This is a good blend to aid those dealing with already existing kidney or gallstones.  These herbs will help pulverize the stones into smaller, more manageable sizes,  establish a mucus layer to buffer the stone exit  and help keep them from forming again. 
Once the stones are dealt with, it's best to use the Liver Strengthening Blend as a maintenence blend to help keep stones from forming in the first place.
