Studies show that CBD oil is also beneficial in treating insomnia and post-traumatic stress disorders in children [2] .

Benefits Of CBD Oil On Blood Pressure

CBD oil acts as a holy grail and imparts excellent benefits to patients with blood pressure. Unfortunately, hypertension is one of the growing diseases becoming a significant cause of death in the US. So, CBD comes into action and plays a vital role in controlling the blood level to great extents.

The researchers have suggested that stress and anxiety-reducing properties in CBD play a vital role in controlling blood levels and lowering blood pressure.

The studies [6] on some animals have concluded that CBD might lower the blood pressure that rises in stressful situations and accelerates blood flow after one stroke. The relaxation of blood vessels is carried out through the mechanism of the endocannabinoid system (ECS). ECS is a complicated cell-signaling mechanism discovered by researchers studying THC, a well-known Cannabinoid.

High Blood Pressure: Types & Symptoms

High blood pressure is also known as hypertension, is the pressure in the blood that is higher than the normal pressure. Your blood pressure keeps on changing based on the activities you carry out throughout the day.

Types of High Blood Pressure

There are two types of high blood pressure. The cause of high blood pressure in about 97% of people is unknown, known as primary or essential hypertension. If the individual is diagnosed with the cause of high blood pressure, then this falls under secondary blood pressure.

Essential Hypertension

This type of hypertension is diagnosed by the doctor when you frequently visit them, and on every visit, the blood pressure is above the normal range. Initially, people with essential hypertension will not experience such visible symptoms. Then, however, you may experience headaches, dizziness, and a bleeding nose.

The cause of essential hypertension is still unknown. But the researcher is pretty confident that smoking, alcohol, and obesity play a vital role in essential hypertension.

Secondary Hypertension

The primary and common cause of secondary hypertension is the abnormality in the arteries that supply blood to the kidneys. In addition, airway blockage during sleep, illnesses, tumors of the adrenal glands, hormonal imbalances, thyroid disorders, and a diet high in salt are some of the major causes of secondary hypertension.

Symptoms of Hypertension

So, if you experience any of the following mentioned symptoms, that points directly towards hypertension.

  • Chest Pain
  • Bleeding nose
  • Headaches.
  • Breathing problems.
  • Unclear vision.
  • Fatigue
  • Blood in the urine.

If you experience any of the symptoms [7] , then you need to see a doctor immediately as you need to get the blood pressure under control as soon as possible.

Risk & Side Effects

Hypertension is another word for the increased high blood pressure. High blood pressure in an individual can increase the risk factor for many other diseases. The factors that are responsible for hypertension include:

The risk of hypertension increases with age. People of the age of 60 or above are usually diagnosed with hypertension. This is because the age factor plays a vital role in hypertension. As the person grows older, the arteries stiffen and narrow due to plaque build-up.

Usage of Alcohol and Tobacco

The people addicted to alcohol and tobacco are most at risk of hypertension. The regular consumption of these harmful products can lead to increased blood pressure.

Existing diseases

If a person already has diabetes, kidney issues, cardiovascular diseases, and increased cholesterol, this can certainly lead to hypertension.

The side effects of CBD on hypertension are infrequent; however, CBD and hypertension medication must be combined with great caution and under the doctor’s recommendation. At times, the blood pressure medication slows or reduces the benefits of CBD oil.

How to Use CBD Oil For Hypertension?

There are various ways through which you can consume CBD oil and enjoy its great benefits. CBD oil is available in various formats in the market now; it’s up to you how you would like to have your CBD supplements. Some of the common forms of CBD oil are as follows.

CBD Capsules

If you want to have your CBD oil conveniently, then the CBD oil capsules or other edibles such as brownies and gummies are perfect for beginners. The best thing about this form of CBD oil is that you quickly adjust them in your routine. In addition, the effect of one dose lasts for 6 to 12 hours depending upon your metabolism. So, probably one dose is sufficient for a long day ahead.

CBD oil may take a while before they start showing their effect. This is because the CBD oil has to pass through the digestive system before entering into the bloodstream. So it may take around 20 mins for a capsule to exhibit its effects.

CBD Drops

CD oil or tincture is also a great idea if you are looking for instant or immediate results. The CBD oil or tinctures are placed under the tongue to get absorbed into the bloodstream. Let the CBD oil stay under the tongue for 60 seconds, and after that, swallow the oil. Then, you can place the oil using a dropper under the tongue.

CBD Vapes

One of the fastest ways to get CBD oil absorbed in your body is through CBD vape oils. Since it enters through the lungs into the bloodstream and does not pass through the digestive system, you can notice immediate results. When using CBD in vape form, you can observe its effects within minutes. However, the effect only lasts for 30 minutes to 2 hours.

Final Thought

CBD oil confines itself with numerous benefits, and it’s pretty beneficial for patients with hypertension. There are a variety of CBD oils in the market on which you can get your hands. In addition, the high-quality CBD oil might benefit people with various conditions such as menstrual cramps, blood pressure, seizure, and MS.

Frequently Asked Questions

Some researchers suggest that CBD can help in lowering high blood pressure. According to the 2020 Study [8] , CBD may have vasodilatory effects in human and rat arteries.

W. Christopher Winter, sleep specialist and a medical director of the Martha Jefferson Hospital Sleep Medicine Center says that sleeping on the left side is the best position for patients with hypertension. It provides relief to blood vessels that return blood to the heart.

There is no research that CBD or any other Cannabinoid products help reverse or slow the disease that causes dementia. As per some studies [9] , cannabis can assist in managing the few symptoms of dementia.

For some people under certain prescription medications, using CBD oil can be risky. It can thin the blood as it is packed with anticoagulant effects, and also it can lower the blood pressure as well.

CBD helps in staying focused. CBD has a direct link to dopamine in the brain. You can lessen the risk of irregular fluctuations in dopamine levels by utilizing CBD-rich oils or organic CBD edibles.

This all depends on your body. How much you consume and how you take it. Mostly the effect of CBD lasts for 2 to 6 hours.

Slow and deep breathing activates the parasympathetic nervous system, which lowers blood pressure by lowering heart rate and dilating blood vessels. When you slow down your breathing, your brain associates it with relaxation, causing your body to slow down other operations such as digestion.

Cannabidiol (CBD) oil is an extract from hemp plants called Cannabis indica and Cannabis sativa . You might be more familiar with cannabis plants because they are grown for marijuana. However, CBD is not the same thing as marijuana.

CBD oil contains CBD that’s mixed with a base (carrier) oil, like coconut oil or hemp seed oil. These are called tinctures. You can get tinctures in different concentrations. The oil can also be put into capsules, gummies, and sprays.

People who support using CBD oil say that it can treat pain and anxiety; can help stimulate appetite and may help manage some types of seizures.

This article goes over what CBD is used for, the possible side effects, and what you should look for if you choose to buy CBD.

CBD vs. Marijuana

CBD is one component (called a cannabinoid ) that’s found in a hemp plant. Marijuana is a separate plant but it’s from the same species that hemp belongs to. Marijuana has CBD and hundreds of other compounds in it.

The main difference between hemp plants and marijuana plants is how much of a compound called tetrahydrocannabinol (THC) is in them. Hemp is grown to have less than 0.3% THC, while marijuana has more.

THC is what’s responsible for the psychoactive effects of cannabis—in other words, it’s what makes you feel “high.”

CBD oil generally does not have THC in it; however, a very small (trace) amount might be in products sold in certain states.

What Is CBD Oil Used For?

We’re not sure exactly how CBD works. Unlike THC, CBD doesn’t have a strong connection with the molecules in the brain that THC binds to create psychoactive effects. These are called cannabinoid receptors.

Instead, CBD works on other receptors, like the opioid receptors that help control pain. It also affects glycine receptors that control a brain chemical called serotonin which helps control your mood.

People that support the use of CBD claim that CBD oil can treat a variety of health problems, including:

  • Acne
  • Anxiety
  • Chronic pain
  • Depression
  • Drug use and withdrawal
  • High blood pressure
  • Muscle spasms
  • Poor appetite

As CBD has gained popularity, researchers have been trying to study it more. Still, there has not been a lot of clinical research to look for evidence in support of these health claims.

CBD is not a safe option for everyone. Talk to your healthcare provider if you want to try it for managing a health condition.


A 2015 review of research that was published in the journal Neurotherapeutics suggested that CBD might help treat anxiety disorders.

The study authors reported that CBD had previously shown powerful anxiety-relieving effects in animal research—and the results were kind of surprising.

In most of the studies, lower doses of CBD (10 milligrams per kilogram, mg/kg, or less) improved some symptoms of anxiety, while higher doses (100 mg/kg or more) had almost no effect.

The way that CBD acts in the brain could explain why this happens. In low doses, CBD might act the same as the surrounding molecules that normally bind to the receptor that “turns up” their signaling.

However, at higher doses, too much activity at this receptor site could produce the opposite effect.

There have not been many trials to look at CBD’s anxiety-relieving effects in humans. However, one was a 2019 study published in the Brazilian Journal of Psychiatry.

For the study, 57 men took either CBD oil or a sugar pill with no CBD in it (placebo) before a public-speaking event.

The researchers assessed the participants’ anxiety levels using measures like blood pressure and heart rate. The researchers also used a reliable test for mood states called the Visual Analog Mood Scale (VAMS).

The men who took 300 mg of CBD oil reported less anxiety than the men who were given a placebo; however, the men who took 100 mg or 600 mg of CBD oil did not experience the same effects.


CBD oil might help people with substance use disorder, according to a 2015 review published in the journal Substance Abuse.

The review looked at the findings from 14 published studies. Nine of the studies looked at the effects of CBD on animals, and five studies looked at the effects on humans.

The researchers reported that CBD showed promise for treating people with opioid, cocaine, or psychostimulant use disorders.

However, the effects of CBD were quite different depending on the substance. For example, CBD without THC did not decrease withdrawal symptoms related to opioid use.

On the other hand, it did reduce drug-seeking behaviors in people using cocaine, methamphetamine, and other similar drugs.

Some experts suggest that CBD could help treat cannabis and nicotine dependence, but more research is needed to provide this theory.

High Blood Pressure

A 2017 study found that CBD oil may reduce the risk of heart disease because it can lower high blood pressure in some people.

For the study, nine healthy men took either 600 mg of CBD or the same dose of a placebo. The men who took CBD had lower blood pressure before and after experiencing stressors like exercise or extreme cold.

The study also looked at the amount of blood remaining in the heart after a heartbeat (stroke volume).

The stroke volume in the men who took CBD was lower than in was in the placebo group, meaning their hearts were pumping more efficiently.

The study suggested that CBD oil could be a complementary therapy for people with high blood pressure that is affected by stress and anxiety.

However, there is no evidence that CBD oil can treat high blood pressure on its own or prevent it in people at risk. While stress can complicate high blood pressure, it does not cause it.


In June 2018, the U.S. Food and Drug Administration (FDA) approved a CBD oral solution called Epidiolex.

Epidiolex is used to treat two rare forms of epilepsy in children under the age of 2: Dravet syndrome and Lennox-Gastaut syndrome. These are very rare genetic disorders that cause lifelong seizures starting in the first year of life.

Other than for these two disorders, CBD’s effectiveness for treating seizures is not known. Even with Epidiolex, it’s not clear if the anti-seizure effects are from CBD or another factor.

However, there is some evidence that CBD interacts with seizure medicines like Onfi (clobazam) and raises their concentration in the blood. That said, more research is needed to understand the link.

Possible Side Effects

Clinical research has shown that CBD oil can cause side effects. The specific side effects a person has and how bad they are varies from one person to the next and from one type of CBD to another.

Some common side effects people report from using CBD include:

  • Anxiety
  • Changes in appetite
  • Changes in mood
  • Diarrhea
  • Dizziness
  • Dry mouth
  • Nausea
  • Vomiting

CBD oil may also increase liver enzymes, which is a marker of liver inflammation.

People with liver disease should talk to their healthcare provider before taking CBD oil. They may need to have their liver enzymes checked regularly if they are using CBD.

Can You Use CBD If You’re Pregnant?

You should not use CBD oil if you’re pregnant or breastfeeding. Even though the effects of CBD are not fully understood, it does pass through the placenta.

The American Academy of Pediatrics (AAP) further states that pregnant people should not use marijuana because of the potential risks to a developing fetus.

Do not drive or use heavy machinery when taking CBD oil—especially when you first start using it or switch to a new brand. Remember that some products do contain THC, even in small amounts.


CBD oil can interact with medications, including many that are used to treat epilepsy. One of the reasons for this has to do with how your body breaks down (metabolizes) drugs.

Cytochrome P450 (CYP450) is an enzyme your body uses to break down some drugs. CBD oil can block CYP450. That means that taking CBD oil with these drugs could make them have a stronger effect than you need or make them not work at all.

Drugs that could potentially interact with CBD include:

  • Anti-arrhythmia drugs like quinidine
  • Anticonvulsants like Tegretol (carbamazepine) and Trileptal (oxcarbazepine)
  • Antifungal drugs like Nizoral (ketoconazole) and Vfend (voriconazole)
  • Antipsychotic drugs like Orap (pimozide)
  • Atypical antidepressants like Remeron (mirtazapine)
  • Benzodiazepine sedatives like Klonopin (clonazepam) and Halcion (triazolam)
  • Immune-suppressive drugs like Sandimmune (cyclosporine)
  • Macrolide antibiotics like clarithromycin and telithromycin
  • Migraine medicine like Ergomar (ergotamine)
  • Opioid painkillers like Duragesic (fentanyl) and alfentanil
  • Rifampin-based drugs used to treat tuberculosis

Always tell your healthcare provider and pharmacist about all the medicines you take, including prescription, over-the-counter (OTC), herbal, or recreational drugs.

The interactions between these medications and CBD are often mild and you might not have to change your treatment.

However, in some cases, you might have to change medications or space out your doses to avoid a reaction. That said, never change or stop medication without talking to your provider.

Dosage and Preparation

There are no guidelines for using CBD oil. Each product works a bit differently, depending on the form.

For example, putting the oil under your tongue can produce effects more quickly than swallowing a capsule that needs to be digested.

Here are a few ways that you can take CBD oil:

  • Placing one or more drops under your tongue and holding it there for 30 to 60 seconds without swallowing. You can also use a spray that is spritz in your mouth/under your tongue.
  • Taking a capsule or chewing a gummy

There’s no “correct” dose of CBD oil. How much you take and the form you choose will depend on your needs and what you hope to get for effects. The average dose range is from 5 mg to 25 mg.

Most oils come in 30-milliliter (mL) bottles and include a dropper cap to help you measure.

That said, it’s hard to figure out the exact amount of CBD per milliliter of oil. Some tinctures have concentrations of 1,500 mg per 30 mL, while others have 3,000 mg per mL or more.

How to Calculate CBD Dose

To determine an exact dose of CBD, remember that each drop of oil equals 0.05 mL of fluid. This means that a 30-mL bottle of CBD oil will have about 600 drops in it.

If the concentration of the tincture is 1,500 mg per mL, one drop would have 2.5 mg of CBD in it. The math to figure that out looks like this: 1,500 mg ÷ 600 drops = 2.5 mg

What to Look For

CBD oil comes in different forms: isolates, broad-spectrum, and full-spectrum.

  • Isolates contain only CBD
  • Broad-spectrum oils nearly all of the components of the plan (e.g., proteins, flavonoids, terpenes, and chlorophyll), but does not have THC oils have all the compounds including THC (up to 0.3%)

Alternative medicine practitioners believe that the compounds provide more health benefits, but the is a lack of evidence to support these claims.

Remember that CBD oils are unregulated. There’s no guarantee that a product is what it claims to be on its packaging. You also can’t know for sure that it’s safe and effective.

If you are interested in buying CBD products, here are a few tips to keep in mind:

  • Buy American: Domestically produced CBD oil might be a safer option than those that have been imported.
  • Go organic: Brands certified organic by the U.S. Department of Agriculture (USDA) are less likely to expose you to pesticides and other harmful chemicals.
  • Read the product label: Even if you choose a full-spectrum oil, don’t assume that every ingredient on the product label is natural. CBD products can also have preservatives, flavorings, or thinning agents in them. If you don’t recognize an ingredient, ask the dispenser what it is or check online.

You should also know that the products are not regulated, which means you can’t know for sure that a product will work and be safe.

Before you use CBD oil, talk to your provider. If you take certain medications or have a health condition, you may not be able to use these products.
