Yarrow never debilitates the patient and has tonic qualities that help to purify the blood. It's also used to help digestion and was well known by the Shakers as a digestive and general tonic. As a cosmetic, yarrow makes an effective skin cleanser and toner because of its astringency. Yarrow tea made with flowering stems is said to be beneficial to oily skin. The plant is native to Europe and was naturalized in North America.
Common yarrow is found in pastures, roadsides, embankments, and waste ground.
Leaves are aromatic and finely divided, clasping the stem toward the top, while the lower leaves are stalked. Millefolium refers to leaf segments. If picked on hot days, it is said the leaves feel very cool and are fragrant. There are several plant varieties that range in height from eight inches to five feet. Yarrow is easy to grow and will self-sow, which some gardeners find invasive.
