On the contrary! The coffee enemas actually stimulates the liver. I also beleive the coffee enema to be a milder and less stressfull of a cleanse then the standard Liver/Gallbladder cleanse! Although I wouldnt do them every day for a long period of time without replenishing the colon with enzymes or probiotics!
I have never done more then three days in a row, but found no ill effects in doing so , any more then that I wouldnt be able to tell you for sure how safe any enema is after that period of time!
Dr Kelly who cured his own pancreatic cancer claims to have done one every day of his life.

I know several people who do daily coffee enemas; I do several weekly myself.

CE's help cleanse and detox your liver and they also cleanse the blood from free radicals.

I'm editing/adding this because I forgot - the best organic coffee for CE's is S.A.Wilsons and they also have a full library of information you can read (and cheap, good enemas supplies too).

s.a.Wilson's Enema coffee for coffee enemas

On the Gerson program, cancer patients do 4 coffee enemas a day. And these very advanced, very weakened cancer patients do great with it. But they also take 13 8-oz fresh-squeezed vegetable juices a day too. That's what makes the coffee enemas safe -- replenishing the electrolytes lost by the coffee enemas with the vegetable juices.

The Gerson organization (www.gerson.org) recommends a ratio of 3 fresh-squeezed vegetable juices for each coffee enema.

I've come to suspect that the same benefits people get from Liver Flushes could be gotten with much less stress to the body through a program of coffee enemas and juices. Just a thought.
