How long ago did you take the Barfoot Herbalist product? It sounds like parasites that I have read about.
My sister had a horrible case of parasites and it took over 2 years of almost constant taking of various combinations of killers and she still is killing them off. One of the products that she took that is very effective and had good results is Para-Cleanse from Nature's Sunshine Products. It can be ordered over the internet. It is a mix of Chinese herbs.
Did your doc say why, in detail, you shouldn't do a liver flush?
The one I have done is the easiest to do and the easiest on your system of all the protocols I have read. It is ok, and even recommended for very very ill people. I'll go find the directions... maybe you could see if the doc thinks this one would be ok for you... BRB
