I can understand your enthusiasm since you are encouraged to hear about such a medicine which can repair the damaged liver.But the fact is that there is no such FDA approved medicine which can make a damaged liver normal.
There is lot of claims of these herbal or non herbal medicines,regarding their liver healing capabilities,but there is no scientific data available suggesting that.
It is always better to abide by your doctor's instruction and you should think in terms of getting a liver transplant
for your mother.lest it becomes very late.
Once the condition deteriotes,then it may be too late even for the liver transplant.
I hope it helps.
