The Medicine of the Prophet or Sunnah Healing is one that is followed heavily in the Middle East and around the world.
Not only did Prophet Mohammad, give us the revelation which was handed down to him from Angel Gabriel that black seed was a cure for all disease, He also told us on how to live and what foods in addition to black seed and honey healed.
You can read this book on the Medicine of the Prophet that I highly recommend.
What about honey?
Look for brands that sell raw, unfiltered, and unprocessed honey. This kind of honey is sometimes an acquired taste, but once you get used to the taste of real, natural honey, you won't want to go back to anything processed ever again.
All of this is the science behind black seed oil and honey. Now for the spiritual healing part of things.
