Caffeine

Caffeine is a central nervous system stimulant of the methylxanthine class.  It is the world's most widely consumed psychoactive drug. Unlike many other psychoactive substances, it is legal and unregulated in  nearly all parts of the world.  Caffeine also stimulates certain portions of the autonomic nervous system.




Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine bases of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It is found in the seeds, nuts, or leaves of a number of plants .  Beverages containing caffeine are ingested to relieve or prevent drowsiness and to improve performance.  Caffeine can have both positive and negative health effects. It can treat and prevent the premature infant breathing disorders bronchopulmonary dysplasia of prematurity and apnea of prematurity. Caffeine citrate is on the WHO Model List of Essential Medicines.  It may improve weight gain during therapy and reduce the incidence of cerebral palsy as well as reduce language and cognitive delay. On the other hand, subtle long-term side effects are possible.
