maybe he could just take the olive oil straight I really dont think the grapefruit juice is a necessity(i did not use it and had a successful 1st flush) since the primary pushing out of the stones is due to the phytosterol content of the olive oil
the greeks have been using just olive oil and nothing else to remove liver/gall stones for over five thousand ears
no Epsom Salt or anything just olive oil
sove rain
btw just in case anyone wanted to know I do I'm a medical journalist
