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.

Can CBD Oil Help With Nausea?
All mammals have an endocannabinoid system — a series of receptors and hormone-like compounds that control homeostasis (balance) throughout the body.
One of the responsibilities of the endocannabinoid system is to regulate a special region in the medulla oblongata that controls the reflexes that trigger nausea and vomiting.
Research involving a new drug that blocks the endocannabinoid system shows that those given the drug often experienced nausea as a side-effect . This is an excellent demonstration of the role the endocannabinoid system plays in regulating nausea in the brain.
Blocking the endocannabinoid system makes us feel nauseous while boosting it eliminates nausea.
Other research involving a synthetic version of THC was shown to alleviate nausea and vomiting, supporting this theory even further .
Summary: Using CBD Oil For Nausea
- THC offers the most benefits for nausea. Find a full-spectrum extract with at least some THC content to get the most benefits for nausea relief.
- Always seek out high-quality CBD products. Poor manufacturing processes often use rancid oils and harmful additives that can lead to nausea.
- In order to get the biggest benefits, cannabis extracts need to be used at the first sign of nausea.
- For maximum anti-nausea effects, combine your CBD or hemp extracts with a strong ginger tea or other anti-nausea supplements.
Nausea begins with that queasy feeling in the stomach, accompanied by an urge to vomit. There are many different things that can cause nausea. The best treatment often depends on what triggered the queasiness.
Feelings of nausea originate in the brainstem in a special region known as the medulla oblongata. This region of the brain is responsible for regulating many of our autonomic (involuntary) functions such as breathing, sneezing, and vomiting.
Our automatic functions are regulated by higher regions of the brain that send signals to the medulla oblongata to make adjustments accordingly.
In the case of nausea, the brain activates the urge to vomit in an attempt to rid the digestive tract of toxic compounds (drugs or alcohol), infectious agents (bacteria or viral infections), or by mistake from abnormal neurological activity involved with migraines or brain tumors.
What Causes Nausea?
There are literally hundreds of different causes for nausea. The most common by far is food poisoning and other digestive system infections, accounting for as much as 37% of nausea cases. Roughly 3% of cases are reported to be the result of medication side-effects and pregnancy, while up to 10% of cases have no identifiable cause .
Nausea is also more common in young people. Children are the largest group of people who experience regular episodes of nausea, while people over the age of 65 appear to be affected the least .
Common Causes of Nausea:
Treatment Options for Nausea
There are pharmaceutical, herbal, nutritional, and lifestyle modifications that can be used to treat nausea. Not all of them work, and some are more specific for certain causes of nausea.
Treatments for Nausea Include:
- Antiemetic medications (such as Zofran)
- Ginger root (Zingiber officinalis)
- Cannabis (Cannabis)
- Peppermint (Mentha piperita)
- Chamomile (Matricaria chamomilla)
- Antibiotic medications (such as amoxicillin, doxycycline, cephalexin)
- Opioid pain medications (such as oxycodone, morphine, fentanyl)
CBD vs. THC for Nausea
Cannabis is a reliable treatment for nausea and vomiting. It works through a couple of different pathways affecting the nausea center in the brain, as well as through indirect mechanisms that help manage many of the underlying causes of nausea.
The most significant effect of cannabis when it comes to treating nausea is from the effects of THC — the main psychoactive compound in the cannabis plant. THC works by activating the CB1 receptors found in the medulla oblongata, the area responsible for making us feel nauseated . By activating these receptors, we can inhibit nausea.
CBD has also been shown to reduce feelings of nausea, though it’s not considered to be as effective as THC.
Most of the benefits from CBD are likely to come from its ability to increase anandamide levels, indirectly activating the CB1 receptors in the medulla through anandamide.
Anandamide and THC are similar structurally and activate the same receptors in the body.
Using CBD Oils with THC for Nausea
THC remains illegal for most of the world — however, times are changing.
Until the laws open up around the use of THC, it’s unlikely that you’ll be able to find any products with this ingredient in concentrations over the 0.3% threshold.
THC doesn’t need to be psychoactive to be effective for nausea. THCA (THC-acid), the raw (unheated) version of the compound is non-psychoactive and has been shown to offer a similar level of anti-nausea benefits as activated THC.
As laws change around THC, it’s likely that there will be new companies popping up that sell non-psychoactive THC and THCA-rich cannabis preparations aimed at treating nausea and vomiting.
Until then, we’ll have to use the high-CBD hemp extracts. In order to maximize the benefit of these products, it’s recommended that you search for a full-spectrum extract that contains the whole gamut of cannabinoids including CBG, CBC, CBN, and indeed, THC (needs to be less than 0.3% to be legal in most places).
To really supercharge the anti-nausea effects, it’s recommended that you mix your CBD or hemp extracts with a strong ginger tea. Ginger is one of the best anti-nausea herbs available and uses different mechanisms than cannabis. When combined, the effects of the two herbs compound through a concept known as synergy.
The results of doing this are very impressive.
Mixing Cannabis With Other Anti-Nausea Herbs
For maximum benefits, we recommend mixing your CBD oil with other anti-nausea herbs.
This is useful because different herbs usually offer their anti-nausea benefits through separate mechanisms. These effects combine to produce even stronger effect profiles. This is a common technique used by professional herbalists for treating nausea — which is difficult to treat with single-herb preparations.
Mixing your CBD with herbs on the list below improve nausea relief, and can make the effects appear faster.
Other Herbs With Anti-Nausea Benefits:
You can take these herbs as tinctures, capsules, or as a strong tea. Always follow the directions on the package when using herbal supplements because the dose will vary according to how it’s manufactured.
What’s The Dosage of CBD for Nausea?
Figuring out the effective dose of CBD oil for nausea can be difficult — this is because the effects of CBD can vary significantly from one person to the next.
There are some general guidelines you can follow to estimate what the most likely dose you’ll need might be.
Below, we’ve outlined the rough weight-to-strength dosages for CBD oils.
When it comes to nausea, some people find relief at the low-strength, others need the high-strength doses to provide any benefit. The only way to find out how this works for you is to try it out. Start with the low dose, and build up gradually to the higher doses until you find relief from symptoms.
