Which herb contains valerenic acid and is used for insomnia and anxiety?

Valerenic acid is a hallmark constituent of Valerian root, which is traditionally used for sleep problems and anxiety. The calming effects of valerian are thought to come from valerenic acid and related compounds that modulate GABAergic activity, helping with sleep onset and reducing nervous tension. This makes Valerian the best fit for insomnia and anxiety. The other herbs listed do not contain valerenic acid and are associated with different uses—nettles are usually nutritive/anti-inflammatory, viburnum is used for cramps or broader nervine support, and vervain is a nervous system tonic without this key constituent.
