I did 21 Liver Flushes until now. Over the period I tried many
different oils, timing, quantities, body position, mood shape,
moon timing, name it ,. What I think is that your body does what is
right at the time, at the moment. You can't cheat it.
The fact that you were in Poland means that your biological clock
has been altered and when you did your flush over there, your body
was still in "Day" mood. Probably as Hulda Clark explains timing is
critical.(When and in which time zone I ask). BTW I use olive oil from
Italy, Spain, Greece. They sell it all over the world.
In my view, most of the cold pressed olive oils are very similar,
and don't influence the flush at all.
