The systematic name of the Stavesacre, Staphisagria, Phtheiroctonum, Phtheirium, Staphis, Pedicularia, (F.) Staphisaigre, Herbe aux Poux, Dauphinelle. The seeds, Staphisagria, (Ph. L. and E.) have a disagreeable smell; a nauseous, bitterish, hot taste; and are cathartic, emetic, and vermifuge: owing, however, to the violence of their operation, they are seldom given internally, and are chiefly used in powder, mixed with hair powder, to destroy lice. The active principle of this plant has been separated, and received the name Delphinia, (F.) Delphine, Delphinine. It is extremely acrid, and has been recently used, like veratria, in tic douloureux, paralysis and rheumatism. It is used in the form of ointment, or in solution in alcohol, (gr. to xxx, or more, to) applied externally.
