I can't answer your direct question. Personally, I think that might overload the body with olive oil over time, which would make future full Liver Flushes less productive.
You might look into Tsetsi's mini-flush. Just google her name. The major ingredients are limes, egg yolks, and a tbsp of healthy oil. It is meant to be a short-term mini-flush (up to 5 consecutive days) but the addition of egg yolks is excellent for building up the liver's strength. I suppose, if you wanted to make it a daily health drink, you could dispense with the tbsp of oil. It tastes great.
