Etymology
The word 'echinacea' is a modern scientific Latin term derived from the Greek root 'ekhinos', meaning "hedgehog" or "sea urchin." This root was borrowed into Latin as 'echinus'. The name was applied to this genus of plants due to the distinctive, sharply pointed, spiny bracts that form the central cone of its flower head, which visually resemble the spines of a hedgehog or sea urchin. The suffix '-acea' is a standard taxonomic ending used to denote a family or group, solidifying its place in botanical classification. Thus, the literal "hedgehog-like" descriptor evolved into the modern abstract term for both the plant and its medicinal extract.
