It is often said that there are great healing powers in the Names of God. But the effect of healing comes from active participation with the meaning of these names and not just mindless recitation. Reminds me of a Sufi Story I recently came across:Past the worshipper as he prayed came 3 people. The crippled, the beggar and the beaten. Seeing them he cried, "Great God, how is it that a loving creator can see such things and yet do nothing about them?" And God said, "I did do something. I made you."
