I don't know what the health issues are, but has he 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 Good luck
Father, we pray for cousin Jeffrey to have healing from health issues. AMEN!
