The word(s) "heal" appears 16 time(s) in 16 verse(s) in Quran in Mohsin Khan translation.

(11) And We send down of the Qur'an that which is a healing and a mercy to those who believe (in Islamic Monotheism and act on it), and it increases the Zalimun (polytheists and wrong-doers) nothing but loss.

(12) See you not (O men) that Allah has subjected for you whatsoever is in the heavens and whatsoever is in the earth, and has completed and perfected His Graces upon you, (both) apparent (i.e. Islamic Monotheism, and the lawful pleasures of this world, including health, good looks, etc.) and hidden [i.e. One's Faith in Allah (of Islamic Monotheism) knowledge, wisdom, guidance for doing righteous deeds, and also the pleasures and delights of the Hereafter in Paradise]? Yet of mankind is he who disputes about Allah without knowledge or guidance or a Book giving light!

(13) That he or it (Muhammad صلى الله عليه وسلم or the Qur'an) may give warning to him who is living (a healthy minded - the believer), and that Word (charge) may be justified against the disbelievers (dead, as they reject the warnings).

(14) And remember Our slave Ayyub (Job), when he invoked his Lord (saying): "Verily Shaitan (Satan) has touched me with distress (by ruining my health) and torment (by ruining my wealth)!

(15) And if We had sent this as a Qur'an in a foreign language (other than Arabic), they would have said: "Why are not its verses explained in detail (in our language)? What! (A Book) not in Arabic and (the Messenger) an Arab?" Say: "It is for those who believe, a guide and a healing. And as for those who disbelieve, there is heaviness (deafness) in their ears, and it (the Qur'an) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand)."

(16) Their eyes will be cast down and ignominy will cover them; they used to be called to prostrate themselves (offer prayers), while they were healthy and good (in the life of the world, but they did not).
