Can CBD Lower Blood Pressure? | What Does the Research Say?
Written by Jordan Caulfield & Reviewed by Paul Holmes.
CBD, short for cannabidiol, is a naturally occurring compound in the hemp plant that has garnered significant attention for its potential health benefits. As part of the cannabis plant family, CBD is non-psychoactive, meaning it does not cause the “high” associated with THC.
One of its lesser-explored potential benefits is its effect on blood pressure, making it a popular topic of interest for researchers and wellness enthusiasts.High blood pressure, or hypertension, is a silent yet prevalent global health concern that affects millions of people.
Known as a “silent killer,” it often presents no symptoms until serious complications arise, such as heart disease or stroke. Hypertension significantly impacts the cardiovascular system, leading to issues like arterial stiffness and dysfunction.In this article, we delve into the science behind CBD and its potential to support blood pressure regulation. Additionally, we explore holistic strategies of how to maintain cardiovascular health, and how supplements and natural blood pressure reducants can support your wellness journey.
Introduction to CBD and Blood Pressure
Cannabidiol (CBD) is a non-intoxicating compound found in the cannabis sativa plant that has garnered attention for its potential therapeutic benefits, including its effects on blood pressure.
Hypertension, or high blood pressure, is a significant risk factor for cardiovascular disease and related health issues. Recent studies have begun to explore the relationship between CBD and blood pressure, with some evidence suggesting that CBD may help lower blood pressure in individuals with hypertension. This emerging research offers hope for a natural approach to managing cardiovascular health.
Understanding Blood Pressure
Blood pressure is the force exerted by blood against the walls of blood vessels as it circulates throughout the body. It is measured in millimeters of mercury (mmHg) and is expressed as two numbers: systolic blood pressure (the top number) and diastolic blood pressure (the bottom number).
Systolic blood pressure measures the pressure in the arteries when the heart beats, while diastolic blood pressure measures the pressure in the arteries between beats.A normal blood pressure reading is typically around 120/80 mmHg.
Understanding these numbers is crucial for recognising and managing hypertension, a key factor in cardiovascular disorders.
Scientific Studies on CBD and Systolic Blood Pressure
Recent research highlights CBD’s potential to positively influence blood pressure, particularly under conditions of stress. A landmark study found that a single dose of CBD significantly reduced resting blood pressure and moderated the body’s blood pressure response to stress [1].
Participants in this study demonstrated a reduction in both systolic and diastolic blood pressure levels.Additionally, a randomized crossover study of men evaluated the effects of CBD on blood pressure during exercise stress, highlighting the importance of studying both acute and repeated dosing in healthy volunteers[2].
The study suggests that CBD’s (anxiety-reducing) and vasodilatory (vessel-widening) properties play a crucial role in these outcomes.By interacting with receptors in the endocannabinoid system (ECS), CBD influences the regulation of stress responses and vascular function.
This may help reduce cortisol levels, the primary hormone associated with stress, which then helps stabilise blood pressure.Other research has focused on CBD’s anti-inflammatory properties, which are important because chronic inflammation is a key driver of hypertension. By reducing oxidative stress and inflammation, CBD could provide a protective effect against the long-term risks associated with high blood pressure.
CBD’s Effects on Cardiovascular Parameters
CBD has been shown to influence various cardiovascular parameters, including arterial stiffness, blood flow, and endothelial function. Arterial stiffness, a measure of the flexibility of the arteries, is associated with an increased risk of cardiovascular disease. Research indicates that CBD may help reduce arterial stiffness in human mesenteric arteries, potentially contributing to lower blood pressure.
By improving these cardiovascular parameters, CBD could play a role in supporting overall cardiovascular health and reducing the risk of cardiovascular diseases.
Arterial Stiffness and CBD
Arterial stiffness is a significant risk factor for cardiovascular disease, and CBD may help to reduce it. A study published in 2018 found that CBD reduced arterial stiffness in human mesenteric arteries, which may help to lower blood pressure.
The study used a randomized crossover design and found that CBD significantly reduced arterial stiffness compared to a placebo. These findings are encouraging, but further research is needed to confirm the results and to understand the mechanisms by which CBD affects arterial stiffness.
This area of study holds promise for identifying new therapeutic targets for managing hypertension and improving cardiovascular health.
How CBD May Impact Blood Pressure Long-Term
While single-dose studies have demonstrated immediate benefits, consistent CBD use might offer even greater advantages for long-term blood pressure management. Long-term studies often utilize 24-hour ambulatory blood pressure monitoring (ABPM) to assess the continuous impact of CBD on blood pressure.
Factors contributing to this include:Stress Reduction: Chronic stress and anxiety can lead to prolonged blood pressure elevation. CBD’s ability to regulate mood and promote relaxation may help mitigate this effect over time.
Improved Vascular Health: By promoting vasodilation and reducing vascular tension, CBD may help prevent the narrowing of arteries, a key factor in hypertension. Studies evaluating the long-term effects of CBD on blood pressure also consider body mass index (BMI) as a crucial factor in understanding participant characteristics and health outcomes.
Anti-Inflammatory Effects: Chronic inflammation damages arterial walls, leading to conditions like atherosclerosis. CBD’s anti-inflammatory properties may protect against such damage.

Is CBD Safe to Use for High Blood Pressure?
CBD is widely regarded as safe for use, with a favourable safety profile supported by both clinical and anecdotal evidence. Researchers are also exploring CBD as a therapeutic target for managing high blood pressure, particularly due to its potential effects on the cardiovascular system.
However, like any supplement, it is not without potential side effects. More likely for individuals with pre-existing conditions or those on medications.
While free radicals play a role in immune defence and cell signalling, an excess can lead to oxidative damage.
ROS, such as superoxide and hydrogen peroxide, can initiate chain reactions that damage cell membranes, proteins, and DNA, leading to inflammation and cellular dysfunction3.
Common Side Effects of CBD
Some users may experience mild side effects, including:
- Drowsiness or fatigue
- Dry mouth
- Lightheadedness or dizziness
- Changes in appetite or weight
Individuals with primary hypertension might experience specific side effects when using CBD.
Medication Interactions to Consider
CBD may interact with medications, including medications prescribed for existing blood pressure management. Specifically, it can affect the metabolism of certain drugs by inhibiting liver enzymes like CYP3A4, potentially altering their efficacy.
If you are currently taking blood pressure medications, it is best to consult a healthcare provider before as a precaution before incorporating CBD into your daily routine. Learn more about safe CBD use here.

- Regular Exercise: Physical activity strengthens the heart and improves circulation. Aim for at least 150 minutes of moderate aerobic exercise weekly.
- Stress Management: Techniques such as mindfulness meditation, yoga, and deep breathing can lower cortisol levels and reduce blood pressure.
- Adequate Hydration: Proper hydration helps maintain blood volume and reduces strain on the heart.
- Antioxidant Support: Supplements like NAC and Resveratrol provide antioxidant protection, reducing oxidative stress on blood vessels.
How to Incorporate CBD and Lifestyle Changes for Better Blood Pressure
Combining CBD with heart-healthy lifestyle choices can amplify its benefits, including reducing blood pressure. Here’s how to integrate both effectively:
Morning Routine: Start your day with a dose of CBD oil to promote calmness and focus.
Post-Workout Recovery: Pair CBD with Digest Capsules to aid muscle recovery and optimize nutrient absorption.
Evening Relaxation: Meditation or Yoga can help unwind, promote muscle relaxation, and support restful sleep.
