My husband has a condition called auto immune liver, he is taking prescribed Prednisone, Imuran, Calcium, vit D3 for it. In addition he is taking Pradaxa, Digoxin for his A fib, Colazol for Ulcerative Colitis, also Pepcid for Gerd. Do you think Tumeric and Milk thistle are safe to take for his liver? GI specialist said there is no known facts about its benefit. Is that true?
