What does «cafeína» mean in Spanish?
- Alkaloid extracted from coffee, tea, mate, etc., used as a cerebral and cardiac stimulant. Caffeine is the main stimulant contained in coffee. Its action is exerted on the brain and nervous system and generally produces a sensation of well-being. The caffeic acid is rather a chlorogenic acid than a tannic acid, which contributes to the astringency of the beverage.
