Plate 26. Eupatorium cannabinum.

A tall plant growing by waters, with tufts of red flowers and leaves, divided in the manner of those of hemp. It grows five feet high; the stalk is round, thick, reddish, and very up right. The leaves are large, of a pale green, and fingered; they stand two at each joint; the flowers grow in bunches as big as a man's fist, on the tops of the branches, and are of a bright red.

The root fresh gathered and boiled in ale is used in some places as a purge; it operates strongly, but without any ill effect, and dropsies are said to have been cured by it singly.

The Family Herbal, 1812, was written by John Hill.
