I have done 6 Liver Flushes and believe wholeheartedly that they have very much sped up my recovery time. My digestion has improved (vital for candida) as has my general health. Bowel Cleanses will also help get rid of impacted faeces and mucoid plaque (both can house toxins, parasires/candida).
Chinese medicine (very good holistic system compared to the west) calls the liverthe 'chief of staff', due to its many vital functions.
I would highly recommend these cleanses.
A Liver Flush also helps me expell plaque/candida (I think due to the bowel cleansing/ Epsom Salts alkalising effect), so 2 for the price of 1 :)
