Does valerian work against insomnia?

Valerian root, an herb often used as a natural sleep aid, has been used for centuries to treat insomnia and other sleep disorders. However, valerian's effectiveness in promoting sleep is mixed and still being researched.

Some research suggests that valerian root may shorten the time it takes to fall asleep and improve sleep quality. It seems especially helpful for people who have trouble falling asleep. Valerian is also used to reduce anxiety, which can indirectly improve sleep for people who keep awake due to anxiety.

Not all studies agree on the effectiveness of valerian. Some studies show no significant difference in sleep quality or sleep duration compared to a placebo. Many of the available studies have methodological limitations, such as small sample sizes or a lack of rigorous control, which can affect the reliability of the results.

Although valerian is generally considered safe, some people may experience side effects such as headaches, dizziness, stomach upset, or drowsiness the next day.

Valerian may be effective in improving sleep for some people, especially with short-term use and mild to moderate insomnia. However, the variable results and methodological limitations of the studies mean it may not work for everyone. For severe or chronic insomnia, it is advisable to consult a doctor for personalized treatment.
