Achillea millefolium Herb Identity & Part
The botanical entity is Achillea millefolium L., a perennial herb of the daisy family, Asteraceae, with finely divided feathery leaves and flat clusters of small white flower heads. The species name means thousand-leaved. The part used is the aerial portion, meaning leaves, stems and flowering tops, and the roots are not included in this yarrow extract. Achillea millefolium is treated as a group of closely related forms, so ornamental yarrows and other Achillea species should not be assumed to be the same material. Yarrow is known for flavonoids such as apigenin and luteolin glycosides, caffeoylquinic acids, bitter sesquiterpene lactones and an essential oil, and the water extract keeps the soluble members.
The plant spreads by rhizomes and grows in meadows across the northern hemisphere, so wild-collected and cultivated material both enter trade.
