Scammony, Dr. Withering favs, is the infpiffated juice of a 
fpecies of Convolvulus fo mu^ refembling this, “that they are 
with difficulty diftinguifhied. © Can it then, fays he, be worth 
while to import Scammony from Aleppo, at a confiderable an- 
^nual expence, when a medicine, with the very fame properties, 
grows fpontaneoufly in many of our hedges ? . If the prepa- 
ration of Scammony ‘would be a faving to England, it muft 
‘certainly be a much greater to America, in proportion to the 
quantity ufed. — Befides, as.the imported Scammony is often very 
:ámpure, and as there is fo much difference in the purgative vir~ 
-tue of fome maffes of it, and that of others, that it is feldom 
to be depended upon alone: im extemporaneous practice, might 
it not be prepared here-much purer, and be more uniform in 
its virtue ? | Notwithftanding the roots of the Convolvulus is 
.a very acrid purgative to the human race, hogs will eat it ia 
"large quantities without any ill effects.
