Lots of naturopathic liver-healing/cleansing approaches employ chlorophyll, the green part of plants, essentially, in various forms, but the real scientific data on how effective that is is sketchy at best. (Do a Google search on "chlorophyll and liver" and read what you see.). The best way to heal a liver, assuming it's not infected with a virus or with cancer is to eat a balanced diet, avoid harmful medicines and alcohol, exercise, and allow it to "detoxify" (that word always makes me suspicious when I read it) itself. The liver's an amazing and resilient organ, and, as Fake Boobs told you, liver function and liver enzyme bloodwork will tell you exactly where it stands healthwise.
