I had a very sick liver when I started flushing. After 7 or 8 flushes, I took milk thistle for 16 days and thought it was trying to kill me.
If one is very congested, there is nowhere for the toxins to go when released from the cells.
I have been on MHs Liver-Gallbladder Balance which encourages bile production and release and do fine with it.
