hi, i've used ground organic coffee and instant organic coffee for enemas and i don't notice any difference in their effect. why can't you technically use instant coffee, after all isn't caffeine the all important ingredient? i ask because my local supermarket never has ground coffee in stock, i would use it all the time otherwise.
Too much processing and chemical pollutants, who knows what is really in it, and what has been done to it to get it to that grainy point?
I would never do it, as the point of the enema is to clean you and improve health, going as natural as possible is always best. Can you grind real coffee at home? Grinders are cheap, and great for all kinds of things like nuts and spices and herbal preparations.
