Best CBD Oil for Cancer Treatment: Does It Help and Where To Buy?

CBD oil is everywhere.

That’s not a joke, it’s literally everywhere.

At novelty or vitamin shops, pharmacies, fitness studios… Even your local grocery store carries CBD oil these days.

Scientists are fueling serious resources into the research on the possibility of treating cancer and its side effects with cannabinoids such as CBD.

As the popularity of plant-based extracts is growing by leaps and bounds, the potential benefits of CBD oil for cancer patients is excellent news for those looking for natural ways to help their close ones improve their quality of life during those hard times.

In this article, we’re going to explore scientific research when it comes to using CBD to combat cancer and its symptoms.

We’ll also get you through a compilation of CBD oils that could potentially aid individuals during their treatment in a safe way.

Where to Buy the Best CBD Oil for Cancer in 2022?

The following ranking is a compilation of CBD oils that we’ve chosen after going through over 40 brands available both locally and online. They have been chosen following the quality criteria such as hemp source, extraction methods, company’s transparency, and customer service.

1. Royal CBD (Best CBD Oil for Cancer)

Product Details

Potency 250 mg – 2500 mg
Available Flavors Natural, Berry, Mint, Vanilla
CBD per serving 8.3 mg – 83.3 mg

Why Royal CBD is the Best Oil for Cancer

My history with Royal CBD oil began two years ago when I stumbled upon them doing my daily news overview. Attracted by the simplicity of their product line up — they only had a few options of full-spectrum CBD oil back then — and commitment to the cannabis community, I decided to give them a try, and here we are after two years, still my number one product.

Royal CBD oil is available in four different concentrations, including 250 mg, 500 mg, 1000 mg, and 2500 mg. You can choose from flavors like Berry, Mint, and Vanilla, save for the highest potency, which only comes in the neutral option. This is a full-spectrum product, meaning it contains all the non-psychoactive cannabinoids and terpenes originally found in hemp. I’ve been getting great consistent results when it comes to pain relief using the 2500 mg bottle. The oil has also reduced my anxiety and helped me sleep better, although I wake up an hour or two earlier now (but better rested).

Note: Royal CBD is only available online; you won’t find it in any local store, at least not yet.

Pros Cons
  • Made from locally grown organic hemp
  • Extracted with supercritical CO2
  • Infused with full-spectrum CBD
  • Available in 4 strengths and flavors
  • Up to 2500 mg of CBD per bottle
  • 3rd-party tested for potency and purity
  • Great natural flavor
  • Not available in local CBD stores (this may soon change)

2. Gold Bee (Best Flavor)

Product Details

Potency 300 – 1200 mg
Available Flavors Natural, Honey
CBD per serving 8.3 mg – 33.3 mg

About Gold Bee

Gold Bee is a California-based manufacturer that specializes in making honey-flavored CBD extracts. The company has created its own blend of CBD-rich strains in partnership with local growers as well as with farmers from Colorado. These plants are grown in healthy soils and without pesticides or growth boosters.

On top of the premium quality of ingredients, I think this brand deserves much love for how they mix CBD with honey. The flavor is very natural and masks the earthy hemp aftertaste I’ve been getting with other oils. I noticed similar results with my pain and stress to what I got from Royal CBD, but the reason I place Gold Bee as the second-best CBD oil for cancer is the lack of high-potency oil in its selection.

However, if you benefit from low-to-moderate doses of CBD, this is a very decent company to purchase from.

Pros Cons
  • Sourced from US-grown organic hemp
  • Contains full-spectrum CBD
  • Up to 33 mg CBD/mL
  • Great potency range for beginners
  • Third-party tested for potency and purity
  • Great honey flavor
  • No high-strength CBD oils

3. CBDPure (Best Transparency)

Product Details

Potency 100 – 1000 mg
Available Flavors None
CBD per serving 3.3 – 33 mg/mL

About CBDPure

Similar to Gold Bee, CBDPure offers mostly low-potency CBD oil. Recently, the company has added a 1000 mg potency to their line up, which, of course, I had to try.

The thing that always made me feel strange about CBDPure is that these low-potency oils work better than some high-strength products I’ve tried in my life. For me, CBDPure is the benchmark for the quality of full-spectrum CBD extracts. I’ve been getting great results with this oil for my anxiety as well as issues with appetite. The effects were similar to what I’ve experienced with the two other brands.

CBDPure is our third-best CBD oil in this compilation because both Royal CBD and Gold Bee turned out more affordable for me in the long run.

Pros Cons
  • Sourced from organic Colorado-grown hemp
  • Extracted with supercritical CO2
  • Lab-tested for potency and purity
  • 90-day return policy
  • Only two forms of CBD available
  • Low potency
  • Premium pricing

4. Hemp Bombs (Best CBD Isolate)

Product Details

Potency 125 – 4000 mg
Available Flavors Natural, Acai Berry, Orange Creamsicle, Peppermint, Watermelon
CBD per serving 4 – 133 mg/mL

About Hemp Bombs

Hemp Bombs is a U.S. company that specializes in making CBD oil made from 99% pure isolate. The guys at Hemp Bombs cover the entire potency range for CBD extracts, offering up to 4000 mg of CBD per bottle.

This CBD oil is a great alternative for cancer patients who, for some reason, don’t want to take any THC with their oil. Full-spectrum products contain 0.3% THC or less. While it’s not enough to get you high, CBD isolate is completely free of THC.

Plus, you don’t need to worry about the botanical scent and earthy flavor because CBD isolate is flavorless and odorless.

I like the way this CBD oil worked for my sleep routine. Normally, I’m not used to taking high doses of CBD, but since Hemp Bombs offers the highest CBD dose per serving, I decided to give it a try before bed and I must say I felt asleep much easier and I had fewer dreams throughout the night.

However, there’s no entourage effect from other cannabinoids and terpenes, so Hemp Bombs may not be appropriate for those looking for the whole-plant synergy.

Pros Cons
  • Sourced from organic hemp
  • Extracted with CO2
  • 0% THC
  • Available as broad-spectrum or isolate
  • Third-party tested for CBD and contaminants
  • Up to 4000 mg of CBD per bottle
  • 5 strengths to choose from
  • Infused with synthetic flavorings
  • No “entourage effect” from other cannabinoids and terpenes
  • Most people don’t need such high doses of CBD oil in their routine

5. CBDistillery (Best Price)

Product Details

Potency 250 – 5000 mg
Available Flavors None
Potency 8.3 – 166 mg/mL

About CBDistillery

CBDistillery is one of the largest suppliers of CBD oil in North America. The company was established by a group of Colorado citizens based on a mutual goal to provide high-quality CBD products at affordable prices. CBDistillery’s oils are available in an extremely wide range of concentrations, from 250 mg to a massive 5000 mg of CBD per bottle. The strongest version carries 166 mg of CBD in each milliliter, which is enough to get yourself stocked up with CBD for months to come.

You can also choose the cannabinoid spectrum in your CBD oil because CBDistillery sells both full-spectrum and broad-spectrum extracts. In the broad spectrum, THC has been completely removed after initial extraction, but the other cannabinoids and terpenes from the plant are still there.

CBDistillery scores the last place on our list of the best CBD oils for cancer due to its hemp source — the plants used by the company aren’t organic.

Pros Cons
  • Available as full-spectrum or broad-spectrum CBD
  • Extracted with CO2
  • 5 potency options to choose from
  • Up to 166.6 mg of CBD per bottle
  • Third-party tested for potency and purity
  • Very affordable
  • Made from non-organic hemp
  • No flavored options

What is CBD?

CBD is one of 113+ compounds in cannabis which are referred to as cannabinoids. Unlike THC, another major cannabinoid, CBD isn’t psychoactive, meaning you won’t get high off of it.

It turns out that all humans have an endocannabinoid system (discovered in the 1990s), which is an imperative regulatory network of cannabinoid receptors and neurotransmitters known as endocannabinoids. Endocannabinoids are released to maintain homeostasis in the body, which is a state of biological balance between all bodily functions, such as emotional processing, memory, pain signaling, sleep cycles, immune response, and more.

CBD is a modulator of the endocannabinoid system. In other words, it signals this network to produce and maintain more of its endocannabinoids to help them effectively maintain homeostasis.

CBD can also help the endocannabinoid system when homeostasis has been already compromised. Through the aforementioned signaling, it can stimulate the production of healthy cells in the body while triggering the process of apoptosis — the destruction of degenerated (cancerous cells).

People use CBD for a variety of reasons, from common anxiety to inflammatory issues to serious chronic conditions, such as epilepsy, autism, arthritis, and cancer.

What is CBD Oil?

CBD oil is a concentrated extract sourced mainly from hemp plants for its high CBD content. The oil is extracted from hemp flowers, the resinous part. After initial extraction, CBD oil is usually filtered of redundant plant material and suspended in a food-grade carrier oil, such as MCT oil.

CBD oil is available in glass bottles with convenient droppers attached to them. These droppers are included for easier and precise dosing.

To take CBD oil, you need to squeeze it beneath the tongue and hold it there for about one minute to let it absorb through special capillaries in the mouth.

CBD Oil for Cancer-related Symptoms

The research into CBD’s potential use as a treatment for cancer is still in its infancy. The FDA doesn’t approve CBD oil as a means of managing the symptoms of cancer, and there’s only one pharmaceutical on the market containing this cannabinoid. Its name is Epidiolex. However, Epidiolex is for epilepsy patients, not for those fighting cancer.

If you want to use CBD oil to assist your cancer treatment, make sure to consult with your doctor to get a bigger image of how CBD oil could help you.

While CBD oil isn’t a cure for cancer, it can surely help you alleviate several of its symptoms as well as some side effects of chemotherapy and radiation.

This is where we’re going to start.


Studies have indicated that CBD interacts with the mechanisms in the brain that are responsible for nausea and vomiting. Many patients regularly use cannabinoids to reduce the uncomfortable sensation of nausea as a side effect of chemotherapy and other medications. On top of the above, CBD regulates serotonin, reducing the stimulation in the brain’s area that triggers vomiting.


In a 2015 survey run by Care By Design, the majority of patients who took CBD oil for pain and inflammation reported relief from their symptoms. CBD influences specific receptors in the brain that may reduce inflammation and block pain signaling. Pain is one of the most prevalent symptoms of cancer — and a side-effect of chemotherapy — so these are very promising findings for cancer patients.

Fatigue and Sleep Problems

CBD and other cannabinoids are adaptogens, meaning they can promote homeostasis within the body without causing any side effects in its functioning as well as in the brain structure. Adaptogens are also referred to as “smart molecules” because they can go where they are needed the most to promote balance and speed up regeneration processes, such as neurogenesis. If a cancer patient suffers from a lack of sleep, CBD may help reduce some of the stress and anxiety that are often linked to this condition. This can contribute to safe and gentle sleep regulation.

On another note, when chronic fatigue and lack of energy are the problems due to cancer or medication, CBD may help target the specific actions in the body to provide it with sufficient energy levels and vitality on top of enhanced focus and the aforementioned stress relief. Some scientists call CBD “the boy scout molecule” because it always makes it to the right point in any given situation.

Loss of Appetite

Although some people report appetite suppression after taking CBD oil, it turns out it may have an opposite effect on others. When CBD binds to specific receptors in the brain, it can stimulate your appetite. Because most cancer patients suffer from loss of appetite, this particular feature of CBD oil can be helpful in assisting the body’s needs for nourishment that is so much needed during the disease and after chemotherapy.

Can CBD Oil Help Cure Cancer? 

When you look at anecdotal evidence from people on the Internet, many of them claim they have been cured of cancer by using cannabis. Scientific research conducted on animals suggests that CBD can shrink tumors and stop them from spreading. For example, a 2011 study showed that the stimulation of the endocannabinoid system through the combination of cannabinoids and fatty acids could potentially relieve prostate cancer.

Another study published in Plus One pointed to CBD as the effective anti-cancer agent, highlighting its ability to trigger the death of cancer cells and prevent tumor growth by reducing the number of certain proteins that are involved in spreading tumorous cells. The researchers recommended supporting CBD as an anti-cancer substance due to its safety and lack of dangerous side effects.

We’ve also examined the Cure Your Own Cancer site, where patients file their testimonials about having been cured of cancer using cannabis oil. The website, founded by a young activist Lincoln Horsley, provides a lot of free information about cannabis, cancer, and how to combine cannabinoids to support yourself on your way to recovery.

Now, the problem with using CBD oil for cancer is that there haven’t been many human trials regarding this subject. Therefore, consumers must realize that while anecdotal information about CBD and cancer is very promising, it must be scientifically tested before being approved as a form of treatment.

Is CBD Oil Legal?

CBD can be extracted from both hemp and marijuana, so it’s no wonder you may have questions about its legal status.

When it comes to marijuana-derived CBD oil, you can legally buy it if you live in a state that has legalized the medical or recreational (or both) use of marijuana. Currently, 11 states have recreational laws and 30 other states have some sort of a medical marijuana program.

Hemp-derived CBD oil is subject to different regulations. In 2018, President Trump signed the amended version of the Farm Bill into law, legalizing hemp on the federal level. Hemp is no longer on the list of controlled substances. It’s an agricultural commodity and you can legally buy hemp-derived products in all 50 states.

Summarizing the Use of CBD Oil for Cancer

Scientists agree that CBD oil has some benefits for cancer, but there is still much to learn about this subject before we can draw any conclusions. Nevertheless, the future looks bright for CBD oil and the health benefits it comes with.

For example, in the Spanish Observatory on Medical Cannabis, some of the world’s top cannabis scientists are aggressively researching cancer treatment with cannabis, regularly reporting on their findings.

If you want to try CBD oil to assist your cancer treatment and reduce some of the pesky side effects of chemotherapy, consult your doctor about it, and most importantly, always buy your CBD from a trusted source that can provide lab-testing reports.
