Historical sources compliment the findings of archeology. The chroniclers, avid from their perspective to describe the habits, customs, histories and resources of the New World, saw the importance that Coca had in the world which they described. Shozo Masuda, in a detailed treatment of some of the texts of the chroniclers of the 16th and 17th centuries, ordered the testimonies of the Spanish about the Coca leaf. (1984). On the use and consumption of Coca, the chroniclers noted the profound place the leaf had in Andean religious life. Coca was adored like a deity and daughter of the Pachamama (Mother Earth). But its principal use was as an offering to the sun, the Pachamama and to other gods, to sacred sites (huacas and apachetas), to persons and to long-standing concepts.

As well as this, offerings were given in particular circumstances, such as to ask favour of the elements (rain or sun), in other agricultural rites or to celebrate the end of a job of work (challa). There were various different procedures for these offerings. The leaves were buried, chewed or even soaked in chicha (corn beer).
