Internal Use of Essential Oils: Safe and Effective Methods for Wellness

People have used essential oils for centuries for their medicinal and therapeutic properties.

While they are commonly used for aromatherapy and topical application, essential oils can also be used internally to support overall wellness.

Internal use of essential oils involves ingesting them in small amounts to promote physical, emotional, and mental health.

However, it’s important to approach internal use cautiously and know which oils are safe to consume and in what amounts.

In this article, we’ll explore the benefits and potential risks of using essential oils internally and provide safe and effective methods.

Before using essential oils internally, you must make sure your oils are safe for internal use!

The only brand of essential oil I use internally is doTERRA.

DoTERRA makes it easy to discern which oils are safe for internal use and which are not.

If an essential oil is safe for internal use, it will display a nutrition fact label on the back of the bottle, just like any other food product.

If an oil is unsafe for internal use, the nutrient fact label will not be on the bottle.

I cannot speak for the quality of other essential oils because I do not use any other brands.

If you are using other brands of essential oils, please research and ensure your oils are safe for ingestion before taking them internally!

Internal Use of Essential Oils

Learning about each application method will enhance your essential oil experience if you are relatively new to essential oils.

The main application methods for essential oils are known as aromatic use, topical use, and internal use.

Internal usage is one of the most beneficial ways to use essential oils. However, it is also one of the most misunderstood.

While internal usage requires careful application and caution, using essential oils internally to benefit your body and promote overall wellness is still possible.

Today we will discuss some of the best practices for the internal use of essential oils.

Why Use Essential Oils Internally?

While aromatic and topical applications are practical, internal usage offers several benefits that cannot be achieved through topical or aromatic use and can improve your essential oil usage overall.

With exclusive benefits for the body, internal use is crucial to any essential oil experience.

As you learn more about essential oils and start incorporating them into your lifestyle, you will see how beneficial internal usage can be.

Throughout this presentation, we will discuss the benefits of internal usage in greater detail.

Benefits of Internal Use

There are several reasons to use essential oils internally.

Because essential oils hold internal benefits for the body, many people use them for things like:

  • promoting healthy cell function
  • supporting gastrointestinal health
  • maintaining healthy immune function.*

Essential oils provide a safe, natural way to regularly deal with many issues our bodies face.

In addition to wellness benefits, essential oils also hold cleaning properties that can be helpful for the internal cleansing of the body.*

Lastly, essential oils are beneficial for adding natural, potent flavors to your favorite meals and drinks.

Using essential oils in cooking will add powerful flavors to your dishes and allow you to simultaneously experience the internal health benefits essential oils offer.*

Is It Safe to Use Essential Oils Internally?

Because essential oils are so naturally powerful and potent, those new to essential oils often wonder, “Is it really safe for me to use them internally?”

The answer is yes.

Essential oils come from natural compounds, like plants and fruits, so they provide a safe, natural way to experience internal benefits for the body.

Our bodies are already equipped to metabolize and process natural compounds like those found in fruits and plants, so we are prepared to process essential oils.

Remember that due to their chemistry, certain essential oils are never safe for internal consumption (we will talk about those later). However, plenty of essential oils can be safely used internally to benefit the body.

Scientific Background

As mentioned, essential oils hold many internal benefits for the body.

You might wonder, “How does taking essential oils internally provide the body with certain benefits?”

Much like other things we consume, essential oils are processed through the body, metabolized to provide the body with benefits, and then excreted.

Each essential oil has a unique chemical profile, which gives it certain benefits for the body.

When you ingest an essential oil, it is transported through the gastrointestinal tract into the bloodstream, which can then be distributed throughout the rest of the body.

Like other compounds we ingest, our body can only handle essential oils in appropriate amounts.

Now that we have discussed why we want to use essential oils internally and how internal usage interacts with the body, let’s review some of the necessary safety guidelines to help us safely use essential oils internally.

Safety Guidelines

There is a lot to consider when it comes to internal usage.

First, consider your health status, history, and conditions before using essential oils internally.

If you have any special conditions or concerns regarding how essential oils might affect your current health status, it is always a good idea to consult with your physician before using essential oils internally.

After considering your health status, you must also practice taking appropriate amounts, consider sensitivity, and be aware of potential toxicity. We will discuss each of these areas in more detail.

As mentioned, some essential oils are never safe for internal use.

Never ingest the following oils:

  • Arborvitae
  • Cedarwood
  • Cypress
  • Douglas Fir
  • Eucalyptus
  • Spikenard
  • White Fir
  • Wintergreen

Internal Dosing and Dilution

The key to safe internal usage is to always pay attention to the amount you take.

The appropriate amount will depend on:

  • individual health status
  • age
  • size
  • the particular oil that you are using

However, a few general guidelines will help you stay within the parameters of safe use.

When using essential oils internally, starting with the smallest possible amount is always a good idea: one to two drops.

This will allow you to see how the oil interacts with your body, and you can always increase the amount as needed once you see how your body reacts.

Again, it depends on the particular oil you are using, but the typical recommended amount for internal usage is one to five drops.

Beyond this point, increasing the amount will no longer add benefit, and taking too much can be potentially harmful.

Instead of increasing the amount, taking smaller daily amounts is better, repeating every four to six hours as needed.

It is typically recommended that the user doesn’t exceed 20 drops of essential oils internally within a 24-hour time period.

It is best to stick with lower amounts when using an essential oil daily over an extended period.

Dilution: Some essential oils must always be diluted before being used internally because of their strong chemical makeup and how they can affect the body.

Make sure to always dilute:

  • Cassia
  • Cinnamon
  • Clove
  • Cumin
  • Oregano
  • Thyme

Dilute these essential oils in at least four ounces of liquid before taking them internally.

You can also dilute these oils by adding one to two drops to a recipe or beverage before consuming.

(Note: these essential oils do not need to be diluted if taken using capsules.)


Because each essential oil has a different chemical makeup, and each person has a different health status and sensitivity, it is essential to consider the internal use of oils on an oil-by-oil basis.

First, it is important to note that essential oils cannot cause allergic reactions.

Allergic reactions happen when our bodies are exposed to protein molecules that cause us to experience an abnormal immune reaction.

Because essential oils are made up of volatile aromatic compounds, they do not contain any protein molecules and cannot cause a genuine allergic reaction.

Although essential oils cannot cause an allergic reaction, they can still cause a sensitivity reaction.

The symptoms associated with sensitivity reactions are often similar to those during an allergic reaction.

So, how do you know if you are sensitive to a particular oil?

If you are sensitive to a particular oil, you might notice sensitivity responses in areas like the skin, respiratory system, or digestive system.

You might also experience pain, swelling, or tenderness in the skin, skin irritations, stomach upset, or difficulty breathing.

Any of these reactions could mean your body is sensitive to that oil.

When you experience sensitivity after using an essential oil internally, you must adjust your application methods to avoid irritation.

Because a sensitivity reaction isn’t the same as an allergic reaction, it might still be possible to use the essential oil if you change your application method.

For example, if you have a sensitivity response to an essential oil after using it internally, you might still be able to use it topically or aromatically.

You can also adjust the amount to see if that caused the sensitivity.

Diluting an oil or using it in a smaller amount might help to reduce the sensitivity.

Remember that if you ever experience sensitivity in the digestive system after using an essential oil, you should immediately stop using it.

If you only use a small amount of essential oil, you can subside the discomfort by drinking fluids.

If you consume a large amount of oil, it is best to contact poison control.

When using essential oils internally, if you ever experience a sensitivity reaction that becomes severe or prolonged, you should seek medical attention to ensure your safety.


As mentioned, you can feel safe using essential oils internally if you observe the proper recommend amounts.

In extreme cases, essential oils can cause toxicity if the recommended amounts are exceeded.

Toxicity refers to the point at which a substance becomes damaging or harmful to the body.

Remember, any substance, even seemingly harmless things like water, vitamins, or minerals, can be toxic to the body when consumed in incorrect amounts.

Like anything else you would put in your body, safely using essential oils is all about sticking to the proper recommended amounts.

The user must far exceed the recommended amount for an essential oil to reach the toxic range.

Using Essential Oils Internally

Now that we have discussed some safety guidelines for using essential oils internally, let’s discuss how the internal application works.

Several internal application methods are easy for essential oil beginners and practical enough for the most seasoned essential oil user.

Here are some of the most basic application methods for internal usage:

Adding a drop or two of essential oil to your glass of water is a simple way to enjoy its internal benefits.

Aside from being one of the easiest ways to use essential oils internally, this can add extra flavor to plain water.

Supplement capsules provide another easy way to take essential oils internally.

All you have to do is add a few drops of the essential oil into the supplement capsule and swallow.

dōTERRA sells vegetarian supplement capsules that don’t contain animal products or preservatives and are accessible for the body to digest.

You can also take essential oils directly by swallowing them on or under the tongue.

Just remember that essential oils are very potent, and even a tiny drop on the tongue can be very powerful.

Also, please remember that some essential oils should always be diluted before internal usage. Oils like Cassia, Cinnamon, Clove, Cumin, Oregano, and Thyme should be diluted in at least four ounces of water before swallowing.

However, diluting these oils before adding them to a veggie capsule is unnecessary.

One of the most creative ways to enjoy the internal benefits of essential oils is through cooking and baking.

It is easy to add essential oils to your favorite recipes, and not only will it enhance the flavor of your dish, but it will also allow you to experience the internal benefits of the oil.

Essential oils can easily be added to your favorite entrees, baked goods, desserts, meat marinades, salsas and dips, beverages, and more.
