-With regard to cures for various diseases, the Quran is a healing for the believers. This includes healing the heart (mental or spiritual disease) and physical healing. Allah mentions honey in the Quran and says that it is a healing for mankind. And He mentions the principle of preserving good health and guarding against sickness. -So whoever says that the Quran says a lot about medicine in this regard is right, but whoever goes beyond that is a kind of exaggeration coined by some Muslims. -The Quran is not a book of medicine. There are some diseases that did not exist previously, so how could their cure come before they had appeared?
