Oxford, United Kingdom — Oral CBD administration is associated with reduced blood pressure in healthy volunteers, according to clinical trial data published online in the Journal of Clinical Investigation.
Investigators from the University of Nottingham assessed the effects of a single oral dose of 600 mg of CBD extract versus placebo in nine male subjects.
Cannabidiol administration reduced resting systolic blood pressure and stroke volume (the amount of blood pumped by the left ventricle of the heart in one contraction). Compared to placebo, CBD intake was associated with reduced BP levels following exercise and in response to stress. Increased heart rate was observed following CBD administration, but no “adverse events” were reported by participants either during or following the study sessions.
Authors concluded: “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. … Further research is also required to establish whether CBD has any role in the treatment of cardiovascular disorders such as a hypertension.”
