sanicle, or self-heal, in botany: A genus of the digynia order, belonging to the pentandria clasps of plants; and in the natural method ranking under the 4th order, Umbellata. The umbels are close together, almost in a round head; the fruit is scabrous; the flowers of the disk abortive. There are three species, viz. the canadensis, marilandica, and europaea, found in many parts both of Scotland and England. This plant was long celebrated for its healing virtues; but it is now totally disregarded.
