Over the last few years, more and more people have been turning to cannabidiol — aka CBD — as a part of their health and wellness routine, and it’s easy to see why. Research shows that CBD offers an impressive list of potential health benefits. It can help address issues like pain, depression, anxiety, and sleep disorders, which makes it easy to understand why CBD products are becoming so popular across the United States.
Essential oils are also incredibly popular — with essential oil remedies being shared across the internet — so you might find yourself wondering if you can combine these products, whether or not using CBD and essential oils is safe, and how to try it out for yourself.
What is CBD? How does it work?
CBD, also known as cannabidiol, is one of the main active ingredients found in the cannabis plant. Unlike cannabis, which contains tetrahydrocannabinol (THC), CBD is non-psychoactive — meaning it doesn’t cause the “high” feeling typically associated with cannabis use. Plus, CBD is relatively well-tolerated by most people and it has very few side effects, meaning it’s pretty low risk and isn’t associated with potential abuse.
As far as how it works? Researchers are still figuring that out.
“We are still learning how exactly CBD works. It appears CBD interacts with a wide variety of systems in your body, such as your serotonin system,” explains Dr. Jeff Chen, founder of the UCLA Cannabis Research Initiative and CEO and CoFounder of Radicle Science. “CBD also interacts with your endocannabinoid system, which is spread throughout your entire body. Whereas THC exerts its effects by directly binding to your cannabinoid receptors, CBD doesn’t bind to cannabinoid receptors, but instead appears to slow the breakdown of the endocannabinoids your own body naturally produces.”
Translation? While we don’t know how CBD works with our endocannabinoid system (ECS) and cannabinoid receptors, we do know that the ECS plays a role in bodily functions like sleep, memory, and mood — as well as maintaining our bodies’ homeostasis, AKA the balance and stability of our bodies’ systems.
From there, many believe that CBD works by helping your body return to that state of homeostasis — so if your body needs sleep, CBD might help with that. If you need to boost your energy, it might help with that too. And because cannabinoid receptors within the ECS are located throughout your body, although there’s a higher concentration of these receptors in your brain, that’s why CBD offers such a wide range of potential benefits.
What about essential oils? Do they work?

Essential oils have been used throughout human history, but before we dive into the science, it’s important to highlight that not all essential oils are safe to consume orally and others can cause damage if they’re applied directly to your skin. Unlike CBD oil, different essential oils vary wildly — and some carry severe health risks if used incorrectly — so you’ll want to do extensive research prior to combining these and you’ll want to consult your primary care doctor.
That being said, when it comes to using essential oils (and deciding whether or not they work), the answer is “it depends.” Different oils offer different benefits, and not all essential oils have been extensively studied. You’ll want to speak with a medical expert before using any essential oils to make sure you’re using them safely.
Is it safe to mix CBD and essential oils?
Because CBD and essential oils use in humans haven’t been studied extensively, it’s hard to give a clear answer on whether or not it’s safe to mix the two. Especially when you’re looking at something like essential oils — where some are considered harmless for both oral and topical use while others can be poisonous — it’s important to act with an abundance of caution.
“Most herbalists and Traditional Chinese Medicine practitioners usually recommend using multiple botanicals to treat a condition. Rarely, do they ever recommend a single herb,” explains Dr. Felecia Dawson, a physician and cannabis advocate.” Thus, adding additional terpenes via essential oils may give better results. I would recommend working with someone knowledgeable about CBD and essential oils to stay safe, save money and time.
So even though CBD itself might be relatively low risk — and there might be some benefits from mixing CBD and essential oils — the safety of essential oils varies wildly on the specific oil you’re using and the method of delivery. If you’re not sure about mixing the two then it might be worth keeping these two habits separate, or speaking with a medical professional, at least until we know more.

If you’ve ever used a CBD oil, you’ve gotten more from the product than just cannabidiol (CBD). For multiple reasons, manufacturers include a carrier oil, too.
As its name suggests, a carrier oil delivers (or carries) the contents of the active compound. In this case, it’s CBD. In the realm of beauty products, carrier oils dilute essential oils because the essential oil may be too strong on its own. (For example, a lavender reaction from lavender oil can cause the skin to itch, burn, or break out in blisters.)
Carrier oils are important to CBD because they help dissolve the cannabinoid’s molecules so they can be absorbed by the body. Many carrier oils are similar, but they may have differences that could be important to you for various reasons. For example, most of them are nut-based or plant-based, and you could be allergic to them. Oils that are taken orally may not taste good to you. Reading the label is a smart move—as long as you know what you’re looking for.
This article explains the purpose of carrier oils and the possible side effects. It also describes the six carrier oils you’re likely to see in stores and online, including their advantages and drawbacks.
Marketing Outpaces Science
CBD is an abbreviation for cannabidiol. It’s one of 100-plus chemicals in the cannabis plant that may have health benefits. It’s widely assumed that CBD oil can relieve arthritis pain, chronic pain, and chronic nerve pain as well as reduce inflammation, ease anxiety, and improve sleep. Researchers are actively studying other uses for CBD oil, particularly in terms of slowing cancer cell growth.
Purpose of CBD Carrier Oils
CBD products use different carrier oils, sometimes alone and sometimes in combinations. They serve several important functions:
One key reason for using a carrier oil is that it improves bioavailability, which means it helps your body absorb CBD oil. CBD is fat-soluble, which means that it dissolves in oil rather than water. Fat-soluble substances are better absorbed when digested along with fat, even in small amounts.
When you digest water-soluble substances, like sugar or many vitamins and minerals, your digestive tract sends them directly into your bloodstream (because blood is a water-based liquid).
Fat-soluble substances can’t be absorbed this way. Instead, your digestive tract sends them into fatty tissues and they’re distributed through your body by the lymphatic system, which is part of your immune system. Any excess is stored in your liver and fatty tissues for later use.
All carrier oils are fat-soluble, which means CBD dissolves in it. Then the oil carries the CBD into the proper tissues so they’re more accessible by your body.
Know Your Tinctures
CBD products have introduced consumers to a new lexicon. For example, concentrated CBD oil usually taken through a dropper is known as a tincture.
CBD is a potent chemical, which means you don’t need much of it for a medicinal effect. However, this poses a problem when it comes to dosing. To deliver accurate and consistent doses, it’s easier to measure out a dropperful of CBD-infused oil than a tiny amount of crystalline isolate (which is CBD in pure form).
Added Health Benefits
Carrier oils sometimes include health benefits all on their own. For example, olive oil has gotten a lot of attention for its heart-healthy benefits.
If there’s an oil you’d like to get more of in your diet, adding it to your CBD regimen is one way to get it. (This said, it remains debatable whether one or two droppers of carrier oil a day is enough to have any tangible effect on your health. This is another CBD-related topic that falls under the category of “more research is required.”)
CBD Products Come From Hemp
CBD products almost always are derived from hemp, which is botanically and legally different from the marijuana plant. By law, CBD products can’t contain more than 0.3% THC (short for delta-9- tetrahydrocannabinol ), which is the chemical in marijuana that creates a high.
Side Effects and Precautions
Most people don’t have side effects from common carrier oils. Some oils, though, may not be right for people with certain illnesses or who take certain medications. Always check with your healthcare provider before adding anything to your dietary regimen—even a “natural” product like CBD in a carrier oil. Natural doesn’t always mean safe.
If you have tree-nut allergies or other food allergies, be especially diligent about selecting CBD products with carrier oils you know are safe for you. All ingredients should be specified on the label.
For topical preparations, know that some carrier oils or other added ingredients may cause an itchy, red rash called allergic contact dermatitis. Others may cause a skin reaction after sun exposure. Be sure you’re familiar with the potential side effects of whatever products you’re using. And play it safe by testing a miniscule amount of topical oil on an obscure patch of skin to see if you develop a reaction.
What About Essential Oils?
Carrier oils aren’t the same thing as essential oils used for aromatherapy. Essential oils are highly concentrated, which is why they have a strong fragrance. Many essential oils can cause poisoning when ingested or absorbed through the skin, even in small amounts. This is true even if the oil comes from something that is normally safe to ingest, such as nutmeg.
Essential oils are often used topically (on the skin) after being diluted by a carrier oil. Essential oils themselves, however, should never be used as a carrier oil. Some topical CBD formulations may include essential oils such as lavender or eucalyptus oils because of their purported health benefits.
Before using these products, be sure you’re familiar with the ingredients and that you’re not allergic to any of them. Watch also for side effects, which can occur soon after using them.
Common Carrier Oils
Some CBD oils may contain one or more carrier oils. Some common carrier oils are:
- Medium-chain triglyceride (MCT) oil
- Hemp seed oil
- Olive oil
- Avocado oil
MCT oil is the most common carrier oil for CBD products. It can be derived from coconut or palm kernel oil, but coconut is the most common source. On labels, it’s sometimes listed as fractionated coconut oil, which means it contains more liquid than solid compared to normal coconut oil, thanks to fatty acids.
Medium-chain triglycerides are a type of fatty acid that your body can quickly absorb because it doesn’t have to break it down via digestion before sending it off to the lymph system. It also absorbs easily through the skin.
Long-chain triglycerides require more digestion time. Short-chain triglycerides are often consumed by gut bacteria before they’ve had time to be absorbed. So MCTs are the most useful.
- Quick absorption due to molecular structure
- 90% saturated fat, which also aids absorption
- Light, thin oil
- Almost flavorless
- Doesn’t require chemical processing
- Less expensive than some carrier oils
- Slow to break down and go rancid
- Temporary digestive side effects (nausea, gas, diarrhea, vomiting) in some people
- Possible excessive build-up of ketones in the body (dangerous with poorly controlled diabetes)
- Not recommended for people with liver disease
- May interact with cholesterol-lowering statin drugs
Additional Health Claims
Some scientific evidence suggests that MCT oil may:
- Help with weight loss by reducing your appetite, increasing metabolism, and making your body burn calories faster
- Have benefits for people with autism, epilepsy, cancer, type 2 diabetes, and Alzheimer’s disease
- Activate the immune system to fight yeast and bacterial overgrowth
While promising, much of this research is preliminary. More research is needed before MCT oil can be recommended for these uses.
Scrutinize Coconut Oil Labels
If the label of a CBD product says “coconut oil,” it’s likely regular coconut oil and not MCT. While perfectly fine as a carrier oil, regular coconut oil may not have all of the same benefits of an MCT.
Hemp Seed Oil
It may come from the same plant, but hemp seed oil (sometimes called hemp oil) and CBD oil aren’t the same thing. CBD comes from the flower while hemp seed oil comes from the seeds. The seeds contain fewer beneficial chemicals (cannabinoids and terpenes) than the flower and in much lower concentrations. However, they do contain some hemp phytochemicals that aren’t present in the flowers.
Using hemp seed oil as a carrier oil for CBD may contribute to what’s called the “entourage effect,” which basically means that combining parts of the plant may make each component more effective than it would be alone.
This quality makes hemp seed oil a popular choice for “full-spectrum” products, which contain all of the component chemicals of the hemp plant rather than just CBD.
- Rich in omega-3 fatty acids, which may lower inflammation
- Ideal ratio of omega-3 to omega-6 fatty acids
- High antioxidant levels
- Good source of fiber
- Contains magnesium, calcium, iron, and zinc
- Possible entourage effect
- Lower solvency than MCT oil, meaning it can’t hold as much CBD
- Higher priced than MCT oil
- Flavor (sometimes described as “sharp” or “herby”) may clash with some palates
- Side effects may include diarrhea, nausea, throat irritation, slow heart rate, high blood pressure
Some companies try to pass off hemp seed oil as CBD oil. Be sure to check the ingredients and amount of CBD a product contains before you buy it. All reputable companies should provide this information on their labels and websites.
Additional Health Claims
Hemp seed has been used medicinally for a wide array of conditions, most of which have not been researched enough to say for sure whether they’re safe and effective. The conditions include:
, for its anti-inflammatory properties and blood pressure and other conditions involving skin inflammation
Olive oil is probably the carrier oil you’re most familiar with. It’s certainly the best researched. It’s become one of the most commonly used cooking oils because of its many well-established health benefits:
- High in iron, vitamin K, vitamin E
- Rich in antioxidants
- Highly trusted
- Absorbed by the skin even faster than MCT
- Its long-chain triglycerides are slower to absorb than MCT (but may absorb more efficiently)
- Lower solvency than MCT, meaning it can’t hold as much CBD
- Thicker than most other carrier oils, which may be unpleasant
- Flavor is relatively strong and may be distasteful to some people
Additional Health Claims
Thanks to a significant amount of research, olive oil is known to:
- Boost immunity
- Reduce inflammation
- Increase good cholesterol and lower bad cholesterol
- Prevent blood platelet clumping, which can cause heart attacks
- Aid in blood clotting
- Improve gut-bacteria balance
- Support proper nerve function
- Prevent cognitive decline
- Protect bones from thinning (osteoporosis)
Avocado oil has become more popular for a variety of uses, including cooking, as researchers have learned about its health benefits. As a CBD carrier oil, it’s used most often in topical products, but you can also find it in products that are meant to be ingested.
- Quickly and easily absorbed by your skin and digestive tract
- Nutty flavor may be more pleasant than some alternatives
- Especially good for topical uses
- Rich in antioxidants
- High in vitamins A, B, D, and E
- Much thicker than most carrier oils, which may be unpleasant
- Significantly more expensive than many carrier oils
- Higher allergy risk than many carrier oils
Additional Health Claims
Most of the research into avocado oil has been performed on animals, not people. Until researchers take this next step, preliminary evidence suggests that avocado oil may:
- Lower bad cholesterol and raise good cholesterol, which decreases the risk of heart disease
- Improve glucose tolerance and reduce insulin resistance, providing protection from diabetes
- Improve metabolic markers
Avocado oil is less likely than many oils to clog your pores, so it’s popular for topical use. Plus, its slow drying time may help it last longer than some topical preparations.
Avocado allergies are possible. If you experience itching in your mouth after ingesting avocados or avocado oil, don’t ingest any more before talking with your healthcare provider about it. Some allergies tend to occur together. People with avocado allergies may be especially sensitive to:
- Other fruits and vegetables
If you have an allergic reaction to any of these things, you should be tested for a reaction to the others as well.
Extreme Symptoms Are Possible
Extreme allergy symptoms, such as difficulty breathing or anaphylaxis, are uncommon (but possible) with avocados because digestive enzymes tend to break down the allergen before it’s absorbed into your body. Get emergency medical attention if you experience these symptoms.

A Word From Verywell
Many people are quick to ask: “Which CBD carrier oil is the best?” Now you know that the answer depends on several factors, including the type and uses of the CBD product, whether you have allergies or certain health conditions, and your personal preferences. So look at it this way: If you try one oil and don’t like it, you can always try a different one. Meanwhile, be sure to ask your healthcare provider or pharmacist for advice along the way.
