Cavadilla, a plant but little known, though its seeds have long been applied externally to destroy vermin; as they produce a considerable irritation in the skin. Lately, however, the celebrated Schmucker has successfully administered these seeds internally for the same purpose, in the following manner : Half a dram of the powder mixed with honey, was ordered to be taken, on an empty stomach, for five successive mornings ; after which he prescribed a brisk laxative. By this treatment, the cavadilla has, by several Continental physicians, been observed to expel the ver-solitaire, or solium, a species of tape-worm extremely difficult to be removed. It is farther affirmed, that in a variety of cases it uniformly produced that effect.
