I feel the need to interject something here. After just going through it I have found that, without a clean liver (I am ready to do my 30th liver flush) I would never have been able to get out all the parasites that I did recently. My liver had been too highly congested.
I did a parasite cleanse before starting my liver flushing protocol and got out nothing. If you have any parasites in your liver, the herbs, in my opinion, cannot reach them if you have allot of congestion in the hepatic ducts.
So, maybe a good protocol would be, once before you start your liver flushes and once after you have reached the point where you are fairly certain your liver is clean.
