CIASS X. Decocta. DECOCTIONS. 



Decoctions and infusions differ chiefly 

 in the employment of boiling or of cold 

 water. At the same time, however, that 

 the increase of temperature in decoctions 

 facilitates and expedites the solution of 

 some fixed principles, it gives others a 

 tendency to decomposition, and dissi- 

 pates all volatile matters. Decoction, 

 therefore, can only be used with advan- 

 age for the extraction of principles which 



are neither volatilized nor altered by a 

 boiling heat. 



To promote the action of the menstru- 

 um, infusion is sometimes premised to 

 decoction. 



In compound decoctions it is sometimes 

 convenient not to put in all the ingredi- 

 ents from the first, but in succession, ac- 

 cording to their hardness, and the diffi- 

 culty with which their virtues are ex- 

 tracted ; and if any aromatic, or other sub- 

 stances containing volatile principles, en- 

 ter into the composition, the boiling de- 

 coction is to be simply poured upon them, 

 and covered up until it cool. 



Decoctions should be made in vessels 

 sufficiently large to prevent any risk of 

 boiling over, and should be continued 

 without interruption, and gently.

 class are

 coction of marsh mallows.

CLASS XI. Infusa. INFUSIONS. 



We have already explained the sense 

 in which we employ the term infusion. 

 We confine it to the'action of a menstru- 

 um, not assisted by ebullition, on any sub- 

 stance consisting of heterogeneous prin- 

 ciples, some of which are soluble, and 

 others insoluble, in that menstruum. The 

 term is generally used in a more exten- 

 sive, but, we are" inclined to think, a lc~ 

 correct sense. Thus, lime water and
