  • Caffeine is the most popular and widely used drug in the world. It is a substance found in the leaves, seeds or fruit of a number of plant species, such as coffee and tea plants. Caffeine is a stimulant which acts on the central nervous system to speed up the messages to and from the brain. It is made up of the elements carbon, hydrogen, nitrogen and oxygen (C 8 H 10 N 4 O 2 ). Its chemical name is 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione (or 1,3,7-trimethylxanthyine for short).

  • Hello Caffeine (sometimes called guaranine when found in guarana, mateine when found in mate, and theine when found in tea) is a xanthine alkaloid found in the leaves and beans of the coffee tree, in tea, yerba mate, guarana berries, and in small quantities in cocoa, the kola nut and the Yaupon holly. In plants, caffeine acts as a natural pesticide that paralyses and kills many insects feeding upon them. The name is derived apparently from Italian caffè ("coffee") plus the alkaloid suffix -ine. Caffeine is a central nervous system (CNS) stimulant, having the effect of warding off drowsiness and restoring alertness. Beverages containing caffeine â?? such as coffee, tea, soda and energy drinks â?? enjoy popularity great enough to make caffeine the world's most popular psychoactive drug. In nature, caffeine is found with widely varying concentrations of the other xanthine alkaloids theophylline and theobromine, which are cardiac stimulants. When caffeine appears to have different effects depending on the source, it is due primarily to varying concentrations of other stimulants and absorption rates of the mixture. http://en.wikipedia.org/wiki/Caffeine
