kuka

The word coca entered English in the 1570s via Spanish coca, itself borrowed from Quechua kuka — the native Andean name for the shrub Erythroxylum coca. A parallel Aymara etymology is also proposed: in Aymara, the term coca or khoka means simply 'plant' or 'tree,' suggesting that Andean peoples named the coca leaf with the most generic term available, the way one would say 'the plant' when everyone already knows which plant is meant. This linguistic plainness is itself revealing: coca was not a curiosity or an exotic import in the Andes but the most ordinary and essential vegetable matter in daily life, as unremarkable as bread. Its name required no elaboration because its presence required no explanation.

For Quechua-speaking peoples of the central Andes — in present-day Peru, Bolivia, and Ecuador — coca had been cultivated and consumed for at least four thousand years before European contact, with archaeological evidence of coca use pushing that estimate toward eight thousand years. The Inca state regarded coca as sacred, monopolized its cultivation on the eastern slopes of the Andes (the yungas, the cloud-forest transition zone at ideal altitude for the shrub), and distributed it ritually as part of the state economy. Coca leaves were burned as offerings to Inti the sun god, placed in the mouths of mummies, scattered before construction began, and chewed at altitude to suppress hunger and relieve the effects of thin air. The alkaloids in the leaf — primarily cocaine, but also other compounds — are genuine physiological aids at high elevation: they increase oxygen uptake efficiency, reduce fatigue, and dull cold and hunger. For people working at four thousand meters, the leaf was medicine.

Spanish missionaries and colonists arrived in the 1530s with profound ambivalence toward coca. The first instinct was to ban it as an obstacle to Christian conversion — the leaf was too tied to Inca religion, to the huacas (sacred sites), and to the mita labor system to be easily separated from what the Spanish regarded as paganism. But Andean mine workers, forced into the silver mines of Potosí at altitude and in appalling conditions, could not function without coca, and the colonial economy depended on their output. The Spanish quickly reversed course, not only permitting coca cultivation but taxing and monetizing it. By the seventeenth century, Spanish colonial administrators were tithing coca harvests to fund the church. The sacred Andean leaf had become a commodity of empire.

The European fate of coca diverged from its Andean life entirely. German chemist Albert Niemann isolated the alkaloid cocaine from coca leaves in 1860, naming it after the plant. Within two decades, cocaine was being added to patent medicines, wines (Vin Mariani, favored by Pope Leo XIII), and, in 1886, to an early formulation of what would become Coca-Cola. The soft drink removed cocaine from its formula around 1903, but continues to use decocainized coca extract as a flavoring ingredient — making Coca-Cola the only legal importer of coca leaves into the United States today. The Quechua word kuka has thus traveled from Andean sacred shrub to colonial commodity to alkaloid to soft-drink ingredient, each transformation compressing more distance between the leaf and the name.
