Does CBD Thin Blood?: The Relationship Between CBD and Blood Thinners


There are a lot of different beliefs and a number of proofs to suggest that there is a level relationship between thin blood and CBD.


For many years, there have been rumors that CBD can cause thinner blood. Nonetheless, there isn’t any definitive scientific proof relating the two, although a lot of people have said that they have experienced this side effect after using CBD It is presumed that the thinning of the blood may be a likely basis for why some users notice that their skin takes on a paler color or observe a rise in bruising as well as other signs of bleeding. There has been speculation that the thinning of blood that consumers testify to undergoing is actually the CBD obstructing the clotting of blood.


In an article issued by Harvard Health, it was reported that blood thinners might actually not thin your blood; instead, they function as an anticoagulant, which aids in preventing the clotting of blood.



Anticoagulants, also referred to as blood thinners, are drugs that stop the body from producing blood clots. Blood flow to your heart, brain, and lungs could be obstructed by clots. Although the clotting of blood is a crucial biological process, having too much of it can result in issues that could be harmful.


Various blood thinners all function differently. To prevent cells from sticking to your blood arteries, several medications may thin the blood. Nevertheless, antiplatelets and anticoagulants make up the majority of blood thinners. Thus, these blood thinners function by delaying the formation of blood clots for a more extended period. Warfarin, Heparin, and Enoxaparin are three popular anticoagulant blood thinners.


So for people who experience issues of blood clotting and clogging, blood thinners can actually save their lives. But, these medicines can as well increase the chance of bleeding. This is of more concern, as you might expect when someone is going through a surgical procedure or operation. The likelihood of bleeding differs, of course, depending on the surgery you’re about to have done. However, the risk of increased bleeding seems to be incredibly low for a lot of small procedures.




According to Harvard Health Publishing, coumadin, a blood thinner, “may be increased to a greater extent” by CBD. Furthermore, it has the exact same principle as that of grapefruit juice for increasing the levels of other drugs in your blood. Additionally, some research suggests that Warfarin, the most used anticoagulant on the market, and CBD may interact with one another.


Different research making use of rats was done to investigate the anticoagulant properties of CBD. Blood coagulation tests suggest that CBD has minor anticoagulating effects, according to Dr. Alaa Abd-Elsayed. In other research, it was discovered that CBD oil suppresses the formation of platelets and anticoagulants, which may increase bleeding propensities.


So it seems that CBD has the ability to thin the blood. However, there is disagreement among medical specialists on the risks of using CBD prior to surgery. Some medical professionals think it’s better to stop using CBD up to 48 hours before your surgery. Some people assert that eating CBD shouldn’t cause any problems unless the patient is simultaneously taking blood thinners.


As it seems, CBD oil can function as a blood thinner. While in this process, CBD can reduce a person’s blood pressure. For this reason, an individual with blood-related issues may be exposing themselves to complications and risks by using CBD. So, if you have any blood pressure problems or you are presently using prescription drugs, it is recommended that you consult your doctor before consuming cannabis oil. It may be hard to know the best option as beliefs are still divided, and a general consensus is yet to be reached.



CBD is a chemical substance gotten from marijuana plants and is made up of; Cannabidiol is the non-intoxicating component of marijuana. Hemp ( a type of marijuana) that possesses lower than 0.3% THC (tetrahydrocannabinol) by weight, which makes it legal to purchase in all 50 states. So far, it is from industrial hemp and not from cannabis plants with larger amounts of THC. And chemicals that are known as cannabinoids function in the endocannabinoid system in our body just as neurotransmitters function, producing an anti-inflammatory reaction and blocking pain signals that have been sent to your brain.


Findings from some research indicate that CBD functions as an antithrombotic agent, which means it lowers the formation of blood clots. So, does CBD oil actually thin the blood?


It has been demonstrated that CBD has a slight blood-thinning impact. Yet, another study discovered that hemp oil which is seen in CBD alters platelets, which may lead to increased bleeding propensities.



According to a 2017 study, there may be a connection between cannabidiol and a blood thinning drug called Warfarin.

It is extremely crucial to keep an eye on the proper laboratory testing in patients who are using other blood thinners and cannabis products like CBD. If you take Warfarin at the same time as CBD, it can lead to Warfarin staying too long in the body, and this may present some adverse effects such as extreme bleeding or, worse off, an overdose. Patients who desire to make use of Warfarin with CBD should firstly talk with a doctor and see if it is safe for them to do so.



The real fact behind if CBD oils can be used as blood thinners remains unknown. Despite there being research to back it, there are still disputes in the medical society to ascertain if CBD oil can or cannot act as a blood thinner.


There are many variables at play when CBD oil and blood thinners are combined. Your general tolerance, general health, and your likelihood of experiencing potential drug-drug interactions can all have an impact. It would be best if you first talked to your doctor about including CBD oil in your pharmaceutical regimen because there are so many factors to consider. To guarantee that there is no systemic disturbance, you can devise a plan together.
