Historical Use

Although not specifically named in Roman or Greek medical writings, Hippocrates was believed to be using valerian root as a medicinal agent for sleep problems as early as 420 BC.

Valerian root has been used in Europe, Asia, North America, and Australia; as documented in Greek, Anglo-Saxon, Medieval, and Renaissance texts. It was used to promote sleep, as a sedative, to relieve nausea, and for urinary and gastrointestinal issues.

Modern Uses

Valerian root is most commonly used to promote sleep in people with mild to moderate insomnia. In addition to promoting sleep, it has also been used to calm nerves, as a natural sedative and to help relieve premenstrual symptoms.

Mechanisms of Action

Most of the modern research on this herb centers around the traditional use of valerian root sleep preparations, as well as its use as a sedative and muscle relaxant.

Researchers have paid close attention to the effect of valerian root on the GABA neurotransmitter receptors. Although clear results have been demonstrated, the mechanism with which valerian affects these receptors is not clear, and more research is needed.
