Cannabidiol (CBD) is a natural compound that may help reduce some factors in high blood pressure, such as stress, anxiety, and poor sleep quality.

This article explores whether CBD can help with high blood pressure, or hypertension, any potential health benefits and risks, which products are available, and some alternatives to CBD.

The Cannabis sativa plant, which people may refer to as marijuana or hemp, contains two main active ingredients, cannabidiol (CBD) and Delta-9-tetrahydrocannabinol (THC).

THC has psychoactive properties, so people may experience euphoria. However, CBD, which comes from the hemp form of C. sativa, only contains small amounts of THC.

Is CBD legal? Hemp-derived CBD products with less than 0.3% THC are legal federally but still illegal under some state laws. Cannabis-derived CBD products, on the other hand, are illegal federally but legal under some state laws. Check local legislation, especially when traveling. Also, keep in mind that the Food and Drug Administration (FDA) has not approved nonprescription CBD products, which may be inaccurately labeled.

Blood pressure is the pressure that the blood exerts against the walls of the arteries. Arteries carry blood from the heart to other parts of the body.

The Centers for Disease Control and Prevention (CDC) state that it is normal for blood pressure to rise and fall throughout the day. However, if an individual’s blood pressure levels are consistently high, they may have hypertension.

A person may not know that they have hypertension because those who have it do not typically experience any symptoms. As a result, healthcare professionals may recommend regularly checking blood pressure.

If a person does not receive diagnosis and treatment, hypertension may lead to other health conditions, such as:

There is some evidence to suggest that CBD may help lower blood pressure.

Doctors may prescribe medications for people with high blood pressure. If an individual is taking blood pressure medications and uses CBD products, it is important they let their doctor know.

What does the research say?

Some research studies indicate that CBD products may help with lowering blood pressure.

A 2020 study found that CBD may have vasodilatory effects in human and rat arteries. The authors suggest that CBD may improve flow because it widens blood vessels.

Additionally, a 2017 study looked at the effects of a single dose of CBD oil in healthy participants. The authors found that it lowered blood pressure in individuals at rest and those under stress.

According to the American Institute of Stress, stress may cause blood pressure to rise. This is due to the heart pumping faster and stress hormones constricting the blood vessels.

However, researchers need to conduct more studies to determine the effect of CBD on cardiovascular conditions.

CBD should not be used to replace prescribed high blood pressure medications. A doctor should be consulted if someone taking this medication chooses to add CBD to their treatment plan.

Risks of CBD

The Food and Drug Administration (FDA) states that there may be some potential risks when using CBD products. These may include:

A 2017 review found that taking CBD with antihypertensive medications may change the blood concentration of either substance. If an individual uses CBD and blood pressure medications, they need to inform their doctor.

CBD and pregnancy

The FDA does not recommend using CBD products during pregnancy or while breastfeeding.

There is not enough research into how CBD may affect a developing fetus. However, there is some evidence, suggesting that high doses of CBD in pregnant test animals may affect a male fetus’s reproductive system.

However, one 2021 study investigating the effects of CBD in pregnant mice found that daily doses of CBD were unlikely to accumulate in the mice and their fetuses.

There needs to be more research to investigate the potential risks of CBD use during pregnancy.

CBD is an exogenous cannabinoid, which means it is a plant-based chemical messenger not produced by the human body. It interacts with the endocannabinoid system, which can strengthen or reduce reactions of the nervous, cardiovascular, digestive, immune, and endocrine systems.

Research shows CBD can have the following effects:

One study of a small group of nine healthy volunteers found that a single dose of CBD reduced resting blood pressure and the blood pressure response to stress. The authors suggested this reaction could be due to the anti-anxiety and pain-relieving qualities of CBD. However, further study is needed.

It is important to note that some people may experience side effects, and CBD can interact with some medications. A person should speak to their doctor before using CBD products.

Some other natural ways to lower blood pressure include:

  • Exercising regularly: The American Heart Association (AHA) states that regular physical activity may help control high blood pressure and strengthen the heart.
  • Learning to deal with stress: Although researchers are still examining the link between stress and hypertension, the AHA notes that people who experience stress may be more likely to have a less healthy diet and drink more alcohol. These dietary factors can increase the risk of high blood pressure.
  • Losing weight, if applicable: A 2016 study found that people with overweight may have an increased risk of high blood pressure.
  • Eating dark chocolate: A 2017 systematic review suggested that eating dark chocolate may cause a small, short-term decrease in a healthy adult’s blood pressure. However, researchers need to conduct more studies to investigate this link.
  • Reducing sodium intake: A 2019 study linked a higher salt intake with high blood pressure and heart disease. People may wish to check nutritional labels for sodium content before consuming a product.

There is no particular type of CBD for lowering blood pressure; further research into the effects of CBD is necessary.

However, the blood absorbs some types of CBD faster than others. How people consume CBD has a significant effect on how quickly the body absorbs it:

  • Capsules and gummies pass through the digestive tract and take 30 minutes to 1 hour to absorb.
  • CBD oils, tinctures, and sprays administered under the tongue typically work in 15-20 minutes.
  • CBD creams and ointments primarily address localized pain, such as swelling or sore muscles, so they would not be an effective choice for people seeking to manage blood pressure.

To find good quality CBD for high blood pressure, look for information on:

  • Independent third-party lab testing: Check that independent labs have reviewed the products to make sure they correctly state the CBD and THC content and do not contain high levels of pollutants. Some companies will post their certificates of analysis, or COAs, on their websites.
  • Extraction method: Manufacturers tend to use high-pressure carbon dioxide gas, chemical solvents, or both to remove CBD from plants. Choosing CBD produced without chemical solvents may be preferable.
  • Where it was grown: Some states, such as Colorado, Oregon, and Kentucky, have active programs supporting and testing hemp, which can help people access more information and better quality products.
  • THC content: THC is the compound in cannabis that makes people feel ‘high,’ and CBD products containing more than 0.3 percent THC have a more complicated legal status. People who want to avoid any chance of intoxication or inter-state purchase problems may prefer products made with lower concentrations of THC. CBD isolate products should not contain any THC.

Some over-the-counter products contain CBD, as well as FDA-approved prescription drugs used to treat seizures in children.

The FDA states that there are risks associated with using CBD, including:

  • interactions with other medications a person may be taking
  • damage to the liver
  • potential risks to people who are pregnant or breastfeeding
  • side effects such as drowsiness, gastrointestinal problems, and mood changes

To use CBD safely, start with a small dosage. Increase the dosage gradually until achieving the desired effect while remaining alert for signs of side effects.

A person should discuss CBD with their doctor before using it.

People with hypertension do not usually have any symptoms, so those with a higher risk may need regular screening.

Healthcare professionals can suggest a treatment plan to help prevent or treat hypertension. For example, they may prescribe medications to help treat hypertension.

A person should consult a doctor before taking any CBD products, as the interaction between these products and certain medications can cause serious side effects.

People who experience side effects from CBD products should cease use and seek medical help immediately.

Below are some of the most common questions and answers about CBD.

What does CBD do to the brain?

CBD stimulates the endocannabinoid system throughout the body and other receptors, such as serotonin receptors. Research has found that CBD enhanced connectivity in parts of the brain in a resting state and supported cognitive activity.

However, according to the FDA, further research into the effects of CBD is necessary, including the effects on the developing brain.

Learn more about serotonin and its function here.

Can you get addicted to CBD?

No. Many studies show that CBD is safe and non-addictive. CBD does not produce the ‘high’ feeling associated with cannabis.

What is the difference between CBD and THC?

CBD and THC are phytocannabinoids, chemical messengers found naturally in the cannabis plant. One of the most important differences is that CBD is not an intoxicating compound, but THC is, and drug tests can identify it.
