremonies.

      While ancient cedar tree species are now rare, modern-day cedars are more than adequate for the production of the aromatic cedarwood essential oils we know and enjoy today.

It’s this strong and characteristic scent that gives citronella oil one of its best-known attributes: the ability to repel insects.

      As an insect repellent, citronella can help protect you against harmful insects, such as mosquitoes, that carry infectious and potentially deadly diseases. While this in itself is admirable enough, the oil actually has so much more to offer. It is full of compounds that can help treat a variety of ailments as well as help get rid of negative emotions.

Like other citrus essential oils, which are extracted from the rind of their respective fruits, grapefruit oil comes from the rind of the grapefruit (Citrus paradisi).

      While the grapefruit itself is mostly just suitable for eating, its essential oil has far more uses.

      Distillation method

      Extracting essential oils from citrus fruits like grapefruit can be quite difficult, since the oils are found deep in the rind. Thus, the oil is extracted through mechanical compression.

      Brief info on uses and benefits

      Grapefruit essential oil is often used in cosmetics, since it has the ability to help lessen the appearance of scars and blemishes. It can also help manage acne and balance your skin’s production of sebum. Grapefruit can also help cleanse the hair of dirt and dead skin, as well as help get rid of dandruff.

      Of course, grapefruit essential oil isn’t just for cosmetic purposes.

The essential oil distilled from ylang ylang flowers carry all of these benefits and more. It also has a sweet and distinct scent that makes it a favorite in the perfume industry.

      Distillation method

      The blooms are picked at nighttime because that’s when their scents are strongest, and they’re processed shortly afterwards. Unlike other oils that are also extracted through steam distillation, the process of making ylang ylang essential oil is divided into several stages and can take up to 14 hours. The essential oil batches collected during the first distillations are the purest and most aromatic.

      Brief info on uses and benefits

      In their native soils, ylang ylang has been used to help treat malaria, pneumonia, asthma, stomach complaints, and more. Ylang ylang essential oil, meanwhile, has been known to be an effective regulator of mood, blood pressure, and heart rate. It also has properties that could help ease menstrual pain and many other types of inflammation, and it could also help improve skin and hair quality.

      Blending with other essential oils

      Ylang ylang essential oil blends well with the following essential oils:

      • Patchouli
      • Bergamot
      • Rosemary
      • Cedarwood
      • Eucalyptus
      • Lemon
      • Grapefruit
      • Lemongrass

       

      Blending Essential Oils

      essential oil blendsMost essential oil users favor certain oils over others based on aroma and other qualities.

       

      You can definitely make your own aromatherapy blends at home and be creative according to your signature scents. The general rule of thumb is to make a 1:1 ratio with the essential oils that you’ll be blending.

      For example, if you want to make a spiritually purifying blend, blend 1 drop of patchouli, 1 drop ylang ylang and 1 drop tea tree. Try and test to see if you like the aroma of the resulting blends. From there, you can add more drops of a particular essential oil according to your preference.

       

      About Carrier Oils and Agents


      Why You Should Use Emulsifiers

      When you need essential oils for anything other than diffusion, its very important that you use emulsifiers. Like many other oils, essential oils do not mix with water.

      The heavier oil would just float to the top, and even when this type of solution is thoroughly shaken before each application, it could often result in uneven distribution. More essential oil could be dispensed at one particular time than in another.

      When essential oils are to be added to liquids besides other oils, they need something that could bind the unmixable elements together. Without that binding agent, some of the adverse effects you could experience include skin irritation, sensitization, damage to mucous membranes, or even burns.

      One prime example of when this could happen is if essential oils are added in its pure and undiluted state to your bath. It is always best to blend it first with bath salts, castile soap, or other carriers meant for bathing before stirring it thoroughly into your tub water.

      Other examples of emulsifiers include high-proof alcohol, organic gels like aloe vera, honey, and vegetable and animal fats. Note that while mixing essential oils with alcohol like vodka is good for household applications, it is often not a good idea for other uses.

      If a solution is to be used on the skin, rubbing alcohol may do just as well. Unscented lotion is another example of an emulsifier that’s often used in aromatherapy.

      When using emulsifiers, it is best to mix it first with the essential oils. Stir or shake the solution thoroughly and see if any separation would occur before adding water or other water-based ingredients. The exact ratio of the mix would largely depend on the type of essential oil used and the recipe being followed.

      However, please note that unless the resulting blend is to be mixed with something else for topical use, emulsification is not necessary when you blend essential oils with carrier oils. This is because the two types of oils have similar chemical structures and would naturally blend well together even without external assistance.


      Understanding Carrier Oils

      essential oil blendsThough essential oils work well individually, they can complement each other's qualities when blended effectively.

       

      Since essential oils are highly soluble in fats, any type of oil is technically viable as a carrier agent. However, which types are the best? The best carrier oils are those made by cold-pressing the parts of plants that are rich in fat, and this include the kernels, nuts, or seeds.

      Carrier oils are basically pure organic matter in liquid form and not “essences.” As such, they do not evaporate like essential oils do, nor do they contain much aroma. They can go rancid as well, unlike essential oils, so it is always recommended to check first if the carrier oil you’re planning to use is fresh.

      Though they generally do not have much odor, if there’s a trace of bitterness in these oils when you sniff at them, it’s a sign they might have gone bad. Note, however, that some carrier oils do have fragrances of their own. They would usually smell nutty or sweet depending on the type, but these scents aren’t cause for worry unless you don’t want them interfering with the fragrance of your essential oils.

      Carrier oils aren’t exclusively from plant material either. Some can come from animals or fish. While these types might not be ideal for use in aromatherapy, they can be used when making wound disinfectants, the way our ancestors used them.

      There are also many ways to produce carrier oils, but the best ones for topical use are those that had been cold-pressed—i.e., not processed using heat, or using only minimal temperatures—as well as those with high tocopherol or vitamin E content. Carrier oils that have these qualities won’t just be good for the skin, they will also typically have a longer shelf life.

      Note also that unrefined oils are best when it comes to topical use, which rules out the common cooking oils found in our kitchens as they’re usually heavily processed.

      Oils that are absolutely not ideal for use on the skin include mineral oils and other petroleum-based products. These could block the pores, thereby preventing optimal essential oil absorption while also blocking the passage of toxins out of the body. Heavier materials which may be used, on the other hand, are vegetable butters like shea and cocoa. These would typically be solid at room temperature, and they’re also best when made through the cold-pressing method.

       


      Coconut Oil

      essential oil blendsBecause of its many beneficial properties, coconut oil is one of the most popular carrier oils.

       

      Fractionated coconut oil comes highly recommended because not only is it relatively cheap with a long shelf life, it is also light on the skin, which allows for good penetration. This oil is also odorless, which means it won’t interfere with the scent of the essential oils it blends with.

      One drawback is that it’s been processed and most of its natural contents have been lost. If you want a more organic option, a better choice would be virgin or extra-virgin coconut oil.

      In colder temperatures, coconut oil tends to be solid at room temperature. It has a rich and distinct aroma of coconuts, and it can be beneficial on the skin all on its own.

      Sunflower Oil

      This oil is also relatively affordable and can serve a lot of purposes. The unrefined variant of sunflower oil has a thin consistency, is easily absorbed by the skin and therefore won’t leave an oily feeling, has very little scent, and has a long shelf-life.

      Olive Oil

      This oil is readily available in many households and could be used in a pinch. However, most aromatherapy practitioners do not favor it for cosmetic purposes because it tends to sit heavily on the skin.

      Avocado Oil

      Avocado is very rich in nutrients. While it’s also heavy and oily on the skin like olive oil, it is highly ideal for use on the hair.

      Jojoba Oil

      This oil is one of the best choices out there for skin-specific uses because its chemical composition is close to that of the oil our own skin produces. It is also ideal for use in massages because it contains its own anti-inflammatory properties.

      Jojoba oil has medium viscosity but can be absorbed well by the skin. It also has a fairly long shelf life and won’t go rancid that easily.

      Sweet Almond Oil

      Sweet almond oil has its own subtle fragrance, which makes it a favored choice when making perfumes. While this oil is thin and light, it takes a while for the skin to absorb it. Like the other oils on this list, sweet almond oil is readily available, affordable, serves multiple purposes, and has a long shelf life.

      Other Carrier Oils

      Here are a few other examples of carrier oils that are often used in aromatherapy: canola oil, corn oil, apricot kernel oil, sesame oil, safflower oil, hazelnut oil, grapeseed oil, evening primrose oil, and many others.

      Your choice of carrier oils, just like your choice of essential oils, is definitely not limited. You might need to try several oils out to see which would best suit your particular skin type. It is also important to watch for a possible allergic reaction, especially for carrier oils like peanut oil.

       

      Diffuser Types Guide

      essential oil diffusersUsing diffusers or humidifiers is one of the easiest ways to enjoy the effects of essential oils.

      Depending on what you expect to get from your essential oils, there are various types of diffusers that you could use.

      If we’re talking about using the oils’ scents to create ambience in a room, for instance, a simple reed diffuser could do quite well. If you want to receive the full health benefits from your oils, however, investing in the more expensive and high-tech models might be necessary.

      To give you a much better idea of the types of diffusers available on the market, we listed the most commonly used types of diffusers and how each one is used.

       

      Heat-Using Electric Diffusers

      To use this type of diffuser, the essential oil is applied to the “pads” that typically come with it. Heat is then generated to gently raise the pads’ temperature, which would then slowly release the oil’s aroma.

      One pad can be dedicated to a specific oil, or other oils could be served up on top of another oil used previously to create a one-off blend. The pads can be changed after they’ve seen several uses and are beginning to fall apart.

      While diffusers like this are generally inexpensive, one drawback is that too much heat application can “cook” essential oils, and a lot of the health benefits you might be after would be lost in the process. Most models also only have a “diffuse” setting, meaning the device must be manually turned on and off. This might also account for why “cooking” accidents happen often.

       

      Ultrasonic or Humidifying Diffusers

      There are various makes and models for this type of diffuser, which could simultaneously moisturize and purify the air by using ultrasonic vibrations to send out molecules loaded with water and essential oil particles. That same benefit, however, is also its drawback. Because the oils require dilution with water to be sent out that way, you might need to use more drops at a given time to get the same amount of benefits as some other types of diffusers.

      Ultrasonic or humidifying diffusers come with water tanks that vary in size. The smallest ones typically have a 100 ml capacity, while the largest are 500 ml or more. These are often made from plastic materials that make them less ideal for cold-pressed citrus essential oils, which can be corrosive.

      Some manufacturers prohibit the use of citrus essential oils with their product outright, and some lower-quality models might have the same problem even with steam-distilled essential oils. These diffusers also need to be cleaned frequently.

      If you follow the manufacturer’s recommendations for using the diffusers, however, they would serve your aromatherapy needs just fine. After adding the required amount of water as well as the recommended number of essential oil drops, these diffusers can be run automatically in a set time.

      Some also have options where they turn on and off intermittently, which is especially useful since most experts would not recommend using a diffuser for more than one hour at a time.

      Nebulizing Diffusers

      Sometimes called atomizing diffusers, this type of diffuser is the most ideal if you want to get the maximum health benefits out of your essential oils.

      This type works two ways. First, it can produce a powerful and continuous burst of air to diffuse microdroplets of pure essential oil. Second, it can also turn the essential oil into mist or vapor that you can inhale or also absorb into your skin.

      Another thing that makes this type of diffuser ideal is that it doesn’t need heat or water to operate. It only diffuses essential oil particles, which makes for an even distribution within an enclosed space.

      Of course, it isn’t without drawbacks. The first would be the price—even the cheapest model could be more expensive than the most high-end models of other types of diffusers. Another is that it tends to be noisy, which might be irritating if you’re sensitive to low humming sounds.

      Last but not least, this type of diffuser tends to use up essential oils pretty quickly.

      With all that said, there’s no denying that this type of diffuser is more effective when what you need from your essential oils is treatment and not just therapy. Simply add the undiluted essential oil to the diffuser’s glass reservoir and run it at either low or high diffusion.

      Just remember that you should avoid using nebulizing diffusers for more than 15 minutes at a time. Overexposure can cause nausea, headaches, or emotional disturbances, among other things.

      Fifteen minutes at a time, however, is often enough to give your body and mental health the boost they need. It’s also best if you give yourself time to adjust to the effects of the essential oils.

       

      Oil Burners

      Like the electric diffuser, oil burners also use heat to disperse the essential oil into the air. They can be good for personal use or in small spaces in order to create an ambience while also perfuming the air.

      When applying heat to essential oils, however, some of their elements can become weaker or outright lost. This should be fine if you only want to enjoy the delightful play of scents and lights, but not so much if we’re talking about health benefits.

      To use, simply mix drops of essential oil with a bit of water on the small reservoir at the top of the diffuser. Light the candle which would ideally use low heat to gently disperse the oil and water mixture, and simply blow it out again after use. Please be careful not to leave the fire unattended.

       

      Other Types

      essential oil diffusersOne of the simplest and most efficient ways to use essential oils is with diffusers. Check out our list of DIY essential oil recipes that you can try!

       

      We’ve mentioned reed diffusers, which is an example of a non-electric, evaporative type of diffuser.

      Another popular example of this type of diffuser are terracotta pendants. The material would absorb the drops of essential and would let the scent out slowly when exposed to a passive heat source like sunlight or body heat. Their effects have even been known to last for days.

      These types of diffusers use little intervention to disperse essential oils and would let them diffuse as they naturally would, but this could mean that lighter components within the oil would easily evaporate. This might leave behind heavier components, which have benefits of their own. Again, terracotta pendants might be more ideal for decorative and scenting purposes and perhaps not so much for health-related uses.

       

      Types of Fragrances

      essential oil perfumesEssential oils have fragrances that are valuable to the creation of perfumes and colognes.

       

      The idea of classifying the fragrances of essential oils according to “notes” came from music. When composing a song, elements must be added so that the end product will produce a pleasing harmony. Some of the more powerful pieces of music can evoke thoughts and emotions in a listener.

      When done right, blending fragrances can also do the same.

      Fragrances are roughly divided into three categories of “notes” according to the length of time their aromas typically linger. Notes are either top, middle, or base. Top notes are those whose scents are the first to hit our sense of smell but would also be the first to dissipate, usually within the first couple of hours.

      Middle notes last from two to four hours, or even longer if they could also be classified as a “heart” note. A heart note is something in between two note types which, in this case, are middle and base.

      A good example of a heart note is the scent of ylang ylang. Middle notes are usually soft and warm, but they can be any type: sweet and floral, piney or woody, herbaceous or camphor-like. They offer balance to the blended scents as well as greatly extend the overall fragrance.

      Finally, base notes are scents that tend to be heavy, musky, earthy, and/or woody. Not only can these fragrances last for several hours longer, they’ve also been known to linger for days.

      They are typically “masculine” scents, but these darker scents have been gaining popularity among women as well because of their mysterious and longer-lasting appeal.

      In Aroma Foundry’s collection, the essential oils that are usually considered as top notes are basil, bergamot, citronella, eucalyptus, grapefruit, lemon, lemongrass, lime, spearmint, tangerine, and mandarin. The middle notes include sage, fir, rosemary, tea tree, and ylang ylang. Lastly, we have the famous base notes cedarwood and patchouli.

      It is important to note that the amount of drops to be added for a complete blend doesn’t always depend on which type of note an essential oil happens to be. For instance, even between top notes, one fragrance could be stronger and more overpowering than another, and this is the same across the board.

      This is why, in order to come up with a successful blend, some experimentation is often necessary.

       

      The Basics of Fragrance Blending

      To get started on making your own blend of scents, all you’ll need are small reusable bottles and a notebook or an electronic note-taking device to record the combinations you’ve tried. You can choose 5-ml bottles in the beginning: there’ll be less waste this way as you’ll only be blending a few drops each of essential oils.

      Note that you don’t have to limit yourself to just one essential oil per note. The beauty of blending is in how much room it gives you to simply explore.

      As you go along, take careful notes of the number of drops you’ve used for each essential oil per blend and consider if this combination hits the spot or if something needs to be added or subtracted. A simple way to test each fragrance is to add a few drops of the blend to a cotton ball and to let the notes play themselves out. You can then freely adjust from there until you arrive at the scent combination you like best.

      Once you’ve arrived at a blend you like, there will then be other things to consider. How would you like to use this blend? You could choose to run it as it is in your diffuser for up to an hour and let the scents linger for hours more, but you could also make a perfume out of your personal blend and carry it around with you wherever you go.

      Depending on which form you choose, whether as a mist spray, a roll-on perfume, or a perfume balm, you’ll need to gather other ingredients in order to process the essential oils further. This includes emulsifiers (typically high-proof alcohol), distilled water, and carrier oils.

      You will also need specialized containers that would not only store your resulting perfume but also protect the chemical integrity of their contents and extend their shelf-life.

      Essential oils are loaded with health benefits not just to the body but also to the mind and spirit. Making a hobby out of blending these essential for their scents could also be therapeutic in and of itself.

      Even though professional perfumers have to rely on chemicals other than essential oils and need years of study to master their craft, the basics of perfume-making are easy. All you’ll need is some creativity, an openness to the experience, and some trial-and-error to arrive at something you like.

      While there are rules that you can follow, the best thing about playing around with fragrances on your own is that you could make your own rules as you go. You may even end up learning a lot more that way.


      Common Precautions

      Basic Things You Need to Know

      • 100% pure and all-natural essential oils are less likely to cause adverse reactions, while oils with additives in them are more likely to be unsafe.
      • Some essential oils may be safe to apply topically in small amounts, while some essential oils should be diluted in carrier oils or other suitable substances before application.
      • If your skin is inflamed or damaged in any way, it may be more sensitive to essential oils and may thus be more prone to negative reactions.
      • Do not ingest essential oils orally.
      • If you have a health condition like diabetes or if you’re taking medication, you should first consult your doctor before using any essential oil. Essential oils can interfere with the effectiveness of your medication.

       

      Pregnancy and Children

      The use of essential oils in pregnancy is something of a controversial topic. According to some, if you use essential oils properly, it’s unlikely that it can negatively impact a developing fetus.

      However, there is still very little information that details how exactly can essential oils affect pregnancy. Thus, if you’re pregnant, you should consult your doctor before using essential oils.

      You should not use essential oils on children under the age of 7, since they may not be capable of withstanding the strong effects of the oils. While essential oils are all-natural and beneficial, they can also have adverse effects if not used properly.

       

      What is Phototoxicity?

      Some essential oils can be phototoxic. This means that they can make the skin especially susceptible to the effects of ultraviolet radiation. Potentially phototoxic essential oils include bergamot, lemon, lime, grapefruit, and other citrus essential oils. If you apply these oils on your skin, make sure that you don’t have to go out into the sun for at least 12 hours after application.

       

      Summary

      Essential oils are the distilled and bottled versions of the best that nature has to offer. However, like all things, they should be used properly and carefully so you can fully enjoy their benefits with little to no issues.

      Throughout much of the last two millennia, essential oils have proven that they can help manage various mental, emotional, and physical issues. From the first essential oils known to man to the more newly-discovered ones, each one offers a signature aroma and a set of diverse benefits.

      With this essential oils guide, you'll be able to explore the ways you can use and take full advantage of various oils.
