Spigelia, Pink Root. In large doses (i.e., I to 2 f3 for adults; for children, ro to 20 I.) spigelia is a powerful anthelmintic, but must be used with care, since it is decidedlv narcotic and excites the circulation. Combined with senna, it is highly efficient in removing lumbracoid worms.
In small doses (tr. or @, 5 111.) it is suggested in neuralgia of the fifth nerve, neuralgic heart affections, pericarditis, and rheumatic endocarditis, but has no established place in therapeutics. Its physiologic action would warrant using it in these difficulties.
