The prevalence of heart disease is on the rise, and it is the leading cause of death in both men and women.

Various causes, such as narrowed blood vessels or abnormal valves, can be involved in cardiac disorders. While it can affect anyone, an unhealthy diet, smoking, sedentary lifestyle, and diabetes may increase the risk of cardiac diseases.

Managing health conditions is complicated, especially cardiovascular disorders. A myriad of treatment options are available, and the best suitable for you depends on the type of heart condition you have.

However, as prescription drugs come with an array of side-effects, more and more people are opting for alternative treatment options.

Cannabidiol or CBD has been getting a lot of buzz in this area.

So, what is CBD, and can it be used for heart disorders? Besides, does it interact with medications used to manage heart disorders?

Let's understand CBD?

CBD is an important cannabinoid present in the cannabis plant. On hearing cannabis, the first thing that may worry you is the “high” feeling.

However, unlike tetrahydrocannabinol (THC), cannabidiol is non-psychoactive and thus won’t make you high.

So, how does it work in your body?

Well, it affects your endocannabinoid system— a system that helps to maintain homeostasis or a state of an even state. If your body goes out of the normal state due to any disease or inflammation, CBD boosts your endocannabinoid system to get it back to normal.

While anecdotal evidence shows the health benefits of CBD, there is a lot to be found more.

Given these caveats, should you try CBD for heart diseases?

Let’s see what research says.

Is it Effective for Cardiac Disorders?

CBD’s antioxidant and anti-inflammatory properties can help to reduce the risk factors of cardiac diseases, such as high blood pressure. CBD may also lower the risk of complications, such as stroke.

What Research Has to Say


High blood pressure or hypertension is a common risk factor for cardiovascular disorders. Stress may cause a spike in your blood pressure, and CBD is seen to lower the peak. Studies have shown that:

  • CBD can lower both heart rate and blood pressure
  • CBD lowers pressure when compared to the placebo group

However, one study also shows that CBD may not help during non-stressful conditions


As we talked before, cardiac disorders increase the risk of stroke. An ischemic stroke, a type of stroke where a blood clot blocks blood flow to the brain, is commonly associated with heart diseases. It may also cause a blood vessel to break in your brain, resulting in hemorrhagic stroke.

According to research:

  • CBD prevents further brain damage in stroke patients by enhancing their brain functions.
  • Cannabidiol could also improve blood flow to the brain during a stroke.

Safety and Interactions

CBD is relatively safe, and researchers believe that there are rare possible adverse effects. According to the World Health Organization (WHO), CBD has a good safety profile.

Besides, it is not addictive, and you won’t be able to overdose on CBD. However, in certain cases, mild effects may occur, such as:

  • Diarrhea
  • Weight loss or gain
  • Change in appetite
  • Fatigue

CBD could also interact with other medications

CBD interacts with liver enzymes and thus may interfere with other substances or drugs metabolized by the liver.

Besides, CBD could also increase the risk of liver toxicity. Cannabidiol can also interfere with other medications used for managing heart disorders, such as blood thinners.

So, it is a good idea to consult your doctor before taking CBD if you are on any medications.
