With heart failure, the heart cannot supply the body’s cells with enough blood, leading to symptoms that can have a tremendous impact on your quality of life.
Cannabidiol oil is extracted from the leaves and flowers of the cannabis plant. CBD is a chemical that’s unique to the cannabis plant. The two major cannabinoids contained in cannabis plants are:
Read on to learn more about CBD’s benefits for the heart, what CBD oil is, side effects, and forms of CBD oil.
Overview of Heart Failure
CBD cannot cure heart disease or congestive heart failure, but it is being studied for ways it may help reduce symptoms or prevent heart disease. However, CBD has not been shown in large studies to prevent diseases that lead to heart failure.
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.
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.
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.
Does CBD work?
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.”
Inflammation is part of the process that leads to many diseases, including coronary heart disease, high blood pressure and stroke, and there is some evidence that CBD has anti-inflammatory properties. Other studies have suggested that CBD can have a protective effect on the heart: this has been proven in rats after a heart attack and in mice with some of the heart damage associated with diabetes. But because these studies are often based on findings in a lab or in animals, not in humans, we cannot yet be confident that CBD will benefit the human heart.
Can CBD help the heart?
Many of these can be easily picked up from reputable high street stores, such as Holland & Barrett or Boots.
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.

The issue of drug interactions is a significant one. CBD inhibits two powerful pathways the body uses to detoxify drugs, the CPY3A4 and CYP2D6 systems. This is a serious issue for you. Ticagrelor (Brilinta), an anticoagulant, is metabolized by CYP3A4, as are some of the statin drugs usually prescribed to people with heart blockages.
There is also an issue with proving the dosage and purity of products said to contain CBD.
