Medicinal claims

People take valerian mostly as a sedative and sleep aid, especially in parts of Europe. Studies have suggested that valerian improves sleep quality and shortens the time needed to fall asleep. In menopausal women with difficulty sleeping, valerian may improve sleep quality.

Some people take valerian for headaches, depression, irregular heartbeat, and trembling, although evidence is insufficient. It is usually used for short periods of time (2 to 6 weeks). There is not enough scientific evidence to determine whether valerian is effective for these conditions. There is now interest in studying valerian to treat obsessive-compulsive disorder.

Possible side effects

Studies suggest that it is generally safe to give valerian at the usual doses. People who are driving or doing other activities requiring alertness should not take it.

Valerian is not recommended for women who are pregnant or breastfeeding.

Possible drug interactions

Valerian may prolong the effect of other sedatives (such as barbiturates) when it is taken with them.

Computerized Tomography (CT)
In computerized tomography (CT), x-ray images of the body are taken from multiple angles and converted by a computer into images resembling 2- and 3-dimensional slices (cross-sections). People having a CT scan are asked to remove all jewelry and metal items such as zippers and belt buckles located near the body part being scanned. Why are patients asked to remove metal before having a CT scan?
