CBD oil is made from cannabis plants but won’t make you high. Still, this natural supplement could interact with some heart medicines. Find out what you need to know before you try CBD oil for heart failure. CBD has been shown to slow down the progression of many conditions that lead to heart failure. Let’s find out how it works and how to use it effectively. Heart Disease Cardiovascular disease typically refers to narrowed or blocked blood vessels. Other heart conditions can affect the heart’s muscle, valves or rhythm. Symptoms may include fatigue,
CBD Oil and Heart Failure
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.
“Heart failure patients should know that while CBD has been touted as a wonder compound and seems to be in almost everything these days, it has never been shown to have any significant cardiovascular benefits in human studies,” says Scott Lundgren, DO, a transplant cardiologist at Nebraska Medicine in Omaha.
What Is CBD Oil?
CBD oil contains cannabidiol, an herbal liquid supplement made from the cannabis plant. It doesn’t have the same effect on the brain as THC, another compound found in cannabis that gives you a “high” when smoked or eaten, says Larry Allen, MD, associate division head for clinical affairs in cardiology at University of Colorado Anschutz Medical Campus.
“There are no known cardiovascular benefits for cannabis or cannabidiol, and there may even be some adverse effects, so people should not take these products and think that it will have positive effects on their cardiovascular health,” says Allen, who’s also co-author of the American Heart Association’s statement on all cannabis products.
In 2018, the FDA approved the first oral, purified CBD drug, Epidiolex, to treat seizures in two rare forms of epilepsy. Two synthetic versions of cannabiinds are also approved: dronabinol (Marinol, Syndros) for treatment of nausea during cancer chemotherapy and nabilone (Cesamet) to treat weight loss associated with AIDS. Marinol is synthetic THC
Some of CBD’s proven benefits in other health conditions may be intriguing to people living with heart failure, Allen says.
“Does it stimulate your appetite? Yes. Do people gain weight if they take it? Possibly true. Patients with severe heart failure do have cachexia,” or severe weight loss and muscle wasting, he says. “One could argue that people with nausea, lack of appetite, or who are losing weight could think CBD would help them. People with heart failure have a fair amount of discomfort, including edema [swelling] and somatic or pain-related issues, so you could think CBD has a role.”
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.
What We Know About CBD
Some research suggests that CBD oil may improve some heart-related symptoms:
- A very small study conducted in 2017 in England found that CBD improved resting blood pressure and blood pressure spikes related to stress in people without heart conditions.
- Various studies in animals have shown that CBD could improve vasorelaxation, or opening of arteries for better blood flow, as well as reduce inflammation. A small clinical trial from Mexico studying CBD in people with heart failure hasn’t reported any results yet.
- A large study of more than 161,000 people hospitalized for heart failure who had used marijuana found that they had, on average, a lower risk of death and shorter hospital stays. But this doesn’t necessarily mean CBD oil would have the same benefit.
It’s illegal in the U.S. to market CBD by adding it to any food or calling it a dietary supplement. Also, although the FDA has approved a few CBD drugs to treat certain diseases, don’t expect CBD sold over the counter to be safe or beneficial for heart failure, 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.
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 May Have Health Risks
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.”
If you have heart failure, you might feel like you’re taking control of your own care by trying herbal treatments that don’t require a prescription. To be safe, talk to your cardiologist first: Ask questions about CBD oil and make decisions together about using this or any other supplement, Allen says.
“CBD products cost money and can distract you from taking prescribed treatments for heart failure that are evidence-based. They could do indirect harm to people with heart failure. . We already have a half-dozen treatments for heart failure symptoms and to help you live longer.”

CBD and Congestive Heart Failure: Can It Help?
In the United States, around 655,000 people die each year from heart failure.
That’s a lot of people.
As with most things, prevention is better than a cure. CBD isn’t the cure for congestive heart failure, but studies suggest it may help prevent it.
So, how can CBD help, and what’s the best type of CBD for preventing congestive heart failure (CHF)?
Can CBD Prevent Congestive Heart Failure?
Congestive heart failure happens after many years of blocked arteries, high blood pressure, or damaged chambers. This can be caused by a number of different health issues, the main of which are listed above.
CBD can help prevent congestive heart failure by treating a number of the conditions raised earlier. If these conditions can be controlled, the risk of heart failure can be decreased.
It’s not 100% clear if CBD will help prevent heart failure completely. However, several benefits may help in conjunction with lifestyle changes, and in some cases, other medications.
It’s important to note that CBD may interact with prescription and over-the-counter medications, so you should always consult your doctor before using CBD to treat a condition that could lead to congestive heart failure.
If you’re suffering from obesity, diabetes, heart disease, or high blood pressure, CBD may help reduce symptoms and even aid in getting better. This could be a huge factor in reducing the chances of heart failure.
What is Congestive Heart Failure?
Congestive heart failure, also known simply as heart failure, occurs when the heart cannot pump enough blood around the body.
Certain conditions and diseases can leave the heart too weak or stiff to pump blood effectively. This will eventually lead to a heart attack.
The Symptoms of Congestive Heart Failure
There are a number of early warning signs for heart failure. Below are some of the more common symptoms leading up to CHF:
- Extreme fatigue & weakness
- Rapid or irregular heartbeat
- Shortness of breath
- Difficulty exercising
- Persistent cough with bloody phlegm
- Abnormal weight gain from fluid retention
- Reduced appetite & nausea when eating
- Brain fog and difficulty concentrating
- Edema (swelling in the legs, ankles, and feet)
- Chest pains
It’s important to note that these symptoms do match up with other conditions and are considered normal in some circumstances.
Don’t overthink if you’re experiencing one or two of these symptoms mildly, but make sure to check with your doctor if you’re concerned about your heart health. It’s better to be safe than sorry.
What Causes Congestive Heart Failure?
There are several conditions that can eventually lead to heart failure.
Some of these conditions are incurable but the risk of heart failure can be decreased. Some other conditions that can potentially lead to heart failure are curable and can be defeated with a few simple lifestyle changes.
Below are some of the more common conditions that are associated with heart failure.
1. Heart Disease
Heart disease is a broad term that categorizes a number of preventable and unpreventable heart conditions.
Some types, such as congenital heart defect, are genetic defects of the heart that are present for life. This can include abnormal heart valves, septal defects (holes in the heart’s chambers), and atresia (a missing heart valve).
Coronary artery disease is the most common type of heart disease. The arteries that supply blood to the heart can become clogged with plaque, causing them to narrow and reduce the efficiency of the heart.
In some people, coronary artery disease is preventable and curable with some lifestyle changes. For others, it’s something that must be treated for life.
Arrhythmia is when a person has an irregular heartbeat. When the electrical impulses that coordinate the muscle’s pumping function don’t work properly, the heartbeat can become irregular or pump too fast or slow.
Dilated cardiomyopathy is where the heart’s chambers become dilated. With dilated chambers, the heart becomes weaker and struggles to pump blood properly. This type of heart disease usually comes prior to heart attacks and arrhythmia.
If left untreated, heart disease can lead to heart attack and heart failure.
2. High Blood Pressure (Hypertension)
High blood pressure, also known as hypertension, is where your blood pressure is higher than normal.
High blood pressure strains the heart and other organs. When you have hypertension, your heart works overtime to pump blood around your body.
The higher your blood pressure, the more risk you face for other conditions and health issues. Left untreated, high blood pressure can lead to heart disease, stroke, or a heart attack.
Put simply, diabetes affects how your body processes food into energy. It’s a chronic health condition that can be treated and controlled but has no cure.
When you eat a meal, most of the food is broken down into glucose (sugar) that is then released into the bloodstream. When blood sugar levels rise, the pancreas releases insulin to help the body use the glucose as energy.
Diabetes sufferers either don’t produce enough insulin (if any at all) or can’t utilize the insulin in the same way as a normally functioning body.
When the body has a lack of insulin or the insulin present isn’t functioning as it should, glucose can build up in the bloodstream. Over time, the excess glucose, if left untreated, can cause serious health issues including eventual heart failure.
Over 40% of the U.S population is considered obese. It comes primarily from over-eating. Obesity is mostly preventable and if you’re suffering from obesity, with the right lifestyle changes, you can combat it.
You’re considered obese when your BMI is over 30.
Subcutaneous fat is visible fat. It forms under the skin all over the body with the most common areas affected consist of the hips, buttocks, and abdominal region.
Visceral body fat (also known as hidden fat) is much more dangerous. It’s stored deep inside the belly and around the organs. It’s this fat that causes the most health implications.
Obesity puts a strain on all of your organs and the excess fat around your heart can lead to serious health issues.
Obesity can lead to heart disease, and eventually, heart attack and heart failure.
What are the Benefits of CBD for Congestive Heart Failure?
So, what are the potential benefits of CBD for congestive heart failure?
As mentioned, CBD alone isn’t going to prevent heart failure, but it can be used to treat some conditions that could lead to it.
1. CBD May Regulate Blood Sugar Levels
There is evidence that suggests some cannabinoids, including CBD, can help regulate blood sugar levels and help resolve diabetic complications .
Although the cannabinoid THC seems to regulate blood sugar more effectively than CBD, full-spectrum oil may have the same desired effect.
Lowering blood sugar levels will help reduce the damage caused by diabetes. This could be what prevents congestive heart failure in a diabetic patient.
2. CBD Helps to Fight Obesity
CBD can aid in weight loss.
Some studies suggest that supplementing a weight loss routine with CBD can help shed excess pounds . CBD promotes the browning of white fats, which makes it easier to convert the fat into burnable calories.
Obesity is one of the leading causes of congestive heart failure. If you’re obese, losing weight is essential in enhancing your health and reducing the risk of many health complications — including congestive heart failure.
3. CBD Decreases Inflammation
CBD is renowned for its anti-inflammatory benefits. This desirable trait could help prevent heart failure in the long term.
Diabetes and heart disease can cause damage to the walls of the blood vessels. This damage can cause inflammation. One study found that glucose-triggered inflammation can be relieved by CBD .
Inflamed blood vessels make it harder for the heart to pump blood around the body. Reducing this inflammation will help ease the strain on the heart, ultimately preventing further damage and potential heart failure.
4. CBD Lowers Blood Pressure
CBD lowers blood pressure.
Studies suggest that even low doses of CBD can significantly lower blood pressure .
High blood pressure (hypertension) has been directly linked to congestive heart failure. Reducing blood pressure and keeping it down consistently will help prevent congestive heart failure in the long term.
How to Use CBD For Congestive Heart Failure?
Using CBD to lose weight, control blood sugar levels, lower blood pressure, or decrease inflammation may help prevent congestive heart failure.
How you use CBD for congestive heart failure will affect the results you get. Choosing the right CBD product is vital to reaping the rewards that this cannabinoid sows.
It’s important to note that you shouldn’t use CBD alone to treat certain health conditions. A combination of lifestyle changes and other medications may be needed to get on top of some conditions.
1. Full-Spectrum, Broad-Spectrum, or Isolate?
You may have heard the terms isolate, broad-spectrum, and full-spectrum, but what’s the difference? And which is best for congestive heart failure?
CBD isolate is a pure extract of the cannabinoid CBD (cannabidiol). Oils, edibles, and topicals that are made using isolate contain only CBD with no other cannabinoids or terpenes present.
CBD isolates are great if you want to avoid THC or any other cannabinoids entirely. They’re perfect for people that react badly to other cannabinoids and they have no chance of showing up on a drug test.
The only downside is you won’t get the full entourage effect as you would with a full-spectrum product. Research suggests that CBD is more effective when consumed as part of a full cannabinoid profile .
Broad-spectrum products contain CBD as well as a wide range of other cannabinoids.
Broad-spectrum oils, edibles, and topicals contain a cannabinoid profile similar to what’s in the raw hemp flower. The only cannabinoid that broad-spectrum products don’t contain is the psychoactive cannabinoid THC.
Broad-spectrum CBD is perfect for people that want to reap the benefits of the entourage effect without consuming THC. Broad-spectrum products have no chance of showing up on drug tests.
Full-spectrum CBD products contain a full cannabinoid profile. They have an identical profile to the raw hemp flower including THC in percentages lower than 0.3%.
This type of CBD is the most valuable to use for multiple health conditions and holds the most potential for preventing congestive heart failure. This is because it provides the full entourage effect.
Full-spectrum oils and edibles have THC levels that are too low to provide a “high”, but depending on how much you’re consuming, they may show up on drug tests.
2. CBD Consumption Method
There are many ways to consume CBD. Some are better than others for treating conditions that are associated with congestive heart failure. It’s important to know which products are best.
You will find all of these CBD products in isolate, broad-spectrum, and full-spectrum options.
CBD oil provides you with the most flexibility in terms of dosage. It’s also one of the best ways to consume CBD for heart failure because it’s highly bioavailable and has few additives that will trigger any undesirable effects.
You can add drops directly under the tongue or supplement meals and drinks by adding a few drops into your meal routine.
CBD edibles come in many forms. You’ll find CBD-infused honey sticks, gummies, lollipops, and more.
Edibles are fantastic if you can’t stand the taste of raw CBD oil. However, they’re not ideal for treating some conditions related to congestive heart failure.
Because of the high sugar content, you should avoid CBD edibles if you have diabetes or are struggling with obesity.
Technically edible, capsules give you a tasteless way to consume CBD without the sugar found in chewable edibles.
Capsules provide you with an accurate dosage per capsule and medicating is as easy as swallowing a pill.
CBD capsules are a great option for congestive heart failure because they contain no sugar and are relatively bioavailable.
Topicals are CBD products such as gels, creams, and balms that can be applied directly to the skin.
Although they’re great if you’re suffering from a skin condition, they pose no real value for conditions that are related to heart failure.
CBD vape liquid is heated up and inhaled as a vapor. Using CBD in this way provides maximum bioavailability as it absorbs lung tissue quickly and efficiently.
Unfortunately, there’s little known about the negative effects of vaping CBD, so if you’re suffering from a severe health condition it isn’t the first consumption method you should look at.
3. CBD Dosage for Heart Failure
CBD works differently from person to person.
The right dosage for one person won’t be correct for another, so there is some level of self-experimentation needed to find out what’s right for you.
Generally speaking, a dose between 20 and 100-milligrams per day will be effective for most conditions but it could be significantly higher or lower depending on your body weight, metabolism, and age.
As with most supplements, you should start with a low dose and work your way up until you find out what’s effective for you.
If you’ve never used CBD before it’s especially important that you test the waters with a low potency product at a low dose to find out how your body reacts to the cannabinoid.
Once you’re sure there are no negative effects, you can increase the dosage slowly until you get the desired effects.
Make sure you consult your doctor before using CBD to supplement other medications for your condition.
Final Thoughts: Can CBD Help Prevent Congestive Heart Failure?
In short, yes CBD can help prevent congestive heart failure.
CBD can help with weight loss, diabetes, heart disease, and high blood pressure. Controlling these conditions may reduce the chances of heart failure.
If you’re looking at CBD as a treatment for congestive heart failure it’s important to first speak with your doctor. CBD may negatively impact other medications and treatments, so it’s of paramount importance you seek professional advice.
When looking for the best CBD product for your condition, we advise you to research the brand and check the independent lab reports. This way, you’ll be certain you’re receiving the best possible treatment.
