ART. LIX. — TROCHES OF IPECACUANHA. 
It appears, that by following the directions given in the 
formula of the Codex Medicament arius for making this pre- 
paration, the saccharine paste is extremely apt to be of a more 
or less deeply marked gray colour, in consequence of the affi- 
nity between the extractive principle of the Ipecacuanha and 
the water of the mucilage. The endeavour to improve the 
appearance of the medicine, made by various French pharma- 
ceutists, who directed their attention to the subject, appeared 
to be unsuccessful, until a method was recently proposed by 
M. Vaudamme, of Hanzebrouck, by which, from his state- 
ment, the desirable degree of whiteness is secured; this me- 
thod, followed by the adequate extent of desiccation by a 
stove, produced a handsome article perfectly white. It is as 
follows: 
Take of Pulverized Ipecacuanha, 12 grammes. 
Very white sugar, 365 " 
Gum arabic, 20 " 
Pure starch, 96 " 
Orange flower water, 40 " 
A mucilage is first made with the starch and orange flower 
water; the ipecacuanha is intimately mixed with a part of the 
sugar, the gum arabic and the remainder of the sugar are in- 
corporated into the mucilage, and finally the process is con- 
cluded by the addition of the Ipecacuanha and sugar united, 
the whole forming a homogeneous paste, to be divided into 
cakes of two grains each.
