Does CBD Oil Help with Colds? A Deep Dive into the Research

As winter approaches, so does the inevitable cold and flu season. One remedy that has been gaining traction is CBD oil, a compound derived from the cannabis plant. Known for its potential therapeutic benefits, CBD oil is often touted as a natural alternative to over-the-counter cold remedies. But does CBD oil really help with colds?

This blog post aims to delve into the research surrounding CBD oil and its potential effects on the common cold. We’ll explore the science behind CBD oil, review existing studies, and discuss its potential pros and cons as a treatment for cold symptoms.

Understanding Colds

Firstly, let’s define what a cold actually is. A cold is a viral infection of the upper respiratory tract, caused by one of many viruses that can spread easily from person to person. The most common symptoms include a runny nose, sore throat, coughing, and mild body aches. While there is no cure for the common cold, symptoms typically improve within a week to ten days.

Understanding a cold is fundamental to evaluating potential remedies like CBD oil. At the core, a common cold is a viral infection that primarily affects the upper respiratory tract. It is typically caused by a variety of viruses, with rhinoviruses being the most common.

The disease is highly contagious and can easily spread from person to person through droplets in the air or by touching contaminated surfaces. Common symptoms include a runny or stuffy nose, sneezing, a mild headache, sore throat, and a general feeling of malaise.

These symptoms usually appear one to three days after exposure to a cold-causing virus and resolve within seven to ten days. However, some colds can last up to two weeks, particularly in children, the elderly, and those with weakened immune systems.

What is CBD Oil?

Before we dive into the research, it’s important to have a basic understanding of CBD oil. CBD (short for cannabidiol) is a compound found in the cannabis plant. Unlike its cousin THC, CBD does not produce psychoactive effects and has been legalized for medicinal use in many states. CBD oil is typically extracted from hemp, a variety of cannabis that contains low levels of THC.

CBD oil, or cannabidiol oil, is a therapeutic compound that has been gaining recognition in the health and wellness world. CBD is derived from the cannabis plant, specifically the hemp variety which is known for its low THC or tetrahydrocannabinol content. Unlike THC, CBD does not have psychoactive properties, meaning it does not result in the typical ‘high’ associated with cannabis use.

The process of deriving CBD oil involves extraction from hemp plants, followed by dilution with a carrier oil like coconut or hemp seed oil. Common uses of CBD oil typically revolve around its potential therapeutic benefits. It is often used for pain relief, reducing anxiety and depression, alleviating cancer-related symptoms, and even exhibiting neuroprotective properties.

However, it’s important to note that while many users claim benefits, more research is needed to fully understand its effects and potential side effects.

Research on CBD Oil and Colds

So far, there have been limited studies specifically examining the effects of CBD oil on colds. However, there is evidence to suggest that CBD may have potential benefits for the immune system. A study published in the Journal of Immunology found that CBD has immunosuppressive and anti-inflammatory properties, which may help reduce cold symptoms.

Additionally, a review of studies published in the British Journal of Clinical Pharmacology concluded that CBD may have therapeutic potential for various inflammatory conditions. These findings suggest that CBD oil may have the potential to alleviate some common symptoms associated with a cold, such as inflammation and pain.

The body of research around CBD oil’s effects on colds, while still growing, offers some interesting potential implications. Preliminary studies suggest that CBD oil may interact with the immune system in a way that could potentially alleviate certain symptoms of the common cold.

For instance, a study published in the Journal of Immunology highlighted CBD’s immunosuppressive and anti-inflammatory properties, which could play a role in symptom management. This might be particularly relevant for cold symptoms such as a sore throat or congested sinuses, both of which involve an inflammatory response.

Additionally, a review of studies in the British Journal of Clinical Pharmacology pointed to CBD’s potential therapeutic value in treating various inflammatory conditions. CBD’s pain-relieving properties, often recognized in the context of chronic pain management, might also be beneficial in addressing the discomfort often associated with colds.

While these findings are promising, more comprehensive and specific studies are needed to conclusively determine the potential benefits and limitations of using CBD oil as part of cold treatment regimens.

Pros and Cons of Using CBD Oil for Colds

While the potential benefits of CBD oil for colds may seem promising, it’s important to consider both sides before incorporating it into your treatment plan. Some advantages of using CBD oil include its natural origin, lack of psychoactive effects, and potential anti-inflammatory properties.

However, there are also potential drawbacks and side effects, such as dry mouth, low blood pressure, and interactions with certain medications. It’s always best to consult with a healthcare professional before trying any new treatment.

When considering the advantages and disadvantages of using CBD oil for managing colds, it’s crucial to weigh both sides. On one hand, CBD oil offers several potential benefits. It’s a natural product derived from hemp, and it lacks the psychoactive properties that are often associated with cannabis. This means it won’t alter your state of consciousness or result in a ‘high.’

Moreover, its potential anti-inflammatory properties, as suggested by research published in the Journal of Immunology, may have a role to play in managing symptoms like a sore throat or congested sinuses, which are inflammatory responses. Despite these potential benefits, there are also drawbacks to be mindful of.

Side effects can include dry mouth, low blood pressure, and, in some cases, an interaction with other medications. These side effects underscore the importance of consulting with a healthcare professional before introducing CBD oil into your treatment regimen. It’s important to remember that while the research on CBD oil and colds is growing, it is still in the early stages.

Therefore, expert opinions and recommendations consistently emphasize the need for further studies and individual medical consultation.

How to Use CBD Oil for Colds

When considering how to use CBD oil for colds, there are several methods of consumption to choose from. Ingestion involves swallowing CBD oil directly or mixing it with food or drink.

This method allows for the CBD to be absorbed gradually as it’s metabolized by the body, which may result in a more prolonged effect.

Inhalation, either through vaping or using a spray, offers a faster onset of effects as the CBD is absorbed directly through the lungs into the bloodstream.

Finally, topical application of CBD oil could be beneficial for localized symptoms such as a sore throat or congested sinuses.

Regardless of the method chosen, it’s important to start with a low dose and gradually increase as necessary. A typical starting dosage might be 5-10mg two or three times a day, although this can vary depending on factors like body weight and the severity of symptoms.

Always take note of any potential interactions CBD may have with other medications or supplements you are taking, as it can affect their absorption or efficacy. Due to the complex nature of these interactions and individual body responses, it’s recommended to consult with a healthcare professional to establish the most suitable dosage and administration method for your needs.


In conclusion, the research on CBD oil and its potential effects on colds is still in its early stages. While there is evidence to suggest that CBD may have therapeutic benefits for the immune system, more studies are needed to fully understand its effects on cold symptoms. As always, it’s important to consult with a healthcare professional before incorporating CBD oil into your treatment plan.

The potential of CBD oil as a remedy for common cold symptoms is a fascinating area of study. Current research points towards CBD’s immunosuppressive and anti-inflammatory properties which could help manage symptoms such as sore throats and congested sinuses.

However, as with any treatment, there are potential drawbacks including side effects and interactions with other medications. While preliminary studies offer promise, it’s essential to discern that these findings are in their nascent stages and more comprehensive research is warranted.

Despite the enthusiasm around CBD oil’s potential benefits for colds, it should not replace professional medical advice. Future research should aim to delve deeper into understanding the efficacy of CBD oil for colds, provide more substantial scientific evidence, and explore ways of minimizing potential side effects.

Until then, the use of CBD oil for colds should be approached with caution and under the guidance of a healthcare professional.
