Obs. Formerly used as a remedy for " internal wounds," and still has 

 some reputation in diseases of the lungs and bowels. The root is the

Ohs. A worthless little foreigner, more noticeable for its frequency in 

 our fields, than for any intrinsic importance, even as a weed. According 

 to the doctrine of signatures — a fanciful theory of the early days of 

 medical science, which assumed that all n.edicinal subs-tances indicated 

 by some external character the diseases to which they were adapted, or 

 the part of the body which they were supposed to affect — this, and other 

 species, were formerly a reputed cure for the stone in the bladder, from the 

 stony-like appearance of its seeds ; whence one of the popular names.
