This paper summarizes the evidence for 24 different earths utilized as food supplements or medicines by peoples of the Central Andes, based on current market samples and archaeological specimens. The earths include a phyllosillicate cluster, a sodium and calcium earth cluster, a sulfur mineral cluster, and an iron and copper salt cluster. Archaeological evidence for usage of the main minerals dates back at least five millennia
