According to encyclopedias, caffeine is a xanthine alkaloid compound* that acts as a psychoactive stimulant* in humans. It is found in beans, leaves, and the fruit of over 60 plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. It is most commonly consumed by humans in infusions extracted from the beans of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut or cacao.
