"Clarkia" is not a liver flush but an anti parasite mix. It is made by Dr. Hulda Clark thus the name. What you want is the Hulda Clark recipe for the liver flush. Hers is pretty much the more popular one with a slight modification where folks use Grapefruit juice for the Epsom salts cause it helps to mask the acrid taste of the Salts.
Ask some questions in the liver flush forum and I do believe that her modified recipe (grape fruit juice) is on this site somewhere.
