cbd oil and afib

There is ongoing research into the use of purer forms of CBD for a variety of conditions, including heart and circulatory diseases and, in particular, diseases of the heart muscle, including myocarditis and some types of cardiomyopathy.

Many of these can be easily picked up from reputable high street stores, such as Holland & Barrett or Boots.

Prices can be high: a 500mg bottle of CBD oil oral drops could set you back as much as £45. Not that this has put people off: over the past two years, sales of CBD have almost doubled in the UK, putting regular users at an estimated quarter of a million.

Can CBD help the heart?

CBD, or cannabidiol, is a chemical that’s extracted from the leaves and flowers of the cannabis plant. Cannabis itself is an illegal class B drug, as is the compound THC (tetrahydrocannabinol) which it contains. But pure CBD isn’t illegal, as it doesn’t cause the intoxicating effects of cannabis.

The biggest difference between CBD used in clinical trials and in stores is the dose. Research has shown that some products contain very little CBD (or even none at all). Others contain THC or other illegal drugs, or even alcohol instead of CBD. By contrast, in clinical trials the CBD is purified, manufactured to a very high standard and given at a much higher dose. It is also taken regularly and under medical supervision.

“In terms of the products found in shops, there’s virtually no evidence to support the claims made for a lot of them.” Harry Sumnall, Professor in Substance Use at Liverpool John Moores University

“It’s clear that CBD has potential,” says Professor Sumnall, “but we’re at a very early stage of that research.”

When you use CBD oil, your liver breaks it down. During this process, it could interfere with your medications for heart failure or other heart conditions. “CBD has known interactions with warfarin, certain statins, calcium channel blockers, beta-blockers, and nitrates. Just because a supplement is ‘natural’ doesn’t mean that it is safe,” Lundgren says.

“CBD oil may not have the same properties, and it can actually cause gastrointestinal distress like diarrhea or cause decreased appetite. CBD products can include unknown ingredients and may not be accurately labeled,” he says.

Could CBD oil ease your heart failure symptoms or help you manage your condition? This herbal supplement is sold over the counter and may be marketed with various health claims, but heart experts aren’t so sure it’s worthwhile or even safe if you have heart failure.

What We Know About CBD

But there isn’t really any evidence to prove that it will relieve heart failure symptoms or be safe to use if you have heart failure, he adds.

CBD oil must be studied in randomized clinical trials on people, not animals, before it can be considered safe or effective for heart failure, Lundgren says. Until that happens, he advises against buying or using CBD. “There is some evidence that CBD can cause liver injury as well as lead to male infertility issues. When consumed with alcohol, individuals may experience increased drowsiness, which can lead to household injuries.”

JCI Insight: “A single dose of cannabidiol reduces blood pressure in healthy volunteers in a randomized crossover study.”

“The reasons consumers take CBD had not been previously studied because experts lacked access data where large groups of users discussed in detail why they take CBD,” said Dr. Eric Leas, Co-Founder of the Center for Data Driven Health, Assistant Professor in the Herbert Wertheim School of Public Health and Longevity Science at UC San Diego, and lead author.

While many think that using CBD poses few risks to consumers trying CBD out, the team notes that taking CBD can harm patients in other ways that warrant cautious use. “There are several documented cases of CBD products leading to mass poisons, because unlike FDA-approved medications there are no uniform safety standards governing the manufacture or distribution of CBD,” said Mr. Erik Hendrickson, study co-author and research associate with the Center for Data Driven Health. “CBD can also interact with patients’ prescribed medications, including resulting in rare but dangerous side effects such as liver damage and male reproductive toxicity,” added Dr. Smith who is also a practicing physician.

Mining Public Testimonials to Understand Why Patients Use CBD

“The obvious harm is that some patients might forgo seeing a physician or taking medications with known, tested and approved therapeutic benefits in favor of CBD and thereby become sicker or succumb to their illness,” added Mr. Rory Todd, study co-author and research associate in the Center for Data Driven Health.

A random sample of posts was drawn and analyzed by the team who labeled them according to if the poster testified to using CBD to treat a diagnosable medical condition or using CBD for non-specific wellness benefits. “On r/CBD users tell us in their own words why they take CBD,” added Dr. John W. Ayers, also with the Center for Data Driven Health and Vice Chief of Innovation in the Division of Infectious Disease and Global Public Health who co-authored the study. ”

A new study lead by the Qualcomm Institute’s Center for Data Driven Health at the University of California San Diego, published in JAMA Network Open, reviewed CBD user testimonials to discover why they take CBD, finding the vast majority used CBD to treat diagnosable medical conditions, including for psychiatric, orthopedic, and sleep conditions while fewer took CBD for wellness.
