Liver flushing alone, while essential for good liver health when the liver is impaired, will not cure liver disease. Proper diet (such as lots of good organic vegetables and fruits), exercise, the right supplements (and not too many supplements!) and a long determined effort is likely what it will take.
A diseased liver, such as an enlarged fatty liver like I have, does not normally happen overnight. It takes years to develop (in my case quite a few years of partying a bit too much with ol Jack Daniels and Jose Cuervo and the like plus not watching my diet or lifestyle as I should - and taking until I had passed the age of 40 to realize that I was not going to be immortal after all). It may well be that it will also take years to correct.
