Overview

Valerian (Valeriana officinalis) is a perennial flowering plant native to Europe and Asia. The root of the plant has been used for centuries as a traditional herbal remedy for sleep disturbances and anxiety. Historical texts indicate its use dating back to ancient Greece and Rome. Today, valerian root is widely available as a dietary supplement in various forms, including capsules, tablets, teas, and tinctures, primarily marketed for its potential to support sleep. The plant contains numerous bioactive compounds, including valerenic acid, iridoids (valepotriates), and flavonoids. Researchers believe that these compounds, working synergistically, contribute to valerian's proposed effects. While its use as a sleep aid is common, the scientific understanding of its efficacy and precise mechanisms of action continues to be an area of active research. Consumers often seek valerian root as a natural alternative to pharmaceutical sleep aids.
