CBD oil has blood-thinning ability, and many people think that CBD’s blood-thinning property can benefit humans in many ways. Is CBD oil good for you? Bad for you? Something in between? What are the side effects of CBD oil? Although CBD oil is legal in most U.S. states and is widely accessible to purchase it’s important to understand the potential risks and dangers of CBD Oil.
Does CBD Oil Thin Your Blood?
CBD is the second most prevalent cannabinoid in the cannabis plant. CBD is touted as a magical ingredient, and almost every other product is CBD infused. For the past ten years, CBD oil is also making headlines for its potential health benefits such as treating heart diseases, regulating the sleep cycle and boosting mood, etc.
According to the world health organization, WHO; CBD is safe and well-tolerated in humans. Additionally, it does not show any abuse or dependence potential. But somehow, there is ongoing controversy about whether CBD can interact with anticoagulants and blood-thinning medications. Does CBD oil really thin your blood? Here is everything you need to know.
Does CBD Oil Thin Your Blood? What Does The Research Say?
CBD oil has many health and therapeutic uses, that’s why it is extremely popular nowadays. Many people use CBD oil to boost their energy, alleviate their mood, regulate their sleep, etc. CBD is extracted from hemp and mixed with carrier oils to make the required consistency of CBD oil. CBD oil is not intoxicating and doesn’t give the “head high” effects.
CBD oil has blood thinning ability, and many people think that CBD’s blood-thinning property can benefit humans in many ways.
Following Are Some Studies Regarding CBD and Its Effects On The Blood:
- According to a study published in the JCI Insight Journal, a single dose of CBD has an impact on the blood pressure of participants. Whenever you take CBD oil for any health reasons, it also dilates blood vessels. As a result, blood flows faster in blood vessels, and then there is less likelihood of blood clots.
- Anticoagulants are also known as blood thinners. These medicines help to prevent blood clotting in veins and arteries. Different blood thinners work in different ways. Some may thin the blood by preventing cells from adhering to your blood vessels. Blood thinners are a lifesaver for people who have issues such as blood clotting. Similarly, CBD has the ability to thin the blood.
- Another study showed that cannabinoids in broad-spectrum CBD oil could prevent thrombosis. Thrombosis is a condition in which blood clots are formed. Moreover, CBD extends the time of blood clot formation. This time is two times longer as compared to the subjects who don’t take CBD, and blood clots formed. This study also suggests that “cannabinoids, THC, and CBN, show anticoagulant activity and may be useful in future the treatment of diseases such as type 2 diabetes. Broad-spectrum CBD products don’t contain THC but all other cannabinoids and terpenes. So, more research is required to unveil the CBD’s effects on the blood thinning.
CBD Oil and Its Interaction with Other Medicines
CBD can interact with other medicines. So, if you are on any medication, then you must consult your doctor before starting CBD. According to some studies, CBD works better with Heparin, Dabigatran, and Edoxaban. These are clot inhibitors or blood thinners.
Want to know something interesting about grapefruit? If you are taking blood thinners, then grapefruit affects the way certain medicines work. Grapefruit can delay medicines’ absorption or excretion from the system.
According to an article published in Harvard Health , “CBD can increase the level of Coumadin in the blood. Coumadin is a blood thinner and its increased level results in blood thinning. Additionally, CBD can “raise the levels of other medications in your blood by affecting the liver enzymes. Furthermore, some studies indicate that there is an interaction between CBD and Warfarin. Warfarin is the most common anticoagulant available in the market.
Frequently Asked Questions
Q. Should I Stop Taking CBD Softgels A Few Days Before My Surgery?
This is something to consult with your doctor or surgeon. Everybody is different, and their body system reacts differently to CBD oil. Similarly, different surgical procedures have the various risks of bleeding. To stay on the safer side and as a precautionary measure, stop taking CBD a few weeks prior to your surgery. Moreover, your doctor can give you better advice in this matter as he knows your history and health issues.
Q. Should I Stop Taking CBD Before Going for A Tattoo?
When you decide to get a tattoo, you stop taking pain killers, blood-thinning medicines, and alcohol a few days prior to tattooing. It is ideal to stop taking CBD oil or any other form of CBD. Thinning of blood makes it hard for artists to draw tattoos, and there are chances of over bleeding. Many people take CBD oil to calm their nerves and for better sleep, so it is hard for them to stop using CBD oil. For more clear guidance, you take advice from your health care practitioner, or sometimes an experienced tattoo artist can guide you well.
Q. Is Topical Use of CBD Also Linked with Blood Thinning?
There is no clear and scientific evidence regarding this matter. Many people massage CBD oil or CBD oil-infused creams on different body parts to reduce pain and inflammation. There is not any scientific research available to prove that topical CBD oil can cause blood thinning.
Wrapping Up The Things
CBD and its blood-thinning ability require more research and human clinical trials. Many other factors such as weight, health issues, and tolerance level can affect CBD’s ability and its interaction with blood thinners. If you are taking blood thinners and want to take CBD oil, then you must consult your doctor. Your doctor and health care practitioners can adjust your dose, and you can safely add CBD to your medicine regime.
CBD’s blood-thinning property is not a bad thing at all; it opens new doors for future research. It also calls for new opportunities to discover new ways to tackle some biggest health issues, such as brain strokes and heart diseases. As you know, blood clots are the common reason for heart attacks and hemorrhage. So, there is a need for more human experiments and clinical trials to unveil the true potential of CBD oil and its effects.
What Are the Side Effects of CBD Oil?
Is CBD oil good for you? Bad for you? Something in between? What are the side effects of CBD oil?
Cannabidiol, or CBD oil, is an extract from the cannabis plant. It has boomed in the wake of the legalized marijuana movement, now that businesses can grow and sell the substance freely in several states.
Advocates market CBD oil typically as a health supplement, and they do so comprehensively. It has started showing up everywhere from web banners to smoothie shops. While it has few recreational properties, CBD oil’s boom in recent years is through the quasi-medical field. Like turmeric, ginseng and tinctures, CBD oil promises to ease a wide variety of ailments without the invasiveness of pharmaceutical drugs.
The question is… what is it really doing to you?
Does CBD Oil Work?
Cannabidiol is one of the two active ingredients in marijuana, but on its own is not enough to get you high. It can, though, help you feel better under the right circumstances.
While doctors and researchers take CBD oil’s role in medicine seriously, much of its profile has been raised by salesmen who make extravagant promises that no medicine (no less supplement) could hope to fulfill.
Some CBD oil salesmen promise that their product can cure everything from anxiety to cancer. They cram it into every product that can soak up a liquid, including gummies, shampoo, toothpastes and even pills for your cat. In the low-water mark for any “medical” supplement, you can now buy it at many juice bars and coffee shops as an additive that can somehow take your banana-strawberry smoothie to 11.
All of which is a shame, because this associates CBD oil with the bottomless deceit that is the world of medical supplements. Yet the substance has some early promise. As noted on Harvard Medical School’s website, CBD oil has some evidence linking it to treatment for epilepsy, seizures, chronic pain and arthritis.
There isn’t enough evidence to say that the oil definitely does help with these things, nor that simply cramming some in a milkshake will do the slightest bit of good, just that doctors are optimistic about their research. For more information on the medicine of CBD oil, see our article here.
What Are the Side Effects?
That’s how CBD oil might help. But can it hurt? Usually, no. It is generally not habit-forming, and most side effects are minor.
According to a report by the World Health Organization, “CBD appears to have little effect on conditioned place preference or intracranial self-stimulation… [It] exhibits no effects indicative of any abuse or dependence potential.”
“To date, there is no evidence of public health related problems associated with the use of pure CBD.”
In other words, there is no evidence at the moment that CBD oil tends to be either physically or psychologically habit forming.
Dangerous Side Effects of CBD Oil
There are some known real risks to CBD oil, however. Be absolutely certain to consult a doctor before using CBD oil if any of the below apply to you.
• It can lower your blood pressure and interact with medication.
Mostly, CBD oil is benign. Its side effects might leave you feeling unwell for a little while, but they will pass. But this is a medication, even if it is marketed carelessly, and that means it can have a powerful effect on your body.

CBD oil can act as a blood thinner and in doing so it can lower your blood pressure. For someone who has issues with blood pressure this can pose very real risks.
It can also interact with medications through “the exact same mechanism that grapefruit juice does,” according to an article on the Harvard health blog. While rarely a significant concern, on certain medications these interactions can be harmful or even deadly, according to the FDA. If you have blood pressure issues, are taking prescription drugs or have ever been warned about ingesting fruit juice, citrus or fermented products, consult your doctor before touching CBD oil.
• It can make Parkinson’s disease worse.
Some research indicates that CBD oil can exacerbate the symptoms of Parkinson’s Disease. This research is ongoing, but patients should avoid the product until more definitive results come out.
Mild Side Effects of CBD Oil
Most of the side effects of CBD oil are moderate. Unless you fall into one of the specific categories above, the odds are that this is a generally benign product with limited negative consequences, according to one research paper. Most of those include:
It can cause nausea and general sickness.
Nausea and gastrointestinal issues are a pretty common side effect of CBD oil. This can lead to vomiting, diarrhea, dizziness and other symptoms associated with a digestive problem (think how you would feel after eating something that disagreed with you). In part, some people simply don’t digest CBD oil well. This is not uncommon with oils and supplements.
However, this is also often caused by the fact that this is an unregulated supplement. There are no standards for dosage and safe measurement, so it’s quite possible that you could get an amount far in excess of what your body can handle. At this point, your body will simply flush it out. Unpleasantly.
• It can cause drowsiness and light-headedness.
This side effect should come as no surprise. Doctors have long looked at cannabis as a treatment for sleep disorders, and CBD oil is no exception. Putting you to sleep is a feature, not a bug. Just don’t be surprised if your CBD latte doesn’t pack the caffeine punch you expected.
• It can cause loss of appetite and dry mouth.
Ironically, perhaps, for a cannabis product, CBD oil has been linked to loss of appetite in some people. Along with dry mouth, it can simply leave you feeling unpleasant after ingesting. As with most other side effects, this will pass in time.
Is CBD Oil Legal?
Like all things marijuana, the legal status of CBD oil is ambiguous and highly state-dependent. While many states have legalized it for production and sale, this still violates federal law. The Department of Justice has currently decided not to prosecute individuals for possession and sale of marijuana products in states where this is legal, but that’s a discretionary act.
Once again this gets complicated. When extracted from cannabis, CBD oil counts as a marijuana product. However, in some cases growers can produce CBD oil from hemp. The 2018 Agriculture Improvement Act made this form of CBD oil production legal under federal law.
Cannabis-extract CBD oil is typically legal in states that have also legalized recreational marijuana, however its status is usually complicated.
CBD oil in all forms is regulated as a medical supplement, because this is typically how it is advertised. As a result, only five states currently have no significant restrictions on its sale and consumption. Every other state has either restricted it through marijuana laws or limits the sale of CBD oil in some form, whether through food and drink regulation, medical regulation or other forms of restriction.
In short, there’s a different answer for this question for every single state. Make sure to research the laws of your state carefully, and for more information check out our article here.
The Bottom Line
Like most supplements, CBD oil rarely does what it promises. It does have some early medical potential, and doctors may prescribe it for patients at risk of seizure or with inflammatory issues. However, as an over-the-counter oil or when infused into a snack cake it probably won’t do you much good. You may see some benefits in connection with CBD oil’s anti-anxiety or sleep aid properties, but the odds are that any real improvements are largely psychosomatic.
Still, if it works for you there’s probably no harm in it either. Unless you fall into one of the specific categories listed above, CBD oil’s side effects are generally mild and of limited duration. Like with all medical changes, alert your doctor if you begin taking it regularly, but otherwise it will probably do neither harm nor good.
Understanding the Risks of CBD Oil
CBD is short for cannabidiol, a chemical which is extracted from the hemp plant and then diluted with a carrier oil like coconut or hemp seed oil. While both CBD and marijuana are derived from the cannabis plant, CBD does not contain enough tetrahydrocannabinol (THC) to produce mind-altering effects. Hemp contains 0.3% or less THC, while marijuana contains higher than 0.3% THC.
CBD interacts with the body’s endocannabinoid system (ECS), which helps regulate the immune system, appetite, sleep, mood, digestion, inflammation, pain, motor control, temperature regulation, reproduction, and memory.
The FDA and CBD oil
Although CBD oil is legal in most states within the U.S. and can be purchased at your local drug/health food stores, smoke shops, and gas stations, only one CBD product has been reviewed by the Food and Drug Administration (FDA) for safety. That drug, Epidiolex, is a purified form of CBD that was approved by the FDA in 2018 for the treatment of certain seizure disorders. During their review of Epidiolex, the FDA did identify an increased risk of liver injury from the product but determined the risk could be managed provided the drug was taken under medical supervision.
Other than Epidiolex, the FDA warns that no CBD products have undergone a strict evaluation process to determine if they are “safe and effective to treat a particular disease, what the proper dosage is, how they could interact with other drugs or foods, or whether they have dangerous side effects or other safety concerns.”
The FDA also warns that testing of some CBD products has revealed the presence of contaminants like pesticides and heavy metals, and that some did not contain the levels of CBD claimed.
It is illegal for companies to promote their CBD products as a cure, treatment, or prevention of any specific disease or condition. Companies that make such claims are sent a warning letter from the FDA.
Why do people use CBD oil?
Although there have yet to be any large-scale human studies on CBD, there is scientific evidence that the oil may relieve pain, reduce anxiety and depression, reduce side-effects of cancer treatment, reduce epileptic seizures, and lower blood pressure, as well as deliver anti-inflammatory and other beneficial effects.
The Mayo Clinic reports that while CBD is usually well-tolerated, it can cause such side effects as dry mouth, diarrhea, reduced appetite, drowsiness and fatigue. Some users have also reported experiencing nausea and irritability.
Potential risks with CBD oil
Harvard Health Publishing says two of the biggest concerns with CBD use are:
- CBD can increase the levels of other medications in the body the same way grapefruit juice does.
- CBD is sold as a supplement and not required to undergo the same stringent testing as FDA-approved medications.
Agreeing with the FDA, Harvard warns the lack of regulation means consumers can’t be certain what is contained in the product and whether the dose is accurately stated.
While some CBD providers submit their products for independent lab testing, other providers do not and have no verifiable way of proving what is contained within their oil. Since the industry is largely unregulated currently, consumers often have little insight into what the products contain unless they are able to access the results.
And because a large segment of the U.S. population takes one or more prescribed and/or over the counter medications while also taking CBD oil, many are at increased risk of a dangerous interaction. A study published in JAMA Internal Medicine found that due to concurrent use of prescription medications and dietary supplements in 2011, “15% of older adults [are] potentially at risk for a major drug-drug interaction.” This estimated risk had increased from 8.4% in 2005.
Drug interactions not only impact the efficacy of a medication, but they can also cause harmful side effects. Many drugs and toxins are broken down in the body by a vital enzyme called CYP3A4, mostly found in the liver, allowing them to be eliminated by the body. Grapefruit has been found to interfere with the metabolization process, allowing the drug to build up in the body, which can be dangerous.
CBD appears to have a similar effect, which is quite concerning, as approximately 60% of medications on the market interact with CYP3A4 enzymes. Check the FDA website for information about which drugs don’t interact well with grapefruit. And always consult your healthcare provider, prior to using CBD, for medical advice specific to your needs.
Risks of CBD when used with other medications
Research indicates that CBD can interact with medications including:
- Blood Thinners: A study published in the journal Epilepsy and Behavior Case Reportsfound a “clinically significant interaction between pharmaceutical grade cannabidiol (Epidiolex®) and warfarin, one of the most widely used oral anticoagulants.” If CBD disrupts the metabolization of a blood thinner like warfarin, the build-up of drug levels in the body could result in dangerous bleeding. It’s important that patients prescribed Epidiolex are carefully monitored by health professionals.
- Epilepsy Drugs: Even though the FDA approved the CBD drug Epidiolex to treat certain forms of epileptic seizures, incorrect doses can result in more aggressive seizures. This drug should only be used under close medical supervision.
- Chemotherapy Drugs: As with most drugs, chemo drugs are manufactured considering the likely rate of metabolization. If CBD slows down that rate, concentrations of the drug can build up in the body which could result in toxicity.
Other research has also linked CBD to interactions with:
- Antidepressants and Anti-anxiety Medications
- Cold or Flu Medications
- Blood Pressure Medications (Beta Blockers)
Always consult a doctor if you’re taking any of the medications above to understand their interaction risks.
The FDA continues to advise the public to be cautious about using CBD until more scientific research supports its efficacy and safety.
