Dr. Joseph Mercola was recently featured in a Fox News health article exploring valerian, a widely used herbal remedy often promoted as a natural sleep aid.
The report takes a closer look at the popular claim that valerian acts as “nature’s Valium,” while comparing that reputation with what current scientific research actually shows. In the article, Mercola explains that compounds found in valerian root may influence brain chemicals involved in relaxation and sleep. While some studies suggest the herb may slightly improve sleep quality or help people fall asleep faster, research results have been mixed.
Mercola also points out that long-term safety data on valerian remains limited and that supplement quality can vary widely. Because of these uncertainties, he stresses the importance of focusing first on simple lifestyle habits that support healthy sleep, such as getting natural daylight during the day and keeping a dark, consistent sleep environment at night.
The Fox News piece explores the science behind valerian in greater detail and examines what experts say about its true role in sleep support. If you’re curious how the research compares to the hype, the full article takes a deeper look.
