Can CBD Help with Sore Throat? CBD may be a potential treatment for sore throat due to its reported antibacterial and anti-inflammatory properties. CBD oil can be a promising treatment for sore throat and other flu-like symptoms due to its potential antibacterial and anti-inflammatory properties.
CBD Oil for Sore Throat – August 2022
Cannabidiol (CBD ) could be a potentially effective treatment for sore throat due to its supposed health benefits .
CBD is a chemical substance that can be obtained from cannabis strains, such as hemp plants .
In clinical trials, cannabidiol was found to exert antibacterial , anti-inflammatory , and antioxidant properties (4) . Researchers even assumed that the antibacterial activity of hemp essential oils is perhaps due to the CBD content.
A study published in Frontiers in Cellular and Infection Microbiology revealed that CBD acts as a novel modulator of bacterial membrane vesicles (5) .
Cannabidiol reportedly increased the bactericidal action of several antibiotics and also the antibiotic effects of kanamycin against Gram-positive bacteria. Kanamycin is an antibiotic used in treating a wide range of infections.
The study’s authors concluded that the compound might be used with specific antibiotic drugs as a potential agent to enhance antibacterial activity and reduce antibiotic resistance (6) .
In another study, researchers learned that cannabidiol acted as a useful helper compound when combined with bacitracin to kill Gram-positive bacteria (7) . Bacitracin is an antibiotic ointment used to help prevent minor skin infections.
Infection with specific Gram-positive bacteria can result in a sore throat (8) .
Although these studies suggest that CBD may benefit patients with a sore throat , no direct or human (clinical) evidence exists to prove that CBD can effectively treat the condition.
How CBD Oil Works to Help with Sore Throat
There is a lack of scientific information on how CBD exerts its supposed antimicrobial effects.
However, the compound is known to engage with both CB1 and CB2 cannabinoid receptors of the endocannabinoid system (ECS) (9) .
The ECS is a part of the body that regulates certain functions, such as the immune system and central nervous system. Its contribution to regulating various bodily processes makes it an attractive therapeutic target for many medical fields, including studies on antibacterial activity (10) .
The CB2 receptors are primarily involved in immunosuppressive and anti-inflammatory actions (11) . Activation of these receptors is believed to bring about these therapeutic benefits.
The Pros and Cons of CBD Oil for Sore Throat
- Studies have shown that CBD may have some antibacterial , anti-inflammatory , and antioxidant properties (12) that theoretically could benefit a person with a sore throat , yet unproven.
- In another study, cannabidiol was found to increase the antibacterial activity of specific antibiotic drugs (13) . Researchers also learned that CBD acted as a capable helper compound with bacitracin in killing Gram-positive bacteria (14) .
- Selling, transporting, and possessing cannabidiol is now legal, so long as the compound has been extracted from hemp plants in a manner compliant with the 2018 Farm Bill. Even the transportation of these specific, hemp-derived products is now allowed across state lines (15) . However, you should always check your local and state laws before transporting CBD or any cannabinoid as some exceptions may apply .
- Research on the potential medicinal uses of cannabis plants and its derivatives is supported by the United States Food and Drug Administration ( FDA ) (16) .
- CBD is a non- psychoactive compound of cannabis, unlike tetrahydrocannabinol ( THC ). Although both are present in marijuana, it is the THC content that causes the mind-altering effects.
- There is a distinct lack of clinical data to prove that CBD could treat a sore throat.
- Although it does not cause a sore throat , using CBD can lead to side effects , such as dry mouth , drowsiness, reduced appetite, diarrhea, and fatigue (17) .
- Apart from Epidiolex, a CBD drug used to treat epilepsy, no other marketing application for cannabidiol has been approved by the FDA (18) .
- A lack of standardization in the CBD industry has led many brands to inaccurately label their cannabidiol products, especially those sold on the internet (19) .
- Health insurance providers do not cover the use of CBD products as part of their plans.
How CBD Oil Compares to Alternative Treatments for Sore Throat
Sage, thyme, and barberry are believed to have antibacterial properties that can counteract bacteria that cause sore throat (20) .
In a clinical trial, a combination treatment of sage and echinacea reportedly exhibited similar efficacy to chlorhexidine and lidocaine treatment in reducing symptoms of a sore throat (21) .
Chlorhexidine is an antiseptic used to disinfect the skin before surgery, while lidocaine works as a local anesthetic.
Thyme essential oil was found to exhibit antibacterial activity against Streptococcus pyogenes, a type of bacteria that can cause sore throat (22) .
Meanwhile, ethanol and aqueous extracts of barberry exhibited anti-inflammatory properties (23) that may be used to create health products for soothing sore throats .
In comparison, cannabidiol is believed to have properties that may help with a sore throat .
CBD also has anti-inflammatory effects (24) similar to the essential oil extracted from thyme.
How to Choose the Right CBD for Sore Throat
To choose the right cannabidiol product for sore throat , users must know the various types of CBD available today.
The three forms of CBD are full-spectrum , broad-spectrum, and isolate.
Full-spectrum is the type of cannabidiol that has all of the cannabinoids and other natural compounds of Cannabis sativa plants. It comes with flavonoids, terpenes , and THC .
High-quality full-spectrum CBD products are rich in cannabidiol while having small amounts of the other substances present.
The next type is known as broad-spectrum, a form of CBD that is similar to full-spectrum . Its primary difference is that it does not have tetrahydrocannabinol included.
Since THC is psychotropic, some people prefer not to use products that have it. Those who also want to benefit from all of the cannabis compounds except for THC often choose broad-spectrum.
The last type of CBD is called isolate. CBD isolates are made of pure cannabidiol and are typically found in crystalline form.
CBD isolates do not have a distinct taste or smell because of their purity.
Of the three, full-spectrum cannabidiol is perhaps the most potent form of CBD available. It is known for the synergism known as the “entourage effect.”
This effect is a proposed action wherein all cannabis constituents work more efficiently when consumed together (25) .
Full-spectrum CBD oil could be an ideal option for treating sore throat .
No matter the form of cannabidiol desired, it is best to select high-quality products all the time to maximize the benefits of CBD .
Here are the following tips to help users choose the best CBD oil products for sore throat :
- Acquire the certificate of analysis (COA) of the selected CBD product . This document provides an analysis report showing that the item has undergone proper testing and contains the specifications listed on its label.
- The best source for cannabidiol is industrial hemp. Buy from CBD brands that use organic hemp for their products.
- Make sure to read product and shop reviews before buying from an online CBD store. When purchasing from a dispensary , ensure that the establishment is authorized to sell cannabidiol .
- Be knowledgeable of the legalities concerning CBD use in various states. Although CBD is currently legal, the laws surrounding its use may change at any time.
- Talk to a medical professional, preferably someone knowledgeable with medical cannabis , before purchasing or using any CBD product .
CBD Dosage for Sore Throat
There is no official guide on CBD dosage for sore throat that has been approved by the FDA .
However, one can look at past clinical trials on human subjects to find a dose range that is safe and reliable.
In 2019, The Permanente Journal published a study on anxiety where patients took 25 mg to 175 mg of CBD per day (26) . Besides eliciting an adequate clinical response, the compound was reportedly well-tolerated by the subjects, and the side effects were minimal.
A review in 2017 mentioned that humans could take as much as 1,500 mg of CBD per day. Its authors also noted that none of the studies that were assessed reported tolerance to cannabidiol (27) .
How to Take CBD Oil for Sore Throat
Taking CBD hemp oil by using tinctures is a quick way of applying the compound when needed. These products usually come with droppers that make the mixture easy to administer under the tongue.
A straightforward approach is by consuming CBD in the form of gummies , cookies, capsules, and tablets. Edibles can be eaten like snacks, while capsules and tablets can be administered orally similar to dietary supplements .
Although vaping may be a quick way of getting cannabidiol in the system, it is not a recommended way of administering CBD for sore throat .
Smoking cannabis or using CBD vape devices can worsen one’s condition, primarily because the two are often associated with lung problems (28) .
What Is a Sore Throat ?
A sore throat , also called pharyngitis , is the feeling of pain, irritation, or scratchiness of the throat that could get worse when swallowing.
Viral infections (the common cold or flu) are the most common causes of a sore throat . It can also be a result of irritants, like chemicals or tobacco smoke.
Streptococcal pharyngitis ( strep throat ) is a unique and less common type of sore throat caused by bacteria. It often requires treatment using antibiotics to prevent further complications (29) .
A sore throat can have varying symptoms depending on its cause. These include:
- Difficulty in swallowing
- Scratchy or painful sensation in the throat
- Worsening pain when talking or swallowing
- Swollen glands by the jaw or neck
- Red and swollen tonsils
- A muffled or hoarse voice
- Presence of pus or white patches on the tonsils
Infections that cause a sore throat may also result in other symptoms, such as:
- Runny nose
- Body aches
- Vomiting or nausea
The following are some risk factors that can make a person more susceptible to a sore throat :
- Age – Children ages three to fifteen years old are more likely to catch strep throat .
- Allergies – Ongoing allergic reactions to molds, dust, or pet dander and seasonal allergies increase the likelihood that a person develops a sore throat .
- Frequent sinus infections – Drainage from the nose can irritate the throat or spread viral diseases.
- Weak immune system – A person is more susceptible to viral infections if their immune response is low.
- Close quarters – Viruses and bacteria can quickly spread in places where people gather, especially in confined spaces.
- Exposure to chemicals or smoking – Particles in the air coming from household chemicals and burning offal fuels can lead to throat irritation. Smoking also lowers immunity and predisposes people to sinus infections in general.
How Is a Sore Throat Treated?
A doctor determines the type of sore throat a person has by first asking them about their symptoms. They also perform a physical examination and may sometimes carry out a swab test on the throat.
Since bacteria cause strep throat , antibiotics are required to get rid of an infection while preventing rheumatic fever and other conditions.
People who have strep throat should stay home from school or work until their fever subsides. They must also have taken antibiotics for a minimum of twenty-four hours.
However, antibiotics do not work against pharyngitis caused by cold viruses . A sore throat due to viral infection typically gets better within a week (30) .
The following are tips that can help alleviate symptoms of a sore throat :
- Gargling with warm salt water several times a day
- Drinking a glass of water containing lemon tea with honey
- Eating lozenges or candies that can stimulate saliva production
- Using a humidifier or cool-mist vaporizer to moisten the air and help soothe a dry throat
- Taking over-the-counter pain medication, such as ibuprofen
The anti-inflammatory effects of CBD may be useful against viral infections that can lead to a sore throat .
According to studies, cannabidiol has been found to exert antibacterial , anti-inflammatory , and antioxidant properties that could help with sore throat symptoms.
CBD is also thought to interact with various receptors in the body to bring about its supposed therapeutic effects.
However, the lack of scientific evidence makes it difficult to prove that CBD is an effective treatment for sore throat .
Cannabidiol is not known to irritate the throat, but it can have adverse effects upon consumption. Studies have often reported side effects , including dry mouth , drowsiness, and diarrhea.
Unlike THC , CBD is a non- psychoactive compound that does not cause mind-altering effects when taken.
Still, a person should consult a doctor before deciding to use any CBD product for their condition. An expert who is experienced with medical marijuana is recommended.
Always consult a licensed healthcare professional for treatment of a sore throat or any other health concern.
CBD Oil for Sore Throat: How Does It Relieve Flu Symptoms?
Autumn and winter are very beautiful seasons, but at the same time, the low temperatures, harsh winds, and humid weather can cause many health problems, especially as our immune system is more susceptible to different viruses and bacteria.
Sore throat, flu, coughing, and congested nose are all typical symptoms of getting an infection due to a weakened immune system.
Sore throat is a common symptom people are dealing with during winter, so you’re probably wondering if there’s anything you can do to prevent it or get rid of it?
Can you use CBD oil, the major non-intoxicating ingredient in cannabis plants and a well-known anti-inflammatory, to help with a sore throat and other flu-like symptoms?
What Causes Sore Throat?
A sore throat is usually a symptom of the flu or cold. Sometimes, it can be caused by smoking tobacco, but most of the time, it stems from viral and bacterial infections.
Sore throats triggered by viruses often involve other symptoms, such as red eyes, mild headache, fever, runny nose, sneezing, coughing, or congestion of the airways.
Other potential causes of cold are allergies, air pollutants, and air dryness.
To relieve sore throats, people usually take anti-inflammatory drugs or pain relievers, such as naproxen or ibuprofen. These medications provide short-term relief from pains of flu and sore throat.
CBD also has remarkable pain-killing properties, but at the same time, it doesn’t involve the dangerous side effects associated with the long-term use of conventional anti-inflammatory drugs.
So, when you take CBD, you may expect a feeling of ease in your throat — which may help you to deal with flu symptoms.
Can CBD Help with Sore Throat?
The supposed health benefits of CBD make it a potentially effective treatment for sore throat.
CBD is a cannabis-derived compound; unlike THC, it won’t get you high because it doesn’t have intoxicating properties. Instead, CBD modulates a very important system in your body known as the endocannabinoid system (ECS) — the number one reason for its therapeutic versatility.
In clinical human trials, CBD has demonstrated antioxidant, anti-inflammatory, and antibacterial properties. Researchers even theorized that the antibacterial activity of essential oils in hemp is due to the presence of CBD.
In a study published in Frontiers in Cellular Infection Microbiology, the authors revealed that CBD modulated bacterial membrane vesicles.
CBD increased the bactericidal activity of several antibiotics against Gram-positive bacteria. The research team also noted that CBD can be used with specific antibiotics as a potential enhancing agent to reduce antibiotic resistance.
Another study that tested the efficacy of CBD against Gram-positive bacteria concluded that the compound had remarkable antibacterial effects in a combination with an antibiotic ointment.
Gram-positive bacteria are known to cause a sore throat.
Although these studies suggest that CBD may be beneficial for patients with sore throats, we still need more direct clinical evidence to prove CBD’s efficacy in the long run.
CBD for Sore Throat Pain
CBD is generally used to treat anxiety, depression, sleep disorders, and pain.
On top of its antibacterial properties, CBD can also reduce inflammation and alter pain signaling to the brain.
In a 2010 review of the existing studies, CBD and other cannabinoids have been mentioned as novel anti-inflammatory drugs.
CBD activates the CB2 cannabinoid receptor in the ECS, which is mostly found in the immune system and peripheral organs. This interaction causes CBD to inhibit the release of cytokines, which are pro-inflammatory proteins that cause redness, swelling, and pain upon activation.
When it comes to pain, CBD uses a multifaceted mechanism.
First, it helps to increase the body’s natural levels of anandamide, which is one of the two endocannabinoids produced by the body. Anandamide is responsible for modulating our pain threshold on top of many other functions (appetite, fertility, fear, pleasure, etc.)
Another way CBD can mitigate pain is through its interaction with the TRPV1 vanilloid receptor. This receptor controls communication between nerve cells and the brain — including the way pain signals are transmitted. The activation of the TRPV1 receptor leads to dampened sensations of pain.
CBD for Strep Throat
Strep throat occurs when a sore throat is accompanied by fever caused by streptococcal infections.
You can find many testimonies online from people sharing their success stories using CBD oil for strep throat.
According to our findings, it’s only within reason to assume that CBD oil can cause some dryness in your mouth if you take it without water, but it doesn’t contribute to strep throat.
There are no direct studies that would evaluate CBD’s efficacy for strep throat, but considering its anti-inflammatory and antibacterial properties, it can help with the treatment of minor bacterial infections.
But most importantly, CBD is an effective pain killer — so it can definitely help with some pain associated with strep throat.
How does CBD Oil Work to Help with Sore Throat?
Researchers have yet to understand the mechanism behind CBD’s supposed antibacterial properties. However, the compound is known to interact with the receptors of the endocannabinoid system (ECS).
The ECS is a vital network in the body that regulates essential physiological functions, such as cognition, immune response, pain signaling, body temperature, sleep cycles, appetite, fertility, mood, memory, and more.
The CB2 receptors are primarily responsible for immunosuppressive and anti-inflammatory actions. CBD activates these receptors, which is believed to be the main reason behind its therapeutic benefits.
Why You Should Consider Using CBD for Sore Throat
- Numerous studies have shown that CBD exerts antibacterial, anti-inflammatory, and antioxidant actions in the body, which could theoretically benefit people with a sore throat.
- CBD can increase the antibacterial activity of certain antibiotics. Researchers also learned that CBD can be of assistance in killing Gram-positive bacteria.
- CBD is legal on a federal level as long as the products are compliant with the 2018 Farm Bill. The new law allows for the selling, transporting, and processing of CBD as long as it is derived from hemp and contains no more than 0.3% of THC.
- The FDA supports research on the potential medicinal applications of cannabis plants and their derivatives.
- CBD is non-intoxicating, unlike THC, so it won’t produce any mind-altering effects.
CBD’s Limitations for Sore Throat
- There is no clinical data that could prove CBD’s efficacy in treating a sore throat.
- Although CBD doesn’t cause a sore throat, it still has some benign side effects, such as dry mouth, reduced appetite, fatigue, drowsiness, and diarrhea if you take large doses.
- CBD isn’t approved as an official treatment for any medical condition aside from epilepsy and multiple sclerosis.
- There are no standards in place when it comes to manufacturing and labeling practices among CBD producers. A lot of CBD products sold locally and online are mislabeled or contaminated with toxic ingredients. in the United States.
How to Choose the Right CBD Oil for Sore Throat?
You can choose between three forms of CBD: full-spectrum, broad-spectrum, and isolate.
The full-spectrum form of CBD contains all of the cannabinoids, terpenes, and flavonoids from the cannabis plant. These compounds work synergistically to improve the therapeutic profile of CBD. This mechanism is known as the entourage effect.
High-quality full-spectrum CBD oils are rich in CBD and only have a trace amount of THC and other cannabinoids.
The second type is broad-spectrum CBD, a form that is similar to full-spectrum. The main difference is the lack of THC, which is removed once the above compounds have been extracted from the plant matter.
Broad-spectrum CBD is a good option for people who want to benefit from cannabidiol but are afraid of taking any amounts of THC.
If you’re allergic to other hemp compounds, such as terpenes, waxes, and oils, you can try CBD isolate. This form of CBD contains pure CBD and carries the highest dose per serving; it’s also odorless and flavorless, which is another point in favor of isolate-based CBD oils.
That being said, isolates don’t evoke the entourage effect, making them less desired than full-spectrum and broad-spectrum CBD products.
Tips for Choosing High-Quality CBD Oils
- Only purchase from reputable companies that can deliver relevant certificates of analysis (COA) of the chosen product. This document will list the entire phytochemical profile of the tested sample, including its CBD content, THC levels, and results for contaminants.
- The best CBD oils for sore throat are made from industrial hemp. Choose brands that use organic hemp plants for extraction.
- Make sure to read product reviews before buying from an online vendor. When purchasing CBD oil for sore from a dispensary, check if the store is authorized to sell CBD products.
- Choose CO2-extracted CBD oils. This extraction method is the industry’s golden standard because it yields pure and potent extracts without using extra heat or aggressive solvents.
- Consult a holistic doctor experienced in CBD and cannabis use before purchasing or using any CBD product. Doing so will help you find the right dosage and avoid negative interactions with medications.
CBD Dosage for Sore Throat
Since CBD isn’t regulated by the FDA, there are no official dosage guidelines or charts when it comes to using CBD for sore throat.
However, you can take a look at past studies on humans to find what dosages work best that was found to be safe and effective.
A 2019 study from the Permanente Journal revealed that people with anxiety took 25 mg to 175 mg of CBD per day — effectively reducing anxiety while being well-tolerated by the subjects.
A 2017 review of the existing scientific literature concluded that humans could take CBD in doses as high as 1,500 mg per day. The authors also noted that none of the studies that were examined reported increased tolerance to CBD.
How to Take CBD Oil for Sore Throat?
The best way to take CBD for sore throat is through oil or tinctures.
CBD oil is administered under the tongue using a dropper. You need to hold it in your mouth for up to 60 seconds for improved absorption. From there, the CBD will travel directly to your bloodstream, avoiding the first-pass metabolism in the liver.
Another straightforward approach to taking CBD is through eating flavorful edible gummies or taking capsules. Edibles can be eaten like normal snacks, while capsules can be administered similarly to other health supplements. They take more time to kick in — up to 90 minutes — but the effects last longer than with other methods.
Although vaping may be a fast and effective way to administer CBD to your system, it’s not the best way of taking CBD for sore throat. The vapor can be too hot and further irritate your throat.
Does CBD Oil Have Side Effects?
Yes, just like all health supplements out there.
CBD has many health benefits and an excellent safety profile. It can’t cause a lethal overdose and doesn’t involve dangerous side effects with long-term use but it still has some benign side effects.
That being said, where there is a plus, there is also a minus.
CBD can cause the following side effects:
- Dry mouth
- Appetite fluctuation
- Diarrhea (doses over 300 mg)
CBD can also disrupt your liver’s ability to metabolize drugs because it’s a potent inhibitor of the Cytochrome P450 system (CYP450). This system is responsible for metabolizing 60% of pharmaceutical drugs. A similar inhibitory effect is achieved by drinking grapefruit juice, so if your medication has a grapefruit warning on it, you shouldn’t take it at the same time you take CBD.
The best way to avoid these drug interactions with CBD is to consult a doctor before buying CBD for a sore throat.
Can CBD Oil Make Your Throat Dry?
As mentioned earlier in the article, the ECS and its receptors occur throughout the entire body — including your mouth.
And your salivary glands.
When you take CBD oil under the tongue, it interacts with the cannabinoid receptors in the salivary glands, inhibiting saliva production.
That’s why you get the cottonmouth effect every single time you consume a cannabis-derived product.
It doesn’t matter whether you take CBD or THC — dry mouth knows no exceptions.
You can easily manage this side effect by keeping yourself hydrated before, during, and after your CBD use. If you already have a dry throat, CBD oil might cause some mild irritation, but it shouldn’t deteriorate your condition either.
Key Takeaways: Is CBD Oil Good for Sore Throat?
Although CBD oil isn’t a miracle cure for all your health problems, taking it for sore throat is well backed by science.
Several high-quality studies have highlighted CBD’s anti-inflammatory, antioxidant, and antibacterial effects — so it’s safe to assume you can use it to manage sore throat and other symptoms of flu and common colds.
CBD can also reduce the pain experienced by patients with sore throats. While no direct study has yet investigated its impact on this condition, current findings leave no doubt that it can be a decent approach to fighting infections and the side effects of a sore throat.
If you’re considering adding CBD oil to your medicine cabinet, make sure to consult a holistic doctor, especially if you take any medications that could interact with cannabidiol and cause unwanted reactions.
