Coffee owes its stimulating proper- 
ties to an alkaloid caffeine which occurs 
in the beans as well as in other parts of 
the plant. Caffeine also occurs in other 
plants ;it is the active principle in Guar- 
ana and is perhaps identical with theine, 
the active principle of tea. It isgenerally 
believed that moderate coffee-drinking 
is beneficial rather than otherwise. It 
has ever been the favorite drink of 
those actively engaged in intellectual 
work. It has been tested and found 
satisfactory as a stimulant for soldiers 
on long or forced marches. Injurious- 
effects are due to excessively strong 
coffee, or a long-continued use of cof- 
fee which has been standing for some 
time and which contains considerable 
tannin. Caffein has been found very 
useful in hemicrania and various ner- 
vous affections. It has also been rec- 
ommended in dropsy due to heart le- 
sion. Strong, black coffee is very val- 
uable in counteracting poisoning by- 
opium and its derivatives. Coffee will 
also check vomiting. Strong coffee is- 
apt to develop various nervous trou- 
bles, as palpitation of the heart, sleep- 
lessness, indigestion, trembling. Ac- 
cording to one authority, it is the 
aromatic principle of coffee which 
causes sleeplessness.
