Valerian: An Ancient Herb Still Used Today
Valerian is a plant native to Europe and Asia that was later brought to
North America. It has been used since ancient Greek and Roman times.
In the second century, Valerian was prescribed by the physician Galen
for the treatment of insomnia. Current studies suggest that valerian may
improve insomnia, but more research is needed to confirm this effect. It
was also used to treat anxiety, chest pain, heart failure, and indigestion.
Topical valerian preparations have also been used to treat acne and skin
sores.
The roots and stems of the valerian plant are used to make supplements.
They are prepared as teas, capsules, and tablets. Mild side effects
have been reported including headache, dizziness, nausea, and or
fatigue on the morning after use. Doses ranging from 400-900mg of the
valerian extract taken 30 to 60 minutes before bedtime have been studied
for the treatment of insomnia. Long term use of valerian has not been
evaluated. However, it has been safely used in some studies for up to 6
weeks. Women who are pregnant or breastfeeding should not use valerian.
Care should be taken when using valerian due to its sedating effects.
