king's evil (n.)youdaoicibaDictYouDict[king's evil 词源字典]
"scrofula," late 14c., translates Medieval Latin regius morbus; so called because the kings of England and France claimed to heal it by their touch. In England, the custom dates from Edward the Confessor and was continued through the Stuarts (Charles II touched 90,798 sufferers) but was ended by the Hanoverians (1714).[king's evil etymology, king's evil origin, 英语词源]
