 Juba II had given the Canary Islands that name because he found particularly ferocious dogs ("canarius" – from "canis" – meaning "of the dogs" in Latin) on the island.Juba's Greek physician Euphorbus wrote that a succulent spurge found in the High Atlas was a powerful laxative.In 12 BC, Juba named this plant "Euphorbia" after Euphorbus, in response to Augustus dedicating a statue to Antonius Musa, Augustus's own personal physician and Euphorbus's brother.
