196^ TREATMENT OF 



§ OXVII. Convolvulus Jalappa.[^y) Jalap. 

 The resinous acrid princijile of tliis root, which has 

 a disagreeble smell and nauseous taste, is proba- 

 bly the cause of its anthelmintic virtue. Wep- 

 ffr,{2S} after having employed without success the 

 remedies most celebrated against the taenia, suc- 

 cessfully prescribed to one of his patients half a 

 drachm of this root in powder. It is commonly di- 

 rected in combination with other remedies. ('^9) 



§ CXVllI. Jlngelicae cortex.{SO^ Angelica, 

 the bark. Dr. Grieve{-ii) was the first who gave 

 this article as an anthelmintic, particularly against 

 the lumbricoides. An ounce of this bark is boiled 

 in three pounds of water, to one pound ; of which 

 decoction the patient takes every morning, one or 

 two ounces. 



This remedy has sometimes occasioned griping 

 pains ; it has however occasionally expelled an ex- 

 traordinary quantity of w^orms. 



^ CXIX. Ferula AssafoetidaJ 22) Thegum- 

 mi-resinous juice, obtained from incisions of the 

 root of this plant, is what is used in medicine for 

 the cure of several diseases, and particularly for 

 the purpose of relieving the human body from 

 Worms, and those spasmodic affections from sym- 

 pathy, which result from them. The virtues of 

 this substance reside in the volatile oil and resi- 

 nous principle which it contains. 



Its taste is somewhat sharp, aromatic, andnau' 

 scous ; it diffuses a smell of gariick.
