CBD’s popularity has been given a boost by the fact that two CBD-containing medicines have been approved for prescription use by the NHS in England: Epidyolex, which has been found to reduce the number of seizures in children with severe epilepsy, and Sativex, which contains a mixture of CBD and THC, and is licensed for treatment of muscle stiffness and spasms in people with MS.
“It’s clear that CBD has potential,” says Professor Sumnall, “but we’re at a very early stage of that research.”
What is CBD used for?
Many of these can be easily picked up from reputable high street stores, such as Holland & Barrett or Boots.
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.
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 a follow-up study, where the researchers gave 26 men 600 mg of CBD or a placebo for seven days, the results were mixed. Measurements of resting blood pressure revealed that the participants had developed a tolerance to the CBD over time, but CBD ’s ability to lower blood pressure during stress persisted. (Of course, if you are already dealing with low blood pressure, the blood pressure–reducing effects of CBD are something to be aware of, and you may need to avoid high doses.)

Inside Your Arteries
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.
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.
CBD may protect against cardiac arrhythmias or irregular heartbeat.
