Digestive flush : questions

Hi MH,

What is the purpose of your digestive flush? I am referring to the method that is indicated on the link below.

Can it replace liver flush?

In this process, is there any possibility of gallstones getting stuck in bile ducts? Usually, in other liver flushes saw epsom salt being used for this purpose.

If someone is using PWA C (instead of part A or part B), is that ok? In that case, how much of PWA C would you suggest? I have used Part A and B earlier, so actually like the taste of PWA C as well:)

While someone is lying on the left, would you suggest any liver massage also? What could be the process?

Also, curious to know the purpose of grapefruit juice in this process.

Thank you
