CBD oil, or cannabidiol, is a natural compound found in marijuana and another related plant, hemp. Unlike THC, another compound in the marijuana plant, CBD doesn’t cause a “high.” However, it may help reduce nausea and other unpleasant symptoms, like pain and anxiety. If you have nausea due to a medical condition or a medication you’re taking, such as chemotherapy drugs, talk to your doctor about using CBD to get relief.

Cannabidiol (CBD) is growing increasingly popular, thanks to its many purported health benefits and non-intoxicating properties (most CBD products contain less than 0.3% tetrahydrocannabinol, or THC). In fact, 60% of U.S. adults have tried CBD at some point and believe it has medicinal benefits, according to a recent Forbes Health survey of 2,000 U.S. adults conducted by OnePoll. As research evolves and sheds light on CBD’s efficacy, especially for pain relief, more and more people are adding it to their daily wellness regimens.
Consumers can choose from a variety of CBD products, from oils to gummies to vapes to capsules. But figuring out the safe and effective CBD dose for an individual is a complex decision.

Here’s how to find the right CBD dosage for you and how to consume it safely.
Determining the Best CBD Dosage for You
With the exception of one CBD product, a prescription drug used to treat seizures associated with particular syndromes, the Food and Drug Administration (FDA) doesn’t regulate the use of CBD. (In fact, it’s illegal to market CBD as a supplement or add it to food.) Therefore, it’s best to consult a doctor with experience in CBD administration to determine your ideal dosage.
Expressed in milligrams (mg), CBD dosage largely depends on the conditions and symptoms you’re trying to treat and your unique endocannabinoid system, which is associated with motor control, behavior, emotions, the nervous system and homeostasis. CBD dosage remains an area of active research—more large, high-quality studies are needed in different populations to determine appropriate dosing, efficacy and safety guidelines.
“It’s best to start small and gradually increase your dose up to a level that gives you the desired effect,” says Cheryl Bugailiskis, M.D., a cannabis specialist at Heally, a telehealth platform for alternative medicine. Your starting point might look like half a CBD gummy or a drop of oil. Ideally, navigate this process under the guidance of a qualified physician.
If you’re still not sure where to start, mydosage.com offers a questionnaire and CBD calculator to help you based on your specific symptoms and usage goals.
How to Calculate CBD Dosage
When you consume CBD gummies, capsules or softgels, dosage is typically expressed per unit. For example, there may be 50 milligrams of CBD in each individual gummy. These products don’t offer much dosage flexibility since you can’t split up capsules easily. For instance, if one softgel capsule didn’t provide your desired result, you would have to take another full capsule, doubling the total dose.
CBD oil, on the other hand, makes it easier, to begin with a small dose. But calculating CBD oil dosage can be less straightforward. Oils and tinctures tend to come in a dropper bottle and, typically, only the total liquid volume and CBD contents are listed on the label. For example, the label might simply state there’s 1,500 milligrams of CBD in the 30-milliliter bottle.
But what does 1 milliliter look like? Due to the current lack of regulation of CBD, this calculation can be tricky. Start by figuring out the volume of a single drop in your dropper, which is usually 0.05 milliliters, according to Dr. Bugailiskis. If you’re unsure, ask the company.
Here’s where math comes in. Let’s continue with the 30-milliliter bottle with 1,500 milligrams of CBD and 0.05 milliliters in a single drop as our example.
1500mg÷30mL = 50 mg/mL
This bottle contains 50 milligrams of CBD per milliliter. Let’s see how many milligrams are in a drop:
50mg/mL ×0.05mL/drop = 2.5mg/drop
Each drop contains 2.5 milligrams of CBD.
Next, you can calculate how many drops you need to reach your goal dosage. Let’s say you want to consume 25 milligrams each day.
25mg÷2.5mg/drop = 10 drops
10 drops ×2.5mg = 0.5mL
With this CBD oil dosage calculator as your guide, you would find that you needed to consume 10 drops, or 0.5 milliliters, to reach 25 milligrams. And if you intend to consume 25 milligrams daily, you can expect this particular bottle to serve as a 60-day supply.
Some CBD products do some of this math for you and illustrate how many milligrams are in a milliliter, some even marking these points on the dropper so you know exactly what you’re taking.
CBD Dosage for Different Ailments
Without FDA approval, there is little guidance in the U.S. on how much CBD a person should consume for various conditions.
In many medical studies on CBD, you see administered doses reach hundreds of milligrams a day, which sounds severe compared to our starting dosage example of 25 milligrams. However, Steven Phan, founder of Come Back Daily, a CBD dispensary in New York, points out that patients in these studies are often dealing with serious flare-ups and pain-inducing conditions compared to everyday dispensary customers.
Below are clinically-studied CBD dosages based on different ailments and conditions. Note: Some of the formulations studied contained THC as well—not all available dosage research sticks strictly to CBD.
*Dosages are based solely on small, short-term clinical study results where CBD proved significantly successful over placebo. Much larger studies are needed to further strengthen the evidence.
FDA-approved Epidiolex administers CBD orally as a liquid to treat seizures associated with Lennox-Gastaut syndrome, Dravet syndrome and tuberous sclerosis complex. The dosage of Epidiolex is determined by taking the patient’s weight in kilograms (kg) into account.
Several countries, including Canada and those in the U.K., have approved the use of Sativex, an oral spray with equal amounts of CBD and THC, to treat pain stemming from multiple sclerosis. Canada has also approved it for treatment of cancer pain.
The medical and research community still has a long way to go before figuring out what dose works best for each condition. At an individual level, consumers can experiment with caution until they find what works best for them.

How to Take CBD
Popular ways to take CBD include:
- Oils and tinctures (extracts of plant material dissolved in ethanol): A liquid that comes in a bottle with a dropper
- Gummies: A soft, chewable candy that’s often fruit-flavored
- Sprays: A liquid that comes in a bottle with a nozzle for spraying into the mouth
- Capsules: Tablets or softgels that are ingested by mouth
- Vapes: CBD oil that’s heated without ignition, resulting in an inhalable vapor
- Flower: Dried hemp plant that’s often ignited and smoked
- Edibles: Any food that CBD oil has been added to, such as brownies or chips
- Drinks: Any beverage that’s infused with CBD, often in the form of hemp extract
Your CBD product of choice will largely depend on your personal preferences, as well as your budget since prices vary depending on the potency of ingredients and manufacturing processes. Different mediums also offer varying levels of bioavailability—or how much of what you take is actually absorbed into your bloodstream to have an effect. For example, if you ingest 10 milligrams of CBD via 1 milliliter of liquid, your body might absorb about 60% of it, or about 6 milligrams.
Cannabinoids generally have a low bioavailability compared to other substances, according to Jordan Tishler, M.D., a physician specializing in cannabis treatment in Massachusetts. However, “products that contain emulsifiers like egg yolk (brownies) or lecithin (some gummies) do better,” he says.
With that said, ingesting CBD via gummies or other edibles may take longer to take effect since the CBD has to travel to your digestive system to be broken down and absorbed.
Can You Take Too Much CBD?
Like with any substance, you can take more CBD than your body can handle. Studies show doses up to 1,500 milligrams a day have been well-tolerated, but every person is different  Bergamaschi MM, Costa Queiroz RH, Zuardi AW, Crippa JAS. Safety and side effects of cannabidiol, a Cannabis sativa constituent. Current Drug Safety. 2011;6(4):237-49. . Ingesting too much CBD can cause unpleasant side effects, such as dry mouth, nausea, diarrhea, upset stomach, drowsiness, lightheadedness and general disorientation. While rare, liver damage can also occur.
What’s more, CBD can have serious interactions with certain medications. In evaluating available information on five prescription CBD-based medications, researchers found 139 medications could have a potential drug-drug interaction with CBD  Kocis PT, Vrana KE. Delta-9-Tetrahydrocannabinol and Cannabidiol Drug-Drug Interactions. Medical Cannabis and Cannabinoids. 2020;3:61–73. . People who take certain blood thinners, heart rhythm medications, thyroid medications and seizure medications need to be particularly careful.
At the end of the day, not all supplements are created equal, which is why it’s important to work alongside a health care provider when adding CBD to your wellness regimen and research reliable brands. And while emerging research and anecdotal evidence is promising, more large, randomized-controlled trials are needed to further understand the benefits of CBD and its dosing.

CBD or Cannabidiol is one of the 100+ cannabinoids that can be found in cannabis, which contains hemp and marijuana. CBD has been shown to have multiple health benefits for people with different conditions such as anxiety, pain, and even nausea.
5 Best CBD Oils for Nausea
What is Nausea?
Nausea occurs when you feel a sensation in the back of your throat, a sudden urge to vomit, and a feeling of uneasiness. Nausea can be triggered by an unpleasant odor, upset stomach, or even flashing lights at the disco. If you are pregnant, nausea is common around 6 weeks since it occurs during implantation.
Nausea is not a very dangerous condition, but it can be extremely uncomfortable. It is usually caused by an underlying disease or medical disorder. Nausea is one of the most common symptoms of pregnancy.
What causes nausea?
There are many reasons. Some include:
· Diseases of the digestive system such as food poisoning or a peptic ulcer.
· Problems with the inner ear, nose, throat, and stomach.
· Migraine headaches that are accompanied by symptoms like nausea and vomiting.
· Head injuries or concussions.
· High blood pressure.
· Severe anxiety or stress.
How can CBD Oil help?
There has been scientific research that suggests that not only does CBD reduce nausea, but it may also be able to reduce vomiting and the urge to vomit. The following is a list of conditions where CBD oil has been observed as beneficial:
· Nausea associated with chemo, radiation therapy, and headache.
· Vomiting associated with AIDS/HIV treatments.
· Anxiety disorders such as panic disorder, post-traumatic stress disorder (PTSD), social anxiety disorder (SAD), obsessive-compulsive disorder (OCD), depression, general anxiety disorder (GAD).
· Multiple sclerosis (MS).
Of course, you should always consult your doctor before adding CBD to any health regimen or routine.
What is CBD?
CBD, also known as Cannabidiol, is a chemical compound that comes from the hemp or marijuana plant. It contains less than 0.3% THC which means it does not produce psychoactive effects like those produced by THC. The human body has an endocannabinoid system that interacts with CBD to create balance in the body.
Are there any side effects of using CBD Oil for Nausea?
There have been no side effects reported from using CBD to treat nausea. In fact, several studies have found that it has a positive effect on reducing both vomiting and nausea.
The most commonly reported CBD side effects include:
· Low blood pressure.
The side effects of CBD are usually very mild. Some people have also experienced red eyes when using CBD in the form of e-liquid.
The criteria we used to determine the best CBD oils for nausea includes:
We only included those companies that met our requirements and had a proven track record of positive customer feedback and a strong reputation within the online community.
Customer feedback was given the highest priority in this category because it is the best way to determine how well a company is doing when it comes to customer service and product satisfaction.
We also wanted to ensure that these companies were well-established within the online community so they had a proven track record of providing high-quality products and services.
We also gave priority to those companies that had a strong reputation within the online community by regularly engaging with their customers and any questions or concerns they may have about their products.
Price, discounts, and specials.
It’s always nice when you can get a discount or special offer. We gave priority to those CBD products that offered a discount, sale, or special promotion whether it was for first-time buyers and/or returning customers.
We also placed a key factor on the companies that provided exceptional customer service and had reliable contact methods such as live chat, email support, FAQ’s, product FAQ’s, educational materials, and online tools.
As with any food or nutritional supplement, we want to ensure that what you’re ingesting is completely safe and of the highest quality. That’s why we prioritized the companies that had organic certification by a third-party organization.
Potency of CBD used.
We made sure that the CBD products offered by these companies had a high uptake rate. We also wanted to ensure that they were full-spectrum, which means they weren’t isolated or refined to only contain CBD but also contained other cannabinoids and terpenes including CBDA, CBCA, THC, CBG, and so on.
Price to value ratio.
We wanted to ensure that these CBD companies not only met our criteria but also provided products at a fair and reasonable price when compared with the competition.
How well the product worked for its intended use case.
We wanted to ensure that any product we recommended would be effective not only for its intended use but also safe and effective for your individual needs.

How to store the best CBD oils for nausea?
One of the critical things to consider when storing CBD oil is that it needs to be properly sealed. If you do not, then moisture could enter into your product which can cause mold or bacteria to grow in your CBD oil. Once this happens, it won’t matter how well you seal your bottle because the oil has already been contaminated.
You should also avoid exposure to light which can cause your CBD oil to lose some of its efficacy. To keep it fresh, store it in a dark, cool cabinet or drawer away from sunlight.
Why does CBD work for nausea?
There are two explanations for why CBD could help with nausea. The first is that it interacts with the serotonin receptors in your body which can affect your perception or feelings about what you’re experiencing.
The second explanation is that CBD inhibits the growth of new cells in your stomach lining to reduce the frequency and severity of symptoms like vomiting and nausea.
Will CBD oils for nausea get me high?
No. While CBD has many of the same qualities as cannabis, it doesn’t contain the psychoactive compound THC. This means that you won’t feel high when taking CBD oil for nausea.
Do I need special CBD oil for nausea?
While most CBD oils are great for combating various types of chronic pain or anxiety, not all of them work well with vomiting and nausea. This is why it’s important to pick the right product that will meet your specific needs.
Is CBD oil legal?
CBD oil is legal in most places throughout the United States. With that being said, you should check your local laws before purchasing any CBD products.
What are other side effects of CBD oil?
Some people have experienced dry mouth or drowsiness when taking CBD because it interacts with receptors throughout your body. In most cases, these side effects will dissipate after taking CBD for a few weeks.
Are there any other ways to take CBD oil?
Besides swallowing a gummy or dropper full of CBD oil, you can also add it to food and drink. While the supplements have an unpleasant taste on their own, you can mask the taste by mixing the oil with honey, putting it in coffee or tea, or adding it to food.
What does CBD feel like?
Because CBD doesn’t contain THC (the psychoactive compound found in cannabis), you will not feel high when taking CBD. That said, there are reports of reduced anxiety and relaxation which could alter your perception, behavior, and how you feel.
What’s the difference between CBD and cannabis?
CBD is a compound found in cannabis. It can also be extracted from hemp and then sold as a supplement. The reason why CBD and cannabis are both classified as “hemp extracts” is because they share similar qualities like low toxicity and not causing a psychoactive high.
What other factors should I consider when buying CBD for nausea?
There are several factors that you should consider when buying CBD for nausea. Here are some of the most important questions to think about:
What is the source of CBD oil?
Look for a high-quality product made from organic hemp plants instead of marijuana plants. This will ensure that your CBD is free of heavy metals, pesticides, and other toxins.
What is the CBD to THC ratio of the product?
In general, it’s best to look for a product with as much CBD as possible and negligible amounts of THC. The higher the amount of CBD compared to THC, the more likely you’ll be to experience all of its health benefits without feeling high or experiencing negative side effects like anxiety and paranoia.
What is the concentration of CBD per milliliter?
The more milligrams of CBD that your product contains, the higher its potency and effects will be on your body. Look for a product that has at least 20 mg to 50 mg of CBD per milliliter.
How many milliliters are in the bottle?
Remember that the effects of CBD increase with concentration. If you buy a product with only 10 ml, it won’t last very long and you’ll likely have to re-purchase more frequently which can get costly.
What is the ideal serving size for my needs?
If you are new to CBD or if you don’t know what dose to use, start low and go slow. Start with one milliliter of the product and see how it affects you after 30 minutes. Consider using another milliliter if needed (but do not exceed eight milliliters in a 24-hour period).
How do I get CBD into my system?
There are several ways to get CBD into your system. The options include tinctures, edibles like gummies, and topical creams.
CBD Oil Tinctures
Tinctures are one of the most popular and easy-to-use CBD products. They come in a variety of concentrations and types like flavored or unflavored oils.
Some tinctures can be dropped directly onto your tongue while others need to be mixed with food or drinks before consuming. Tinctures typically take between 15 minutes and 1 hour to take effect and last for as long as six hours.
If you want a more discrete way of getting CBD into your system, gummies are a good option. They taste great and can be taken on the go without attracting too much attention from others. However, they tend to be a bit more expensive than CBD oil tinctures and typically contain lower concentrations of CBD.
CBD Topical Creams
Topical creams are ideal for those who want localized relief from pain. This type of cream can be rubbed directly onto the skin as needed. The effects of hemp topicals like these tend to take longer to kick in than vaping or taking an edible. Topicals can last for as long as six hours and are great for people who suffer from arthritis, neuropathy, or other localized pain.
Will CBD oil topical creams help with nausea?
Now that you know more about CBD oil tinctures, gummies, and topical creams, it’s time to consider whether or not topical CBD cream will help with nausea.
Topical hemp products offer localized relief of pain which can be especially helpful for people who suffer from chronic stomach pain related to nausea. This type of cream is also easy to use on the go which makes it a good option for people who tend to feel nauseous when they’re out and about.
Topicals may also help with motion sickness, though more research is needed in this area before we will know for certain if CBD oil topical creams can effectively treat nausea related to motion sickness.
What if I don’t like the taste of CBD Oils?
If you don’t like the taste of tinctures or gummies, try edibles instead. Many people prefer to ingest their CBD this way since it offers long-lasting effects and can be quite potent.
CBD oil edibles come in a variety of forms- from chocolate bars to drinks to even popcorn! The best part? CBD edibles usually taste better than their oil counterparts.
How fast does CBD oil work for nausea?
CBD oil typically takes between 15 to 60 minutes before it starts relieving your symptoms. If you’re using a topical product, it can take much longer- up to six hours in some cases.
Is CBD Oil safe for me?
This depends on whether or not you’re looking at hemp CBD oil vs marijuana CBD oil. CBD products that are derived from hemp plants are non-psychoactive and considered to be legal in all 50 states.
CBD oil products that come from marijuana plants will contain THC, the cannabinoid responsible for causing a high, which can lead to an array of potential side effects.
Talk to your doctor before trying any type of CBD product to make sure it is right for you.
5 Best CBD Oils for Nausea
Final Thoughts on CBD Oils for Nausea
CBD may be an effective treatment for nausea associated with diseases like cancer or even chemotherapy side effects. More studies are needed to fully understand the risks and benefits of using CBD to treat nausea but many people report positive results- especially when used in conjunction with traditional treatments.
The best way to benefit from topical CBD oil is by using products that are designed for localized pain relief. This may be especially helpful for people who suffer from stomach pain related to motion sickness or other types of nausea. Be sure to consider edible forms of CBD as well if you don’t like the taste of CBD oils for nausea in the tincture form or gummy form.
