Topical Cannabidiol Application and Skin Vascular Reactivity (cannabidiol)

Cannabidiol and Vascular Reactivity to Skin Sensory Nerve Stimulation

Cannabidiol, or CBD, is an over-the-counter "nutraceutical" that is more commonly being used by healthy adults for pain management, recovery from strenuous exercise, and general wellness. However, little research exists on the effects of CBD in otherwise healthy individuals. This study uses iontophoresis, a common technique used in physical therapy, to determine the effectiveness of topical CBD in lessening the reflex increased cutaneous vascular conductance response to stimulation of the skin.
