Cura te ipsum

Cura te ipsum ("Take care of your own self!") is a classic injunction, urging physicians to care for and heal themselves first, before dealing with patients.

This Latin dictum is relevant in many "traditional" societies in which only medicine men who already suffered from a given disease are allowed to cure it.

Cura te ipsum  was made famous in the Latin translation of the Bible, the Vulgate. The proverb was ascribed to Jesus, recorded in the Gospel of Luke chapter 4:23. Luke the Evangelist was himself a physician.
