My first liver cleanse did not work.  I tried Clarks wormwood pills, cloves 
and black walnut plus her zapper and the next liver cleanse worked.  I went 
like three years after the last cleanse when my DR said my blood test had a 
high 
liver enzyme reading.  Tried another liver cleanse and again it did not work.  
I bought a mixture of parasite cleaners at the health food store, took it and 
tried another liver cleanse, worked.  Took Milk Thistle 3 caps. per day and 
the next blood test within one month was all normal readings.  Clark seems to 
be right on in my case.
