BOTANIC MATERIA MEDICA, 353 
The odor of the oil is of its own kind; taste, 
Sweet, aromatic and warm Most of the com- 
mercial Anise Oil is that distilled from the Star 
Anise. The marketable value of the oil is, of 
course, an invitation to adulterate it, and the 
most common foreign bodies thus employed are 
spermaceti, paraffin and camphor. The first 
two may be distinguished by the insolubility, 
but when the oil is treated with alcohol, the 
camphor can only be detected by the odor. 
The oil, like the seed, is carminative and 
stomachic in its action, and whilst rarely admin- 
istered alone, it is a favorite ingredient in the 
following officinal preparations: AQuA ANISI, 
SPIRITUS ANISI SYR. SARSAPARILLA COMPOSITUS, 
TINCT, OPII CAMPHORATA, TROCHES Of GLYCER- 
RHIZA ET OPI, etc. 
Oleum Anthemidis, Camomile Oil; distilled 
from the flowers of the Anthemis Nobilis.— 
Natural order Composite. The plant has al- 
ready been described under the head of flowers, 
therefore repetition is unnecessary. It is said 
that it requires 80 or more pounds of flowers to 
yield an ounce and a half of the oil. When first _ 
prepared it is a pale-blue color, but by age it 
gradually becomes yellow, with a penetrating, 
aromatic odor of the flower much intensified; 
taste, bitter, pungent and aromatic; having a 
specific gravity of 0.983, and containing a com- 
pound of angelic and teglinic acids, also hevyl; 
esamyl, and tsobutyl tethers. 
This oil must not be confounded with that ob- 
tained from the German Camomile (Matricaria 
Chamomilla), which is much employed, and sold 
under the name of Camomile Oil, the former
