Coffee contains caffeine, which is a natural stimulant that helps in increasing mental alertness as it works on the central nervous system (CNS). It is extracted by a process called infusion, steeping the plant product in water. It is found in the seeds, nuts, or leaves of around sixty plant species. Common sources are the “beans” (seeds) of the two cultivated coffee plants, Coffea arabica, and Coffea canephora.
