Valerian root works similar to Xanax (alprazolam), where it inhibits the breakdown of GABAi  A key neurotransmitter in the brain that blocks specific signals and offers a calming effect in humans. (gamma-Aminobutyric acid) in the brain. This promotes calmness and sleep. Active constituents in valerian root — valeric acid and valerian extract — exert this action. A study suggests that valeric acid and valerian extract act by binding to the GABA-A receptors (receptors that respond when GABA is released). Both the agents enhance the response to GABA and show a significant sedative action (3),(4).

Sleep plays a major role in many bodily functions (5). Hence, chronic insomnia can impact one’s overall health and well-being. Studies show that herbal medicines like valerian root may be effective in promoting sleep and preventing related disorders (6).

Armand Diaz, author and consciousness blogger, shares his experience of using valerian root as a sleeping aid and for lucid dreaming: “When I take valerian [root], it is very easy to fall back asleep if I awaken during the night. My dreams are somewhat more vivid, but also more difficult to remember, no doubt because I am inclined to go back to sleep (i).”

Another blogger talks about using valerian root for enhanced sleep despite a bothersome pain in the neck. “Taking Valerian Root at night had helped me to sleep lying down and provided relief from the loud pinched nerves that kept informing me of the issue [sic] (ii),” she claims.
