Could CBD Help This Cold Season?
When winter is coming, you can bet there’s going to be an uptick in tissue and menthol throat lozenge sales. And don’t forget the cold prevention approach, with herbal supplements a-plenty.
Could CBD be a part of the new cold solution arsenal? That’s what we’re here to get to the bottom of.
We’re clearing away the congestion to learn:
- Does CBD help if you have a cold?
- Can CBD prevent you from catching a cold?
- If so, how do you use CBD to reap those benefits?
You might have the sniffles right now, or there could be a cold virus lurking in the very room you occupy — so let’s get down to it.
Understanding The Common Cold
How does that old saying go? Oh, yeah. “Know thy enemy.”
It doesn’t matter if you’re aiming to prevent a cold or handle one you already have — you’ve gotta know what you’re up against. So let’s get familiar with our foe.
The common cold is a viral infection of the upper respiratory tract (nose and throat). It spreads through droplets in the air, physical contact, or sharing a contaminated item, like a drinking glass. It enters through the eyes, nose, or mouth.
Although colder months are peak cold season, you can catch a cold anytime of year.
The cold is usually caused by a strain of rhinovirus, but a lot of different viruses can cause a cold. They all have similar symptoms.
- Runny nose or stuffy nose
- Sore throat
- Body aches
- Low-grade fever
- And feeling like you just wanna be under a heated blanket with your comfort show on replay…
… are all common cold symptoms.
Speaking of knowing your enemy: It’s important to know if what you’re dealing with is a cold or something else, like say, COVID-19 or flu. Be sure to go through the proper protocols to rule out the coronavirus or flu before you assume you’re dealing with a regular old cold.
This Is Your Immune System On Colds
Once a cold virus invades your body, your immune system is the superhero that comes in to save you from imminent nose-blowing and rib soreness from coughing. (Seriously, who knew there were muscles there?!)
This is what that counter-attack looks like.
- It starts by sounding the alarm that a foreign invader has arrived. This is done by sending messenger proteins called cytokines to your white blood cells, brain, and blood vessels.
- White blood cells travel through your bloodstream, so your blood vessels expand to make way for more of them to come in and combat the virus. This is when things start to get uncomfortable with symptoms setting in.
- The white blood cells have to make your body a not-great place for the pesky cold virus. So they dilate blood vessels even further and occupy more space. This is the peak “I want my mommy” phase of a cold, with fever and other symptoms cranked up to 10. The good news is that your white blood cells are also making antibodies to prevent the virus from coming back.
- Finally, the virus is defeated. Huzzah! This is when you can expect leaky faucet situations as your nose is the main pathway to flush out the fluid your body has accumulated from the immune response.

CBD & The Common Cold
So, what do we know about CBD and colds?
With colds generally lasting around a week and not being life-threatening, they aren’t at the forefront of priorities for CBD research. So we don’t know a ton about colds specifically.
But being colds are viruses, we can draw some conclusions about CBD research for viral infections. We can also look at what CBD might do for cold symptoms.
Here’s the current download.
CBD Could Ease Cold Symptoms
Remember the immune response we learned about above? The symptoms that result from this immune activity are caused by two main actions:(1)
- Inflammation brought on by white blood cells being ushered in and fighting off the virus. The result is congestion, body aches, a sore throat, and eventually a runny nose when the virus KO job is coming to an end.
- Your brain bumps up its core temperature to make your body an unhappy place for the virus. The result is a fever.
CBD acts on a system in the body called the endocannabinoid system (ECS). This recently discovered system has ties to the immune system. We’re still learning about the relationship, but we know CBD has anti-inflammatory and immunosuppressive properties that may reduce the intensity of these responses.
That means CBD might help you weather your cold more comfortably. And with evidence pointing to CBD supporting sleep, CBD oil could help you sleep through the worst of it.(2)
Compounds In Cannabis Could Prevent Viral Infections
Aside from the well-known cannabinoids CBD and THC, cannabis also contains compounds called terpenes.
The antiviral properties of terpenes have long been known, in part because cannabis isn’t the only plant that has them.(3)
Terpenes found in cannabis and CBD are currently being explored as an antiviral to prevent the contraction of COVID-19.(4) Preliminary research used a relative of COVID-19 and the common cold. So far, researchers have found the most effective way to prevent infection is a combination of terpenes and CBD.
All this suggests that CBD oil rich in terpenes could be a worthy addition in your cold prevention toolkit.
Take a deep dive into the wonderful world of terpenes in the article calledWhat Are Terpenes & Why Do They Matter?
Using CBD For Colds & Cold Prevention
Now you know the science behind CBD versus cold viruses, you might be wondering how to use CBD products to prevent a cold or manage the symptoms.
It all comes down to safety, smoking, and spectrums.
Run It Past Your Doc
Most people tolerate CBD very well. If side effects do occur, it’s rare. They include dry mouth, diarrhea, drowsiness, and reduced appetite.
But remember, CBD can suppress the immune system. For healthy adults, this usually isn’t an issue. That’s why it’s okay to take cold medicine and anti-inflammatory pain relievers when you have a cold.
However, if you have an autoimmune condition (or any medical condition), you should definitely consult with your doctor before using CBD for your cold (or anything else). CBD can interact with other medications and isn’t recommended for use with all health conditions.
Don’t Smoke! (Do This Instead)
Smoking irritates your respiratory system, so smoking cannabis or vaping CBD when you have a cold isn’t ideal. It can also make you and those around you more susceptible to respiratory infections.(5)
But with so many fantastic CBD products out there, you won’t have any trouble getting a dose in. You could take CBD with melatonin in your bedtime tea, take a water-soluble CBD softgel for fast-acting relief, or chew a CBD gummy.
And while you’re at it, you may as well make it a gummy made with immune boosting in mind, like these CBD gummies with elderberry, zinc, and vitamin C.
Use Broad-Spectrum CBD Oil
If you want the power of terpenes, you need a CBD oil that’s loaded with ‘em. Let’s deduce which type of CBD to choose.
- Isolate CBD is processed to remove everything except CBD, and it loses terpenes in the process.
- Full-spectrum CBD is an option, but it may contain more THC than is legal or than you want.
- Broad-spectrum CBD still contains terpenes with zero or virtually no THC. (The max THC content is 0.3%.)
That makes broad-spectrum CBD the best bet for getting your terpenes. Best part? It’s federally legal, so you can likely find it locally — or keep your germs to yourself and order it online!
We’re Just Getting Warmed Up
Looking at the science, we still have a lot to solidify before we know exactly how and why CBD could be an effective cold remedy or tool for cold prevention.
However, CBD’s properties do seem to ease inflammation and symptoms associated with colds. And, the combo of terpenes and CBD may prevent viral infections.
If you want to try CBD this cold season, first make sure it’s safe to use with your current medical treatment plan. To get the potential benefits of terpenes for colds, use broad-spectrum CBD. Avoid the risks associated with smoking by choosing from the many edible CBD products.
CBD Oil for Colds – August 2022
Research shows that the chemical compound CBD interacts with receptors in the endocannabinoid system (ECS) (7) . The ECS helps regulate functions of the nervous, cardiovascular, and immune systems (8) .
Scientists suggest CBD can attach to cannabinoid receptors, including CB1 and CB2 receptors, to suppress the inflammatory response (9) .
The authors of a 2008 study suggested that the body’s ECS affects sleep modulation (10) . Poor sleep quality can lower one’s immunity, affecting one’s vulnerability to common cold viruses (11) .
The ECS may also be connected to other bodily functions, such as heart rate, blood pressure, and energy metabolism (12) .
Why Are People Turning to CBD for Colds?
Inflammation that affects a person’s nose and throat in the upper respiratory tract causes the common cold (13) . Rhinoviruses most frequently cause the common cold (14) .
No cure exists for the common cold. Numerous people recover from it within ten days (15) . Natural remedies and over-the-counter (OTC) products are often used to manage symptoms of the common cold , such as sinus infections.
Common natural remedies include homemade chicken soup, which may help ease symptoms of respiratory tract infections, according to a 2000 study implemented by the University of Nebraska Medical Center (16) .
Research and Studies on CBD for Colds
Studies show that CBD has anti-inflammatory properties and analgesic propertie s (17) . It may benefit the common cold, which results from nose and throat inflammation and induces pain, such as headaches or sore throat.
A 2010 study administered by the National Institutes of Health (NIH) produced mixed results based on the particular virus es involved, Herpes Simplex Virus (HSV)-1 and HSV-2 (18) .
The researchers noted that cannabinoids may help with persistent viral infections. Cannabinoids are a specific group of chemical compounds that contain active components of the cannabis plant.
However, the researchers also noted that the chemical compounds may weaken a person’s natural immune function.
Individuals with cold or flu-like symptoms that believe their illness is more severe than the common cold or flu should seek medical attention immediately.
For example, while COVID-19 shares some symptoms with influenza, coronavirus disease is a severe respiratory illness that may require hospitalization (19) .
Pros and Cons: Can CBD Help with Colds?
- Studies show that CBD may improve sleep quality among people with anxiety problems (20) . People with poor sleep quality are more susceptible to the common cold (21) .
- CBD is not psychoactive, meaning CBD users do not experience mind-altering effects with CBD (22) .
- The United States Food and Drug Administration (FDA) promotes research on the possible medicinal uses of various cannabis strains (23) .
- No scientific evidence exists that CBD can directly reduce cold symptoms, such as a cough or runny nose.
- Vomiting and diarrhea are commonly observed side effects of CBD intake in humans (25) . People who experience these side effects should immediately see their doctor.
- The seizure medication Epidiolex is the only FDA-approved CBD product (26) .
Comparing CBD Oil and Alternative Treatments for Colds
Possible interventions to prevent the common cold include vitamin C, zinc, and probiotics (27) . These remedies may be alternatives to CBD products .
Data regarding vitamin C intake shows that the organic compound may lower the duration and severity of colds in study subjects (28) .
Zinc intake within 24 hours of the start of cold symptoms may reduce the severity and duration of colds in healthy human subjects (29) .
Studies show that probiotics may be beneficial in preventing upper respiratory tract infection (30) . Probiotics are live microorganisms with purported health benefits.
Cannabidiol similarly contains properties that may alleviate the common cold’s symptoms. Edible or topical CBD products infused with vitamin c, zinc, and probiotics may benefit individuals with colds.
How to Select the Right CBD for Colds
CBD comes in different types: CBD isolates, full-spectrum, and broad-spectrum.
Full-spectrum CBD contains all naturally occurring compounds found in cannabis plants. It has high levels of cannabidiol and trace amounts of tetrahydrocannabinol (THC), flavonoids (plant metabolites), terpenes (aromatic compounds), and other minerals.
Meanwhile, b road-spectrum CBD contains similar contents as full-spectrum without the psychoactive compound THC.
Finally, CBD isolates contain pure cannabidiol and are usually sold as powder or crystals.
Consumers should choose only CBD products with the best quality to maximize the compound’s health and wellness benefits.
When purchasing high-quality CBD, consider the following:
- Industrial hemp is high in fiber yet low in THC content (31) .
- CBD legality varies from state to state.
Medical marijuana is legal in most states, while others have passed laws legalizing CBD based on stipulations, including the form, THC level, and usage (32) .
- Each CBD product should include a certificate of analysis (COA). The COA shows that a third-party laboratory tested the product.
CBD Dosage for the Flu and Colds
The FDA has not officially approved a CBD dosage guide. Human clinical trials on CBD, however, may provide insight for safe and reliable CBD doses.
One study used a daily dose of CBD to treat anxiety, which produced sufficient clinical response (33) . CBD produced few reported side effects and was well tolerated.
A 2021 review reported that high doses of CBD up to 1,500 mg per day are well tolerated in human subjects (34) .
How to Take CBD Hemp Oil for Colds
Taking CBD hemp through tinctures allows people to measure the amount of cannabidiol they use.
CBD oil drops are put under the tongue using a dropper. The oil is held there for 30 to 60 seconds before swallowing.
Consuming CBD gummies, tablets, and capsules is another straightforward way to consume CBD. They also come in predetermined CBD doses for consumers’ convenience.
Vaping gets CBD into the system quickly. However, vaping is not a recommended form of CBD administration for colds.
A 2008 study showed that cigarette smoke could worsen viral infections, including influenza (35) .
What Are Colds and the Flu?
Colds and the flu are both classified as contagious respiratory illnesses caused by viruses. The influenza virus causes the flu, while several viruses can cause the common cold (36) .
Common flu symptoms indicating the effects of an immune response include (37) :
- Sore throat
- Stuffy nose or runny nose
- Body aches
The flu sometimes leads to influenza deaths. Experts estimate that the flu causes approximately 23,600 deaths in the United States every year (38) .
The flu and cold can also have similar symptoms, which can make it difficult to distinguish them. The flu is generally more severe than colds (39) .
How Do People Get Colds and the Flu?
The colds and the flu viruses can spread from person to person, often through the air. Infected individuals are contagious for several days after they have fallen ill.
One can catch viruses like influenza when someone near them is coughing or sneezing (40) .
Viruses continuously mutate to breach the body’s immune system’s defenses. Antibiotics designed for bacteria produce n o effect on viruses (41) .
Viruses ca n stay alive on hard, non-porous surfaces for 24 to 48 hours (42) . People can become infected by touching something the virus is on, like a phone, pen, or doorknob, and then touch their nose or mouth.
How Do Colds Impact Infected Individuals?
Viruses are microscopic infectious agents coated with thin layers of protein (43) .
The cold or flu viruses cannot reproduce by themselves. They use human cells to replicate themselves.
Once the virus infiltrates a human cell, it utilizes the cell to clone itself. After the cell breaks, the virus seeks a new cell or combines with the cell’s DNA.
The virus moves through the process of genetic duplication (mitosis) and cellular division (cytokinesis).
Why Let a Cold Run Its Course?
Viruses that produce colds and the flu affect weak cells with many toxins (44) . The body would prefer to rid itself of these cells in some ways.
A cold or the flu, however, is a natural event. It identifies, destroys, and eliminates damaged cells. Thus, one remedy is to let the cold run its course.
Common Flu Treatments
Flu vaccines develop antibodies two weeks after an individual is vaccinated (45) . The antibodies protect an individual from influenza infections.
Meanwhile, antiviral medications target a range of viruses, including influenza viruses (46) .
It is critical to wash one’s hands frequently during the flu season, especially before eating or touching the eyes, mouth, or nose. Avoiding sick people can also help stop the flu from spreading.
CBD may have antibacterial properties and anti-inflammatory effects and properties that may benefit individuals with colds (47) .
The chemical compound may help reduce chronic pain and inflammation (48) .
CBD studies conducted by organizations such as the University of Colorado yielded promising results (49) .
Still, researchers have conducted no direct studies on CBD and colds. People interested in trying CBD products for colds should first seek medical advice from a doctor.
CBD Oil for Colds: Does It Help With Flu Symptoms?
Following the famous quote from Game of Thrones, it’s time to prepare for the colds and flu season.
Very few people make it through the winter without an annoying sore throat or colds.
Sure, you can go down the conventional route, get some anti-cold medications or even a flu shot that is laden with unknown chemicals, but you may just as well turn to natural remedies for help.
What many doctors won’t tell you is that it’s best to support your natural immunity while letting colds and cases of flu run their course. Natural solutions include herbs, teas, vitamins, minerals, and plant-based extracts — such as CBD oil.
In this article, we shed some light on how to use CBD to boost your immune system, preventing your body from catching infections.
CBD for Colds: Does It Help?
The common cold is triggered by inflammation that occurs in a person’s nasal and upper respiratory tract. Although many viruses can cause a cold or flu, rhinoviruses are to blame most of the time.
Experiencing a sore throat, congestion, runny nose, cough, sneezing, mild fever, headaches, and body aches, are some of the most common symptoms of colds.
There is no known cure for colds, but most cases go away within two weeks when a person uses natural remedies to control symptoms.
CBD (cannabidiol) has demonstrated antibacterial and antiviral properties in many studies — showing itself as a potential therapeutic agent for colds.
Scientists found that CBD has anti-inflammatory and analgesic properties. Together with another major compound, THC (tetrahydrocannabinol), it can be found in Sativex, a mouth spray used to relieve pain and spasticity.
One study concluded that CBD was able to improve the quality of sleep in patients with anxiety disorders.
Poor sleep is often associated with susceptibility to the common cold. According to one study, people with low-quality sleep are more prone to getting sick upon exposure to rhinoviruses.
Despite positive initial findings, there’s no direct scientific evidence to prove that CBD can cure colds.
How CBD Oil Works to Help with Colds
Researchers have found that CBD interacts with receptors of the endocannabinoid system (ECS), a major regulatory network that modulates several vital functions throughout the body.
CBD’s relationship with the ECS is believed to be the reason for its immunosuppressant effects. Using this mechanism, CBD can improve the communication between the immune cells and selectively shut down overactive parts of the immune system — reducing inflammation.
In a 2008 study, CBD was found to modulate sleep-wake cycles through its interaction with the ECS.
The sleep-wake cycle can be modulated through the activation of the CB1 receptor. While CBD doesn’t directly bind to CB1, it signals the ECS to produce more endocannabinoids that activate it; it also slows down their breakdown, so in the end, more endocannabinoids can bind to CB1 receptors and contribute to a more restful sleep.
CBD activates the CB2 receptor, which, according to a study on respiratory viral infection, is responsible for anti-inflammatory effects in the body.
Why Is It Worth to Use CBD Oil for Colds?
- According to the aforementioned studies, CBD might benefit people with colds and flu due to its ability to reduce symptoms of the illness, such as inflammation and pain. in anxiety patients. Poor quality sleep is linked to a weakened immune system and a higher susceptibility to infections.
- Unlike THC, the intoxicating ingredient in medical cannabis, CBD doesn’t have mind-altering effects, so it won’t affect your daily performance.
- CBD is legal in the USA. You can purchase it without prescription in CBD stores near you or online.
- The FDA supports research on the potential therapeutic properties of cannabis plants and their derivatives.
What Are the Limitations of Using CBD Oil for Colds?
- No study has yet examined a direct link between CBD use and the symptoms of colds and flu.
- Despite its excellent safety profile, CBD can have some mild side effects in high doses. In humans, the observed adverse effects include diarrhea, dry mouth, dizziness, and changes in appetite.
- The CBD market isn’t regulated, so CBD products lack standardization and come with a high risk of mislabeling.
- Currently, the only FDA-approved medication from CBD is Epidiolex — an antiepileptic drug based on a synthetic version of CBD isolate. There are no other official marketing applications for CBD.
CBD vs Other Natural Treatments for Colds
Vitamin C, probiotics, and zinc are often mentioned as potential preventive and interventional methods for the common cold.
Data on Vitamin C shows that the compound can cause a decrease in the duration of colds in subjects.
Zinc intake within 24 hours of symptom onset was found to mitigate the severity of flu symptoms and colds in participants.
Probiotics are beneficial in protecting your system against upper respiratory tract infections due to their antiviral properties.
Taken together with these aforementioned compounds, CBD can work with them in a synergy, enhancing the efficacy of your cold treatment.
You can also find many CBD products today that are infused with vitamin C, probiotics, and zinc.
How to Choose CBD for Colds
There are three main types of CBD when it comes to common colds: full-spectrum, broad-spectrum, and CBD isolate.
The most desired type is the full-spectrum option. Such products contain all of the naturally occurring compounds found in hemp — including CBD, adjunctive cannabinoids, terpenes, and trace amounts of THC.
Full-spectrum CBD creates the entourage effect, which refers to the synergistic effects achieved by the aforementioned compounds. The entourage effect makes whole-plant extracts more effective and predictable when it comes to dosing.
Broad-spectrum CBD is much like its full-spectrum counterpart, except for the lack of THC. The intoxicating cannabinoid is removed after initial extraction to create a zero-THC product that still benefits from some parts of the entourage effect.
Finally, CBD isolate refers to pure CBD, which has been isolated from other hemp compounds and turned into whitish crystals. These crystals are then powdered and infused into a range of CBD products, such as oils, edibles, capsules, vapes, and topicals. Although isolates carry the highest dose of CBD per serving, they don’t evoke the entourage effect — making them the least desired option.
Tips for Finding the Right CBD Oil:
- Look for a certificate of analysis of the desired CBD product. This is a form of a lab report that shows the results for the product’s potency and purity.
- Choose high potency CBD oils derived from organic hemp. Such plants are grown in natural conditions, without pesticides and artificial boosters, so they’re cleaner and contain higher concentrations of CBD than mass-produced hemp.
- Opt for CO2-extracted products. CO2 extraction is the industry’s golden standard; it doesn’t require adding extra heat or toxic solvents and ensures the highest purity and consistency in potency in all product batches.
- Purchase products with targeted formulas. As mentioned, CBD oil can be infused with other complementary compounds, such as vitamin C, vitamin D, probiotics, and zinc.
- Consult a doctor experienced in cannabis use before purchasing CBD. Doing so will help you determine the right dosage and avoid potential interactions with other medications.
CBD Dosage for Colds
Since CBD products aren’t regulated in the USA, there are no official guides or charts for CBD dosage.
However, taking a look at human clinical trials using CBD may provide insight for a safe and relatively accurate CBD dosage range.
For example, using CBD for anxiety may require doses between 25–175 mg per day of CBD. These amounts are enough to produce a significant clinical response. However, the study’s authors used pure CBD, not a whole-plant extract, so the dosage may change depending on what kind of product you’re using.
CBD is also safe and well-tolerated in humans. Studies have shown that doses of CBD can reach as high as 1,500 mg per day without any dangerous side effects.
How to Take CBD Oil for Colds
The best way to take CBD for cold and sore throat is through oil or tincture. CBD oils are usually administered sublingually (under the tongue) and held there for up to 60 seconds.
You can also take CBD directly — as gummies or capsules — which is a great way to use CBD for beginners. That’s because they’re straightforward and contain a premeasured amount of CBD.
Vaping is another way to get CBD into your system. It offers the highest bioavailability and the fastest onset of effects. However, this form of consumption may not be recommended if you cough because it can irritate your airways, causing more cough, sore throat, and sneezing.
Why Do We Get Colds and Flus?
This is actually a quite difficult question to answer, but most of the time, it boils down to the following triggers:
- Being constantly in confined areas with other infected people who have influenza. Viruses become airborne when someone coughs, so it can only take a few breaths to catch the illness.
- Constant mutations of rhinoviruses. Unfortunately, our immune systems need some time to adjust to these ever-changing germs, and catching a cold or flu is actually a sign of a “system upgrade.”
- Touching items that have been touched by an infected person. Viruses can survive on non-porous surfaces for hours, so it’s possible to get sick by getting a second-hand infection.
How do Viruses Affect Our Body?
Colds and cases of flu are simply the outcomes of viruses attacking our bodies. Viruses are microscopic molecules of genetic material, covered by a thin layer of protein. Unlike the normal cells in our body, these viruses aren’t able to reproduce on their own, instead, they use the metabolism of your cells to produce many clones of themselves.
When a virus enters a cell, it will either use its constituents to copy itself, eventually breaking the cell seeking a new one, or, injecting itself into the DNA of your cell. By doing so, the virus can pass down through natural cell division (cytokinesis) and genetic duplication (mitosis).
Key Takeaways on Using CBD Oil for Colds
CBD has remarkable anti-inflammatory and anti-viral properties that may prove beneficial for individuals with a common cold or flu.
The cannabinoid interacts with various receptors of the ECS, which improve its ability to regulate immune response — enhancing your immunity as a result.
Not only that, but CBD can also curb inflammation and pain, which are the two common symptoms of a cold. On top of that, it can also help improve sleep in people with anxiety. Poor sleep is one of the major reasons why people have compromised immune systems.
You can add some zinc, probiotics, and vitamin C to your daily routine as preventive measures against colds. Holistic supplementation will help enhance your immune system and keep you resistant to illnesses.
