The cacao bean is another common plant that has long been used for the effects of caffeine. Ancient writings in Mexico have proven that the Olmecs, who lived in Mexico between 1500 and 400 B.C.E., were the first to use the cacao bean. The Olmecs harvested wild cacao pods to make a chocolate drink. Following the Olmecs, the Maya became very wealthy trading cacao. Within Mexico, chocolate was then passed on to the Toltecs and the Aztecs in the twelfth century.
