The valerian plant is a perennial herb native to Europe and parts of Asia. It typically grows between 2 to 4 feet tall and features clusters of small, fragrant white or pink flowers. The plant is known for its distinctive, feathery leaves and has a strong, earthy aroma. Valerian is most commonly recognized for its roots, which have been used for centuries in traditional medicine. The root is often made into teas, tinctures, or capsules and is primarily used to promote relaxation and improve sleep quality. Its calming effects are attributed to compounds like valerenic acid.
