No. 224.—Decocra. Decoctions. 
These are the impregnated solutions of medicines, in which 
their activity is obtained by coction. They are only to be 
ih: made of medicines, the virtues of which are soluble in 
2 water, not vaporjzable, nor existing in extractive matter: 
the latter would become inert by long boiling. The drugs 
should be bruised or sliced, completely covered with 
water, and the vessel closely fitted with a cover; the coc- 
tion should be slowly, regularly, and uninterruptedly con- 
tinued for some time. In compound decoctions, those 
_ substances should be first put in, which are the hardest 
_ and require the longest coction—and so on, successively, 
with those the virtues of which are most speedily extract- 
ed. If volatile substances are to form a part, the decoction, 
prepared, should last of all be poured over them, 
and covered until cold. The proportions must be 
ed by the known nature of the ingredients. Asa generat
