Valerian

Valerian is a herbal supplement derived from the roots of the Valeriana officinalis plant, commonly used to promote relaxation and improve sleep quality. It is believed to work by increasing levels of gamma-aminobutyric acid (GABA) in the brain, a neurotransmitter that helps calm neural activity and reduce anxiety. While some people find it helpful for insomnia and stress, scientific evidence varies, and effects can differ among individuals. Valerian is generally considered safe when used appropriately, but it may cause side effects like dizziness or gastrointestinal discomfort. Always consult a healthcare provider before starting new supplements, especially if you are on medications or have health conditions.
