i-coffee is a brewed beverage prepared from the roasted seeds of an evergreen shrub of the genus Coffea. Caffeine is a major active component present in coffee, basically serves as a stimulant at normal dose. Humans typically consume coffee to temporarily increase mental alertness and/or reduce physical fatigue. A cup of i-coffee refreshes the mind and supports healthy blood sugar level in humans.
According to legend, ancestors of today's Oromo people were believed to have been the first to recognize the energizing effect of the coffee plant, though no direct evidence has been found indicating where in Africa coffee grew or who among the native populations might have used it as a stimulant or even known about it, earlier than the 17th century. The story of Kaldi, the 9th-century Ethiopian goatherder who supposedly discovered coffee when his goats behaved strangely after eating from a coffee plant, did not appear in writing until 1671 and is probably apocryphal.
