Capitate Valerian (Valeriana capitata), like its more commonly known relative Valeriana officinalis, has a history of traditional use among indigenous peoples of North America, particularly in Alaska and northwestern Canada. Traditionally, the root of Capitate Valerian was used for its calming effects, including as a mild sedative, sleep aid, and to alleviate anxiety or nervous tension. These uses parallel the historical application of Valeriana officinalis in Europe, which has been more extensively studied and is known to affect the GABAergic system by enhancing gamma-aminobutyric acid (GABA) activity in the brain, leading to sedative and anxiolytic effects.

However, direct scientific evidence specific to Capitate Valerian’s effects on the GABA system is lacking. Most research has focused on Valeriana officinalis, which contains valerenic acid and related compounds that modulate GABA receptors. There is currently insufficient phytochemical or clinical research on Capitate Valerian to confirm that it contains the same active compounds or works through the same mechanisms. Therefore, while its use to support GABA-related body systems (such as for anxiety or sleep) is justified by tradition, it is not strongly supported by modern scientific validation. Further research is needed to confirm its efficacy and pharmacological properties.
