Which of the following is an adverse reaction associated with Valerian?

Drowsiness is an adverse reaction associated with Valerian due to its sedative properties. Valerian is often used as an herbal remedy for anxiety and sleep disorders, and its mechanism involves increasing the levels of GABA (gamma-aminobutyric acid) in the brain, which contributes to its calming effects. Because of this sedative action, drowsiness is a common side effect, particularly when taken in higher doses or combined with other CNS depressants.

Understanding this adverse reaction is crucial for nursing practice, especially when educating patients about the potential effects of Valerian on their daily activities, such as driving or operating machinery. Awareness of the sedative effects also helps nurses monitor patients who may be using Valerian in conjunction with other medications that exert similar effects.
