Yarrow Achillea millefolium

An erect perennial herb, yarrow produces one or more stems of up to 3 feet high. The leaves, which are from 2 to 8 inches in length, are feather-like and arranged spirally on the stems. The ray (three to eight in number) and disc (15 to 40 in number) flowers are white to pink.
In antiquity, yarrow was the go-to herb for staunching blood.

6 tablespoons of the dried leaf in 2 1/2 cups water. For migraine, place leaves in nostrils. This will cause bleeding, but relieve pressure. For toothache, chew fresh leaves. For acne and other skin conditions, make a decoction of
1/2 cup leaves in 2 cups boiled water; cool and wash with it. You can drink this warm or cool for all conditions. To stop bleeding on small- to moderate-sized cuts, place a leaf on the affected area. For larger cuts (when proper first aid is not available), make a plaster by chewing on several leaves, and gently pushing them into the wound.
