Botanical Description
Stachys officinalis (betony, wood betony; sometimes placed in Betonica) is a rhizomatous, patch-forming herbaceous perennial in the mint family (Lamiaceae), reaching 30–60 cm in height. From the slowly creeping rhizome arises a basal rosette of long-petioled, narrowly oval leaves with a heart-shaped base, deeply wrinkled surface, and coarsely toothed margins; the upright square stems bear smaller, shorter-stalked leaves and terminate in dense, oblong spike-like inflorescences of two-lipped reddish-purple to magenta flowers from July to September. Each calyx is 5–7 mm long with five bristle-tipped teeth and the corolla 10–15 mm long with a flat, nearly straight upper lip and projecting anthers. The fruit is a small dry nutlet enclosed within the persistent calyx. Native to Europe, western Asia, and northern Africa, betony grows in dry grasslands, hedge banks, open woodland, and heathy meadows, common throughout England and Wales but scarcer in Scotland and Ireland.
Active Constituents
Verbascoside (acteoside)
Phenylethanoid glycosideConcentration: Major phenylethanoid of the aerial parts
A principal antioxidant of wood betony with well-documented radical-scavenging, anti-inflammatory and neuroprotective activity; one of the phenylethanoid glycosides that dominate the herb's phenolic fraction.
Betonyosides A-F
Phenylethanoid glycosidesConcentration: Characteristic minor glycosides
Six phenylethanoid glycosides first isolated from and largely characteristic of Stachys officinalis (and S. recta), serving as chemotaxonomic markers and contributing to the antioxidant profile.
Leucosceptoside A/B, forsythoside B, campneoside II
Phenylethanoid glycosidesConcentration: Accompanying phenylethanoids
A suite of accompanying phenylethanoid glycosides isolated from the aerial parts that reinforce the antioxidant and anti-inflammatory activity of the herb.
Chlorogenic acid and caffeic acid
Hydroxycinnamic (phenolic) acidsConcentration: Chlorogenic acid a main antioxidant; caffeic acid ~3-4% of methanol extract
Chlorogenic acid is, with the phenylethanoid glycosides, one of the main antioxidant constituents responsible for the strong DPPH/ABTS activity of betony extracts.
Iridoid glycosides (8-O-acetylharpagide, allobetonicoside, harpagide)
Iridoid glycosidesConcentration: Characteristic minor constituents
Bitter iridoid glycosides typical of the genus that contribute to the herb's bitter-tonic and mild anti-inflammatory character.
Tannins
Polyphenolic tanninsConcentration: ~5-15% of the herb (reported ~5.5% pyrogallol-type in extract)
Condensed and hydrolysable tannins give betony its astringent action, underlying traditional use for wounds, mouth and throat washes and diarrhoea; high tannin content is also the basis of theoretical reduced absorption of some co-ingested drugs and minerals.
Betaine alkaloids (trigonelline, stachydrine)
Betaine / pyrrolidine alkaloidsConcentration: Minor
Small quantities of betaine-type alkaloids characteristic of the genus Stachys; stachydrine has been linked to mild uterine and cardiovascular effects reported across the genus.
⚠ Drug Interactions
Oral drugs, iron and alkaloid medicines (tannin binding)
The high tannin content of betony can bind alkaloids, iron and some drugs in the gut, theoretically reducing their absorption if taken together. A general property of tannin-rich herbs rather than a documented clinical event for betony.
Clinical note: Separate dosing of betony tea from oral medicines and iron supplements by ~2 hours.
Antihypertensive drugs / pregnancy
Betony is traditionally described as mildly hypotensive and as a uterine stimulant, so additive blood-pressure lowering and use in pregnancy are theoretical concerns. Human interaction data are lacking.
Clinical note: Traditionally avoided in pregnancy; use cautiously with antihypertensives.
Preparation Methods
Infusion (herbal tea)
Parts: aerial parts, leaves, flowering tops
Traditionally 1-2 g of dried aerial parts is infused in hot water and taken up to three times daily as a nervine and bitter tonic for tension headache, nervous tension and mild digestive upset. Best avoided in pregnancy owing to the herb's traditional uterine-stimulant reputation.
Tincture
Parts: aerial parts
An alcohol tincture of the dried herb is used by Western herbalists for headache, anxiety and neuralgia; typical traditional doses are small (a few millilitres) given its astringency.
Mouthwash / topical wash
Parts: aerial parts
The astringent, tannin-rich infusion has been used as a gargle for sore throat and mouth and as a wash for minor wounds and skin irritation.
Clinical Studies
Genus Stachys—Phytochemistry, Traditional Medicinal Uses, and Future Perspectives
Reviews the phytochemistry of the genus Stachys, identifying phenylethanoid glycosides (verbascoside, leucosceptoside A), phenolic acids (chlorogenic acid), iridoids (allobetonicoside, 8-O-acetylharpagide) and alkaloids (trigonelline) as characteristic, and links this profile to antioxidant, anti-inflammatory and neuroprotective activity underpinning traditional use of wood betony.
Antioxidant properties and phenolic composition of wood betony (Betonica officinalis L., syn. Stachys officinalis L.)
Chlorogenic acid, phenylethanoid glycosides and a hydroxycinnamic-acid derivative were identified as the main antioxidants. Methanol extract was the strongest radical scavenger (714 µmol Trolox equiv./g in DPPH), confirming the phenolic-driven antioxidant capacity of wood betony aerial parts.
Phenylethanoid glycosides from Stachys officinalis
Isolated six new phenylethanoid glycosides (betonyosides A-F) together with six known glycosides (acteoside, campneoside II, forsythoside B, leucosceptoside B and others) from the aerial parts, establishing the characteristic phenylethanoid chemistry of wood betony.
