MUCILAGES — SYRUPS 25 



MUCILAGINES — MUCILAGES 



Mucilages are aqueous adhesive liquors or jelly-like preparations 

 containing a viscid substance (gum or starch) either in solution or 

 suspension. All mucilages are prone to decomposition and on this 

 account should be freshly prepared for internal use. The following 

 are official : 



Mucilago Acacise Mucilage of Acacia. 



Mucilago Tragacanthse Mucilage of Tragacanth. 



SYRUPI — SYRUPS 



Syrups are concentrated solutions of sugar in vpater usually medi- 

 cated or flavored. A concentrated aqueous solution of sugar in water 

 is called " syrup " or " simple syrup." If the substance added to 

 to the simple syrup is a pleasant fruit or aromatic, the product is 

 termed a " flavored syrup" while if the material added is of a medi- 

 cinal nature, the product is a " medicated syrup." There are 22 

 official syrups. Many of these are of but little importance so a list 

 will not be given. According to the method used in manufacture, 

 syrups may be classified as follows: 1. Solution with heat, e.g., 

 Syrupus Calcis. 2. Agitation of sugar with medicated liquids or 

 simple admixtures without heat, e.g., Syrupus Pruni Virginianse. 

 3. Simple addition of medicated liquids to syrup, e.g., Syrupus 

 Zingiberis. 4. Maceration or digestion, e.g., Syrupus Picis Liquidse. 



MELLITA — HONEYS 



Honeys are thick liquid preparations containing medical agents 

 blended with honey. In the early days of medicine they represented 

 the most popular class of medical preparations, but have now been 

 almost entirely replaced by the elixirs and syrups. The U. S. P. 

 recognizes 3 official honeys. 



Mel Honey 



Mel Depuratum Clarified Honey 



Mel Eosse Honey of Kose 



EMULSA — EMULSIONS 



Emulsions are aqueous preparations for internal use, in which 

 resinous or fatty substances are suspended by means of mucilage or 

 other viscid material. Acacia, Tragacanth and Yolk of Egg are 

 often used for this purpose (Emulsifiers). In some instances, as in 

 the case pf emulsions of gum resins, the gum needed to form the 

 emulsion is found present with the resin. The seeds of some plants
