Derivation of the botanical name:
Euphorbia, Εὔφορβος, Euphorbus, after the Numidian physician Euphorbus, physician to Juba II, King of Numidia and Mauretania, about the end of the first century BCE. In classical Greek ευφορβοσ (euphorbos) means well fed.
helioscopia, Greek êlios, ηλιοσ, the sun; skopia, σκοπια, observing, looking out; referring to the habit of the flower heads of turning towards the sun.
spurge from the Old French word espurgier (Latin expurgare), which means "to purge." The sap of many herbaceous Euphorbia species have traditionally been used as a purgative, or laxative.
Plants contain white lacteal juice.
