I have done 17 Liver Flushes in the past 5 years - so I am experienced... I only use 1/4 cup olive oil with 1/4 cup of freshly squeezed lemon juice. I prepare and use this protocol:
I have gotten varying amounts of stones at different times... usually quite a few. I believe it has to do with the moon phases... but more importantly the color of the stool will tell of the success of the liver flush... the color of the stool should be returned to a brown afterward, instead of light tan...
