96 CASSIA. No. IS 



so active as rhubarb or jalap. This kind operates with 

 mildness and certainty^ at the dose of an ounce in de- 

 coction : both the leaves and pods arc employed ; the 

 infusion is weaker, the tincture is less available, al- 

 though stronger. They may enter into coinpound 

 laxatives and cathartics, &:c. 



Substitutes — Senna — Cassia fistula — Rhubarb 

 Juglans Cinerea — Todophyllum pdtatum — Castor 

 oil, and all mild purgatives, besides the following spe- 

 cies of Cassia ; which arc, however, still left active. 



Remarks — Clayton and vSehoepf, mentions the C, 

 ligustrhia as equal to Senna : it grows from Virginia 

 to Georgia, has seven pairs of lanceolate, unequal fo- 

 Holes, and oblong curved pods. 



C. chamecristuy small plant found every where iti 

 dry soils ; it has many pairs of linear foHoTes, and 

 large geminate flowers with two purple spots- 



C. nktifan^'y or sensitive Senna, similar to the fore- 

 going, but with vQ^vy small flowers : common. 



C. taroidesy N. Sp. or sickle Senna, is perhaps the 

 C. tora of some botanists ; found from Georgia to 

 Kentucky, it has three pairs of ovate folioles and Ion 

 fulcated axillary pods. 



All the American Sennas have yellow 6owers. 

 Schoepf, says that the C. bijlorais antisyphilitic 



cr 



Henry's tigure of the American Senna is fictitious, 

 having four pairs of folioles and regular terminal 



\

flowers.
