The family flora and materia medica botanica: containing the botanical analysis, natural history and chemical and medical properties of plants . rebral congestionand dropsical affections, by a counter-irritant influence on the mu-cous membrane, jalap is well adapted to fulfil it. Jalap, (saysBremser,) is without contradiction in verminous diseases, one of thebest purgatives and which perhaps possesses at the same timegreater anthelmintic virtues than any other. Jalap is apt to be attacked by worms, which however are said todevour the amylaceous or softer parts and to leave the resin, so thatthe worm-eaten drug is more powerfully purgative than that whichis sound. Thus out of 397 parts M. Henry obtained 72 parts ofresin, while from an equal quantity of the latter he procured only48 parts. Hence worm-eaten jalap should be employed for obtain-ing the resin, but should not be pulverized, as it would afford apowder of more than the proper strength. The dose of jalap in powder is from fifteen to thirty grains, of theresin or alcoholic extract from four to eight grains. The latter isusually given rubbed up with sugar, or in Hydrastis Golden seal ... V* RANUICULACE^. Cr owfoots. N°- CANADENSIS. Turmeric-root. Golden seal, Yellow-root, Orange-root.
