Except for extremely rare examples that I don't expect to encounter, there are no other wild species of this genus in the bay area.
Various sources, both ancient and modern, claim that crushed yarrow leaves and flowers (fresh or dry) are good for stopping bleeding. [source] You can chew it up to make it stickier. [source] Achilles supposedly used it on his men’s battle wounds, thus lending his name to the genus. [source]
