The liver is the only organ that has the capacity to rebuild itself ONLY when the environment is suitable. Limiting the amount of toxic load on the body will promote a good environment for the liver to work properly and efficiently. This isn’t rocket science: Eating crap foods, drinking alcohol, drinking unfiltered water, and using chemical-laced substances (cosmetics, cleaners, plastics, etc.), to name a few, are not good for the liver.
Go organic, go green, go natural, go holistic, go straight-edge, go whatever you want to call the process of creating a healthier environment for a healthier body.
