Botanical Description
Achillea nana, the dwarf alpine yarrow, is a small, mat-forming perennial herb in the family Asteraceae native to the high mountains of central and southern Europe, where it occupies stony slopes, scree, moraine, and short turf in the alpine and nival zones, typically above 2000 m elevation. Plants grow only 5-15 cm tall, with creeping rhizomes giving rise to dense tufts of densely silver-tomentose, narrowly oblong, finely pinnately-divided leaves whose ultimate segments are short and crowded. From midsummer the short flowering stems carry compact, flat-topped corymbs of small, dingy-white to cream flower heads with five or six short, broad ray florets surrounding a dense disc. The whole plant is intensely aromatic when bruised, with a pungent, slightly camphoraceous scent characteristic of the genus. It is well-adapted to extreme cold, drought, and high ultraviolet exposure.
Active Constituents
Proazulene sesquiterpene lactones / chamazulene
Sesquiterpene lactone (guaianolide) and its azulene derivativeConcentration: Present (not species-quantified)
Like other members of the yarrow group, alpine Achillea contain matricin-type proazulenes that convert to blue chamazulene on distillation; chamazulene and chamazulene-carboxylic acid are anti-inflammatory. Direct quantitative data specific to A. nana are limited.
Camphor
Monoterpene ketoneConcentration: Documented at genus level; not quantified for this species
A characteristic monoterpene ketone of the essential oils of European Achillea; contributes counter-irritant and antimicrobial activity.
1,8-Cineole
Monoterpene oxideConcentration: Documented at genus level; not quantified for this species
A commonly reported oxygenated monoterpene of Achillea oils with expectorant, anti-inflammatory and antimicrobial properties.
Flavonoids and phenolic acids
PolyphenolsConcentration: Present (qualitative)
Achillea species characteristically accumulate flavonoids (apigenin, luteolin glycosides) and caffeoylquinic acids that provide antioxidant and anti-inflammatory activity; these are reported for the genus but not specifically quantified for A. nana.
Preparation Methods
Alpine folk infusion
Parts: Flowering aerial parts
In alpine folk practice the aromatic flowering tops of dwarf yarrows are infused as a bitter digestive and appetite tonic. As with all Asteraceae, sensitised individuals may react; internal use in pregnancy is traditionally avoided.
