Yarrow (Achillea millefolium) is a very aromatic but bitter medicinal herb native to Asia, Europe, and North America. Historically it’s been used topically, for its healing properties on wounds.
Yarrow was also one of the main bittering agents used in Old World beers before the introduction of hops. From experience, probably due to location and soil conditions, the flavors of yarrow can range from mild to overwhelmingly bitter, so you may need to adjust the recipe a bit.
Thanks to its strong aromatic qualities, yarrow is also making a comeback as a culinary herb.
