Both ancient Greek physicians Hippocrates and Galen prescribed the medicinal herb valerian as a remedy for insomnia. A few thousand years later, it is still a popular sedative among those seeking a good night’s sleep.
There are over 200 known species of the valerian plant found in Asia, Europe, and North America. The Eurasian variety of the plant V. Officinalis is the one most often used for medicinal use.
Various sources of research and scientific study suggest 300mg to 900mg up to thirty minutes to two hours before bedtime. Other research proposes that the effect of Valerian root is more effective when taken over some time and possibly not initially on the first few evenings.
