The action of this variety of Silphium, if we are to believe the reports of the few who use it, is very direct and certain upon the chylopoietic viscera. It is claimed that it is one of the best remedies in the treatment of ague-cake, and congestion of liver and spleen, so frequently associated with chronic intermittents. It is but little employed, but deserves thorough investigation.
