Question

ever? after damage has been done

Answer 1

what damage are you refering to?

FYI: one of the functions of liver is detoxification

Answer 2

The best thing you can do to detox your liver (it is a gradual process) is to eliminate toxins from your environment.  Get rid of chemicals cleansers, shampoos, soaps, colognes, air "fresheners," Febreeze, fabric softeners, and replace them with natural alternatives.  (Almost everything can be cleaned with vinegar and baking soda, and Whole Foods sells natural health care products.)  

Eliminate processed, packaged foods from your diet and cook, using organic foods.

Consume some form of raw produce daily, and drink lots of filtered water.
