Chocolate

Chocolate is a psychoactive food. It is made from the seeds of the tropical cacao tree. The cacao tree was named by the 17th century Swedish naturalist, Linnaeus. The Greek term theobroma means literally "food of the gods". Chocolate has also been called the food of the devil; but the theological basis of this claim is obscure.

        Cacao beans were used by the Aztecs to prepare a hot, frothy beverage with stimulant and restorative properties. Chocolate itself was reserved for warriors, nobility and priests. The Aztecs esteemed its reputed ability to confer wisdom and vitality. Taken fermented as a drink, chocolate was also used in religious ceremonies. The sacred concoction was associated with Xochiquetzal, the goddess of fertility. Emperor Montezuma allegedly drank 50 goblets a day.

coffee

Ethiopian 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 natives 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 discovered coffee, did not appear in writing until 1671 and is probably apocryphal.
