LUNARIA, SATTIN-FLOWER, or Moonwort, in botany: A genus of the filiculosa order, belonging to the tetradymania class of plants; and in the natural method ranking under the 39th order, Siliquese. The filicula is entire, elliptical, compressed-plane, and pedicellate; with the valves equal to the partition, parallel and plane; the leaves of the calyx are alternately fringed at the base. This plant is famous in some parts of the kingdom for its medicinal virtues, though it has not the fortune to be received in the shops. The people in the northern countries dry the whole plant in an oven, and give as much as will lie on a shilling for a dose twice a-day in hemorrhages of all kinds, particularly in the too abundant flowing of the menses, and with great success. The Welch, among whom it is not uncommon, Dr Needham informs us, make an ointment of it, which they use externally, and pretend it cures dysenteries.
