This herb grows wild in wet land, and may be often found among the grass, and at the edges of plough fields. It grows from four to twelve inches high; the leaves are rather smaller than mint leaves; it bears a kind of bur containing seed, which grows round the stalk at each joint. There are two kinds which grow near each other; they look very much alike, but are very different in taste. One is very bitter and the other has no bitter taste, but is very rough and of a balsamic taste. They may be used together in a tea or syrup, and answer two important purposes; the rough removes the canker, and the bitter is a corrector of the bile. By adding No. 2, the compound contains the three great principles of the healing art, viz: hot, rough and bitter.

These remedies are of great value in the menstrual flow and in dysmenorrhoea. It is a uterine antispasmodic. Dose of tincture, 15 to 30 minims.
