Achillea ageratum (also known as Sweet Maudlin, Sweet Yarrow, or Sweet Nancy) is a flowering plant in the family Asteraceae, native to southern Europe and cultivated as a fragrant herb. In the Middle Ages it was used as a strewing herb to repel insects such as moths, lice and ticks and spread a good smell in private rooms.
