Liver flush after appendicitis surgery?

Hi everyone

I had my appendicitis operation six months back. Is it safe to do the liver flush? I have constipated for the last six months and my stool is yellow or light brown sometime. I understand my liver might be the underlying problem.

Please tell me is it safe to do the liver flush?

P.S: I dont have any pain in my abdomen and my urine is white colour. I am eating broccoli,orange,cucumber,pears,grape,kiwi,melons and Liv 52 herbal tablet everyday.
