Yarrow (achillea millefolium)- this fragrant, flowering plant has been used since ancient greece began using to stop excess bleeding. it is said the greek hero achilles used it on his wounds, hence the name. pioneers and aboriginal people applied this on open wounds and cuts as a poultice made from the leaves to help clot the blood. they also combined fresh yarrow juice with water to help an upset stomach and for intestinal disorders. a tea made from the leaves and stems will act as an astringent.
