I did several mini flushes this past summer using limes (lemons), eggs, and just a tablespoon of olive oil.
I will look for the recipe but you can go to telman's blog and he has it posted there under lime/egg/olive oil (I think that is out it is written up).
It is very gentle and I did pass a few liver flukes while on it. You will drink this every morning for a week and then wait a bit before starting again. Calls for an enema a few hours after drinking the mixture.
RG answered an email that I sent to him last week. I think that this is one of his busiest times of years. You could try emailing him your question...
