CBD oil is a natural way to aid in pain management, sleep, anxiety and recovery. However, studies have been conducted that suggest CBD can help lower blood pressure (BP), specifically high blood pressure related to stress.
CBD’s Link to Blood Pressure (Hypertension)
When your blood is pumped through blood vessels there is a certain amount of force that occurs. This is your blood pressure. When your blood pressure is high there is more force that is put on your blood vessels which may damage your blood vessels, veins, and arteries. High blood pressure or hypertension can lead to many problems including heart disease, heart attack, stroke, heart failure, aneurysm, and even dementia.
Ways to lower your blood pressure naturally include limiting salt intake, decreasing alcohol or tobacco use, eating more fruits and vegetables, regular exercise, and reducing stress. If that doesn’t work doctors will often prescribe ACE-inhibitors to lower BP but those medications often come with side effects including dizziness, swelling of ankles, headaches, and constipation.
A new study suggested that CBD can lower blood pressure in a natural way without harmful or annoying side effects. As always consult your physician before taking CBD or changing any medications.
Single Dose of CBD can help lower blood pressure
A recent study examined the relationship between high blood pressure and CBD. Nine healthy men were given either 600mg of CBD or a placebo and then different stress tests were conducted to examine blood pressure throughout the study.
All stress tests elevated the subjects heart rate and blood pressure. Only CBD patients reacted positively to the stress tests after they were conducted (in the recovery stage). CBD patients showed a natural decrease in blood pressure and their blood pressure stayed lower than the placebo subjects.
“Based on preclinical evidence, the aim of this study was to test the hypothesis that CBD would reduce the cardiovascular response to stress in healthy volunteers. We found that resting blood pressure was lower after subjects had taken CBD and that CBD blunted the blood pressure response to stress, particularly in the pre and post-stress periods.”
This sample study sheds light on how CBD can help reduce stress in subjects after just one dose. This experiment was only conducted on nine healthy individuals; more studies need to be completed before claiming that CBD can help with cardiovascular conditions. However, the findings also correlated with another study that showed how CBD affects cortisol levels.
Effect of CBD and Cortisol (the stress hormone)
Cortisol is the body’s stress hormone. Cortisol is also the body’s alarm system and is responsible for the “fight or flight” response by working with your brain to control mood, motivation and fear. When your body is on high alert and has raised cortisol levels it can shut down other functions of the body in order to keep the body ready to “fight or flee.” Functions of the body that may be suppressed can include the reproductive system, immune system or growth processors.
If your body is on constant high alert due to high levels of cortisol it can cause anxiety, depression, digestive problems, headaches, heart disease, weight gain and memory loss. Too much cortisol in the body for an extended period of time is harmful to the way the body operates.
A double-blind study was conducted on 11 normal subjects showing the effects of CBD on plasma prolactin, growth hormone, and cortisol. The subjects were given 300mg of CBD while the others were given a placebo. The results showed that CBD significantly decreased the amount of cortisol produced. According to the study, “CBD was also found to have a sedative effect as determined by the self-evaluation scales. The present results suggest that CBD interferes with cortisol secretion.”
How much CBD to take?
Since CBD is not yet FDA approved, there is no official recommendation on how much to take. Our suggestion would be to first consult your medical professional and start with a low dose of CBD and scale up or down as needed. Our Vitality CBD products are great for general wellness and a good starting product. Our Recovery CBD product has the highest concentration of CBD with 3000mg.
