Will it improve sleep?
A 2024 umbrella review of eight reviews found signals of improved self-reported sleep quality, but no convincing benefit on quantitative or objective measures. Studies differed considerably and often had methodological weaknesses. The authors did not find sufficient support for treating insomnia. 1
Some people reported better sleep; objective findings did not consistently confirm it. 1
What about nervous tension?
EMA recognizes a specific ethanolic dry extract for mild nervous tension and sleep disorders. Other preparations have traditional-use indications, based on long-standing use rather than clinical proof. This assessment concerns herbal medicines, not every supplement. 2
