Nasal polyps are small benign (noncancerous) growths on the lining of the nose or sinuses. Many traditional treatments for nasal polyps exist. Because of its anti-inflammatory and antimicrobial properties, CBD is being explored as a complementary therapy.

Experts have recognized the potential of CBD for nasal polyps relief, but more research is needed.

This article will discuss the basics of nasal polyps, how CBD might help, and any known side effects.

The Endocannabinoid System and CBD

Your body has an endocannabinoid system (ECS), which regulates and controls bodily functions such as:

  • Learning and memory
  • Emotional processing
  • Temperature control
  • Pain control
  • Inflammatory and immune responses
  • Eating

The ECS is constantly working to keep your body in a state of equilibrium. It’s able to do this via two types of cannabinoid receptors found in select tissues:

  • CB1: The central nervous system (brain and nerves of the spinal cord)
  • CB2: The digestive system, peripheral nervous system (nerves in your extremities), and certain cells of your immune system

Cannabinoids from the cannabis plant can also affect these receptors.

Cannabinoids are a group of compounds that come from the cannabis plant (also known as marijuana).

The two main types of cannabinoids are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD).

What’s the Difference Between THC and CBD?

THC has a psychoactive effect and is derived from the marijuana plant. CBD doesn’t have a psychoactive effect and can be derived from the marijuana plant or the hemp plant.

CBD is of interest to the research and medical communities because of its potential for health benefits and treatments without the “high” of THC.

One area being studied is CBD’s effect on inflammation.

A 2009 study indicated that cannabinoids such as THC and CBD suppress the inflammatory response, which can help with symptom relief in inflammatory conditions.

Because of its antimicrobial properties, CBD is also being investigated as a possible new class of antibiotics in response to the current trend of antibiotic resistance.

These preliminary findings indicate the potential for CBD to be used in the treatment of nasal polyps. However, more studies are needed before this can be put into practice.

CBD for Nasal Polyps

Preliminary findings indicate the potential for CBD to be used in the treatment of nasal polyps. However, more research is needed.

What Are Nasal Polyps?

Nasal polyps are soft, sac-like, noncancerous growths that can grow anywhere on the lining of the nose or the sinuses.

They can cause symptoms such as:

  • Runny nose
  • Stuffed nose
  • Feeling like your nose is blocked and pain (if you also have a sinus infection)
  • Feeling like you always have a head cold

How Can CBD Help With Nasal Polyps?

Currently, there isn’t enough evidence to confirm that CBD can be used as an effective treatment for nasal polyps. Some studies do show promising data, but further research is needed to reach a conclusion.

Aspirin-exacerbated respiratory disease (AERD), also called Samter’s Triad, is a chronic inflammatory disorder that affects the sinuses and lungs. People with AERD have a sensitivity to aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs). Approximately 40% of people with nasal polyps, asthma, or chronic sinusitis will develop AERD.

A small pilot study that removed nasal polyps from people with AERD indicated that the endocannabinoid system may be involved in AERD. This suggests that cannabinoids might be a useful treatment. While this study was very limited and much more research is required, the results are encouraging.

A 2016 review indicated the potential of targeting the CB2 receptors for the treatment of inflammatory conditions. As CBD is a cannabinoid, it has the potential to activate these receptors and help with the inflammation associated with nasal polyps. More research into this is needed.

How to Use CBD for Nasal Polyps

The three main types of CBD are:

  • Full-spectrum: Contains other compounds from the cannabis plant, including THC (in varying amounts)
  • Broad-spectrum: Contains other compounds found in cannabis, but no THC
  • Isolate: Contains only CBD and no other cannabis compounds

CBD can be taken:

  • Orally: Such as in tinctures used under your tongue, or some medications
  • Topically: Such as in oils
  • In edible form: Such as in baked goods or candies
  • In inhaled form: Such as smoking or vaping (this isn’t recommended because of the potential for harm)

A CBD nasal spray may be beneficial for nasal polyps as it may improve bioavailability (the extent of the drug that enters the bloodstream).

There are currently no regulated CBD nasal sprays available, but as with other CBD products, unregulated ones exist.

The “Entourage Effect”

The entourage effect is the idea that full-spectrum cannabinoids may be more therapeutic because the cannabis plant contains active ingredients as well as “synergists” that boost effectiveness above that of the isolated compound. It has been likened to an orchestra supporting and enhancing the melody of a soloist. This effect is largely anecdotal, but there are some studies that show evidence to support it.


There isn’t a suggested dosage for CBD in the treatment of nasal polyps as it hasn’t been deemed an appropriate treatment yet.

With the exception of the use of CBD for epilepsy, there aren’t standardized doses for other conditions in the United States. A study in 2020 explored potential dosages for varying conditions, but the study had a number of limitations. Further research is needed.

How to Buy CBD

These days, depending on where you live, it’s typically easy to find CBD for sale online or in local stores. Some tips for buying CBD include:

  • Check the laws in your state: While all states have laws legalizing CBD to some extent, they have varying restrictions.
  • Look for a reputable source: Try to find a product that has been inspected by a third-party independent lab.
  • Read the label: Don’t assume the product is all-natural. If possible, choose an organic product that’s free of pesticides and other harmful chemicals.
  • Choose a product that’s not sourced in food: This can affect absorption.
  • Think critically and research your sources: Be wary of places selling products that make big, unverified claims that sound too good to be true.
  • Check with your healthcare provider: See if CBD is safe and recommended for you in terms of your condition, general health, and any medications you’re taking (including over-the-counter and herbal medications and supplements).

Are There Any FDA-Approved CBD Medications?

In 2018, the Food and Drug Administration (FDA) approved Epidiolex for the treatment of seizures associated with two rare and severe forms of epilepsy: Lennox-Gastaut syndrome and Dravet syndrome.

Epidiolex is an oral solution with CBD as its active ingredient. It’s the first FDA-approved drug that contains a purified drug substance derived from marijuana.

Are There Any Side Effects?

While CBD is generally considered safe, there are some possible side effects and safety concerns.

Possible side effects of CBD include:

Safety concerns include:

  • CBD can increase the level of coumadin (a blood thinner) in your blood.
  • CBD can raise levels of certain other medications in your blood.
  • There is a risk of allergy, especially to certain carrier oils that CBD is often combined with (such as sesame oil).
  • CBD may increase liver enzymes (a marker of liver inflammation), making it potentially harmful for people with liver disease, or necessitating regular tests for blood liver enzyme levels.
  • Cannabinoids can have interactions with other drugs.
  • The most effective therapeutic dose of CBD for any particular medical condition isn’t yet known.

CBD and Supplement Safety

CBD is marketed as a supplement in the United States, and the FDA doesn’t regulate the safety and purity of dietary supplements.

The active ingredients can vary from the dose listed on the label, from bottle to bottle, or even from dose to dose. It may also contain other (unknown) elements.

A 2017 study showed that among CBD products purchased online, the range of CBD concentrations varied widely, consistent with the lack of an accepted dose. Of the products tested, about 43% contained less CBD than labeled, which could make them less effective or ineffective. Some contained almost no CBD at all.


Nasal polyps are small benign (noncancerous) growths on the lining of the nose or sinuses. Many traditional treatments for nasal polyps exist. Because of its anti-inflammatory and antimicrobial properties, CBD is being explored as a complementary therapy.

Preliminary findings indicate the potential for CBD to be used in the treatment of nasal polyps. However, more research is needed.

CBD comes in various forms: topic, oral, edible, and inhaled. However, smoking CBD isn’t recommended. CBD can be bought online or at local stores.

While CBD is generally considered safe, there are some possible side effects and safety concerns. Talk with your healthcare provider to get a better sense of whether CBD is a safe treatment option for you.

A Word From Verywell

While research is very limited on the use of CBD in the treatment of nasal polyps, preliminary studies show promise, particularly when it comes to inflammation and antibiotic use.

If you have nasal polyps and aren’t already on a standardized treatment plan, consult with your healthcare provider to see what treatments would benefit you. If you would like to try CBD as a complementary treatment for nasal polyps, also check with your healthcare provider to make sure it’s safe for you.

Frequently Asked Questions

There is no research that shows nasal polyps can be removed with CBD. If you have or suspect you have nasal polyps, see your healthcare provider for a proper exam and to determine treatment.

Nasal polyps have similar symptoms to a head cold, but the symptoms either don’t go away or they go away and return quickly. If you feel like you have a head cold that has gone on too long, see your healthcare provider for an exam.

There is insufficient evidence of the benefits of CBD for nasal polyps at the moment. However, studies suggest that the anti-inflammatory and antimicrobial properties of CBD may be beneficial in the treatment of nasal polyps.

There are currently no regulated CBD nasal sprays available. As with other CBD products, though, unregulated ones exist. They have not been proven to help with nasal polyps, but preliminary research shows the potential for CBD to be used for the treatment of nasal polyps in the future.

How Effective is CBD Oil in Treating Nasal Polyps?

If you’re interested in using CBD oil for nasal polyps and related symptoms, research has shown that CBD can actually help.

If you’ve ever experienced nasal polyps or are experiencing them now, you know how bothersome they can be. While nasal polyps aren’t always a big issue, they can cause bigger concerns if not dealt with.

Continue reading to learn exactly what nasal polyps are, how to treat them, and if they can be prevented.

What are Nasal Polyps?

Nasal Polyps are soft, noncancerous round growths in the nose. They come from thin, soft tissue that lines the sinuses and nasal passages. While nasal polyps aren’t painful, they can get irritated. They can also swell up and cause blockage. Note that not all nasal growths are polyps.

If nasal polyps are small enough, you may not even experience symptoms since they’re soft and lack sensation. You may just feel as if you have a simple cold. However, large and/or groups of nasal polyps can affect your nasal passages and sinuses resulting in symptoms including:

  • Runny nose
  • Postnasal drip that runs down the throat
  • Nasal congestion or stuffy nose
  • Headaches and other facial pain
  • Teeth pain
  • Nosebleeds
  • Itchiness around the eyes
  • Sensitivity to smells
  • Sinus pain or pressure
  • Loss of taste or smell
  • Inability or difficulty breathing through the nose
  • Double vision (for rare and extreme cases)

If polyps grow big enough or develop in both nostrils, you could experience frequent sinus infections, trouble breathing, or sleep apnea. This happens because the nasal passages are blocked. If you’re someone with asthma, polyps can cause asthma attacks more often than usual.

What Causes Nasal Polyps?

Nasal polyps are complex so specific causes aren’t always known. However, common causes could be an infection or irritation due to allergies or certain immune disorders. Asthma, the common cold, cystic fibrosis, and nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen can also cause nasal polyps. If a nasal mucosa swells and becomes red, it can start to produce a fluid that may turn into a polyp.

Polyps can also simply be caused by genetics and how a person’s mucosa reacts to inflammation. While anyone can experience nasal polyps, they’re most often seen in adults and affect men more than women. Children with cystic fibrosis can develop nasal polyps.

Can CBD be Effective in Treating Nasal Polyps?

As CBD is becoming more popular to help improve health and wellness, you may be wondering if you can use CBD oil for nasal polyps. The short answer is yes, it can! Not only can CBD be used to alleviate nasal congestion, but it can help prevent nasal polyps and remedy other nagging symptoms when they do occur.

The body has something known as CB2 receptors that work to help regulate the immune system and inflammatory responses. Nasal issues occur if the receptors in the human endocannabinoid system (ECS) aren’t being activated as they normally should. These receptors are responsible for regulating the body’s processes and CBD oils work by activating the receptors to ensure that everything is balanced out.

Aside from nasal issues, using high-quality CBD is a natural way to improve the body’s overall health.

When considering using CBD oil for nasal polyps, it’s important to be aware of the different types:

  • Full-spectrum CBD: consists of all naturally occurring elements of the cannabis plant including THC
  • Broad-spectrum CBD: similar to full-spectrum in that it consists of all components of the cannabis plant, but all THC is removed
  • Isolate CBD: contains only Cannabidiol and no other components

Can You Put CBD Oil in Your Nose?

If you’re looking to prevent or treat nasal polyps, you might be wondering if CBD oil for nasal polyps can be put into your nose. It is actually safe to do this if using a product meant for inhaling through the nose.

While the popular CBD oil tincture is taken under the tongue or added to a beverage, a CBD nasal inhaler would be most effective in helping (or possibly preventing) nasal polyps.

  • When CBD oil for nasal polyps is breathed in through the nose, it can provide quicker relief than other methods such as nasal sprays, tinctures, and consumables. However, it’s important to note that it doesn’t provide immediate and complete relief.
  • CBD nasal inhalers are discrete and easy to carry with you.
  • They work with CB2 receptors to decrease symptoms of nasal polyps and can help to prevent future polyps from occurring.
  • They also work with CB1 and CB2 receptors in the body to relieve stress and anxiety and leave you feeling refreshed.
  • They’re safe to use and don’t have any known side effects.

Other Common Treatment Options for Nasal Polyps

After nasal polyps are diagnosed by answering questions and potentially performing a physical exam, there are other treatment options aside from CBD. Here are some common methods that can reduce the size of polyps or eliminate them.

Keep in mind that sprays and medications may need to be used for a couple of weeks before seeing any results.

  • Steroid sprays: usually the first treatment; reduces runny nose and shrinks the size of polyps
  • Oral or injectable steroids: used short term and do have side effects if used too much
  • Antihistamines or antibiotics: can treat allergies or sinus infections that occur from or result in nasal polyps
  • Surgery: this could be to place a stent to open up the nasal passage and deliver medications or to use endoscopy to remove polyps that aren’t improving with other treatments; the type of surgery depends on several factors such as size, severity, and symptoms

There are also at-home treatments that have been used to treat nasal polyps. However, be sure to consult with a medical professional if symptoms are severe.

  • Cayenne pepper: That’s right! Research has shown that consuming red pepper can improve inflammation, open up nasal passages, and boost immunity. Keep in mind that this doesn’t necessarily mean nasal polyps will be prevented or completely treated, but it can reduce symptoms.
  • Garlic and/or ginger: Consuming a liberal amount of garlic and/or ginger can help fight infections and reduce inflammation. You can also use it as a powder supplement or extract.
  • Inhaling hot steam: Taking a hot show or bath, using a humidifier, or steaming water on the stove can alleviate symptoms.
  • Essential oils: Essential oils including tea tree oil, chamomile, eucalyptus, and peppermint can help. You can mix it in the water for your hot steaming, dab it below your nose, or add it to a hot tea. An essential oil roll-on can also help.
  • Vitamin D: Increasing Vitamin D intake can support the immune system.

Preventing Nasal Polyps

After treating nasal polyps, it’s common for them to come back. Of course, the best-case scenario is to prevent them to begin with. While it’s not always possible to keep them from occurring, there are ways to reduce the risk and potential symptoms:

  • If you suffer from allergies and/or asthma, take medications as directed by a healthcare provider.
  • Use a humidifier to create moisture for your nasal passages, especially if you live in a dry environment. Be sure to clean the humidifier regularly to prevent bacteria build-up.
  • Create a regular habit of using a CBD oil for nasal polyps.
  • Use a nasal rinse or spray to clear the nose of possible allergens and improve mucus flow.
  • Practice good hygiene such as frequent hand washing
  • Avoid nasal irritants such as breathing in chemical fumes and tobacco smoke.

Things to Keep in Mind

While nasal polyps can be annoying, they aren’t usually something to worry about. They can typically be treated at home if caught quick enough, but consult with a doctor if symptoms are persistent or severe.

Practices mentioned such as CBD nasal inhalers, humidifiers, and proper hygiene can relieve and prevent nasal polyps.
