(western) pearly everlasting, Perlkörbchen, Perlblume, Silberimmortelle
Erect rhizomatous perennial, up to 90cm tall, native to North America, northeastern Asia, cultivated elsewhere as ornamental; leaves lanceolate or linear, sessile, acuminate, commonly less pubescent above than beneath, or glabrous above, margins often revolute; basal and lower cauline leaves soon deciduous; flowers terminal, clustered in short, broad inflorescences; flower heads 1 cm wide or less, numerous and crowded in a short broad inflorescens, involucre 5-7mm, bracts pearly-white; achenes papillate; seeds very fine, almost dust-like.
„Anaphalis margaretacea was widely planted as an ornamental and escaped. It apparently naturalized from its native range in both Asia and North America; it is cultivated and naturalized in Europe.“
The herb is used as an expectorant and astringent, especially in homeopathy.
From the leaf and stem exudate (aceton extract of brownish resin of dried plant material) of A.margaritacea a number of flavonoid aglycones was isolated: Galangin-3-methyl ether, 6-hydroxy-galangin-3,6-dimethyl ether, 8-hydroxygalangin-3,8-dimethyl ether (gnaphalin), quercetin, 6-methoxy-galangin, 3,5,7-Trihydroxy-6,8-dimethoxy flavone, 5,7-dihydroxy-3,6,8-trimethoxy flavone (araneol), 5,7-dihydroxy-6-prenyl flavanone (6-prenyl-pinocembrin), 2',4',6'-trihydroxy-3'-prenyl-chalcone, 3,5-dihydroxy-6,7,8-trimethoxy flavone, galangin, and 8-methoxy galangin.
