The liver herbs help tone, support, nourish the liver and help it to repair damage done to liver lobules and cells due to the presence of stones. It is not essential to take them for the process of liver flushing, but it benefits the liver in its effort to regenerate and rejuvenate. The herbs also have great blood-cleansing properties which reduces the liver's burden to keep the blood clean, healthy and balanced.
The "Cell-ready Minerals" from ENIVA is the product I recommend.
