Wood Betony

A European nervine (Stachys officinalis) traditionally used for tension headaches and nervous unease. Modern research covers its chemistry but not its clinical effects — there are no human trials.

Evidence last reviewed: August 2026

What the science says

  • Tension headache and nervous tension Limited evidence

    A review of the genus Stachys documents wood betony's long traditional use for headache, anxiety and nervous complaints, but identifies no randomised or controlled clinical trials for these indications. The claim rests on herbal tradition alone.

  • Antioxidant and anti-inflammatory activity Limited evidence

    Phytochemical and biological reviews of Stachys species describe phenylethanoid glycosides and flavonoids with antioxidant and anti-inflammatory activity in laboratory assays. These are in vitro findings without a demonstrated clinical consequence.

  • Sedative or sleep effect Limited evidence

    No study has measured sleep latency, sleep quality or anxiety scales in people taking wood betony. Its use as a calming herb is traditional rather than tested.

Dosage & safety

Studied doseNo studied dose. Traditional use is 1–2 g of dried aerial parts as an infusion up to three times daily, or 2–6 mL of tincture; capsule labels typically list 300–500 mg.
SafetyLong traditional use with few reported problems, but no formal human safety data. It has traditional uterine-stimulant use and should be avoided in pregnancy; avoid also while breastfeeding. Large amounts may irritate the stomach. Do not confuse it with Pedicularis species, which are also sold as 'betony'; check the botanical name on the label.
