Way to qualify its Force, let it be diluted with a 
fufficient Quantity of Liquor. And this may be 
underftood of Purgatives in general. As to Jalap, 
it wants no Corrector, fince its faline and fulphu- 
reous Parts are extended by a fufficient Quantity 
of Earth ; infomuch that no Preparation thereof is 
better than the Root in Powder. A Refin is got 
from it with Spirit of Wine, and a gummous Ex- 
trad with Water. However, the Refin purges no 
more, but, on the contrary, fometimes, lefs than 
the Root, and always occafions Pains and Gripings
