Cannabidiol (CBD) is a chemical in the Cannabis sativa plant, also known as cannabis or hemp. One specific form of CBD is approved as a drug in the U.S. for seizure.
Over 80 chemicals, known as cannabinoids, have been found in the Cannabis sativa plant. Delta-9-tetrahydrocannabinol (THC) is the most famous ingredient in cannabis. But CBD is obtained from hemp, a form of the Cannabis sativa plant that only contains small amounts of THC. CBD seems to have effects on some chemicals in the brain, but these are different than the effects of THC.
A prescription form of CBD is used for seizure disorder (epilepsy). CBD is also used for anxiety, pain, a muscle disorder called dystonia, Parkinson disease, Crohn disease, and many other conditions, but there is no good scientific evidence to support these uses.
Laws passed in 2018 made it legal to sell hemp and hemp products in the US. But that doesn’t mean that all CBD products made from hemp are legal. Since CBD is an approved prescription drug, it can’t be legally included in foods or dietary supplements. CBD can only be included in “cosmetic” products. But there are still CBD products on the market that are labeled as dietary supplements. The amount of CBD contained in these products is not always the same as what is stated on the label.
How effective is it?
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
The effectiveness ratings for CANNABIDIOL (CBD) are as follows:
Likely effective for.
- Seizure disorder (epilepsy). A specific prescription product (Epidiolex, GW Pharmaceuticals) is approved by the US FDA to treat seizures caused by Dravet syndrome, Lennox-Gastaut syndrome, or tuberous sclerosis complex. It is unclear if other forms of CBD are helpful for seizure. For now, stick with the prescription product.
Is it safe?
When taken by mouth: CBD is possibly safe to take in appropriate doses. Doses of up to 200 mg daily have been used safely for up to 13 weeks. With the guidance of a healthcare provider, a specific prescription CBD product (Epidiolex) has been used at higher doses and for longer durations.
CBD can cause some side effects, such as dry mouth, low blood pressure, light headedness, and drowsiness. Signs of liver injury have also been reported with high doses of the prescription form of CBD, called Epidiolex.
When applied to the skin: There isn’t enough reliable information to know if CBD is safe or what the side effects might be.
Special precautions & warnings:
Pregnancy and breast-feeding: It may be unsafe to take CBD if you are pregnant or breast feeding. CBD products can be contaminated with other ingredients that may be harmful to the fetus or infant. Stay on the safe side and avoid use.
Children: It is possibly safe for children to take a specific prescription CBD product (Epidiolex) by mouth in doses up to 25 mg/kg daily. This product is approved for use in children with certain conditions who are at least 1 year old. It isn’t clear if other CBD products are safe in children.
Liver disease: People with liver disease may need to use lower doses of CBD.
Parkinson disease: Some early research suggests that taking high doses of CBD might make muscle movement and tremors worse in some people with Parkinson disease.

CBD Oil for High Blood Pressure in 2022
Hypertension is a serious condition affecting 33% of US adults above the age of 20. This figure is twice as high for people in their mid-60s and over.
It goes without saying that high blood pressure is becoming a pandemic, which is only going to get worse if people continue to live unhealthy lives full of stress, processed food, and low physical activity.
If you’re reading this, chances are that you, too, have been diagnosed with high blood pressure. The good news is that hypertension doesn’t strike immediately like other serious conditions — so the sooner you act, the better.
While there’s already a large body of scientific research into hypertension, there are no surefire methods that would work for every individual. But thanks to the rise of natural alternatives like CBD oil, many people now assume that cannabis-based products could provide relief from high blood pressure in modern society.
If you’re wondering whether you can use CBD oil for high blood pressure, this article is for you. Below you’ll find my most trusted brands that sell high-quality CBD oil. I’m also going to cover the latest research highlights regarding the effects of CBD on blood pressure.
Best CBD Oils for High Blood Pressure
If you’ve been thinking about CBD oil as your potential hypertension treatment, you’ve probably come across many different brands and products.
The choice may be overwhelming for new consumers, but the key to success is to find a trusted manufacturer that will use organic hemp plants and butane-free extraction methods. The company of your choice should also post lab reports for each product it sells as proof of quality.
All that said, I trust these three brands enough to recommend them for anyone looking for a natural way to improve their quality of life.
1. Royal CBD
Get 15% off all Royal CBD products. Use code “CFAH” at checkout.
- Royal CBD uses Colorado-grown organic hemp
- The company makes its products using a supercritical CO2 extraction.
- They offer both full-spectrum and isolate-based products
- The oil is very potent — up to 83.3 mg in each mL
- Every batch of product has been tested for potency and purity in a third-party laboratory
- No vape oils available yet
- These products are more expensive than other brands, but that’s justified by the quality of ingredients
My Thoughts on Royal CBD:
Launched in 2018 by a group of cannabis aficionados, Royal CBD is a premium manufacturer of hemp-derived CBD products. The company’s philosophy revolves around simplicity and the quality of ingredients. Their CBD oil is sourced from organic hemp grown by American farmers who prefer to cultivate their crops without pesticides and chemical fertilizers.
Royal CBD offers CBD in its most common forms, including sublingual drops, capsules, and edibles. All of their products are extracted using pressurized CO2, a technique that yields clean and potent extracts.
The Royal CBD oil comes in three different strengths:
It’s a full-spectrum extract, so you get CBD along with other cannabinoids and terpenes naturally occurring in hemp. Experts believe full-spectrum extracts to be more effective in certain conditions when compared to isolated CBD.
Royal CBD regularly tests its products in a 3rd-party laboratory for their cannabinoid profiles and to make sure they are free of contaminants.
If you dislike the taste of natural CBD oil, you may want to try Royal CBD capsules. These are quite potent, too, as each softgel carries 25 mg.
2. Gold Bee (Best Organic CBD Oil)
- Unique product selection
- Gold Bee uses non-GMO, Colorado-grown hemp
- The oil contains full-spectrum CBD
- The company’s products are extracted with CO2
- You’re getting up tp to 1200 mg of CBD per bottle
- The oil is sweetened with organic honey
- Third-party lab tested for potency and purity
- No high-strength oils
- Not available in-store
What I Like About Gold Bee:
Gold Bee was launched in 2019 in California by a group of cannabis enthusiasts who earlier operated on the superfoods market. Gold Bee offers an unusual product line up, including full-spectrum honey-sweetened CBD oil and CBD-infused honey sticks and gummies. All Gold Bee’s products are made from organic hemp and tested for potency and purity in a third-party laboratory.
I couldn’t help but try the 1200 mg kiwi-flavored CBD oil as I was curious about the taste of full-spectrum CBD that is sweetened with organic honey. The flavor was spot-on, but what surprised me the most was the very calming effect it had on my body. This was unusual for me because I’ve tried some higher-potency oils in my life and the stress-relieving effects weren’t as good as with this brand.
If you’re looking for a risk-free way to check out Gold Bee’s products, you can use its 30-day money-back guarantee and get a full refund for your order if you’re not satisfied with the results.
- CBDPure makes full-spectrum CBD oil
- The company uses CO2 for extraction
- All products are sent to a 3rd-party laboratory for a content analysis
- You can send your order back for a full refund within 90 days as part of CBDPure’s 100% Satisfaction Guaranteed program
- Narrow product selection
- Lower potency than Royal CBD
My Thoughts on CBDPure:
One thing I particularly appreciate about CBDPure is the company’s transparency. CBDPure openly shares every detail of their activity, from sourcing to packaging. They also provide a Certificate of Analysis for each batch of their oils and capsules.
CBDPure has a modest product selection, offering only full-spectrum oil drops and softgel capsules. The oil is less potent than other brands in this ranking, but the company sells it in larger bottles, so if you benefit from low doses, you may get supplied for a couple of months.
For stronger effects, you may try CBDPure’s softgels which carry 25 mg of CBD per capsule. And, if you end up unsatisfied with your product, you can send the order back within 90 days and receive a full refund.
- CBDistillery uses locally grown hemp
- The company’s products are available as full-spectrum or isolate
- Impressive product selection
- Each batch is tested in a 3rd-party lab for potency and purity
- CBDistillery is one of the most affordable brands on the market
- The hemp used by CBDistillery isn’t organic
- The CBD oil is available only in the unflavored option
My Thoughts on CBDistillery:
CBDistillery is one of the industry’s trailblazers. This company has been offering high-quality CBD oil products for over 5 years now on top of providing education for its customers under the #CBDMOVEMENT hashtag.
CBDistillery has plenty of different CBD products in its collection, from sublingual drops to capsules, topicals, gummies, and vapes. The company’s CBD oil comes as full-spectrum or CBD isolate.
These oils are available in two different sizes — 15 mL and 30 mL. The potency of the 15 mL bottle ranges between 150–1,000 mg of CBD, whereas the 30 mL bottle offers 2,500–5,000 mg.
With such a broad potency range, CBDistillery oil is good for both new consumers and seasoned users alike. The only disadvantage of the company’s product lineup is that they’re not made with organic hemp.
However, once you consider the price of CBDistillery products, you’ll understand why I’ve decided to choose this brand as my third favorite. CBDistillery might not sell the best CBD oil on the market, but they definitely offer the best CBD oil in this price range.
What Is High Blood Pressure (aka Hypertension)?
Blood pressure is measured by the amount of pressure applied by blood flow onto the internal system of arteries in the human body.
This pressure tends to go up and down throughout the day as your body reacts to environmental, physical, and emotional stimuli.
Although the changes in blood pressure can be frequent, there’s a specific range the pressure needs to stay within in order to maintain optimal health.
The Centers for Disease Control (CDC) reports that about one-third of American adults have blood pressure that consistently exceeds the normal range. This condition of consistently high blood pressure is known as hypertension — it can have a series of negative consequences on your health.
Hypertension is the most common cause of cardiovascular disease. As noted by the CDC, high blood pressure was responsible for 410,000 deaths in 2014 alone. In addition, hypertension and its collateral damage are estimated to cost Americans up to $50 billion each year.
What Are the Symptoms of High Blood Pressure?
How do you know if you have hypertension?
The problem with this condition is that it may not give you as many negative symptoms as other diseases, so sometimes, it may be extremely difficult to diagnose hypertension at home.
If you want to prevent hypertension or detect it in its infancy, you should always schedule regular appointments with your physician to monitor blood pressure.
The symptoms below indicate that you need to make an appointment at your local medical center as soon as possible:
- Frequent, severe headaches
- Permanent fatigue
- Problems with vision
- Changes in heartbeat
How Is Hypertension Treated?
As with any chronic condition, pharmaceuticals are the treatment of choice for most people. As much as I agree that they pull blood pressure numbers back into the normal range, I’m not a fan of prescription or OTC medications because these come with their own set of side-effects.
Some of them may even worsen your condition because they can cause muscle weakness, fatigue, lightheadedness, and electrolyte deficiencies.
As a matter of fact, one of the most important measures you can take to lower blood pressure is to reach the cause of your hypertension. You need to incorporate some radical lifestyle changes. Diet, exercise, and stress management can contribute to lower blood pressure and, at the same time, prevent the side effects of hypertension.
These changes, require time and commitment to receive any benefits.
How Could CBD Lower Blood Pressure?
Research shows that supplementation with CBD may be effective in reducing blood pressure in healthy adults, thus decrease the risk of atrial fibrillation. CBD may also mitigate negative changes in the pressure caused by various triggers.
This may mean a lot for hypertension patients who are in search of alternative ways to manage their symptoms and bring their blood pressure back to the normal range.
There haven’t been many trials that would test the effectiveness of CBD in chronic hypertension, so while the current findings are promising, CBD still isn’t an approved form of hypertension treatment.
Scientific Research on CBD and Blood Pressure
If you’re interested in using CBD oil for high blood pressure, read on to explore the latest scientific findings.
1. CBD May Inhibit Stress-Induced Blood Pressure Changes
In a 2019 study, Brazilian researchers investigated the effects of several different CBD doses on anxiety levels caused by public speaking.
They tested the following dosages:
Anxiety can be measured with telltale signs such as increased heart rate and blood pressure. The data from this study showed that the medium dose of CBD produced a notably improved stress response to giving a speech, giving us an indirect look at the effects of CBD on blood pressure.
The study can also serve as a reference point for drafting out dosage guidelines for CBD oil and hypertension.
2. CBD Acts as a Vasodilator
As noted in a 2017 randomized crossover study, a single dose of cannabidiol reduced blood pressure in healthy subjects, specifically in male adults.
Starting from their regular blood pressure range, the participants were asked to engage with two different types of stressors — exercise and cold. These stressors are known to cause a vivid increase in blood pressure.
While the subjects who took CBD prior to exposure to these stressors still experienced a rise in blood pressure, it was much lower than that shown by the placebo group.
The researchers concluded that CBD may be an effective compound in stress management by lessening the body’s reaction to various stressors and thus potentially reducing the risk of side effects caused by hypertension.
3. CBD May Lower Heart Rate
In a 2009 study, rats were put under a stressful situation that caused their blood pressure and heart rate to increase. A single dose of CBD lowered both their blood pressure and heart rate. While more human research is needed to make conclusive claims, CBD may have the potential to lower heart rate under stress.
However, a 2017 review of 25 studies found that there’s no link between CBD and reduced heart rate under non-stressful conditions.
Potential Risks of Using CBD Oil for High Blood Pressure
While the early findings on the effects of CBD for high blood pressure are optimistic, people who already use certain medications for hypertension should absolutely consult with their doctor before buying any CBD product.
That’s because CBD oil can interact with these medications and cause blood pressure to drop too low — and too low isn’t good either.
People using CBD oil derived from marijuana may experience an acute, dose-dependent increase in blood pressure and heart rate shortly after consumption, but that’s caused by the THC in those products.
The increase in blood pressure and heart rate is then followed by a modest hypotensive effect — a decrease in blood pressure.
Hemp-derived CBD oil usually has less than 0.3% and thus can’t induce such effects. Other than the aforementioned drug interactions, CBD oil comes with a few mild side effects such as the dry mouth and appetite suppression.
What’s the Best CBD Oil Dosage for High Blood Pressure?
If you’re looking for a one-size-fits-all dosage, you’ll be deeply disappointed because dosing CBD depends on many different factors.
The list includes your age, weight, metabolism, prior experience with CBD, and the severity of your symptoms.
Experts recommend starting with 1–6 mg of CBD for every 10 pounds of body weight. If you’ve never taken CBD before, it’s best to start at the lowest point and slowly work your way up to the effective dosage.
Depending on the route of administration, it may take anywhere from 5 to 90 minutes for the effects to take hold.
Summarizing the Potential Effects of CBD Oil on Blood Pressure
Statistics are merciless for modern society when it comes to hypertension. The fact that we’re always rushing from A to B, spend the majority of our time sitting in one place, and consume too much processed food results in more people developing hypertension each year.
Aside from introducing obvious changes to your lifestyles, such as eating nutritious food, exercising a lot, and abstaining from alcohol and cigarettes, you may incorporate CBD oil into your regime for a significant improvement in your quality of life.
The latest research indicates that CBD is capable of lowering blood pressure on a few different levels, although more studies are needed to make conclusive claims in this subject. If you’re considering taking CBD oil for high blood pressure, make sure to talk about it with your doctor to determine if CBD products are right for you.

CBD Oil for High Blood Pressure (Hypertension) – June 2022
A sublingual application of CBD oil tincture may be the best way to take CBD for high blood pressure as it gets absorbed by the body fast, and the effects are felt for an extended period.
Why People Are Taking CBD for High Blood Pressure
According to the Centers for Disease Control and Prevention (CDC), high blood pressure can harden and narrow the arteries, which decreases the flow of blood and oxygen to the heart, leading to heart disease (5 ) .
In a 2015 study conducted by researchers from the University of Nottingham Royal Derby Hospital in the UK, CBD was shown to be a potent vascular relaxant to human gut arteries, suggesting its potential benefits to dilate blood vessels and increase blood flow (6 ) .
How CBD Oil Works to Help with High Blood Pressure
CBD has been shown to possess potential benefits that may help lower blood pressure by addressing health issues that cause blood pressure to rise.
CBD’s Anti-Anxiety Effects
Some factors linked to high blood pressure are anxiety and lack of sleep.
In a 2019 study published in The Permanente Journal , sleep and anxiety scores were measured in human subjects, and the findings showed that CBD could hold benefits for anxiety-related disorders (7 ) .
In another study , which was published in the Journal of Alternative and Complementary Medicine in 2019, CBD was shown to help in the treatment of post-traumatic stress disorder (PTSD) (8 ) .
The relaxation response can reduce blood pressure in people with hypertension, as indicated in the results of a study published in the Journal of Alternative and Complementary Medicine in 2018 (9 ) .
CBD as a Vasodilator
As a natural vasodilator, CBD may help improve positive cardiovascular health by widening the blood vessels to allow smooth blood flow.
CBD’s role as a vasodilator was highlighted in a double-blind, placebo-controlled, and randomized crossover study conducted by researchers from the Royal Derby Hospital Centre and Oxford Centre for Diabetes, Endocrinology & Metabolism, Churchill Hospital in the UK in 2017 (10 ) .
In the said study , researchers explored the connection between CBD and a reduction in blood pressure, and they found that a single dose of CBD oil significantly lowered blood pressure in a small study of healthy human volunteers, both under stress and at rest.
However, the authors also noted that “there are no dedicated studies in humans to date, to our knowledge, looking at the effect of CBD on either resting cardiovascular measurement or on the responses to stress, with continuous monitoring of cardiovascular parameters.”
CBD’s Anti-Inflammatory Effects
Studies conducted by researchers from the University of South Carolina School of Medicine in 2009 also reveal that CBD possesses anti-inflammatory properties. Since inflammation can cause high blood pressure or vice versa, eliminating inflammation may help alleviate high blood pressure (11 ) .
However, inflammation may be a result of other diseases as well. Thus, leading a healthy lifestyle while using CBD oil is advised.
CBD vs. Cortisol Secretion
Cortisol, the “stress hormone,” is released by the body under stress. An elevated cortisol level may cause a physical stress response in the body that could raise blood pressure.
Results from a 1993 study published in the Brazilian Journal of Medical and Biological Research suggested that CBD interferes with cortisol secretion (12 ) . Thus, if high blood pressure is due to elevated stress levels, CBD oil may theoretically be beneficial.
CBD and The Dynamics of Blood Flow
In a systematic review and meta-analysis published in the Frontiers in Pharmacology Journal in 2017, the authors examined the hemodynamic (blood flow) effects of CBD (13 ) .
The authors of the said study concluded that CBD might be used as a potential remedy for cardiovascular disorders, such as hypertension and stroke.
However, they found no evidence that CBD provides similar results under non-stressful conditions.
Much of these data were from mice, and results from human studies on the effects of CBD on hemodynamics is still limited.
CBD Interacts with Neurotransmitters
Results of a 2017 study published in the Cannabis and Cannabinoid Research Journal show how a neurotransmitter, such as anandamide, plays a critical role in the functioning of the heart (14 ) .
Data from the study has shown that CBD oil regulates the reuptake of essential heart neurotransmitters that control the cardiovascular system.
CBD’s Neuroprotective Effects
A study published in the British Journal of Clinical Pharmacology in 2013 has shown how CBD allows blood flow in the vessels to maintain healthy blood pressur e in animal models (15 ) .
The review has also presented evidence of the positive effects of CBD in the cardiovascular system.
Data from the said study illustrate that CBD potentially provides neuroprotective effects, which may help protect the brain against stroke.
The findings also suggest that CBD can induce a healthy heart rhythm after an ischemic attack, which is caused by a build-up or blockage in the arteries. Thus, CBD was shown to potentially improve heart performance immediately after a heart attack in non-human models.
Although the results demonstrate that the cardiovascular system is a valid therapeutic target for CBD, the target sites of action for CBD remain to be established for most of the responses.
As more and more studies and clinical trials are conducted in human subjects, CBD oil’s efficacy in treating high blood pressure would become more explicit.
The Pros and Cons of CBD Oil for High Blood Pressure
- CBD “is generally well tolerated with a good safety profile,” as the World Health Organization (WHO) states in a critical review (16 ) .
- CBD’s feasibility as a potential remedy to hypertension-related symptoms has been shown in the numerous studies stated above.
- Studies are too limited to determine whether or not CBD is an effective treatment for conditions other than the ones approved by the U.S. Food and Drug Administration (FDA).
- As with the use of any natural chemical compound, there are risks involved in using CBD. According to the Mayo Clinic, possible side effects include drowsiness, dry mouth, diarrhea, fatigue, and reduced appetite (17 ) .
- Most of the results from blood pressure-related studies done on CBD have been gathered through tests that involve healthy volunteers, very low population sizes, or animals, like that of a study done on rats (18 ) .
- CBD has been shown to alter how the body metabolizes certain medications, as a 2017 research reveals (19 ) . With results published in the Cannabis and Cannabinoid Research Journal , the research suggests that the combination of CBD with other high blood pressure medications has the potential to alter the blood concentrations of either substance.
Results of a study published in the Medicines Journal indicated that the CYP450 family of enzymes is responsible for metabolizing several phytocannabinoids (cannabinoids that exist naturally in the cannabis plant), including CBD (20 ) .
- The lack of regulation makes it difficult to determine whether the CBD gummies, tinctures, patches, balms, and gelcaps contain what the product label claims.
A 2017 review published in the Journal of the American Medical Association revealed labeling inaccuracies among CBD products. Some products had less CBD than stated, while others had more (21 ) .
Experts recommend speaking with a physician before adding CBD onto the medications that are currently taken. The doctor may want to reduce the dosage strength of the blood pressure prescription before incorporating CBD oil into the daily regimen of an individual.
How CBD Oil Compares to Alternative Treatments for High Blood Pressure
Although the prescription medications currently available for hypertension are effective, they bring about side effects, which can make the treatment an unpleasant experience.
Cannabidiol (CBD), on the other hand, is a natural alternative that has shown to have little side effects, and the side effects of CBD are less common than the effects associated with most pharmaceutical medications used to treat high blood pressure.
How To Choose The Right CBD for High Blood Pressure
The best CBD oil product to use for high blood pressure is CBD tincture. By taking a sublingual dosage, the optimum level of CBD gets absorbed into the system, which means CBD works the fastest, and the effects are probably felt the longest.
However, regardless of the form of CBD product one chooses, he or she must employ careful consideration in choosing the best CBD oil for high blood pressure that is right for him or her.
- Research on the exact legal stipulations applicable to CBD in the area where it would be purchased and used.
- Purchase only from legitimate and reliable big brands. The majority of companies that manufacture the best CBD oil products grow their hemp from their farm, or they purchase from licensed hemp producers.
- When buying from an online store, do some research on product reviews first. When buying from a physical store or dispensary, check whether the store is authorized by the government to sell CBD.
- One important thing to look for in CBD products is certification codes. Several certification authorities approve certain products only after some thorough screening tests.
- Compare company claims about their products’ potency with that of the third-party lab reports.
- Consulting with a trusted medical professional who is experienced in CBD use is ideal before purchasing any CBD product .
CBD Dosage For High Blood Pressure
In a 2019 review, Mayo Clinic suggests CBD dosages based on publications, scientific research, traditional use, and expert opinion (22 ) .
The doses and duration of treatment depend primarily on the illness. However, there is no specific dose recommended for high blood pressure.
Results of a 2017 study published in the Cannabis and Cannabinoid Research Journal provided evidence that a dosage of up to 1,500 mg of CBD a day is well-tolerated by humans (23 ) .
The authors of the study also found that at lower doses, CBD showed physiological effects that could potentially help promote and maintain health, including antioxidative, anti-inflammatory, and neuroprotection effects.
Following the dosing instructions on the CBD product of choice and starting with a low dose are the best course of action for those who would like to try CBD. Taking high doses at the beginning may bring about adverse reactions in the user.
As with any medication, the dose would depend on the metabolism, genetics, size, and body weight of a person.
How to Take CBD Oil for High Blood Pressure
There are various ways to consume CBD oil, and the delivery format would most likely depend on personal preferences and lifestyle.
CBD Oil Capsules and Edibles
CBD oil capsules and edibles, such as brownies, gummies, and lozenges, are a convenient and straightforward way to take CBD oil, especially for beginners.
This format is easy to work into a routine, and the dose is consistent. Depending on the metabolism of an individual, the effects can last between 6 and 12 hours. Thus, one dose is probably all that is needed during the day.
However, consuming CBD oil can delay its effects as it has to pass through the digestive system before it gets absorbed into the bloodstream. Given that the effects of the CBD oil could take at least 20 minutes to an hour to appear, CBD oil capsules and edibles do not provide immediate relief.
CBD Oil Tinctures or Drops
CBD oil tinctures or drops are a practical option for those who seek faster results and maximum dosage control.
Tinctures and drops are administered under the tongue, through which the CBD oil is absorbed directly into the bloodstream.
Place the desired quantity of drops under the tongue using a dropper, and then let the CBD oil stay in place for at least 60 seconds. Once 60 seconds have passed, swallow the CBD oil.
Sublingual application allows for results to be experienced within 30 to 60 minutes after its use, and the effects can be felt for 4 to 6 hours.
Since tinctures and drops are convenient and easy to store and travel with, they can be effortlessly administered when needed.
However, one significant drawback to CBD oil tinctures and drops is the taste, as not everyone appreciates the natural, earthy, and sometimes bitter flavor of hemp.
Although some products come in various flavors to compensate for the unpleasant taste, the addition of sugar and chemicals may be something that one wants to avoid.
CBD Oil Vapes
CBD oil vapes are one of the accelerated ways to get CBD into the body since it enters the bloodstream through the lungs, without going through the digestive system.
When vaping CBD oil, effects can be felt in minutes. However, the effects last only for 30 minutes to an hour or two.
Also, with vaping, it is difficult to determine precisely how much CBD is in each draw. Although labels for CBD oil vape products usually indicate the amount per inhale, the amount may vary in individuals. Thus, getting the dose right requires a bit of experimentation at first.
Understanding High Blood Pressure
Blood pressure is influenced by how much blood the heart pumps, how hard it pumps, and the resistance to blood flow in the arteries.
According to Mayo Clinic, the higher the amount of blood the heart pumps and the narrower the arteries, the higher the blood pressure (24 ) .
The narrowing and blocking of blood vessels that is caused by high blood pressure, or hypertension, affects heart health by increasing the risk of developing heart failure.
What A Blood Pressure Reading Means
When the doctor measures blood pressure, the reading is given in two numbers. The first number, referred to as systolic blood pressure, is the pressure caused by the heart contracting and releasing blood. The second number, called diastolic blood pressure, is the pressure when the heart relaxes and fills with blood.
The blood pressure reading is given as the systolic blood pressure number over the diastolic blood pressure number, such as 135/70.
A normal blood pressure reading for adults is 120/80, according to the American Heart Association (AHA) (25 ) .
Are There High Blood Pressure Symptoms?
The American Heart Association (AHA) calls high blood pressure a “silent killer.” An individual can have high blood pressure for years without any indications (26 ) .
Most people with high blood pressure do not exhibit symptoms, even though blood pressure readings rise to critically-high levels.
Meanwhile, AHA says, some people with high blood pressure may experience shortness of breath, headaches, or nosebleeds. However, these symptoms are not specific and do not occur until high blood pressure has reached a life-threatening stage.
Still, even in the absence of symptoms, damage to the heart and blood vessels continues and can be detected, AHA says .
The agency warns that undetected or unregulated high blood pressure intensifies the risk of severe health problems, including strokes and heart attacks (27 ) .
High blood pressure typically develops over several years, and it eventually affects almost everyone (28 ) .
The National Institute on Aging (NIA) states that high blood pressure is a critical health issue that is typical among older people (29 ) .
Fortunately, it is not difficult to detect high blood pressure. One can work with a doctor to control the condition once diagnosed.
To learn more about the studies on blood pressure, go to ClinicalTrials.gov or PubMed.gov (30 ) .
Traditional Medications for High Blood Pressure
- Diuretics, like Diuril and Lozol, increase urination which reduces sodium and fluid in the body. Because diuretics lower blood volume, they help lower blood pressure. However, one side effect of diuretics can be a loss of potassium, which is needed for proper muscular movement.
- Angiotensin II receptor blockers (ARBs) like Diovan, which, as vasodilators, dilate blood vessels. Their potential side effects include skin rashes, swelling mouth, joint and back pain, flu-like symptoms, nausea, headaches, and diarrhea.
- Metoprolol beta-blockers, like Toprol-XL and Lopressor, slow the heart rate. However, they can cause diarrhea, constipation, vomiting, fatigue, anxiety, depression, insomnia, shortness of breath, and decreased libido.
- Angiotensin-converting enzyme (ACE) inhibitors like Vasoctec and Benazepril prevent the contraction of blood vessels. Some adverse side effects may include skin rash, swelling mouth, dry cough, headaches, dizziness, and diarrhea.
According to an article published in MedlinePlus by the U.S. National Library of Medicine, high blood pressure medicines may cause some common side effects, such as diarrhea or constipation, dizziness, erection problems, fatigue, nausea or vomiting, skin rash, and weight loss or gain without trying (32 ) .
Sometimes, a person may need to take more than one type of drug to manage blood pressure.
Although a single drug would often be used initially, two drugs could be started for stage 2 high blood pressure.
The AHA describes stage 2 hypertension as the stage when blood pressure consistently ranges at 140/90 mm Hg or higher (33 ) .
People taking medications for hypertension are also warned that mixing beta-blockers and angiotensin II receptor antagonists must only be done at the recommendation of a physician since the combination can lead to acute renal failure, as a 2013 study published in the Hypertension Research Journal suggests (34 ) .
Lifestyle Changes to Help Prevent High Blood Pressure
- Eating a healthy diet that is low in fat, cholesterol, and salt to prevent further plaque build-up in the arteries.
- Exercising regularly to strengthen your heart. This activity could be something as simple as taking a 30-minute walk each day.
- Engaging in activities that help manage stress, such as meditation, journaling, making art, and seeing a therapist.
What to Know About CBD Oil
CBD oil contains CBD , or cannabidiol , as its primary active ingredient. Cannabidiol is associated with the previously mentioned benefits, including controlling blood pressure.
Comparing CBD and THC
CBD comes from cannabis and is naturally found in hemp plants. CBD is one of more than 100 cannabinoids that occur naturally within the plant. This compound is also commonly used to produce CBD hemp oil supplements.
Hemp seed oil is produced by extracting the oil from the seeds of the hemp plant itself. This oil is abundant in nutrients, such as omega-3 and omega-6 fatty acids, making it ideal for digestion. Although some people refer to “hemp extract” as hemp oil, the term “hemp oil” is synonymous with the term “hemp seed oil.”
Chemical compounds in cannabis, called cannabinoids, have shown various potential benefits by activating the body’s endocannabinoid system (ECS), which is involved in regulating a variety of functions including sleep, appetite, pain and immune system response (36 ) .
The body produces endocannabinoids, which are neurotransmitters that bind to cannabinoid receptors in the nervous system.
The medicinal efficacy of cannabis can be optimized by incorporating the various cannabinoids, flavonoids, and terpenes that are intrinsic components of cannabis plants.
CBD is non-psychoactive, contrasting with THC (tetrahydrocannabinol), another primary cannabinoid. THC is the most significant factor contributing to the high associated with using cannabis.
Consuming CBD without any THC does not produce those effects, which means that nearly everyone should be able to function as they usually do when taking CBD.
The lack of high allows users to continue with work, school, and other commitments without a decrease in performance. It also makes CBD oil safe to take , even for those who must pass regular or random drug tests.
CBD oil must not contain any THC for CBD to be non-psychoactive. Products containing CBD isolates do not have THC, while full-spectrum CBD products do.
Any product that one buys should also state the percentage of THC, information which one can also get from its certificate of analysis.
Other Health Benefits of CBD Oil
Here are some of the more critical benefits associated with cannabidiol .
CBD can help treat some of the worst types of seizure disorders that exist, including Lennox-Gastaut syndrome and Dravet syndrome, both of which affect children and do not typically respond to traditional medications for treating seizures (37 ) .
Even the U.S. Food and Drug Administration (FDA) recognizes the ability of CBD to treat seizure disorders (38 ) . The first cannabis-derived medication it approved is Epidiolex, which treats these conditions. That medication contains CBD.
Treating Anxiety Disorders and Depression
Those who suffer from anxiety may experience relief with CBD. Results from a 2019 study published in the Brazilian Journal of Psychiatry showed CBD’s anxiolytic effect on public speaking, and there is plenty of anecdotal evidence (39 ) .
In another study , which was published in the Journal of the American College of Cardiology , CBD was shown to attenuate oxidative stress, as well as cardiac dysfunction, fibrosis, and cell death in a mouse model (40 ) .
One of the most popular uses of CBD oil is its ability to reduce chronic pain . Animal studies, like the study published in the European Journal of Pain in 2016, show that topically applied CBD may theoretically help provide pain relief and reduce inflammation from arthritis (41 ) .
In another study published in the Journal of Experimental Medicine , CBD was shown to reduce neuropathic pain (42 ) . This finding is crucial as it is one of the hardest types of pain to treat.
Some countries approve oral sprays like Sativex, which contains both CBD and THC (43 ) . This spray effectively treats the pain associated with multiple sclerosis (MS), a potentially disabling disease of the brain and spinal cord (central nervous system).
However, as Sativex and certain medications may trigger a drug interaction, experts advise consulting with a doctor first about all the prescription, over-the-counter (non-prescription), and herbal medications that are being taken before starting to use Sativex oral spray.
Protecting the Brain
CBD research , conducted on animal models and humans and published in the Surgical Neurology International in 2018, has shown numerous therapeutic properties for brain function and protection, both by its effect on the endocannabinoid system directly and by influencing endogenous cannabinoids (44 ) .
Researchers in a study published in the Journal of Psychopharmacology noted a possible effect of CBD in improving the quality of life in patients with Parkinson’s disease without adverse outcomes (45 ) .
Studies analyzed in a 2017 review conducted by experts from the Western Sydney University in Australia also provided proof of principle for the therapeutic benefits that CBD and possibly CBD-THC combinations may provide (46 ) .
Data suggest that these combinations may help with the therapy of Alzheimer’s disease (named after Dr. Alois Alzheimer, who noted the symptoms in 1906).
May Help Fight Cancer
A 2010 study published by the American Association for Cancer Research showed a CBD-induced cell death of breast cancer cells, suggesting that the use of CBD oil may also suppress tumor growth (47 ) .
Research on cannabinoids published in the Future Medicinal Chemistry demonstrates that cannabinoids may also prove beneficial in certain types of cancers that are activated by chronic inflammation (48 ) .
In such instances, cannabinoids, as anti-inflammatory agents, can either directly prevent tumor growth or suppress inflammation .
Meanwhile, in-depth research on CBD yields mixed results.
In a recent study published in the Bosnian Journal of Basic Medical Sciences , researchers recognized the antitumor effects of cannabinoids in various cancer types (49 ) .
However, these antitumor effects of cannabinoids have to prevail over their known immunosuppressive effects, which can potentially promote the production or formation of tumors.
Recent studies are still limited when it comes to CBD and cancer prevention. Longitudinal studies of humans using specific CBD products, controlling for frequency of use and dosing are needed.
Overcoming Substance Abuse
There is some evidence that using CBD may help those with addiction overcome their substance abuse.
Published in the Journal of Substance Abuse Treatment , results from a 2015 study conducted on animal models showed CBD reduced heroin-seeking behavior and reduced morphine dependence (50 ) .
The Legality of CBD Oil
The Cannabis sativa plant produces both hemp and marijuana. The difference between the two plants is the percentage of THC that they contain.
A cannabis plant that has 0.3 percent or less of THC content classifies as hemp, while a cannabis plant containing over 0.3 percent of THC is considered marijuana.
In the United States, cannabis-related laws are continually changing. Since marijuana and THC are on the list of controlled substances, they are currently prohibited under federal law (51 ) .
Meanwhile, confusion arises due to regulations that vary depending on whether the CBD is hemp-derived or extracted from marijuana. The former is legal at the federal level, while the latter is not.
Many states and Washington, D.C. have passed cannabis-related laws, making medical marijuana with high levels of THC legal. Still, marijuana may require a prescription from a licensed physician (52 ) .
Also, several states have made recreational use of marijuana and THC legal. One should be able to buy CBD in states where marijuana is legal for recreational or medical purposes.
NORML has information regarding state laws and penalties. (53 ) .
Individuals who possess cannabis-related products in a state where they are illegal or do not have a medical prescription in states where the products are legal for medical treatment could face legal penalties.
For a complete list of legal medical marijuana states and D.C., including the corresponding laws, fees, and possession limits, visit ProCon.org (54 ) .
According to the Centers for Disease Control and Prevention (CDC), about 75 million American adults, or 1 in 3 adults, have high blood pressure (55 ) . People with high blood pressure have a greater risk of heart disease and stroke, the leading causes of death in the United States.
CBD oil has shown to be a natural remedy to issues that could be linked to high blood pressure, such as stress and p a in (56) .
Meanwhile, using medications as prescribed and making lifestyle changes can enhance the quality of life and reduce the risk of hypertension, says the American Heart Association (AHA) (57 ) .
Still, before experimenting with different CBD products and dosages, speak to a doctor about a CBD treatment or using CBD oil for treating high blood pressure.
For anyone still looking for more information on CBD as a medical supplement, speaking with a cannabis doctor who specializes in the subject is the best course of action.
