The liver and lemon are LOVERS! A slice of lemon in a glass of water first thing in the morning is great for the liver. I did this for a few years after having liver cancer. Now 26 years later (and 5 children) I am still healthy.
I just wouldn't use lemon juice,because you never know what will happen. You need to call your doctor and ask him the question's,because you may get the answer yes and it hurts your liver...your liver is very sensitive..
