Liver is also where we store emotions of anger, resentment, deservedness - so I'd wager that the liver-cleansing diet, liver flushes, lymphatic drainage will inherently allow the cue to clear and the body will begin to repair itself. I say again and again though - unless you're working on clearing those corresponding emotions and 'tapes' that keep your body in that loop - it won't clear.
The body does what we tell it to do. If it hears us say 'not yet. not till somebody makes it better. I'm gonna hold this grudge forever' - it'll do it.
