Principle
Tea and coffee contain caffeine, an alkaloid which acts as a stimulant. Solid caffeine is converted directly to the gaseous state on heating, without any intermediate liquid state. It sublimes. Caffeine is harmful to health when consumed in larger quantities. Caffeine is detected in coffee, coffee substitute and tea.
