What are Essential Oils?

Essential Oils From Plants

To sum up the many years of my understanding on essential oils, I would define essential oils as highly concentrated natural oils extracted from different plant species.

It has been used as a part of “Natural Medicine” (also “Alternative Medicine”) since the ancient times.

Essential oils contain the “essence” of a particular plant, locking not only the flavor and scent of a plant, but also the therapeutic ingredients in them. This "essence" is usually gathered from the roots, stems, leaves, flowers or even fruits of a plant.

Do remember that not every plants produce essential oils, and not any "essence" from any plants are safe - Paclitaxel extracted from the Pacific yew is a chemotherapy drug, this is why you need this guide, to tell you what is safe and what is not.

There could be over 200 properties contained within different essential oils, hence you will notice a lot of essential oils having overlapping healing properties, but some are better than others in augmenting the therapy of certain diseases.

Just How ‘Ancient’ Are Essential Oils?

Ancient Egypts Extracting Essential Oils

The quick answer to this is: It is very, very, very ancient…

Imagine ancient Egypt (think ‘Pharaoh’). Yes. That long ago.

The earliest use of essential oils can be sourced back to 3000-2500 B.C.

Though, it played many roles in the past, including medicine, ceremony, religious observances, beauty care, food preservation, and also perfumes. 

Ancient Egyptian is considered the earliest culture that started using them, but there are also evidence that pointed out both China and India had started using essential oil-like extracts in their medicinal treatments around the same time.

Forgotten for many years, it was only very recently that the medicinal properties are put under the spotlight.

How Are Essential Oils Extracted From Plants?

I know you feel the urge to skip this topic, but just like knowing where your organic food comes from equips you with the knowledge to distinguish between real organic food and fake organic food, learning a bit of essential oil jargon will help you make wise decisions on getting essential oils for yourself.

How essential oils are obtained determines the "purity" and "effectiveness" of the oils.

(Note: Essential oils that are obtained through chemical processes are NOT true essential oils)

There are 2 key methods that are used to extract essential oils:

  • Steam Distillation
  • Expression

Steam Distillation

Steam distillation has long been used to extract essential oils, long before alchemy came about.

  1. The steam is directed through the plant material inside a sealed still.
  2. The steam will then vaporize the lighter chemicals contained within the plant material.
  3. Guided via a connecting pipe, the vapor will be collected into a condenser, which cools the vapor into liquid form again.
  4. This process generates 2 products, essential oil & water
  5. Since water and oil don’t mix, essential oil can be easily siphoned out.

Until today, steam distillation still remains the most common process of extracting essential oils from plants.

Reason being, distillation has the ability to distill volatile components at temperatures lower than the boiling points of their individual constituents, hence maintaining the basic structure of essential oils. Also, it is easier to separate essential oils from water.


Expression, also known as “Cold Pressing”, is a method used to extract essential oils from citrus fruits, such as: lemon, tangerine, lime, sweet orange etc. This is because citrus oils will be damaged when heat is used in the process.Think of it this way, imagine pressing the liquid out of citrus fruits through a fine filter.

You then collect the filtered liquid, letting it stand for many hours so that the essential oil and juice separates.

Once that’s done you can siphon out the essential oil.

Chapter 2: What Are The Benefits of Essential Oils? What Are They Used For?

For over 5,000 years, across various countries and cultures, essential oils have been used in 2 main areas, namely,

1. Improving overall health

2. Treating certain diseases

According to The Ohio State University, because of their obvious health improvement properties, such as detoxifying, antidepressant, antiviral, antibacterial, calming & even stimulating properties, essential oils are regaining its popularity among the public as a natural, safe & cost-effective supplementary medicine to support proper treatments.

Essential Oils Can Help You In 12 Ways:

#1 : Boosting Immune Systems (Fight Infections)

First of all, boosting immune system is a “BIG” word, as immune system is a very complex thing.

Some essential oils contain antiviral, antibacterial, antifungal, and even anti-inflammatory properties, they are able to improve your immune system and also fight infections naturally, mostly in the form of combination therapy with modern treatments.

In most cases, an essential oil is said to have the ability to “boost” ones immune system by usually only augmenting one or two key areas.

For example, one essential oil can be antibacterial, but not antiviral.

One way these oils fight infection is to stimulate the production of white cells, which are akin to the soldiers of your immune system.

While other oils can encourage new cell growth to promote faster healing…

...Some oils even effectively destroy several fungal, viral and bacterial pathogens, including methicillin-resistant Staphylococcus aureus, Helicobacter pylori and Candida albicans infections.

Best essential oils that can serve immune system boosting purpose are oregano, myrrh, ginger, lemon, eucalyptus, frankincense, peppermint and cinnamon.

#2 : Relieving Body Aches & Pains

Pain is essential. It is an alarm system given out by your body, reminding you to fix something that went wrong in you. Imagine that you do not feel pain when your foot gets wounded, you will not tend to it, and eventually it will be infected and yea, say goodbye to your foot. This is a condition we call diabetic foot ulcer.

However, some pains are an overreaction of your body's alarm system, and hence irritating and debilitating, both fibromyalgia and postherpetic neuralgia are typical examples of such pain. 


This is where essential oils come into play. Essential oils reduce pain by reducing inflammation and pain-related cytokines (or you could call them "pain molecules").

A personal favourite of mine is peppermint essential oil, it contains “menthol”, which acts as an antispasmodic and a mild analgesic, which helps to reduce pain, pressure and tension, this is a gospel to many of us who suffer from frequent muscle aches.

Lavender essential oil contains mildly but active sedative compounds that has been used for pain and pressure relief for centuries. It also contains anti-inflammatory and analgesic property when used topically. Basically, besides taking away the "pain molecules", it stimulates the production of "happy molecules" - dopamine in your brain.

In summary, the best essential oils for relieving aches and pains are lavender, peppermint, eucalyptus, chamomile, rosemary, majoram, thyme, frankincense, turmeric, ginger and myrrh.

#3 : Improving Skin Care


Acne is really a bummer. Acne is generally caused by clogged pores trapping sebum in the pores, hence providing both anaerobic environment and food source for the bacteria Proprionibacterium.

With the antibacterial and anti anti-inflammatory benefits many essential oils possess, coupled with their superiority in regulating oil production and reducing acne breakouts, acne can be easily controlled. Some also help improve skin elasticity and tighten skin, reducing appearance of wrinkles.

Besides that, some oils promote blood circulation to the applied area, which helps to heal bruises, burns, cuts, broken capillaries, ringworm, eczema and other skin conditions.

But remember, everyone's skin is different, always consult a dermatologist before applying any of the essential oils onto your skin or wound.

#4 : Improving Hair Growth

There are many reasons to why you are not growing thicker hair like you wanted, or worse, you’re losing hair!

It could be caused by physical & emotional stress, hormonal imbalance, harmful chemicals, insufficient vitamins, allergies, heredity and more.

Different oils have different properties that tackle the different mechanism of hair loss.

#5 : Supporting Digestion

A good digestion is the cornerstone to good health. Do you know that certain part of your guts are responsible for certain breakdown or absorption of different nutrients? For example, terminal ileum is where iron is absorbed, with the help of a cofactor (a type of protein). 

It is important to note that, digestive problems are not illnesses, they are symptoms of underlying conditions, sometimes chronic even.

Common gastrointestinal symptoms that might bug you are constipation, diarrhea, vomiting, heartburn, stomach spasms and other similar symptoms.

Essential oils help by regulating digestion, so that your digestive system becomes more efficient in breaking down and absorbing the fat, protein and other important nutrients.

Ginger essential oil is highly recommended due to its anti-spasmodic properties, while at the same time soothe your intestinal linings. It also has carminative effect, which helps you release any gas out of your body. Ginger is also a proven remedy for nausea and vomiting in pregnancy.

Unlike amphetamine that floods your brain with dopamine and hence causing addiction, the calming effect of essential oils is very long-lasting, resulting in a relaxed and healthy body.

In other words, these go without the harmful side effects of synthetic medications, such as sleeping pills.

Lavender essential oil is the one when it comes to incredible soothing and calming effect. It helps in calming your nerves by aiding sleep, restlessness, and general tensions.

Essential oils play a primary role here because it treats headaches to the root cause, without the ugly side effects that painkiller gives you, such as kidney and liver damages.

Headaches can be caused by hormonal imbalances, stress, intensive physical exertion, sinus pressure, allergies, or even certain food consumption.

These are the things where essential oil can help with, for example, peppermint oil can help muscle contractions and also stimulate blood flow in the forehead when applied.

#8 : Helping To Sleep Better

Sleep is one of the most important part of a human life.

A quality sleep time can help you stay energized throughout the day and improve health and even productivity.

Essential oil can be used to help sleeping in two ways. Firstly, you prevent insomnia by calming your mind and reducing anxiety. Secondly, you prevent harmful sleeping habit such as snoring and sleep apnea by clearing your airways.

The right essential oils provide not just the flowery scent that calms your mind, but also the soothing effect to relax your muscle and nerves. All of which contributes towards a high quality sleep.

A better way to leverage essential oil for sleep is to make an essential oil blend, this will improve your sleep quality even more than what a single oil would do.

#9 : Detoxifying Your Body

We are never free from potential pollutants in our everyday lives. The food you eat, the air you breathe in, the water you drink, the things you touch, not one of them is clean.

Essential oils in this case, can serve as effective diuretics, increasing our urine production, thus speeding up the excretion of waste materials in our body.

According to NCBI, some plants are also able to boost the detoxification function of the liver. This is done on the grounds of the hepatoprotective (liver-protecting) and antioxidising properties of those plants.

Also, due to the antiseptic properties of some essential oils, when in contact with harmful pathogens, can dismantle the pathogens and thus detoxifying the environment around us. This is especially true when science

Also, on a smaller scale, essential oils are able to improve cognitive functions, such as memory and attention, even in those who are not at risk for developing dementia.

For instance, a main compound found in rosemary called “Eucalyptol”, can enhance the brain’s ability to absorb and retain information. You will notice things like improved memory and mental alertness.

Hormonal imbalance can cause us a lot of issues, such as mood swings, rage, anxiety, fatigue, sad, depressed, even worse, suicidal.

By balancing hormone levels such as estrogen, progesterone, cortisol, thyroid and testosterone levels, the hypothalamus is very important to our daily physiological functions, like, body temperature, thirst, hunger, sleep, mood, even sex drive.

For ladies, oils like clary sage, geranium and thyme helps in balancing estrogen and progesterone levels, which greatly improves fertility and help conditions like PCOS and PMS.

Although I stand by SoothOil Essential Oils firmly, but I cannot deny the fact that it is DANGEROUS to use essential oil without proper knowledge.

In this chapter you will learn four main methods to use essential oils to improve your life, and also how to permanently harm your skin. (LOL)

Here we go...

Although essential oils are commonly used diluted with carrier oils, there are some discussions about using these oils “neat”, meaning, using essential oil without first diluting with carrier oils.

..Please do not use them “neat” . Period. (Not even Lavender oil!)

Sales companies and salesman will often tell you that using essential oils neat is totally safe and will maximize the benefits and effects of the essential oil.

This is so that you will buy more oils from them.

But the truth of using them neat is the complete opposite of what you think…

Even with mild essential oils such as Lavender Oil or Tea Tree Oil, using them neat will actually impose a long term or permanent sensitization to that essential oil.

It doesn’t happen all the time, but there are chances that once you’re sensitized to the essential oil, it’ll cause irritation each time you use it for the next few decades.

Using diluted essential oils will not decrease the benefits and effects of it. In fact, it is highly recommended to use it with carrier oils, as it is the safest way to do.

Whether you’re a beginner or you have some knowledge about essential oils prior to this guide, there are four general ways for us to apply essential oils onto our body correctly.

4 Main Ways To Use Essential Oils

#1: Inhalation

Inhaling Essential Oil

Inhalation is the easiest and the fastest way to get the essential oils into our bloodstream.

For beginners, it is always recommended to use direct inhalation method first in order to see how well or how bad you react to it. This involves bringing the essential oil close to your nose and sniffing it.

Be careful not to sniff too strongly as there's a chance of sniffing in the microparticles around the bottle.

Indirect inhalation is another inhalation method that allows us to inhale the aroma of the essential oil without directly sniffing the bottle.

You could apply the essential oil onto small items such as cotton balls or cloth to keep your mood elevated.

(Note: I personally love spraying a small amount of lavender onto my bed sheet to have a more peaceful sleep!)

#2 : Diffusion

Essential Oil Diffusers

This method allows essential oils to be evaporated into the air via the use of a diffusion device.

Diffusion is good for getting rid of unwanted odor in your room. It also helps to promote your sleep quality and reduce stress level.

However, there are various ways to diffuse essential oils, such as using an essential oil burner, evaporation or reed diffusing, using a tissue, nebulizer, spraying, and many more!

We have a detailed guide here on each diffusion methods, how to use them correctly, and what are the important things to keep in mind while using each of them.

#3 : Topical

Applying Essential Oil Topically

This method involves directly applying essential oils onto the skin.

WARNING: Before we proceed, it is worth to noting that you should always dilute the essential oil before applying them, even if it is a mild type like Lavender Oil.

Usually, we dilute the essential oil with a carrier oil such as Jojoba to a concentration not more than 3-5%.

A safe way to create a 3% concentrated essential oil is to use one teaspoon of carrier oil with 3 drops of essential oil.

If you’re still reluctant to use essential oils onto your skin, you can consider using them on your feet to test, since the skin is thick and less sensitive, and are far away from mucous membranes.

#4 : Bath

Bathing With Essential Oil

Bathing is one of our daily needs, so why don’t we get the most out of it?

WARNING: Before starting your aromatherapy bath, you must not add essential directly into your bath.

The reason is simple -

Oil is hydrophobic, it doesn’t mix with water at all. If you add essential oil directly into your bath and just hop into the bathtub, the highly concentrated oil has a direct contact with your skin, and guess what..?

...You might end up with a long term sensitization with the oil, again.

The only way to achieve this is to first mix essential oils with carrier oils like Jojoba or Coconut oil, then mix them into your bath. The optimal concentration is to add 3 to 12 drops of essential oil into one tablespoon of carrier oil.

This concentration is relatively higher than the concentration you use topically, but not to worry, because the entire tub of water will further dilute it for you.

Depending on how you combine the essential oils in your bath, you’ll experience different benefits.

Aromatherapy bath can boost your mood, relieve your stress after a long working day, keep you relaxed throughout the day, cure headache, increase focus, get rid of allergy, and many more.

We have a detailed guide here on how to prepare the essential oil for your bath, and what combination works best for you.

Chapter 5: What Are Carrier Oils & Why Are They Needed?

As the name of it suggests - “Carrier”, its main purpose is to act as a base to ‘carry’ the essential oils onto your skin.

Given the fact that oil does not mix with water, the only liquid to dilute essential oil is to use a carrier oil. You use a carrier oil to dilute the essential oil before applying it to your skin.

Why, you ask?

Because if applied undiluted, essential oils or any concentrated aromatic oils can cause severe sensitization, redness, irritation or other unwanted reactions.

Carrier oils are vegetable oils, extracted from the fatty portion of a plant, such as the seed, kernels and even nuts. They do not evaporate, and generally has very faint scent (usually sweet and nutty).

Top 5 Picks For Carrier Oils To Have At Home

Below are the top 5 essential oil carrier oils that we highly recommend to have at home (or you can keep just 1 or 2 types):

#1 : Jojoba Oil

If you’re new to this carrier oil, you’re likely to pronounce it wrongly. It’s okay! The correct pronunciation is to read it as “hohoba”, instead of just simply reading “jojoba”.

Although it is slightly more expensive than other carrier oils, it is by far the best choice among all. It consists of eicosenoic acid, a long omega-9 fatty acid that couldn’t be digested by humans, but highly resembles our body’s natural oil, and therefore absorbs well into our skin.

Jojoba oil is also rich in vitamin A and E, further helping in acne prevention and cure. Due to the fact that it has the longest fatty acid chain than other carrier oils, it naturally has a long shelf life.

However, it contains a slight nutty aroma, and might interfere with other aroma of essential oil.

#2 : Coconut Oil

Being one of the most famous carrier oil, coconut oil is a well known antioxidant, antifungal, anti-inflammatory and antibacterial agent. It remains as a solid state in room temperature, but melts instantly when applied topically.

Coconut oil branches out to two types, unrefined and refined. We recommend using unrefined coconut oil as it doesn’t go through chemical extraction process.

The refining process will cause the oil to lose some of its therapeutic properties.

Unrefined coconut oil contains lauric acid that prolongs the shelf life of the oil. However, it has a strong aroma that will interfere with essential oil.

The refined or fractionated coconut oil, in the other hand, doesn’t have any scent, and never stain clothes. It remains as a liquid state in room temperature.

#3 : Olive Oil

This oil can be widely found in kitchens. It is rich in antioxidants and phenol, effective in soothing the skin. Oleic acid, one of its main components, plays a role in improving heart and cardiovascular system.

However, it has a fruity scent, and might interfere with the fragrance of the essential oil that you’re using. Also, upon topical application, it is thicker and more oily.

#4 : Sweet Almond Oil

This oil is not only good for moisturizing and skin nourishing, its high level of vitamin A, D and E also makes it a great oil for dry skins. As compared to Olive Oil, this oil is more scentless, and will not interfere with the aroma of the essential oil.

However, it needs to be stored in the refrigerator, while the other oils can be stored under room temperature.

#5: Avocado Oil

This highly hydrating oil suits best for youthful skins. It naturally contains high amount of fatty acids and vitamins, and is perfect for building up skin collagen.

However, similar to Olive Oil, it is thick and oily, and therefore doesn’t absorb well into skin pores.

WARNING: Mineral Oils Are NOT Carrier Oils

Nowadays, many companies are using mineral oils as a substitute of carrier oils since it’s significantly cheaper, and they’re mostly used in baby oils and commercially available moisturizers.

However, these petroleum byproducts will actually clog skin pores and prevent your skin from absorbing essential oil.

Chapter 6: What Are The Types of Diffusers and How Do They Work

#1: Heat Diffuser

Heat Diffuser

As the name suggests, this type of diffuser heats the essential up until it evaporates into the air.

The two common types of heating method are electric heat and candle heat.

If you’re considering using a heat diffuser, you may want to choose electric heat.

The flame source of a candle heat diffuser is always a risk (it can cause a fire). It is best to avoid using this type of heat diffuser in the public for safety purpose.

On the other hand, electric heat diffusers uses extremely small amount of energy to power the diffuser each day. It is not only economical, it is also safe to use. Due to the string benefits over the candle heat diffuser, the electric heat diffusers are gaining more popularity over the years.

Nevertheless, heat will potentially change the nature and properties of the essential oil. Therefore, you won’t be able to fully enjoy the full benefits of the essential oil.

#2: Evaporative Diffuser

Similar to heat diffusers, this type of diffuser also distribute the oils via evaporation, but using a fan instead.

Evaporative diffuser uses a fan to evaporate the into the air while the essential oil is held in an absorbent material such as a pad or a wick.

This diffuser emits the oil in a controlled fashion, thus releasing a steady amount of essential to the atmosphere.

#3: Ultrasonic Diffuser

This type of diffuser uses kinetic or vibration to breakdown the essential oil into microparticles, and disperse them into the air as anionic particles.

The entire process is extremely quiet, perfect for sleep and relaxation.

There are several advantages of using this type of diffusers as compared to heat or evaporative diffusers.

Firstly, ultrasonic diffuser is not powered by heat, hence keeping essential oils "untouched".

Secondly, the ultrasonic diffuser also acts as a humidifier for your room, since the dispersion process involves the use of water, the dispersed steam will dilute the aroma of the essential oil (perfect for those who doesn’t like strong aromatic environment).

However, do take note that the prolonged exposure of moisture in the inner wall of the diffuser is a conducive for growth of fungus, therefore, remember to clean it often.

#4: Nebulizing Diffuser

Nebulizing diffuser is so far the best among all types of diffusers.

A nebulizing diffuser works by breaking down essential oils with force.

It does not require any heat or water, therefore releasing the most concentrated and purest form of essential oil into the air, making it the best option for aromatherapy.

The aroma released from a nebulizing diffuser covers up to 400 square feet, approximately the size of an entire studio. The electrical consumption is minimal, and it does not add moisture or humidity in the air of your room. So if you’re staying in a fairly humid area, this works perfect for you.

However, this type of diffuser consumes more oil than the others. Therefore, we will always recommend our customers to place a timer beside so that you will know when to stop it. Alternatively, some of the best nebulizing diffusers that we mentioned in our Top 5 list has built-in timers.
