Verbesina
Also known as Crown beard, Gravel weed, Frostweed, Iceweed, White crownbeard.
Verbesina virginica, commonly called frostweed, crown beard or gravel weed, is a tall perennial composite native to the southeastern and south-central United States, named for the delicate ice ribbons that extrude from its split stems in early frost. The dried aerial parts and root were used by nineteenth century American Eclectic physicians, who valued the plant chiefly as a bitter tonic and as a folk remedy for urinary gravel, a use reflected directly in its common name. It never entered mainstream European or official pharmacopeial use and remains a minor, regionally known remedy today.
