Research shows that CBD can help maintain healthy cardiovascular function and prevent heart disease on a number of fronts, including protecting against hardening of the arteries, lowering blood pressure, and reducing the incidence of potentially dangerous arrhythmias.
Heart disease is a catchall phrase for the disease that develops when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart, leading to events like heart attack. It’s the leading cause of death in the United States, killing about 655,000 Americans each year, which is about one in every four deaths. Key risk factors for heart disease include unhealthy diet, physical inactivity, diabetes, overweight and obesity, and excessive alcohol use.
Inside Your Arteries

CBD also delays the reabsorption of a chemical called adenosine (meaning that you have more of it in circulation), which quells inflammation and helps maintain healthy heart function.
Since cannabinoids also mop up free radicals — and improve the effects of other antioxidants in the body — CBD may also protect against heart disease by reducing the cellular damage that happens when we’re exposed to free-radical producers like processed foods and environmental pollution.
“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
But so far, Professor Sumnall points out, CBD products in shops are marketed as food supplements, not medicines, so none of them have gone through this process.
The choice of CBD products has exploded recently: you can buy oils, capsules, muscle gels, sprays and oral drops, as well as beer, tea, sweets, hummus and even CBD-infused clothing.
What is CBD used for?
A 2018 report by the World Health Organization suggested that CBD may help treat symptoms relating to conditions such as cancer, Parkinson’s disease, multiple sclerosis (MS), anxiety, depression, insomnia and Alzheimer’s disease.
CBD is the latest health craze to sweep the high street, with claims it can help everything from chronic pain and inflammation to anxiety. But what is CBD, and can it really help the heart? Emily Ray finds out.
Harry Sumnall, Professor in Substance Use at Liverpool John Moores University, says: “In terms of the products found in shops, there’s virtually no evidence to support the claims made for a lot of them. There’s a lot of marketing that says CBD is a ‘miracle of the modern age’; however, the marketing has actually overtaken the evidence of what it’s effective for.”
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.
He watches his vitamin K intake regularly. He has read conflicting stories about how tea interacts with warfarin by making INR levels high.
CBD is typically sold as an oil, and has been receiving press as a potential treatment for a wide variety of medical issues. Many or most of these claims have no data to support them. Anecdotal reports, such as most blogs, are neither reliable nor scientific (and may or may not be true).
I can’t recommend CBD products given the medications you are taking, but would suggest you consider alternative treatments.
