Have you ever dealt with allergies? If so, you would know how difficult allergies can make your life. It can make your eyes watery and itchy, and that uncontrollable runny nose, coughing, or constant sneezing can truly make life difficult. Fortunately, CBD might be able to help you with that.

Let us take an in-depth look into how you can use CBD for allergies.

Causes of allergies

Some of the common environmental allergens are:

  • Dust mites and pet dander;
  • Mold and pollen;
  • Cigarette smoke;
  • Certain proteins in food.

In most cases, the symptoms deteriorate during certain seasons like spring. During spring, trees and flowers start to produce pollen when they’re blooming and these are termed seasonal allergies.

Another type of allergy that people experience is associated with food. Some people experience allergic reactions to certain types of food. In this case, the body’s immune system recognizes neutral proteins as enemies and makes an attempt to fight them. Quite similar to seasonal allergies, the symptoms may include coughing, inflammation, redness, and itching.

Symptoms of allergies

A hyperactive immune system starts to release various chemicals like histamine and other compounds. These compounds trigger the allergy symptoms that are experienced by most people. The symptoms of allergies are:

  • Headaches;
  • Coughing and sneezing;
  • Itching;
  • Wheezing;
  • Fatigue;
  • Nasal congestion and runny nose.

People with asthma require medical attention as allergy symptoms lead to worsening their breathing. Also, food allergies can be quite deadly as it can send your body to anaphylactic shock. If immediate help is not received, a person may suffocate and it can be fatal.

Severe allergies can be fatal. It can also make many chronic conditions more severe for the sufferer, such as eczema, COPD, rhinitis, asthma, and autoimmune disease. While there are quite a few over-the-counter medications available on the market for common allergies, research suggests that CBD for allergies is a much safer and more effective option.

How Does CBD Oil Help With Allergies?

The body is encouraged to produce more cannabinoids by CBD oil. Also, CBD helps the body in maintaining optimal levels of cannabinoids. These cannabinoids help in influencing an extensive range of biological functions including the body’s immune response.

CBD oil can help your body deal with allergies in the following ways:

  • CBD oil helps to strengthen the immune system – Allergic reactions are not something that happens out of the blue. They typically develop after your immune system has been exposed to allergens for several months or years. If your immune system is healthy, you are less likely to act out to eradicate the falsely detected enemies or irritants. When you take CBD oil for allergies, you are stimulating the endocannabinoid system in your body to enhance the functioning of your immune system. CBD is capable of interacting with the immune cells in your body through the cannabinoid receptors and this will result in strengthening your immune system.
  • CBD is an antimicrobial agent – Are you prone to infections? If so, you might be living in an environment that is filled with allergens. Terpenes and CBD in full-spectrum CBD oil are well-known for having antimicrobial properties, and therefore, CBD oil can be used to combat allergies and prevent allergic reactions. This is particularly possible because CBD oil helps in aiding your body in fighting off the infection instead of simply attempting to get rid of falsely identified enemies.
  • CBD oil has amazing anti-inflammatory properties – Due to its anti-inflammatory properties, CBD oil is widely popular. The main cause of allergy is inflammation and this contributes to aches, puffiness, and soreness that you might be experiencing during allergy season. CBD for allergies address inflammation and this results in reducing discomfort.
  • CBD helps in reducing stress – Both seasonal and food allergies can be quite annoying. It can be mentally and physically stressful. If your body or mind is under an increased amount of stress, your allergy symptoms can worsen. Marijuana helps allergies by reducing your stress.

If you were wondering can CBD help with allergies, this is how it can help you. To know more, check out our reviews and also find a list of the top 10 CBD oil that you can use for allergies.

CBD For Seasonal and Food Allergies

Take a look at how CBD oil helps with different types of allergies.

Seasonal allergies

A lot of people are using CBD for seasonal allergies because CBD helps in eliminating the side-effects of allergies caused due to seasonal allergens. Full-spectrum CBD oil is known to reduce pressure in the nasal cavities by opening up sinuses. It helps to prevent congestion. Inflammation in the sinuses and throats is caused due to seasonal allergies and it might make it difficult for you to talk, drink, eat, and breathe without irritation. As per studies, taking CBD oil might help in reducing the symptoms of seasonal allergies.

Food allergies

Food allergies can be avoided if you stop consuming the items that cause an allergic reaction. But, if you accidentally happen to consume the food items that you are allergic to, you might experience hives, tingling in the mouth, and swelling of the lips. You may even experience itching and shortness of breath. However, you mustn’t take food allergies lightly because it might lead to anaphylaxis. This is a condition that is life-threatening and it can rapidly progress. If you do experience anaphylaxis, you will require immediate medical attention.

However, for regular food allergic reactions like inflammation, swelling in the throat, itching, and headaches, you can use CBD oil for food allergies. Since CBD oil has wonderful anti-inflammatory properties, it can tackle your allergic symptoms and also promote a healthier immune system. Moreover, CBD helps to mitigate pain signals and also reduces physical discomfort.

How to Use CBD Oil?

If you are thinking of trying out the cannabis allergy treatment, including CBD oil as a part of your daily self-care routine. There are a few different forms of CBD that you can use to combat allergies.

  • CBD oil – This is the most versatile and common way of consuming CBD. It contains hemp extract that is suspended in a carrier oil for higher absorption and easier dosing. You can use a dropper to draw out your preferred amount of CBD oil and place it under your tongue for about 1 minute before swallowing.
  • CBD capsules – If you do not like the flavor of CBD oil, you can try CBD capsules. These capsules contain a pre-meditated CBD dosage per serving. CBD oil capsules can be taken anywhere and there’s no hassle of measuring the dose. – Gummies and other CBD products are becoming extremely popular because they’re easy to consume and are available in myriad flavors. These edibles come in various sizes, shapes, flavors, and formulas. – If you need fast relief from your allergies, vaping CBD would be up your alley. Simply load your vape pen with CBD e-liquid and puff it when you need it.
  • CBD topicals – CBD topicals are good for treating visible symptoms of allergies like swelling, redness, and skin irritation. You have to apply it directly onto the affected body part and gently massage it so that it is quickly absorbed in your skin.


If you want to use CBD for your allergies, you are recommended to use it as a part of your daily routine. Think of CBD oil as a preventive measure because this isn’t a cure for your allergies. It can only help to alleviate the symptoms of your allergies and provide you relief.

As for the recommended CBD dosage, you need to start slow. See how your body reacts to CBD and you can increase the dosage accordingly.

So, now that you have an understanding of how you can use CBD for your allergies, it is important to remember that CBD oil is not a cure. CBD helps in reducing or may even prevent the symptoms that are associated with allergies. As the available information regarding the use of CBD for allergies is still scarce, we recommend that you consult a healthcare professional before you start consuming CBD oil. This is particularly needed if you are already taking supplements or some kind of medication for allergies or other health conditions.

Take a look at our top 10 list of the best CBD oil for allergies and choose the one that is right for you.

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?

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 airways.

Other potential causes of cold are allergies, air pollutants, and air dryness.

To relieve sore throat, 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 on your throat — which may help you to deal with some symptoms of the illness.

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 a sore throat, 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 the 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 selling, transporting, and processing 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.
  • CBD isn’t included as part of an insurance plan 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 that 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 take 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
  • Dizziness
  • Tiredness
  • 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 a sore throat. 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.

CBD For Allergies: Can Hemp Oil Help Relieve Allergy Symptoms?

Allergies manifest as adverse reactions of an overactive immune system that do not occur in healthy people. Symptoms of allergies range from sniffling, sneezing to watery eyes, itchy throat, wheezing, and asthma attacks.

According to statistics, allergies are the sixth main cause of chronic illnesses in the United States, affecting roughly 19.9 million adults, as stated by the Centers for Disease Control and Prevention (CDC).

CBD is a plant-based compound unique to the Cannabis sativa L. family. Cannabis plants contain over 400 phytochemicals on top of CBD, so it goes without saying that at least one of these compounds can trigger allergies.

While the research into allergic reactions to products like CBD oil is scarce, the cannabis plant itself has been associated with allergies.

In today’s article, we’ll cover the topic of potential allergies to CBD oil; what may trigger them; what researchers are saying, and whether full-spectrum CBD oil can cause a person to experience typical allergy symptoms.

What You Need to Know About Allergies (Causes, Symptoms & Statistics)

Over 50% of the U.S. population suffers from allergies to at least one thing. Allergic rhinitis, also known as hay fever, is the most common type of allergy, affecting up to 30% of American adults and 40% of children.

There’s no cure for allergies, they can be effectively managed with the right diet, supplementation, and certain lifestyle changes. Of course, people with allergies should also avoid triggers.

Some allergies are milder than others, but there are people for whom this condition is a severe problem that requires an individual approach.

As mentioned, the symptoms of allergies include sneezing, itching, droopy eyes, a runny nose, and sometimes problems with breathing.

Allergies are triggered by a compromised immune system. The immune system controls allergic reactions; when it functions normally, it can distinguish from harmful and safe compounds to eliminate potential dangers. However, when the communication between its cells is disturbed, the immune system starts to identify normal substances as potential threats — releasing antibodies to attack them.

People with allergies produce antibodies every time they get exposed to the allergen.

The main antibody responsible for allergic reactions is histamine. The antihistamine medications are formulated to prevent antibodies from damaging the immune system. Popular antihistamine drugs include Claritin, which is available without a prescription.

Food allergies are more challenging to treat. The immune system attacks proteins in the food, causing serious symptoms such as anaphylaxis.

Anaphylaxis can be fatal if left without immediate aid. People with allergies usually carry special pens infused with epinephrine to stop an anaphylactic attack.

A 2009 study published in the journal Immunobiology found that cannabinoids such as CBD and THC could trigger immunosuppressive processes in an overactive immune system (1). According to the authors, these compounds may block the reactions of the immune system against the “hostile” molecules.

Does CBD Oil Help with Allergies?

Although the research into the health benefits of CBD oil for allergies is limited, multiple studies have highlighted its anti-inflammatory and immunosuppressant properties. Inflammation is the underlying cause of allergic reactions.

A 2011 research report published in the journal Free Radical Biology and Medicine analyzed the potential benefits of CBD for different inflammatory disorders (2). George W. Booz, the leading researcher and a professor in the department of pharmacology and toxicology at the University of Mississippi Medical Center, summarized them in the following way:

“Inflammation and oxidative stress are intimately involved in the genesis of many human diseases. Unraveling that relationship therapeutically has proven challenging, in part because inflammation and oxidative stress feed off each other. However, CBD would seem to be a promising starting point for further development given its antioxidant (although relatively modest) and anti-inflammatory actions on immune cells.”

The authors concluded there’s no clinical evidence to support the theory that CBD oil relieves allergic reactions, so while some studies suggest anti-inflammatory effects exist (and they’re potent), we need more long-term clinical trials to officially support the use of CBD for allergies.

Should You Vape CBD Oil for Allergies?

CBD vapes, such as vape pens, offer the highest bioavailability of all available products. Up to 56% of the vaporized CBD ends up in your system according to various studies. However, CBD vapes often contain other compounds aside from cannabidiol, including thinners such as propylene glycol or vegetable glycerin.

The problem with propylene glycol is that it breaks down into dangerous aldehydes when heated, which can further irritate the lungs. If your allergic reactions include coughing, wheezing, or asthma attacks, CBD vape oil can do more harm than good. Some studies have found that smoking cannabis improves the lung function and capacity of asthma sufferers, but they analyzed the efficacy of medical marijuana, which contains both THC and CBD in different ratios — not to mention that the researchers used cannabis flowers, not vape oil.

How to Use CBD Oil for Allergies

CBD oil is the product of choice for many first-time users. It contains a hemp extract suspended in a carrier oil to provide higher bioavailability. CBD oils are packed in 30-ml glass bottles with droppers attached to them for precise dosing.

People take CBD oil to prevent allergies as well as to fight their symptoms. That’s because this form of consumption offers a relatively fast onset of effects — around 15-30 minutes after ingestion — with a long duration time, up to 6 hours.

CBD oil is taken under the tongue. The user needs to squeeze out the desired amount of oil using the dropper, place a few drops under the tongue, and hold it there for up to 60 seconds. This route of administration allows the CBD to absorb into the bloodstream through hundreds of tiny blood vessels in the mouth. Since most of the ingested oil avoids the digestive system, it doesn’t lose potency as much as CBD capsules or edibles.

Speaking of which, oral CBD products are a great alternative for those who would like to have a premeasured dose of CBD with each serving, as well as for people living busy lifestyles. CBD capsules and edibles mask the earthy flavor of hemp extracts, which makes them more enjoyable. The effects of CBD also last longer — up to 10 hours — despite a delayed onset. When you take a CBD capsule or gummy, they need to be processed by the digestive system, so it may take up to 2 hours until you can experience the effects.

CBD oil is a better pick if you need to quickly ease your symptoms and gauge your dose more accurately. On the other hand, capsules and edibles are better to kickstart the day and bolster your immune system against the triggers.

Can You Be Allergic to CBD Oil?

An allergy to cannabis isn’t just a poor excuse for having red eyes during your adolescent times — it’s a real thing.

So, the answer is: yes, you can be allergic to CBD. Eating, touching, or inhaling cannabis plants can trigger allergic reactions as a result of contact with pollen. Inhaling that pollen may lead to hay fever.

A 2018 study found that people with allergies to plants, dust mites, cat dander, and mold, have a higher risk of developing an allergy to cannabis (3). However, no other study has yet investigated this subject as of this writing. More quality research is needed to establish a firm connection between cannabis and allergic reactions.

Considering the risk of allergies from pollen or mold, you should be particularly careful when choosing CBD products; purchase only from companies who use organically grown hemp and test their CBD oils in third-party laboratories for potency and potential contaminants. The latter may trigger an allergy to CBD oil that may not result from CBD per se.

Possible Allergic Reactions to CBD Oil

As mentioned earlier, an allergy to CBD can manifest in many different ways. Two people may experience completely different symptoms, so it can be difficult to tell the difference between a CBD allergy and the mild side effects of CBD.

Potential adverse reactions to CBD oil include dry mouth, changes in appetite, dizziness, fatigue, and diarrhea. These aren’t the symptoms of an allergic reaction to CBD. Fortunately, the majority of these effects are nearly nonexistent in regular doses.

Here are a few possible signs of a CBD allergy:

  • Skin irritations: when you use a CBD topical, you may notice hives or a rash as the symptoms of your allergy to CBD. However, these reactions may be caused by one of the many ingredients in creams and other skincare products, so make sure to scan the list of ingredients thoroughly.
  • Dry, itchy, or red eyes: this symptom is commonly associated with cannabis users — it results from inhaling THC — but some people might experience droopy, red eyes after taking CBD oil. If you have this kind of reaction, it might be a sign that you’re allergic to CBD.
  • Migraines: While a slight headache might occur after taking a higher dose of CBD, migraines are a severe reaction that can indicate an allergy to some of the ingredients in CBD oil.
  • Breathing difficulty: If you experience difficulty breathing, seek immediate help. This is most likely the side effect of poor-quality products that contain mold or hazardous additives.

People with plant allergies are advised to try CBD isolate instead of full-spectrum or broad-spectrum CBD. The latter is made using the entire plant, meaning they contain cannabinoids, terpenes, flavonoids, essential oils, and plant waxes. Such products carry a higher risk of triggering an allergic reaction.

You can try a few different CBD products — full-spectrum, broad-spectrum, and isolate — to find out which form of CBD works without any adverse reactions. We also encourage you to check with a doctor for medical advice on what to do when you start experiencing the symptoms.

Studies on Allergic Reactions to CBD Oil

  • A study conducted by the Duke University School of Medicine found that about 20% of the 100 people they tested had allergic reactions to linalool, while 8% were allergic to limonene. These are the two most commonly found terpenes in full-spectrum CBD oils (4).
  • Doctors from the University of California, San Diego, published a letter entitled “Marijuana and stoned fruit” in the Annals of Allergies and Asthma, where they reported a 24-year-old male marijuana daily user experienced an anaphylactic reaction after eating yogurt with hemp seeds (5).
  • In a 2013 study published in the Internal Archives of Allergy and Immunology, 21 patients with food allergies were tested in terms of reactivity to cannabis lipid transfer proteins (LTP), which are potential allergens (6). Twelve participants showed signs of allergies to cannabis, and all 12 had severe symptoms of food allergy than those without an allergy to the plant.

CBD & Allergies: Bottom Line

Although researchers have yet to fully understand the link between CBD and allergies, some studies have reported that the cannabinoid has remarkable anti-inflammatory effects. Inflammation lies at the roots of all allergies, so while CBD won’t cure them, preliminary research and anecdotal reports indicate that CBD oil may be able to help ease the symptoms.

That is, of course, if you aren’t allergic to cannabis. CBD itself may not be an allergen, but in combination with the remaining 400 phytochemicals from cannabis, it can trigger an allergic reaction, such as sneezing, sniffling, or red, droopy eyes. Allergies may also be caused by other ingredients in CBD oil, such as synthetic additives.

If you want to reduce the risk of experiencing an allergy to CBD, it’s best to purchase from a trustworthy company that sells high-quality lab-tested products. Always make sure to check for third-party lab reports — or Certificates of Analysis (COA) — to check if the product is free of contaminants, solvents, or plant residue. Spending some extra time on research will save you money on CBD oil.

As the number of CBD users grows, researchers will be able to collect more information about potential allergic reactions and how CBD oil can mitigate their impact on our health.

Do you take CBD for allergies? Or do you know someone who is allergic to CBD oil?
