Liver Flushing inconjunction with colonics have cleared my face up tremendously. Andreas recommends do kidney cleanse after 3-4 liver cleanse although i haven't done it yet. You can purchased the kidney tea at http://presentmoment.com/product_info.php?products_id=4941
Also take chinese bitter, chanca piedra, apple juice, or malic acid to break up stones.
You should read Andreas books "The amazing liver cleanse" and the "Keys to Health and Rejuvenation". Those books are great guidelines to follow on your road to better health.
For me, liver flush, colonics and a better diet has been the only thing that has helped my skin problems. Do your research! Look around curezone, there is abundant amount of information to restore your health. Good luck and i wish you love and peace where ever life takes you.
