I have a brother in Mexico that I am helping dealing with cirrhosis. I am not sure if was in the last stage also, but he when 3 times into encephalopaty, (coma), he had problems with blood pressure, and got mentally lost before the coma. He started taking aminociados. Ornithine, and Arginine, I recomend you to search. He also took Milk thistle standarized for a while, Schizandra capsules, Cats claw (Una de gato) He eats a lot af papaya when is available. He stoped eating red meat. He did some Liver Flushes but my sister and I decided no to continue since he was very sick at that time, eventually he is going to start again. Last spring I went to visit him and the only thing that I was not happy with is that he was still having edema in left leg, he was still taking diuretics from the regular doctors, and also did not have control of his bowel, most of the time diarrhea. One of the doctor that saw him suggested to give him Lactulax (laxative). I always disagree that he was supposed to have diarhhea all the time. I decided to sent him some glutamine (and stop the other aminoacids), digestive enzymes, and probiotics, in 3 days the problems with edema and diarrhea when away. Now he is free of bad medicines, all he takes is natural. What I understood when I did my research is that encephaloty happen because the toxicity in your intestines. That is why the doctor recomended to have loose bowel. He got a lot of enemas also to hep to detox the intestines.
