Caption: Caffeine crystals. Polarised light micrograph of crystals of caffeine (1,3,7- trimethylxanthine). Caffeine stimulates the central nervous system increasing alertness and deferring fatigue. It is often contained in analgesic (pain relief) preparations with aspirin or codeine to counter the drowsiness that these drugs can cause. Caffeine is also a diuretic, (it increase the removal of water from the body) and has laxative properties. It is widely known for its presence in coffee beans and tea leaves.
