A new study published in JCI Insight suggests CBD reduces systolic blood pressure, which could have beneficial implications for cardiovascular disorders. Researchers from the University of Nottingham looked at the cardiovascular effects of a single oral dose of 600mg CBD when compared to placebo in nine healthy male adults averaging around 24 years old. The investigators monitored cardiovascular parameters like blood pressure, heart rate, stroke volume, and skin blood blow, while subjects were at rest and when subjects under went stress tests for two hours.
Researchers concluded CBD reduced systolic blood pressure by an average of 6 mmHg at rest, 5 mmHg before and after stress, and 6 mmHg in response to cold stress. CBD also reduced stroke volume and increased heart rate by about 7 beats per minute, but there was no observed decline in cardiac output. The study determined, “Our data show that a single dose of CBD reduces resting blood pressure and the blood pressure response to stress, particularly cold stress, and especially in the post-test periods. This may reflect the anxiolytic and analgesic effects of CBD, as well as any potential direct cardiovascular effects."
