Does CBD oil Thin Your Blood

by waqar

Cannabidiol, or CBD, is a natural compound derived from the hemp plant that has gained popularity for its potential health benefits. CBD oil is a common form of CBD that is easy to consume and has a wide range of uses. One question that has arisen around the use of CBD oil is whether or not it can thin the blood. In this blog post, we’ll examine the topic and explore what the current research says about CBD oil and blood thinning.

Does CBD Oil Thin Your Blood

To understand if CBD oil can thin blood, we first need to understand

what it means for blood to be thin. Blood thinning, also known as anticoagulation, is a process that reduces the body’s ability to form blood clots. This can be beneficial for people at risk for blood clots, but it can also increase the risk of bleeding. 

What is CBD Oil?

Cannabidiol (CBD) is a substance obtained from the cannabis plant that does not have psychoactive effects, meaning it does not cause the “high” typically linked to marijuana consumption. To create CBD oil, the CBD is extracted from the plant and then diluted with a carrier oil, including hemp seed oil or coconut oil.

What is Blood Thinning?

Anticoagulation, commonly referred to as blood thinning, is a mechanism that inhibits the formation of blood clots within blood vessels. Blood clots can be dangerous and even life-threatening, as they can block blood flow to vital organs, such as the heart or brain.

Research on CBD Oil and Blood Thinning

Research on CBD Oil and Blood Thinning

Although anecdotal accounts indicate that CBD oil may have blood-thinning properties, there is no scientific evidence to substantiate this assertion. Nonetheless, a limited number of studies have been conducted to investigate CBD’s potential impact on the cardiovascular system.

In a study published in the Journal of Clinical Investigation in 2013, researchers found that CBD positively affected blood pressure and reduced vascular inflammation in mice. While these findings are promising, they do not necessarily suggest that CBD oil can thin the blood.

Another study published in the Journal of Thrombosis and Haemostasis in 2019 investigated the effects of CBD on blood clotting in healthy volunteers. The study found that CBD did not affect blood clotting but did increase bleeding time. However, the study had a small sample size, and more research is needed to confirm these findings.

Overall, the research on CBD oil and blood thinning is limited and inconclusive. Before using CBD oil or any other supplement, consulting with a healthcare professional is crucial, particularly if you are on blood-thinning medications.

Will CBD Thin My Blood?(yes/no)

Cannabidiol (CBD) has not demonstrated a considerable impact on blood thinning. Nonetheless, it is essential to always seek advice from a healthcare expert before introducing any new supplement, particularly if you are using medication or have a medical issue related to blood clotting. Some studies have suggested that high doses of CBD may increase the risk of bleeding, so it is important to be cautious and seek professional advice before using CBD products.

Is it safe to use CBD oil alongside other blood thinners?

When combining CBD oil with blood thinners, there are several factors to consider, including your health, weight, and overall tolerance, which can impact potential drug interactions. Two of the remaining three FDA-approved oral anticoagulants used to treat irregular, rapid heart rates are metabolized by the CYP450 system, making them susceptible to CBD’s grapefruit effect. The oral anticoagulants in question are Rivaroxaban and Apixaban. However, a 2011 study showed that Dabigatran (Pradaxa), another oral anticoagulant, does not undergo CYP450 metabolism. While Dabigatran may have a few drug-food and drug-drug interactions, it is considered an alternative to warfarin treatment. It is advisable to speak with your physician before combining CBD with any blood-thinning medication to evaluate safety and potential interactions.

If you are on blood thinners and wish to use CBD, what are the safest ways to do so?

CBD can be used in several ways, including orally through oils, soft gels, isolates, and sublingual administration, inhalation via sprays, inhalers, liquids, and extracts, and topically through creams and lip balms. However, the effects of CBD can vary from person to person, making it essential to seek guidance from a doctor when using CBD alongside other medications.

A healthcare professional can help you establish the most secure method for incorporating CBD into your medication routine. They can assess what medications you are currently taking and how to balance them safely, potentially including blood tests before initiating treatment. By following your doctor’s guidance and recommendations, you can use CBD with confidence while minimizing the risk of potential drug interactions.

What are the dangers of using blood thinners?

Like all medications, blood thinners come with risks. Inhibiting blood clot formation can be particularly hazardous if bleeding takes place. If bleeding happens, blood thinners affect the blood’s clotting ability and platelet aggregation, leaving those taking these medications vulnerable to hemorrhagic shock.

Healthcare professionals typically inform patients about the associated risks when prescribing blood thinners. Patients are advised to adhere to the medication instructions carefully. Patients are also informed about complications when combining anticoagulant and antiplatelet medications with certain foods, vitamins, alcoholic drinks, or other medications.

It’s essential to give your healthcare provider complete details about your medications, diet, supplements, and lifestyle to assist them in evaluating the risk of using blood thinners. Frequent blood tests are necessary for individuals on blood thinners to assess the medication’s effectiveness and prevent excessive bleeding.

Patients on blood thinners require frequent blood tests to assess medication effectiveness and ensure the body is not predisposed to excessive bleeding. By working closely with your healthcare provider and staying vigilant, you can minimize the risks of using blood thinners.


Does CBD oil affect the blood?

CBD oil has not been shown to significantly affect blood pressure or blood clotting. It’s crucial to seek advice from a healthcare provider before starting any new supplements, particularly if you’re taking medication or have a medical condition that affects blood clotting.

What is the risk of CBD oil?

When used moderately, CBD oil is typically considered safe for most individuals. Nonetheless, some people may encounter side effects such as fatigue, diarrhea, or alterations in appetite or weight. CBD oil may also interact with specific medications. Hence it’s essential to seek advice from a healthcare professional before using it.

When should you avoid CBD?

CBD may not be suitable for everyone. It’s crucial to avoid CBD if you are pregnant or breastfeeding or if you have liver disease. Moreover, CBD may interact with specific medications. Hence it’s essential to seek advice from a healthcare professional before using it.

Does CBD calm the nervous system?

CBD has exhibited potential benefits for the nervous system, such as reducing anxiety and enhancing sleep quality. Nevertheless, more research is necessary to comprehensively understand how CBD impacts the nervous system.

What does CBD do to your veins?

More research needs to be done on CBD’s specific impacts on veins. Nonetheless, CBD has displayed potential advantages for the cardiovascular system by decreasing blood pressure and enhancing circulation. Furthermore, CBD’s anti-inflammatory properties could aid inflamed or damaged veins. However, further research is required to gain a comprehensive understanding of the effects of CBD on veins.


Determining whether CBD oil has blood-thinning properties is a complex issue, and the answer is currently unclear. While some studies suggest that CBD oil may possess anticoagulant properties, more research is required to comprehensively understand its potential effects in humans. If you’re contemplating using CBD oil for any health-related reasons, discussing it with a healthcare provider and evaluating the potential risks and benefits is crucial. With additional research, we can better understand the potential of CBD oil as a natural blood thinner and its role in promoting cardiovascular health.
