You don't need ozonated oil, that is an old recipe.
There are different protocols the liverflush also cleans out parasites. I would first do the Liver-Flush so when you do the parasite cleanse the dead parasites, if you have any, don't clog up your liver. You don't need the walnut.
Just make sure that you follow the waterdrinking method of Andreas Moritz . Keep drinking water after 2 pm up till 20 min before the ES and again 20 min after the ES.
Sometimes people got dehydrated because they stopped drinking at 2 pm.
