Research Summary

Blue vervain has a tradition as a calming nervine and digestive. Clinical evidence is insufficient; preclinical work shows mild relaxing and anti-inflammatory activity, but it is not a treatment for anxiety, insomnia, depression, or any disease.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
