Have you tried any of the following? Ayurveda. Traditional Chinese medicine. Naturopathy. Integrative medicine. These four branches of health sure helped me. Some medical doctors (M.D.s) practice integrative medicine. You can find one on IFM.org. I'm not saying this would help, but it might be worth a try.
Father, we pray for Aunt VC to be healed from kidney and liver problems. AMEN!
Please provide a miracle. Heal VC. Comfort her and her family. Let your presence be felt.
