METHODS. Nine healthy male volunteers were given 600 mg of CBD or placebo in a randomized, placebo-controlled, double-blind, crossover study. Cardiovascular parameters were monitored using a finometer and laser Doppler.

The effects of placebo (closed square) and CBD (open square) on systolic blood pressure (SBP) (A), diastolic blood pressure (DBP) (B), mean arterial blood pressure (MAP) (C), heart rate (HR) (D), stroke volume (SV) (E), cardiac output (CO) (F), ejection time (EJT) (G), total peripheral resistance (TPR) (H), and forearm blood flow (I), measured continuously just before, during, and after isometric exercise test (dotted line denotes stress test period), except for forearm blood flow. Measurements for forearm blood flow were made over a 2-minute window just before, during, and after the stress test. Repeated measures 2-way ANOVA; mean ± SEM (*/ + / # P < 0.05; **/ ++ / ## P < 0.01; ***/ ### P < 0.001; ****/ #### P < 0.0001 using Bonferroni post-hoc analysis; + and # denote significant change in a parameter during the stress period seen with placebo and CBD respectively).
CBD treatment reduced resting systolic blood pressure (SBP) (mean difference –6 mmHg; 95% CI, –1 to –12, P < 0.05, Figure 1A ). Although there was no overall difference in diastolic blood pressure (DBP) and mean arterial blood pressure (MAP) between the 2 groups, post-hoc analysis showed that both DBP and MAP were lower with CBD treatment ( Figure 1, B and C , respectively; P < 0.01), particularly in the latter time points (120–160 min).
In a 2019 study, Brazilian researchers investigated the effects of several different CBD doses on anxiety levels caused by public speaking.
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.
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.
How Could CBD Lower Blood Pressure?
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.
However, a 2017 review of 25 studies found that there’s no link between CBD and reduced heart rate under non-stressful conditions.
These changes, require time and commitment to receive any benefits.
This pressure tends to go up and down throughout the day as your body reacts to environmental, physical, and emotional stimuli.
