That wasn't my idea or something I picked up here. I research everything I read here. I don't rely on CureZone for information. I have many books and the internet - but I don't believe everything I read either.
David Frahm N.D., (and a whole bunch of other titles) in his book A Cancer Battle Plan the Sourcebook mentions that juice fasting is the best time to do a liver flush. And he has his guests at his 8 day lodge sessions who are on a juice fast do a liver flush. This has been hundreds of people. He didn't make up what he teaches. Dave uses a different protocol for the Liver-Flush he teaches. It uses no Epsom Salts , and much less oil.
When I've done this it was fine. However, I think if a person is sick and dying and doesn't have much time left for this world you would do more things quickly.
I stated what I normally do is wait a week or so after the digestive system is up and running. I'm not sick or in a hurry. To me a week is the end of a fast, as it takes me a week to go off a fast.
