Yes, there is a cure for all disease and you will be amazed to know that its something we take for granted. It's black cumin, also known as black seed. Take it daily and inshaALLAH all your illness will be cured.
Prophet Muhammad(pbuh) said:
Narrated Abu Huraira: I heard Allah's Apostle saying, "There is healing in black cumin for all diseases except death." [Buhari - Book #71 , Hadith #592]
