Yarrow, the Common, or Milfoil, Achillea Millefolium, L. an indigenous perennial, growing in meadows, pastures, and on road-sides ; blowing from June till August.; - The flowers of this vegetable yield an essential oil, which possesses an aromatic odour, a bitter taste, and is similar to that of chamomile. - A decoction of its leaves with chamomile flowers is said to form a corroborant diet-drink for children who, on account of their rapid growth, are unable to retain their water, during the night: but, for this purpose, from one to two pints of such preparation ought to be taken in the course of 24 hours. - LiNNAEUS observes, that the Dalecarlians have a practice of throwing the flowers and leaves of the common yarrow into beer, while in a state of fermentation; with a view to increase its intoxicating effects. - Bautsch, in Germany, has usefully employed the whole herb, in the process of tunning.
The Milfoil, being a creeping plant, which spreads uncommonly from its numerous seeds, it often becomes a troublesome weed, if it be once suffered to grow in fields. Nevertheless, Dr. Anderson recommends its culture as a proper food fur cattle. - It is eaten by sheep and hogs; but is relished neither by horses, cows, nor goats.
