This recipe is like a tonic for the liver and will help a little. But, when flushing the liver, if you want to see bunches of tones in the toilet, the more oil you use, the bigger the response of bile . The bigger the amount of bile is needed to push bunches of stones out of the bilary ducts.
Also, the purpose of the Epsom Salts
doses before hand are preparatory so the biliary ducts are relaxed, in case you get a big stone trying to come out.
I have usually seen lemon juice added to the above formula.
Perhaps you only need a mild tonic.
