Aromatherapy DiffuserThe Most Effective Ways to Use Essential Oils

There are many ways you can use essential oils in your every day life, but some are more effective than others.  We’ll touch on what I think are the most effective ways to get the very best benefit out of your essential oil investment.


Inhaling essential oils which are dispersed by use of an aroma diffuser is the best way to get therapeutic value from your essential oils.  You should use caution though, as prolonged exposure and inhalation of essential oils can cause nausea, headaches, lethargy and dizziness.  It’s best to use them in short intervals throughout the day.  There are many types of diffusers to disperse essential oils and it’s important that you know the difference and choose the right diffuser for you.  Some of the favorite oils to use in diffusers are lavender, wild orange, lemon, white fir, peppermint, lime, grapefruit, geranium, eucalyptus, clary sage…just to name a few.

Aromatic Baths

One great way to use essential oils is to mix them with salts and then in with your bath water.  Aromatic bath salts help to disperse the oil at a safe level and prevent the drops of oil from just floating around in the water.  Not all oils are safe for baths, though.  Hot oils such as oregano, cinnamon, and thyme should not be used in the bath.  Also, phototoxic oils should be avoided in the bath.  These include oils like citruses, especially bergamot.  The most popular oils to use in baths are lavender, geranium, frankincense, clary sage, sandalwood, and eucalyptus.  A generally safe amount is 5 to 10 drops mixed into 1/2 to 1 cup of salt or another emulsifier like milk or sesame oil.  Aromatic baths are exceptional for skin problems, stress, respiratory symptoms, tension, nervousness, and muscular pain.  Use caution, however.  Overuse of essential oils can cause irritation so only use mild oils and do not use too much.


Usually made from gauze or some other type of soft material, a compress can be made and applied with some pressure to certain ailing body parts.  Compresses can help control hemorrage, support the body’s natural defense against infection, or help relieve pain.  Traditionally used for headaches, insect stings, bruises, sprains, swelling and blisters, compresses can also be effective with boils, dysmenorrhea, and absecesses.  Simply take the cloth and saturate it in a mixture of 9oz of water and 6 drops of oil.  Wring out the cloth and apply it to the body.


Therapeutic massage is one the most well known uses for essential oils.  Your nostrils are attached to a part of the brain called the limbic system which influences the nervous system and controls emotions. Therefore, when you inhale molecules from essential oils, messages are sent to the limbic system and immediately affects the heart rate, blood pressure, breathing, stress level, memory, digestion, and immune system.  The affect of essential oils are immediate which is why they are so popular in massage.  CPTG (Certified Therapeutic Grade) essential oils are roughly 60-70 times more concentrated that the actual plan which they’re derived from.  Therefore, you must dilute the essential oils before using them for massage.  The most popular oils to use for massage are rosemary, lavender, eucalyptus, and sandalwood.

Essential oils opens a whole new world of learning and it’s very exciting to learn the science and history of them.  If you find your curiosity growing, you can even go so far as to study the science of essentials oils in Aromatherapy Education.


What is Aromatherapy?

Aromatherapy takes essential oils that are extracted from plants and uses them for mental, emotional and physical healing.  The oils are dispersed into the air using an aromatherapy diffuser, baths, massage, or palm inhalation.  Aromatherapy is a gentle yet powerful way of healing using CPTG essential oils.  CPTG oils are found naturally in plants and can be extracted from the blossom, bark and wood, leaf, roots, fruit, stem or the resin.

As shown in the video below, the emergency room at Vanderbilt University Medical Center is taking advantage of aromatherapy to improve the stress levels of the hospital staff. This really is a true

Essential Oil Extraction

Essential oils can be used as an effective and natural way to improve a person’s health and promotes physical, mental and emotional well-being.  They help combat stress and boost your immune system.

Essential Oil Distiller

While there are several ways to extract essential oils, steam distillation is the most common.  The parts of the plant are put into a vat which has heated water beneath and the steam from the water rises through the plant and causes the cell walls to break down and release the essence of the plant.  Both the water and the essence and sent through a condenser where they are separated and cooled.  The oil is then taken from the top and water is used as Hydrosol, which is superb for skin care.

Other ways to extract essential oils from plant parts are: cold pressed, carbon dioxide extraction, and solvent extraction.

Adulteration is another aspect that you’ll want to look at closely.  Make sure that you buy your oils from a reputable source that doesn’t dilute or adulterate their oils – this is very common, especially in the lower priced oils.  Melissa essential oil is one of the most common oils to be diluted.  Typically, lower priced bottles of Melissa essential oil are cut with lemon oil to reduce their price since Melissa is so expensive.

Types of Essential Oil Diffusers

Nebulizing Diffusers

The first thing to know about nebulizing diffusers is that they use no water whatsoever, which also means that there is a more concentrated dose of oil in the air.  From a therapeutic standpoint, this is an amazing benefit.  However, from a budget perspective it typically costs more to run a nebulizer than an ultrasonic diffuser.  Also, nebulizers tend to be louder than their counterparts but not so loud that the sound would be noticeable in a mildly noisy household with children in the background.

Ultrasonic Diffusers

Unlike the nebulizers, ultrasonic diffusers use water and a cool mist process to disperse the oil into the surrounding air.  A small ceramic membrane vibrates below the water which is what creates the mist.  No heat is used during this process, so the integrity of the essential oil is maintained.  Ultrasonic diffusers tend to be the favorite due to their overall therapeutic benefit and the fact that they are typically less expensive, cost loss to operate, and make no noise during operation.  These are great diffusers for sleeping because they are so quiet.

Evaporative Diffusers

Evaporative diffusers work by blowing air from within the room through a filter which holds the essential oil and disperses it through the room.  Although this method works well for aromatic reasons, there’s one major drawback:  when essential oils are evaporated, the lighter components of the oil evaporate first and the heavier last resulting in an inconsistent therapeutic value.

Heat Diffusers

Like evaporative diffusers, heat diffusers evaporate the essential oil more quickly but accomplish this using heat.  Some diffusers get hotter to disperse the aroma more quickly, but the best heat diffusers use a much lower level of heat to create more subtle aromas.  The difference between these two temperatures is critical since the hotter diffusers alter the chemical composition of the oil.  Heat diffusers are bought in great abundance due to their low cost and quiet operation but what you gain in these areas is generally lost in therapeutic value.

How can I use Essential Oils?

Wow.  Where do I begin?  Essential oils are commonly used in cleaning and disinfecting, cosmetics, soaps, flavoring of food or drinks, incense, perfumes, medicine, toothpaste, syrups, bath salts, mouthwash, skin cream, and household cleaning products just to name a few.

Essential oils have been used medicinally for ages.  Claims from those who sell oils range from remedies for anything from a rash to cancer.  We have personally seen some wonderful results from essential oils in successfully treating cysts, headaches, rashes and much, much more.


Do essential oils burn when you put them on your skin?

Simply put, yes, some do burn.  Don’t let that scare you.  For those that do tend to be “hot”, which is what you call an oil that burns the skin, it’s important to use what is known as a carrier oil.  Carrier oils are there to dilute the Essential Oil, yet not reduce the effectiveness.


What essential oils are considered to be ‘Hot’?

Essential can cause skin irritation or can have a burning sensation.  Oils that cause this sensation are considered to be ‘hot’ and must be diluted with a carrier oil when used.  Oils that are commonly known as hot are (not all hot oils are listed here):

What are carrier oils?

Carrier oils, which are extracted from the fatty portion of a plant (nuts, seeds, etc), are essentially a vegetable oil.  Carrier oils are used to eliminate the skin irritation caused by Essential Oils.

Carrier oils  include: Jojoba oil (our personal favorite), olive oil, sunflower oil, sweet almond oil (popular), avocado oil, grapeseed oil (popular), and many others. Carrier oils are also commonly used by massage therapists but should also be kept on-hand by anyone using Essential Oils at home.

Do not miss the Carrier Oil Selection Guide I created to make it easy to determine which carrier oil is best for you.


What are infused oils?

Infused oils are plant-based or vegetable oil which has been infused with a flavor of a different oil.  This is commonly done by adding essential oils to the base, or by adding the leaves, stems, roots, flowers of the plant.  Infused oil are much less expensive than essential oils simply because they don’t require much essential oil, which is the harder of the two to extract.  If you are preparing to buy an essential oil and find it much less expensive than normal, be aware that you are likely looking at an infused oil with a very small amount of essential oil added.


Can I use essential oils on my children or the elderly?

Yes, essential oils can be used with all ages.  However, it is important to be very careful with small children and elderly.  Keep the lids tight on your Essential Oils and out of the reach of children.  In the event that the aroma of the Essential Oil is too strong or there is a skin irritation with your child, dilute the oil further with your carrier oil.

Here is a standard guide to use for the dilution of Essential Oils:

Adults ~15 drops Essential Oil in 1 ounce carrier oil

Children age 18 ~ 10 drops Essential Oil in 1 ounce carrier oil

Children age 10-18 ~ 6-9 drops Essential Oil in 1 ounce carrier oil

5-10 years age ~ 5 drops Essential Oil in 1 ounce carrier oil

4 year age, elderly & infirm ~ 4 drops Essential Oil in 1 ounce carrier oil

3 year age ~ 3 drops Essential Oil in 1 ounce carrier oil

2 year age ~ 2 drops Essential Oil in 1 ounce carrier oil

Newborn – 2 years age ~ 1 drop Essential Oil in 1 ounce carrier oil

Can I use essential oils when I’m pregnant?

Caution must be used when pregnant and considering essential oils.  Certain oils can have unwanted effects on a pregnancy, such as rosemary oil, which can cause contractions; and rose oil which can cause uterine bleeding.  Please be sure to consult a doctor or midwife before using any essential oils.  If you have high risk factors during pregnancy, it is advisable to avoid essential oils altogether during this time.

What is the most versatile essential oil?

Without a doubt, tea tree oil is the most versatile oil there is.  We explain this in great detail on the Tea Tree Oil Uses page.
