Valerian root is a herbal remedy that has been used for centuries to promote relaxation and improve sleep quality. Derived from the Valeriana officinalis plant, this root is often found in supplement form, including capsules, tablets, and teas. It is known for its distinct earthy smell, which some people find quite strong. Valerian root is believed to work by increasing levels of a neurotransmitter called gamma-aminobutyric acid, or GABA, in the brain. This helps to calm the nervous system and reduce anxiety. Many people turn to valerian root as a natural alternative to prescription sleep aids, as it is generally considered to have fewer side effects. However, it is always recommended to consult with a healthcare provider before starting any new supplement, especially for those who are pregnant, nursing, or taking other medications.
