CBD Oil And Nausea: Science, Effects & What To Try

Posted: September 04, 2020

Cannabidiol, otherwise known as CBD, is used by individuals for a number of benefits, including to relieve and improve unwanted symptoms of many illnesses and ailments. This includes being used for its anti-inflammatory properties and relaxing effects, to name just a few. Here we are going to investigate what CBD is, how it can help to alleviate the feeling of nausea and sickness, and which kinds of CBD products are the best to use depending on your preferences.

What is nausea and some of the causes?

Nausea itself can be a very unpleasant defensive mechanism of the body, which can be either short-term or chronic. It is often referred to as feeling sick, having a queasy stomach and feeling as if you are about to vomit. If you experience nausea, it is best to consult with your GP to determine the cause. It can be a symptom of an underlying condition. Possible causes include:
  • Migraines
  • Ear infections
  • Head injuries
  • Pain
  • Heart attacks
  • Medication or treatments, including chemotherapy
Other symptoms may occur, such as dizziness and a sensitivity to light.

What is CBD?

In cannabis plants there are over 113 identified cannabinoids and one of them is called CBD or cannabidiol. Unlike THC (which is highly psychoactive), CBD is a non-psychoactive compound. The WHO (World Health Organisation) states that CBD does not cause a high or cause detriment to health. CBD is widely used for symptoms and illnesses such as (but not limited to):
  • Epilepsy
  • Depression
  • PTSD
  • Stress
  • Pain relief
  • Neuro-protection
  • Anti- seizure
  • Parkinson’s disease
  • Anxiety
  • Bacterial infections
  • Irritable Bowel Syndrome (IBS)
CBD oil is extracted through various scientific methods using specialist equipment. The extraction process is long and complicated. CBD can be extracted and isolated to a pure state (this is what is known as an isolate) and can also be extracted to be left containing other cannabinoids , terpenes and flavonoids (these products are commonly known as full spectrum and broad spectrum). More often than not these latter products are more organic than its isolate counterparts. For more information on full spectrum CBD oil, please read our guide on the entourage effect.

Benefits of CBD oil for nausea

There are many ways in which CBD can benefit our body, including helping relieve nausea. CBD can induce a feeling of relaxation, create an internal harmony or homeostasis and relieve symptoms of many often painful or uncomfortable conditions. When we take CBD products they interact with various receptors around our body and in our brain, which can trigger positive processes in our body. In this way, CBD reduces nausea because it interacts with our 5-HT receptor, which is our serotonin receptor. When we take a CBD product, it is shown to help alleviate vomiting and nausea.

The 5-HT receptor

The 5-HT receptor is responsible for mediating excitatory and inhibitory neurotransmission. These same receptors are the influencer of many neurological and biological processes, such as appetite, cognition, aggression, learning, memory, nausea, sleep and temperature regulation. These receptors are also found in almost all animals.

How does CBD work to alleviate the symptoms?

CBD interacts with the serotonin receptor found in our brain called 5-HT. When it does this it reduces nausea and can stop vomiting. In our body we also have an endocannabinoid system. CBD interacts with our CB1 and CB2 receptors to provide many physical and mental health benefits.

How to take CBD for nausea

vape pen The range of CBD oil products is forever expanding and new, easier ways to take CBD are becoming more accessible (and known) to a much larger audience. There are many ways in which we can take CBD and it generally comes down to personal preference. We can choose between edibles, e-liquids, water soluble oils and many other revolutionary CBD products.


One of the most simple ways to take CBD products is by eating edibles as: they are tasty, perfect for on the go or at home, and each edible states exactly how much is in each piece. This makes it easier to monitor and regulate your own unique dosage, all whilst being able to quickly enjoy a delicious snack or treat.

Oral oils

Another effective way of getting your CBD dose is using an oral oil. Some of these can be taken sublingually (held under the tongue) or dropped into water or juice and stirred in. This method is effective and fast and again, simple for on the go or at home. It is also discreet and easily manageable. Oral oils come in a wider range of strengths and some even come with added turmeric or other supplements.

Vape oils

Alternatively CBD comes in vape oil or e-liquids. Although certainly not as easy to prepare and less discreet, CBD vape liquid is remarkable in that it is possible to get a strong, large dose and feel the effects almost instantly. The variety in flavour is also unmatched. If you are looking into vape oils or e-liquids, it is important to note that they can cause respiratory problems and are not recommended for everyone, especially if you have a pre-existing respiratory condition.


There are pure CBD crystals and oils, which can also be great for creating your very own, custom CBD edibles. These are certainly worth a look if you are interested in making a tailored product to suit your own tastes and strength needs. We have kits available that contain everything you might need to create your perfect CBD treat. Read our blog guide on making homemade edibles, looking specifically at CBD gummies.

How much CBD oil to take for nausea

When you take CBD it is up to you to control and monitor the dosage. There are no prescriptions and no scheduled time or intervals at which to take it. Most CBD products have a recommended or maximum daily dosage and it is advised to not exceed it. For anyone new to CBD, you should first consult your GP. If you decide to try it, it is highly recommended to start with a low dosage and then top up until you reach your desired effects. For example a full spectrum water soluble oil might suggest 2-3 drops but no more than 5 per day. Try starting with 2 or 3 and if the required relief or effects are not achieved, then perhaps try one or two more drops on a different day. For this process it is worthwhile to keep a diary noting the drops you use and the effects achieved. Keep in mind that the effects of vape products and water soluble products can be felt much faster than a product that requires metabolisation. Edibles and oils must be processed by our bodies and it can take up to 2 hours before we feel the effects.
