There are a group of unrelated plants that were discovered by different groups around the world as having medicinal properties and Yarrow is one of those plants. Aloe vera, Neem trees, Stinging Nettle, Comfrey, etc. are just a few in this group.
What's even more fascinating is that the timespan is fairly close, i.e. over a 500 year period more or less and for many groups they were isolated and had little contact with the other groups and plants.
Plants today are and have been the major source of pharmaceutical medicines. Remember the discovery of Taxus from the Yew tree a few years back? That one save a huge amount of ancient forests in Oregon.
