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 activeprincipleof tea. It isgenerally 

 believed that moderate coffee-drinking 

 is beneficial rather than otherwise. It 

 has ever been the favorite drink of 

 those actively engaged m 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.
