Hello,
A study published last year found that a 600mg dose of CBD reduced blood pressure while resting, as well as when under physical or mental stress; however, 600mg is an extremely high dose and this study involved only men with normal baseline blood pressures. Anecdotally though, many patients have reported a noticeable reduction of blood pressure while taking "normal" doses of CBD, such as 10mg three times per day. Please consult with a physician before starting any cannabis regimen.
