Cirsium: nombre genérico que deriva de la palabra griega: kirsos = varices ; de esta raíz deriva el nombre kirsion, una palabra que parece servir para identificar una planta que se utiliza para el tratamiento de este tipo de enfermedad. De kirsion, en los tiempos modernos, el botánico francés Tournefort (1656 - 708) ha derivado el nombre Cirsium del género.
ochrocentrum: epíteto latino que significa "con el centro pálido".
