Jesus Christ is the great physician and the true healer. When he healed sick people, he did not use any medicine whatsoever. He would heal them with just a word.
Jesus also cast out evil spirits from all who were possessed. The unclean spirits obeyed his command, for he was Christ the Lord. The demons came out of the sick and demon-possessed. We can always go to Jesus Christ with our cares and suffering, so that He can heal us and give us peace. What could be better than this?
