Remedy

remedy (n.) c. 1200, remedie, “means of counteracting evil of any kind” late 14c., “a cure for a disease or disorder, medicine or process which restores health;” from Anglo-French remedie, Old French remede “remedy, cure” (12c., Modern French remède) and directly from Latin remedium “a cure, remedy, medicine, antidote, that which restores health,” from re-, here perhaps an intensive prefix (or perhaps literally, “again;” see re-), + mederi “to heal” (from PIE root *med- “take appropriate measures”).
