How long do the effects of the herb valerian last ?

manser asked:


I’ve been using valerian to improve my quality of sleep. I used it on a Thursday night and then had a sleep study friday night. I didn’t take the valerian friday but I’m wondering if it could alter results(heartbeat,etc).

    It was probably still in your bloodstream. If, at the time, you didn’t tell the technician that you use valerian (even though you didn’t take it that night), you should mention it to your doctor when it comes time for you to discuss the results with him/her.
