What did the Aztecs use coco beans for?

The Aztecs didn't use "coco beans". They used cacao beans, which are the seeds of the cacao tree.

The Aztecs used cacao beans for:

* A bitter beverage: They ground the beans and mixed them with water, spices, and sometimes chili peppers to create a drink called xocolatl (pronounced "cho-co-latl"). This drink was considered sacred and was often used in religious ceremonies.

* Currency: Cacao beans were used as a form of currency in Aztec society.

* Medicine: They believed cacao beans had medicinal properties and used them to treat ailments like fatigue, fever, and diarrhea.

* Food: Cacao beans were also used to flavor food and create a paste called mole.

It's important to note that the Aztecs' use of cacao was quite different from how we use chocolate today. Xocolatl was a bitter beverage and not the sweet treat we enjoy. It was also reserved for the elite and not consumed by the general population.
