Cura te ipsum ("Take care of your own self!" or "Cure your self") is a Latin injunction, urging physicians to care for and heal themselves first, before dealing with patients.
Cura te ipsum was made famous in the Latin translation of the Bible, the Vulgate. The proverb was quoted by Jesus ("Physician, heal thyself"), as recorded in the Gospel of Luke chapter 4:23. Luke the Evangelist was himself a physician.
