Does Cbd Oil Thin Your Blood? Side Effects You Should Know About.

Considering what CBD oil can do, it’s not surprising people are worried about CBD oil’s adverse reactions. In recent years, scientists and researchers have been studying cannabis compounds for their ability to help alleviate pain, improve sleep quality, and help with stress responses.

As new information about cannabinoids and CBD is discovered, concerns about its consequences continue to rise. Heart disease patients and others at risk may experience dire consequences when it interacts with certain medications.

What role does CBD oil play in blood thinning? Do anticoagulants such as warfarin interact with CBD oil? What should you do if you are going to have an operation? Here are all the answers you need to know about CBD oil and thinning agents.

Blood Thinning and CBD Oil

A combination of CBD oil and blood thinners can be dangerous, as both thin your blood, making your blood thinner than prescribed by your doctor. On its own, CBD oil would seem to have anticoagulant properties. According to a study, marijuana and its cannabinoids (THC and CBN) have anticoagulant properties on animal specimens. Other than those two extracts, CBD was not singled out.

Does CBD work in the same way as the two cannabis plant extracts discussed in that study? According to general consensus, yes. There is some evidence that CBD oil thins your blood. As Harvard Health Publishing points out, CBD can increase the concentration of blood thinning and other medications in the blood by competing with liver enzymes that break down these medications.

They do mention grapefruit’s similar effects. In the UK, the National Health Service (NHS) recommends taking warfarin if grapefruit juice is to be avoided. However, other blood-thinning medications are less risky when grapefruit juice is present in the body and competes with medications in the liver.

Negative Drug Interactions

Taking this logic backward, one might conclude that people who are concerned about negative drug interactions, bleeding problems, cardiovascular conditions, stroke histories, or other problems or at risk associated with CBD oil should not take it without consulting a physician.
Grapefruit Effect

In case you don’t know what the grapefruit effect is, eating grapefruit while taking blood thinners can impair the effectiveness of the medication. Grapefruit consumption affects several types of medications, including cholesterol-lowering agents, calcium channel-blocking agents, cytotoxic drugs, Entocort, and cyclosporin. Please note that this is not an exhaustive list, a number of others exist, so you should speak with your doctor about them.

You can get side effects from this drug because it increases the amount of medicine in your blood, altering its effects. These effects have also been observed with CBD oil, so if you use one of these drugs, CBD oil is probably not the best choice.

All things considered, it is of even greater importance that brands comply with their stated quantities. Currently, they are considered food supplements instead of medicines, which means there are fewer regulations, which means you should always check the results of third-party lab reports and only buy from reputable manufacturers.

Is CBD Oil Effective at Lowering Blood Pressure?

There are a lot of studies on this topic. According to a 2017 study, CBD lowers heart rate and blood pressure and acutely reduces resting blood pressure.

In other studies, CBD seems to have some positive effects during moments of stress on blood pressure. As of now, there is no evidence or research that supports CBD’s effectiveness in lowering blood pressure for long periods of time. There may be a misconception that thin blood results in lower blood pressure, but they are not related.

Blood pressure is created by the heart beating, but clotting prevents bleeding internally and externally. Platelets don’t affect blood pressure when added to the bloodstream. Despite platelets completely blocking the bloodstream in thrombosis, blood pressure remains unchanged.

This sudden drop in blood pressure, though, could have serious consequences for some people. In general, if you suffer from low blood pressure, you might have to stay away from CBD oil and hemp-derived products.

Reduce the Risk Factor

Make sure you seek medical advice from a trusted physician or medical professional prior to using CBD oil. The moment you decide CBD is a good option for you and you have no risk factors that could counter its advantages, it is crucial that you find a provider with products without harmful additives.

Whatever you choose, whether it’s edibles, CBD isolate, terpenes, extracts, topicals, hemp oil, or tinctures, look for a product that lists all its active ingredients. To give you an idea of what could happen, in 2018 the FDA warned products containing synthetic cannabinoids were contaminated by a substance referred to as brodifacoum – a poison commonly used in poisonous rodents.

According to the description of these being sold in convenience stores and gas stations, their suppliers were probably not reputable. Take the time to research what you are consuming prior to starting to take CBD oil. Supplements are not regulated by the FDA, which makes it crucial to do your research.
