What is a common adverse effect associated with valerian?

Valerian is an herbal supplement often used for its sedative properties, which makes sedation a common adverse effect. It is primarily utilized to help with sleep disorders and anxiety due to its ability to promote relaxation and drowsiness. Many individuals report feeling more relaxed or sleepy after taking valerian, which is precisely why it is recommended for those experiencing insomnia or stress.

While it's possible for valerian to cause some of the other listed effects in certain individuals, sedation is the most widely recognized and expected reaction, especially considering its intended use. In contrast, issues like cardiac arrhythmia or increased heart rate are not typical outcomes associated with valerian and are generally linked to other substances or conditions. Fatigue can be a concern as well, but it is secondary to the more prominent sedative effect that valerian is known for.
