Dr. Joseph Mercola was recently featured in a Fox News health article that takes a closer look at valerian, a well-known herbal remedy often used to support sleep.
The report explores the popular claim that valerian acts as “nature’s Valium,” while also examining what scientific research and medical experts actually say about that comparison. While the herb has been used for centuries, the question remains whether its calming reputation is fully supported by modern studies.
In the article, Mercola explains that valerian root contains compounds that may influence brain chemicals linked to relaxation and sleep. Some studies have suggested it may help certain people fall asleep faster or experience slight improvements in sleep quality. However, the research has produced mixed results, raising questions about how powerful its effects truly are.
Mercola also highlights an important point that many people overlook. Long-term safety data on valerian is still limited, and supplement quality can vary widely depending on the product. Because of these uncertainties, he emphasizes the importance of starting with foundational habits that naturally support sleep, such as consistent exposure to natural daylight during the day and maintaining a dark, quiet environment at night.
The Fox News article dives deeper into the science behind valerian and why experts say lifestyle factors still play the biggest role in healthy sleep patterns. If you’re curious about how this popular herb compares to the claims surrounding it, the full article offers a closer look at the evidence and expert insights.
